The Income!Tax Act 1942 and the States Grants (Income Tax Reimbursement) Act 1942 are respectively within the powers of the Commonwealth Parliament to make laws with respect to taxation and to grant financial assistance to any State, notwithstanding the condition of abstinence from imposing income tax attached to such grants under the last-mentioned Act. The two Acts men- tioned, whether considered separately, together, or in conjunction with sec, 31 of the Income Tax Assessment Act 1942 and the Income Tax (War-time Arrange- ments) Act 1942, are not invalid as being legislation directed towards destroying or weakening the constitutional functions or capacities of the States or as involving discrimination contrary to sec. 51 (ii.) of the Constitution or prefer- ence contrary to sec, 99. So held by Latham C.J., Rich, McTiernan and Williams JJ., Starke J. agreeing as to the validity of the Income Tax Act 1942 but dissenting as to the validity of the States Grants (Income Tax Reimbursement) Act 1942. Per McTiernan J.: The Acts are also justified by secs. 51 (vi.) and (xxxix.) of the Constitution. The Commonwealth Parliament under its powers to make laws with respect to taxation has power to make Commonwealth taxation effective by giving priority to the liability to pay such taxation over the liability to pay State taxation, Sec. 31 of the Income Tax Assessment Act 1942 on its true construc- tion has the effect of giving such priority as regards Commonwealth taxation on the income of any year over State taxation on the income of the same year only, and so construed is within power. So held by Latham C.J., Rich, Starke and Williams JJ.; McTiernan J. deciding that the section (which is preceded by a recital that it is passed for the better securing of the revenue required for the efficient prosecution of the present war and is expressed to have opera- tion only until the last day of the first financial year after the end of the war) is within the power of the Commonwealth Parliament to make laws with respect to the naval and military defence of the Commonwealth and the several States and that as the section was a valid exercise of the power which Parliament purported to exercise in passing it, it was unnecessary to decide whether the section was valid under sec. 51 (ii.) and (xxxix.) of the Constitution. The Income Tax (War-time Arrangements) Act 1942 enables the Common- wealth to take over from the States their officers, premises and equipment concerned with the assessment and collection of income tax and provides for the transfer from the States to the Commonwealth of records relating to Common- wealth income tax. The Act is to continue in operation until the last day of the first financial year after the present war. Held, by Rich, McTiernan and Williams JJ. (Latham C.J. and Starke J. dissenting), that the Act is a valid exercise of the power of the Commonwealth Parliament to make laws with respect to the naval and military defence of the Commonwealth and the several States. So held, however, without deciding whether the provisions of the Act for the determination of compensation for the possession and use of premises and equipment by an arbitrator appointed by the Governor-General and for the States' right to access to those records 65 C.L.R.] OF AUSTRALIA. which relate to State income tax constitute just terms within the meaning of H. ©. or A. sec. 51 (xxxi.) of the Constitution. Evidence of speeches made in Parliament or of the report of a Committee on which legislation is based, adduced to show the purpose or intention of ' Parliament or the existence of a '"'scheme" of legislation, is irrelevant to the determination of the validity of legislation and inadmissible. So held by Latham C.J., Rich, Starke, McTiernan and Williams JJ. Relevance of the object and consequences of legislation to the determina- tion of its nature and validity discussed. Effect of the existence of a "scheme" of legislation in relation to the validity of component Acts, considered. APPLICATIONS for interlocutory injunctions ordered to be argued before a Full Court and by consent treated as the trials of the actions. The States of South Australia, Victoria, Queensland and Western Australia and the respective Attorney-Generals of those States in separate actions sued the Commonwealth and Joseph Benedict Chifley, the Treasurer of the Commonwealth for (a) a declaration that the whole, or some one or more, or some part or parts of (i) the States Grants (Income Tax Reimbursement) Act 1942, No. 20 of 1942 ; (ii) the Income Tax (War-time Arrangements) Act 1942, No. 21 of 1942; (iii) the Income Tax Assessment Act 1942, No. 22 of 1942 ; and (iv) the Income Tax Act 1942, No. 23 of 1942, were, or was, ultra vires the Commonwealth Parliament and were, or was, uncon- stitutional and invalid ; and/or that the scheme of uniform taxation embodied in those Acts was unconstitutional and invalid; and (6) an order or injunction to restrain the defendant Treasurer and other Ministers and Commonwealth officers from taking over compul- sorily any of the officers of the plaintifi's taxation department and any of the office accommodation, furniture or equipment of that department or the returns or records held by the department relating to the assessment or collection of income tax and from putting the said Acts, or any of them, or the said scheme, into operation. All the four Acts referred to were assented to on the same day. The States Grants (Income Taw Reimbursement) Act 1942, No. 20, provides by sec. 4: " In every financial year during which this Act is in operation in respect of which the Treasurer is satisfied that a State has not imposed a tax upon incomes, there shall be payable by way of financial assistance to that State the amount set forth in the Schedule to this Act against the name of that State, less an amount equal to any arrears of tax collected by or on behalf of that 1942. a) Sourn AUSTRALIA v. THE ComMon- WEALTH. 376 HIGH COURT [1942. Bb aie A. State during that financial year." Sec. 5 provides that any arrears i collected shall be paid as "' further financial assistance " to eligible sourn States immediately prior to the expiration of the Act and in the Austraria meantime shall bear interest. Upon the Treasurer, after considermg es a report by the Commonwealth Grants Commission, being so coe satisfied, such further financial assistance as the Treasurer thinks fit rart* must be granted to the State or States concerned (sec. 6). Payments are to be made out of the Consolidated Revenue Fund, which is thereby appropriated accordingly (sec. 7). The Act is to " continue in operation until the last day of the first financial year to commence after the date on which His Majesty ceases to be engaged in the present war, and no longer" (sec. 8). In the schedule appears the following: New South Wales, £15,356,000; Victoria, £6,517,000 ; Queensland, £5,821,000; South Australia, £2,361,000; Western Australia, £2,546,000; Tasmania, £888,000; (Total) £33,489,000. The Income Tax (War-time Arrangements) Act 1942, No. 21, contains a recital that it is " An Act to make provision relating to the collection of taxes during the present war," and is prefaced by a preamble which states that "with a view to the public safety and defence of the Commonwealth and of the several States and for the more effectual prosecution of the war in which His Majesty is engaged, it is necessary or convenient to provide for the matters hereinafter set out." Sec. 4 provides: "The Treasurer may, at any time and from time to time, . . . by notice in writing addressed to the Treasurer of any State, notify him that, as from the date specified in the notice, it is, in his opinion, necessary for the efficient collection of revenue required for the prosecution of the war, for the effective use of manpower, or otherwise for the defence of the Commonwealth, that any officers of the State service specified in the notice who have been engaged on duties which, in the opinion of the Treasurer, are connected with the assessment or collection of taxes upon incomes should be temporarily transferred to the Public Service of the Commonwealth, and any officer so specified shall, by force of the notice, be temporarily transferred to the Public Service of the Commonwealth accordingly as from that date." Other sections provide for the retransfer of officers after the Act ceases to operate, for the preservation of the rights of officers, for the control of them while serving the Commonwealth, retirement and superannuation rights. Sec. 11 enables the Commonwealth, upon the Treasurer giving to the State Treasurer a notice similar to that already mentioned, to acquire the possession and the use of "any office accommodation, furniture and equipment specified in the notice." ? _ 65 C.L.R.] OF AUSTRALIA. Sub-sec. 2 of that section provides that the compensation for such H. C. or A. possession and use shall be as agreed between the Commonwealth and the States or as determined by an arbitrator appointed by the Governor-General. Sec. 13 provides for the transfer to the Common- wealth, as from the commencement of the Act, of all returns and records relating wholly or in part to the assessment or collection of Commonwealth income tax which are in the possession of a State. Sec. 14 is a penalty section. The Act is to continue in operation during the same period as that prescribed for Act No. 20. Sec. 31 of the Income Tax Assessment Act 1942, No. 22, inserts a new sec. 221 in the Income Tax Assessment Act 1936-1941. That section provides: "(1) For the better securing to the Common- wealth of the revenue required for the efficient prosecution of the present war—(a) a taxpayer shall not pay any tax imposed by or under any State Act on the income of any year of income in respect of which tax is imposed by or under any Act with which this Act is incorporated until he has paid that last-mentioned tax or has received from the Commissioner a certificate notifying him that the tax is no longer payable." Sub-sec. (1) (b) gives effect to the Com- monwealth priority in payment of income tax in bankruptcy and in the liquidation of a company, and provides a penalty for infringe- ment of the section. Sub-sec. 2 provides that this section is to have operation during the same period as that prescribed for Acts Nos. 20 and 21. The Income Taa Act 1942, No. 23, imposes Commonwealth income tax at very high rates rising to 18s. in the £1 upon that part of any income from personal exertion which exceeds £4,000, and upon that part of any income from property which exceeds £2,100. By sec. 3 the Income Tax Assessment Act 1936-1942 is to be incorporated and read as one with the Income Taw Act 1942. By sec. 7 (1) the tax imposed by the Income Tas Act is to be levied and paid for the financial year beginning on Ist July 1942. Sec. 7 (2) provides that until the commencement of the Act for the levying and payment of income tax for the financial year beginning on Ist July 1943, the Act shall also apply for all financial years subsequent to that beginning on Ist July 1942. Upon applications made pursuant to notice by the first three named States and their respective Attorney-Generals, Latham C.J. ordered that the plaintiffs deliver a statement of claim within a specified period and that the defendants plead thereto within a further specified period, and, upon this having been done and certain affidavits filed, his Honour, by consent, ordered that, subject to all proper objections which might be taken to the affidavits, the 1942.

An order referring to the Full Court, for argument upon the pleadings, affidavit and exhibit referred to therein, the case brought by the State of Western Australia and its Attorney-General was also made upon a summons taken out by, them. The statements of claim filed on behalf of the plaintiffs were, except as to reference in the appropriate places to the particular State concerned, drawn in similar terms. The statement of claim filed on behalf of the State of South Australia and the Attorney- General for that State was substantially as follows :— 1. For many years prior to the establishment :of the Common- wealth of Australia and until the present time the State of South Australia has raised annual revenues by means, inter alia, of taxes upon the incomes of its subjects. 2. The State of South Australia maintains a department for the collection of State income taxes, in which a large staff is employed consisting of officers, the senior members of whom have spent many years in the department and thereby acquired a specialized know- ledge of the administration of the State's income tax Acts. The department uses for the purposes of its work large numbers of type- writers, adding machines and other mechanical equipment. The department is housed in extensive offices in Adelaide, and in the present conditions it would be impossible or impracticable to replace the personnel or equipment of the said department or to find other suitable premises for its accommodation. 3. The several States of the Commonwealth have at all material times depended upon annual revenues raised by taxation for carrying out their governmental functions, and without the revenues from the said taxes the said States would have been incapable of perform- ing their constitutional functions as constituent States of the Commonwealth, 4, The particulars of the revenues and expenditure of the said States are set out in public records, namely the financial statements of the Treasurers of the said States presented to their respective Parliaments for the financial year ended 30th June 1941. In the State of South Australia the principal sources of taxation revenue are and have been for many years past succession duties, land tax, income tax, stamp duties, motor vehicles tax and licences. 5. The following schedule compiled from the said financial state- ments shows the total amount of revenue raised by each State from taxation for the year ended on 30th June 1941, the total amount of revenue raised by each State from income tax, and the proportion 65 C.L.R.] OF AUSTRALIA. which the reyenue from income tax bears to the total revenue from H. ©, oF A. all taxes in each State, bps A. 13, B. as Sas Total Taxes on Percentage Avusrraia Tax, income. of A. ea es £ Common- New South Wales .. 24,535,000 16,696,000 67.8 WHA Nictora, > Ne 12,548,000 6,596,000 52.6 Queensland one 9,180,000 G2a6,0008.

Since the year 1915 the Commonwealth Parliament has levied annual taxes upon income for Commonwealth purposes, and in the year ended 30th June 1941 the Commonwealth raised by means of such taxes the sum of £43,305,000. 7. For some years past the respective taxation departments of all the States except Western Australia have collected on behalf of the Commonwealth the income tax assessed by the Commonwealth on taxpayers in the respective States pursuant to the Commonwealth Income Tax Collection Act 1923-1940. In the case of Western Aus- tralia the Commonwealth collects income tax on behalf of that State pursuant to arrangements made under that Act. In each State there is only one staff for the assessment and collection of both State and Commonwealth income taxes. The taxpayers make only one return, in which there are two columns, one for particulars for State income-tax purposes and the other for particulars for Commonwealth income-tax purposes. Besides the said returns the said depart- ments have in their possession complete records relating to taxpayers made over a long period of years which records are essential to the proper assessment and calculation of the taxpayers' future income tax. Such records relate to both State and Commonwealth tax. _ 8. On 7th June 1942 the following Acts having been passed by the Commonwealth Parliament received the assent of His Excellency the Governor-General and purported to become part of the statute law of the Commonwealth, viz., (w) The Income Tax Act 1942, No. 23; (b) The Income Tax (War-time Arrangements) Act 1942, No. 21; (c) The Income Tax Assessment Act 1942, No. 22; and (d) The States Grants (Income Tax Reimbursement) Act 1942, No. 20.

The amounts set forth in the schedule to the States Grants (Income Tax Reimbursement) Act 1942 against the names of the respective States are in fact substantially the average of the amounts raised by each State by means of income tax in the financial years of each respective State ended 30th June 1940, and 30th June 1941. 10. The income taxes imposed by the Income Tax Act 1942 will raise and are intended to raise annually revenue of an amount approximately equal to the total of the amounts which would have been raised by the Commonwealth and the several States from income taxes under the existing rates of tax. 11. The said Acts form a single legislative scheme the object, substance, and effect of which is to prevent the State of South Australia and the other States of the Commonwealth from exercising their respective constitutional rights and powers to levy and collect income tax and to make it impossible for such States to levy and collect income tax. 12. The effect of the said Acts regarded as a single legislative scheme is to spread the burden of existing Commonwealth and State income taxes over the taxpayers of the Commonwealth as such and thereby to effect a discrimination between the States and the taxpayers of each State as such by reference to the varying rates of income tax at present in force therein. 13. The plaintiffs say that the said Acts are and each of them is unconstitutional and invalid because—(a) They constitute a single legislative scheme the object of which is to raise revenue for State purposes as well as for Commonwealth purposes ; (6) The said Acts constitute a single legislative scheme the pith and substance of which and the purpose and intention and the practical effect of which, is to make, contrary to the Constitution, the power of the Commonwealth to raise income tax exclusive and to deprive the States of their concurrent constitutional rights and power to raise revenue by way of income tax and to destroy the constitutional rights and powers of the State Parliaments and Governments as integral members of the Federal system established by the Con- stitution; (c) The said Acts constitute a single legislative scheme of taxation which, contrary to the Constitution, effects a discrimination between States and particularly—(i) between those States (if any) which vacate the income-tax field and those whicli do not ; and (ii) between the taxpayers of each State as such by reference to the varying rates of income tax at present in force therein; (d) The said Acts and the scheme embodied therein are a law of revenue and give preference to those States which vacate the income-tax field over those which do not and to taxpayers in some States over 65 C.L.R.] OF AUSTRALIA, taxpayers in other States by reference to the varying rates of income H. ©. or A. tax at present in force therein; (e) The Income Tax (War-time Arrangements) Act 1942 is an unconstitutional attempt to compul- sorily effect the transfer of a department of the Executive Govern- ment of South Australia or alternatively certain indispensable officers thereof to the Executive Government of the Commonwealth and to compulsorily acquire property belonging to the State of South Australia and essential to or used for the purposes of its Executive Government; (f) The Income Taa Assessmenl Act 1942 or sec. 31 thereof, is an unconstitutional attempt to interfere with the duties of the taxpayers of the States to pay taxes for the main- tenance of the Executive Governments of the States; (y) The States Grants (Income Tax Reimbursement) Act 1942 is an invalid exercise of the power of the Commonwealth Parliament to make grants to the States and the condition attached to the said grants is an uncon- stitutional interference with the legislative powers of the States ; (h) The said Acts and each of them are and is beyond the legislative powers conferred on the Commonwealth Parliament by the Con- stitution. The plaintiffs claimed a declaration and an order as set forth above. The defendants demurred to pars. 8 and 13 of each statement of claim on the grounds that the Acts therein mentioned were and each of them was within the constitutional powers of the Parliament of the Commonwealth. They admitted pars. 1, 4, 5, 8 and 9 of the statements of claim, and pleaded to the other paragraphs as follows :— 2. They did not admit that in the present conditions it would be impossible or impracticable for the department referred to to replace the personnel or equipment of that department or to find other suitable premises for its accommodation, Save as aforesaid they admitted par. 2; 3. They did not admit any of the allegations in par. 3; 6. They said that the Commonwealth purposes for which annual taxes upon income had been levied by the Commonwealth had included the making of grants of large sums by way of financial assistance to each of the States. Save as aforesaid they admitted par. 6; 7. They said that many taxpayers were required to make two or more returns and they did not admit that the records referred to were essential to the proper assessment and calculation of the taxpayers' future income tax. Save as aforesaid they admitted par. 7; 10. They admitted that the income taxes imposed by the Income Tax Act 1942 would raise for the financial year 1942-1943 an amount approximately equal to the amounts which would have been raised by the Commonwealth and the several States from income 1942.

They Sourn denied each and every allegation in pars, 11 and 12; and 13. They Ausrratta submitted the questions of law raised to the judgment of the Court. Ten Except as to the admissions contained in the respective defences Common- the plaintiffs jomed issue. Megas Affidavits by the Crown Solicitors respectively of the States of South Australia, Victoria and Western Australia, and by the Com- missioner of Taxes of each of the two first-mentioned States, were filed in support of the various allegations contained in the state- ments of claim. The Public Service Commissioner for South Australia deposed in an affidavit that after the transfer to the Commonwealth of officers, office accommodation, furniture and equipment as referred to above, it would, in his opinion, be imprac- ticable to obtain the necessary staff and to provide the office accom- modation, furniture or equipment necessary to enable the State taxes on incomes of the financial year 1941-1942 to be assessed and collected. In an affidavit by an officer of the Treasury Department, of the State of Victoria, he deposed that he had made careful calculations and estimates of the results of the so-called uniform taxation legislation of the Commonwealth comprised in the four Acts under consideration. He estimated that if that scheme were put into operation the total amount of income tax raised thereby would be about £145,000,000 of which about £60,000,000 would be raised in New South Wales and about £40,000,000 in Victoria. He continued that of the said total sum of £145,000,000 it was proposed that £33,489,000 would be paid to the States as income-tax reim- bursement. If that latter amount were allotted to the States proportionately to the aggregate contributions made by the tax- payers of such States, the allocation to the State of New South Wales would be approximately £14,000,000 and to the State of Victoria approximately £9,000,000, whereas the appropriation pro- vided in the States Grants (Income Tax Reimbursement) Act 1942 is £15,356,000 to the State of New South Wales and £6,517,000 to the State of Victoria. In an affidavit filed on behalf of the defendants the Deputy Crown Solicitor for the State of Victoria deposed that the efficient prosecu- tion of the war had necessitated an unprecedented increase in the expenditure of the Commonwealth, and consequently in the revenue to be raised by taxation. For this purpose taxation on incomes of individuals and of companies had been resorted to in an increasing degree. The taxable capacity of the community had been rising since the outbreak of the present war, largely through the defence 65 C.L.R.] OF AUSTRALIA. expenditure of the Commonwealth. This, he deposed, could be 1. ©. oF A. seen from the increase in income-tax collections of the States, despite decreases in taxation rates. The financial position of the States had been materially eased during the war, owing chiefly to the virtual elimination of unemployment through the expansion of war industries, to the provision by the Commonwealth of certain social services, and to a great expansion of railway revenue arising chiefly from causes connected with the war. The amounts raised by the States from income taxation varied widely from State to State in respect of the amount of income tax per head of population and in respect of the manner in which the burden of the tax was spread over different income levels. By reason of those circum- stances the Commonwealth had not been able to use for its own purposes the full taxable capacity of a taxpayer in a less highly taxed State without imposing an insupportable burden on a taxpayer at the same income level in a more highly taxed State by reason of the aggregate of Commonwealth and State income tax. In some cases, he deposed, the rate of these taxes combined in the financial year 1941-1942 already exceeded 20s. in the £1. Although the taxes imposed in the Income Tax Act 1942 are calculated to raise during the financial year 1942-1943 an amount approximately equal to the total of the amounts which would have been raised during that year by the Commonwealth and the several States from income tax at the rates which have operated during the financial year 1941- 1942, it was estimated that, largely as a result of the rising income level, they would raise a substantial amount more than has been raised during the said financial year 1941-1942. The amount of the increase would be available to the Commonwealth for the purposes of defence. If and so far as the States refrained from imposing income tax during the remainder of the war period, there would be avail- able to the Commonwealth the whole of the increase in the yield of income tax due to the rising income level, derived mainly from war expenditure by the Commonwealth. Previously, this increase had been shared between the Commonwealth and the States. There were at present in the Commonwealth and in the several States some twenty-three distinct taxes on income, most of them differing not only in rate but also in basis of assessment. It was anticipated that to substitute for these diverse taxes the single set of taxes imposed by the Income Taa Act 1942 would, by simplifying the machinery for the assessment and collection of income tax, effect a substantial economy in trained personnel, whose services would thus be released for other duties in connection with the prosecution of the war. With a view to simplifying the machinery for the 1942, — Sourn AUSTRALIA wY THE Common- WEALTH. H. ©. or A. 1942, tava? Sourn AUSTRALIA vw. THE Common- WEALTH.

This request was on each occasion unanimously refused. All the parties consented that the applications for interlocutory injunctions should be treated as the trials of the actions. Certain exhibits annexed to affidavits filed on behalf of the plain- tiffs and being the speeches by the Treasurer of the Commonwealth when introducing into the Commonwealth Parliament the Bills which subsequently became the Acts now challenged, and a report of the Committee on Uniform Taxation, were tendered in evidence and objected to. The objection to evidence was argued :— Ham K.C. (with him Fullagar K.C., A. R. Taylor and K. H. Bailey), for the defendants. Neither the speeches nor the report are admissible in evidence (Administrator-General of Bengal v. Prem Lal Mullick (1); Sydney Municipal Council v.

They are relevant because they demonstrate the existence of a legislative scheme to make the Commonwealth tax exclusive. They show to the Court the object and purpose of the challenged legislation (Attorney-General for Alberta v. Attorney-General for Canada (6) ). They serve to show that the power which the Parliament sought for the ostensible purpose of obtaining revenue for the Commonwealth was here used for some other purpose which was not an authorized purpose, and also to show that the Parliament has attempted to do (1) (1895) L.R. 22 Ind, App. 407.

The Court is of opinion that this evidence, consist- ing of the report of the Committee and the speeches of the Treasurer, is not admissible for any of the purposes mentioned, and the Court accordingly rejects the exhibits and the affidavits in each action. The reasons for rejecting them will be published when the judgment is given. Counsel proceeded to argue in the actions :— Lagertwood K.C. (with him Hannan K.C. and K. L. Ward), for the State of South Australia. An examination of the four statutes under consideration shows that they are in fact a single legislative scheme, and that the substance, purpose and effect of it is to make the Commonwealth Parliament the exclusive taxing authority in the Commonwealth in respect of income tax, and to prevent the States from exercising their constitutional powers in relation to income tax. Sec. 7 (2) of the Income Tax Act 1942 diverges from the practice of making the rate of tax the subject of an annual Act. It is not necessary to wait for a new Act to be enacted to fix the rates. The tax continues at the old rates until a new rates Act is passed. This is important having regard to the provisions of sec. 31 of the Income Tax Assessment Act 1942. In the circumstances, it is a matter of economic impossibility for the States to remain in the income-tax field. The money payable under this Act is not for Commonwealth purposes but is for combined Commonwealth and State purposes. It is obvious that the four Acts together form a scheme of legislation, one is dependent on the other. One of those Acts is a Tax Reimbursement Act. It is a reimbursing of the States in respect of moneys which the Commonwealth has collected for their needs. The moneys so proposed to be " reimbursed " were not intended to be grants for the assistance of the States. The States have not sought assistance, the "need" has been created by the Commonwealth. It is not a grant of the kind contemplated by sec. 96 of the Constitution, and does not come within the power conferred by that section. The provisions of the Income Taa (War-time Arrangements) Act 1942 not only constitute an inter- ference with or hindrance to the executive functions of the States but also, the necessary staff, accommodation, furniture and equip- ment having been taken from them, it is impossible for the States 1942. SH SourH AUSTRALIA v. THE Common- WEALTH AG ROK AY 1942. Qe Sourr AUSTRALIA vw. THE Common- WEALTH. - HIGH COURT [1942. to collect any tax which might be lawfully and properly imposed by them. The defence power conferred by sec. 51 (vi.) of the Constitution cannot be used for the purpose of destroying the constitutional powers, legislative and executive, of the States. The Acts have only one objective, and that is to prevent the States from exercising their income taxing powers. Sec. 11 of the War-time Arrangements Act is discriminatory legislation. By it the Common- wealth, if it exercises the power, proposes to take over property which is only used for income-tax purposes and not other property. The returns and records taken over pursuant to sec. 13 are necessary to the States for the efficient assessment of their future income tax. The Commonwealth has no power to direct its legislation towards a State department specially. The power in the Constitution for the Commonwealth to take over State property is subject to the Constitution. The operation of the Income Taw Act 1942 and the Income Tax Assessment Act 1942, having regard to the word "imposed " in sec. 31 of the latter Act, makes it absolutely illegal for a person ever to pay his State income tax. Sec. 7 of the Income Lax Act provides indefinitely for future years. Income tax is imposed in advance of assessment. It is imposed as soon as the income commences to be earned and is paid by way of weekly or other periodical deductions. There is never a time when all the Commonwealth income tax imposed has been paid, because it is a continuing liability. The four statutes under consideration must be construed together ; their essential subject matter is State taxation in various aspects. The entire subject matter of the States G'rants (Income Tax Reimbursement) Act 1942 is State taxation. It is proved by evidence that the amounts set forth in the schedule to that Act were fixed by reference to State income-tax requirements. The condition of the payment of the amounts so set forth is that the respective States shall vacate the income-tax field, There is a distinction between the exercise to the fullest extent by the Common- wealth of its copyright and bankruptcy powers and the method adopted in connection with taxation in the subject four statutes inasmuch as the power to tax is essential to the Constitution of the States. Neither the Commonwealth nor the States can direct their legislative powers towards destroying or weakening the Constitution, capacity or functions of the other: See the Constitution, secs. 106, 107. In defining the content of a Commonwealth power regard must be had to the Federal nature of the Constitution (D'Hmden v. Pedder (1); Baxter v. Commissioners of Taaation (N.S.W.) (2) (1) (1904) 1 C.L.R. 91. (2) (1907) 4 C.L.R. 1087. 65 C.L.R.] OF AUSTRALIA. The King v. Barger (1); James v. The Commonwealth (2); Andrews H. ©. or A. v. Howell (3) ). The Commonwealth of Australia is a dual system. The Common- wealth has a sphere unto itself, and the States have a sphere unto themselves. So far as possible all the powers must be construed so as to preserve that idea, that is, that subject to sec. 109 of the Constitution the States are much on the same level as the Com- monwealth (Moore, Commonwealth of Australia, 2nd ed. (1910), pp. 506-511). A Parliament with limited powers cannot do indirectly what it is forbidden to do directly (Attorney-General for Ontario v. Reciprocal Insurers (4); Toronto Blectric Commissioners v. Snider (5) ). That principle should be applied to the States Grants (Income Tax Reimbursement) Act, the purported object of which is to make grants to States under sec. 96 of the Constitution whereas its real object is to command and control the income-tax legislation of the States (W. R. Moran Pty. Lid. v. Deputy Federal Commissioner of Taxation (N.S.W.) (6) ). The principle stated in The King v. Barger (7) should be applied here. The Court should have regard to the pith and substance of the Acts under consideration (Attorney-General for Queensland v. Attorney-General for the Commonwealth (8); W. R. Moran Pty. Ltd. v. Deputy Federal Commissioner of Taxation (N.S.W.) (9) ). In ascertaining the subject matter, or the scope or purpose of the legislation, the Court is entitled to have regard to its economic effect (The King v. Barger (10); Attorney-General for Alberta v. Attorney- General for Canada (11)). The effect of the four statutes is to render impossible, from a practical or economic point of view, the taxing of incomes by the States. The power conferred by sec. 51 (i.) of the Constitution of taxation for the peace, order and good government of the Commonwealth refers to taxation by the Commonwealth for Commonwealth purposes. The use of the taxation power deliberately to destroy the Constitution of the States is not an exercise of the taxation power subject to the Commonwealth Con- stitution. Under sec. 96 the question of purpose must be considered. The only authority conferred by that section is to provide financial assistance to States which need it, and not first of all to create that need. Here, not only did the Commonwealth create the need, but (1) (1908) 6 C.L.R. 41, at pp. 65,78. (6) (1940) A.C. 838, at p. 858; 63 (2) (1936) A.C, 578, at p. 611; 55 C.L.R. 338, at pp. 349, 350.

