Was the Tribunal's refusal to call any of the seven persons unreasonable?
64 It is, however, clear that the Tribunal nevertheless had regard to the request that the appellant made, through his lawyer, at the hearing, that the Tribunal telephone some of those witnesses. It is unclear whether, in doing so, the Tribunal considered that request in terms of the exercise of its discretion under s 426(3) of the Act. Whether it did so or not, the question arises whether the Tribunal's refusal to accede to that request was legally unreasonable in the circumstances.
65 It is abundantly clear from the statutory scheme and the inquisitorial nature of the Tribunal's review jurisdiction that a review applicant has no right to call, or require the Tribunal to call, a witness to give evidence. Moreover, as adverted to earlier, it is plain from the terms of s 426(3) of the Act that, if an applicant does notify the Tribunal - in accordance with s 426(2) of the Act - that it wants the Tribunal to obtain oral evidence from a witness, the Tribunal must have regard to the applicant's "wishes", but is not required to act on those wishes: VJAF v Minister for Immigration and Multicultural and Indigenous Affairs [2005] FCAFC 178 at [23].
66 The Tribunal's consideration of the applicant's wishes must be real and genuine, not just an empty gesture: Minister for Immigration and Multicultural and Indigenous Affairs v Maltsin (2005) 88 ALD 304; [2005] FCAFC 118 at [38]; AYX17 at [48]. The Tribunal must also not, in determining whether or not to obtain oral evidence from a witness in accordance with the applicant's wishes, act arbitrarily or capriciously and must take into account matters such as the potential relevance or importance of the proposed evidence and the sufficiency of any written evidence that may have been provided by the prospective witness: Maltsin at [38]. Like other statutory discretions, the discretion in s 426(3) must be exercised reasonably: VJAF at [22]-[23]; CZBH v Minister for Immigration and Border Protection [2014] FCA 1023 at [73]-[80]; SZUIJ v Minister for Immigration and Border Protection [2016] FCA 1574 at [53]; AYX17 at [75].
67 There could be no doubt that the Tribunal had regard to the appellant's wishes, as expressed by his lawyer at the Tribunal hearing, that the Tribunal take oral evidence over the telephone from at least some of the seven persons referred to in the witness list. That is clear from the Tribunal's reasons. The appellant did not suggest otherwise. There could also be no doubt that the Tribunal's consideration of the appellant's wishes was real and genuine, and that its response to the appellant's request could not be said to be arbitrary or capricious.
68 It is clear from the Tribunal's reasons that the Tribunal had read and considered the statements of the seven persons and gave consideration to the evidence that they had given, or were able to give: see Reasons at [55] (including the detailed footnotes referring to the statements) and [59]. It also gave considered reasons for refusing to telephone the witnesses so they could give the evidence in their statements orally. The Tribunal accepted that if oral evidence was taken from the seven persons, they would repeat the evidence in their statements: Reasons at [59]. The Tribunal concluded, however, that there was "no purpose" in having the witnesses give that evidence orally because it would not "overcome" the adverse conclusion that the Tribunal had, by that point of the hearing, reached concerning the credibility of the appellant's claims based on his own evidence.
69 There was nothing irrational, illogical or unreasonable about the Tribunal's reasons for refusing to telephone the witnesses for the purpose of having them give their evidence orally. It may be accepted that at least some of the evidence contained in some of the statements given by the seven potential witnesses was corroborative of some aspects of the appellant's claims. It does not follow, however, that the Tribunal was obliged to call oral evidence from them. Nor does it follow that it was not open to the Tribunal to reason, in effect, that the corroborating evidence of the witnesses was not deserving of any weight, or even should be rejected, in light of the fact that the appellant's own evidence about his claims had by that point been found to be inconsistent, improbable and unsatisfactory.
70 In Re Minister for Immigration and Multicultural Affairs; Ex parte Applicant S20/2002 (2003) 77 ALJR 1165; [2003] HCA 30, it was argued that the Tribunal had erred in giving no weight to corroborating evidence because it had found that the applicant's evidence lacked credibility. Gleeson CJ (in the majority) rejected that argument, reasoning as follows (at [12]):
It is not necessarily irrational, or illogical, for a finder of fact, who is convinced that a principal witness is fabricating a story, which is considered to be inherently implausible, to reject corroborative evidence, even though there is no separate or independent ground for its rejection, apart from the reasons given for disbelieving the principal witness.
71 While the Tribunal could perhaps have expressed itself more clearly, that was the effect of its reasons for refusing to telephone any of the seven proposed witnesses so they could give oral evidence along the lines of the evidence in their statements. It is readily apparent that the Tribunal, having already heard and considered the appellant's own evidence concerning his claims, determined that there was no point in telephoning any of the seven prospective witnesses to have them repeat the evidence contained in their statements. That was because, to the extent that the evidence corroborated the appellant's evidence, it would nevertheless not overcome the Tribunal's "concerns" that the appellant was not a credible witness who had fabricated his claims. In those circumstances, it was not irrational, illogical or unreasonable for the Tribunal to, in effect, determine that the corroborating evidence, even if repeated orally on oath or affirmation by the witnesses over the telephone, was deserving of no weight, or should be rejected as being unreliable or not credible.
