CONSIDERATION
23 The basic principles as to when jurisdictional error will arise for failure to consider a relevant consideration are well-accepted. Jurisdictional error may be shown where a statutory decision-maker disregards a relevant consideration, in the sense discussed in Minister for Aboriginal Affairs v Peko-Wallsend Ltd (1986) 162 CLR 24 ('Peko-Wallsend'): see Minister for Immigration and Multicultural Affairs v Yusuf (2001) 206 CLR 323 ('Yusuf') at 351 [82], citing Craig v South Australia (1995) 184 CLR 163 at 179. That is, the ground of failure to take into account a relevant consideration is only made out if the decision-maker failed to take into account a consideration that the decision-maker was bound to take into account in making the decision: Peko-Wallsend at 39-41. Governing legislation may expressly state all these considerations, although often it does not. In this latter case, relevant considerations in this limited sense are to be determined by reference to the subject-matter, scope and purpose of the governing legislation, which, in the current context, includes the Migration Act 1958 (Cth) and the Migration Regulations 1994 (Cth): see, e.g., Yusuf at 347-8 [73] (McHugh, Gummow and Hayne JJ), citing Abebe v Commonwealth (1999) 197 CLR 510 at 579 [195]. Their Honours went on to say in Yusuf (at 348 [74]):
What is important … is that the grounds of judicial review that fasten upon the use made of relevant and irrelevant considerations are concerned essentially with whether the decision-maker has properly applied the law. They are not grounds that are centrally concerned with the process of making the particular findings of fact upon which the decision-maker acts.
24 Referring to Htun v Minister for Immigration and Multicultural Affairs (2001) 194 ALR 244 ('Htun') at 259 [42], the Minister accepted that, having regard to the statutory framework governing applications for protection visas, an applicant's claim to be a refugee and the integers of that claim are considerations that a decision-maker is bound to take into account. See also Applicant WAEE v Minister for Immigration and Multicultural and Indigenous Affairs (2003) 75 ALD 630 ('WAEE') at 641 [46]; and NABE v Minister of Immigration and Multicultural and Indigenous Affairs (No 2) (2004) 144 FCR 1 ('NABE') at 20 [63]. The Minister drew a distinction between a failure to consider an integer of a claim to be a refugee (or a contention that, if accepted, might establish a well-founded fear of persecution) and a failure to take into account evidence that, if accepted, might have led to a different finding of fact. As the Minister submitted, and I accept, a failure to refer to, or adequately to consider, evidence, whether or not it might be thought probative, does not give rise to jurisdictional error, even though it may have led to an erroneous finding of fact. The authorities for this proposition are numerous: see, for example, Minister for Immigration and Citizenship v SZNPG (2010) 115 ALD 303 at 308-9 at [21]-[28] (North and Lander JJ, with whom Katzmann J agreed (see at [35])); Htun at 259 [42] (Allsop J, with whom Spender J agreed); WAEE at 641 [46]; and Paul v Minister for Immigration and Multicultural Affairs (2001) 113 FCR 396 at 423 [79] (Allsop J, with whom Heerey J agreed). Related propositions are that the weight to be given evidence is a matter for the decision-maker and that a wrong finding of fact does not of itself give rise to jurisdictional error. Furthermore, making findings on credibility is the function of the decision-maker; and they are not ordinarily open to challenge in a court on a judicial review application: NADR v Minister for Immigration and Multicultural and Indigenous Affairs [2003] FCAFC 167 at [9]; Re Minister for Immigration and Multicultural Affairs; ex parte Durairajasingham (2000) 58 ALD 609 at 624-5 [64]-[67] (McHugh J); Abebe v Commonwealth (1999) 197 CLR 510 at 560 [137] (Gummow and Hayne JJ); and Enfield City v Development Assessment Commission (2000) 199 CLR 135 at 153-4 [44] (Gleeson CJ, Gummow, Kirby and Hayne JJ).
