Reasoning
43 In relation to the appellant's claim that he was stopped in his interview, we accept the submission made for the respondent that it would not be open to this Court to make a finding, based on having heard the relevant portion of the tape, that the appellant was prevented from making further claims in relation to what had happened to him in Iran and his reasons for leaving Iran. Additionally, there are the other matters considered by the primary judge in his reasons on this issue to support the conclusion which he reached.
44 On the question whether the failure of the Tribunal to refer to the beating by the Ettela'at guard amounts to jurisdictional error, it is, of course, the case that a tribunal is not under obligation to address every piece of evidence: Minister for Immigration and Multicultural Affairs v Yusuf (2001) 206 CLR 323 per McHugh, Gummow and Hayne JJ at [67]-[68], although failure to make a finding on a material question of fact may reveal an error of law by the Tribunal or the failure to take into account a relevant consideration providing ground for judicial review: Yusuf per Gleeson CJ at [4]; McHugh, Gummow and Hayne JJ at [78]. The Ettela'at incident was a major claim and involved allegations of maltreatment. However, the Tribunal did not accept the truth of the additional claims which were made in the protection visa application but not in the original interview. We consider the relevant finding of fact in this issue was encompassed in the view which the Tribunal took in disbelieving claims which were not made in the original interview.
45 The third point of contention raised before the primary judge concerned the Handbook and we agree with the views of his Honour in relation to that contention.
46 There remains the appellant's contention in relation to the corroborative witness. The witness's evidence was directed to whether the appellant was, as he claimed, a political writer. The Tribunal accepted that if the appellant were a political writer for a newspaper, he would have fears of returning to Iran. It follows that the claims of the appellant would have to have been upheld by the Tribunal if it had believed the corroborative witness.
47 The basis of the Tribunal's conclusion that the corroborative witness was not a witness of truth was that he did not provide his evidence to either the Department or the Tribunal until the day of the hearing and that, in response to the Tribunal's question why he had not done so earlier, he had stated he had not seen the witness earlier and was not aware of "the legal process". Later, the Tribunal rejected the witness's explanation that he did not know "legal procedures" because he was a detainee who had negotiated "the legal processes". The nature of these processes or procedures was not identified in the reasons of the Tribunal.
48 The Tribunal wrote to the appellant on 17 April 2001 advising him of his entitlement to obtain oral evidence from another person or persons and setting the date for the hearing as 24 May 2001. The appellant's "response to hearing invitation" of 19 April 2001 nominated and named the proposed witness and stated that the evidence to be given by the witness was "to prove my claims". That was in the context of the note on the response form inviting "brief details of what evidence you expect each witness to give at the hearing". The response given was indicative that the witness was a corroborative witness. There is no evidence of any lack of compliance by the appellant of legal process or procedure in these steps.
49 The Tribunal stated that "the [appellant] made no mention of this witness in his written application of 27 February 2001". However, there was no evidence that at that time the appellant could have known of the existence of the witness. It was only when the appellant was transferred to open camp following his interview with the case officer that the opportunity to meet the witness arose. The respondent accepted that was the correct position. The appellant's advisor asserted the same position to the Tribunal but it was not dealt with by the Tribunal.
50 On 12 March 2001 the corroborative witness was himself granted a protection visa. The interview with the appellant occurred on 2 March 2001 (the date when he received the tape recording of that interview) so that he would have been released into open camp on 2 or 3 March 2001 (that being accepted for the respondent). On the basis that the corroborative witness would have left the detention centre on or shortly after 12 March 2001, there would have been a period of only approximately ten days in which the appellant could have met the corroborative witness and ascertained the relevance of his evidence.
51 In rejecting the explanation of the witness that he did not know legal procedures and so did not provide his information earlier, the Tribunal had no foundation upon which to base a conclusion that the witness should not be believed on that ground. Counsel for the respondent was unable to inform the Court of any "legal procedures" or any provisions under the Act directing or facilitating a witness, whom an applicant required the Tribunal to hear, to "provide information". The evidence, previously referred to, was that the appellant had done all required of him by the forms issued by the Department to identify his witness and briefly state the evidence of that witness. Likewise there was no foundation for the Tribunal's reasoning in relation to the nature of the corroborative evidence being known at the time of the application, the meeting of the appellant and the corroborative witness not then having taken place. There was, therefore, no foundation upon which the Tribunal could have reached its crucial finding of disbelief in the corroborative witness.
52 For the respondent it was conceded that the Tribunal may have made an error in its assessment of the position of the witness. However, it was submitted that did not mean there was not material before the Tribunal upon which it could have concluded it did not believe the witness's evidence. In support, reference was made to the opportunity for the appellant to have raised the matter prior to the delegate's decision on 21 March 2001. Additionally, there was the fact that the appellant had not raised the claim of his involvement in political writing in his initial interview.
53 For the respondent it is contended that the claim by the appellant to be a political writer was not an independent claim. Rather it was to be viewed in respect of all of the other facts and the matrix of material which was before the Tribunal, including the very crucial fact that the appellant did not initially make any claims in relation to writing newspaper articles or fear persecution because of writing them. For the appellant it may be said, however, that if the single fact of the appellant's involvement in political writing had been established by the evidence of the corroborative witness, the findings of the Tribunal on other matters would have become irrelevant. The Tribunal's acceptance that the establishment of the fact of political writing by the appellant would lead to a finding of well-founded fear of persecution for a Convention reason shows that the Tribunal itself approached the matter on that basis.
54 The unwarranted assumptions of the Tribunal as to matters relevant to formation of a view on the credibility of the corroborative witness caused the Tribunal to disbelieve and disregard that evidence and constituted a failure by the Tribunal to duly consider the question raised by the material put before it: Re Refugee Review Tribunal; Ex parte Aala (2000) 204 CLR 82 per Gleeson CJ at [4]. Although the remarks of the Chief Justice in Aala were directed to entitlement to review by constitutional writ on the ground of absence of authority for the Tribunal to make a decision that exercised the decision-making power in a manner that was not procedurally fair, his Honour's comments are equally pertinent to an unauthorised exercise of decision-making power that results from the Tribunal failing to take into account relevant material. In misunderstanding the material before it, the Tribunal thereby failed to have regard to relevant material, resulting in a decision for which the Tribunal had neither authority nor jurisdiction under the Act: Yusuf per McHugh, Gummow and Hayne JJ at [82]-[85]. It follows that grounds for review of the Tribunal's decision arise under s 476(1)(b) and (c) of the Act.
