MOTORS PROPRIETARY LIMITED Appellants AND : TRADE PRACTICES COMMISSION AND RONALD MOORE BANNERMAN Respondents CORAM : Brennan, Keely and Fisher JJ. 21 August 1980 THE COURT : This case concerns the validity, effect and operation of notices to the applicants purportedly given under the powers conferred by s.155 of the Trade Practices Act 1974 (Cth.) by Mr. Bannerman, the second respondent as chairman of the Trade Practices Commission, the first respondent. It comes on appeal from a judgment of Smithers J. who traced the course of the litigation im his reasons for judgment: " On 28 July 1978 the Chairman of the Trade Practices Commission (the Chairman) purported to issue a notice under s.155(1) of the Trade Practices Act (the Act) toa number of companies who may be called collectively if not entirely accurately "the Ford dealers". That notice required each of the companies to furnish information to the Trade Practices Commission (the Commission) by 28 August 1978 as requested aun the first Schedule to the notice and to produce the documents described in the second Schedule to the Notice. A number of recipients of the notice issued applications under s.163A of the Act for declarations that for varlous reasons the notices were invalid. At the request of the Commission and the Chairman, the Ford dealers not opposing, I stated a case for the Full Court raising questions concerning the validity of the notices and the obligations of the companies thereunder. On 28 March, 1979 the Full Court answered the questioms... In general the answers given by the Pull Court do not in any way lend aid to the Ford dealers' application under s.163A. " The notices were given to the respective respondents in a common form, and the terms of each notice appear in the following example: " NOTICE UNDER SECTION 155 Pursuant to section 155 of the Trade Practices Act 1974 (hereinafter referred to as 'the Act'), I, RONALD MOORE BANNERMAN, Chairman of the Trade Practices Commission, having reason to believe that Col, Paige Ford Pty.Ltd.

" Section 156 of the Act confers power to inspect, to take possession of or to take copies of a document produced in pursuance of a notice under s,.155. The case stated by Smithers J. was heard by a Full Court, constituted by Smithers, Franki and Northrop JJ. (Melbourne Home of Ford Pty.Ltd. & Ors v. Trade Practices Commission and Anor. (1979) ATPR 18080). The Full Court declared, inter alia, in answer to questions 1 and 3 in the stated case, that a notice given under s,155 may lawfully require a company to which it 1s directed to answer questions, provide information or produce 14. documents which might tend to expose it to a penalty under ss.45 and 76 of the Act; and that such a notice may lawfully be directed to a company itself suspected (by the Trade Practices Commission or the person giving the notice) of a contravention of the Act. That Court, by a majority (Franki and Northrop JJ) declined to answer certain other questions relating to the justiciab1lity of the Chairman's reason to believe the matters upon which his power to 1ssue a notice under s.155 depends. The reasons which led their Honours to decline to answer these questions were consonant with the reasons for judgment of the Full Court in the later case of W.A,Pines Pty.Ltd. v. Bannerman (unreported W.A.3 and 4 of 1980, 27 June 1980). When the application went back for hearing before Smithers J. after the stated case was disposed of, the applicants did not pursue a challenge to the Chairman's power to issue a notice to the applicants under s.155. The attack upon the notice before Smithers J. was based on the terms of the notice itself, and that attack was pursued before us upon the grounds that the notice is so wide, irrelevant, burdensome and oppressive that the notice lay beyond the power which s.155 conferred upon the Chairman. This attack had been raised in one of the questions (question 4) in the stated case, but the parties had not pressed for an answer to the question before the Full Court. They left 1t until Smithers J. sat to dispose of the application. His Honour, after giving careful consideration to the submissions made by counsel who then appeared for the applicants, dismissed the application (save in a minor and now immaterial respect). The applicants were ordered to pay four-fifths of the costs. The notice of appeal from the judgment of Smithers J. does not on its face raise any issue which was disposed of by the Full Court. Before Smithers J., as hts Honour observed, counsel who then appeared for the applicants "did not suggest that I could or should disregard the answers of the Full Court." Before this Court, however, counsel for the applicants sought again to agitate questions 1 and 3 though he frankly recognized the difficulties in doing so. He wished to keep those issues alive in the event of a further appeal, and submitted that the Full Court's declaration had been given effect by the final judgment of Smithers J. against which the appeal had been brought. We declined to allow the questions to be raised again on this appeal. The argument on questions 1 and 3 before the Full Court was calculated to procure a final determination upon the issues of law set aut in those questions: the proceedings before the Full Court were not some interlocutory step in the vrosecution of the application. 16. The Full Court, in answering questions 1 and 3, was no doubt exercising original, not appellate, jurisdiction, but the authority of a Full Court 1s not thereby diminished. It is unthinkable that, after questions of law arising 1n litigation have been submitted to a Full Court for determination in order to guide and govern the conduct of the litigation, the authority of the answers given by the Full Court should again be canvassed before another Full Court merely because the latter Full Court is exercising appellate jurisdiction. The answers are clearly the final determinations of the Federal Court upon the issues in controversy to which the answers relate. Accordingly, although no factual issue 1s in question, it may be said conveniently though loosely that each of the issues determined by the Full Court is res judicata. None of those issues can be reopened in this litigation except by appeal to the High Court of Australia (cf. In Re Waring; Westminster Bank v. Burton-Butler [1948] 1 Ch.221 per Jenkins J. at p.227). 