Consideration
31 In our opinion, the primary judge correctly rejected the appellant's construction of s 17(1)(c)(i) of the Act and its relationship to s 17(2), which underpinned the appellant's contention that the need to write a new computer program was not a fact capable of meaning that a computer was not "ordinarily available" to the agency.
32 Fundamental to the appellant's argument were two distinct but related assertions, neither of which was, on analysis, persuasive.
33 First, the appellant contended that the computer ordinarily available to an agency for collating and retrieving stored information ("the specified purpose") in s 17(1)(c)(i) of the Act was merely computer hardware. Therefore, an agency's obligation under s 17(1) to comply with a request for access to information could never be excluded merely because it needed to obtain a new computer program in order to do so.
34 Secondly, the appellant contended that s 17(2) supported the above construction, as it satisfactorily obviated any undue burden entailed by the existence of an obligation under s 17(1) where its fulfilment required components not "ordinarily available" (including, for example, a new computer program).
35 The principles applicable to statutory construction were uncontroversial. They were recently stated by the plurality (Hayne, Heydon, Crennan and Kiefel JJ) in Alcan (NT) Alumina Pty Ltd v Commissioner of Territory Revenue (2009) 239 CLR 27; (2009) 260 ALR 1 at [47] as follows:
This Court has stated on many occasions that the task of statutory construction must begin with a consideration of the text itself. Historical considerations and extrinsic materials cannot be relied on to displace the clear meaning of the text. The language which has actually been employed in the text of legislation is the surest guide to legislative intention. The meaning of the text may require consideration of the context, which includes the general purpose and policy of a provision, in particular the mischief it is seeking to remedy. [citations omitted]
36 In our opinion, the appellant's construction conflates the distinct functions of ss 17(1) and 17(2).
37 Section 17(1) of the Act specifies particular conditions in which an agency's obligation to provide access to requested information will arise although it would not otherwise be imposed under the Act. Section 17(2) specifies the circumstances in which the agency will be exempt from compliance with the obligation under s 17(1).
38 The language and structure of s 17 and its operation within the Act as a whole make clear that the preconditions of the existence of the agency's obligation are independent of, and distinct from, the circumstances exempting the agency from compliance.
39 There is considerable potential overlap between factual matters relevant to the questions under s 17(1)(c)(i) (whether the use of a computer or other equipment is ordinarily available) and s 17(2) of the Act (whether compliance with the obligation to produce the requested document would be a substantial and unreasonable diversion of the agency's resources). The two inquiries nevertheless arise sequentially. The satisfaction of the conditions under s 17(1) is a pre-condition for the application of s 17(2). Nor, despite the overlap, are the questions interchangeable. The satisfaction of the conditions of s 17(1)(c)(i) does not ensure satisfaction of the conditions of s 17(2), and vice versa.
40 A computer or other equipment would not be ordinarily available to an agency for the specified purpose simply because it could be obtained or accessed without an unreasonable diversion of resources. Conversely, although a requested document could be produced by the use of the ordinarily available computer or other equipment, the production might nevertheless involve a substantial and unreasonable diversion of the agency's resources, which would exempt it from compliance.
41 Further, if the "computer" in s 17(1)(c)(i) be read as computer hardware only, the requirement that it be "ordinarily available" would not operate effectively to limit the existence of the obligation.
42 Rather, the requirement that the computer or other equipment capable of producing the document be ordinarily available would be largely subsumed in an inquiry whether the agency could access a computer or other equipment capable of producing the document without a substantial or unreasonable diversion of its resources.
43 In our opinion, the computer referred to in s 17(1)(c)(i) is not merely computer hardware. Rather, it means a functioning computer system including software, that can produce the requested document without the aid of additional components which are not themselves ordinarily available.
44 Section 17(1)(c)(i) is directed at ensuring that an agency will not be obliged to produce a document unless the effective and comprehensive means of doing so are ordinarily available to it for the specified purpose. In that context, the computer or other equipment ordinarily available for the specified purpose must be capable of functioning independently to collate or retrieve stored information and to produce the requested document.
45 Were it otherwise, the obligation under s 17(1) would arise whenever the agency had ordinarily available for the specified purpose computer hardware or other equipment capable of some use in the process of producing the requested document, even if the achievement of that outcome depended principally on other components that were not ordinarily available to the agency for the specified purpose or indeed, were not obtainable at all.
46 On that construction, s 17(1)(c)(i) would have no substantial or sensible operation. While the appellant submitted that it would exclude the obligation if the production of the document would require computer hardware that the agency did not ordinarily possess or access (even if it were available for purchase or acquisition in the market place), such a limitation would have a minimal and potentially anomalous application.
47 The agency would not be obliged to produce the document under s 17(1) if the necessary computer hardware was not ordinarily available even if it could be acquired without a substantial or unreasonable diversion of its resources. It would nevertheless be obliged (subject only to the possibility of exemption under s 17(2)) to do so if the computer hardware were ordinarily available even if it also required components of every other kind, irrespective of how extraordinary they were to the agency's usual operations.
48 It may be unnecessary for the purposes of this appeal definitively to determine the scope of "ordinarily available" in s 17(1)(c)(i). In our view, however, while an "ordinarily available" computer or "other equipment" is not limited to that currently in the agency's possession, it does not include that which is or may become available to the agency for the specified purpose only outside the ordinary course of its operations. Whether an item is ordinarily available will depend upon the facts of the particular case, which may include whether access to it would involve a departure from the agency's ordinary or usual conduct and operations.
49 In our view, a computer might in some cases be ordinarily available within the meaning of s 17(1)(c)(i) even if a new computer program were required in order for the computer to produce the requested document. The agency might, for example, routinely commission or retain staff to produce new computer programs of the necessary kind.
50 The Senate Committee Report appears to recognise that the need for a new computer program would usually, rather than absolutely, preclude the obligation. However, as the primary judge observed, due to its generalised tenor, the Senate Committee Report does not greatly assist in the construction of s 17(1)(c)(i).
51 While it may seem anomalous that s 17(1)(c)(i) could exclude an obligation from which (had it existed) the agency would not have secured exemption under s 17(2), the appellant's construction produces more fundamental and extensive anomalies, as it deprives s 17(1)(c)(i) of effective operation and attributes an unduly broad function to s 17(2).
52 It follows that in our opinion, the need for a new computer program to enable the computer ordinarily available to the agency for retrieving or collating stored material to produce the requested document is a fact capable of meaning that the agency cannot, by the use of a computer ordinarily available, produce the requested document.
53 As the appellant submitted, s (17)(1)(c) is not directed at the ordinary manner of use of a computer. Rather, it asks, among other things, whether a computer or other equipment (whatever the usual way of using it) is ordinarily available to the agency for retrieving or collating stored information. While the primary judge's reference to "using a computer in a manner that is ordinarily available to it" does not strictly reflect the language of the provision, his Honour recognised, correctly in our view, that the appellant's construction deprived s 17(1)(c)(i) of effective operation, that the computer "ordinarily available" to the respondent was its functional computer system comprising hardware and software; and that in that particular case, as new software was necessary to produce the requested document, the respondent could not do so by the use of its computer ordinarily available for the specified purpose, so the obligation under s 17(1) did not arise.
