GENERAL DIVISION On Appeal from the Supreme Court of Victoria Between: THE COMMISSIONER OF TAXATION OF THE COMMONWEALTH OF AUSTRALIA (Appellant) And: HYDROCARBON PRODUCTS PTY. LTD. (Respondents) Coram: Woodward, Wilcox and Ryan JJ. Date: 14 April 1987 REASONS FOR JUDGMENT THE COURT: These proceedings are respectively an application for leave to appeal, and an appeal from orders made in the Supreme Court of Victoria on 22 and 29 October 13986. Those orders were made in the course of an appeal by Hydrocarbon Products Pty. Ltd. ("the taxpayer") under 5.187 of the Income Tax Assessment Act 1936 ("the Act"), against an assessment for the year ended 31 December 1981. In making that assessment, the Commissioner disallowed losses which the taxpayer claimed to be entitled to carry forward, and which ta resulted from deductions claimed in @arlier years pursuant to the investment allowance provisions of sub-division B of Divistan 3 of Part III of the Act. Those deducticans were claimed by reference to expenditure by the taxpayer on the construction of a styrene monomer plant at West Footscray ain the year ended 31 December 1977 when tne taxpayer expended $73,179,329, and the year ended 31 December 1378 when it expended 32,163,044. The taxpayer objected to the disallowance of those losses, On 17 August 1984 that objection was disallowed, whereupon the taxpayer, pursuant to 5.187 of the Act, requested the Commissioner to treat its objection as an appeal and forward it to the Supreme Court of Victoria. That was ultimately done on 27 March 1986. By sub-paragraph 6(d) of its motice of objection the taxpayer contended, inter alia, that the Commissioner should have allowed as a deduction certain eligible expenditure in the sum of $73,179,829 said to have been "of a capital nature in respect of acquisition or construction by the taxpayer of a new unit of eligible property or alternatively certain new units of eligible property in relation to which the said sub-division CB of Division 3 of Part JIIIJ applied being eligible expenditure that was incurred in respect of a unit or alternatively units of eligible property acquired by the taxpayer under a contract entered into on or after Ist us January 1376 or in respect of a unit of eligible property or alternatively units of eligible property constructed by the taxpayer and the construction of which commenced on or after the lst January 1976." Sub-paragraph 6(e) of the same notice of objection was in the following terms: "(a) Further, and without in any way limiting the generality of the foregoing, the eligible expenditure of $73,179,329 was incurred by the taxpayer in the acquisition or construction of a unit of property being a styrene monomer plant or alternatively certain units of property being the various components of the styrene monomer plant or some of them." Similar contentions were advanced in respect of a smaller sum of $867,213 the expenditure of which was said to give rise to an allowable deduction in the substituted accounting period ended 31 December 1978. In that context 1t was contended that the eligible expenditure was incurred in respect of a unit of property or alternatively units of property acquired under a contract entered into before 1 July 1978 or of which the taxpayer commenced construction before that date. It was then contended in the alternative that each of the two sums or some part thereof was an allowable deduction in "some other one or more of the following years and = substituted accounting periods in relation to the taxpayer under the Act namely the 3lst December 1976, the 31st December 1978, the 31st December 1979, the 31st December 1380 and 31st December 1981" upon the grounds mutatis mutandis set forth in relation to the respective amounts in the @e@ariier paragraphs of the On 20 June 1386, Tadgell J., an the Supreme Court of Victoria, ordered the Commissioner to provide particulars of his grounds of disallowance of the objection, and of each statutory provision on which he relied. Pursuant to that order, the Commissianer, on 18 July 1386, provided, amongst others, the following particulars: "4A, More particularly, in relation to the first expenditure and the second expenditure - (a) neither expenditure was of a capital mature incurred by the Appellant on or after lst January 1976 in respect of the acquisition or canstruction by 1¢ of anew unit or units of sub-section 82AA(1) property, as required by 5.82AB(1)(a) of the Act; (Bb) expenditure in respect of each unit of property did noc exceed $500, as required by s.82AB(1)(b) of the Act; (co) neither expenditure had. been incurred in respect of a unit or units of property acquired by the Appellant under a contract entered unto on or after lst January 1976, as required by s.82AB(1)(c)(1) of the Act; or (d) neither expenditure had been incurred in respect of a unit or units of property that was or were constructed by the Appellant and the construction of which commenced on or after Ist January 1976, as required by s.82AB(1){c)(11) of the Act. Further or alternatively, ain relation to the first expenditure and the second expenditure, to the extent to which such expenditure related to plumbing, fixtures and fittings, they were not plumbing, fixtures and fittings to which s.54(2)(c) of the Act applied and accordingly such expenditure was excluded from eligibility for the investment allowance by virtue of s.B2AE of the Act. Further or alternatively, if (which is not admitted) the unit or units of property was or were acquired by the Appellant, such property was excluded from the operation of sub-division B by virtue of the provisions of s.dZAFi(4) of the Act. Further or alternatively, if (which is not admitted) the unit or units of property was or were acquired by the appellant, s.82AL(1) and/or (2) apply by reason whereof the Appellant is not antitled to the deduction claimed." Section 82AB(1) of the Act provides that: "(1) Subject to this Subdivision, where - (a) (b) (ce) on or after 1 January 1976, a taxpayer has incurred expenditure of a capital nature (in this section referred to as 'eligible expenditure' ) in respect of the acquisition or construction by him of a new unit of sub-section 82AA (1) property; the eligible expenditure exceeded $500; the eligible expenditure was incurred - 1) in respect of aunit of property acquired by the taxpayer under a contract entered into on or after 1 January 1976 and before 1 July 1985; or Vii) in respect of aiunit of property that was constructed by the taxpayer and the construction of which Je commenced on or after i January 1375 and before 1 July 1335; and wd) the un1rt of property was firs used or anstalled ready for use before 1 July 1387, there shall be allowed as a deduction from the taxpayer s assessable income of the first year of income during which that unit was either used for the purpose of producing assessable income, or installed ready for use for that purpose, an amount {ain this section referred to as the 'relevant amount') ascertained in accordance with the following provisions of this section." Section B2AF(4) of the Act, to which reference was made in Paragraph 6 of the Commissioner's particulars is in the following terms: "This Subdivision does not apply in relation to property acquired by a taxpayer from another person, being property that was not trading stock of that other person, if that other person acquired the property under a contract entered into before 1 January 1376 or commenced construction of the property before that date." The effect of s.82AC(1), to which the Commissioner referred in paragraph 7 of his particulars, 1s that where the Commissioner is satisfied that a contract or arrangement was entered into by a taxpayer before 1 January 1976 for the acquisition or lease of an original unit of property and the taxpayer, after that date, entered into a contract (whether with the same or another person) for the acquisition or lease of the original unit or another unit in substitution therefor, the Commissioner may refuse to allow a deduction under Subdivision B of Division III of Part III of the Act, 1f one of the purposes for which the taxpayer contracted to acquire or lease the original or substitute unit was that of obtaining a deduction under Subdivision B. Correspondingly, s.82AL(2) gives the Commissioner a discretion to refuse a deduction where he 1s satisfied that on or after 1 January 1976 the taxpayer commenced construction of a substitute unit, or antered into a contract to acquire or lease the original, or a substitute unit, 1f the taxpayer had commenced construction of the original unit before 1 January 1976. Like that ain s.82 AC(1), the discretion conferred by 5.82 AC(2) 15 conditioned upon one of the purposes for which the construction of the substitute unit was commenced or the contract for the acquisition or lease of the original or substitute unit was entered into, having been that of obtaining a deduction under Subdivision B. On 16 September 1986, the Commissioner issued a summons seeking an order that the taxpayer make an affidavit of documents relating generally to the matters in dispute in the appeal. Alternatively, an order was sought requiring the taxpayer to make an affidavit of documents relating