'Subject to subsection (2), if an application is properly made under s 347 for review of an MRT-reviewable decision, the Tribunal must review the decision.'
It is not suggested that s 348(2) is relevant to the present matter.
26 The expression 'an MRT-reviewable decision' is defined in s 337 to have the meaning given in Div 2 of Pt 5 of the Act. Division 2 principally contains s 338. It relevantly provides:
'(1) A decision is an MRT-reviewable decision if this section so provides, unless:
(a) the Minister has issued a conclusive certificate under section 339 in relation to the decision; or
(b) the decision is an RRT-reviewable decision; or
(c) the decision is to refuse to grant, or to cancel, a temporary safe haven visa.
…
(3) A decision to cancel a visa held by a non-citizen who is in the migration zone at the time of the cancellation is a MRT-reviewable decision unless the decision:
(a) is covered by subsection (4); or
(b) is made at a time when the non-citizen was in immigration clearance; or
(c) was made under subsection 134(1), (3A) or (4) or section 501.'
It is not suggested that any of the provisos in ss 338(1) or (3) are relevant to the present circumstances.
27 In our view, the clear words of s 338 indicate that the decision of the delegate of the respondent to cancel the visa was an 'MRT-reviewable decision' and the Tribunal was not only entitled to, but obliged to, review it.
28 The expression 'decision' is not otherwise defined in the Act. There is no textual suggestion that the expression 'MRT-reviewable decision' should be restricted in some way so as to refer only to decisions which have been made by a delegate of the respondent after full compliance with the mandatory procedural prescriptions of ss 119 - 121 (in the case of the cancellation of a visa) or other procedural prescriptions applicable to other forms of MRT- reviewable decisions. There is no qualification upon the use of the word 'decision' requiring it to be a 'decision under the Act': cf Plaintiff S157/2002 v Commonwealth of Australia (2003) 211 CLR 476; [2003] HCA 2. In particular, there is nothing in Pt 5 of the Act which would suggest that the Tribunal does not have the power or obligation to review a decision properly brought before it (see s 347) where the delegate of the respondent may, or may arguably, have failed to comply with a procedural requirement imposed by the Act, or in some other way may, or may arguably, have committed an error of law either in determining the applicable law or in applying the law. There is no reason why the Act, which provides for a full merits review by the Tribunal of decisions which may be brought to it, should impose upon the Tribunal the task of culling out those decisions which may involve jurisdictional error on the part of the original decision-maker. That would impose an unnecessary additional complexity upon the merits review process. Moreover, it may expose the Tribunal's decision as to the existence of a valid delegate's decision (a jurisdictional fact on the appellant's argument) to review by a Court even where (as here) the Tribunal has fully reviewed the decision on the merits. Administrative convenience strongly points to an alternative conclusion to that urged by senior counsel for the appellant. The review process applicable to the Tribunal is a full merits review. As with review under the Administrative Appeals Tribunal Act 1975 (Cth) (the AAT Act), the Tribunal is given powers under s 349 to exercise all the powers and discretions that are conferred by the Act on the person who made the decision. It may affirm the decision, vary it, or remit the matter for reconsideration with directions or recommendations, or may set aside the decision and substitute a new decision. The only limit upon its power is that it may not, by varying or setting aside a decision and substituting a new decision, make a decision that is not authorised by the Act or the regulations (s 349(4)). That is similar to the review powers of the Administrative Appeals Tribunal (AAT): see AAT Act, s 43. In that context it has been held that the review by the AAT is available even though the decision-maker at first instance may have made a decision which is legally ineffective: see e.g. Clements v Independent Indigenous Advisory Committee [2003] FCAFC 143 at [38] - [39].
29 That approach accords with a line of decisions of this Court beginning with Collector of Customs (NSW) v Brian Lawlor Automotive Pty Ltd (1979) 24 ALR 307 (Lawlor). In that case the Court had to decide whether the AAT had jurisdiction to review the purported revocation of a licence where (the Court held) there was no statutory power to revoke the licence. Bowen CJ at 314 stated that 'decision' in s 25 of the AAT Act refers to 'a decision in fact made, regardless of whether or not it is a legally effective decision'. Smithers J at 337 held that where a decision is made beyond power, even though the legal effect the decision maker sought to achieve is denied, the jurisdiction of a court or appeal tribunal to review the decision is not removed. The jurisdiction of the court or tribunal depends upon the law creating the right to review and conferring jurisdiction. His Honour further pointed out that a 'decision', as used in the relevant statute, relating to the right to apply for review, referred to a decision 'made in fact' and not the legal effect the decision may have had. Although Deane J was in dissent in the result, his Honour recognised at 342 - 343 that the AAT's powers of review would include a decision resulting from a wrong assessment of the content of a power or a mistaken determination that conditions precedent have or have not been fulfilled.
30 Lawlor was applied by the Full Court in Secretary, Department of Social Security v Alvaro (1994) 50 FCR 213 (Alvaro). Von Doussa J (with whom Spender and French JJ agreed) held at 219 that the right of the AAT to review a decision of the Social Security Appeals Tribunal (SSAT) existed 'whether or not the decision reviewed by the SSAT, or the decision of the SSAT itself, was legally effective'.
31 In Yilmaz v Minister for Immigration and Multicultural Affairs (2000) 100 FCR 495; [2000] FCA 906 (Yilmaz) Gyles J (with whom Spender J agreed, Marshall J dissenting) followed the principles as established in Lawlor in holding that an invalid decision (in that case concerning rights of review by the Refugee Review Tribunal (RRT) under ss 411 and 412 of the Act) is a decision capable of being reviewed by the RRT. His Honour, after discussing the relevant authorities including Lawlor and Alvaro stated at 514, [88]:
'In my opinion, these principles are to be applied in the present setting. Brian Lawlor was a landmark decision in the early days of the jurisdiction of the AAT which had been established to conduct review of certain administrative decisions on the merits as part of a comprehensive set of administrative law reforms. The decision has stood now for over 20 years without dissent and has been regularly applied. It must be taken to have been the law when the RRT provisions were framed.'
The reasoning of Gyles J in Yilmaz was followed by the Court (Moore, Tamberlin and Goldberg JJ) in Thayananthan v Minister for Immigration and Multicultural Affairs (2001) 113 FCR 297; [2001] FCA 831.
32 It should therefore be concluded that the Tribunal did have power to review the delegate's decision. The Tribunal was, in consequence, able to "cure" the defect in the delegate's decision: see Twist v Randwick Municipal Council (1976) 136 CLR 106 at 116. Because of our conclusion it is unnecessary to enter upon the question whether a direct challenge could have been made to the delegate's decision in judicial review proceedings in disregard of the procedure for Tribunal review: cf Re Minister for Immigration & Multicultural Affairs; Ex parte Miah (2001) 206 CLR 57.