25 In the proceeding in the Federal Magistrates Court, the first respondent argued that the Tribunal had failed to take into account the Stewart report. The Tribunal's statement of reasons shows that this is incorrect. The Tribunal plainly had regard to the psychologists' reports, including the Stewart report: see [18] above.
26 On this appeal, the first respondent accepted the Federal Magistrate's characterization of the Stewart report as evidence "to show that his mental state was consistent with his claims of past abuse": see [20] above. In written submission, the first respondent contended that the Stewart report was presented to the Tribunal on a "quite specific basis", namely:
The [r]eport provides an assessment of the manner in which the Applicant presented in his sessions with the Psychologist - i.e. as someone who has experienced torture.
Thus, the first respondent's primary argument was that the relevance of the Stewart report was not confined to the issue of his fitness to give evidence, but corroborated his account of past persecutory events. That is, the report was, so the first respondent said, relevant to show that his psychological condition was consistent with his account of what had happened to him in Bahrain. Referring particularly to the passage from the Tribunal's reasons set out at [18] above, the first respondent contended that the Tribunal considered the Stewart report only in relation to the issue of fitness to plead and had thereby overlooked the primary purpose for which the Stewart report was presented to it. In this context, at the hearing of the appeal, counsel also drew a distinction between corroborative evidence in the nature of expert opinion and non-expert corroborative evidence.
27 Further, at the hearing of the appeal, referring to NABE at 20 [63], SZKHD v Minister for Immigration and Citizenship [2008] FCA 112 ("SZKHD"), and Illankovan v Minister for Immigration and Multicultural and Indigenous Affairs [2005] FCA 220 ('Illankovan'), counsel for the first respondent developed two further submissions with respect to the issue of the Stewart report, arguing, first, that the report was not simply corroborative (or consistent with) the first respondent's account of past events, but was evidence of his psychological presentation, to which the Tribunal had failed to advert. Thus, the first respondent submitted that the Stewart report was evidence that he presented as someone with a history of torture and trauma; and, for this reason, the authorities relied on by the appellant were distinguishable. Secondly, the Stewart report was, so the first respondent's counsel submitted, more than merely corroborative of the first respondent's claims, it was itself an integer of the claims being made.
28 1 would reject the first respondent's submissions for the reasons stated below.
29 First, I would reject the first respondent's submission that such evidence of his psychological presentation as is contained in the Stewart report can be regarded as an integer of the first respondent's claims. Accepting that the Stewart report was relevant to evidencing the first respondent's psychological condition, this condition was relevant either as to fitness to give evidence or as corroborative of the first respondent's claims to have suffered torture and trauma at the hands of the authorities in Bahrain on account of his political opinion and activities, and religion. The focus in this appeal was on this latter aspect, since this was the focus of the Federal Magistrate's reasons for judgment. From this perspective, the Stewart report was a piece of evidence with a purely corroborative function. It did not give rise to a new claim.
30 Secondly, I am not persuaded that the Tribunal failed to consider the corroborative effect of the Stewart report. Whilst not absolutely clear, the better view is that the Tribunal recognized that the psychological reports, including the Stewart report, were prepared on the basis that their authors accepted the first respondent's account of what had happened to him in Bahrain and that his psychological condition was consistent with his account. I do not consider that the first respondent's argument that the report evidenced his psychological presentation added anything to this analysis. As already noted, evidence as to the first respondent's psychological presentation was relevant either as to his fitness to give evidence or as corroborative of the first respondent's account. This evidence did not have any further relevance. The question of capacity did not arise; and, from the Tribunal's perspective, the corroborative effect of the psychological reports about the first respondent's condition was dubious once the Tribunal was minded to conclude, as it did for separate reasons, that it should reject the first respondent's account in material respects.