to ten specified aspects of the acquisition or construction of each unit of eligible property referred to in the taxpayer's notice of objection. By his order made on 22 October 1986, Tadgell J. dismissed the Commissioner's summons. In the course of his reasons for judgment given on that day, his Honour noted that in support of the summons the Commissioner's officer had sworn that the Commissioner Maintained the view formed "at the time of assessment and Maintained at the time of consideration of the obje ra a cr P ctfu be] ion on further consideration during the course of the subsequent events, that the appellant was not entitled to a deduction for the investment allowance claimed". His Honour also noted that the same officer had sworn that the Commissioner was concerned that, if he did not have: "discovery of the relevant documents and other relevant information prior to the hearing of the appeal it may result in injustice in the conduct of the hearing and determination of the appeal as well as a protraction of the hearing of the appeal by reason of the necessity of the appellant being required to yo to proof of ail aspects of its claim which cculd be avoided uf the orders sought are made". His Honour then criticised those passages and the width of the discovery sought by the Commissioner, saying; "These two statements, 1f not actually inconsis- tent, are not altogether easy to reconcile. Having determined that the appellant's objection should be disallowed, and having taken 16 months to do so, the Commissioner seeks now, before the already long-pending appeal is heard, to have access to every document which could conceivably bear on the question whether the claimed deduction is allowable or not. The extent of the order for discovery sought can only be seen by a consideration of paragraph l(a) and (b) of the summons, which I append as a schedule to these reasons." After referring to the invocation by counsel for the Commissioner of a litigant s general right to discovery ire] arising either by application of the High Court Rules or at common law, his Honour observed, at p.39 of the Appeal Book: "In other words, the Commissioner would seek to require the appellant to catalogue on affidavit every document which might or could - not would - affect the result of the appeal. Thus he seeks, at this stage, to require the appellant to provide information which the Commissioner has not already obtained and which might tend to support his disallowance of the objection. This 15 not, in my opinion, an approach that the Court should ordinarily countenance in proceedings under 5.187: 1t may be doubted whether it is a course which will usually be necessary in order to do justice to the revenue, and I do not consider it to be necessary here. An order for general discovery against a taxpayer such as that now sought in paragraph l(a) of the summons is inappropriate in this case. Moreover, an order for discovery by reference to broadly- described categories of documents such as that alternatively sought by paragraph 1(b) of the summons 18 inappropriate in this case." His Honour then drew support from the judgment of Fullagar J. in George v. Federal Commissioner of Taxation (1952) 86 CLR 183 at 207-208 where it was indicated that because the Commissioner is only nominally a "party" to a so-called taxation appeal, "certain orders which are quite appropriate as between parties to an action are quite inappropriate as between an appellant taxpayer and the Commissioner". From that basis, Tadgell J. continued: "In my opinion the question whether the Commissioner should have discovery in proceedings such as these depends upon the convenience and commonsense of the matter and whether he can fairly meet the appeal without it." Having thus identified the question, his Honour resolved ut against the Commissioner's application For discovery. He was led to that conclusion by the scheme of sub-division B of Division 3 of Part III of the Act which, he suggested, prescribed exclusions of a right to an investment allowance which are "like hurdles that a taxpayer must clear 1f he is to succeed." Against the background of that scheme, it weighed with his Honour that: "It is common ground that the issues have been sufficiently defined here by means of the appellant's notice of objection, on the one hand, and the motice of particulars of the Commissioner s grounds of disallowance of it on the other." Account was also taken of the fact that s.190(b) of the Act rests the onus of proving that an assessment is excessive upon the taxpayer, as to which his Honour said: "The necessity for discovery in favour of the Commissioner of documents or facts is to be considered in the light of the peculiar onus which rests on an appellant by virtue of s.190(b). If, as the affidavit for the Commissioner asserts here, the Commissioner has actually concluded on specified grounds that' the appellant was not entitied to the claimed deduction, the Commissioner has strictly no case to make out upon the hearing of the appeal. It the true position is that the Commissioner i158 simply not satisfied that the appellant has established a claim to the deduction, and has disallowed the claim on that footing, the position 1S in practical terms no different: the Cammissiconer has no case to make. Any hardship to him froma failure to provide him at this stage with access to documents which might support his assessment, or his disallowance of an ll. objection to it, 15 difficuit to perceive unless 1b results from his being taken by Surprise." Reference was then made to the access which the Commissioner already had to a great deal of documentary material, and to the fact that the Commissioner's course of investigation of the taxpayer s entitlement to an investment allowance began long before he examined the appellant 5s return for the 1981 year. From those references his Honour proceeded to this conclusion: "In assessing whether the Commissioner should receive the discovery of documents that he now seeks, I must endeavour to balance - (1) the fair entitlement of the appellant to have the appeal determined by the Court within reasonable limits of time in the Manner contemplated by 5.137 and s5.136A of the Act; and (2) the entitlement of the Commissioner fairly to meet the appeal. IT have had regard to the long history of the matter, to the Commissioner's powers apart from his right to seek discovery, to the extent of the information that he has already received and toa the ultimate benefit and detriment that would he likely to accrue to the one side and the other if the extensive discovery now sought were granted. I am clear that, on balance, the discovery sought should not be allowed. To grant it would involve exceedingly extensive effort, protracted delay and large expense, all calculated to inconvenience and disadvantage the appellant unwarrantably in the hearing and determination of 1ts appeal. On the other hand the Commissioner has not shown that, without the discovery he seeks, he will not be fairly enabled to test and to contest the matters that the appellant must prove." In the context of a reference to Bailey v. The Commissioner of Taxation of the Commonwealth of Australia (1977) 136 CLR 214 and the authorities there cited, his Honour repeated that here full particulars had been supplied on either side. His Honour then acknowledged that he had adverted to the matters referred to by Murphy J. 1n The Myer Emporium Ltd. v. Federal Commissioner of Taxation 85 ATC 4111 at 4113, but went on to observe: "The ussues in the present case are plainly defined; and upon that definition I consider that the appeal 15 in a position fairly to proceed without the discovery that 15 now sought. I recall nevertheless the dictum of Kitto, J., in George v. Federal Commissioner of Taxation 86 CLR 183, 190 which, 1f I may respectfully say so, applies here mutatis mutandis, namely - 'In my opinion 1t would not be consistent with the authorities I have cited, or with the commonsense of the situation, to order particulars. If the Commissioner's case at the hearing of the appeal develops upon lines which the appellant cannot fairly be expected to be ready to meet, the presiding judge will be ina position to ensure that no injustice results.' The summons will be dismissed with costs." After that judgment was delivered, the matter apparently came back to Tadgell J. on 29 October 1386 for further directions. On that occasion, Counsel for the Commissioner requested his Honour to direct that the taxpayer provide particulars of each unit of property which is alleged to be eligible property in respect of which a deduction by way of investment allowance 1s claimed. His Honour refused that request, after noting: "Fiore tne taxpayer, a large body of affidavit material has been filed which, 1t seems to "me, does provide information and all the information upon which the taxpayer will rely in support of 1ts appeal. The identification of andividual units of eligible property, insofar as that is required, seems to be likely to involve to some extent a matter of opinion. Such identification will be a task which the Court will ultimately have to perform upon the available evidence." The Commissioner also sought