44 His Honour was there speaking of information adverse to the interests of those concerned upon which the decision-maker proposed to rely, believing it to be relevant, credible and significant. These passages do not support the appellants' submission that the rules of natural justice require them to have access to all material bearing on the subject-matter of the hearing within the possession of the ASIC (or in some way considered by officers of the ASIC, although not by Mr Malinaric). There is, moreover, no support for the proposition for which the appellants contend in such cases such as Boucher v ASC (1996) 71 FCR 122, Laycock v Forbes (1997) 25 ACSR 659 or Winter v ASC (1995) 56 FCR 107.
45 In Laycock v Forbes, Goldberg J expressly referred to the need to disclose the material upon which the decision-maker proposed to rely "so that the relevant person can respond to it" (25 ACSR at 667). If there were any doubt about what his Honour intended, that doubt is dispelled by his Honour's reference to Mahon v Air New Zealand Ltd [1984] AC 808 at 821 where their Lordships affirmed that a person represented at the inquiry in question and who might be affected adversely by a finding "should not be left in the dark as to the risk of the finding being made and thus deprived of any opportunity to produce additional material of probative value which, had it been placed before the decision-maker, might have deterred him from making the finding …". The same point was made in Winter v ASC (1995) 56 FCR 107 at 114.
46 A principal purpose of the hearing required by s 837(2) of the Corporations Law is to afford the person against whom a banning order is proposed an opportunity to advance argument and give evidence in answer to the material thought by the decision-maker to be adverse and properly to be taken into account in reaching the ultimate decision: cf Boucher v ASC (1996) 71 FCR 122 at 131 and Laycock v Forbes (1997) 25 ACSR 659 at 665. Indeed, the Corporations Law requires that a person not only be afforded an opportunity to be heard but also an opportunity to make submissions and give evidence "in relation to the matter", being the matter the subject of inquiry: Corporations Law s 837(2). If the procedure set down by s 837(2) of the Corporations Law and s 59(2) of the ASIC Law is designed (as I think it is) to meet the principal requirement of the rules of natural justice, then "it must be clear that the statutory procedure is insufficient to achieve justice and that to require additional steps would not frustrate the apparent purpose of the legislation" before it is appropriate for the Court to find that natural justice calls for more: Wiseman v Borneman [1971] AC 297 at 308; and Kioa v West (1985) 159 CLR 550 at 614-5 per Brennan J.
47 The appellants have submitted that they will be subject to impermissible prejudice if they are not permitted access to all the documents in the ASIC's possession which may bear upon the subject-matter of the hearing. The strength of that submission depends upon the following three propositions. First, the criterion for a banning order is whether the ASIC has reason to hold the belief described in s 829(f). Secondly, whether or not the ASIC has such a belief depends on all the relevant material in the possession of the ASIC; and thirdly, in order to meet the case against him, each appellant requires access to all such material. The argument runs in the following way in relation to Hamish McLachlan. (As I have said, Malcolm McLachlan adopted Hamish McLachlan's submissions but did not, I think, provide similar detail.) The conduct of the McLachlans which is the subject of the inquiry relates to "trading in shares and options on the accounts of the clients of … Laming" and, so counsel for Hamish McLachlan says, the allegations in relation to McLachlan junior raise issues concerning Laming's instructions and authority and the consent and investment objectives of RetireInvest clients. Those matters have already been, so counsel says, the subject of investigation by the ASIC and that being so, natural justice requires, so counsel submits, the disclosure of that information. In my view, the submission misconceives the operation of the relevant statutory provisions and what is required by the rules of natural justice in the circumstances of these cases.
48 Plainly enough, Mr Malinaric as delegate of the ASIC is required to be satisfied, after considering any submissions and evidence placed before him by the appellants, that he has reason to hold the belief described in s 829(f) of the Corporations Law before any occasion to exercise the power conferred by s 830 can arise. As I have already noted, however, it is for the ASIC to determine the nature of the circumstances which, in its view, will afford "reason for that belief", subject to any limitations expressly or impliedly arising from statute and the usual principles of judicial review: cf Minister for Aboriginal v Peko-Wallsend Limited (1986) 162 CLR 24 at 41. Further, it is for the ASIC to determine the material on which it proposes to rely to support the existence of those circumstances in the particular case. Having done this, the ASIC is required by s 837(2) of the Corporations Law to afford to the applicant, licensee or person opportunities to appear at a hearing, to make submissions and to give evidence "in relation to the matter" (including the material which, prior to the hearing, ASIC regards as adverse). If the matters or the material change prior to the ultimate decision, the rules of natural justice require the person to be informed and to be afforded an opportunity to respond. If it is for the ASIC to identify the matters and the material on which it relies as giving it the "reason to believe" referred to in s 829 of the Corporations Law, then the only matters and material which the rules of natural justice require to be disclosed to the appellants are those matters and material upon which the ASIC relies as being relevant, credible and significant to the ultimate decision. The interests of fairness do not require other material in the ASIC's possession and touching the subject-matter of the hearing to be disclosed, because it is not relied upon as adverse to the appellants' interests.
49 Moreover, absent any allegation of bad faith (and none is made by the appellants), it may be inferred that the material presently before Mr Malinaric is all the material which the ASIC regards at this stage of the process as being relevant, credible and significant to the ultimate decision. In this circumstance, I can discern no impermissible prejudice to the appellants flowing from the fact that they are to be denied access to material in the ASIC's possession touching the subject-matter of the hearing which is not relied upon by it. Cf Aboriginal Legal Service Ltd v Australian Securities Commission (1996) 22 ACSR 357.
50 Counsel for the appellants submitted that if the propositions advanced were not accepted, then the ASIC would be permitted to "quarantine" information in its possession. The appellants would be denied a chance to identify other relevant and even exculpatory material in the possession of the ASIC. This would, so counsel submitted, constitute a breach of the duty to act fairly "in that the ASIC as prosecutor has selected what material should be put to the delegate and has failed to make available to [the McLachlans] relevant material which is in its possession". Absent any allegation of bad faith on the ASIC's part, I do not think that it offends the rules of natural justice to place information upon which the ASIC does not rely and which it does not regard as relevant, credible and significant "in quarantine". Indeed, the procedure adopted in these cases conforms with those rules: the process adopted by the ASIC is designed to ensure that the material relied on by Mr Malinaric in making the ultimate decision is limited to that which has been brought to the relevant appellant's attention and in respect of which he has had an opportunity to respond. That end would, of course, have been defeated had Mr Malinaric participated in the earlier investigatory process.
51 I agree with Finn J that:
"The fact that Mr Malinaric is acting as delegate in a number of apparently related matters may, potentially at least, put him in a position where a duty to disclose such as Brennan J referred to in Kioa v West … may arise. But whether it does is a matter of fact in the particular circumstances given the information acquired in one capacity and the actual decision to be taken in another. It does not arise simply from what I call for convenience, the dual or multiple roles discharged."