'They were not to be reopened before us. Having regard to the course which the proceedings had taken, Smithers J. was entitled, and indeed bound, to consider the ultimate challenge to the Chairman's power to give the notices to the applicants, on the footing that none of the applicants was entitled to refuse to furnish information or to produce documents merely because that applicant was suspected of contravening s.45 or because compliance with the notice might tend to expose it to 17. a penalty. This Court is bound to approach the challenge to the validity of the notice upon the same footing. The course which the litigation has thus far taken narrows the issues for consideration by this Court. Ordinarily, when a question arises as to the validity of a s.155 notice issued under the first limb, three questions fall for consideration: (1} whether there 1s a "matter that constitutes, or may constitute, a contravention"; (2) whether the Commission, the Chairman or the Deputy Chairman (as the case may be) has reason to believe that the person to whom the notice is given "is capable of furnishing information, producing documents or giving evidence relating to" that matter; and (3) whether the information required to be furnished, the documents required to be produced or the evidence required to be given (as the case may be) relates to that matter. The first two of these questions are material to the existence of the power to issue a notice, the last to the manner of its exercise. Only the last question falls for determination in these proceedings, namely whether the Chairman has required each of the applicant companies to furnish information other 18. than documents relating to a matter that constitutes or may constitute a contravention, the "matter" being in each case: "that the company has given effect to a provision of an arrangement or understanding between the company and other corporations which has the purpose, or has or is likely to have the effect, of fixing, controlling or maintaining the prices for Ford spare parts supplied by those corporations, in competition with each other, to motor vehicle body repairers in Melbourne." If the information to be furnished or the documents to be produced in accordance with the notice respectively answer the description of "information relating te" or "documents relating to" the matter specified in the notice, the Chairman's requirement lies within the power which s.155 confers upon him. Provided the necessary relationship exists between the matter and the information or documents required, the notice is not open to objection on the ground that it is burdensome to furnish the information or produce the documents. As Bowen C.J. said in Riley McKay Pty.Ltd. v. Bannerman (1977) 31 F.L.R.129 at p.136: " It is not, I think, a good ground of objection to a notice under s.155 that it is burdensome or oppresSive. It is clear that when such a notice 1s given, the answering of it may involve the recipient in considerable work and expense. This, in itself, may constitute a kind of penalty whether or not there is ultimately found to have been a contravention. The legislation assumes that the public interest necessitates this. No doubt in practice, the commission will administer the Act in such a way as not to impose upon a person or company a burden completely disproportionate to the value to the commission of the information sought. " 19. In the case of a matter that may constitute a contravention, the Chairman may not know the constitutive facts of a contravention (if there has been one) and he may ultimately ascertain that there has been no contravention in the conduct or transaction which he is investigating. Because his attention has been drawn to a particular act or transaction which warrants 1nvestigation and because he has reason to believe that the person to whom the notice 1s given is capable of furnishing information relating to the matter under unvestigation he is engaged in a function of investigation, not in a task of proving an allegation. The power conferred by s.155(1) is in aid of that function and is a power which authorizes enquiries both wide 1n scope and indefinite in subject matter. It 1s an investigative power which 1s under consideration here and 1t is not possible to define a priori the limits of an investigation which might properly be made. The power should not be narrowly confined. In the present case, the investigative power of the Chairman 1S being exercised in an investigation into a matter that may constitute a contravention of s.45. Proof of a contravention of that section often depends upon circumstantial evidence. Section 45 1s itself expressed in general terms, and when an investigation into such a matter commences with littie 1nformation, the range of enquiries may need to be broad rather than specific. There is no 20. analogy to be made with interrogatories 1n litigation. Rules which are entirely appropriate to limit discovery with respect to issues defined by pleadings provide no sure guide to the Manner of exercise of a power to ascertain facts which may or May not result in litigation. The investigative power may properly be exercised by enquiring into the existence of facts which do not themselves constitute a contravention or deny the possibility of a contravention. The power may properly be exercised to ascertain facts which may merely indicate a further line of enquiry, or which may tend to prove circumstances from which an inference can be drawn as to the existence of other facts which have a more immediate and proximate relationship to the matter under investigation. The width of the power and the possibility of its abuse both justify judicial examination of an allegation that the power is used to produce an undue burden