It is agreed by the parties before me that a successful challenge to the Tribunal's conclusion that the December 1991 incident did not occur would lead to the conclusion that the matter would have to be remitted to the Tribunal for further consideration. It is also implicit in the submissions on behalf of the applicant that it is conceded that the only matter in contention before me concerns the December 1991 incident.
There is little doubt that the real complaint against the Tribunal's decision is that the Tribunal did not believe the applicant's narration of the events of December 1991. However, the question whether or not the Tribunal believed the applicant, or for that matter whether the applicant was then detained, is a matter for the Tribunal and not for the Court. There is a clear distinction which must, at all times, be observed between a merits review aimed at reaching the right or preferable decision on the merits and judicial review which broadly, and subject to statutory abrogation, is concerned with legal error: cf Minister for Immigration and Ethnic Affairs v Wu Shan Liang (1996) 70 ALJR 568.
THE GROUNDS OF JUDICIAL REVIEW PLEADED
The ADJR Act gave to the Federal Court of Australia exclusive jurisdiction to review decisions of an administrative kind made under Commonwealth enactments, except as otherwise by that Act excluded. It set out, largely by way of codification of the common law, the grounds upon which this Court might review Commonwealth administrative decision-making. Those grounds include a ground of review on the basis that natural justice was not afforded, a ground that there was a failure to take into account relevant matters or there was account taken of irrelevant matters, a ground that the decision was, in the administrative law sense, unreasonable, and a ground that there was no evidence or other material to justify the making of the decision: see respectively, ss5(1)(a), 5(2)(b) and 5(2)(a), 5(2)(g) and 5(1)(h).
That jurisdiction, in relation to decisions of the Tribunal, was, however, removed by s485 of the Act inserted by the Migration Reform Act 1992. The history and changes relevant to the present case are set out in the judgment of Sackville J (at 32 ff) in Minister for Immigration and Multicultural Affairs v Ozmanian (Full Court, unreported, 21 November 1996), a judgment with which Jenkinson and Kiefel JJ agreed, and see the judgment of Lehane J in Mahboob v Minister for Immigration and Ethnic Affairs (1996) 135 ALR 693 referred to and approved in the judgment of the Full Court in Ozmanian.
For relevant purposes therefore, the jurisdiction of the Court in the present reference is confined to that
conferred by the Act, the grounds for which are those contained in s476. That section provides as follows:
"(1) Subject to subsection (2), application may be made for review by the Federal Court of a judicially-reviewable decision on any one or more of the following grounds:
(a) that procedures that were required by this Act or the regulations to be observed in connection with the making of the decision were not observed;
(b) that the person who purported to make the decision did not have jurisdiction to make the decision;
(c) that the decision was not authorised by this Act or the regulations;
(d) that the decision was an improper exercise of the power conferred by this Act or the regulations;
(e) that the decision involved an error of law, being an error involving an incorrect interpretation of the applicable law or an incorrect application of the law to the facts as found by the person who made the decision, whether or not the error appears on the record of the decision;
(f) that the decision was induced or affected by fraud or by actual bias;
(g) that there was no evidence or other material to justify the making of the decision.
(2) The following are not grounds upon which an application may be made under subsection (1):
(a) that a breach of the rules of natural justice occurred in connection with the making of the decision;
(b) that the decision involved an exercise of a power that is so unreasonable that no reasonable person could have so exercised the power.