particulars of each contract referable to the construction or acquisition of each unit of eligible property. That request was similarly refused by his Honour who observed: "Once again, I should think that, on the face of it, 15 not an unreasonable request and, in substance, I should accede to it. The solicitor for the taxpayer this morning, however, has indicated, 1n a fashion which binds the taxpayer and is intended to bind it, that the only contracts relied on are those which are to be discerned from the affidavit material and the exhibits upon which the taxpayer intends to rely and which have been provided to the Commissioner. I think no sensible purpose would be served by directing any further particularisation and I do not do so." A third request by the Commissioner on 29 October 1986 was for a direction that the taxpayer produce for imspection the contracts in its custody, possession or power for the construction or acquisition of each of the units of eligible property, together with any plans and specifications relating to those units. His Honour also refused that request, saying of it: "Tt seems to me that that request 1s too broad. To a great extent, it carries with ait much of the vice of the application for discovery which I have already refused. If there were some specific plan or some plan which could be identified as being necessary for the understanding of the function of the plant which it was necessary for the Commissioner to see, or More than one, then I should certainly direct that he be entitled to see 1t. To impose at this stage on the taxpayer a blanket obligation to disgorge each and every piece of paper which might satisfy the description of a plan or specification relating to the plant 15, 1t seems to me, in all the circumstances, unduly onerous and unnecessary. I refuse the request in the form in which it has been made." The final relevant request made by the Commissioner on 29 October 1986 was that there should be reserved to him a right to seek leave to deliver interrogatories for the examination of the taxpayer and to have a date fixed for the return of a subpoena duces tecum before the date fixed for the hearing of the taxpayer's appeal. Of that request his Honour said: "Without knowing the kind of interrogatories which might be sought, and without having really any idea of what they might be or how far they maght extend, and without having any idea of the kind of subpoena which might be sought to be issued, I find myself unable to make any sensible judgment upon that request. If, hereafter, the Commiss- 1oner can demonstrate to me or to someone else that it 1s appropriate that particular interrogatories be delivered before the case comes on for hearing or that particular documents, which might be the subject of a subpoena, should be produced upon subpoena before the case comes on for hearing, then I _ should think that nothing I do this morning would = shut the Commiss:oner sut from making appropriate application." We have first to determine whether an appeal lies to this Court from orders of the kind which Tadgell J. made on 22 and 29 October 1986, and, if s0, whether such appeal is as of right or by leave. Section 185 of the Act enables a taxpayer to lodge with the Commissioner an objection in writing to an assessment, and by s.187(1) a taxpayer dissatisfied with the Commissioner 5 decision on an objection may request the Commissioner either - "(Cad to refer the decision to a Board of Review for review; or (b) to treat his objection as an appeal and to forward 1t to a specified Supreme Court." Section 196A(1) which applies to, amongst other proceedings, an objection forwarded to a Supreme Court, provides (so far as is relevant) as follows: "... the High Court Rules as in force immediately before the date of commencement of this section under the Judiciary Act 1903-1369 apply, so far as practicable, to and in relation to a proceeding to which this section applies in like Manner as they applied immediately before that date to and in relation to the like proceeding in the High Court." The constitution of a Supreme Court by which an appeal pursuant to 3.137 1.5 to be heard 15 prescribed by 5.137 ain these terms: "Where, at the request of the taxpayer, the Commissioner has treated his objection as an appeal and forwarded it to a Supreme Court, the appeal shall be heard by a single Judge of the Court." The powers in respect of an appeal under 5.197 of a Supreme Court constituted in accordance with that section are enumerated in 5.199 which, at the time relevant to these proceedings, provided: "199. (1) The Supreme Court hearing an appeal under section 197 may make such order as i1t thinks fit, and may by such order confirn, reduce, increase or vary the assessment. (2) An appeal does not lie from an order referred to in sub-section (1) except as provided in section 200." Section 200, in turn, provides that: "The Commissioner or the taxpayer may appeal against an order referred to in section 199 - (a) to the Federal Court of Australia; (b) with special leave of the High Court, to that Court." It will be seen that the legislation does not, in terms, provide for an appeal against an interlocutory order made by a single Judge of a Supreme Court in the course of hearing a .137 of the Act. On one Lf) so-cailed appeal pursuant to construction, 5.199(1) contemplates only a final order disposing of the appeal by confirming, reducing, increasing or varying the assessment. That construction accords a limiting effect to the words "by such order", so that they operate to cut down the very wide discretion which 15 ordinarily conferred by the words "may make such order as it thinks fit.". The other available construction is that the words "may by such order confirm, reduce, increase or vary the assessment", areé not words of limitation but are facultative indications of the kinds of final orders which may be made. Support for the latter construction 1s provided by Australian Machinery and Investment Co. Ltd. v. Deputy Federal Commissioner of Taxation (1946) 8 ATD 81 where Latham CJ observed, at 92: "Section 199 of the Act provides that the court hearing the appeal may make such order as it thinks fit and may by such order affirn, increase, reduce or vary the assessment. In my opinion the initial words of this provision enable the Court to set aside an assessment." A similar view was expressed by Starke J. at 37 and by Dixon dg. who said, at 93: "The language of 5.199(1) appears to me quite general enough to empower the Court to make orders setting aside assessments whether for the purpose of directing re-assessment or in order to give effect to a determination that there is no liability to assessment. I see no reason for restricting the words 'such order as it' thinks fit' to the kinds of order specifically referred re tu ba im the sub-section, viz., seeders confirming reducing, iunmcreasing sr varying assessments. [t would be a misfortune if such a restriction were placed on the provision. For justice could not be done in some cases unless the Court could quash an assessment, and, in others, unless i1t could vacate an assessment and remit the question of the amount of the taxable aincome to the Commissioner for complete re-assessment." To similar effect, Williams J. observed, at 115: "Section 199 provides that the Court hearing the appeal may make such order as it thinks fit and may by such order confirm, reduce, increase or vary the assessment. It was contended that the initial generality of the section 1s limited by its subsequent explicitness, 50 that the jurisdiction of the Court is confined to confirming, reducing, increasing or varying the assessment. A casual glance at the Commonwealth Law Reports is sufficient to show that orders setting aside assessments have been frequently made. The power conferred upon the Court to make such order as it thinks fit is expressed in the most general terms and is clearly intended, in my opinion, to bestow upon it the most ample authority to mould its order to meet the Circumstances of any particular appeal. ' In Federal Commissioner of Taxation v. Offshore Oil (1980) 49 FLR 159 it was held by Franki and Lockhart JJ N.L. that a declaration by a Supreme Court on a preliminary question of law that it had jurisdiction to entertain certain taxation appeals, and an order as' to the costs of that question were "orders" within 5.200 of the Act. Deane J., however, doubted the correctness of that view saying at 164: "As vegards the question of the jurisdiction of this Court to entertain the appeals and -cross appeals, I entertain some doubt as to whether elther the declaration on the preliminary point or the order for costs made by the Supreme an order referred to in' Tax Assessment Act 1936 ('the this Court IT can see Was appeal Lies fo the Act. that the 'order referred to in Court 3.199 of the Income Act') from which an pursuant t6 5.200 of much force in the argument s.139 15 an order effectively disposing of an appeal to the Supreme Court. The other members of the court are, however, of the opinion that the court does have Jurisdiction to hear the appeals and cross appeals and both parties submitted that that view was correct. In unnecessary that I the question