See para [26] above.
29 There are sub-purposes contained within the purpose set out in s 86(1). These sub-purposes are:
• ascertaining observance of awards;
• ascertaining observance of certified agreements;
• ascertaining observance of the requirements of the Act, other than those imposed by s541.
30 When an inspector seeks the production of documents under s 86, she or he will have a sub-purpose in mind. The inspector may wish to ascertain observance of an award or observance of a certified agreement or observance of a provision of the Act. Ordinarily therefore it will not be an onerous requirement for the inspector to say in the notice for production that the documents are sought for the particular sub-purpose that the inspector has in mind. It may be one or more of the sub-purposes in s 86(1) set out in the preceding paragraph. A mere statement of the general purpose for which the inspector's powers are conferred will not inform the recipient about the relevance or legitimacy of the request contained in a notice. The power confirmed by s 86(1)(c) is referable to a purpose. The inspector must have a purpose in seeking production of the document. That purpose will relate to observance of the Act, an award or an agreement. It will trouble the inspector little to identify that purpose and once identified, allow the recipient of the notice to adjudge its relevance and hence the validity of the request.
31 A failure to identify the award, certified agreement or the requirement of the Act pertinent to the inspector's investigation will not demonstrate a relevant purpose for the recipient of the document. The inspector has sworn an affidavit in which she states that her purpose in giving the notice relates to an investigation concerning alleged breaches of s 187AA. There is no reason why the inspector could not have disclosed that purpose in her notice. Instead she chose to keep the recipient guessing as to what particular purpose she may have had in mind.
32 A notice under s 86(1A)(c) has a coercive and invasive character. The privilege against self-incrimination is abrogated by s 86(4B). Under s 305(1) it is an offence, punishable by up to six months imprisonment to contravene a requirement made by an inspector under s 86(1A)(c). Consequently there must be strict compliance with the requirements of s 86, if a notice is to be valid. To be valid, it must be obviously so, on its face, or be demonstrably relevant, without reference to extrinsic material, to a purpose referred to in s 86(1).
33 There are no reported authorities, of which I am aware, that deal with s 86, save for Heerey J's most persuasive analysis in his interlocutory judgment in this proceeding: Thorson v Pine [2004] FCA 805.
34 Counsel for the applicants drew the Court's attention to cases dealing with notices given pursuant to s 155 of the Trade Practices Act 1974 ("the TPA"). Counsel for the inspector sought to downplay the significance of such cases by reference to the different phraseology used in the TPA when compared to the Act. Counsel drew attention to the opening words of s 155(1) which refer to where there is "reason to believe that a person is capable of producing documents...relating to a matter that constitutes...a contravention of this Act...". They contended that it was a precondition to the exercise of s 155 that there was a reason to believe that a purpose was capable of producing the documents sought, whereas, it was submitted, there is no precondition to the exercise of power under s 86. However, as counsel for the applicants demonstrated, there is also a precondition to the exercise of the power contained in s 86. The precondition is that the purpose identified in the notice is one which is referable to s 86(1). I therefore reject the submission put on behalf of the inspector that cases such as Bannerman v Mildura Fruit Juices Pty Ltd (1984) 2 FCR 581 are not relevant to the issue before the Court.
35 At 584 in Bannerman, Bowen CJ and Neeves J said:
"The requirement that a notice under s 155(1) identify the matter that constitutes or may constitute a contravention of the Act has a two fold purpose. First it is necessary that the notice disclose on its face that it is an exercise of the power which the subsection confers. That power depends upon the existence, objectively determined, of a "matter", in the sense in which that expression has been explained in earlier decisions of the court, that constitutes, or may constitute, a contravention of the Act and a belief in the person issuing the notice that the recipient is capable of furnishing information or producing documents relating to the matter so identified. Secondly, the identification of the matter that constitutes, or may constitute, a contravention of the Act provides for the recipient the point of reference by which to judge whether the notice validly requires the specified information to be furnished or the specified documents to be produced. It will only validly do so if the information and the documents specified in the notice can be seen, from the face of the notice itself, to be information or documents that relate to a matter of the kind described in the subsection and identified in the notice."