A grant is not a reimburse- ment. The power to tax isa{ udamer +l function of every sovereign and quasi-sovereign body politic, and it 1s an essential ingredient in every Constitution (The King v. Barger (1); The Federalist, Essays Nos. 30, 31, 32, by Alewander Hamilton). By attempting to destroy the power of the States to tax incomes, the Commonwealth Parlia- ment is attempting to destroy a sovereign power of the States and that is contrary, inter alia, to sec. 106 of the Constitution. The question is not one of national defence or national necessities. The Commonwealth Parliament has all the powers it needs in respect of money; it has the fullest powers to acquire money, property and manpower. The extent to which powers are exercisable applies equally to times of peace and to times of war. The Parliaments of the States have the same regard for national exigencies as has the Commonwealth Parliament. If the legislation is to be regarded as taxation legislation then it is not properly framed legislation. If it is to be regarded as grants legislation then it is intermeddling with something which is exclu- sively reserved to the States, namely, the taxation power of the States (In re Insurance Act of Canada (2) ). The purpose of the legislation, as shown by the States Grants Act, is to intermeddle with the power of the States to collect taxes for their own purposes ; and that is made part of the taxation scheme, a scheme which is brought into effect in these four statutes, therefore the whole of the legislation, regarded as taxation legislation, is bad, because the Zax Act itself is linked up with the States Grants Act and was intended to be linked up with that Act. The States Grants Act is bad, therefore the Tax Acts cannot be regarded as properly framed legislation for Commonwealth taxation purposes. The rule in D'Emden v. Pedder (3), that any interference with a State instru- mentality is bad, was probably laid down too widely. Although the rule was again affirmed in Deakin v. Webb (4), and in Bacter v. Commissioner of Taxation (N.S.W.) (5), notwithstanding the decision in Webb v. Outtrim (6), the true principle is that a deliberate and purposeful interference with the functions or capacities of either the Commonwealth or the States, is wltra wires and invalid. This principle was first indicated in Baxter v. Commissioners of Taxation (N.S.W.) (7). In The Federated Amalgamated Government Railway and Tramway Service Association v. New South Wales Traffic Employés Association (Railway Servants' Case) (8) it was held that the ) (1) (1908) 6 C.L.R., at p. 81. (5) (1907) 4 C.L.R. 1087. (2) (1932) A.C. 41, at p. 50.

That 5 1 nciple was applied until the decision in Amalgamated Society of Nigineas v. Adelarde Steamship Co. Lid. (Engineers' Case) (1). In that case the Court denied the principle as laid down in the wide terms of D'Hmden v. Pedder (2), but did not deny the principle that neither the Commonwealth nor the States can purposely direct its or their legislation towards destroying or weakening the functions or capacities of the other : see the report (3). This principle was not dealt with by the majority of the Court in the Engineers' Case (1). It was not necessary to and is quite outside the decision in that case (West v. Commissioner of Taxation (N.S.W.) (4)). The scheme shows an interference with and a discrimination against the States. The discrimination in the grants indicates the purpose of the Commonwealth. The real object of the legislation is to force the States out of the taxing field, The States Grants Act is not conditioned by the needs of the States. It is not a proper use of the grant power. Whatever construction is given to the powers of the Commonwealth those powers are subject to the principle that the State Constitutions must be left intact in their essential ingredients: See Pirrie v. McFarlane (5); Australian Railways Union v. Victorian Railways Commissioners (6); West v. Commissioner of Taxation (N.S.W.) (7); Federal Commissioner of Taxation v. Official Liquidator of E. O. Farley Ltd. (8). The imposing of taxation is an essential function or activity of the States. In order to effectuate its scheme the Commonwealth needs a special power to be conferred upon it, as was the position which resulted in adding sec. 105a to the Constitution: See New South Wales v. Commonwealth [ Nos. 1 and 3] (9). The Commonwealth is endeavour- ing to introduce a unitary system without amending the Constitution. If this scheme be good the State Governments can be completely subordinated to the Commonwealth Parliament (Attorney-General for Alberta v. Attorney-General for Canada (10)). Although the Com- monwealth has the power to impose the tax, the selection or dis- crimination shown in imposing the tax makes it manifest that the object is an ulterior one (Attorney-General for Alberta v. Attorney- General for Canada (11) ). This legislation is intended to put the (1) (1920) 28 C.L.R. 129. (6) (1930) 44 C.L.R. 319, at pp. 389, (2) (1904) 1 C.L.R. 91. 391.

It is not admitted that each of the Sourn four statutes is in itself valid. Each statute was enacted as part Avstratia of a scheme, therefore when considering the validity or otherwise Tye of each statute regard must be had to that scheme (W. R. Moran SouMON, Pty. Ltd. vy. Deputy Commissioner of Taxation (N.S.W.) (2) ). An "invalidity in any one of the four statutes infects each of the other three statutes (Attorney-General for the Commonwealth v. Colonial Sugar Refining Co. Ltd. (3) ). All the powers of the Commonwealth Parliament conferred by sec. 51 of the Constitution are subject to the principle that neither the Commonwealth nor the States must deliberately interfere with essential functions of the other. This follows from the fact that all the powers in sec. 51, including the defence power, are conferred "subject to this Constitution." That principle is not an implied principle, it is a necessary consequence of secs. 106 and 107. It follows, therefore, that the Commonwealth cannot, under the defence power, direct itself to destroying or weakening the essential capacities of the States. The only question considered in Farey v. Burvett (4) was whether there was any limitation on the defence power by reference to the reserved powers of the States; the question as to whether the Constitution itself limited the defence power was not directly discussed in that case but apparently was indirectly referred to (5). A conflict of laws, which under sec. 109 is resolved in favour of the Commonwealth, is a different thing from interfering with the power of the States to pass a law, power being regarded as a governmental function. The operation of the defence power is limited. For example, the Commonwealth could not under the defence power purport to effect a purpose contrary to the provisions of secs. 51 (ii.), (iii.), 116, or 117. The defence power is not bounded only by the requirements of self-preservation as stated in Farey v. Burvett (6), that power is for the defence of the Commonwealth and the States. The question which arises is: Was the power which the Parliament exercised related to its defence power (Andrews v. Howell (7) )? A state of war does not suspend the Constitution (United States v. L. Cohen Grocery Oo. (8); Ex parte Milligan (9); Mitchell y. Harmony (10); Knowlton v. Moore (11) ). This legislation (1) (1937) 56 C.L.R. 390, at pp. 404, (8) cise) 255 U.S. 81 [65 Law. Ed. 411, 516].

The Common- H: ©. or A. wealth has been given the widest powers in relation to finance, which can be exercised for the purpose of the defence of the realm. There is no limit (a) to the taxing power in sec. 51 (ii.) except that of discrimination; (6) to the borrowing power under sec. 51 (vi.), or (c) to the power to acquire property under sec. 51 (xxxi.), other than that the acquisition must be on just terms. There is, therefore, no need for the Commonwealth to make laws as to finance by excluding the taxing powers of the States. The Income Taa Act read in the light of the States Grants Act and of the facts admitted in the pleadings raises taxes for both Commonwealth and State purposes. The power to raise money by means of taxes is for the peace, order and good government of the Commonwealth, and not for that of the States (Moore, Commonwealth of Australia, 2nd ed. (1910), p. 510; Sydney Municipal Council v. Commonwealth (1); West v. Commissioner of Taxation (N.S.W.) (2)). Notwith- standing that a taxing Act must deal with only one subject, it is permissible to have regard to the taxing Act and the appropriation Act together. The War-time Arrangements Act is challenged because it authorizes the taking over of executive departments of the States which are essential to the carrying on of the essential governing functions of the States. It is not an exercise of the defence power, although it purports to be so. All the work necessary for the collec- tion of all the taxation imposed by the Commonwealth and the States is being performed under existing arrangements, and this Act will not effect any saving in manpower or expense. The priority provision in sec. 31 of the Income Tax Assessment Act 1942 is bad (Federal Commissioner of Taxation v. Official Liquidator of E. O. Farley Ltd. (3) ). Notwithstanding his capacity and willingness to pay both a taxpayer who pays his State income tax prior to paying all Commonwealth income tax imposed upon him renders himself liable to a penalty. The Commonwealth has other and proper means for the protection of its interests (Lhe Commonwealth v. Queensland (4); Pirrie vy. McFarlane (5); West v. Commissioner of Taxation (N.S.W.) (6)). The statutes discriminate amongst the taxpayers of the different States, and thus offend the provisions of sec. 51 (ii.) of the Constitution. Taxation is always in relation to persons and the burden is borne by persons, and, if there is a dis- crimination between persons by reference to their residence or connection with a particular State in some way, then that is a discrimination between States. The burden, and also the benefit, (1) (1904) 1 C.LR., at p. 232. (4) (1920) 29 C.L.R. 1. (2) (1937) 56 C.L.R., at p. 686. (5) (1925) 36 C.L.R. 170. (3) (1940) 63 C.L.R., at pp. 304, 305.

The argument addressed to the Court by Mr. Ligertwood on all matters except sec. 31 of the Assessment Act and the question of distribution is adopted on behalf of these plaintiffs with slight supplement. Tf the Court can gather from admissible evidence and relevant considerations that the four Acts are linked with one another, the Court should, in the cireum- stances, give consideration to the operation, the character or purpose of the legislation. A later Act may, in itself, contain material which shows that a prior Act, ew facie a perfect exercise of the taxing power, is not in fact directed to taxing but to destroying the functions of the States or to driving them from a particular field of activity. In such a case if the Court looked at the later Act and thus saw that per se it disclosed the character of the earlier Act at that time the earlier Act is invalid ab initio. The later Act might amount to, in effect, an admission by the legislature that the earlier Act, which was ew facie an income-tax Act, had in fact been directed not to raising income tax, but to destroying a function of the State. If one Act is interconnected with another the Court may look back when consider- ing the validity of each of them (W. R. Moran Pty. Ltd. v. Deputy Federal Commissioner of Tawation (N.S.W.)

C. or A. neutralized, rendered nugatory or nullified, by the use of a power which ex facie gives permission to discriminate (Moran's Case (1) ). An examination of the four Acts discloses their character, operation and purpose. The purpose is to drive the States from the income- tax field of taxation. Therefore those Acts do not constitute an exercise of the Commonwealth power with reference to taxation. The powers under sec. 96 of the Constitution cannot be used to effect a discrimination in a matter of taxation. In the circumstances the true character of the States Grants Act is that it is a law in regard to taxation. If the States Grants Act is an Act of taxation and discriminates, then sec. 51 (ii.) would be the same as the passage in sec. 99, but in the opposite way. Whether there is discrimination under sec. 51 (ii.) or preference under sec. 99 is ultimately a question of fact. There can be discrimination in respect of a State or States by taking money, which, it is admitted, may be the proceeds of income tax, from one State, and giving it by means of any inter- mediate machinery, such as an appropriation Act, to another State. This discrimination is a result of (a) the pronounced difference between the income-tax rates of the various States, (b) the difference in population, and (c) the difference in the income of the citizens of each State. There was no uniformity in respect of State taxation. Therefore, although the rate of the Commonwealth tax is uniform, the results vary by reason of the factors mentioned above and hence discrimination takes place. If the Constitution has forbidden a discrimination or preference, the fact that the money is paid into the consolidated revenue is quite immaterial. Shortly, the Tax Act and the States Grants Act should be read together. So read they each become, or the two Acts combined become, a law with respect to taxation and fall within sec. 51 (ii.) of the Constitution. Further, the States Grants Act, a law appropriating revenue, is a law of taxa- tion, and sec. 99 of the Constitution applies. Maughan K.C. (with him H. J. Henchman and Dr. Ellis), for the State of Queensland and the Attorney-General for that State. The arguments already addressed to the Court are adopted on behalf of these plaintiffs. The substance or the purpose or effect of the War-time Arrangements Act is to make it impossible for the Govern- ment of Queensland to administer its income tax department. That result was intended by the Commonwealth. The taking over under sec. 4 of that Act of all the State taxation officers would render it impossible to perform the vast amount of work required to be done with respect to State income taxation for past years. The various provisions of the Act tend to deprive the State of one of its (1) (1940) A.C. 838; 63 C.L.R. 338. 1942. SH Soute AUSTRALIA Vv. THE Common- WEALTH. H. C oF AS 1942, — Sourn AUSTRALIA v. THE ComMon- WEALTH. HIGH COURT (1942. essential activities and are quite beyond the powers of the Common- wealth under any power conferred upon it by the Constitution. Those provisions constitute not so much an unlawful exercise of power but rather the purported exercise of a power which does not exist. Taxation, and the personnel and equipment for its collection, is an essential service or function which the State must have and be entitled to retain against the will of the Commonwealth. Although the Commonwealth may be entitled under the defence power to call up all and any citizen as such, it is not entitled under that power to call up persons because they are officers of the Public Service of a State. The principle stated in Federated Municipal and Shire Council Employees' Union of Australia v. Melbourne Corporation (1) is unaffected by the decision in the Hngineers' Case (2), because an essential service was not dealt with in the latter case. The Common- wealth cannot take the servants of a State in an essential service as such. The extent of the Commonwealth powers is no greater in times of war than in times of peace. An éxamination of sec. 51 with its thirty-nine placita shows that the powers conferred upon the Commonwealth Parliament under the different placita are vis-a-vis the rest of the Constitution of the same quality, because all the placita in sec. 51 are'" subject to this Constitution." The Constitution recognizes the continued existence of the States. The States are entitled to exist notwithstanding anything the Common- wealth Parliament can and may do under the defence power or the taxation power. The States Grants (Income Tax Reimbursement) Act, as its title connotes, is an Act for the reimbursement by the Common- wealth of the States in respect of income tax. The so-called grant is not a grant of financial assistance within the meaning of sec. 96 of the Constitution. It does not satisfy the States' needs, because the need was created by the Commonwealth itself. Although the Commonwealth has large powers of making grants under sec. 96, it is not at liberty to use sec. 96 as a means, in effect, of compelling submission by a State to the surrender of its constitutional powers. Looking at the scheme as a whole, the Commonwealth has taken such a course of action that the State is not able to pursue its ordinary course, its inherent right of imposing income tax, and then, the Commonwealth, having put it in that position, deliberately proposes to reimburse it. Sec. 5 of the States Grants Act cannot be construed as granting financial assistance to a State. The payment of taxation " arrears" at the end of the war, is not financial assistance as con- templated by sec. 96 of the Constitution. The assistance contem- plated by that section is in respect of a presently existing need. The payment so made would not be in respect of the needs of the (1) (1919) 26 C.L.R: 508, at p. 538. (2) (1920) 28 O.L.R. 129. 65 C.L.R.] OF AUSTRALIA. States but because of their rights. Sec. 96, which empowers the H. ©. or A. Parliament to make grants of financial assistance, does not contem- plate the making of such grants by a Minister, or other person, as provided in sec. 6 of the States Grants Act. The word " priority " does not appear in sec. 31 of the Income Tax Assessment Act 1942 and should not be used in connection with it. In re Silver Brothers Ltd. (1) and Federal Commissioner of Taxation v. Official Liquidator of H. O. Farley Ltd. (2) refer to priority of a proprietary character against a fund. It, however, was said in Farley's Case (3) that priorities cannot be given. Those cases refer to an entirely different subject matter and, therefore, are distinguishable on this point. The proper construction of sec. 31 is that it is an absolute prohibition directed to all citizens of Australia who are taxpayers in a particular year against paying their State income tax until they have paid their Federal income tax. The Commonwealth has no power to enact that a person who pays his State income tax before he pays his Commonwealth income tax is guilty of an offence. There is no relation between such a provision and either the defence power or the taxation power. The taxation power in sec. 51 (ii.) relates only to Commonwealth taxation. To purport to prohibit the payment of State taxation is a law with respect to State taxation and is not a law with respect to Commonwealth taxation : See West v. Commis- sioner of Taxation (N.S.W.) (4). It is a question of power, and not of sec. 109 of the Constitution (Stock Motor Ploughs Ltd. v. Forsyth (5) ). A tax is imposed as soon as income is earned, although it is not assessed till later (Commissioner of Stamps (W.A.) v. West Australian Trustee, Executor and Agency Co. Ltd. (6) )—see also Commissioner of Stamps (W.A.) v. West Australian Trustee, Executor and Agency Co. Ltd. (7). Dunphy, for the State of Western Australia, and the Attorney- General of that State. I adopt on behalf of these plaintiffs the arguments already addressed to the Court. The States Grants Act, a statute enacted by the Commonwealth Parliament, is not an appropriation Act. It does not appropriate money for Common- wealth purposes but provides for payment of moneys to States, that is, it appropriates for State purposes. This follows from the joint operation of the Income Taa Act and the States Grants Act. Tn both those Acts there are references to income tax and in sec. 6 of the latter Act the " revenue requirements of the State " is referred to. The two Acts read together are a taxation Act, and therefore, (1) (1932) A.C. 514. (4) (1937) 56 C.L.R., at pp. 686, 687. (2) (1940) 63 C.L.R. 278. (5) (1932) 48 C.L.R. 128, at p. 147.

Sec. 96 cannot be used by the Common- Sour Wealth to circumvent the provision of sec. 51 (ii.) against discrimina- Aveme Ana tion. The money made available to the States under the States Ter Grants Act is not financial assistance but is reimbursement of income Contos: tax collected from the taxpayers of the States. The four statutes BAUTH. should be read as a whole. Regarded as a scheme it is unconstitu- tional because its substance and effect is to make the power to levy income tax the sole jurisdiction of the Commonwealth as opposed to the States. A not inconsiderable proportion of the money raised is to be reimbursed to the States, therefore the taxation is not for defence purposes. If this legislation be valid the same course could be pursued by the Commonwealth in respect to every other form of taxation, and therefore the States can be reduced to financial dependence on the Commonwealth. Such a result is inconsistent with the position of the States under the Constitution. Ham K.C. and Fullagar K.C. (with them A. R. Taylor and K. H. Bailey), for the defendants. Ham K.C. In times of national emergency, as at present existing, the defence power is limited only by the necessity of self-preserva- tion (Farey v. Burvett (1) ). There is no justification for the suggestion or implication that the Commonwealth has perpetrated a sinister scheme aimed at destroy- ing the States or their powers and functions. The duty of the Commonwealth is to protect the States. Under sec. 119 of the Constitution its duty is to protect every State against invasion. The challenged legislation is one way in which it is endeavouring to perform that duty. By this series of Acts, whether together they be described as a scheme or a plan is immaterial, it has endeavoured to marshal the financial resources of the Commonwealth to meet the imminent defence position. For that purpose the Commonwealth Parliament is entitled to impose a very high rate of tax, which is essential for the successful waging of the war, and is also necessarily entitled to obtain what is necessary for the collection of that tax. The collecting of the moneys is not levelled against the States. 'The personnel taken over are not so taken over because they are State personnel and of a particular State department, but because they are the people who are skilled in the work involved in the collecting of the moneys. This vital and urgent work can be done by them quickly and effectively. The purpose of the States Grants Act is that should the high rate of tax imposed by the Commonwealth Parliament render it impolitic (1) (1916) 21 C.LLR., at p. 453. 65 C.L.R.] OF AUSTRALIA. for the States to attempt to impose a tax, grants would be made to HU: ©. oF A. the States so that the States' finances would not be disrupted and they would be enabled to carry on their administration and their services. There is no justification for the suggestion that the Commonwealth will or may take unreasonable advantage of the provisions of the four statutes to the greater disadvantage of the States. It is essential that the Commonwealth Parliament, which is charged with the conduct of the war in all its aspects, should have control of the most essential services, namely, the financial services, and particularly in the matter of the collection of the finances. The taxation provisions now challenged are within the taxation power conferred by sec. 51 (ii.) of the Constitution. They also come within the defence power conferred by sec. 51 (v1.). The real purpose of the legislation is shown upon its face. It is not a colourable scheme whereby under the guise of doing something it was empowered to do the Parliament sought to do something it was not empowered to do, as in The King v. Barger (1); Attorney- General for Alberta v. Attorney-General for Canada (2), and In re Insurance Act of Canada (3)—see also Sonzinsky v. United States (4). These Acts, individually or collectively, are, on their face, Acts for taxation, and to relieve the States from the result of having to suffer a diminution of their respective revenues by reason of not imposing taxation on incomes. The distinction between what is essential and what is not essential is just as impossible to draw as in the Engineers' Case (5). Tn ordinary times the collecting of money may be regarded as only incidentally essential, but now it is very essential that the money should be collected in order that the Commonwealth Parliament may be able to perform that very necessary and essential function of waging the war. All resources should be directed to that purpose (Andrews v. Howell (6) ))s The principles in The King v. Barger (1) and in In re Insurance Act of Canada (3) are applicable only in cases in which either within the four corners of the Act itself it can be seen that it is not for the purpose it pretends to be, or else, looked at in connection with other Acts with which it is connected, that purpose can be found. A consideration of other Acts in Attorney-General for Alberta v. Attorney- General for Canada (2) showed that the real purpose of the Act particularly under consideration was not as expressed therein: See Deputy Federal Commissioner of Taxation (N.S.W.) v. W. R. Moran (1) (1908) 6 C.L.R. 41. (4) (1937) 300 U.S, 506, at pp. 512- (2) (1939) A.C. 117. 514 [81 Law. Ed. 772, at pp. (3) (1932) A.C. 41. 778, 776}. (5) (1920) 28 C.L.R. 129.

The question of purpose, or purposes to be gathered from other Acts, is not applicable to this case. Hach of these Acts must be judged by itself. The Commonwealth Parliament is entitled to exercise the taxation power to the fullest extent (Bank of Toronto yv. Lambe (2) ). It is immaterial that certain indirect consequences, which may have been contemplated and desired by the legislature, flow from the proper exercise of a power (Osborne v. The Common- wealth (3) ). The Court is not concerned with the wisdom or fairness of the legislation. The only question is one of power. It is enough if the legislation can possibly operate for the peace, order and good government of the Commonwealth, either with respect to defence, or taxation, or borrowing, or grants, or matters incidental thereto. If the legislation can possibly operate in respect of any one of these things, then the Commonwealth has power, and it does not matter whether it has used the power wisely or unwisely. If other ways of providing the necessary finance for defence are available, that does not affect the question. It is for the Commonwealth Parlia- ment to determine which means should be applied. It is necessary for the Commonwealth Parliament to be enabled to raise unprece- dented sums of money by income tax, and that implies the necessity for rates of tax which leave very little margin for the taxpayer, and, in case of necessity, the Commonwealth Parliament may require the whole of the available taxable surplus of income. In the war conditions prevailing it was necessary to provide, in financing the defence expenditure and making provision for future necessities, that the Commonwealth Parliament should take control of the imposition and collection of income tax. By enacting this legisla- tion, administration was simplified by avoiding the former multi- plicity of taxes and assessments. It releases for manpower require- ments the surplus personnel employed under the then existing system ; it saves unnecessary expense of administration ; it deters the States from increasing their exactions from the margin left after the Commonwealth requirements are provided for, and it limits the quantum of revenue of the States provided for from this source of their normal requirements as determined by their actual reliance on income tax upon the average of the years 1939-1940 and 1940-1941, or the basis of assistance to the States may be varied if it becomes necessary. The Commonwealth Parliament, in the exercise of a power conferred upon it, may pass an Act which does directly or indirectly affect operations of the States. If the exigencies of the war situation required it the Constitution permits the Commonwealth Parliament to take over (1) (1989) 61 C.L.R., at pp. 759, 760. (2) (1887) 12 App. Cas. 575, at p. 586.