since I any event, bow to the views of the other of the court and deal with the substance cof these circumstances, it reach any concluded view consider that I should, 1s on in members the appeals and cross appeals." There was no counterpart of 5.199(1) ain 5.196 of the Act which, until its repeal, governed appeals or references to a Supreme Court from a Board of Review Sub-sections 196(3)(4) and "(3) An under this section Judge of the Court. (4) appeal does not appeal or reference Except as provided lie on a question of law. (5) simply provided as follows: to a Supreme Court shall be heard by a single unm sub-section (5), an from the decision of a Supreme Court constituted by a single Judge on an appeal or reference under this section. (5) The Commissioner or the taxpayer may appeal against a decision of a Supreme Court on an appeal or reference under this section - (a) by leave of the Federal Court of Australia, to that Court; or (b) by special leave of the High Court, to that Court." Whether an appeal Supreme Court on a preliminary question arising in an by the Commissioner under lay to this Court s.196(1) was considered by a from the decision of a appeal Full Court, in Federal Commissioner of Taxation v. Mantle Traders Pty. Ltd. (1980) 49 PLR 256 where Bowen CJ (with whom Franki and Brennan JJ agreed) after noting that a somewhat similar question arose in Federal Commissioner of Taxation v. Offshore 011 N.L. (supra), observed, at 258:- "The answer to the question in this case must turn on the interpretation of s.196(4) and (5). Section 196(4) by its reference to 'the decision ».. ON an appeal ... under this section' seems to point to the decision of the Supreme Court determining the appeal under s.136(1). Section 196(5), on the other hand, 15 general in its terms. It refers to 'an appeal against a decision of a Supreme Court onan appeal ... under this section which suggests 1t covers any decision of the Supreme Court on the appeal. If so, it would cover a decision ona preliminary question, such as has been given in the present Case, or an interlocutory order. But 5.196(4) says 'except as provided in sub-section (5)'. It might be argued that s.196(5) 1s limited, operating simply as an exception from 5.196(4). However, 5.196(4) 15 a prohibition. The words of exception were appropriate to lift the prohibition from s.196(5). This would appear to leave the scope of s.196(5) itself to be determined by the words used in that section. Since the words are general, it may be argued that its scope is general. In the result, though in absence of argument, my view as at present advised is that we should entertain the appeal." In our opinion, the better view in the light of the authorities is that s.200 should be taken as making appellable any order of a Supreme Court made in the exercise of the discretion conferred by s.199(1) to make such order as it thinks fit, and should not be confined to final orders. We are also influenced to favour the former construction by the consideration that, without it, a Supreme Court would have no axpress rower ta make orders dealing with procedural or other interlacutory 155ues arising in taxation appeals under 35.197, although clearly, on the authority of Federal Commissioner of Taxation v. Mantle Traders Pty. Ltd. (supra), it has such a power in respect of appeals or references coming from a Board of Review. It thus becomes necessary to consider whether an appeal to this Court from a decision of a Supreme Court on a procedural or other interlocutory issue is by leave or as of right. Mr. Merkel Q.C., for the Commissioner, contrasted 5.200 with the former s.196(5) and argued that the express requirement for leave of the Federal Court to pursue an appeal under 5.196, negatived any intention that leave should be required to pursue any appeal under 5.200. However, s.196 was concerned with an appeal from a Supreme Court on a question of law which had arisen at first instance before a Board of Review. It 15 therefore understandable that the legislature should be concerned that there be control of the opportunity for a review by this Court of a question which may have been twice litigated previously, even where the second litigation resulted ina final order. There would naturally be less concern about an appeal of the kind contemplated by 5.200 from a final order made after only one review of the Commissioner's disallowance of an objection. That is not to say that the draftsman of s.200 set out to confer on the Commissioner and a taxpayer an unfettered right of appeal ta this Court, even from procedural or interlocutory orders of a Supreme Court. The stronger inference, in our opinion, 15 that Parliament intended that appeals to the Federal Court under s.200 should be attended by whatever restrictions, conditions or procedural requirements might generally be made applicable by the Federal Court of Australia Act 15976. Sub-section 24(1) of that Act provides as follows: "24. (1) Subject to this section and to any other Act, whether passed before or after the commencement of this Act (including an Act by virtue of which any judgments referred to in this section are made final and conclusive or not subject to appeal), the Court has jurisdiction to hear and determine - (a) appeals from judgments of the Court constituted by a single Judge; (b) appeals from judgments of the Supreme Court of a Territory; and (c) in such cases as are provided by any other Act, appeals from judgments of a court of a State, other than a Full Court of the Supreme Court of a State, exercising federal jurisdiction." The following new sub-section was inserted by Act No. 72 of 1984: "CL1A) An appeal shall not be brought from a judgment referred to in sub-section (1) that is an interlocutory judgment unless the Court or a Judge gives leave to appeal." Accardingly, si tna view we favour, an appeal from the orders pronounced by Tadgell J. cn 22 and 29 ictober 1986 in respect of the present taxation appeal, 15 by leave af this Court. We are encouraged in this conclusion by a consideration of the legislative history of the provision of appeals under the Act to the High Court. Sections 37 and 38 of the Income Tax Assessment Act 1915 provided as Follows: "37.-(1.) A taxpayer who is dissatisfied with the assessment made by the Commissioner under this Act may, within thirty days after service by post of the notice of assessment, lodge an objection in writing with the Commissioner against the assessment stating fully the reason for the objection. (2.5 The Commissioner shall sconsider the objection, and may either disallow it, or allow 1t,either wholly or in part. (3.) The Commissioner shall give to the objector written notice of his decision on the objection. (4.) A taxpayer who 1s dissatisfied with the decision of the Commissioner, may, within thirty days after the service by post of notice of the decision of the Commissioner, ask the Commissioner to treat his objection as an appeal, and forward it either to the High Court, the Supreme Court, or a County or District Court of a State, or such other Court as is specified in that behalf by proclamation, as required by the taxpayer. (S.) When the appeal is to the High Court ora Supreme Court, 1t shall be heard by a = single Justice of the Court. (6.) An inferior Court of a State shall not have jurisdiction under this section unless it 1s constituted or presided over by a Judge authorized in that behalf by the Governor- General. (7.) If the assessment has been reduced by the Commissioner after considering the objection, the reduced assessment shall be the assessment appealed from. 38.-(1.) On the hearing of the appeal, the Court may make such order as it thinks fit, and may elther reduce or increase the assessment and its order shall be final and conclusive on all parties except as provided in this section. 12.) The costs of the appeal shall be in the discretion of the Court. (3.) On the hearing of the appeal, the Court may, if it thinks fit, state a case in writing for the opinion of the High Court upon any question arising i1n the appeal which in the opinion of the Court is a question of law. (4.) The High Court shall hear and determine the question, and remit the case with its opinion to the Court below, and may make such order as to costs of the case stated as it thinks fit. (5.) An appeal shall lie to the High Court, in its appellate jurisdiction, from any order made under sub-section (1.) of this section." The corresponding provisions in the Income Tax Assessment Act 1922-1925 were ss.50 and SIA which, so far as relevant, in the following terms: "SO.-(1.) A taxpayer who 15 dissatisfied with the assessment made by the Commissioner under this Act may, within forty-two days after the service by post of the notice of assessment, post to or lodge with the Commissioner an objection in writing against the assessment stating fully and in deta1l the grounds on which he relies, (2.) The Commissioner shall consider the objection, and may either disallow it, or allow it, either wholly or in part. were (3.5 The Commissioner shall consider the objection, and may either disallow it, or allow Lt, erther wholly or in part. (4.5 A taxpayer who 15 dissatisfied with the decision of the Commissioner, Assistant Commissioner or Deputy Commissioner may within thirty days after the service by post of notice of that decision - {a) in writing, request the Commissioner to refer the decision toa Board of Review for review; or (b) in writing, request the Commissioner toa treat his objection as an appeal and to forward 1t either to the High Court or to the Supreme Court of a State." "@DA.