The Statutes in Question
1. The AAT Act
The only provisions to which reference need be made are s 25 and s 43 of this Act. Section 25 provides (inter alia) that:
"25 (1) An enactment may provide that applications may be made to the Tribunal:
(a) for review of decisions made in the exercise of powers conferred by that enactment;
…
(4) The Tribunal has power to review any decision in respect of which application is made to it under any enactment."
I note in passing that it is s 64 of the SRC Act which performs the function envisaged by s 25(1)(a) of the AAT Act of specifying the type of decision - "a reviewable decision" - for which application for review may be made to the Tribunal. As will be seen only decisions under particular provisions of the SRC Act are capable of giving rise to a "reviewable decision".
For its part s 43(1) provides (inter alia):
"43 (1) For the purpose of reviewing a decision, the Tribunal may exercise all the powers and discretions that are conferred by any relevant enactment on the person who made the decision …." (Emphasis added)
The purposive limitation on the power so given the Tribunal by this provision is of no little importance in this proceeding.
2. The SRC Act
It is necessary to detail some number of the provisions of this Act.
The centrepiece of the SRC is s 14(1) which, subject to the Part in which it appears, makes Comcare liable to pay compensation "in accordance with this Act" in respect of an "injury" (defined in s 4) suffered by an employee that results variously in death, incapacity for work, or impairment. The Act in individual sections goes on to particularise types of compensation that are payable under the Act, ie compensation (a) for loss of, or damage to, property (s 15); (b) in respect of medical and related expenses (s 16); (c) for injuries resulting in death (s 17); (d) for funeral expenses (s 18); (e) for injuries resulting in incapacity (ss 19-22); (f) for injuries resulting in permanent impairment (ss 24 and 27); and (g) compensation for household services etc (s 29).
Of these various provisions I would note the following. First, the decision to refuse the taxi fares was made under s 16 and the proposed decision on permanent impairment would be made under s 24. Secondly, decisions made under each of the statutory provisions referred to above are capable of giving rise to "reviewable decisions" for the purpose of an application to the Tribunal by virtue of s 64 of the SRC Act.
Part V of the SRC Act regulates the making of "claims for compensation". While that Part clearly contemplates that a claim may be made under a particular section (see eg s 54(2)(b); s 54(3); s 55(4); s 56) for a particular type of compensation, it does not in terms require that a separate application be made in respect of each different type of compensation payment to which a particular claimant may be entitled.
When a claim is made Comcare (see s 4 "relevant authority") may require an employee to undergo medical examination; and it may request the provision of information and the production of documents.
A distinctive (though by no means unique) feature of the SRC Act is its particularised review procedure. And it is this procedure that provides the pathway to applications to the Tribunal. For present purposes, the Act envisages a three-tiered process of decision making:
(i) an initial "determination", a term defined in s 60(1) of the SRC Act as follows:
"determination" means a determination, decision or requirement made under section 8, 14, 15, 16, 17, 18, 19, 20, 21, 21A, 22, 24, 25, 27, 29, 30, 31, 34, 36, 37 or 39, under paragraph 114B(5)(a) or under Division 3 of Part X;
(ii) a reconsideration of that determination by the person who made it (or a delegate) undertaken on his or her own motion or at the request of (inter alia) the claimant: s 62; the determination so reconsidered then becoming what the Act in s 60 designates to be a "reviewable decision" ie -
"a decision made under … section 62"; and
(iii) an application to the Tribunal under s 64 which provides (inter alia):
"64. (1) Application to the Administrative Appeals Tribunal for review of a reviewable decision may be made by:
(a) the claimant; … ."
The obvious, but important, point to be made of this tiered process is that application can only be made to the Tribunal to review a decision made under the Act (a) if the decision itself was made under a section that can give rise to a s 60 "determination"; and (b) that decision has been reconsidered so as to constitute a s 62 "reviewable decision".
For the sake of completeness and because of their relevance to a submission made by the second respondent I note the following SRC Act provisions.
"69. Subject to this Act, Comcare has the following functions, in addition to its other functions under this Act:
(a) to make determinations accurately and quickly in relation to claims and requests made to Comcare under this Act;
…
72. In performing the function referred to in paragraph 69(a), Comcare:
(a) shall be guided by equity, good conscience and the substantial merits of the case, without regard to technicalities;"