C. or A. the control the Commonwealth Parliament did not purport to prohibit the States, nor did it coerce the States into agreeing to suspend their powers ; but it exercised its own powers under sec. 51 (i), (iv.), (vi.), (xxxix.), and sec. 96. The exercise of those powers drastically affects the practicability of the States continuing to impose or collect income tax; but so as not to disrupt their 1942. Sy Soura AUSTRALIA Vv THE Common- WEALTH. functions or arrangements provision is made to grant financial © assistance under sec. 96. This grant is not a grant of the taxes which the States would otherwise be able to collect under their own taxation. It is politically an undesirable thing that a State should by reason of having a lower tax and yet having to pay the same tax as the others, be put in the position of paying more tax under this scheme than it would have paid if the Commonwealth tax and the State tax had been collected separately. But that is necessitated by the provision in sec. 51 (ii.), that there is not to be any discrimination between the States. The whole tax had there- fore to be spread ratably over the people of the Commonwealth in whatever State they resided; all are required to pay the same tax ratably. The disproportion between New South Wales and Victoria is partly due to the difference in grant and partly to the difference in population and wealth. It is accentuated by the fact that the rate of the State tax in New South Wales is higher (Colonial Sugar Refining Co. Lid. v. Irving (1)). The taxation Acts now under consideration do not discriminate between the States, and that being so it does not matter if the people are required to pay disproportionately. The moneys provided for the States in the States Grants Act were so provided in exercise of the grants power conferred by sec. 96 of the Constitution. That section is silent on the matter of discrimination, and, therefore, grants thereunder may be made on such terms and conditions as the Commonwealth Parlia- ment thinks fit. The provisions of the Tax Act are well within the taxation power. The moneys raised thereunder are paid into the consolidated revenue, and even if some of those moneys were raised for the purpose of making grants, the Act would still be valid, for that is one of the powers and purposes of the Commonwealth. This case is covered by and is an a-fortiori case to Deputy Federal Commissioner of Taxa- tion (N.S.W.) v. W. R. Moran Pty. Ltd. (2). There is not a dis- crimination in favour of States that take the benefit of the States Grants Act as against those which, by continuing to impose income tax, do not: See Massachusetts v.

(3). The two last-mentioned cases definitely lay it down that any inequality resulting not from the law of the Commonwealth but from the different conditions of the States is not a discrimination within the meaning of the Constitution. The only discrimination within sec. 51 (ii) that the Constitution recognizes is a discrimination * between States or parts of States according to their geographical limitations (The King v. Barger (4); Cameron v. Deputy Federal Commissioner of Taxation (Tas.) (5) ). A consideration of the Income Tax (War-time Arrangements) Act shows that it was enacted for the purpose of defence: see particu- larly the recital thereto and secs. 4, 16. In the exceptional state of affairs now prevailing all the matters therein provided for come within the defence power, and are certainly matters incidental to the execution of that power within the meaning of sec. 51 (xxxix.) (Farey v. Burvett (6) ). The Commonwealth Parliament would be neglecting its duty if it did not ensure that the defence of every part of the Commonwealth was under the control of people who, in the opinion of its advisors, were proper and sufficient. If the validity of the Act depends upon the purpose being for the benefit of the war and defence, the Court must be clearly of opinion that the Act is not, and cannot be, for that purpose before it can be declared invalid on that ground. The purpose of the Act is made manifest by its own provisions. The personnel, accommodation, equipment and other matters referred to therein are all part of the national resources and should be available to the Commonwealth for the purposes of defence (Pankhurst v. Kiernan (7)). Regard should be had to the size of the conflict and the imminence of the danger (Andrews v. Howell (8) ). The Commonwealth is in imminent danger and every resource of the Commonwealth should be directed freely to it and not checked by technicalities and imaginary difficulties. The war power is paramount (Northern Pacific Railway Co. v. North Dakota (9); Dakota Central Telephone Co. v. South Dakota (10) ). The tax being a valid tax, it is incidental to it under the power of taxation that the Commonwealth should have a right to acquire an organiza- tion to collect the tax, and, in the exercise of that right, to call upon any citizens to perform that duty. A law cannot be "declared invalid simply because it might be misused. There is no implied prohibition (1) (1926) 38 C.L.R. 399.

C. or A. of its powers of State officers and property (Hingineers' Case (1) ; Attorney-General of New South Wales v. Collector of Customs for New South Wales (2) ). The defence power resides in the Commonwealth and is a very extensive power. Under that power the Common- wealth may take over anything which can conceivably be used for the war purpose (Farey v. Burvett (3) ). The Commonwealth Parlia- ment is the sole repository of the Royal prerogative as regards war (Chatty on The Prerogatives of the Crown, (1820), p. 18, sec.3; Joseph v. Colonial Treasurer (N.S.W.) (4) ; Farey v. Burvett (5) ). The Act, and also the Acts, dealing with separate things, is and are, severable (Acts Interpretation Act 1901-1937, sec. 15a; Huddart Parker Ltd. v. [he Commonwealth (6) ; Deputy Federal Commissioner of Taxation (W.S.W.) v. W. R. Moran Pty. Ltd. (7); Newcastle and Hunter River Steamship Co. Ltd. v. Attorney-General for the Commonwealth (8) ). Grants of financial assistance to the States may be made on such terms and conditions as the Commonwealth Parliament thinks fit, and are therefore unaffected by sec. 99 or any other provision of the Constitution (Deputy Federal Commissioner of Taxation (N.S.W.) v. W. Rk. Moran Pty. Ltd. (9)). The condition of the grants that the States should vacate the income-taxation field is not different in principle from the condition in Victoria v. The Commonwealth (10). A State is not bound to accept the grant. If it regards the condition as too onerous it may continue to impose a tax on incomes within the State. i Sec. 31 of the Income Tax Assessment Act, the " priority " provision, relates to postponing State income tax in a particular year of income, when in respect of that year of income Commonwealth tax is imposed, until the taxpayer "'has paid that last-mentioned tax," which is the Commonwealth tax in respect of the year as to which the State has imposed tax. The section postpones the State tax in a particular year: it is not in respect of any tax that is not assessed. Fullagar K.C. The Tax Act and the Assessment Act are the principal Acts in the scheme. The States Grants Act and the War-time Arrangements Act may be regarded as, in effect, consequential upon the new system of taxation introduced. The conflict between the taxing authorities is only an economical one. There is no constitu- tional limit to the amount the Commonwealth Parliament may seek (1) (1920) 28 C.L.R., at pp. 150, 151, (6) (1931) 44 C.L.R. 492, at pp. 500, 153, 158, 159. 512, 513, 519, (2) (1908) 5 C.L.R. 818.

HIGH COURT [1942. to obtain from the people under its taxation power. The Common- wealth Parliament has power to enact any provision reasonably considered necessary to render its taxing power effective, and has power to bind the States thereby, although, of course, by sec. 114 of the Constitution it is expressly prohibited from imposing a tax on the States. It must follow, quite apart from the incidental power given by sec. 51 (xxxix.), that if the Commonwealth Parliament has power to create an obligation it has power to enact any law necessary to secure the fulfilment of that obligation. Therefore the Common- wealth Parliament was entitled to enact that Commonwealth income tax should be paid in priority to State income tax (Federal Commis- sioner of Taxation v. Official Liquidator of E. O. Farley Lid. (1) ; In re Silver Brothers Ltd. (2)). A law which gives priority to Commonwealth taxation as such is a law with respect to Common- wealth taxation, and therefore valid. A conflict between the Crown in one aspect and the Crown in another aspect was dealt with in Liquidators of the Maritime Bank of Canada v. Receiver-General 'of New Brunswick (3). Whenever the Commonwealth creates rights against itself it is entitled to attach conditions in respect of the protection and exercise of those rights (Lhe Commonwealth v. Queensland (4); The King v. Commonwealth Court of Conciliation and Arbitration (5) ). The same principle must apply to enable the Commonwealth Parliament to legislate to protect and secure the satisfactory performance of obligations to which persons have become subject by reason of Commonwealth law. Sec. 31 of the Assessment Act also is within the defence power. It is required, in the opinion of the Parliament "for the better securing to the Commonwealth of the revenue required for the efficient prosecution of the present war" and has operation "during the present war." The exercise of the defence power cannot be affected by the States (Pirrie v. McFarlane (6) ). The powers conferred by the Constitution should not be construed as limited by considerations of inconvenience or prejudice to the States, or expediency, or imagined abuse (Merchant Service Guild of Australasia v. Commonwealth Steamship Owners' Association [No. 2] (7))—see also Federated Municipal and Shire Council Employees' Union of Australia v. Melbourne Corporation (8). The case of McCulloch v. Maryland (9) affords no ground for any suggestion that State instrumentalities, merely because they are State instrumentalities, are immune from Commonwealth inter- ference.

A similar result seems to have been arrived at in the United States of America (Graves v. New York (3) ). The validity of the Acts cannot be determined in accordance with the order in which they were passed by the legislature. The Commonwealth has the prior call on manpower, and it, is entitled to have the taxation officers before anybody else. If the Commonwealth chooses, it may specify the men it takes by referring to them as employees of a State department, and such a reference does not invalidate the exercise of the general power. This legislation can be defended under secs. 51 (ii.) and 96 of the Constitution. It also can be justified under sec. 51 (vi.). The object of the States Grants Act is to ensure a minimum of dislocation in the States, brought about by the Zaw Act and the Assessment Act. Ham K.C. The case of United States v. Butler (4) is distinguish- able, it was not taxing for taxation purposes ; it was simply the taking of money from one person to give it to another for the carrying out of a policy, and it did not pass through the consolidated revenue. Tn Carter v. Carter Coal Co. (5) the so-called tax was held to be a penalty for not conforming to certain social legislation. In Steward Machine Co. vy. Davis (6) a condition similar to that contained in the States Grants Act was approved. Ligertwood K.C., in reply. On the question of " priority " under sec. 31 of the Assessment Act, it is a misconception to think of income tax as coming out of a person's income. It is a tax in respect of the income and it is paid out of the whole of the person's assets. The section operates to forbid a taxpayer to pay a debt which is lawfully due to the State. The provision is not a law with respect to Common- wealth income tax. That section and also the provisions of the War-time Arrangements Act and the States Grants Act indicate that the scheme is to coerce the States out of the taxation field. Dis- crimination as between the States and the peoples of the States is a pronounced feature of this legislation and it is of the kind for- bidden by sec. 51 (ii.). The taxpayers of some States get less relief from State taxation than the taxpayers of other States. In that respect, this scheme of legislation is the converse of Colonial Sugar Refining Co. Ltd. v. Irving (7). The effect of the States Grants Act (1) (1906) 4 C.L.R. 488, (4) (1936) 297 U.S. 1 [80 Law. Ed. 477]. (2) (1920) 28 C.L.R. 129. (5) (1936) 298 U.S. 238 [80 Law. Ed.

The Commonwealth Parliament is not empowered to use its grants power for that purpose (Steward Machine Co. vy. Davis (1) ). Not- withstanding the necessity the defence power is exercisable only within the frame of the Constitution. The fact must not be lost sight of that this is a Federal system, and that the Governments of the States and the Government of the Commonwealth have co- ordinate powers. That is not implied, it is expressed in the Con- stitution. The financial powers in the Constitution are quite sufficient to provide the Commonwealth Parliament with all the money and all the resources it needs, particularly if the " priority " point be decided in its favour. Therefore there is not any need to attach to the States Grants Act the condition that the States shall vacate the income-tax field. That is the vice not only in that Act but in the whole legislative scheme. Accordingly, the four Acts are bad. The Income Tax Act, being part of the scheme of legisla- tion, cannot stand if the other Acts are declared invalid. The test of its validity is: Would Parliament have passed the high rates of income tax if it had not contemplated that the other three Acts would operate as well (Australian Railways Union v. Victorian Railways Commissioners (2); Huddart Parker Ltd. v. The Common- wealth (3); Vacuum Oil Co. Pty. Ltd. v. Queensland (4); McDonald vy. Victoria (5); Carter v. Carter Coal Co. (6))? The principle contended for by the plaintiffs is not a mere dressing-up of the old doctrine of D'Emden v. Pedder (7) which was supposed to have been overruled in the Engineers' Case (8), but an interpretation of the real principle behind the first-mentioned case in the light of the second-mentioned case as explained in West v. Commissioner of Taxation (N.S.W.) (9). Weston K.C., in reply. Sec. 15a of the Acts Interpretation Act 1901-1937 only deals with the severability of sections in one Act. It is silent on the broader problem of dealing with several Acts which may be said to constitute a scheme if some part or parts of those Acts is or are invalid. On the question of discrimination the criticism relates to the per-capita rates. Comparing the effect upon a high-rated State and a low-rated State, the Commonwealth rate for any given income is lower than the highest rate that prevailed before and higher than the lowest rate.

The following written judgments were delivered :— Laruam C.J. The States of South Australia, Victoria, Queensland and Western Australia and their respective Attorney-Generals sue the Commonwealth and Joseph Benedict Chifley, the Treasurer of the Commonwealth, for a declaration that certain Acts passed by the Commonwealth Parliament are invalid, and for an injunction restraining the Treasurer and other Ministers of State and Common- wealth officers from putting the Acts into operation. Avpplications, supported by affidavits, were made for an interlocutory injunction. Pleadings have been delivered in which, in addition to raising defences, the defendants have demurred to the statements of claim upon the ground that the challenged Acts are within the constitutional powers of the Parliament of the Commonwealth. It was ordered that the cases be argued before the Full Court. All parties have consented that the applications for interlocutory injunctions should be treated as the trials of the actions. The challenged Acts are the following :—States Grants (Income Taa Reimbursement) Act 1942 No. 20; Income Tax (War-time Arrange- ments) Act 1942 No. 21; Income Tax Assessment Act 1942 No. 22; Income Tax Act 1942 No. 23. The plaintifis contend that these Acts constitute a scheme for the purpose of compelling the States to abandon their constitutional right to impose taxation on incomes. The compulsion is brought about by the imposition of a Commonwealth income tax at very high rates, rising to 18s. in the pound upon that part of any income which exceeds £4,000. This Act, it is said, makes it practically impossible for any State to impose a State tax upon income. The amount which, it is contemplated, will be collected under the Com- monwealth Income Tax Act (No. 23) is admitted to be approximately equal to the total of the amounts which would have been raised by the Commonwealth and the several States from income tax under the Commonwealth and State Acts which were in operation up to 30th June last. The result of this Act is that the States, being practically unable to tax incomes, will lose (taking the average) 63 per cent of their total tax revenue. The States which have imposed high income taxes, such as Queensland and New South Wales, will lose 67 to 68 per cent of their total taxation revenue (taken on receipts during the year ending on 30th June 1941), and the States which have imposed relatively lower income taxes will lose a smaller proportion of such revenue—Victoria 53 per cent and Tasmania about 47 per cent. Thus, it is urged, the Common- wealth Income Taw Act places the States in a helpless financial position. VoL. LXV. 28 Isl; (0b Oy A 1942. SH South AUSTRALIA Oe THE Common- WEALTH. July 28. H. C. or A. 1942. Se Sourn AUSTRALIA v THE Common- WEALTH, Latham C.J. HIGH COURT [1942. The Commonwealth Parliament then, it is said, purports to redress the position which it has created by offering grants of money to the States by the States Grants (Income Tax Reimbursement) Act, No. 20. This Act is to continue until the last day of the first financial year after the war (sec. 8). The annual grants are made to each State upon condition of that State not imposing any tax upon incomes in each relevant year (sec. 4). The grants are shown by the title of the Act to be reimbursements in respect of income-tax revenue lost by the States. The amounts have been fixed by taking the average collections of tax by each State during the years 1939-1940 and 1940-1941. Provision is made (secs. 4 and 5) for adjustments in respect of arrears of tax which may be collected by States under past income-tax Acts. It is objected that these Acts constitute an attack by the Common- wealth Parliament upon the constitutional power and function of the States to legislate for the imposition of income tax ; that taxation is not only a normal, but an essential activity of government; that the Commonwealth Parliament has no power to impede, weaken or destroy that activity; and that the Acts are therefore invalid. Other objections are that the Acts involve discrimination contrary to sec. 51 (ii.) of the Constitution, and preference contrary to sec. 99, and that the Grants Act is, by reason of the condition of abstinence from imposing income tax attached to the grants, not a valid exercise of the power conferred by sec. 96 of the Constitution to give financial assistance to States. These objections are, it is contended, supported and reinforced by a consideration of the other two Acts which are challenged. They are relied upon to demonstrate the reality of the "scheme," and, it is argued, they fall with the scheme. But they are also the subject of further specific objections which, it is said, show their invalidity, even if the Acts are not regarded together as constituting a single scheme. ; The Income Tax (War-time Arrangements) Act 1942 No. 21 is prefaced by a preamble which recites that the Act is enacted with a view to the public safety and defence of the Commonwealth and for the more effective prosecution of the war in which His Majesty is engaged. Sec. 4 provides that the Treasurer may by notice in writing addressed to any State Treasurer bring about the temporary transfer to the Public Service of the Commonwealth of any specified officers of the State service who have been engaged in duties which, in the opinion of the Treasurer, are connected with the assessment or collection of taxes upon incomes. A recommendation from the Commonwealth Public Service Board is required, and the Treasurer must in the notice state that the taking over of the officers is, in his Gi) CHER AIP OF AUSTRALIA. opinion, necessary for certain purposes connected with the war or H. ©. or A. otherwise for the defence of the Commonwealth (sec. 4). Other sections provide for the retransfer of officers after the Act ceases to operate, for the preservation of the rights of officers, for the control of them while serving the Commonwealth, retirement, and super- annuation rights. Sec. 11 is intended to enable the Commonwealth, upon the Treasurer giving to the State Treasurer a notice similar to that already mentioned, to acquire the possession and the use of "any office accommodation, furniture and equipment specified in the notice." Sub-sec. 2 of sec. 11 provides that the compensation for such possession and use shall be as agreed between the Common- wealth and the States or as determined by arbitration. Sec. 13 provides for the transfer to the Commonwealth, as from the com- mencement of the Act, of all returns and records relating wholly or in part to the assessment or collection of Commonwealth income tax which are in the possession of a State. Sec. 14 is a penalty section. The Act is to continue in operation during the same period as that prescribed for Act No. 20. The plaintiffs object that this Act cannot be justified under any heading of Commonwealth legislative power, and that it is a direct and deliberate attack upon the essential activities of the States by depriving them of their income tax departments—officers, offices equipment and records, for most of the records relate to State income tax as well as to Commonwealth income tax. Finally, sec. 31 of the Income Tax Assessment Act 1942 No. 22 is challenged. It is at least intended to give priority to the Common- wealth over the States in respect of payment of income tax. The plaintifis contend that, upon the true construction of the section, it does more than that, and that it makes it an offence hereafter to pay any State income tax. It is argued that the Commonwealth cannot give itself priority, and, a fortiori, cannot make it an offence to pay State income tax lawfully imposed. These two latter Acts, it is contended, carry out the scheme which is really sufficiently apparent in the Yaa Act and the Grants Act—a scheme to force the States, against their will, out of the income-tax tax field and therefore to interfere with the powers and functions of State Parliaments in legislation and of State Govern- ments in administering the various services of the States for which taxation revenue—determined in both quantity and quality by State Parliaments—is indispensable. The defendants contend that the four Acts are each valid; that to describe them as a '"'scheme" is merely to use a dyslogistic description which has no legal significance; that, even if they are 1942. ss Soura AUSTRALIA v.

HIGH COURT - {1942. considered as constituting a scheme, they are nevertheless valid ; and that they are properly enacted under powers specifically con- ferred upon the Commonwealth Parliament by the Constitution (sec. 51 (ii.)—taxation, sec. 51 (vi.)—defence, and sec. 96—financial assistance to States). The foregoing summary does not mention all the points which have been argued or all the questions which have been raised—they must be dealt with in due course—but it is sufficient to indicate the nature and importance of the legal problem which is submitted to» this Court. Nature of the Problem.—The problem for the Court is a legal problem which is unknown in countries with a unitary form of government and a supreme legislature. It arises only when legislative powers are divided between legislatures, so that the powers of a law-making agency are limited. That is the case in Australia, where the Common- wealth Parliament, unlike the Parliament at Westminster, depends for its existence and for its powers on a written Constitution. The Constitution says that the Commonwealth Parliament shall have power to make laws with respect to certain subjects (e.g., sec. 51 and other sections such as secs. 73, 77, 78, 79, 96, 122), that it shall have exclusive power to make laws with respect to certain other subjects (secs. 52 and 90), and that it shall not make certain laws at all (e.g., the limitations expressed in secs. 51 (ii.) and (iii.), 92, oe), 114, 116, 117). The Constitution of each State continues, subject to the Commonwealth Constitution (sec. 106), and the State Parlia- ments continue to possess all their powers not exclusively given to the Commonwealth Parliament by the Constitution or withdrawn from them by the Constitution (sec. 107). If either the Common- wealth Parliament or a State Parliament attempts to make a law which is not within its powers, the attempt fails, because the alleged law is unauthorized and is not a law at all. When both the Common- wealth Parliament and a State Parliament have power to make laws then, in case of inconsistency, the Commonwealth law prevails and the State law, to the extent of the inconsistency, is invalid (sec. 109). ' Common expressions, such as: "The courts have declared a statute invalid," sometimes lead to misunderstanding. A pretended law made in excess of power is not and never has been a law at all. Anybody in the country is entitled to disregard it. Naturally he will feel safer if he has a decision of a court in his favour—but such a decision is not an element which produces invalidity in any law. The law is not valid until a court pronounces against it—and there- after invalid. If it is beyond power it is invalid ab imtio. _ 65 C.L.R.] OF AUSTRALIA. Thus the controversy before the Court is a legal controversy, not H. C. or A. a political controversy. It is not for this or any court to prescribe policy or to seek to give effect to any views or opinions upon policy. We have nothing to do with the wisdom or expediency of legislation. Such questions are for Parliaments and the people. It has been argued that the Acts now in question discriminate, in breach of sec. 51 (i.) of the Constitution, between States. The Court must consider and deal with such a legal contention. But the Court is not authorized to consider whether the Acts are fair and just as between States—whether some States are being forced, by a political combination against them, to pay an undue share of Commonwealth expenditure or to provide money which other States ought fairly to provide. These are arguments to be used in Parliament and before the people. They raise questions of policy which it is not for the Court to determine or even to consider. Evidence-—There is no material dispute as to facts. The affidavits which have been filed differ in the opinions which are expressed by the deponents rather than in the facts stated. The affidavits are impor- tant only in so far as they show the state of facts to which the various Acts apply. Most of the facts mentioned in the affidavits can be ascertained by reference to statutes of the Commonwealth and the States containing provisions as to taxation and estimates or records of revenue and expenditure. These facts are conveniently summar- ized in the affidavits, and there is no dispute as to them. Neither is there any dispute as to the intention of the defendants to put the Acts, alleged to be invalid, into operation. That fact is the founda- tion of the plaintiffs' actions. Admissibility of Hvidence—In order to establish the reality of the "scheme" in pursuance of which the Acts are alleged to have been enacted, the plaintifis sought to put in evidence the report of a Committee on Uniform Taxation and speeches made by the defendant Treasurer in Parliament when moving the second reading of the Bills for the four Acts. This evidence was rejected. The words of a statute, when applied to the state of facts with which the statute deals, speak for them- selves. They express the intention of Parliament. A statute may be based upon the report of a committee or of many committees, or upon cabinet memoranda, or upon a resolution of a political party or of a public meeting, or upon an article in a newspaper. The inten- tion of Parliament as expressed in the statute cannot be modified or controlled in a court by reference to any such material. If a statute refers to such material the case is different (Deputy Federal 1942. KY Soure AUSTRALIA v. THE Common- WEALTH. Latham C.J. H. C. or A. 1942, Sy! SourH AUSTRALIA vw THE CoMMON- WEALTH. Latham C.J. HIGH COURT (1942. Commissioner of Taxation (N.S.W.) v. W. R. Moran Pty. Ltd. (1) ; and on appeal (2)). On the general question of the admissibility of reports of commissions &e., see Salkeld v. Johnson (3); R. v. West Riding of Yorkshire County Council (4) ; Assam Railways and Trading Co. Ltd. v. Commissioners of Inland Revenue (5). The practice as to admitting such evidence is the same in the United States, except that the procedure of Congress in relation to the reports of Congressional Committees has led to the admission in evidence of these reports, but only where the language of an Act is doubtful or obscure (Willoughby on the Constitution of the United States, 2nd ed. (1929), vol. 1, pp. 57 et seq.; Railroad Commission of Wisconsin v. Chicago B. & Q. R. Co. (6) ). Reports of speeches in Parliament are also irrelevant and inadmis- sible. There are two Houses of Parliament in the Commonwealth. They consist of one hundred and ten voting members belonging to different parties or to no parties. Members of Parliament frequently have differing opinions, not only as to the merits and real objects of Bills presented, but as to their meaning. Neither the validity nor the interpretation of a statute passed by Parliament can be allowed to depend upon what members, whether Ministers or not, choose to say in parliamentary debate. The Court takes the words of Parliament itself, formally enacted in the statute, as expressing the intention of Parliament (Richards v. McBride (7); R. v. Comp- troller-General of Patents (8); Sydney Municipal Council v. The Commonwealth (9); Administrator-General of Bengal v. Prem Lal Mullick (10)). Possibly the case may be different if the bona fides of Parliament or of the Crown in Parliament can be (Joseph vy. Colonial Treasurer (N.S.W.) (11) ) and is challenged : See the cases referred to in Deputy Federal Commissioner of Taxation (N.S.W.) v. W. R. Moran Pty. Ltd. (12). An interesting example of the irrelevance to the question of the validity of a statute of the motives, objects or intentions of the members of a legislature is to be found in Fletcher v. Peck (13), where it was alleged that members had been bribed and that the legislature was corrupt. In the present case no question of bona fides arises. (1) (1989) 61 C.L.R. 735, at p. 754.