-l1l.. Where a4 taxpayer has, in accordance with section fifty of this Act, requested the Commissioner to treat his objection as an appeal and to forward 1t to the High Court or the Supreme Court of a State, the Commissioner shall forward it accordingly. (2.) The appeal shall be heard by a single Justice of the Court. (3.) A taxpayer shall be limited, on the hearing of the appeal, to the grounds stated in his objection. ... (5.) On the hearing of the appeal, the Court may make such order as it thinks fit, and may reduce, increase or vary the assessment. (6.) An order of the Court shall be final and conclusive on all parties except as provided in this section. ... {10.) The Commissioner or a taxpayer may appeal to the High Court, in its appellate jurisdiction, from any order made under sub-section (5.) of this section." By the Income Tax and 5o0cial Services Contribution Assessment Act 1936-1962 the right to appeal directly to a Court against disallowance by the Commissioner of a taxpayer's objection was governed by 35.197, 199 and 200 which provided: "197. Where, at the request of the taxpayer, the Commisz=toner has treated his chiection as an appeal and forwarded 1t tu the High Court or the Supreme Court of a State, the appeal shall be heard by a single Justice or Judge of the Court. 139.-11.) The Court hearing the appeal may make such order as it thinks fit, and may by such order confirm, reduce, increase or vary the assessment. The costs of the appeal shall be in the discretion of the Court. 42.) Every such order shall be final and conclusive except as hereinafter provided. 200. The Commissioner or taxpayer may appeal to the High Court in its appellate jurisdiction from any such order. The appellate jurisdiction of the High Court, to which a reference was preserved throughout that legislative history, was a concept expressly embodied in Part V of the Judiciary Act 1903 which, as in force until 1973, contained ss.34 and 35 in substantially this form: "34. The High Court shall, except as provided by this Act, have jurisdiction to hear and determine appeals from all judgments whatsoever of any Justice or Justices, exercising the original jurisdiction of the High Court whether in Court or Chambers. 35. (1) The appellate jurisdiction of the High Court with respect to judgments of the Supreme Court of a State shall extend to the following judgments whether given or pronounced in the exercise of federal jurisdiction or otherwise and to no others, namely: (a) Every judgment, whether final or interlocutory, which - (1) is given or pronounced for or in respect of any sum or matter at lssue amounting to or of the value of Three thousand dollars; or (2) involves directly or indirectly any claim, demand, or question, to ar respecting any property or any civil right amounting to or of the value of Three thousand dollars; or (3) affects the status of any person under the laws relating to aliens, Marriage, divorce, bankruptcy, or insolvency; but so that an appeal may not be brought From an interlocutory judgment except by leave of the Supreme Court or the High Court- (bs Any judgment, whether final or interlocutory, and whether ina civil or criminal matter, with respect to which the High Court thinks fit to give special leave to appeal: (c) Any judgment of the Supreme Court of a State given or pronounced in the exercise of federal jurisdiction nia matter pending in the High Court. (2) It shall not be necessary in any case, in order to appeal from a judgment of the Court of a State to the High Court, to obtain the leave of the Court appealed from." It is significant that ss.199 and 200 of the Act were amended to the form in which they are reproduced above by s.8 of the Income Tax Assessment Amendment (Jurisdiction of Courts?) Act 1976, which was passed in the same year and the same sessicn of Parliament as the Federal Court of Australia Act 1976, and the Judiciary Amendment Act No. 154 of 1976. The latter Act by s.6 inserted a new section 35 in the Judiciary Act, in subsktifution for that reproduced abuve. Co far as relevant ts a8) hls case, the new 5.35 contained the following "35. (1) The jurisdiction of the High Court to hear and determine appeals from - (a) judgments of the Supreme Court of a State, whether given or pronounced an the exercise of federal jurisdiction or otherwise; or (b) judgments of any other court of a State given or pronounced in the exercise of federal jurisdiction, whether in civil or Criminal matters, 15 subject to the exceptions and regulations prescribed by this section. (2) Except as provided by the succeeding provisions of this section, an appeal shall not be brought from a judgment, whether final or interlocutory, referred to in sub-section (1) unless the High Court gives special leave to appeal. (3) Subject to sub-section (4), an appeal may be brought as of right from a final judgment of a Full Court of the Supreme Court of a State given Or pronounced - (a) for the sum of $20,000 or upwards; or (bd) in any proceedings in which the matter in issue amounts to or 15 of the value of $20,000 or upwards or which involve directly or indirectly a claim, demand or question to or respecting any property or any civil right amounting to or of the value of $20,000 or upwards. (4) An appeal shall not be brought from a judgment referred to in sub-section (3) on a ground that relates to the quantum of any damages in respect of death or personal injury unless the High Court has given special leave to appeal on that ground. (5) The foregoing provisions of this section Mave effect subject to any special provision made by an Act other than this Act, whether passed before or after the commencement of this section, preventing or permitting appeals from the Supreme Courts of the States in particular matters." Sub-sections (3) and (4) were subsequently repealed by the Judiciary Amendment Act (No.2) of 1384 which amended sub-5.(2) to read: "An appeal shall not be brought from a judgment, whether final or interlocutory, referred to in sub-section (1) unless the High Court gives special leave to appeal." At all times since 19765 the appellate jurisdiction of the High Court to hear and determine appeals from this Court has been governed not by the Judiciary Act but by Part IV of the Federal Court of Australia Act 1976. Section 33 of that Act originally distinguished the cases 1n which an appeal lay as of right from a Full Court of this Court, from those in which special leave was required, by providing as follows: "(3) Except as provided by the succeeding provisions of this section, an appeal shall not be brought from a judgment of a Full Court of the Court unless the High Court gives special leave to appeal. (4) Subject to sub-section (5), an appeal may be brought as of right from a final judgment of a Full Court of the Court given or pronounced - (a) for the sum of $20,000 or upwards; or (b) in any proceedings in which the matter in issue amounts to or is of the value of $20,000 or upwards or which involve directly or indirectly a claim, demand or question to or respecting any property or any civil vight amounting to or of the value of 320,000 or upwards. (5) An appeal shall not be brought from a judgment referced tao in sub-section (4) on a ground that relates to the quantum of any damages in vespect of death or personal injury unless the High Court has given special leave to appeal on that ground." However, by the Federal Court of Australia Amendment Act 1984 which was passed in conjunction with the Judiciary Amendment Act (No. 2) 1984, sub-ss.