42 Finally, counsel referred to Racecourse Co-operative Sugar Association Ltd v Attorney-General (Queensland) (1979) 142 CLR 460. The High Court held, inter alia, that in delegating to the Sugar Board the power to determine the value or price of certain acquired sugar by reference to discretionary matters, the Governor-in-Council had not 'determined and declared' the value or 'fixed' the price of the sugar as required by s 6 of the Sugar Acquisition Act 1915 (Qld). Gibbs J at 481 said:
'A power given to one person to determine a value or fix a price will not be validly exercised by allowing another to exercise a wide and unreviewable discretion in determining that price, although the person upon whom that power is conferred may, instead of fixing a money sum himself, "lay down a method of finding it which will produce the same result whoever applies it, so long as he uses it correctly" Cann's Pty Ltd v The Commonwealth [at 228]'.
43 The point which emerges from those cases relevant to determining present issue is that its resolution depends upon the proper construction of s 7C(1)(e) in its context.
44 The ACC Act is the outcome of the substantial amendments to the National Crime Authority Act 1984 (Cth) effected by the Australian Crime Commission Act 2002 (Cth). The Second Reading Speech for the Australian Crime Commission Establishment Bill 2002 (Commonwealth Parliamentary Debates House of Representatives, 26 September 2002, pp 7328- 7330) indicates that the ACC was intended by the Commonwealth, the States and the Territories to replace the National Crime Authority, the Office of Strategic Crime Assessments and the Australian Bureau of Criminal Intelligence; and the ACC was intended to result in more effective national law enforcement operations in conjunction with state and territory police forces. The ACC was intended thereby to enhance law enforcement co-ordination at a national level, by setting up a co-ordinated national criminal intelligence framework, and to improve the ability to combat serious and organised crime across jurisdictional boundaries. See S v ACC at [6].
45 It is clear that the Board is constituted to reflect and have regard to those various interests. It is to be no mere cypher. Its functions under s 7C indicate that it has overall control of the ACC in the performance of its functions. It decides on national criminal intelligence priorities and it provides strategic direction to the ACC and determines priorities for the ACC: s 7C(1)(a) and (b). Its functions under s 7C(1)(c) and (d) are referred to above. The Board may determine under s 7C(1)(d) that an authorised investigation is a special investigation only if at least nine Board members (including at least two eligible Commonwealth Board members) vote for it: s 7G(4). Correlative provisions addressing the ACC's functions in s 7A reflect that. The ACC may only conduct an intelligence operation or an investigation into federally relevant criminal activity when authorised by the Board: s 7A(b) and (c). It must provide reports to the Board on the outcomes of those operations or investigations: s 7B(d). It must provide strategic criminal intelligence assessments to the Board and its advice on national criminal intelligence priorities: s 7A(e) and (f). The Board in turn may disseminate to the appropriate agencies the strategic criminal intelligence assessments made by the ACC.
46 The Board must also report to the Inter-Governmental Committee on the ACC's performance: s 7C(l)(h). The Inter-Governmental Committee constituted under s 8 comprises the designated Ministers of the Commonwealth and of each participating State. Its functions include monitoring generally the work of the ACC and of the Board, and the oversight of their strategic direction: s 9(1)(a) and (b). It is notified promptly of a determination by the Board that an intelligence operation is a special operation or that an authorised investigation is a special investigation under s 7C(2) or (3) respectively in the performance of the Board's functions, and it may then seek further information concerning the determination, and it may revoke the determination: s 9(2) and (7). Its oversight of the Board and of the ACC is thus at Ministerial level, but it is nonetheless a significant role.