The Acts as a Scheme—In the first place it is contended by H- ©: or A. the plaintiffs that the Acts together constitute a "scheme " directed towards an unlawful object, namely, the exclusion of State Parliaments from the sphere of legislation upon income tax. Reference is made to Attorney-General for Alberta v. Attorney-General for Canada (1), and to Deputy Commissioner of Taxation v. Moran (2). The contention that an Act which does - not refer to or incorporate any other Act, and which when con- sidered by itself is not invalid, may be held to be invalid by reason of the enactment of other Acts, whether valid or invalid, meets many difficulties. Parliament, when it passes an Act, either has power to pass that Act or has not power to pass that Act. In the former case it is plain that the enactment of other valid legisla- tion cannot affect the validity of the first-mentioned Act if that Act is left unchanged. The enactment of other legislation which is shown to be invalid equally cannot have any effect upon the first- mentioned valid Act, because the other legislative action is completely nugatory and the valid Act simply remains valid. It is not necessary, however, in the present case to examine these questions. The Tax Act imposes a tax at rates such that there is left little practical room for State income tax. The Grants Act shows the intention of the Commonwealth Parliament that the Parliaments of the States should cease to tax income. The War-time Arrangements Act shows the intention of the Commonwealth Parlia- ment that the Commonwealth should take over the officers and the physical means which are necessary for administering any system of State taxation upon income. As soon as a State which refused to abandon income tax formed a department to collect the tax the Commonwealth could take it over. Sec. 31 of the Income Tax Assessment Act is manifestly designed to make sure that the Govern- ment collects Commonwealth income tax, whatever may happen to any claim of a State for income tax, but it is independent of the general "scheme" of excluding the States altogether from the income-tax field. The intention to get rid of State income tax and of State income tax departments is clear in the case of the three first-mentioned Acts, and if such an intention is fatal to the validity of Commonwealth legislation it is not necessary to allege or prove any "scheme." Accordingly, in the present case full weight can be given to the plaintiffs' case without any reference to any "scheme." The defendants do not seek to conceal the scheme : they assert it and justify it. There is here no question of any pretence (1) (1939) A.C. 117. (2) (1940) A.C. 838, at p. 849; 63 C.L.R. 338, at p. 341. 1942. Ww Sourn AUSTRALIA v. THE Common- WEALTH. Latham C.J. H. C. or A. 1942. Qe Souru AUSTRALIA OP THE Common- WEALTH. Latham 0.J. HIGH COURT [1942. of doing one thing under the guise of doing another. The legislation which is attacked is not colourable—it admits its character upon its face. The Tax Act—The Income Tax Act is in its terms an ordinary tax Act, except that it imposes a very high rate of tax."It may be assumed, in favour of the plaintifis, that the rates of tax which are imposed make it politically impossible for the States to impose further income tax. But it is not possible for the Court to impose limitations upon - the Parliament as to the rate of tax which it proposes to impose upon the people. There is no legal principle according to which a tax of 10s. in the pound should be held to be valid, but a tax of lls. or 15s. or 18s. or 20s. should be held to be invalid. Indeed, it was not disputed by the plaintifis that, if the Zax Act had been passed without the Grants Act, it would have been unchallengeable, whatever the result might have been in making it impossible for a State to impose or collect income tax. But it is said that if the object of the Tax Act is to accomplish indirectly what the Commonwealth Parliament cannot do directly, the Act is invalid. The object is not only to collect revenue and to make grants to the States, but to prevent the States imposing taxa- tion upon incomes. This, as has been said, appears to be obvious enough. But the validity of legislation is not to be determined by the motives or the "ultimate end" of a statute. In R. v. Barger (1) there was an acute difference of opinion as to the true nature of the legislation there in question. But all the justices agreed that, when a legislative power was granted, neither the indirect effect of its exercise nor the motive or object of the legislature in exercising it were relevant to the question of the validity of its exercise in a particular case: See Barger's Case (majority judgment (2); per Isaacs J. (3); per Higgins J. (4)); Radio Corporation Pty. Ltd. v. The Commonwealth (5). The Tax Act is a law with respect to taxation. It simply exacts from citizens a contribution to the public revenue. It contains no provisions relating to any other matter. The argument which was successful in Barger's Case (1) (that what professed to be a Tax Act was shown by its own terms not really to be such an Act) is not available here. The Act is merely and simply an Act imposing taxation upon incomes. The Commonwealth power to legislate is subject to certain limitations. There must be no discrimination between States or parts of States (Constitution, sec. 51 (ii.) ), the 1) (1908) 6 C.L.R. 41. (4) (1908) 6 C.L.R., at p. 118. ) (1908) 6 C.L.R., at pp. 66, 67.

It is clear that the Tax Act does not infringe any of these provisions. It is argued that the Commonwealth cannot use its taxing power so as to prevent the States exercising their taxing power. It may be conceded that the Commonwealth Parliament has no power to prohibit a State exercising its taxing power. But there is no such prohibition in this Taw Act. As already stated, there is no sure foothold for an argument that the Commonwealth Parliament cannot impose so high a tax in relation to a particular subject matter that there is no room for any additional State impost. This argument was not put by the plaintiffs. The Commonwealth will raise by the Taw Act an amount approxi- mately equivalent to that which would be raised by Commonwealth and State income-tax legislation as formerly operative. The Com- monwealth proposes, under the Grants Act, to reimburse the States for lost income tax by paying to them the sums set out in the schedule to the Act, amounting to £33,489,000. Upon the basis of these facts it is argued for the plaintifis that the Tax Act really raises money for State purposes and not for Commonwealth purposes—to which the power conferred by sec. 51 (ii.) of the Constitution is limited : See Sydney Municipal Council v. The Commonwealth (1). But the reply to the plaintiffs' argument is that the Constitution plainly permits the Commonwealth to raise money in order to pay it over to or for the States: See secs. 87, 89, 93, 94, 96, 105, 105a. Payment of money to the States is clearly a possible and proper Commonwealth purpose. Another argument for the plaintiffs is that the Commonwealth Parliament by its Zax Act excludes the States from necessary sources of revenue, and so itself creates the need for assistance which it then purports to relieve by financial grants. It is urged that such grants do not fall within sec. 96 of the Constitution. But the need for financial assistance to States not infrequently results from Commonwealth policy as expressed in Commonwealth laws (Deputy Federal Commissioner of Taxation (N.S.W.) v. W. A. Moran Pty. Ltd. (2) ; same case on appeal (3) ). Thus the mere fact that a Commonwealth law creates a " need " in a State does not prevent the Commonwealth Parliament from relieving the need by granting financial assistance to a State under sec. 96. It is further argued for the plaintiffs that the object of the Tax Act, at least to the extent of an amount of £33,489,000 of the revenue (1) (1904) 1 C.L.R. 208, at p. 232.

I assume for the purpose of considering this argument that the Grants Act is for some reason invalid. In fact the money raised by the Tax Act is not earmarked in any way. It is doubtful whether Commonwealth revenue can be ear- marked except at the point of expenditure (i.e., not as revenue) by an appropriation Act—and there is no appropriation section in the Tax Act. The Constitution, sec. 81, provides: "All revenues or moneys raised or received by the Executive Government of the Commonwealth shall form one Consolidated Revenue Fund, to be appropriated for the purposes of the Commonwealth in the manner and subject to the charges and liabilities imposed by this Constitu- tion." Sec. 83 provides that no money shall be drawn from the Treasury of the Commonwealth except under appropriation made by law. Separate constitutional provisions apply to appropriation Acts (secs. 54 and 56) and to laws imposing taxation (sec. 55). Sec. 54 provides that: "The proposed law which appropriates revenue or moneys for the ordinary annual services of the Government shall deal only with such appropriation." Sec. 55 provides that: " Laws imposing taxation shall deal only with the imposition of taxation, and any provision therein dealing with any other matter shall be of no effect." : Thus no provision imposing taxation can be included in an appropriation Act and no appropriation of money can be made by any Act imposing taxation. All taxation moneys must pass into the Consolidated Revenue Fund (sec. 81), where their identity is lost, and whence they can be taken only by an appropriation Act. An appropriation Act could provide that a sum measured by the receipts under a particular tax Act should be applied to a particular purpose, but this would mean only that the sum so fixed would be taken out of the general consolidated revenue. Thus there can be no earmarking in the ordinary sense of any Commonwealth revenue. In this case, however, no attempt has been made to provide that any moneys received under the Tax Act shall be applied towards meeting the payments under the Grants Act. Neither Act contains any such provision. The appropriation made by the Grants Act is made out of the Consolidated Revenue Fund (Grants Act, sec. 7). It is not necessary in this case to consider the general question whether the Commonwealth appropriation power is limited so that 65 C.L.R.] OF AUSTRALIA. some appropriations would be invalid, not because of an infringe- H. C. or A. ment of sec. 54 of the Constitution, but because they were applicable to some unauthorized object. But, even if it can be assumed that 1942. a Sourn an appropriation can be invalid (as here contended with reference AvsrRaxia to the Grants Act), such invalidity cannot reflect back upon any tax Act so as to make it invalid. Commonwealth Government receipts consist of proceeds of taxation and loans and of payments for ser- v THE Common- WEALTH. vices, and they all go into one fund (Constitution, sec. 81). Suppose Latham 6.5. the Commonwealth Government were, under invalid legislation, or without any pretended legislative justification, to make a payment of one million pounds or one thousand pounds to a person who had no right to receive it. Can it be contended that because the payment might have been made out of receipts from income tax that therefore the income-tax laws of the Commonwealth are invalid? The argument might with equal force be applied to the customs tariff, or the Estate Duties Act, or the Land Taw Act, or to any Act which brings in the money some of which has been or may have been unlawfully expended. It is impossible to accept a contention the necessary result of which, if logically applied, would be that any unauthorized expenditure of Commonwealth money would invalidate all the Acts under or by virtue of which moneys come into the consolidated revenue. Thus the objections made to the Tax Act specifically must be held to fail. The Grants Act.—It is now necessary to deal with the far-reaching and fundamental general objection which is made to the Taw Act con- sidered in association with the other Acts, but which is particularly directed against the Grants Act. This objection is based upon the following principle which, it is argued, applies to all Commonwealth legislative powers, namely— the Commonwealth cannot direct its legislative powers towards destroying or weakening the constitutional functions or capacities of a State. (A corresponding rule should, it is said, be applied in favour of the Commonwealth as against the States.) In another form the principle is said to be that the Commonwealth cannot use its legislative powers to destroy either " the essential governmental functions " or " the normal activities " of a State. Before considering sec. 4, which is the main provision of the Grants Act, reference may be made to an objection to the validity of sec. 6. This section enables the Treasurer of the Commonwealth, subject to a maximum limit to be stated in a recommendation of the Com- monwealth Grants Commission, to increase the grants to the States. It is objected by the plaintiffs that this provision is not a valid exercise of the power given to the Commonwealth Parliament to H. C. or A 1942, SH Sourn AUSTRALIA uv THE ComMon- WEALTH. Latham C.J. HIGH COURT [1942. - grant financial assistance to States under sec. 96 of the Constitution, because it involves an unconstitutional delegation to the Treasurer of legislative power. This objection, however, is answered by Deputy Federal Commissioner of Taxation (N.S.W.) v. W. R. Moran Pty. Ltd. (1). The principal provision of the Grants Act is sec. 4, which is in the following terms: "In every financial year during which this Act is in operation in respect of which the Treasurer is satisfied that a State has not imposed a tax upon incomes, there shall be payable by way of financial assistance to that State the amount set forth in the Schedule to this Act against the name of that State, less an amount equal to any arrears of tax collected by or on behalf of that State during that financial year." Upon this provision the following preliminary comments may be made :— (a) The Act does not purport to repeal State income-tax legisla- tion. The Commonwealth Parliament cannot do this. It cannot repeal an Act which it has no power to enact: See Attorney-General for Ontario vy. Attorney-General for the Dominion (2); Great West Saddlery Co. v. The King (3). Plainly the Commonwealth Parlia- ment could not enact separate income-tax Acts for separate States. Nor can it repeal such Acts enacted by the States. (b) The Grants Act does not require, in order that a State should qualify for a grant, that the State—or rather the State Parliament— should abdicate, or purport to abdicate, its power to impose taxes upon incomes. A State Parliament could not bind itself or its successors not to legislate wpon a particular subject matter, not even, I should think, by referring a matter to the Commonwealth Parliament under sec. 51 (xxxvii.) of the Constitution—but no decision upon that provision is called for in the present case. The grant becomes payable if the Treasurer is satisfied that a State has not in fact imposed a tax upon incomes in any particular year during the operation of the Acts. (c) The Act does not purport to deprive the State Parliament of the power to impose an income tax. The Commonwealth Parlia- ment cannot deprive any State of that power: see Constitution, secs. 106, 107. Notwithstanding the Grants Act a State Parliament could at any time impose an income tax. The State would then not benefit by a grant under the Act, but there is nothing in the Grants Act which could make the State income-tax legislation invalid. (1) (1939) 61 C.L.R. 735, at p. 763.

C. or A. not to exercise a power the continued existence of which is recognized —the power to impose income tax. The States may or may not yield to this inducement, but there is no legal compulsion to yield. The Commonwealth may properly induce a State to exercise its powers (e.g. the power to make roads: See Victoria v. The Common- wealth (1)) by offering a money grant. So also the Commonwealth may properly induce a State by the same means to abstain from exercising its powers. For example, the Commonwealth might wish to exercise the powers given by the Constitution, sec. 51 (xiii.) and (xiv.) to legislate with respect to banking, other than State banking, and insurance, other than State insurance. The Common- wealth might wish to set up some Federal system of banking or insurance without any State competition. If the States were deriving revenue from State banking or State insurance, they might be pre- pared to retire from such activities upon receiving what they regarded as adequate compensation. The Commonwealth could properly, under Commonwealth legislation, make grants to the States upon condition of them so retirg. The States could not abdicate their powers by binding themselves not to re-enter the vacated field, but if the Commonwealth, aware of this possibility, was prepared to pay money to a State which in fact gave up its system of State banking or imsurance, there could be no objection on this ground to the validity of the Commonwealth law which authorized the payment. But the position is radically different, it is urged, if the so-called inducement practically amounts to coercion. Admittedly the Commonwealth Parliament could not pass a law compelling a State to surrender the power to tax incomes or prohibiting the exercise of that power by a State. Equally, it is said, the Commonwealth cannot lawfully make an offer of money to a State which, under the conditions which actually exist, the State cannot, on political or economic grounds, really refuse. This identification of a very attractive inducement with legal compulsion is not convincing. Action may be brought about by temptation—by offering a reward—or by compulsion. But tempta- tion is not compulsion. A person whose hand is physically propelled by another person against his will so that it strikes a blow is not guilty of assault. But it would be no defence to allege that he really could not help striking the blow because he was offered £1,000 for doing it. (1) (1926) 38 C.L.R. 399, 1942. Saad SourH AUSTRALIA OF THE Common- WEALTH. Latham C.J. H. C. or A. 1942, SH Sourn AUSTRALIA Vv THE Common- WEALTH. Latham C.J. HIGH COURT [1942. This question has been considered in the Supreme Court of the United States of America: See Massachusetts v. Mellon (1), where it was held that a Federal statute making money available to States which were willing to co-operate with Congress in reducing maternal and infant mortality imposed no obligation, but simply extended "an option which the State is free to accept or reject." On the other hand, in United States v. Butler (The Hoosac Mills Case, a New Deal case) (2) it was said that an offer to a farmer the refusal of which may involve financial ruin to him amounts to coercion— "coercion by economic pressure. The asserted power of choice is illusory." Stone J., dissenting with Brandeis and Cardozo JJ., took a contrary view: " Threat of loss, not hope of gain, is the essence of economic coercion" (3). A somewhat similar question, but in a different form, arose in Carter v. Carter Coal Co. (4), where the majority took the view that an offer of exemption from a penalty amounted to compulsion. The authority of the latter two cases is, however, greatly diminished, if not destroyed, by the more recent case of Steward Machine Co. v. Davis (5). A Federal law provided fora rebate to taxpayers of up to 90 per cent of a Federal tax if the tax- payer contributed to a State unemployment scheme approved by the Secretary of the Federal Treasury. It was urged that this was an unconstitutional attempt to coerce the States into enacting unemployment legislation approved by the Federal Government— that Government itself having no power to legislate upon the subject of unemployment. The contention was rejected. It was said :— " Every rebate . . . is in some measure a temptation. But to hold that motive or temptation is equivalent to coercion is to plunge the law in endless difficulties " (6). Sutherland J. (dissenting) agreed in this view :—''I agree that the States are not coerced by the Federal legislation into adopting unemployment legislation. The provisions of the Federal law may operate to induce the State to pass an employment law if it regards such action to be in its interest. But that is not coercion" (7). Thus the now prevailing opinion of the Supreme Court of the United States is in accord with the view which has been stated above. The Grants Act does not compel the States to abandon their legislative power to impose a tax upon incomes. States which do not abstain from imposing (1) (1923) 262 U.S. 447, at p. 480 [67 (4) (1936) 298 U.S. 238: see pp. 310 Ed. 1078, at p. 1082]. et seq. [80 Law.

State Functions and Capacities —It is clear, however, that the Grants Act is intended to bring about the result that the State shall not impose such a tax. The Act therefore must meet the challenge of the plaintiffs that the Commonwealth cannot direct its legislative powers against the constitutional functions or capacities—against the essential functions or the normal activities—of a State. This statement reminds one who has followed the development of Australian constitutional law of "the rule in D'Hmden v. Pedder (1) ", which was stated in the following terms: " When a State attempts to give to its legislative or executive authority an operation which, if valid, would fetter, control, or interfere with, the free exercise of the legislative or executive power of the Commonwealth, the attempt, unless expressly authorized by the Constitution, is to that extent invalid and inoperative " (2). A corresponding rule was held to apply against the Commonwealth in favour of the States in the Railway Servants' Case (3). Thus the doctrine of the reciprocal immunity of Federal and State instrumentalities was introduced. The latter case was overruled in the Engineers' Case (4), and the exercise of Commonwealth legislative powers was held not to be subject to any implied prohibition prescribing non-interference with State instrumentalities, though, as pointed out in the Engineers' Case (5), and again in West v. Commissioner of Taaxa- tion (N.S.W.) (6) (per Dixon J. (7); per Evatt J. (8) ), the nature of the State power or Commonwealth power concerned must be considered in each case. In the Engineers' Case (4) the rule in D'Emden v. Pedder (1), distinctly stated as a limitation upon the exercise of the powers of the States only, was held to be sound on the basis of sec. 109 of the Constitution, which provides that: '* When a law of a State is inconsistent with a law of the Commonwealth, the latter shall prevail, and the former shall, to the extent of the inconsistency, be invalid." Questions relating to ee non-statutory prerogative were left open in the Engineers' Case (9). No question affecting such pre- rogative arises in the present case. It is argued for the plaintifis that the authorities as they now stand leave it open to the Court to hold that, while there is no general principle of exemption of State instrumentalities from the 1904) 1 C.L.R. 91.

It will be convenient to quote certain passages from cases upon which the plaintiffs rely which will show the plaintiffs' contention in its full strength. R. v. Barger. "It is an inherent consequence of the division of powers between governmental authorities that neither authority is to hamper or impede the other in the exercise of their respective powers " (R. v. Barger (1), per Isaacs J.). It should be observed, however, that this statement is completed by the following important addition :— "But that doctrine has no relation to the extent of the powers themselves ; it assumes the delimitation aliunde. It is contrary to reason to shorten the expressly granted powers by the undefined residuum. As well might the precedent gift in a will be limited by first assuming the extent of the ultimate residue" (2). This proposition anticipates the decision in the Engineers' Case (3) that express Commonwealth powers cannot be limited by reserved State powers. Pirrie v. McFarlane. "T can find " (in certain Canadian cases) "no principle governing this case, unless it be the natural and fundamental principle that, where by the one Constitution separate and exclusive governmental powers have been allotted to two distinct organisms, neither is intended, in the absence of distinct provision to the contrary, to destroy or weaken the capacity or functions expressly conferred on the other. Such attempted destruction or weakening is prima facie outside the respective grants of power" (Pirrie v. McFarlane (4), per Isaacs J., quoted by Dixon J. in West v. Commissioner of Taxa- tion (N.S.W.) (5)). In this passage emphasis is placed upon the grant of exclusive powers to both Dominion and Provinces—a feature which is absent from the Commonwealth Constitution. West v. Commissioner of Taxation. "Tt must at least be implied in the Constitution, as an instrument of Federal Government, that neither the Commonwealth nor a State legislature is at liberty to direct its legislation toward the destruction of the normal activities of the Commonwealth or States.

Case (1) of the earlier doctrine of immunity of instrumentalities " (per Hvatt J. in West v. Commissioner of Taxation (N.S.W.) (2) ). "It is quite erroneous to regard the Engineers' Oase (1) as having established a new and valid constitutional principle, under which, either by direct declaration as to the termination of specified State legislation, or as to the States' legislative power, or by indirectly creating conditions or qualities under Commonwealth legislation which will achieve the same objectives, the Commonwealth Parlia- ment is enabled, by the exercise of its own legislative power, to rid itself of any State legislative 'interference' or 'impediment.' This constitutional principle or doctrine is a dangerous feature of the Engineers' Case (1) and any proposed application of it should be most carefully watched " (also per Evatt J. in the same case (3) ). Caron v. The King. "In Great West Saddlery Co. v. The King (4) . . . a general principle was laid down that no Provincial legislature could use its special powers as an indirect means of destroying powers given by the Parliament of Canada. By parity of reason the Parliament of Canada could not exercise its power of taxation so as to destroy the capacity of officials lawfully appointed by the Province" (Caron v. The King (5) ). James vy. The Commonwealth. " The powers of the States were left unaffected by the Constitution except in so far as the contrary was expressly provided ; subject to that each State remained sovereign within its own sphere. The powers of the State within those limits are as plenary as are the powers of the Commonwealth " (James v. The Commonwealth (6) ). The discussion of the question may begin with a consideration of the last-quoted passage. It is unnecessary in the present case— and probably unnecessary in any purely legal controversy—to consider in what sense a State which is part of a Federal Common- wealth under the British Crown can be said to be "a sovereign State': See The Commonwealth v. New South Wales (7), and West v. Commissioner of Taxation (N.S.W.) (8). The legislative powers of the States depend upon their Constitutions, which, speaking generally, give power to legislate for the peace, order and good government of the States. There are certain limitations upon (1) (1920) 28 C.L.R. 129. (6) (1936) A.C. 578, at p. 611: 55 (2) (1937) 56 C.L.R., at p. 687. C.L.R. 1, at p. 41. (3) (1937) 56 C.L.R., at pp. 701, 702.

HIGH COURT [1942. these powers :—(a) They must not be exercised to pass laws which are repugnant to applicable Imperial laws: See Colonial Laws Validity Act 1865, sec. 2. (b) Some powers (Constitution, sec. 107) which State Parliaments would otherwise possess have been exclu- sively vested in the Parliament of the Commonwealth (see, e.g., secs. 52, 90) or withdrawn from the Parliaments of the States (see, e.g., such prohibitions as are contained in secs. 92, 114, 115, 117). (c) Laws of the State which are inconsistent with laws of the Com- monwealth are invalid to the extent of the inconsistency (sec. 109). Thus if both the Commonwealth Parliament and the State Parlia- ments have power to pass a law with respect to a certain subject —e.g., bankruptcy—the Commonwealth law prevails in the event of inconsistency. The powers of the States are, it is true, " plenary within their limits," but those limits may be determined in many matters by Commonwealth laws which may make State laws invalid. The Commonwealth Parliament is limited in its legislation by the grants of power made by the Constitution and by the prohibitions contained in the Constitution, as well as by the Colonial Laws Validity Act, (the Statute of Westminster 1931 not having been adopted by the Commonwealth). But no law which is within a Commonwealth power can be rendered invalid by any State law, though a State law which, apart from action by the Commonwealth Parliament, would be valid, may be invalid by reason of inconsistent provisions ina Commonwealth law (sec. 109). In this case the plaintiffs do not rely on any express provision in the Commonwealth Constitution for the purpose of showing that the aa Act and the Grants Act, as well as the other Acts considered together with them, are invalid. They rely upon the alleged implied prohibition as to non-interference by the Commonwealth with State constitutional functions, capacities or activities. They point to secs. 106 and 107 of the Constitution, which have already been quoted. These sections, however, do not confer any powers upon a State or upon a State Parliament. They preserve existing powers, but, as to State Constitutions (sec. 106) "subject to the" (Com- monwealth) "Constitution," and, as to State legislative powers, (sec. 107) only after withdrawals and exclusions effected by the Con- stitution, and then subject to the effect of overriding Commonwealth laws where the Commonwealth Parliament has power to legislate (sec. 109). These provisions cannot be relied upon to limit by either express or implied prohibition any provision conferring powers upon the Commonwealth. They do make it clear that the Common- wealth possesses only the powers granted by the Constitution. 65 C.L.R.] OF AUSTRALIA. But they do not limit the sphere or restrict the operation of the H- ©. or A. powers which are so granted. The Engineers' Case (1) did not deny the existence of implied powers or prohibitions (see the report (2)). Should then the particular implication for which the plaintiffs contend be made upon some ground other than the express terms of secs. 106 and 107 of the Constitution ? In the first place it may be admitted that revenue is essential to the existence of any organized State, and that there cannot be either reliable or sufficient revenue without power of taxation. The power of taxation may fairly be said to be an essential function of a State. But this admission states a universal opinion. There is no universal or even general opinion as to what are the essential functions, capacities, powers, or activities of a State. Some would limit them to the administration of justice and police and necessary associated activities. There are those who object to State action in relation to health, education, and the development of natural resources. On the other hand, many would regard the provision of social services as an essential function of government. When Lord Watson said in Coomber v. Justices of Berks (3) that " the administration of justice, the maintenance of order, and the repres- sion of crime are among the primary and inalienable functions of a constitutional government," he was not purporting to give an exhaustive definition of the functions of government. In a fully self-governing country where a parliament determines legislative policy and an executive government carries it out, any activity may become a function of government if parliament so determines. It is not for a court to impose upon any parliament any political doctrine as to what are and what are not functions of government, or to attempt the impossible task of distinguishing, within functions of government, between essential and non-essential or between normal or abnormal. There is no sure basis for such a distinction. Only the firm establishment of some political doctrine as an obligatory dogma could bring about certainty in such a sphere, and Australia has not come to that. Thus the principle for which the plaintiffs contend must be applied, if at all, in protection of all that a State chooses to do, and it must mean that Commonwealth legislation cannot be directed to weaken or destroy any State function or activity whatsoever. But it cannot be denied that Commonwealth legislation may be valid though it does in fact weaken or destroy, and even is intended (1) (1920) 28 C.L.R. 129. (2) (1920) 28 C.L.R. 129, at p. 155.