(4) and (5) were omitted and the introductory exception in sub-s.i13) was amended to read "Except as otherwise provided by another Act ...". No right of appeal from an order of a Full Court of this Court pursuant to s.200 of the Act was conferred by the Act itself but it was recognized that such a right existed by virtue of 5.33 of the Federal Court of Australia Act. Hence, 5.200A was inserted in the Act by s.43 of the Jurisdiction of Courts (Miscellaneous Amendments) Act 1979 to provide: "An appeal does not lie froma decision of the Federal Court of Australia in a matter under this Part unless the High Court gives special leave to appeal." As a result of the amendments in 1984 to 5.33 of the Federal Court of Australia Act, s.200A of the Act now has no Practical operation. In our opinion, that legislative history argues stromgly in favour of the conclusion that s.200 of the Act as amended in 1976 was intended to entrust to the appellate jurisdiction of this Court, or alternatively by special leave of the High Court to the appellate jurisdiction of that Court, a review of an order made by the Supreme Court of a State on a so-called taxation appeal, but fo leave the conditions for the exercise of the appellate jurisdiction of this Court and any right of appeal from its exercise to the High Court to be defined by the Federal Court of Australia Act as in force from time to time. Mr. Merkel contended that the Statute Law (Miscellaneous Provisions) (No. 1) Act, 1984 which inserted sub-s.24(1A) into the Federal Court of Australia Act, was a later general Act which was not to be construed as cutting down the earlier special enactment to be found in s.200 of the Act. He referred to Kutner v. Phillips £18913 2 OB 267 where A.L. Smith J. observed, at 272: "Unless two Acts are so plainly repugnant to each other, that effect cannot be given to both at the same time, a repeal will not be implied, and special Acts are not repealed by general Acts unless there is some express reference to the previous legislation, or unless there 15 a necessary inconsistency in the two Acts standing together." However, on the construction which we have adopted of s.200 of the Act no question arises of its repeal or abrogation by the insertion of sub-s.24(1A) in the Federal Court of Australia Act. Tt 1s true that sub-s.24(1A) affects the operation of s.200 of the Act, but that was no more than was contemplated when s.200 was amended to permit resort to the appellate jurisdiction of this Court as, we consider, 1 might be defined from time to time. Accordingly, the Commissioner cannot bring an appeal against an interlocutory judgment such as those given by Tadgell J. on 22 and 29 October 1986, unless this Court or a Judge of this Court gives leave to appeal. We turn now to consider whether the Commissioner should have leave to appeal in the present case. The approach to he taken by an appellate court to whether it should grant leave to appeal from an interlocutory order 18S reasonably well settled. However, various formulations of the appropriate test have been expressed in different authorities. In Commissioner of Taxation v. Nestle Australia Limited (unreported, 5 November 1986) a Full Court of this Court (Bowen C.J., Lockhart and Sheppard JJ.) adopted, the following passage from the joint judgment of Gibbs C.J., Aickin, Wilson and Brennan JJ. in Adam P. Brown Male Fashions Pty. Ltd. v. Philip Morris Inc. (1981) 148 CLR 170, at 177: "Nor 1s there any serious dispute between the parties that appellate courts exercise particular Caution in reviewing decisions pertaining to practice and procedure. Counsel for Brown urged that specific cumulative bars operate to guide appellate courts in the discharge of that task. Not only must there be error of principle, but the decision appealed from must work a ubstantial injustice to one of the parties. The PPOSing view a5 that such criteria are to be xpressed disjunctively ... For ourselves, we believe 1t to be unnecessary and indeed unwise £ lay down rigid and @xhaustive critectia. The Circumstances of different cases ar2 infinitely varicus. We would merely repeat, with approval, the oft-cited statement of Sir Frederick Jordan in In re the Will of F.B. Gilbert (dec.i (1346) 46 S.R.(N.S.W.) 318 at p. 323: mba ».. I am of opinion that, ... there is a material difference between an exercise of discretion on a point of practice or procedure and an exercise of discretion which determines substantive raghts. In the former class of case, 1f a tight rein were not kept upon interference with the orders of Judges of first instance, the result would be disastrous to the proper administration of justice. The disposal of cases could be delayed anterminably, and costs heaped up indefinitely, if a litigant with a long purse or a_ litigious disposition could, at will, in effect transfer all exercises of discretion in interlocutory applications from a Judge in Chambers to a Court of Appeal." We were veferred also to Niemann _v. Electronic Industries Ltd. £19781 V.R. 431 where Murphy J., with whom McInerney J. agreed, suggested that for leave to be granted, the order in respect of which it is sought must be seen clearly to be "attended with sufficient doubt", and, if wrong, to work substantial injustice. See also B.H.P. Petroleum Pty. Ltd. v. Oi] Basins Ltd. €19853 V.R. 756 at 758 and 762. Without regarding that formulation as an exhaustive test to be applied to all cases, we believe it useful to ask first whether it has been clearly demonstrated that Tadgell J's exercise of discretion was attended with sufficient doubt' toa warrant this Court re-examining the considerations ta be taken into account. The first suggested error, into which Mr. Markel argued his Honour had been led, was to fail to recognize that the Commissioner had a right to discovery by virtue of 0.32 er.9 and 10 of the High Court Rules which are made applicable to s0-Called taxation appeals by 0.65 err.1 and 2 of the High Court Rules. Order 65 rr.1l and 2 provide: "(1) This Order applies to an appeal to the High Court or to the Supreme Court of a State or Territory under or pursuant to a law of the Commonwealth or of a Territory dealing with the assessment of taxation and to questions referred under such a law to the High Court. (2) Subject to this Order and to any law of the Commonwealth, the provisions of the other Orders of these Rules apply, so far as is practicable, to proceedings to which the last preceding rule applies." Order 32 rrvr.9 and 10, ain turn stipulate that: "€9) A party May serve a notice in accordance with the form numbered 30 in the First Schedule upon another party to a proceeding requiring him to make discovery on oath of the documents which are or have been in his possession or power, relating to a matter in question in the proceeding. (10) Where a party 1s served with a notice for discovery - Lo m (a) that party; or (b) where that party 15 a body politi or corporate, or any other body o persons empowered or allsawed by la to sue or be sued whether in its own name or in the name of an officer or other person, the secretary or other proper officer, agent or servant of the body, shall, within fourteen days after service of the notice, make an affidavit in answer to the notice." Reference was also made to 0.1 fr.5 inwhich "party" and "parties" are defined to include, as well as the plaintiff and the defendant: - (a) a person not originally a party against whom a counter-claim is set up or who has been served with notice to appear under any of these Rules; and tb) a person served with notice of or attending a proceeding although not named on the record or in the process;" Counsel for the Commissioner relied strongly on the fact that 0.65 of the High Court Rules came into operation on 1 January 1953, shortly after judgment was given by the High Court in George v. Federal Commissioner of Taxation (1952) 86 CLR 183. In that case the Court ina joint judgment upheld a decision of Kitto J. refusing to order the Commissioner to furnish particulars of the basis on which the taxpayer had been assessed on two additional sums of money, and of internal processes by which the assessment was arrived at. At first instance, Kitto J., at 130 observed of the first part of the request for particulars:- "T was not referred to any authority on the point, and so far as I know there 1s none. But an analogy may be found in the cases in which the courts in England have considered applications by piaintiftfs upon whom lies the onus of proving a negative, for particulars from defendants who have put in assue the plaintiff s negative allegation. The principle laid down is that if it 15 clear to the court, either from the nature of the case or from the admission of counsel or otherwise, that the defendant intends under his denial of the negative, to set up an affirmative case, particulars of the defendant's case may be ordered; but not otherwise (Pinson v. Lloyds and National Provincial Foreign Bank Ltd. (1941) 2 KB 72 at p.80; Duke's Court Estates, Ltd. v. Associated British Engineering Ltd. (1948) Ch. 458; cf. Weinberger v. Inglis (1918) 1 Ch.133.} So, if in this matter the commissioner were to admit that he intended to set up a case that the additional income upon which he has assessed tax was derived from a particular source, I should think that he ought to give particulars to enable the appellant to meet that case. But the commissioner has made no admission and there is nothing which could entitle me to infer that he has such an intention. All that appears is, as I have said, that the appellant is put to the proof of his negative case. In my opinion it would not be consistent with the authorities I have cited, or with the commonsense of the situation, to erder particulars. If the commissioner s case at the hearing of the appeal develops upon lines which the appellant cannot fairly be expected to be ready to meet, the presiding Judge will be in a position to ensure that no injustice results." Fullagar J. was a party to the joint judgment on the appeal from Kitto J. but went on, at 207, to deliver the following addendum: - "TI wish, however, to add for myself that, in my opinion, apart altogether from any question of ran) burden of proof, the application for 'particulars was rightly rejected by Kitto J. Tt was not really an application for particulars at all. The subject matter of the demand = for information was rather subject matter for interrogatories, and I can see no warrant for ordering interrogatories to be answered ina case of