24 An order of the kind made in Baxter Healthcare 72 FCR 467 is said to be necessary in this case because, without it, the ACCC would be under a continuing obligation to make comprehensive determinations of model terms and conditions for each of the core services specified in s 152AQB(1). The discharge of such an obligation would impinge severely on the ACCC's resources and have serious implications for access providers and access seekers as well as being likely to affect competition in relevant markets. In addition, it was pointed out, if the construction preferred by the primary Judge were to prevail, the validity of existing determinations would be called into question including that for the model terms and conditions made by the ACCC in November 2008 ("the 2008 Determination"). That, in turn, would have ramifications for any arbitration by the ACCC which took account of existing model terms and conditions.
25 The ACCC accepts that it is bound by s 152AQB(2) to make a determination of some model terms and conditions governing access to each core service. However, it argued that the scope and content of those terms and conditions is a matter of judgment for the ACCC. The judgment must be formed bona fide for the purpose for which the power was conferred but is not constrained by a need to ensure that each set of terms and conditions is "comprehensive".
26 The construction for which the ACCC contends is said to be supported by the text, context and purpose of s 152AQB read as a whole. Counsel for both the ACCC and Optus have pointed out that the reference to "model terms and conditions" in s 152AQB(2) is not qualified by any such adjective as "all" or "all material" and is not preceded by the definite article "the". Any of those drafting techniques, or others just as readily available, could have been used had it been intended that each set of model terms and conditions should be "comprehensive".
27 At its lowest, according to the ACCC, s 152AQB(2) is ambiguous. As a result, recourse can properly be had to extrinsic material to illuminate or determine the meaning of the provision. The ambiguity, if there be one, is directly resolved, the ACCC and Optus claim, by the statement in the explanatory memorandum produced at [14] above that "the model terms and conditions will not need to be comprehensive".
28 The learned primary Judge's invocation of Re Bolton 162 CLR 514 in support of eschewing recourse to the explanatory memorandum was criticised by Counsel for the ACCC. They pointed out that s 15AB of the Acts Interpretation Act 1901 (Cth) ("the Acts Interpretation Act") expressly permitted resort to the explanatory memorandum and the High Court in Re Bolton 162 CLR 514 acknowledged that utilising the relevant second reading speech as an aid to interpretation was not only permissible but required "earnest consideration". Moreover, in Re Bolton 162 CLR 514 there was a reluctance to use the extrinsic material to extend the reach of the statute so that it rebutted the common law presumption in favour of a construction conducive to the liberty of the subject: see eg Re Bolton 162 CLR 514, at 520. By contrast his Honour declined to allow the extrinsic material to restrict what he considered to be the full reach of the statutory language.
29 The difficulties inherent in his Honour's interpretation were said to be exemplified by his references at [36] of his reasons to "leaving out of a determination … some or all material terms", and at [37] to a possible need to "not make all appropriate model terms and conditions" (emphasis added) (see [12] above). As well, at [43] of his reasons, his Honour declined to impute to the legislature an intention to leave unexpressed "important terms and conditions for the provision of access" and identified at [44] the purpose of a model as being to ensure awareness "of the usual terms and conditions applicable in the relevant situation" (emphasis again added) (see [18] and [19] above).
30 Allied to the difficulties just described was what the ACCC and Optus said is the inherently indefinite nature of formulating a set of terms and conditions to provide for every contingency which may arise out of the contractual relationship which they are intended to govern. That is particularly so, the ACCC claimed, in relation to a technically, physically and commercially complex activity such as the provision of telecommunications services. A related consideration is the absence of a reasonably certain legal standard against which a court could determine whether a set of model terms and conditions contained "all" or "all material" terms and conditions relating to access. Those expressions denote "a category of indeterminate reference". In the same context Counsel for Optus pointed to the "significant scope for disagreement among access providers, access seekers and the ACCC about what types of terms and conditions are required in order to deal 'comprehensively' with the terms and conditions of access".
31 In seeing s 152AQB(2) in context, the ACCC argued, note must be taken of the limited operation given by s 152AQB(9) set out at [22] above to a determination of model terms and conditions. The sole operative effect of that sub-section is to require the ACCC to have regard to the model terms and conditions when arbitrating a dispute about access. The primary Judge was said to be mistaken in regarding, at [39] of his reasons, s 152AQB as obliging Telstra, amongst others, to ensure that access is given in accordance with the model terms and conditions. That misconception led his Honour to characterise the section as a law "restrictive of the liberty of an individual" and as affecting "freedoms and obligations" (see [40] and [42] of the reasons at first instance).
32 In support of the construction for which it contended, the ACCC drew on the object of Part XIC of the Act which is identified in s 152AB(1) as the promotion of the long-term interests of end-users of listed services. It is then stipulated in s 152AB(2) that, in determining whether a particular thing promotes the object of Part XIC, regard must be had exclusively to the extent to which the thing is likely to result in the achievement of the following objectives:
(c) the objective of promoting competition in markets for listed services;