HIGH COURT [1942. to weaken or destroy, some State activity. Sec. 109 shows that this must be so in many cases. Commonwealth laws have in fact put an end to the existence of State Courts of Bankruptcy and State Patent, Trade Mark and Copyright Departments. The Common- wealth laws are not invalid on that account. They have produced the results stated just because they are valid. It is true that the Commonwealth Parliament has no power to make laws with respect to the capacity and functions of a State Parliament. It has already been stated that the Commonwealth Parliament could not pass a law to prohibit a State Parliament from lepislating in general or from legislating upon some particular subject matter. But this limit upon the power of the Commonwealth Parliament does not arise from any prohibition or limitation to be implied from the Constitution. It is simply the result of the absence of power in the Commonwealth Parliament to pass laws with respect to the functions or powers of State Parliaments. The Commonwealth Parliament cannot legislate with respect to any subject whatever unless a power to do so is conferred on it by the Constitution. No power such as that mentioned is given by the Constitution to the Parliament. But the Acts in question are not laws with respect to State functions. They do not command or prohibit any action by the State or by the State Parliament. Indirect Effects of Laws.—A law may produce an effect in relation to a subject matter without being a law with respect to that subject matter. Questions of motive and object are irrelevant to the question of the true nature of a law. The nature (or " substance " if that word is preferred) of a law is to be determined by what it does, not by the effect in relation to other matters of what the law does. A prohibition of import or a very high duty in a customs tariff may bring about the closing of business enterprises in a State. But the tariff is not a law with respect to those enterprises. Similarly a State law may prohibit the carrying on of occupations with the result that they are necessarily abandoned, with perhaps great consequential loss to the Commonwealth in customs duties or income-tax receipts. But the State law does not for this reason become a law with respect to customs duties or income tax. The true nature of a law is to be ascertained by examining its terms and, speaking generally, ascer- taining what it does in relation to duties, rights or powers which it creates, abolishes or regulates. The question may be put in these terms: '" What does the law do in the way of changing or creating or destroying duties or rights or powers?" The consequential effects are irrelevant for this purpose. Even though an indirect 65 C.L.R.] OF AUSTRALIA. consequence of an Act, which consequence could not be directly achieved by the legislature, is contemplated and desired by Parlia- ment, that fact is not relevant to the validity of the Act (R. v. Barger (1) ; Osborne v. The Commonwealth (2) ; Attorney-General for Queensland v. Attorney-General for the Commonwealth (3) ; Sonzinsky v. United States (4), and see note in the Lawyers' Edition (5) ). This principle should be remembered when it is said that a Parlia- ment of limited powers cannot do indirectly what it cannot do directly. This proposition is of value when (as has not infrequently happened in Canada) it is contended that an Act is colourable in character in that, under the guise or pretence of doing something permitted, it is in reality doing something prohibited or beyond power. The relevant Canadian cases generally deal with the diffi- culties arising from the grant of exclusive powers to both Dominion and Provinces. The emphasis placed upon this point may be noted in John Deere Plow Co. Ltd. v. Wharton (6); Great West Saddlery Co. v. The King (7); Attorney-General for Ontario v. Reciprocal Insurers (8). When the areas of such competing powers overlap, and the challenged law is, for example, both a law relating to insur- ance (Provincial power) and to crime (Dominion power), a court must make a choice as to the category to which the law should be assigned: See, e.g., Attorney-General for Ontario v. Reciprocal Insurers (9) ; In re Insurance Act of Canada (10), where the decision against the Dominion was assisted by the fact that the Dominion Parliament has sought to give itself power by a palpably " false definition ""—a provision that a company should be deemed to "immigrate '"' into Canada if it sent to Canada a document appoint- ing an agent there: see the report (11). Upon this difficult question the Privy Council has ultimately decided to abstain from laying down any general principle, leaving the question of ultra vires to "be determined in each case as it arises, for no general test applicable 'to all cases can safely be laid down" (Attorney-General for Alberta v. Attorney-General for Canada (12) ). The Commonwealth Constitu- tion does not confer any exclusive powers upon the States. Subject to the Constitution the States are left with powers not given exclu- sively to the Commonwealth or withdrawn from the States (secs. 106, 107). Sec. 109 then gives to any Commonwealth law, whether - (1) (1908) 6 C.L.B. 41, at pp. 66, 67. (6) (1915) A.C. 330, at pp. 337, 338, (2) (1911) 12 C.L.R. 321, at p. 335.

Qe Sourn AUSTRALIA v. THE ComMon- WEALTH. Latham C.J. HIGH COURT [1942. made under an exclusive or under a concurrent power, overriding operation over any State law. Thus the difficulties of choosing between two heads of power, stated to be exclusive, but in fact overlapping, do not arise in Australia. The problem, as explained in the Hngineers' Case (1), is the different, though not always easy, problem of deciding whether a particular Commonwealth law falls within a head of Commonwealth power: if it does, it is immaterial that the States may also have power to legislate on the matter. If the law falls within the Com- monwealth power, the law is valid and fully operative, notwith- standing any State law. Barger's Case (2) is an illustration of the difficulty of deciding whether a particular law really does fall within a granted power, but, as already pointed out, Barger's Case (2) in all the judgments rejects considerations of indirect consequences as being irrelevant material. If the validity of a State law is in question, the Court has to decide whether the law is a law for the peace, order and good government of a State: if not (as if it purported to prohibit the Commonwealth Parliament from exercising its powers) it is invalid because beyond State power. If not beyond State power for this reason, it may be repugnant to applicable Imperial law (Colonial Laws Validity Act 1865, sec. 2) or trench upon Commonwealth exclusive power, or be opposed to a prohibition in the Constitution (e.g., secs. 92, 114), or be inconsistent with a valid Federal law (sec. 109). In any of these cases it is invalid. In none of the instances mentioned can any consideration of indirect consequences be relevant. When a power is defined by reference to purpose, other considera- tions arise (Deputy Federal Commissioner of Taxation (N.S.W.) v. W. R. Moran Pty. Ltd. (3)). So also if there were a prohibition against attaining a result by any method whatever. If, for example, the Commonwealth Constitution contained a provision that no Commonwealth law should by any means bring about the result of a discrimination between States, the indirect consequential effects of the law would have to be examined. But the Constitution con- tains no such provision. For example, taxation laws may not discriminate between States (sec. 51 (ii.) ); laws of trade; commerce or revenue may not give preference to a State (sec. 99). These provisions affect only laws of the stated character. Thus there may be discrimination between States and preferences to States under sec. 96—grants to States—because that section is not subject to any limitation with respect to discrimination (Deputy Federal (1) (1920) 28 C.L.R. 129. (3) (1939) 61 C.L.R. 735, at pp. 759, (2) (1908) 6 C.L.R. 41. 760. 65 C.L.R.] OF AUSTRALIA. Commissioner of Taxation (N.S.W.) v. W. R. Moran Pty. Ltd. (1)). ©. oF A Thus, although the Commonwealth Parliament cannot validly pass laws limiting the functions of State Parliaments—and vice versa—the Tax Act and the Grants Act are not invalid on that ground. They do not give any command or impose any prohibition with respect to the exercise of any State power, legislative or other. The Tax Act simply imposes Commonwealth taxation, and is authorized by sec. 51 (ii.) of the Constitution. The Grants Act authorizes payments to States which choose to abstain from imposing income tax, and is valid by reason of sec. 96 of the Constitution, unless it is bad as involving some prohibited discrimination or preference. It is now necessary to deal specifically with that objection. Discrimination.—Sec.'96 provides that: " During a period of ten years after the establishment of the Commonwealth and thereafter until the Parliament otherwise provides, the Parliament may grant financial assistance to any State on such terms and conditions as the Parliament thinks fit." Plainly under this provision financial assis- tance could be given to a single State only. Thus variation in amounts given to different States is permissible. The section contains no express or implied prohibition against any kind of discrimination : See references to Moran's Case (1). Thus it is no objection to the Grants Act that States which abandon income tax are given a grant while those who retain income tax get nothing. So also the indirect effect of varying grants upon the fortunes of taxpayers of different States is an irrelevant circumstance. The Tax Act itself is a general Act, applying to all. persons in all States without discrimination. The States, not the taxpayers, receive varying amounts under the Grants Act. As taxpayers in some States will this year pay more in Commonwealth income tax than they did last year in both Commonwealth and State income tax, and taxpayers in other States will pay less than last year, it is said that the Tax Act, read with the Grants Act, discriminates between States. But a comparison of this year with last year or any past year is not to the point. If the Commonwealth had not enacted the challenged Acts, no-one can say what the Commonwealth or State rates of tax would have been this year. The question whether these facts unlawfully discriminate between States cannot be answered by any consideration of the actual position of taxpayers under past legislation (which was alterable by one Commonwealth and six State Parliaments severally) or by a speculation as to the (1) (1939) 61 C.LR., at pp. 762 et seq. ; (1940) A.C. 838, at pp. 857, 858; 63 C.L.R. 338, at pp. 348, 349. 1942, Sy Souter AUSTRALIA wv THE Common- WEALTH.

HIGH COURT [1942. taxation which would probably have been imposed by Common- wealth and States if the Acts in question had not been passed. Further, as already pointed out, the proceeds of the Tax Act simply go into general consolidated revenue, together with the receipts from other taxes and other moneys, such as the revenue derived from the post office. Then a portion of this general fund is applied, to the extent of £33,489,000, in making grants to States, if the States are willing to accept them. There is no reduction of Commonwealth income tax to taxpayers in particular States. It is true that in Moran v. Deputy Commissioner of Taaation (1) the Privy Council pronounced a warning that possibly (no decision was given on the question) a grant under sec. 96 might be used for the purpose of effecting discrimination in regard to taxation— "under the guise or pretence of assisting a State with money." It may be that, with a very misguided Parliament, such a case is perhaps conceivable. If the proceeds of a tax could be earmarked and if such proceeds were then distributed in whole or in part among the States upon a discriminatory basis the case apparently contemplated by the Privy Council would arise. Reference has however already been made to the difficulties which, under the Commonwealth Constitution, stand in the way of earmarking Commonwealth revenue in any respect. In the Hoosac Mulls Case (2) the Supreme Court of the United States considered such a case as that suggested. The Agricultural Adjustment Act was there held invalid because the proceeds of a tax were identified with a purpose to which the Act was applied, that purpose being held to be an unlawful purpose. It was held to be unlawful because it involved an invasion by the Federal Government of the reserved powers of the States (3). This decision depended upon the doctrine of immunity of State instru- mentalities which, in Australia, was rejected in the Engineers' Case (4)—See the discussion of this case in The Supreme Court and the National Will by Dean Alfange, pp. 180 et seq. If the proceeds of a Commonwealth tax were as such devoted to some unlawful purpose, the case contemplated by the Privy Council might arise and it would be similar to the Hoosac Mills Case (2). But it will not be easy to find a case where it can properly be held that an appropriation Act making grants to States is invalid because it involves an infringement of the provision that Acts with respect to taxation shall not dis- criminate hetween States or parts of States.

Tt imposes the same tax at the same rates upon all persons in all States throughout Australia. It does not make any discrimination whatever between States—it does not even refer to any State. The Act is also a law of revenue, and therefore must not give prefer- ence to any State (sec. 99). The Act does not give preference to any State. The Grants Act is an Act dealing with expenditure— an appropriation Act. It does draw distinctions between States. There is no constitutional reason why it should not do so. There never has been and there cannot be uniformity in payments made by the Commonwealth in or to States or persons in States. Dis- crimination in expenditure between States is found in every Common- wealth budget and in many appropriation Acts. It has never been argued either that such differentiation should be avoided or that it could be avoided. Conclusion as to Tax Act and Grants Act.—Thus the objections to the Tax Act and the Grants Act fail, whether those Acts are considered separately or as part of a scheme to bring about the abandonment by the States of the raising of revenue by taxation of incomes. It is perhaps not out of place to point out that the scheme which the Commonwealth has applied to income tax of imposing rates so high as practically to exclude State taxation could be applied to other taxes so as to make the States almost completely dependent, financially and therefore generally, upon the Commonwealth. If the Common- wealth Parliament, in a grants Act, simply provided for the payment of moneys to States, without attaching any conditions whatever, none of the legislation could be challenged by any of the arguments submitted to the Court in these cases. The amount of the grants could be determined in fact by the satisfaction of the Common- wealth with the policies, legislative or other, of the respective States, no reference being made to such matters in any Common- wealth statute. Thus, if the Commonwealth Parliament were prepared to pass such legislation, all State powers would be controlled by the Commonwealth—a result which would mean the end of the political independence of the States. Such a result cannot be prevented by any legal decision. The determination of the propriety of any such policy must rest with the Commonwealth Parliament and ultimately with the people. The remedy for alleged abuse of power or for the use of power to promote what are thought to be improper objects is to be found in the political arena and not in the Courts. Income Tax (War-time Arrangements) Act 1942.—The provisions of this Act have already been stated. Under this Act, if it is valid, 1942, Sy Souru AUSTRALIA wY THE Common- WEALTH. Latham C.J. H. ©. or A. 1942, SH South AUSTRALIA vw. THE Common- WEALTH. Latham 0.J. HIGH COURT [1942. the Commonwealth can, during the war, and a stated period there- after, take over all the personnel, present or future, of any State income tax department, with its office accommodation, present or future, and office equipment, present or future. Thus the operation of the Act would make the existence of such a department impossible. Compensation for the possession and use of office accommodation, furniture and equipment is to be determined, in default of agree- ment, by an arbitrator appointed by the Governor-General (sec. 11 (3)). No provision is made for compensation in respect of returns and records (sec. 13). The Commonwealth Parliament has power to make laws with respect to the acquisition of property on just terms from any State or person for any purpose in respect of which the Parliament has power to make laws (Constitution, sec. 51 (xxxi.) ). If this is the only power of the Parliament to legislate for the acquisition of property, it may be questioned whether the determination of compensation by an arbitrator appointed by the acquiring Commonwealth satisfies the requirement of just terms. The taking over of all returns and records, even with a right of access by the States (which is provided for by sec. 13), but without any compensation, might well be held not to be "on just terms." These questions, however, were not argued. Commonwealth and State income taxes have been collected by a single staff in each State under agreements made between the Commonwealth and the States under the Commonwealth Income Tax Collection Act 1923-1940. The taxes have been collected by the Commonwealth in Western Australia, and in the other States by the States. The actual agreements are not before the Court. Sec. 12 of the War-time Arrangements Act provides that the agreements shall, notwithstanding any provisions contained in them, be suspended as from a date fixed by proclamation until the Act ceases to operate. No argument was heard as to the power of the Commonwealth Parliament to suspend these agreements. Probably they are political arrangements not creating legal obligations between the parties and are terminable at the will of either party. The effect of the applica- tion of the War-time Arrangements Act would be that the same staff or some of the same staff would continue to do the same work as if the Act had not been passed, but under Commonwealth control in all States instead of only in Western Australia, Any saving of manpower brought about by the simplification resulting from the abolition of future State income tax could be effected whether or not the War-time Arrangements Act was applied. It is conceded that, under a general legislative provision, such as the Defence Act or reg. 4 of Statutory Rule No. 77 of 1942 (regulations 65 C.L.R.] OF AUSTRALIA. under the National Security Act 1939-1940), the Commonwealth can H. ©. or A. in time of war, compel the services of any person (including State public servants) for any purpose connected with the defence of the country. But it is a different thing to select a particular class of persons as such and to compel their services only. For example, though under a defence Act the Commonwealth Government can call up citizens for service in the military forces, it would be quite a different thing to pass a law imposing liability to service upon the residents of certain specified States only. Such a law would be prohibited by sec. 117 of the Constitution, which provides that: "A subject of the Queen, resident in any State, shall not be subject in any other State to any disability or discrimination which would not be equally applicable to him if he were a subject of the Queen resident in such other State." So also the Commonwealth can and does compel the services of citizens in the army irrespective of their religious beliefs. But it could not legislate to apply compulsion only to persons who professed @ particular religion (sec. 116). Thus there is a very real difference between general legislation and legislation limited to a particular class. Apart from the defence power it would hardly be argued that the Commonwealth could, as it were, forcibly seize a State department, its personnel, accommodation and equipment, under a law specifically directed to this object. The reason for the invalidity of such a law would be that it was a law with respect to a State department—a matter not within Commonwealth legislative powers. The Common- wealth can, whenever it chooses, establish its own income tax department. The Commonwealth can hire employees even if they belong to a State service, it can take property even if it belongs to a State: but to do these things under general legislation is a very different thing from completely and specifically hquidating a State department and preventing it from being re-established. There is no Commonwealth power to legislate upon such a matter—unless the defence power (sec. 51 (vi.) ) can be called in aid. The defence power was widely interpreted and applied in Farey vy. Burvett (1). But that case shows that even this power has a limit—it is not sufficient to wave the flag as if that were a conclusive argument. The defence power itself is subject to the Constitution (sec. 51, introductory words). Both the extent of the power and the limitation to which it is subject appear from what was said in Farey v. Burvett (1). Griffith C.J. said: "One test, however, must always be applied, namely: Can the measure in question (1) (1916) 21 C.L.R. 433. 1942. — Sourn AUSTRALIA v THE Common- WEALTH. Latham C.J. H. C. or A. 1942, ee) Sourn AUSTRALIA v THE Common- WEALTH. Latham ©.J, HIGH COURT (1942. conduce to the efficiency of the forces of the Empire, or is the connec- tion of cause and effect between the measure and the desired efficiency so remote that the one cannot reasonably be regarded as affecting the other?" (1). Barton J. said that if the particular provision was capable of assisting in defence, that was enough (2). Isaacs J. said : "Tf the measure questioned may conceivably in such circumstances even incidentally aid the effectuation of the power of defence, the Court must hold its hand and leave the rest to the judgment and wisdom and discretion of the Parliament and the Executive it controls—for they alone have the information, the knowledge, and the experience and also, by the Constitution, the authority to judge of the situation and lead the nation to the desired end" (3). So, also, per Higgins J.: " It is not for this Court to decide that the Act does aid defence, or how it aids defence; it is enough that it is capable of being an Act to aid defence, enough that the statement of Parliament is not necessarily untrue " (4). Unless there is to be no definition whatever of defence, so that the defence power is absolutely unlimited, there could be no wider definition or description than in the passages quoted. But the Commonwealth can support legislation under the power only if it can satisfy a court that there is some connection between the legislation in question and the defence of the country. What connection is here suggested ? The preamble to the Act states that with a view to the public safety and defence of the Commonwealth and of the States and for the more effectual prosecu- tion of the war it is necessary and convenient to make the provisions contained in the Act. The Court should treat this expression of the view of Parliament with respect. In a doubtful case it might turn the scale, the presumption being in favour of the validity of Acts rather than of invalidity. But such a declaration cannot be regarded as conclusive. A Parliament of limited powers cannot arrogate a power to itself by attaching a label to a statute. Similar considera- tions apply to the provisions contained in secs. 4 and 11 that the Treasurer may use powers under the Act if in his opinion it is neces- sary for the defence of the Commonwealth &c. to do so. It is contended for the Commonwealth that a single system of Commonwealth income tax in substitution for the twenty-three income taxes now operating (six of which, it may be observed, are Commonwealth taxes) will improve general efficiency by simplifying income-tax administration and by making less onerous the duties of citizens in making returns, and so releasing manpower at a time (1) (1916) 21 C.L.R., at p. 441.

But the War-time H. ©. oF A. Arrangements Act has no relation to these objectives. The attain- ment of them depends upon the effect of the Taw Act and the Grants Act in establishing a single system of income taxation. If, as is expected, the uniform system reduces the work to be done by civil servants, accountants and clerks in relation to income tax, the Commonwealth will have at its disposal under other legislation the services of any persons whom it chooses to call up. The saving of the unnecessary and useless work will be exactly the same whether or not the Commonwealth takes over the State departments, the Commonwealth itself determining in either case what work is unnecessary or useless. : The only other argument used to show a connection between this Act and defence was the suggestion that the Commonwealth could organize and administer an income tax department more efficiently than the States, and that superior Commonwealth management would prevent waste of manpower. This proposition cannot be assumed—and it has not been proved. Further, such an argument would justify the Commonwealth in taking over any State depart- ment whatever under the defence power upon the plea that Common- wealth management was always more efficient than State manage- ment. The Court cannot base any decision upon an assumption so obviously disputable. My conclusion, therefore, is that Act No. 21, the Income Tax (War-time Arrangements) Act 1942 is invalid, because it is beyond the powers of the Commonwealth Parliament. Income Tax Assessment Act 1942, sec. 31.—The provision in this Act which is attacked by the plaintiffs is sec. 31, which inserts a new sec. 221 in the principal Act. Sub-sec. 1, par. a, is as follows : — or the better securing to the Commonwealth of the revenue required for the efficient prosecution of the present war—(a) a tax- payer shall not pay any tax imposed by or under any State Act on the income of any year of income in respect of which tax is imposed by or under any Act with which this Act is incorporated until he has paid that last-mentioned tax or has received from the Commis- sioner a certificate notifying him that the tax is no longer payable." Par. b gives effect to Commonwealth priority in payment of income tax in bankruptcy and in the liquidation of a company, and provides a penalty for infringement of the section of one hundred pounds or six months' imprisonment or both, together with payment of up to double the amount of tax due. Sub-sec. 2 prescribes the duration of the Act as in the case of the Grants Act, sec. 16. 1942, — Sourn AUSTRALIA Oe THE Common- WEALTH. Latham C.J. 434. H. ©: or A. 1942. Se Sourn AUSTRALIA v. THE Common- WEALTH. Latham C.J. HIGH COURT [1942. Two objections are raised by the plaintifis to this provision. First, it is contended that the Commonwealth Parliament has no power to give priority to the obligation to pay Commonwealth income tax over a lawful obligation to pay State income tax. Secondly, it is contended that, upon its true construction, this section does more than give priority. It is argued that it prevents any payment whatever of any future State income tax as long as the section is in operation. The first objection cannot be supported. It is true that Dizon J. in Federal Commissioner of Taxation v. Official Liquidator of E. O. Farley Ltd. (1) and Evatt J. in West v. Commissioner of Taxation (N.S.W.) (2) expressed opinions which may be called in aid of the view that the Commonwealth cannot, by a law passed under the taxation power, give itself priority over the States. But the weight of authority is to the contrary effect: The Commonwealth v. State of Queensland (3) (per Isaacs and Rich JJ. (4); per Higgins J. (5) ; per Gavan Duffy and Starke JJ. (6)); R. v. The Commonwealth Court of Conciliation and Arbitration (7) (per Isaacs J. (8); and per Gavan Duffy, Rich and Starke JJ. (9) ); West v. Commissioner of Taaation (N.S.W.) (10) (per Latham C.J. (11); per Rich J. (12); per Starke J. (13)); and per Evatt J. in Federal Commissioner of Taxation v. Official Liquidator of E. O. Farley Ltd. (14). Apart from these authorities the case of In re Silver Brothers Ltd. (15) is really conclusive on the matter. The Parliament of the Dominion of Canada has power to make laws in relation to—" The raising of money by any mode or system of taxation" (British North Ameria Act 1867, sec. 91 (3)). Apart from the power to make laws with respect to bankruptcy (see the report (16)) the Privy Council held that a provision was valid which made the liability for a Dominion war revenue tax a first charge upon the assets of the tax- payer, and also enacted that such liability should rank for payment in priority to all other claims of whatsoever kind with a certain exception. It was said: "The two taxations, Dominion and Pro- vincial, can stand side by side without interfering with each other, but as soon as you come to the concomitant privileges of absolute priority they cannot stand side by side and must clash ; consequently (1) (1940) 63 C.L.R. 278, at pp. 316, (9) (1936) 38 C.L.R., at p 580. 317.