this type, even if Iam to assume that the Court has power to make such an order, which I doubt. It 1S common practice, in the Court lists and in the Law Reports to entitle a taxation appeal as if 1t were a proceeding between a named taxpayer and the Commissioner of Taxation. But the Commissioner 1S only nominally a 'party' to the proceedings. The proceedings are really proceedings between Crown and subject. A similar position exists under the Patent Act 1352 and the Trade Marks Act 1905-1948. The substance of the position in taxation cases is not affected by the fact that the Commissioner is given eo nomine a right of appeal from decisions of the Board of Review. The Commissioner 1s an officer who, in the performance of his statutory functions, does acts which prima facie create am obligation as between the Crown anda particular subject, and the statute provides means whereby the subject may test before a court or a board the question whether the Commissioner has acted according to law. In proceedings before court or board the Commissioner's acts are called in question, but he 1s in no real sense a party. This does not mean that he is not, in many respects, subject to orders of the court, but it does mean that certain orders which are quite appropriate as between parties toa an action are quite inappropriate as between an appellant taxpayer and the Commissioner." That was the passage from which, as we have already noted, Tadgell J. drew support in the present case. We are not persuaded that the insertion of 90.65 in the High Court Rules was specifically directed to supplying some procedural deficiency in respect of taxation appeals which was perceived to exist asa result of the judgments in George's Case. However, we accept that the effect of the insertion of 0.65 was to lay down for the hearing of a taxation appeal by the High Court or the Supreme Court of a State or Territory, a procedural code which incorporates by reference other Orders of the High Court Ruies by making them apply "so far as 15 practicable". Nor do we consider that a taxation appeal 15 a suit to which the Commonwealth is a party within the meaning of 5.64 of the Judiciary Act 1903, which provides: "In any sult to which the Commonwealth or a State is a party, the rights of parties shall as nearly as possible be the same, and judgment may be given and costs awarded on either side, as in a suit between subject and subject." Section 2 of the Judiciary Act provides that: "In this Act, unless the contrary intention appears - Suit' includes any action or original proceeding between parties; 'Cause' aincludes any suit, and also includes criminal proceedings; 'Matter' includes any proceeding in a Court, whether between parties or not, and also any incidental proceeding in a cause or matter." Although it is clear that the Commonwealth may be a party to a suit, it is equally clear that not every cause or matter in which the Commonwealth or some person representing the Commonwealth is involved, is a suit. We prefer to regard an appeal to a specified Supreme Court pursuant to 5.187(1)'pb) Lis ve of the Act as a proceeding Su eneris to which any Particular provision of the High Court Rules will be applicable, so far as the substance of that provision and the nature of the proceeding makes such application practicable. The proceedings in Naismith v. McGovern (1953) 30 CLR 336 to which Mr. Merkel referred us, were not of that kind but were by action commenced in the High Court by the Commissioner of Taxation for a declaration that the defendant had been guilty of offences under the Act, and for an order for the payment of penalties in respect of the alleged offences. Accordingly, the High Court (Williams, Webb, Kitto and Taylor JJ) was able to say, at 343: "Section 222 of the Assessment Act provides that taxation prosecutions are proceedings by the Crown for the recovery of pecuniary penalties under the Assessment Act. Such prosecutions are original proceedings in this Court. They proceed in accordance with the usual practice and procedure of the Court in civil cases. We can see no reason why 5.64 of the Judiciary Act should not apply to such proceedings." Nor do we consider that Bailey v. Federal Commissioner of Taxation (1977) 136 CLR 214 supports the view that discovery is now available in a taxation appeal as of right by virtue of 0.65 rr.l and 2 of the High Court Rules. That case affirmed the existence of a discretion to order particulars in a taxation appeal. However, in none of the judgments 15s there any suggestion that George v. Federal Commissioner of Taxation (supra) has been overtaken by some change in the munteat of the Act and the Rules pursuant fa whith taxation appeals have to be resolved. It follows, therefore, that whether the taxpayer should be ordered to provide particulars or afford discovery to the Commissioner was a matter to be resolved in the exercise of his Honour's discretion. Accordingly, as Mr. Shaw 0.C. for the taxpayer submitted, if this Court were to review that exercise of discretion, it would be bound to apply the principles laid down in such cases as House v. The King (1336) 55 CLR 499 and Mace ov. Murray (1955) 92 CLR 370. In the former case 1t was observed in the joint judgment of Dixon, Evatt and McTiernan JJ. at 504: "The manner in which an appeal against an exercise of discretion should be determined is governed by established principles. It 15 not enough that the judges composing the appellate court consider that, 1£ they had been in the position of the primary judge, they would have taken a different course. It must appear that some error has been made in exercising the discretion. If the judge acts upon a wrong principle, if he allows extraneous or irrelevant matters to guide or affect him, if he mistakes the facts, 1f he does not take into account some material consideration, then his determination should be reviewed and the appellate court may exercise its own discretion in substitution for his 1f it has the materials for doing so. It may not appear how the primary judge has reached the result embodied in his order, but, 1f upon the facts it is unreasonable or plainly unjust, the appellate court may infer that in some way there has been a failure properly to exercise the discretion which the law reposes in the court of first instance. In such a case, although the nature of the error may not be discoverable, the exercise of the discretion 1s reviewed on the ground that a substantial wrong has in fact occurred." +1. We have already indicated our view that his Honour did not act on a wrong principle in concluding that the Commissioner was not entitled, as of right, to a general order for discovery. However, the fact that the application for discovery was made first and was pressed as if some such absolute entitlement existed may have led the learned judge at first instance to rely on irrelevant or extraneous matters, or to have disregarded or given insufficient weight to same material considerations. The difficulty which was created for his Honour because the application for discovery was argued first and without reference to the Commissioner's desire for particulars of taxpayer's objection is illustrated by the criticism which Mr. Merkel directed at that passage in his Honour's reasons for judgment of 22 October 1986 where it was observed: "It is common ground that the issues have been sufficiently defined here by means of the appellant's notice of objection, on the one hand, and the notice of particulars ofr the Commissioner s grounds of disallowance of it on the other." The basis of that observation was a submission by Senior Counsel for the Commissioner who 1s recorded as saying: "T should say, Your Honour, that the notice of objection 15S very detailed and I - the particulars provided for the Commissioner clearly define the issues and the ambit of those issues for the points of nutice of ohjyection we would submit, identifying what purpose of discovery, in provide the issues any ace in other claim and points vf defence, being and the particulars do difficulty respect which discovery 15 required to be made." words the not, with of The Commissioner's application for further particulars of the notice of objection, although an application had been foreshadowed on 23 June 1986, was not October 1986 after his Honour had on 22 judgment on the application for discovery. [In the second hearing before his Honour, Senior Counsel for for discovery made until 29 October given the course of' the Commissioner referred to his earlier submission quoted above, and went on to say: "What we were identifying, Your the definition of the discovery is defined, but, a hearing upon those affidavits and find, Your Honour, 18S that there identification anywhere of each unit of property in respect of which the deductions are claimed, and nor Honour, aS a consequence, respect of each unit construction or acquisition of them. Your Honour will recall it chemical plant that we are critical to the issues units of relevant property. 