47 The overall context of the Board's role is also enlightened by the further reporting obligations of the ACC when carrying out authorised intelligence operations or authorised investigations into federally relevant criminal activity. Evidence of offences obtained by the ACC must be assembled by the CEO and given to the relevant law enforcement agency or prosecuting authority of the Commonwealth or State or Territory: s 12. The ACC is obliged to work, so far as practicable, with other law enforcement agencies: s 17. It has information gathering powers: ss 19A and 20. It has the right to apply for certain search warrants in respect of ACC special operations or investigations: s 22. That function is performed through or by an 'eligible person', defined as an examiner or a member of the staff of the ACC who is also a member of the Australian Federal Police or of the Police Force of a State. Also, in respect of special ACC operations or investigations, the ACC through an examiner may conduct an examination including the examiner summonsing a person to attend the examination for questioning: ss 24A and 28. A person so summoned must attend and answer questions and produce documents as required, although the use that can be made of such answers or documents may be confined: s 30.
48 It is an offence for the CEO, the members of the Board, the staff of the ACC and an examiner to make a record of, or to disclose, any information obtained in the performance of duties or functions under the ACC Act other than for the purposes of the ACC Act or of a relevant Act: s 51. Section 59 prescribes when, and in what circumstances, reports and information may be provided to others, relevantly for present purposes that the CEO may give to law enforcement agencies or other prescribed agencies of the Commonwealth or of a State or Territory information which is relevant to the activities of that agency: s 59(7). The CEO may do so if it appears appropriate to do so and would not be contrary to a law of the Commonwealth or of the State or Territory that would otherwise apply.
49 The ACC is defined in s 7(2) to consist of the CEO, the examiners (appointed under s 46B), and the members of the staff of the ACC. Section 4 provides that a member of the staff of the ACC includes persons engaged under the Public Service Act 1999 (Cth) and, 'a person participating in an ACC operation/investigation', and certain other persons.
50 Section 58 contemplates administrative arrangements with the States whereby members of a Police Force of a State may be made available to perform services for the ACC. Section 48 provides that such persons, together with persons from the Australian Federal Police or other Commonwealth authorities whose services are seconded to the ACC, may assist the ACC in the performance of its functions, and they thereby become members of the staff of the ACC as defined.
51 The inclusion in the definition of the term 'member of the staff of the ACC' of 'a person participating in an ACC operation/investigation' clearly may extend its staff members beyond those persons who perform services for the ACC under s 58. The definition contemplates a broad range of persons who may be members of the staff of the ACC. Those participating in an ACC operation or investigation (and thereby becoming members of its staff) may extend beyond the categories identified by ss 47, 48 or 49 of the ACC Act. It is also apparent that the members of the staff of the ACC may, from time to time, include seconded persons under administrative arrangements under s 49. In their cases, their secondment would not specifically be authorised or supervised by the Board. The ACC Act contemplates those arrangements being made at an operational level rather than at the Board level of decision-making.
52 It is in that broad context that s 7C(1)(e) is to be addressed. It requires the Board to determine, in writing, the class or classes of persons to participate in an ACC special operation/investigation. Those persons then have imposed on them the obligation of secrecy under s 51, and depending on their also being members of a police force the right to apply for search warrants under s 22. Counsel for the applicant contends that the Board, because those persons have such responsibilities and powers, must specify definitively the class or classes of persons to participate in the operation or investigation so as to ensure both the integrity of the investigation and the protection of those subjected to the processes of the ACC.
53 The reason why the Board needs to specify the class or classes of persons to participate in the examination is not entirely clear. One clear purpose is so that those who thereby become members of the staff of the ACC can be identified. Those identifiable persons then have the powers and obligations referred to under the ACC Act. Another clear purpose is so that the Board must control the persons who participate in its particular operations or investigations, so that it must address the particular class or classes or persons who appropriately are to participate in the particular operation or investigation. It is almost a corollary of the authorisation and determination functions of the Board that it should determine those who should participate in a particular operation or investigation. That is fortified by the requirements of s 7C(2), (3) and (4).
54 The reference to a class or classes of persons is, no doubt, to avoid the requirement that the Board nominate each individual person to participate in a particular operation or investigation. That would impose very onerous and impracticable burdens upon the Board, having regard to the sort of investigations or operations which it might authorise. The inevitability of different persons moving in and out of its operations and activities is manifest. The determination under s 7C(1)(e) is not intended to require the Board to take account of such changes.