C. or A. upon any special. provisions of the Canadian Constitution. It is simply an interpretation of a power to make laws in relation to the subject of taxation. The decision is applicable to the Common- wealth Constitution. Thus the Commonwealth has power, by a properly framed law, to make Commonwealth taxation effective by giving priority to the liability to pay such taxation over the liability to pay State taxation. Accordingly the first objection fails. The second objection depends upon the precise effect of the words of sec. 31. The defendants contend that they mean only that State income tax in respect of any year shall not be paid until Commonwealth income tax in respect of that year has been paid. The plaintifis contend that, whatever may have been thought to be the effect of the section, it really provides that no State income tax can be paid for any year until Commonwealth income tax for that year and for future years has been paid. This result follows, it is said, from the fact that the Tax Act imposes tax on all future years of income (Tax Act, secs. 4, 7 (2) ). Sec. 31 provides that a taxpayer shall not pay State tax until he has paid some other Commonwealth tax. The State tax is described in the following words: "any tax imposed by or under any State Act on the income of any year of income in respect of which tax is imposed by or under any Act with which this Act is incorporated." The Tax Act is an Act with which the Assessment Act is incorporated (Lax Act, sec. 3). The Commonwealth tax which under penalty must be paid before the State tax, is " that last-mentioned tax," ie., "a tax imposed by or under any Act with which this Act" (the Assessment Act) "is incorporated "'—i.e., by the Tax Act. The plaintiffs argue that as the Taw Act imposes tax for all future years, no State income tax can be paid on the income of any year until all future Commonwealth income taxes have been paid. Such an interpretation of the section should not be adopted unless no other interpretation is reasonably open. It is possible to construe the words " that last-mentioned tax " as referring only to Common- wealth tax upon the year of income previously mentioned. This construction produces a reasonable result and preserves the validity of the section. It should therefore be adopted. In my opinion the declarations sought that the Tax Act, the Grants Act and sec. 31 of the Assessment Act are invalid should not be made but a declaration should be made that the War-time Arrange- ments Act is invalid, and an injunction limited to that Act should be (1) (1982) A.C., at p. 521. 1942.

The result therefore is that the actions should be dismissed. There will be no order as to costs. Ricu J. I have had the privilege and advantage of reading the reasons which have been prepared by the Chief Justice. As I am in agreement with his Honour on all points but one, and substantially in agreement with his reasons save those concerned with the excepted point, no advantage, but rather disadvantage, would be produced by my publishing separately the reasons which have led me to arrive at the conclusions upon which we are in agreement. I confine myself, therefore, to stating my reasons for coming to the conclusion upon which I have the misfortune to disagree with the learned Chief Justice. I agree with the view that the declarations sought that what have been described as the Tax Act, the Grants Act, and sec. 31 of the Assessment Act are invalid should not be made. I am of opinion, however, that the application for a declaration that the War-time Arrangements Act is invalid should also fail. The argument relating to this Act has centred chiefly upon the provisions of sec. 4. This provides, in effect, that the Treasurer may, at any time and from time to time, by notice addressed to the Treasurer of any State, cause any officers of the State service specified in the notice, who have been engaged in duties which, in the opinion of the Treasurer, are connected with the assessment or collection of taxes upon incomes, to be temporarily transferred to the Public Service of the Commonwealth. The Treasurer's powers in this respect are limited as to time by sec. 16, which provides that the Act shall continue in operation until the last day of the first financial year to commence after the date on which His Majesty ceases to be engaged in the present war, and no longer; and the temporary quality of the transfer is defined by sec. 5, which provides that, unless sooner retransferred, every transferred officer shall be retransferred to the State service immediately after the Act ceases to operate. The authority of the Parliament to entrust to the Treasurer the limited power contained in sec. 4 cannot be disputed (Hodge v. The Queen (1); In re The Initiative and Referendum Act (2) ; British Coal Corporation vy. The King (3); Lloyd v. Wallach (A) ). The Act is expressed to be a war measure, created for the defence of the (1) (1883) 9 App. Cas. 117, at p. 132. (3) (1935) A.C. 500, at p. 519. (2) (1919) A.C. 935, at p. 945.

The scope of the defence power was discussed by this Court in Farey v. Burvett (1), where Isaacs J., as he then was, in a passage which I quoted in Andrews v. Howell (2), said that in considering whether a measure is supportable as an exercise of the defence power "if the measure questioned may conceivably in such circumstances even incidentally aid the effectuation of the power of defence, the Court must hold its hand and leave the rest to the judg- ment and wisdom and discretion of the Parliament and the Executive it controls—for they alone have the information, the knowledge, and the experience and also, by the Constitution, the authority to judge of the situation and lead the nation to the desired end" (3). Applying this test, and the test laid down by the other members of the Bench in that case, I am unable to see anything in sec. 4, whether it be read alone, or in relation to the rest of the provisions of the Act in which it occurs, or in relation to the group of statutes with which that Act is associated, which justifies the conclusion that it is a colourable and not a real exercise by Parliament of the defence power. It is notoriously essential, for the effective prosecution of such a war as is now being waged, a war in which the continued existence of the Commonwealth and its constituent States is at stake, that the whole resources of the nation, whether of men or of things, should be marshalled and concentrated upon war effort. If the Commonwealth is to wage war effectively, it must command the sinews of war. The taxing of income is an important source from which the funds required for war purposes may be drawn; and the other Acts which have been brought in question show that the Commonwealth Parliament was determined to make unusually large drafts upon this source. In these circumstances, I see nothing sinister in a provision which enables the Commonwealth to take over from the State service and place under its own exclusive control for the period of the war, such of the officers employed in that service as it may specify, if those officers have been engaged on duties con- nected with the assessment or collection of taxes upon income, and are therefore, presumably, specially qualified to assist the Common- wealth by performing this essential service. Nor, if the section be read with an unjaundiced eye, do I see anything sinister, or anything suggesting that the section is intended to be used colourably and for the purpose of destroying each and every new State income tax office as and when it may be created, in the provision that the power may be exercised at any time and from time to time (although only during (1).

For aught I know, the view may be taken that State offices are overmanned, and therefore in all or some cases it may be proposed to specify in the first instance some only of the officers now employed in the State income tax offices, and to specify others afterwards if more are found necessary. Indeed, a military calamity, involving the destruction of a transferred building with its personnel, might make it necessary for the Commonwealth, in the interests of the war effort, to acquire the expert services even of a newly created office and specified members of a new staff which a State had brought into existence for its own civil purposes. However this may be, I am of opinion that the powers conferred by sec. 4 are capable of being used for necessary purposes incidental to the defence of the Commonwealth. If at any time an attempt should be made to use them for what is suggested to be some other and unjustifiable purpose, the validity of the suggestion can be determined in proceedings to frustrate the attempt. It is unneces- sary in order to dispose of the present matter to determine whether it would be competent for the Commonwealth Parliament, in exercise of the defence power, to exclude the States from a particular field of taxation altogether. For these reasons I am of opinion that there is nothing in, or connected with, the provisions of sec. 4 which either calls for or warrants the conclusion by this Court that its enactment stands outside the defence power, or is a colourable as contrasted with a genuine exercise of that power. As has been pointed out by the Chief Justice, the question whether any of the other provisions of the Act are obnoxious to placitum 51 (xxxi.) of the Constitution has not been argued and in these circumstances it would not be proper to rule upon the matter. For the reasons which I have stated I am of opinion that the motion fails upon all points and that the declarations asked for should not be made or the injunction granted. Srarke J.

The plaintiffs moved for interlocutory injunctions, but were ordered H. ©. or A. to deliver statements of claim, to which the defendants demurred and also pleaded. By consent it was ordered that the case be argued before the Full Court upon the notices of motion for interlocutory injunctions, the pleadings and various affidavits, subject to all proper objections, and on the matter coming on for hearing before the Court the parties agreed that the motions for injunctions should be treated as the trial of the actions and turned into motions for decrees. Actions in the form adopted in these cases have the sanction of decisions of this Court (Attorney-General for N.S.W. v. Brewery Employees Union of N.S.W. (1); The Commonwealth v. Queensland (2); Tasmania v. Victoria (3) ), with which may be compared the decision of the Supreme Court of the United States of America in Massachussetts v. Mellon (4), and the rules collected by Brandeis J. in Ashwander v. Tennessee Valley Authority (5). The Acts were challenged on the ground that they constituted a legislative scheme of taxation, the object and operation whereof was to constitute the Commonwealth the exclusive taxing authority in Australia in respect of income tax, and to prevent the States from exercising their constitutional powers in relation thereto. The Report of a Committee on Uniform Taxation, and also the speech of the Treasurer of the Commonwealth introducing into Parliament the Bills which became the Acts attacked in this case, were tendered in support of this allegation, and also in support of an allegation that the scheme effected discriminatory taxation between the States contrary to the provisions of the Constitution. But they were rejected. The intention, object, or purpose of a legislative body can only be legitimately ascertained from what it has chosen to enact either in express words or by reasonable and necessary intend- ment (Salomon v. Salomon & Co. (6); Assam Railways and Trading Co. v. Commissioners of Inland Revenue (7); W. R. Moran Pty. Ltd. v. Deputy Commissioner of Taxation (8); R. v. West Riding of Yorkshire County Council (9); Sydney Municipal Council v. The Commonwealth (10) ). But the Court is not precluded from looking at the state and operation of the law when the legislation was passed (Macmillan & Co. v.

HIGH COURT (1942. these purposes was used and may be found in the affidavits filed by the parties and in tables comparing the taxation under the Common- wealth legislation with taxation then in force in both the Common- wealth and the States. The States Grants (Income Taa Reimbursement) Act and the Income Tax (War-time Arrangements) Act, and the Income Tax and the Assessment Acts are numbered in sequence, which indicates the order in which the Bills for this legislation were presented to Parlia- ment and passed into law, but nothing turns on this order. It is desirable, I think, to consider each Act separately before considering it together with other Acts as part of a scheme. 1. Lhe Taa and Assessment Acts (No. 23 of 1942 and No. 22 of 1942).—Subject to the provisions of the Constitution, secs. 86-95, the Commonwealth and the States have concurrent taxing power. That power, within the limits of their several jurisdictions, is unlimited in its range both as to the kind of tax, the subject upon which it shall be imposed, and the amount of the tax, but so, in the case of the Commonwealth, as not to discriminate between States or parts of States, and so that the Commonwealth shall not by any law or regulation of revenue give preference to one State or any part thereof over another State or any part thereof (Constitution, secs. 51 (ii.) and 99). The Tax and Assessment Acts do not on their face contravene these provisions of the Constitution. The tax is gradu- ated, rising steeply on the higher rates of income. But the Constitu- tion only prohibits discrimination between the States or parts of States, or giving preference by any law or regulation of revenue to one State or any part thereof over another State or part thereof, and does not require equality of burden: See Moran's Case (1). Next it was contended that the following provision of the Assessment Act is invalid :—" For the better securing to the Commonwealth of the revenue required for the efficient prosecution of the present war—(a) a taxpayer shall not pay any tax imposed by or under any State Act on the income of any year of income in respect of which tax is imposed by or under any Act with which this Act is incorporated until he has paid that last-mentioned tax or has received from the Commissioner a certificate notifying him that the tax is no longer payable" (Act No. 22 of 1942, sec. 31). It was said that the Commonwealth had no power to give itself priority in payment of its income taxes over the taxes of the States. But that conten- tion, despite some dicta to the contrary, is precluded by the decision of this Court in The Commonwealth v. Queensland (2), and by the (1) (1940) A.C., at p. 857; 63 C.LR., at p. 349. (2) (1920) 29 C.L.R. 1. 65 C.L.R.] OF AUSTRALIA. decision of the Judicial Committee in In re Silver Brothers Ltd. ¥. ©. or A. (1). The taxing power gives the Commonwealth authority to make its taxation effective and to secure to it the full benefit thereof. In my opinion, there is no distinction in principle between the Common- wealth giving itself priority in the administration of assets in bank- ruptcy and in giving itself priority in payment of the personal obligations imposed by an income tax. The dicta above referred to may be found in Federal Commissioner of Taxation y. Official Liquidator of E. O. Farley Ltd. (2) and West v. Commissioner of Taxation (N.S.W.) (3), but the contrary view appears to have been expressed by the same justice in Federal Commissioner of Taaation v. Farley (4), and note Graves v. New York (5). It was also contended that sec. 31 prohibits taxpayers from paying to the States any taxation whatever. If that were the proper construction of sec. 31 the Commonwealth would, I think, transcend its authority, but I cannot so construe the section. The tax imposed is for a financial year, that is, for the twelve months beginning on Ist July, but it is in every year assessed upon the year of income preceding the year of tax: See Tax Act, No. 23 of 1942, sec. 7; Assessment Act 1936-1942, secs. 17 and 6; Acts Interpretation Act 1901-1937, sec. 22. But there is nothing in sec. 31 which prohibits or precludes a taxpayer from paying State taxes so soon as his liability for Commonwealth income tax in any financial year has been dis- charged. The section prescribes priority of payment, and it operates to that extent and no further, both in law and in fact. 2. The States Grants (Income Taw Reimbursement) Act 1942 (No. 20 of 1942).—By sec. 96 of the Constitution the Parliament may grant financial assistance to any State on such terms and conditions as the Parliament thinks fit. This section does not prohibit dis- crimination or preference (Victoria v. The Commonwealth (6) ; Deputy Federal Commussioner of Taxation (N.S.W.) v. W. R. Moran Pty. Ltd. (7) ). The States Grants Act in sec. 4 provides: "In every financial year during which this Act is in operation in respect of which the Treasurer is satisfied that a State has not imposed a tax upon incomes, there shall be payable by way of financial assistance to that State the amount set forth in the Schedule." And there are other pro- visions for further assistance which may be found in the Act, but (1) (1932) A.C. 514.

This device could be made effec- tive, as well in time of war as in time of peace, to control State legis- lation, and the administration of State laws, and ultimately to control and supervise all State functions. The danger to the States is obvious enough, but this Court has nothing to do with political policies or remedies ; its sole function is to determine whether the States Grants Act, in its present form, is warranted by the Constitution. The government of Australia is a dual system based upon a separa- tion of organs and of powers. The maintenance of the States and their powers is as much the object of the Constitution as the main- tenance of the Commonwealth and its powers. Therefore it is beyond the power of either to abolish or destroy the other. The limited grant of powers to the Commonwealth cannot be exercised for ends inconsistent with the separate existence and self-govern- ment of the States, nor for ends inconsistent with its limited grants (Rk. v. Barger (1); In re Insurance Act of Canada (2); Attorney- General for Alberta v. Attorney-General for Canada (3) ). The States Grants Act, it is said, leaves the States perfectly free to exercise their constitutional powers, though the exercise by the Commonwealth of its powers of taxation may render the exercise by the States of their powers difficult or impracticable from an economic standpoint, which it is the object of the States Grants Act to relieve: Cf. Massachusetts v. Mellon (4); Steward Machine Co. v. Davis (5). It cannot be doubted that the Commonwealth cannot expressly prohibit the States from exercising their powers of taxation, and that those powers cannot, subject to the provisions of the Constitu- tion, sec. 51 (xxxviii.), be appropriated by the Commonwealth nor abdicated by the States. The question in this case comes back to this: What is the object and operation of the States Grants Act ? It purports in sec. 4 to grant financial assistance to the States, but is it linked up with an object that is beyond the powers of the Com- monwealth, namely, to control the exercise by the States of their powers to impose taxes upon income ? The title of the Act itself is States Grants (Income Tax Reimbursement) Act. The amounts of the grants set forth in the schedule to the Act are, it is admitted in the pleadings, substantially the average of the amounts raised by each State by means of income tax in the financial years of each respective State ended 30th June 1940 and 30th June 1941. Further, the tax imposed under the Federal Act on the lower grades of income (1) (1908) 6 C.L.R. 41. (4) (1923) 262 U.S., at p. 483 [67 Law. (2) (1982) A.C., at p. 52. Ed., at p. 1083]. (3) (1939) A.C. 117. (5) (1937) 301 U.S., at pp. 589, 590 [81 Law. Ed., at pp. 1292, 1293]. 65 C.L.R.] OF AUSTRALIA. is moderate as compared with the tax imposed upon higher grades 1. ©. or A of income. Consequently it was open for the States to exploit this field of taxation, but if they do so the Grants Act deprives them of the financial assistance thereby provided. In my opinion, the object of the Act is not merely to grant financial assistance to the States, but there is linked up in it an object and an end that is inconsistent with the limited grant of power given by sec. 96 to the Commonwealth, namely, making the Commonwealth the sole effective taxing authority in respect of incomes and com- pensating the States for the resulting loss in income tax. The argument that the States Grants Act leaves a free choice to the States, offers them an inducement but deprives them of and interferes with no constitutional power, is specious but unreal. And it does not meet the substance of the States' position that the condition of the Act relates to a matter in respect of which the Commonwealth has no constitutional power whatever, and yet by force of the condition and not as a consequence of the exercise of any power conferred upon the Commonwealth, the grant of assistance to the States is withdrawn unless they comply with its terms. The real object of the condition is that already stated, and it is in my judgment neither contemplated by nor sanctioned by the Constitution, and in par- ticular by sec. 96 thereof. As I have said, all State legislation and functions might ultimately be so controlled and supervised. The possibility of the abuse of a power is not, however, an argument against the existence of a power. But if the extent of the power claimed by the Commonwealth leads to " results which it is impossible to believe . . . the statute contemplated . .-. there is good reason for believing that the construction which leads to such results cannot be the true construction of the statute" (Lhe Queen v. Clarence (1)). A legitimate use of the powers con- tained in sec. 96 may be found in the Road Grants Case (Victoria v. The Commonwealth (2) ), where the Commonwealth and the State of Victoria entered into an agreement, the object of which was to aid the State in the construction and reconstruction of certain roads. Incidentally the making of roads would be an aid to trade and com- merce, and possibly also to defence: See Federal Aid Roads Act 1926 (No. 46 of 1926). No doubt means can be found to give the States financial assistance without crippling them in the exercise of their powers of self-government if the Commonwealth taxation creates economic difficulties for them. But I cannot agree that the provisions of sec. 96 enable the Commonwealth to condition that assistance upon the States abdicating their powers of taxation or, (1) (1888) 22 Q.B.D. 23, at p. 65.

HIGH COURT (1942. which in substance is the same thing, not imposing taxes upon income. In my opinion, it follows that the States Grants (Income Tax Reim- bursement) Act 1942 is not within the power or authority of the Commonwealth Parliament. 3. Income Tax (War-time Arrangements) Act 1942 (No. 21 of 1942). —by this Act officers of the State service who have been engaged on duties connected with the assessment or collection of income tax may be temporarily transferred to the Public Service of the Com- monwealth, and are by force of a notice given pursuant to the Act transferred accordingly. Any officer may be retransferred to the State, which is obliged to reinstate that officer in a position in the State service upon such terms and conditions as are not less favour- able than the terms, conditions, and rights to which he would have been entitled if the Act had not been passed, and his service as a transferred officer were service with the State. And where during the period of his transfer the transferred officer dies or resigns he is deemed to have been retransferred to the State service immediately prior to his death or the acceptance of his resignation, and all rights of pension, payment, and other benefits arising in respect of the officer's service shall be ascertained as if the Act had not been passed and his service as a transferred officer were service with the State. The liability of the transferred officer to contribute to any State fund established for the purpose of providing superannuation or other benefits is continued, but there are provisions for adjustments as between the Commonwealth and the States. Further, notice may be given to the States that the Commonwealth requires the possession and use of their office accommodation, furniture, and equipment specified in the notice, particularly or in general terms, and the Commonwealth then by force of the Act is given possession and exclusive use thereof accordingly. Provision is made for compensa- tion to the State. And where any returns or records relating either wholly or partly to the assessment or collection of any tax imposed upon incomes by the Parliament of the Commonwealth are in the possession of a State those returns and records are from the com- mencement of the Act transferred to the possession of the Common- wealth provided that the States shall have access to, and may copy such returns and records as relate to the assessment or collection of any tax imposed upon incomes by or under any law of that State. The taxation departments of the States, excepting Western Australia, had for some years, by arrangement with the Common- wealth, assessed and collected income tax on behalf of the Common- wealth. Many taxpayers made only one return in which there were two columns, one for particulars for State income-tax purposes, and 65 C.L.R.] OF AUSTRALIA. the other for Commonwealth income-tax purposes. But taxpayers H.C. oF A. with income derived from more than one State sometimes made two or more returns, one to the Commonwealth, the other or others to the States. In the case of Western Australia the Commonwealth by arrangement with the State assessed and collected tax both for itself and the State. But except in the case of Western Australia the returns and records belong, I take it, to the States, and are exceed- ingly valuable, if not essential, for the purpose of collecting, assessing and checking income taxes. It was faintly contended that the Income Taw (War-time Arrange- ments) Act was authorized by the taxation power conferred upon the Commonwealth under the Constitution, but the main argument in support of the Act was based upon the defence power, as was inevitable from the terms of the Act. The preamble recites that it is necessary or convenient to provide for the matter contained in the Act with a view to the public safety and defence of the Common- wealth and States and the more effectual prosecution of the war, and in secs. 4 and 11 the authorities there given are declared to be necessary for the efficient collection of revenue required for the prosecution of the war, for the effective use of manpower, or other- wise for the defence of the Commonwealth. But the defence power is subject to the Constitution just as are the other powers conferred by sec. 51 of the Constitution. The content of the defence power never changes, though war will, no doubt, enlarge the area of its operation (Andrews v. Howell (1) ). But the defence power does not, any more than any other power contained in sec. 51, enable the Commonwealth to abolish or destroy the States. Nor can the Commonwealth exercise that power for ends inconsistent with the existence of the States or the exercise of their powers or their functions as self-governing bodies. The Com- monwealth can marshal the manpower and resources of the Common- wealth for the purposes of war, and it is said that the Income Tax (War-time Arrangements) Act does no more. According to the argument the Act has a " close and substantial," a direct and not an indirect, a proximate and not a remote, relation to defence, and consequently is within the power. But such a standard is only one of degree and in the end becomes a rule of expedience: See Santa Cruz Fruit Packing Co. vy. National Labor Relations Board (2). The Act, as already set forth, takes power to the Commonwealth at its discretion, to transfer to its service, and appropriate to its own purpose, all the officers, accommodation, and records of the (1) (1941) 65 C.L.R. 255, at pp. 272-278.

Starke J. HIGH COURT [1942. States which constitute their departments of income tax. It preserves all the rights of such officers against the States. It enables the Commonwealth at its discretion to retransfer such officers to the States, and, in any case, when the Act ceases to operate the Act retransfers such officers to the States, and compels the States to reinstate the officers on terms not less favourable than they would have been entitled to had the Act not been passed. It also, on the resignation or death of any transferred officers, automatically retransfers them to the States and prescribes that all rights of pension and other benefits arising in respect of an officer's service shall be ascertained as if the Act had not been passed and his service as a transferred officer were service with the State. These powers are wholly inconsistent with the exercise by the States of their powers and of their functions as self-governing bodies. An important department—indeed an essential department—of the Executive Government of the States may be taken from them, and all its officers, accommodation, and records bodily transferred to the Commonwealth. And obligations are imposed upon the States by force of the Act in relation to the officers transferred. The Common- wealth assumes the right to regulate the relation of the States and the transferred officers, and thus to override any provision the States may consider necessary or expedient in the matter. And it may be noted that the income tax departments of the States are not among those departments transferred to the Commonwealth by force of the Constitution, and in respect of which it has exclusive power to legislate (Constitution, secs. 69 and 52 (ii.) ). The Income Tax (War-time Arrangements) Act is beyond the power conferred upon the Commonwealth to make laws for the peace, order and good government of the Commonwealth with respect to defence, or any other power conferred by the Constitution. Perhaps I ought to refer to the Engineers' Case (Amalgamated Society of Engineers v. Adelaide Steamship Co. Ltd.) (1) and to Andrews v. Howell (2), which the Commonwealth relied upon during the argu- ment. Prior to the decision of this Court in the Engineers' Case (1) the doctrine had been propounded of the immunity of the instru- mentalities and agencies of government, both Federal and State, from interference by the other, an immunity based upon a prohibition implied from the structure of the Constitution. The Hngineers' Case (1) overruled this doctrine, which was contrary to the decision of the Judicial Committee in Webb v. Outtrim (3), which had not been applied consistently in this Court, and which was attended with (1) (1920) 28 C.L.R. 129. (2) (1941) 65 C.L.R. 255. (3) (1907) A.C. 81; 4 C.LR. 356. 65 C.L.R.] OF AUSTRALIA. 447. difficulty in the working of the Constitution. The substance of the H- ©: or A. decision is stated in the Engineers' Case (1): '"'The doctrine of "implied prohibition' finds no place where the ordinary principles of construction are applied so as to discover in the actual terms of the instrument their expressed or necessarily implied meaning." The Court did not say that in interpreting the Constitution no implications of any sort should be made, and the passage quoted makes that, I hope, sufficiently clear. Critics however arose ; one of them, however, happily assures us that the decision was inevit- able and a wise one however it was reached: See West v. Commis- sioner of Taxation (N.S.W.) (2). And it is noteworthy that this doctrine of "implied prohibition" seems also recently (1939) to have been abandoned by the Supreme Court of the United States (Graves v. New York (3) ). Some implications are necessary from the structure of the Constitution itself, but it is inevitable also, I should think, that these implications can only be defined by a gradual process of judicial decision. Andrews v. Howell (4) is irrelevant to the matter under review, but it illustrates the wide range of the defence power. 4. Severability.—The invalidity of the States Grants (Income Tax Reimbursement) Act 1942 and the Income Tax (War-time Arrange- ments) Act 1942 does not, however, also render invalid the Income Tax Act 1942 nor the Income Tax Assessment Act 1942. These last-mentioned Acts are in themselves consistent, workable and effective, they deal with a subject matter within the power of the Commonwealth, and are not connected with nor dependent upon the validity of the other Acts as conditions, considerations or compensa- tions. Moreover, the provisions of the Acts Interpretation Act 1901- 1937, sec. 15a, can also be called in aid (Roughley v. New South Wales (5) ; Deputy Federal Commissioner of Taxation (N.S.W.) v. W. R. Moran Pty. Ltd. (6) ). 5. The Acts as part of a scheme-—The Judicial Committee in Moram's Case (7) observed that " where there is admittedly a scheme of proposed legislation, it seems to be necessary when the * pith and substance ' or ' the scope and effect ' of any one of the Acts is under consideration, to treat them together and to see how they interact. The separate parts of a machine have little meaning if examined without reference to the function they will discharge in the machine." It was not disputed, I think, that the object of the Acts was to (1) (1920) 28 C.L.R., at p. 155. (4) (1940) 65 C.L.R. 255.