15 a property, or We would the say whilst 1t court as to what are the units Honour, issues for the purpose Your Honour, come to look at the affidavits and the threat upon notice of objection and the particulars, what 1s 1s clearly a matter 1s that of we of the we not an eligible when allowable is there, contracts defined of property either for your in the complicated concerned with, is the definition of and the eligible for of property at the end of the day, the taxpayer has a case to put which may be many alternative cases, but at the worst, it should be asked to identify each unit of property or eligible property referred ta in 1ts objection." Netwithstanding that inversion of the logical sequence of the applications for particulars and discovery, his Honour, as indicated by the second passage which we have quoted above from his judgment of 29 October 1386 was, at first, disposed to accede to the application for particulars of each contract referable to the acquisition or construction of eligible property. However, he was deflected from that course by the indication given on behalf of the taxpayer that particulars of each contract on which it intended to rely could be discerned from the affidavits which had been filed on its behalf and the exhibits thereto. The taxpayer's affidavits and exhibits occupied almost 800 pages of the present appeal books. To say that, because within that mass of material can be discerned the only contracts on which the taxpayer relies, "no sensible purposes would be served by further particularisation" is, with respect, to misapprehend the function of particulars. That function, in the present context was described in several passages in the judgments of the High Court in Bailey v. Federal Commissioner of Taxation (supra). Gibbs J. observed, at 219: "The facts in a case arising under s.260 are not necessarily all within the knowledge of the taxpayer. However, it is a misapprehension to think that the only function of particulars is to reveal to a party facts of whose existence he 1s unaware. As I have indicated, particulars have the important function of informing a party of the nature of the case he has to meet and of limiting the issues of fact to be investigated by the court." To similar effect Mason J. at 220, pointed out that: "There 1s therefore no foundation for the notion that the Commissioner stands apart from ordinary litigants in some special position in relation to the giving of particulars. Like any other litigant he may be ordered to give particulars in an appropriate case, that 1s, when they are required so that the other party to the litigation, and for that matter the court itself, may be acquainted with the nature of the case that is intended to be presented, so that the issues to be determined may be defined. To conclude otherwise would result not merely in injustice to the taxpayer, who will remain in doubt as to the Commissioner's case until it 1s presented at the hearing, but also in unnecessary preparations and in a hearing of unnecessary length as the taxpayer endeavours to deal with matters on which, as it may subsequently transpire, the Commissioner is Placing no reliance whatsoever." Jacobs J. also emphasised the role which particulars can serve in defining the questions at issue between parties saying, at 2721: "But rules or practices as to particulars must be sufficiently flexible to allow all parties to an action or matter to meet with necessary evidence and without delay to court processes questions which may be raised at the hearing. Their purpose is to concentrate and define the issues of fact and to prevent surprise and consequent delay. At the same time it must be borne in mind that particulars do not constitute a pleading and do not ordinarily define issues of law. They must 4. tend ts advance the clear and speedy determin- ation of all the questions which fall bo determined Csicl. They are not anet in which the ready and comprehensive determination of the ultimate issue can become enmeshed and delayed. Although particulars are essentially particulars of fact and not of law, when there are no sufficiently defined issues ut 15 not always possible to obtain particulars of facts without first ascertaining whether those facts will be relevant to questions which may be raised." Aickin J's. treatment at 227 of the same matter can be paraphrased to point cogently to the need for appropriate particulars of the taxpayer's notice of objection in the present case. His Honour said: "There 15 nothing in the policy of the Act nor in general considerations of policy to require that the Commissioner should not inform the appellant prior to the commencement of the hearing of those details so that the case may proceed in an orderly and comprehensible manner. It is not in the interests of the proper administration of justice that, when the matter comes before the court, the appellant should have to speculate about, and adduce evidence to negate, every possible kind of agreement or arrangement and avoidance which the imagination of his advisers can conjure up. Such a process is not merely time-wasting but is likely to obscure the real issues. It is mo doubt possible that in the course of the evidence facts may emerge which were not previously known to the Commissioner and which suggest that there was some contract, agreement or arrangement other than that which he had previously supposed existed and which would support the actual assessment, but that is a situation which can readily be cured by amendment and it cannot be doubted that the Commissioner would in those circumstances be permitted to amend his particulars even though he would again have to specify the details of the arrangement which he was then alleging." Of the request for particulars of each unit of eligible property to which the taxpayer may point, Tadgell J., as appears from the first passage quoted above from his judgment of 29 October 1386, considered that the task of identifying the unit or units was ultimately one for the Court, perhaps after taking into account conflicting expressions of opinion. That 1s undoubtedly true. However, the truth of that proposition does not entail the consequence that no sensible or useful purpose would be served by requiring the taxpayer to give particulars of each item or collection of items which it contends constitutes a unit of eligible property for the purpose of its objection. Even if such a requirement were to elicit a mumber of alternative formulations identifying units of eligible property, the parties and the Court would at least have a finite number of specific contentions on which to focus. The passages from Bailey's Case which we have quoted make clear that particulars may be ordered 1n an appropriate case which identify those questions that the party to whom the request for particulars 1s addressed seeks to raise. Specifically, in the present case, it seems to us, to paraphrase the passage from Aickin J.'s judgment which we have just quoted, that it is not inthe interests of the proper administration of justice that the Commissioner should have to speculate about, and be prepared to cross-examine the taxpayer's witnesses upon, every possible permutation and combination of units of eligible property which the imagination of his advisers can conjure up, after digesting the large body of affidavit material ts which his Honour referred. It will be apparent, from what we have said so far, that we are persuaded that his Honour was led into an error which caused the exercise of his discretion to order particulars of the taxpayer's objection to miscarry. We are also satisfied that the consequences for the continued litigation of this very substantial taxation appeal are sufficient to overcome the reluctance, for the reasons indicated in Adam FP. Brown Male Fashions Pty. Ltd. v. Philip Morris Inc. (supra) of an appellate court to interfere with an exercise of discretion on a point of practice or procedure. However, we believe that the same considerations do not require, at this stage even a limited order for discovery in favour of the Commissioner. In forming that belief we have assumed that any documents to which particulars which we propose to order the taxpayer to give will refer, have been exhibited to one or other of the affidavits already filed on its behalf, or that copies of them have otherwise been obtained by the Commissioner. Should that assumption prove unfounded, an application for appropriately lamited discovery 48. Or inspection can be made pursuant to the liberty to apply which we fcropose te reserve. Accordingly, we grant leave to appeal, dismiss appeal against the order of "2 October 1986 and allow appeal against the order of 29 October 1986. In lieu of latter order we give the following directions: 1. That the Appellant taxpayer within 60 days of this furnish in respect of sub-paragraphs 6(d) and (e) 7(d) and (e) of the grounds set forth in its notice objection dated 7 April 1983, particulars - th wo the the day and of (a) identifying each new unit of eligible property referred to therein, including each alternative identification of a unit of eligible property, on which the taxpayer relies; (b) specifying each contract for the construction or acquisition of each such unit of eligible property, and identifying each document, conversation or other matter which is said to constitute the same or from which the same is said to be implied. 2.
