RELEVANT PRINCIPLES
16 Pursuant to s 8 of the ADJR Act, the Court has jurisdiction to hear and determine applications made under the ADJR Act. Section 5 of the ADJR Act provides that a person aggrieved by a decision to which the Act applies may apply to the Court for an order of review on certain grounds. Section 6 of the ADJR Act provides for review of conduct, engaged in, being engaged in or proposed to be engaged in for the purpose of making a decision to which the ADJR Act applies.
17 It is apparent from the definition of 'decision to which this Act applies' in s 3 of the ADJR Act that the Act only applies where there is a making of, proposal to make or requirement to make a decision, the decision is of an administrative character, and the decision is made under an enactment. In Australian Broadcasting Tribunal v Bond (1990) 170 CLR 321 (at 335), Mason CJ discussed the meaning of 'decision' under s 3 of the ADJR Act and held (relevantly) (citations omitted):
(1) Meaning of "Decision"
The definition in s.3(1) does not elucidate significantly the meaning of the word "decision" as it is used in the A.D.(J.R.) Act. It is clear that a "decision to which this Act applies" must be a decision of an administrative character, that it may be made in the exercise of a discretion, and that it must be made under an enactment. But these characteristics provide little guidance as to the meaning of the word "decision" upon which the definition in s.3(1) is based.
…
Nonetheless other considerations point to the word having a relatively limited field of operation. First, the reference in the definition in s.3(1) to "a decision of an administrative character made ... under an enactment" indicates that a reviewable decision is a decision which a statute requires or authorizes rather than merely a step taken in the course of reasoning on the way to the making of the ultimate decision. Secondly, the examples of decision listed in the extended definition contained in s.3(2) are also indicative of a decision having the character or quality of finality, an outcome reflecting something in the nature of a determination of an application, inquiry or dispute or, in the words of Deane J., "a determination effectively resolving an actual substantive issue". Thirdly, s.3(3), in extending the concept of "decision" to include "the making of a report or recommendation before a decision is made in the exercise of a power", to that extent qualifies the characteristic of finality. Such a provision would have been unnecessary had the Parliament intended that "decision" comprehend every decision, or every substantive decision, made in the course of reaching a conclusive determination. Finally, s.3(5) suggests that acts done preparatory to the making of a "decision" are not to be regarded as constituting "decisions" for, if they were, there would be little, if any, point in providing for judicial review of "conduct" as well as of a "decision".
The relevant policy considerations are competing. On the one hand, the purposes of the A.D.(J.R.) Act are to allow persons aggrieved by the administrative decision-making processes of government a convenient and effective means of redress and to enhance those processes. On the other hand, in so far as the ambit of the concept of "decision" is extended, there is a greater risk that the efficient administration of government will be impaired. Although Bowen C.J. and Lockhart J. appeared to emphasize the first of these considerations in Australian National University v. Burns, there comes a point when the second must prevail, as their Honours implicitly acknowledged. To interpret "decision" in a way that would involve a departure from the quality of finality would lead to a fragmentation of the processes of administrative decision-making and set at risk the efficiency of the administrative process.
…
Another essential quality of a reviewable decision is that it be a substantive determination. With the exception of s.3(2)(g), the instances of decision mentioned in s.3(2) are all substantive in character. Moreover, the provisions in sub-ss.(1), (2), (3) and (5) of s.3 point to a substantive determination. In this context the reference in s.3(2)(g) to "doing or refusing to do any other act or thing" (emphasis added) should be read as referring to the exercise or refusal to exercise a substantive power. I do not perceive in s.16(1)(b) or in par.(e) of Sched.1 or par.(a) of Sched.2 to the A.D.(J.R.) Act any contrary implication. These exclusions from the A.D.(J.R.) Act or from s.13 appear to have been introduced for more abundant caution and it would be unwise to take too much from them. (emphasis added)
18 Despite the clarity of the passage from the learned Chief Justice, application of the principles has not been without difficulty. Views on whether or not particular decisions or conduct constitutes a reviewable decision have not always been unanimous (for example, Guss 152 FCR 88).
19 Not only are there questions as to whether conduct constitutes a decision but also whether it is a decision taken under an enactment. For a decision to be reviewable it must be one 'for which provision is made by or under a statute', the provision should be more specific than general (for example, Hutchins v Commissioner of Taxationn (1996) 65 FCR 269 and Electricity Supply Assn of Australia Ltd v Australian Competition & Consumer Commission (2001) 113 FCR 230). A general authorisation for a body to act in a certain way is not usually regarded as being sufficient to qualify a decision as being one made under an enactment: Salerno v National Crime Authority (1997) 75 FCR 133.
20 Dealing with the enactment aspect, the majority of the High Court in Griffith University v Tang (2005) 221 CLR 99 held (at [89]) that:
The determination of whether a decision is "made … under an enactment" involves two criteria: first, the decision must be expressly or impliedly required or authorised by the enactment; and, secondly, the decision must itself confer, alter or otherwise affect legal rights or obligations, and in that sense the decision must derive from the enactment. A decision will only be "made ... under an enactment" if both these criteria are met. It should be emphasised that this construction of the statutory definition does not require the relevant decision to affect or alter existing rights or obligations, and it will be sufficient that the enactment requires or authorises decisions from which new rights or obligations arise. Similarly, it is not necessary that the relevantly affected legal rights owe their existence to the enactment in question. Affection of rights or obligations derived from the general law or statute will suffice.
21 Indeed the High Court went on to observe that even though a decision taken may have a critical effect for the operation of the federal statute, if it is a decision made 'dehors' the federal statute, it would be un-reviewable.