31 In substance, the Tribunal rejected the first respondent's claims because of its "major concerns" with the first respondent's account, which led the Tribunal to conclude that the first respondent was not a credible witness. Although I have not set out these concerns in these reasons, the Tribunal in fact explained them in some detail. In this circumstance, it was open to the Tribunal to determine that, in so far as the Stewart report and the other psychological reports tended to corroborate the first respondent's account, they were to be accorded little, if any, weight. Put another way, it was for the Tribunal to determine the weight to be given an expert psychologist's opinion, having regard to the other evidence before it that supported or undermined the supposed facts on which the opinion was said to be based: see Cong Tam Dang v Minister for Immigration & Multicultural Affairs (2000) 61 ALD 29 at 47- 48; [2000] FCA 73 at [83]-[87] (Drummond, Matthews and Mansfield JJ). In this case, the corroborative effect of the evidence constituted by the Stewart report (and the other psychological reports) was significantly diminished by the Tribunal's "major concerns" about the first respondent's account and, most particularly, its adverse finding about the first respondent's credibility. Such an approach does not disclose jurisdictional error: compare Minister for Immigration and Citizenship v SZNSP (2010) 184 FCR 485 at 491- 492 [35]-[40] (North and Lander JJ); and Re Minister for Immigration and Multicultural Affairs; ex parte Applicant S20/2002 (2003) 198 ALR 59 at 63 [12] (Gleeson CJ) and 70 [49] (McHugh and Gummow JJ).
32 In any case, even if the Tribunal had failed to take into account that the first respondent's claims of past persecution were consistent with the psychological condition set out in the Stewart report, there would have been no jurisdictional error. This failure would not amount to a failure to take into account a consideration that the Tribunal was bound to take into account. Rather, it would constitute a failure to address a piece of evidence before the Tribunal. As North and Lander JJ said in SZNPG at 309 [28] and [29]:
[A]n error of fact based on a misunderstanding of evidence or even overlooking an item of evidence in considering an applicant's claims is not jurisdictional error, so long as the error, whichever it be, does not mean that the RRT has not considered the applicant's claim.
In our opinion, the RRT did not fall into jurisdictional error in this case. It weighed a particular piece of evidence against other evidence, but was not persuaded by that particular piece of evidence enough to alleviate its concerns in relation to the whole of the first respondent's evidence.

33 The same approach had generally been adopted on other occasions where a failure to consider an expert psychologist's report has been alleged. For instance, in Subramaniam v Minister for Immigration and Multicultural Affairs [2002] FCAFC 255, a Full Court (constituted by Drummond, Cooper and Finkelstein JJ) considered whether an almost identical failure on the Tribunal's part in that case amounted to reviewable error and concluded that it did not. See also Thirukkumar v Minister for Immigration and Multicultural Affairs [2002] FCAFC 268; VMAJ v Minister for Immigration and Multicultural and Indigenous Affairs [2005] FCAFC 21 at [27]-[29]; VGAP v Minister for Immigration and Multicultural and Indigenous Affairs [2004] FCA 1607 at [34]; and Rezaei v Minister for Immigration and Multicultural and Indigenous Affairs [2001] FCA 1294 at [57].
34 In this context, I note that the first respondent relied on SZKHD v Minister for Immigration and Citizenship [2008] FCA 112. I am inclined, however, to consider that SZKHD turned very much on matters peculiar to it; and, in any event, stands outside the general run of authorities. It is relevant to note that, in SZKHD in contrast to this case, the Tribunal stated that it did not "question the conclusions of the applicant's mental health issues and [did] not question the conclusions of the treating psychologist", although it went on to reject the claims that were contained in the report: see SZKHD at [10]. In the current case, the Tribunal never accepted the conclusions of the Stewart report about the cause of the first respondent's psychological condition.
35 Further, I consider that the first respondent's reliance on Illankovan was misplaced. That case is clearly distinguishable from the present case. First, Illankovan concerned a Special Eligibility (Residence) (Class AO) visa, for which the Migration Regulations stipulated certain eligibility criteria. The Minister conceded that, if his Honour decided (as his Honour ultimately did) that the Tribunal had overlooked a particular report dealing with one criterion, then there was a constructive failure to exercise jurisdiction. This was presumably because it might reasonably be inferred that the Tribunal had failed to consider a statutorily-mandated criterion: see Illankovan at [55]. There was no failure to consider a statutorily-mandated criterion in this case.