HIGH COURT [1942. introduce into Australia a uniform income tax having priority over State taxes upon income, paying to the States, which retired from the field of income taxation, compensation substantially equal to the average of the amounts raised by that State by means of income tax in the financial years ended June 1940 and 1941. The States, however, insist that the scheme operates to destroy their constitu- tional powers to raise revenue by way of income tax ; to discriminate in taxation between them; and to give preference by a law or regulation of revenue to those States which vacate the income-tax field over the States that do not vacate that field. But the scheme of legislation is, I think, unimportant unless the legislation is con- nected together and the provisions of the legislative Acts are depen- dent the one upon the other, which is not, as I think, the case here. Assume, however, that the States Grants Act be valid, does it, coupled with the Taxation Acts, discriminate between or prefer one State over another contrary to the provisions of the Constitution? The provisions of the Acts taken together operate, it is said, as a sort of rebate of taxation (Attorney-General for British Columbia v. McDonald Murphy Lumber Co. (1) ) contrary to the provisions of the Constitu- tion. Moran's Case (2) itself supplies an answer to the argument : See the report (3). The grants of assistance, if valid, are for the purpose of compensating the States for the losses they would each sustain from the imposition of uniform taxation and preventing unfairness or injustice to the States. The taxation is applicable in all States and parts of States alike, but the losses sustained by the States by the operation of the Tax Acts are not alike, and are adjusted by the Grants Act. In my judgment, the States Grants (Income Tax Reimbursement) Act 1942 and the Income Tax (War-time Arrangements) Act 1942 should be declared invalid, but otherwise the relief claimed in the several actions should be denied. McTiernan J. The question to be decided is whether four Acts which have been passed by the Commonwealth Parliament are within the powers vested in the Parliament by the Commonwealth of Australia Constitution Act. The Acts are the Income Tax Act 1942, the Income Tax Assessment Act 1942, the States Grants (Income Tax Reimburse- ment) Act 1942 and the Income Tax (War-time Arrangements) Act 1942. In my opinion these Acts are justified by the following provisions of the Constitution: The Income Tax Act and the Income Tax Assessment Act by sec. 51 (ii.), (vi.) and (xxxix.), the States Grants (1) (1930) A.C. 357. (3) (1940) A.C., at pp. 856-858; 63 (2) (1940) A.C. 888: 63 C.L.R. 338. C.LR., at pp. 347-349. 65 C.L.R.] OF AUSTRALIA. Act by sec. 96, sec. 51 (vi.) and (xxxix.), and the War-time Arrange- ments Act by sec. 51 (vi.) and (xxxix.). Sec. 51 of the Constitution provides that the Parliament shall, "subject to this Constitution,' have power to make laws for the peace, order and good government of the Commonwealth of Australia with respect to, among other things, "(ii.) Taxation; but so as not to discriminate between States or parts of States:" "(vi.) The naval and military defence of the Commonwealth and of the several States . . .:" and " (xxxix.) Matters incidental to the execution of any power vested by this Constitution in the Parliament or in the Government of the Commonwealth." Sec. 96 vests in the Parliament power to grant financial assistance to any State on such terms and conditions as the Parliament thinks fit. It is a settled principle of interpretation that the words " subject to this Constitution " mean subject to the provisions of the Con- stitution. They do not make any power vested in the Parliament by this section subject to any a-priord rules for reconciling State and national powers under a Federal system of government. It is also a settled principle that the powers vested in Parliament by the Constitution are, subject only to its provisions, plenary. Lach is not less than a complete power to make laws with respect to the subject of the power. The taxation power includes the power to impose income tax for the purposes of the Commonwealth. The Court assumes that an Act, which in substance imposes taxation, was passed by the Parlia- ment for the purpose of raisimg revenue for the Commonwealth. There is no legal limitation to the amount of the rate of taxation which the Parliament may impose. The nature and extent of the Commonwealth defence power is explained in Farey v. Burvett (1). In that case Griffith C.J. said it "includes all acts of such a kind as may be done in the United Kingdom, either under the authority of Parliament or under the Royal Prerogative, for the purpose of the defence of the realm, except so far as they are prohibited by other provisions of the Con- stitution. . . . It includes preparation for war in time of peace, and any such action in time of war as may conduce to the successful prosecution of the war and defeat of the enemy. This is the constant and invariable meaning of the term. It is obvious, however, that the question whether a particular legislative act is within it may fall to be determined upon very different considerations in time of war. and time of peace. . . .

HIGH COURT (1942. Mann's argument that the power to legislate with respect to defence extends to any law which may tend to the conservation or development of the resources of the Commonwealth so far as they can be directed to success in war, or may tend to distress the enemy or diminish his resources, as, for instance, by the prohibition of trading with him or with persons associated with him. But this definition is not exhaustive. The control of finance or trade may be the most potent weapon of all. One test, however, must always be applied, namely: Can the measure in question conduce to the efficiency of the forces of the Empire, or is the connec- tion of cause and effect between the measure and the desired efficiency so remote that one cannot reasonably be regarded as affecting the other?" (Farey v. Burvett (1), per Griffith C.J.). The Chief Justice added: " The power to make laws with respect to defence is, of course, a paramount power, and if it comes into conflict with any reserved State rights the latter must give way " (2). The nature and extent of the Commonwealth defence power were also explained by Isaacs J., as he then was, in Farey v. Burvett (3). His Honour said that when war imperilling our existence had begun the limits of the defence power "'then are bounded only by the requirements of self-preservation. It is complete in itself, and there can be no implied reservation of any State power to abridge the express grant of a power to the Commonwealth " (4). His Honour added :—"' As I read the Constitution, the Commonwealth, when charged with the duty of defending Commonwealth and States, is armed as a self-governing portion of the British Dominion with a legislative power to do in relation to national defence all that Parlia- ment, as the legislative organ of the nation, may deem advisable to enact, in relation to the defence of Australia as a component part of the Empire, a power which is commensurate with the peril it is designed to encounter, or as that peril may appear to the Parliament itself ; and, if need be, it is a power to command, control, organize and regulate, for the purpose of guarding against that peril, the whole resources of the continent, living and inert, and the activities of every inhabitant of the territory. The problem of national defence is not confined to operations on the battlefield or the deck of a man-of-war; its factors enter into every phase of life, and embrace the co-operation of every individual with all that he possesses —his property, his energy, his life itself ; and, in this supreme crisis, we can no more sever the requirements and efforts of the civil population, whose liberties and possessions are at stake, from the (1) (1916) 21 C.L.R., at pp. 440, 441.

Higgins J. said in the-same case : "" What is the ambit of the power, not merely to make laws for the control of the forces, but to make laws (not for, but), 'with respect to' naval and military defence, and to matters incidental to that power and the powers of the Government ? All the subjects for legislation in sec. 51 are on the same logical level: there is no hierarchy in the powers, with the power as to defence on the top. But, from the nature of defence, the necessity for supreme national effort to preserve national exist- ence, the power to legislate as to defence, although it shows itself on the same level as the other powers, has a deeper tap-root, far greater height of growth, wider branches, and overshadows all the other powers. Defence—naval and military defence—is primarily a matter of force, actual or potential; the whole force of the nation may be required ; and for the purpose of bringing the whole force of the nation to bear, the policy of the States may have to be tem- porarily superseded, the law made under the Federal Constitution prevailing (sec. 109). The temporary suspension of the policy of a State may possibly help to prevent the total and permanent paralysis of the State's policy and functions, and of the State itself, under foreign invasion and domination. In Great Britain there is no limit to the legislative powers, and therefore there is no line of demarcation between Acts for defence and Acts for other purposes " (2). This doctrine as to the nature and extent of the defence power was accepted and applied recently in the case of Andrews v. Howell (3). Sec. 96 does not bind the Parliament to give equal grants to the States. A law granting financial assistance is not a law or a regula- tion of revenue under sec. 99. Sec. 96 leaves to the judgment of Parliament the question of deciding to what State or States it will grant financial assistance, the amount of the grant, and the terms and conditions of the grant. The Income Taw Act 1942 imposes income tax and declares the rates of taxation: See Constitution, secs. 53 and 55. The Income Tax Assessment Act 1942 provides for the assessment and levy of income tax. It is incorporated with the Income Taa Act 1942 by sec. 3 of this Act. Each of these Acts is (apart from sec. 31 of the Assessment Act as to which a special question is raised) in real sub- stance and effect a law with respect to Commonwealth income taxation. Neither law contains any provision which infringes any (1) (1916) 21 C.L.R., at p. 455. (2) (1916) 21 C.L.R., at pp. 457, 458. (8) (1941) 65 C.L.R. 255.

HIGH COURT [1942. restriction imposed by the Constitution. The Acts do not, in the imposition of the tax or in the declaration of the rates of taxation or in any other way, discriminate between the States or parts of States. The power of taxation (customs and excise excepted) is not by the Constitution exclusively invested in the Commonwealth Parliament nor withdrawn from any State. This power continues in the States. But any State law is subject to sec. 109 of the Constitution, which provides that when a law of a State is inconsistent with a law of the Commonwealth, the latter shall prevail and the former shall, to the extent of the inconsistency, be invalid. There is no legal limitation on the amount of the rate of taxation which a State Parliament may impose. These Commonwealth and State powers of taxation have been described as concurrent powers. They are, more strictly, separate powers. A State Act and a Commonwealth Act have not been regarded as inconsistent, merely because each imposes tax on a taxpayer in respect of the same income. But a question of incon- sistency which is resolved by sec. 109 in favour of the Common- wealth arises when the Commonwealth Parliament, by a valid law, commands the taxpayer to pay the Commonwealth tax before he pays the State tax. Sec. 31 of the Income Tax Assessment Act prohibits a taxpayer from paying State tax before he pays Common- wealth tax. A question was raised whether, having regard to sec. 7 (2) of the Income Tax Act 1942, the effect of sec. 31 is to introduce a prohibition against the payment of State income tax. The question turns on the meaning of the words "that last-mentioned tax" in sec. 31. These words, in my opinion, refer to Commonwealth tax for a year of income in contradistinction to the State tax imposed in respect of that year. The meaning of the section is that the taxpayer is forbidden under the penalty of £100 or imprisonment for six months from paying State tax imposed for any year until he has paid the Commonwealth tax due by him for that year. Sec. 31 is preceded by the recital showing that in enacting the section Parliament intended to exert the Commonwealth defence power. The recital is: "For the better securmg . . . of the revenue required for the efficient prosecution of the present war." The operation of the section is expressly limited to a period ending twelve months after the cessation of the war. Sec. 32 of the same Act provides that all the other amendments made by the Act shall con- tinue in force in all subsequent years. The Income Lax (War-time Arrangements) Act is also prefaced by a recital showing that Parliament regarded this Act as a defence measure. The recital is: '" Whereas with a view to the public 65 C.L.R.] OF AUSTRALIA. safety and defence of the Commonwealth and of the several States and for the more effectual prosecution of the war in which His Majesty is engaged, it is necessary or convenient to provide for the matters hereinafter set out." The Court is not bound to declare a law, containing a recital such as either of those which have been quoted, a good law with respect to defence or matters incidental to the execution of the defence power. The position is examinable, but in a limited way. In Farey v. Burvett (1), Griffith C.J. said:—'So far as the attack is made upon the Act as distinct from the Regula- tion the Court is invited to assume the function of determining whether the facts were at the time when the Act was passed such as to warrant the Parliament in exercising the defence power by passing it. Whether it was or was not authorized to do so must, so far as the authority depends upon facts, depend upon the facts as they appeared to it, of which we have not, and cannot have, any knowledge. In my opinion there is no principle, and there is certainly no precedent, which would justify a Court in entering upon such an inquiry, if upon any state of facts the exercise of the legis- lative power in the particular way adopted could be warranted. If it appeared on the face of the Act that it could not be substantially an exercise of the defence power different questions would arise. I am not prepared to say that it may not have some, and some important, influence upon the successful conduct of the war." And in the same case Isaacs J. said: "If the measure questioned may conceivably in such circumstances" (now the circumstances are a war of aggression against the Commonwealth, invasion of parts of its territories, and threatened invasion of the Commonwealth) "even incidentally aid the effectuation of the power of defence, the Court must hold its hand and leave the rest to the judgment and wisdom and discretion of the Parliament and the Executive it controls—for they alone have the information, the knowledge and the experience and also, by the Constitution, the authority to judge of the situation and lead the nation to the desired end" (2). Reverting to sec. 31 of the Income Tax Assessment Act. This section gives the Commonwealth the prior right to a large part of the financial resources of the whole country. It is clearly a law which is incidental to defence, having regard to the present emergency. Parliament has rested the section on the defence power, and it is justified by that power. It is unnecessary then to decide whether the section is within the powers vested in the Parliament by sec. 51 (ii.) and (xxxix.). (1) (1916) 21 C.L.R., at p. 443.

HIGH COURT (1942. The Income Tax Assessment Act denies to the taxpayer substantial deductions allowed by previous Commonwealth Acts, and the Income Tax Act increases the rates of taxation far above the previous rates. The consequence which will be likely to flow from these Acts is that a taxpayer will hardly be able to pay State income tax out of the residue of his income left after he has obeyed the command of sec. 31 to pay Commonwealth tax computed under the Commonwealth Acts. If the States are unable to administer their State taxation Acts, or to freely exercise their powers of taxation, this disability arises from the economic consequences of the Commonwealth Acts. But these economic consequences and the resulting practical disability of the States are irrelevant in deciding the question whether the Commonwealth legislation is within the legislative powers of the Commonwealth. These Acts are in substance and effect laws with respect to Commonwealth taxation and defence and matters incidental to the execution of these powers. ; The States Grants (Income Tax Reimbursement) Act 1942.—This Act and the Income Taw Act were assented to on the same day. It is expressed to begin on Ist July 1942, and to continue until the last day of the first financial year beginning after the end of the war. This Act and the Income Tax Acts will operate simultaneously. The Act describes itself as: " An Act to make provision for the grant of financial assistance to States, and for other purposes." It is con- tended that this Act, which purports to be an execution by the Parliament of the power vested in it by sec. 96, and the Income Tax Acts, are only a colourable exercise by the Parliament of its powers because, as it is alleged, they are interdependent parts of a scheme or total law the substance and effect of which is to collect both Common- wealth and State taxation, to transfer a quota of the revenue collected to the States, and thereby prevent the States from exercising their powers of taxation. In my opinion it is impossible to draw these conclusions from the provisions of these Acts. Sec. 4 of the States Grants (Income Tax Reimbursement) Act provides that in every financial year during which this Act is in operation in respect of which the Commonwealth Treasurer is satisfied that a State has not imposed a tax upon incomes, there shall be payable by way of financial assistance to that State the amount set forth in the schedule against the name of that State. The amount is the average amount raised by that State by means of income tax in the financial years ended 30th June 1940 and 1941, and the amount of tax which the Income Taw Act 1942 is estimated to raise is approximately equal to the total amounts which would have been raised by the Common- wealth and the States from income tax payable under the existing 65 C.L.R.] OF AUSTRALIA. State Acts and the previous Commonwealth Acts. Sec. 6 provides for the payment of additional financial assistance to any State if the Treasurer of the State is of the opinion that the payments under sec. 4 are insufficient to meet the revenue requirements of the State. Sec. 7 provides that payments in accordance with the Act shall be made out of the Consolidated Revenue Fund of the Commonwealth, which is appropriated accordingly by the Act. It is clear from sec. 4 that the Commonwealth Parliament recog- nizes that the concurrent or separate State powers of taxation will continue. The Act is indeed based on that assumption. The assumption is a correct one. It is to be presumed that the Parlia- ment fully appreciated that it might be inexpedient or impracticable for the States or any one or more of them to collect income tax for their own or its purposes after the increased Commonwealth demands were satisfied. If a State does not impose income tax, that would be only because the taxable capacity of its citizens would be practically exhausted by the payment of the Commonwealth taxation, which, by force of sec. 31 of the Income Tax Assessment Act 1942, takes priority on account of the supremacy accorded by the Con- stitution to Commonwealth law. In these circumstances the amount set against the name of the State and possibly a further amount is payable to the State out of the Commonwealth Consolidated Revenue Fund. The Act leaves to the Commonwealth Treasurer to ascertain whether the State has imposed income tax or not. It is a misunder- standing of the provisions of the Act to say that it requires the States to cease imposing income tax under penalty of forfeiting the amounts set against their names respectively : it is also a misunderstanding of the Act to say that the grant is offered upon condition that the States agree not to impose income tax. The Commonwealth Parlia- ment is neither using a stick to beat the States nor offering a bunch of carrots. The Commonwealth Parliament has, in the exercise of its clear constitutional rights, tremendously increased the burden of Commonwealth taxation, and given priority to that burden. It has left the States free to decide whether they should impose an additional burden of taxation in any financial year. The Act pro- vides that, if "' the Treasurer is satisfied that a State has not imposed a tax upon incomes," the amount specified in the schedule is payable to that State. The payment is in truth and in fact made to relieve a disability arising from the incorporation of the State in the Com- monwealth. The money is paid to reimburse the State for the loss of revenue which it has not been expedient to collect because of the circumstances flowing from the operation of valid Commonwealth law. The money is paid out of Commonwealth revenue. The Act H.C. or A. 1942. SH Sourn AUSTRALIA v. THE Common- WHALTH. McTiernan J. H. C. or A. 1942, Se Sourn AUSTRALIA Vv THE Common- WEALTH. McTiernan J. HIGH COURT (1942. is therefore in substance a law granting financial assistance to any State to which it becomes payable. It is a mistake to say that the Income Tax Acts and the States Grants Act are interdependent parts of a law for the collection and disbursement of taxation. The relation between the Acts is that the States Grants Act is consequential upon the Income Tax Acts. This is a legitimate relationship, and, indeed, entirely harmonious with the spirit of federalism. It was said by the Judicial Committee in Moran's Case (1) that although a Commonwealth Act imposing taxation should contain no discriminatory provisions violating sec. 51 (ii.), yet, if it were followed by a Commonwealth appropriation Act " authorizing exemptions, abatements or refunds to taxpayers in a particular State " it would be impossible to separate the Acts in considering the effect of sec. 51 (i.), "" or to turn a blind eye to the real substance and effect of Acts passed by the Federal Parliament at or about the same time, if it appears clear from a consideration of all the Commonwealth Acts that the essence of the taxation is discriminatory " (2). The con- ditions contemplated do not exist here. The States Grants Act is an appropriation Act, but it does not authorize exemptions, abate- ments, or refunds of tax to taxpayers in any States. The real sub- stance and effect of this Act is to grant financial assistance to the States. The real substance and effect of the Income Tax Act is to impose taxation. Sec. 51 (ii.) empowers the Commonwealth Parliament to make laws with respect to taxation, " but so as not to discriminate between the States or parts of States." The argument that the Parliament has infringed this restriction is answered by the following statement from the judgment of the Judicial Committee in Colonial Sugar Refining Company Limited v. Irving (3) : "The rule laid down by the Act is a general one, applicable to all the States alike, and the fact that it operates unequally in the several States arises not from anything done by the Parliament, but from the inequality of the duties imposed by the States themselves." According to the doctrine of Farey v. Burvett (4) the States Grants Act may possibly be justified as an exercise of the defence power, because it secures to the States for the period of the war a flow of financial assistance which aids the maintenance of services which are capable of aiding the successful prosecution of the war. The Income Lax (War-time Arrangements) Act 1942.—This Act describes itself as: "An Act to make provision relating to the (1) (1940) A.C. 888; 63 C.L.R. 338. (3) (1906) A.C., at p. 367.

This Act was assented to on the same day as the other Acts. It is expressed to come into operation from then, 7th June 1942, and to continue in operation until the last day of the first financial year to commence after the end of the present war. The provisions of this Act have already been set out, and I shall not repeat them except to refer briefly to the provisions which are in sec. 4 with respect to the temporary transfer of officers. Jf these provisions are valid, those relating to the transfer of office accommodation, furniture and records can be supported by the same reasoning. There may be separate but less general ques- tions arising under other sections upon which it is unnecessary now to pass an opinion. In brief, this Act transfers temporarily to the Public Service of the Commonwealth from employment under the Crown in right of a State, officers who are engaged on duties which, in the opinion of the Commonwealth Treasurer, are connected with the assessment or collection of taxes upon incomes. The Act is not self-executing. In order to effect the transfer, it is necessary for the Treasurer to give a notice to the State Treasurer. The transfer is effected by the notice. It notifies this Minister that as from the date specified it is, in the opinion of the Commonwealth Treasurer, "necessary for the efficient collection of revenue required for the prosecution of the war, for the effective use of manpower or other- wise for the defence of the Commonwealth," that the officers specified in the notice should be temporarily transferred to the Public Service of the Commonwealth. The officers are transferred by force of the notice as from the date specified, and are retransferred by the Act to the State Service immediately after the Act ceases to operate, unless sooner transferred. The Act contains detailed provisions protecting the rights of transferred officers. In Farey v. Burvett (1) the War Precautions Act, No. 10 of 1914, as amended by the Act No. 3 of 1916, was impeached. The attack went to so much of the Act as purported to authorize the Governor- General to make Regulations and Orders. The Act No. 3 of 1916 purported to authorize the Governor-General to make such Regula- tions as he thought desirable for the more effectual prosecution of the war, or the more effectual defence of the Commonwealth, " prescrib- ing and regulating" a number of matters. The attack on the Act failed. Griffith C.J. said: "If the attack is transferred, as it must be, to the Regulation, that is, if it is treated as a denial of the desir- ability of making it at the time when it was made, the question, though not formally the same, is the same in substance.

HIGH COURT [1942. expressly designates the Governor-General as the person to determine that question of fact. How can this Court say that it will assume the function of revising his opinion? In this aspect of the case Lloyd v. Wallach (1), decided by the Court last year, is exactly in point, and is conclusive " (2). The question arising under the present Act is whether the legislative powers of the Commonwealth extend to the enactment of the provisions in sec. 4. The preamble has already been quoted. Parliament has declared on the face of the Act that its provisions are " necessary and convenient " for the more effectual prosecution of the war. Referring to such a declaration on the face of the Act challenged in Farey v. Burvett (3), Higgins J. said :—' It is not for this Court to decide that the Act does aid defence or how it aids defence ; it is enough that it is capable of being an Act to aid defence, enough that the statement of Parliament is not neces- sarily untrue. Appellants' counsel urge that it is for this Court to decide whether the military necessities now existing are sufficient to justify the Act—or, as finally stated, whether this Act is capable of being a defensive Act in the circumstances of the country. In my opinion, this is not our function" (4). I agree with these views. The transfer of these officers to the Commonwealth Public Service which has the duty of collecting the revenue of the Commonwealth is capable of conducing to defence. The dependence of defence on revenue is an obvious truth. The transfer of these officers will provide the Commonwealth with a skilled staff, and enable it to collect its revenue promptly and efficiently : it will place the collec- tion of the revenue in the hands of officers who will be temporarily under its own control. At present in five States Common- wealth income tax is being collected by State officers. This Act will enable the Commonwealth to dispose the officers collect- ing its revenue at whatever places in the Commonwealth it thinks fit. It could not do this if the officers were not trans- ferred to the Commonwealth Service. These are some of the considerations which point to the possibility at least of a relation between the provisions of sec. 4 and defence. In my opinion these provisions are within the powers vested in the Parliament to make laws with respect to defence and matters incidental to the execution of this power. It follows that sec. 4 and the provisions relating to the transfer of office accommodation, furniture, equipment and records operate with the full force of their words as valid Common- wealth laws. There is no special provision in the Constitution (1) (1915) 20 C.L.R. 299. (3) (1916) 21 C.L.R. 433. (2) (1916) 21 C.L.R., at pp. 443, 444. (4) (1916) 21 C.L.R., at p. 460. 65 C.L.R.] OF AUSTRALIA. exempting the States or State officers from the operation of Common- wealth legislation under sec. 51 (vi.), that is, the defence power. The reasoning of the Court in the Engineers' Case (1) applies to sec. 51 (vi.). There the Court was dealing with the question whether Commonwealth legislation under sec. 51 (xxxv.)—' industrial disputes "—bound the Crown in right of a State when party to an industrial dispute. The Court said :—" Sec. 51 (xxxv.) is in terms so general that it extends to all industrial disputes in fact extending beyond the limits of any one State, no exception being expressed as to industrial disputes in which States are concerned ; but subject to any special provision to the contrary elsewhere in the Constitu- tion. The respondents suggest only sec. 107 as containing by implication a provision to the contrary. The answer is that sec. 107 contains nothing which in any way either cuts down the meaning of the expression ' industrial disputes' in sec. 51 (xxxv.) or exempts the Crown in right of a State, when party to an industrial dispute in fact, from the operation of Commonwealth legislation under sec. 51 (xxxy.). Sec. 107 continues the previously existing powers of every State Parliament to legislate with respect to (a) State exclusive powers and (6) State powers which are concurrent with Common- wealth powers. But it is a fundamental and fatal error to read sec. 107 as reserving any power from the Commonwealth that falls fairly within the explicit terms of an express grant in sec. 51, as that grant is reasonably construed, unless that reservation is as explicitly stated" (2). Sec. 107 does not cut down the natural meaning or general operation of sec. 51 (vi.). The assumption that has to be adopted is that in the present emergency the transfer of officers experienced in the assessment or collection of tax from the State to the Commonwealth service for the duration of the war is capable of conducing to defence. It follows that the Income Tax (War-time Arrangements) Act is a law with respect to defence, and binding on those officers and on the States. The Act is in substance and effect a law of defence, and with respect to matters incidental to the execution of that power. There is nothing in its provisions to support the contention that it is part of a legislative scheme which is in excess of the powers of the Commonwealth Parliament. The Act does not take away from the States their constitutional powers of taxation nor purport to do so. It is nothing to the point to mention the difficulties and trouble which the States may have in engaging other persons to take the place of the officers who are transferred to the Commonwealth service or to replace the material things taken over by the Commonwealth.

