3.1 The grounds raised in the notice of appeal
13 Neither this Court nor the Federal Circuit Court is empowered on an application for judicial review to consider the merits of the Tribunal's reasons for its decision but can adjudicate only on whether the Tribunal has made a jurisdictional error in reaching its decision, that is, whether the decision is made within lawful boundaries: see Craig v South Australia (1995) 184 CLR 163 at 179.
14 As the Minister submitted, leave is required to raise a ground of appeal which was not raised in the Court below and, where there is no adequate explanation for the failure to take the point and it seems to be of doubtful merit, leave should generally be refused: VUAX v Minister for Immigration and Multicultural and Indigenous Affairs [2004] FCAFC 158 at [48].
15 Turning then to the grounds of appeal, first, the fact that the Tribunal disbelieved the appellant's claims does not give rise to any perception of bias or demonstrate bias against the appellant. It was open to the Tribunal to disbelieve the appellant's claims on the evidence before it and the Tribunal set out in detail logical and clear reasons for reaching its decision by reference to the evidence. Furthermore, it is apparent from the detailed description of the questions asked by the Tribunal and answers given by the appellant at the Tribunal hearing that each of the matters which led the Tribunal to disbelieve the appellant's claims were put to her and she was given an opportunity to respond to them. In this regard, it is important to bear in mind that proceedings before the Tribunal are inquisitorial in nature. In that context, there was nothing necessarily inappropriate in the Tribunal testing the appellant's evidence in the course of the hearing by putting to her matters of concern and giving her an opportunity to respond. As Gleeson CJ, Gaudron and Gummow JJ stated in Re Refugee Review Tribunal; Ex parte H (2001) 75 ALJR 982; 179 ALR 425 at [30]-[31]:
Where, as in the present case, credibility is in issue, the person conducting inquisitorial proceedings will necessarily have to test the evidence presented often vigorously. Moreover, the need to ensure that the person who will be affected by the decision is accorded procedural fairness will often require that he or she be plainly confronted with matters which bear adversely on his or her credit or which bring his or her account into question. Similar questions by a judge in curial proceedings in which the parties are legally represented may more readily give rise to an apprehension of bias than in the case of inquisitorial proceedings.
Where, however, parties are not legally represented in inquisitorial proceedings, care must be taken to ensure that vigorous testing of the evidence and frank exposure of its weaknesses do not result in the person whose evidence is in question being overborne or intimidated. If that should happen, a fair-minded lay observer or a properly informed lay person might readily infer that there is no evidence that the witness can give which can change the decision-maker's view.
16 The appellant's migration agent did not attend the Tribunal hearing. The detailed record of the hearing in the Tribunal's reasons does not, in my view, suggest that this was a case in which its questioning might have given rise to the kinds of concerns to which the High Court referred to in Ex parte H. Moreover, at the conclusion of the Tribunal hearing and after the Tribunal had put to the appellant its doubts about the credibility of her claims, she was offered an adjournment in order to give her a further opportunity to comment, which she refused (at [39]). She was also asked if she had anything more she would like to say to which she responded "no". It follows that I do not consider that there is any merit in the first ground of appeal.
17 With respect to the second ground of appeal, the finding or findings of fact in respect of which it is alleged that the Tribunal failed to provide adequate reasons are not identified. Nor, on a careful reading of the Tribunal's decision, can I see any basis on which such an allegation could be upheld. On the contrary, it follows from what I have already said that I do not consider there has been any failure by the Tribunal to provide adequate reasons for its findings, even if a failure to give adequate reasons established jurisdictional error.
18 With respect to the third ground of appeal, the allegation is made that the Tribunal "made an offensive finding based on no evidence." By "offensive", I understand the appellant to contend that a finding has been made which is contrary to law because there was no evidence on which such a finding could be made. In principle, such a finding may establish jurisdictional error. However, no such finding is identified or apparent from the Tribunal's reasons, which disclose the evidence on which the Tribunal's findings were based.
19 It follows that none of the grounds of appeal alleged can be upheld and leave to plead the new grounds should be refused.