72 It may be accepted that, in some cases, a refusal by the Tribunal to call potentially corroborating oral evidence from a witness at the request of the applicant may suggest that the Tribunal had impermissibly prejudged the review application, or had otherwise misunderstood its review task or jurisdiction: SZVBB v Minister for Immigration and Border Protection [2015] FCA 1414 at [40]-[41]. Some caution is no doubt needed before determining that it was open to the Tribunal to conclude that the proffered corroborative evidence could not alter the view that the Tribunal had formed concerning the applicant's credibility or the reliability of his or her evidence: AYX17 at [85]-[86] citing with approval W360/01A v Minister for Immigration and Multicultural Affairs (2002) 124 FCR 449; [2002] FCAFC 211 at [3].
73 In this case, however, by the time the appellant's lawyer had raised, for the first time, the possibility of the Tribunal calling some of the seven persons referred to in the witness list, the Tribunal had already heard extensive evidence from the appellant and had questioned the appellant at considerable length. It is readily apparent from the Tribunal's reasons that, in the course of that questioning, the Tribunal had highlighted many inconsistencies, improbabilities and other unsatisfactory elements in the appellant's evidence. When consideration is given to the Tribunal's detailed and comprehensive reasons concerning its "credibility concerns", it is readily apparent that there was a proper and reasonable basis for the Tribunal to conclude, at that point, that the views it had formed concerning the appellant's credibility and reliability as a witness were not going to be altered if any of the seven persons in the witness list gave oral evidence in accordance with their statements; that the appellant's "credibility could not be repaired by corroborative oral evidence" from any of the seven persons: SZVBB at [44].
74 The reasonableness of the Tribunal's decision to refuse to telephone the proposed witnesses must also be considered in light of the fact that the appellant had given the Tribunal no prior notice that it wanted the Tribunal to take oral evidence from the witnesses and had apparently made no arrangements for them to give evidence by telephone at the hearing. There was no evidence that any of the proposed witnesses, all but one of whom resided overseas, was available to take a telephone call at the time of the hearing.
75 The appellant contended that the witness statements of the seven persons were brief and that, if the Tribunal had taken oral evidence from them over the telephone, their evidence may have been elaborated on or expanded in some relevant and material way. That submission has no merit. The appellant's lawyer did not suggest to the Tribunal that the oral evidence of the proposed witnesses would or even might add anything to what they had included in their statements. Nor is there any basis for suggesting that that might be the case. That is a matter of pure speculation.
76 There is, in any event, no proper basis for concluding that the Tribunal was obliged to call oral evidence from the witnesses so they could expand or elaborate on what they had included in their witness statements: see BTF15 v Minister for Immigration and Border Protection (2016) 69 AAR 376; [2016] FCA 647 at [55]. Nor was the Tribunal obliged to call oral evidence from the witnesses so that their accounts could be challenged or tested. Proceedings in the Tribunal are inquisitorial, not adversarial, and the rule in Browne v Dunn does not apply: Re Minister for Immigration and Multicultural Affairs; Ex parte Applicant S154/2002 (2003) 201 ALR 437; [2003] HCA 60 at [57].
77 It follows that there is no merit in the appellant's contention that the Tribunal's exercise of its discretion to not call oral evidence from the seven persons listed in the witness list was in any way legally unreasonable. The decision was within the area of decisional freedom conferred on the Tribunal in the exercise of its discretion under s 426(3) and s 427(1)(a) of the Act. There was also a rational, reasonable and intelligible justification for the decision. It was not arbitrary, capricious or unjust in all the circumstances.
78 The primary judge's reasons for rejecting the contention that the Tribunal had acted unreasonably in the exercise of its discretion not to call oral evidence from the seven persons were brief: Judgment at [42]. His Honour was nonetheless correct, and did not err, in reaching that conclusion.
79 It should finally be reiterated that the appellant expressly withdrew and abandoned any contention that the Tribunal's refusal to telephone the seven persons on the witness list breached any provision of the Act other than s 426(3), or otherwise amounted to a denial of procedural fairness. It is accordingly unnecessary to address that issue in any detail. It suffices to note that, given the finding that has been made that the Tribunal did not act unreasonably in in the exercise of its discretion under s 426(3) of the Act, it is difficult to see any possible basis upon which it could be contended that the Tribunal somehow breached any of the other sections of the Act previously relied on by the appellant.
80 It follows that the appellant's first appeal ground is unmeritorious and must be rejected.