In my opinion that question should be answered in favour of the defendants, and there should be judgment for them in each case. Witirams J. In these actions four States, South Australia, Victoria, Queensland and Western Australia, and their respective Attorney-Generals, have each sued the Commonwealth of Australia and its Treasurer claiming a declaration that the whole or some one or more of the following Acts, the States Grants (Income Tax Reim- bursement) Act, No. 20 of 1942, the Income Tax (War-time Arrange- ments) Act, No. 21 of 1942, the Income Tax Assessment Act, No. 22 of 1942, and the Income Tax Act, No. 23 of 1942, or some part or parts thereof, are or is ultra vires the Parliament of the Common- wealth and are or is unconstitutional and invalid and the scheme of uniform taxation embodied in these Acts is unconstitutional and invalid. The surrounding circumstances under which the four Acts were passed can be shortly stated as follows :— Since 1915 the Commonwealth and the States have each been levying income taxes, with the result that, during the financial year commencing on Ist July 1941, there were in the Commonwealth and the several States some twenty-three taxes on income, many of them differing not only in the rate but also in the basis of assess- ment. Since the outbreak of war, the Commonwealth Parliament has been increasing the rates of Federal income tax, particularly on the higher incomes, to an unprecedented extent. Most taxpayers who have to pay Commonwealth income tax have also to pay income tax in at least one of the States. As the incidence of taxation varies considerably in the States, the Commonwealth Government has not been able to use for its own purposes what it considers to be the full taxable capacity of many taxpayers in a less highly taxed State without imposing an unsupportable burden on a taxpayer at the same income-tax level in a more highly taxed State, by reason of the aggregate of Commonwealth and State taxes. In some cases the combined rates of these taxes for the above financial year exceeded twenty shillings in the pound. The taxable capacity of the community has been rising, largely from the defence expenditure 65 C.L.R.] OF AUSTRALIA. of the Commonwealth. The States, in addition to increased receipts H.C. or A. from their railways, have been relieved from expenditure on unemploy- ment, which has greatly decreased, and the Commonwealth has assumed responsibility for child endowment and widows' pensions. The Commonwealth Government considers that, as the financial responsibilities of the States have diminished, whilst its own expen- diture has increased enormously, the only amount of revenue previously derived from income tax which can be made available to the States during the further continuance of the war, without prejudice to its own growing requirements, will be an amount in the case of each State approximately equal to the average of the amounts raised by that State by means of income tax in the financial years commencing Ist July 1939 and Ist July 1940. The amounts payable to each State on this basis are those which appear in the schedule to the Grants Act. The Commonwealth Government also considers there is a serious waste of manpower involved in the admin- istration of twenty-three different taxes by the taxation depart- ments, and in taxpayers having to comply with several Acts, many of which require the payment of the tax in instalments by deductions from wages and dividends. In these circumstances the four Acts were passed, all being assented to on 7th June 1942. The Grants Act came into operation on Ist July 1942, while the other three Acts came into operation on the day they received the Royal Assent. The Grants Act and the War-time Arrangements Act each contain a concluding section that they shall continue in opera- tion until the last day of the first financial year to commence after the date on which His Majesty ceases to be engaged in the present war, and no longer. The preamble to the War-time Arrangements Act states that it is necessary or convenient to provide for the matters set out in the Act with a view to the public safety and defence of the Commonwealth and the several States and for the more effectual prosecution of the war in which His Majesty is engaged. By sec. 4 of the Grants Act it is provided that, in every financial year during which the Act is in operation in respect of which the Commonwealth Treasurer is satisfied that a State has not imposed a tax upon incomes, there shall be payable by way of financial assistance to that State the amount set forth in the schedule to the Act against the name of that State, less an amount equal to any arrears of tax collected by or on behalf of that State during that financial year. Sec. 31 of the Assessment Act provides (so far as material) that, for the better securing to the Commonwealth of the revenue required 1942. Se Sourn AUSTRALIA OF THE Common- WEALTH. Williams J.

Sec. 32 provides that the amendments effected by the Act, other than that effected by sec. 31, shall apply to all assessments for the financial year beginning on Ist July 1942 and all subsequent years. The Tax Act, sec. 7, provides that the tax imposed by the Act shall be levied and paid for the financial year beginning on Ist July 1942, and that, until the commencement of the Act for the levying and payment of income tax for the financial year beginning on Ist July 1943, the Act shall also apply for all financial years subse- quent to that beginning on Ist July 1942. Several decisions of the Privy Council, including Attorney-General for Ontario vy. Reciprocal Insurers (1), In re Insurance Act of Canada (2), Attorney-General for Alberta v. Attorney-General for Canada (3), W. R. Moran Pty. Ltd. v. Deputy Commissioner of Taxation (N.S.W.) (4), and the decision of this Court in R. v. Barger (5), establish that, when the question for determination is whether an Act of Parliament infringes some overriding constitutional provision, the Court must examine the substance and purpose of the Act in order to discover what it is the legislature is really doing. Where there are several Acts having, as in the present case, a clear interaction, the Court is entitled to investigate the substance and purpose of each Act in the light of the knowledge disclosed by them all. The Yaa Act is an Act which levies an income tax estimated to produce £145,000,000. The rates rise steeply, reaching 18s. in the pound at £2,100 on income from property, and 16s. 6d. in the pound at £2,500 and 18s. in the pound at £4,000 on income from personal exertion. As the Act imposes the same rates of tax on all incomes which it taxes, it does not discriminate between States or parts of States considered as geographical entities, and therefore complies with sec. 51 (ii.) of the Constitution (Cameron v. Deputy Federal Commissioner of Tawation (Las.) (6) ). It deals with one subject of taxation only, and so conforms to sec. 55 of the Constitution. The States admit that if the Commonwealth Parliament had passed the Tax Act alone, this would have had the practical economic effect of driving the States out of this field of taxation at least in the case of (1) (1924) A.C. 328. (4) (1940) A.C. 838; 63 C.L.R. 338. (2) (1932) A.C. 41 (5) (1908) 6 C.L.R. 41. (3) (1939) A.C. 117.

They contend, how- ever, that but for the Grants Act, by which the Commonwealth pro- poses to reimburse the States for the loss of income tax to the extent of £33,489,000, the Parliament could have imposed lower rates sufficient to raise a total amount reduced by this sum, in which event a taxable margin would have been left out of which the States could raise a sufficient sum by way of income tax for their own purposes without exceeding the financial capacity of their citizens. But to draw such a conclusion would be pure surmise. If the Grants Act is valid, such assistance would be a Federal purpose under sec. 96 of the Constitution. None of the Acts provide for any rebates, if the States refuse the grants. The whole £145,000,000 is called up finally in any event. It is all payable, like other revenue of the Commonwealth, into the Consolidated Revenue Fund. No part of it is earmarked to pay the grants. At a time when the Commonwealth is floating frequent loans to enable it to meet its commitments, it is idle to suggest that the whole of the tax is not required for Federal purposes. The Yaa Act is, in my opinion, an unexceptionable, if to many people a somewhat painful, exercise of the power to tax. It was strongly urged that the condition in sec. 4 of the Grants Act is unlawful because it requires a State to surrender its sovereign — rights to levy income tax in order to qualify for a grant. Sec. 96 of the Constitution authorizes the Commonwealth Parliament to grant financial assistance to any State on such terms and conditions as the Parliament thinks fit. The grants to each State are not made conditional upon acceptance by all the States. A separate offer is made to each State. The offer is made upon an annual basis, so that if a State which accepts a grant the first year finds it an insuffi- cient reimbursement it will be able to refuse the grant in subsequent years. There is no illegal interference with the sovereignty of the States, because the matter of levying or not levying their own income tax is left entirely to the discretion of their own Parliaments. An analogous case would be where the Commonwealth Parliament offered a State assistance on condition it ceased to carry on the mining of a profitable ore, which the Commonwealth thought it was inadvisable to exhaust in the national interest, the Commonwealth offering the State assistance under sec. 96 to offset the loss of revenue it would suffer by doing so. The present case may be summed up as follows. The Parliament, when the Commonwealth is in imminent danger, considers that it is not in the national interest for the States to levy 1942. Sa SourH AUSTRALIA vu THE Common- WEALTH. Williams J. H. ©. or A. 1942, Sy Sourn AUSTRALIA vw. THE Common- WEALTH, Williams J. HIGH COURT (1942. income tax. But it recognizes that, if they co-operate by agreeing not to do so, they will require financial assistance to reimburse them for their loss of revenue. So it makes its offer of assistance depen- dent on their co-operation. The condition is one which is capable of aiding in the defence of the realm. Sec. 5 offers an inducement to the States to collect their arrears of tax in respect of the financial years up to and including that of Ist July 1941. It is a fair and equitable provision, as it gives to all States ultimately the benefit of all the taxes they levied prior to the Tax Act coming into force. Faint objection was taken to sec. 6 of the Act on the ground that Parliament and not the Treasurer must fix the amount of a grant ; but, as Latham C.J. pointed out in Deputy Federal Com- muassioner of Taxation (N.S.W.) v. W. R. Moran Pty. Ltd. (1), where several authorities are cited : " It is too late now to argue that terms and conditions determined by a Minister under such legislation are not determined by the Parliament." The allotments to the State are not made on any ratable basis, but sec. 96 does not prohibit dis- crimination, and grants may be made to one State and not to others and between the States on an unequal basis. Under the circum- stances the Grants Act is, in my opinion, a valid exercise by the Parliament of its powers under sec. 96. Although the language of sec. 31 of the Assessment Act is not as clear as it might be, I agree with Mr. Ham that it means Common- wealth income tax on the income of any year of income must be paid in priority to the State tax for that year of income, so that, once the Commonwealth tax for any financial year has been paid, the section does not prevent a taxpayer from then paying his State tax for that financial year. Counsel for the States contended that, as both the Commonwealth and State Parliaments are entitled by the exercise of their sovereign rights to impose income tax, there can be no inconsistency between the two impositions, each of which operates concurrently but independently of the other, so that it is not an exercise of the taxing power or incidental thereto for the Commonwealth to provide that its tax shall be paid in priority to that of a State. But the Privy Council in In re Silver Bros. Ltd. (2), and the majority of the Justices of this Court in Federal Commis- stoner of Taxation v. Official Liquidator of E. O. Farley Ltd. (3), appear to me to have considered, I would respectfully say correctly, that it is possible for the Canadian and Australian national Parlia- . ments respectively, by aptly framed legislation, to give priority to their taxation statutes over those of the Provinces in the case of (1) (1939) 61 C.L.R. 735, at p. 763. (2) (1982) A.C. 514. (3) (1940) 63 C.L.R, 278. 65 C.L.R.] OF AUSTRALIA. Canada and of the States in the case of Australia, where they come 1. ©. oF A. into conflict in the same field in the sense that a taxpayer who has to pay the two exactions is unlikely to be able to meet them both in full. In Jn re Silver Bros. Ltd. (1) Viscount Dunedin said : "The two taxations, Dominion and Provincial, can stand side by side without interfering with each other, but as soon as you come to the concomitant privileges of absolute priority they cannot stand side by side and must clash; consequently the Dominion must prevail." After pointing out, quite rightly, that each of these decisions relates to the liquidation of a company, counsel for the States contended in the alternative that, even if the Commonwealth can make its tax a prior charge upon a taxpayer's assets, it would still not be incidental to the taxation power to prevent a taxpayer from paying his debts, including a State assessment, as they become due. It would be impossible to make an income tax a fixed charge on a taxpayer's assets generally, some of which he is acquiring and disposing of from day to day, while many taxpayers would not possess particular assets of an appropriate nature to be charged specifically. Grave difficulties would be encountered in evolving and heavy expense incurred in administering a system of fixed charges. The only practical way, therefore, to prefer the Common- wealth debt would be to provide that it should be paid in priority to the State debt. To do this would not be to manufacture incon- sistency between Federal and State laws. It would be a means of aiding the effective operation of the power comparable to the right of the Commonwealth under the borrowing power, sec. 51 (iv.), to make its loans attractive to investors by freeing them from State taxation (The Commonwealth v. Queensland (2) ). It would be strange if the Commonwealth could protect interest on its loans from State taxes, but could not take effective measures against the States to ensure the getting in of revenue required to pay the interest. The section is, in my opinion, a valid exercise of power. Under arrangements made with the States pursuant to the Income Tax Collection Act 1923 the Commonwealth in Western Australia is at present collecting its own income tax and the income tax of that State through its own income tax department, while, in the other States, the State income tax departments are collecting their own income tax and that of the Commonwealth. The affidavits filed on behalf of the States show that they each maintain a department for the collection of State income taxes, in which a large staff is employed consisting of officers the senior members of whom have (1) (1982) A.C., at p. 521.

HIGH COURT [1942. spent many years in the department and thereby acquired a special- ized knowledge of the administration of the State's income tax Acts. Hach department uses for the purposes of its work large numbers of typewriters, adding machines and other mechanical equipment. They are housed in extensive offices in their respective capital cities, and, in the present conditions, it would be impossible or impracticable to replace their personnel or equipment or to find other suitable premises for their accommodation. The Arrangements Act provides for the suspension of the existing arrangements with the States for the assessment and collection of income tax, and the assessment and collection of the tax imposed by the Zax Act in all States by the Commonwealth from a date fixed by proclamation until the Act ceases to operate; for the compulsory temporary transfer of officers employed by the States in assessing and collecting income tax to the Public Service of the Commonwealth and their subsequent retransfer to the States; for the compulsory temporary use by the Commonwealth of any office accommodation, furniture and equipment owned by a State; and for the compulsory permanent acquisition by the Commonwealth of any records in the possession of a State relating to the assessment and collection of Commonwealth income tax. The Act applies to all State servants, permanent or temporary. The transfer to the Commonwealth Public Service is effected by the Treasurer of the Commonwealth addressing a notice in writing to the Treasurer of a State. The transfer can be called for if, in the opinion of the Treasurer of the Commonwealth, it is necessary for the efficient collection of revenue required for the prosecution of the war, for the effective use of manpower, or otherwise for the defence of the Commonwealth. The rights conferred upon the Treasurer of the Commonwealth with respect to the office accommodation, furniture and equipment of the States are also very extensive. He can demand the temporary possession and exclusive use of this property for the Commonwealth when it is required for the efficient collection of revenue, for the effective use of manpower, or otherwise for the defence of the Com- monwealth, The Act provides that, in default of agreement between the parties, compensation for the possession and use of such property and the obligations of the Commonwealth with respect to keeping it in good order and repair and otherwise shall be determined by an arbitrator appointed by the Governor-General. No compensation is provided for the acquisition of the returns and records, but the States are given the right to have access to and inspect those which relate to the assessment or collection of any tax imposed upon income by or under any law of the State. No argument was addressed to the 65 C.L.R.] OF AUSTRALIA. Court whether the entry into the possession and use of the office 4. © oF A. accommodation, furniture and equipment or the transfer of the returns and records would be an acquisition by the Commonwealth of State property within the meaning of sec. 51 (xxxi.) ; or whether, if it is, provision for an arbitration by an arbitrator appointed by the Federal Executive Council and therefore in effect by one of the parties is a compliance with the placitum; or whether a right given to a State, from whom the returns or records are acquired, to have access to and to inspect them is a fair equivalent for their value ; so I shall not express any opinion on these points. It is obvious from the framework of the Act as a whole that it is sought to justify its constitutional validity as an exercise of the defence power. In what Mr. Ham described as the piping times of peace there could be no question, I should imagine, that the collection of taxes would be incidental to the execution of the taxation and not the defence power. The defence power does not become in time of war a paramount power (Andrews v. Howell (1), per Starke J.), but, as Dixon J. pointed out in the same case (2), though its meaning does not change, "its application depends upon facts, and as those facts change so may its actual operation as a power enabling the legislature to make a particular law." In Farey v. Burvett (3) Isaacs J. said: (It is) "a power which is commensurate with the peril it is designed to encounter, or as that peril may appear to the Parliament itself ; and, if need be, it is a power to command, control, organize and regulate, for the purpose of guarding against that peril the whole resources of the continent, living and inert, and the activities of every inhabitant of the territory. The problem of national defence is not confined to operations on the battlefield or the deck of a man-of-war ; its factors enter into every phase of life, and embrace the co-operation of every individual with all that he possesses—his property, his energy, his life itself." The necessary steps to meet the peril depend so greatly upon the knowledge of the Parliament and the Executive it controls that the Court, in deter- mining whether a particular Act is within the ambit of the power, is only concerned to see that its provisions are such as to be capable even incidentally of aiding the effectuation of the power. After that the Court must stay its hand, for "no authority other than the central Government is in a position to deal with the problem which is essentially one of statesmanship" (per Viscount Haldane when delivering the judgment of the Privy Council in Fort Francis Pulp and Power Co. v. Manitoba Free Press Co. (4) ). (1) (1941) 65 C.L.R., at p. 268. (3) (1916) 21 C.L.R. 433, at p. 455. (2) (1941) 65 C.L.R., at p. 278. (4) (1923) A.C. 695, at p. 706. 1942.

Adelaide Steamship Oo. Ltd. (1), Know C.J., Isaacs, Rich and Starke JJ., in their joint judg- ment, said :—"It is undoubted that those who maintain the authority of the Commonwealth Parliament to pass a certain law should be able to point to some enumerated power containing the requisite authority. But we also hold that, where the affirmative terms of a stated power would justify an enactment, it rests upon those who rely on some limitation or restriction upon the power, to indicate it in the Constitution " (2). It was there held that States and their agencies, when parties to industrial disputes in fact, are subject to Commonwealth legislation under placitum xxxv. of sec. 51 of the Constitution, if such legislation on its true construction applies to them. This is because, when States become merchants and traders and engage in industrial activities which the general public may carry on, the subject matter of the power conferred on the Parliament by this placitum is such as to embrace States acting in such a capacity as well as individuals within its scope. Applying the principles laid down in the Engineers' Case (1), there can be no doubt, in my opinion, that States, like individuals, are within the ambit of the defence power, so that, where it is incidental to the execution of the power to take some action to meet an emergency which affects rights which in normal times are within the domain exclusively reserved to the States by the Constitu- tion, the Commonwealth Parliament can do so. In Farey v. Burvett (3) legislation under the power was held to be valid, although relating to a subject matter, i.e., the price of bread, which in times of peace would have been only within the powers of the States. Any attempt at State legislation on this subject which came into collision with the Federal Act would have been to that extent void under sec. 109 of the Constitution. But in times of peace the State legislation would have been valid and the Commonwealth legislation invalid. In mobilizing the resources of the nation under the defence power, the Parliament has the same right to call for the services of those employed by the States as of those employed by private employers, and the same power to enter into possession of property owned by the States as in the case.of property privately owned. Tf the real substance and purpose of a statute is incidental to defence, then, however seriously its operation may hinder the carrying on of the government of a State, this would simply be the indirect result of the lawful action of the Commonwealth undertaken to meet the (1) (1920) 28 C.L.R. 129. (2) (1920) 28 C.LR., at p. 154. (3) (1916) 21 C.L.R. 433. 65 C.L.R.] OF AUSTRALIA. national emergency. It is one thing for the Commonwealth Parlia- ment to attempt directly to prevent a State exercising its legislative, judicial, or executive functions, which would be an illegal mterference with the prerogative rights of the State, and quite another thing to claim the services of a body of individuals employed by or the possession of property owned by a State where the employees and property are organized, as they are here, so as to possess some special attribute capable of advancing the total war effort. But legislation which appears to discriminate against a State by the mass transfer of its public officers in one department and the exclusive acquisition of its property must be carefully scrutinized to see that its real substance and purpose is to assist defence and not under colour of such a purpose to intermeddle in the sovereignty of a State. The affidavits filed on behalf of the States them- selves show that the collection of the new tax would be gravely impeded if the Commonwealth had to organize a new depart- ment in every State except Western Australia. It was suggested that the existing arrangements, which have worked satisfactorily since 1923, should be allowed to continue. Their provisions are not before us, but it appears that they would have to be at least revised because, if the Commonwealth is to become during the war the sole income-tax authority, the expense which is now shared between the Commonwealth and the States will become the sole burden of the Commonwealth. The only reason Mr. Ham gave for the Commonwealth requiring a transfer of the officers and accommodation was that, as the tax was being collected on behalf of the Commonwealth, it ought to have control of its own affairs. It is not for us to weigh the merits of this reason. The question whether the Commonwealth should have direct control or should have to rely upon an agent to perform this important work is one of policy which must be decided by the Government and not by the Court. It is clear that an Act to enable the Treasurer to get in expeditiously the sinews of war to the extent of £145,000,000 can assist in the prosecution of the war, and is, therefore, incidental to the execution of the power of defence. If the Commonwealth could call up all officers by some form of legislation, and this must, I think, be conceded, it is a matter of convenience and not of substance that the Act provides for the Treasurer of the Commonwealth giving the notice to the Treasurer of a State instead of to each officer personally. Secs. 5-10 of the Act contain provisions with respect to the pay of transferred officers whilst in the service of the Commonwealth and their rights on death, retirement, or at the conclusion of their H. C. or A. 1942. SH Sourn AUSTRALIA Vv THE ComMon- WEALTH. Williams J. H. C. or A. 1942. Se Sourn AUSTRALIA Oy THE CoMMON- WEALTH. Williams J. HIGH COURT [1942. service with the Commonwealth. Whilst they are employed by the Commonwealth they are to receive the same pay from the Commonwealth as, but for the transfer, they would have received from the State. Upon retirement they are retransferred to the State and become entitled to the same pension and other benefits they would have received if they had not been transferred. The sections provide for the continuation of payments to superannuation funds by the officers themselves, and, the Commonwealth making the same payments as a State would have made if they had been serving the State. The Commonwealth also contributes to pensions or other payments which dependents of officers who die become entitled to receive from the State, the respective obligations of the Commonwealth and the State being adjusted on the basis of the officers' length of service with the Commonwealth and the State. A transferred officer is deemed to be an officer of the State for the purpose of promotion or transfer from a temporary to a permanent position. The purpose of the sections is to provide a scheme to prevent officers suffering from the temporary transfer, the Common- wealth taking over a fair share of the burdens of any emoluments which would have accrued from long service if their employment by the State had been continuous. In America it has been held that, under the commerce power, Congress can legislate to prevent any person engaging in unfair labour practices which affect com- merce. The National Labor Relations Act 1935, after defining unfair labour practices, by sec. 10 (c) authorized a Board to require the reinstatement of employees who had been discharged for engaging in trade union activities which the Act authorized them to engage in against the wishes of their employers. The Supreme Court held the provision to be valid. It did not interfere with the contractual relationship of the parties except to the extent necessary to give effect to the policy of the Act (National Labor Relations Board v. Jones & Laughlin Steel Corporation (1) ). So, under the defence power, the Commonwealth can, in my opinion, legislate with respect to the reinstatement of citizens called up for some national duty, to prevent them being prejudiced in their civil employment when their services are no longer required for this purpose. The present Act purports to do nothing more. It does not deprive the States of any rights the States would have against the officers on the basis that they had not been transferred. The States can legislate as freely as before to affect any existing rights of public servants with respect to pay, contribu- tions to superannuation funds, amounts of pensions, and so on, and the officers transferred to the Commonwealth will be bound by all (1) (1937) 301 U.S. 1, at pp. 45-48 [81 Law. Ed. 893, at pp. 916-918]. 65 C.L.R.] OF AUSTRALIA. such legislation. If the Commonwealth Parliament can pass legis- H- C. oF A. lation making awards binding on the States under the conciliation and arbitration power, it would be a strange result if, under the defence power, it cannot legislate with respect to the reinstatement of men employed by a State and called up by the Commonwealth for national service in the same way as it can legislate for this purpose with respect to private employers. It is suggested that the powers conferred on the Treasurer are in terms wide enough to enable him to call up any officers whom a State, in order to collect arrears of or to levy its own income tax, might engage from time to time to replace those who had been transferred, and to take possession of any new office accommodation they might commence to use for this purpose ; but the Treasurer can only call up officers, on the recom- mendation of the Public Service Board, if they are required in the Public Service of the Commonwealth for one of the three purposes mentioned ; and it is preposterous to believe that the Public Service Board and the Treasurer would conspire together to call them up when they were not required, and thereby deliberately overstaff the Commonwealth Public Service at the expense of the taxpayers in order to deprive a State of their services. To do so would be to make a colourable use of the power which could be restrained by the Court. The Grants Act, sec. 4, contemplates that existing arrears of State income tax will be collected, if necessary, by the Common- wealth, and it is to the advantage of both the Commonwealth and the States that they should be got in. The Arrangements Act is, in my opinion, a valid exercise of the defence power. As it is with considerable diffidence that I have reached a different conclusion from that arrived at by the Chief Justice and my brother Starke with respect to the validity of this Act, I desire to say that, even I considered the Act invalid, this would not affect the validity of the Tax Act, the Grants Act, or sec. 31 of the Assessment Act. The States also allege that the effect of the Acts regarded as a single legislative scheme is to spread the burden of existing Com- monwealth and State income taxes over the taxpayers of the Com- monwealth as such and thereby to effect a discrimination between the States and the taxpayers of each State as such by reference to the varying rates of income tax at present in force therein. It is sufficient to say with respect to this contention that, although admittedly taxpayers in the different States previously paid income tax to a State and the Commonwealth at varying aggregate rates, this was due to the difference in the taxation laws of the States and not to the law of the Commonwealth (Colonial Sugar Refining Co. 1942. Ke Sourn AUSTRALIA Vv THE ComMon- WEALTH. Williams J, H, C. or A, 1942. QeH Sourn AUSTRALIA v THE Common- WEALTH, HIGH COURT (1942) Lid. v. Irving (1) ). Taxpayers in the States who paid State income tax at lower rates than those in the other States will now have to pay more to the Commonwealth in comparison, but any attempt by the Commonwealth to make rebates to adjust this position would bring about a result in conflict with the prohibition against dis- crimination contained in sec. 51 (ii.) of the Constitution.