or oppression, and render that examination difficult to perform. The necessity for the jurisdiction, and the problems of exercising it are well reflected in what Ackner J. said in Clinch v. Inland Revenue Commissioners [1974 ]1 Q.B.76 at pp.91,92: The statutory authority in this case 1s in effect to ask questions - to require such particulars as the commissioners think necessary - for the purpose of the chapter dealing with the transfer of assets abroad. The particulars are sought of the intermediary in order that he may be used as a stepping-stone towards obtaining the more detazled information required by the commissioners to enable them to decide whether or not, 1n their opinion, tax has been unlawfully avo1lded. The information which they require 1s such as to give them a shrewd idea of the 21, relationship between a taxpayer and a foreign company, partnership, trust or settlement. Accordingly, 1f the particulars sought went substantially beyond that which was required for this purpose, so that they could be properly described as unduly oppressive or burdensome, I have no doubt that a court would be entitled to intervene, and declare the notice invalid. One of the vital functions of the courts is to protect the individual from any abuse of power by the executive, a function which nowadays grows more and more important as governmental interference increases." The Court cannot undertake the task of determining the way in which an investigation should be carried out, for that 1s a task which the legislature has confided to the Commission, the Chairman or the Deputy Chairman, The Court's jurisdiction is not to set the course of an investigation but to call a halt if it is shown that the investigation exceeds the powers conferred, Short of that point, the protection of the corporate citizen from harassment rests 1n the good sense of the repository of the power. To say that an undue or oppressive burden is imposed by a notice is not legally significant unless what is Meant is that the powers conferred by s.155 have been exceeded in the particular case. An excess of power may appear if the requirement for information or documents is couched in such wide and general terms that a proper exercise of the investigatory power could not support the requirement in question, This 1s but a 22. particular application of the general principle that the exercise of a discretionary power must be reasonably capable of being regarded as related to the purpose for which the power is conferred (see, e.g., Allen Commercial Constructions Pty.Ltd. v. North Sydney Municipal Council (1970) 123 C.L.R. 490). If the requirement expressed in a particular notice is reasonably capable of being so regarded, that ground for alleging an excess of power fails. It was argued that the sanctions for non-compliance with a s.155 notice necessitated a higher degree of precision in the language of the notice than might otherwise be the case, but in truth the sanction does not affect the dimensions of the power. To the extend to which specificity is required in a notice, 1t 1S required because of the limits of the power conferred by s.155, not because of the sanction imposed for failure to respond to a notice issued in the due exercise of the power. A particular objection to the width of the notice in the present case was founded on the lack of territorial specificity in the notice. It was said that questions in Schedule I might relate to conduct whach occurred outside the territorial limits to which the provisions of the Act extend, or to which the contravention or possible contravention under investigation related. Clearly enough, the "matter" specified 23. in the notice related to the price of Ford spare parts supplied to motor vehicle body repairers in Melbourne, and 1t was conceded that the conduct of Australian corporations wherever occurring which had effect in a market so defined might properly be a matter for investigation (see especially ss.5 and 45(3)). The body of the notice does not refer to that market, and it was submitted that a recipient of the notice could be asked to respond to enquiries with respect to overseas sales, for example. In reply, it was asserted that each of the applicants, according to an inference to be drawn from their names, waS a company carrying on business in the suburbs of Melbourne and that it was fanciful to conjure up foreign activities as illustrative of the width of enquiries said to ke embarrassingly non-specific and excessive, The argument must be evaluated according to the Meaning which the notices would convey to the recipient. The notices seek the furnishing of commercial information, and the production of documents relating to the matters in respect of which information 1s sought. Notices are to be reasonably, not preciously, construed and the terms used in notices will ordinarily take their meaning from the commercial circumstances in which the notices are given. If, in the circumstances in which an applicant was trading when 1t received the notice, the notice did not convey a requirement which lay within the power conferred by s.155, 1t was open to that applicant so 24, to show. But in the absence of that evidence, the requirements are to be construed as relating to the matter specified at the beginning of the notice, that is, as relating to conduct which has effect in the Melbourne market for Ford spare parts. So construed, each of the questions asked (save those parts which are not relevant to this appeal) appear to refer to the possible conduct of the company to which the notice 1s addressed in respect of a possible contravention by 1t of s.45 in the manner specified at the beginning of the notice. There is nothing to show that the information and documents sought by the notices were not required to ascertain whether a contravention of the kind specified in the notice had occurred, The power was therefore validly exercised, The appeal should be dismissed with costs, I certify that this and the preceding 23 pages are a true copy of the Reasons for Judgment herein of the Court.
