The Tribunal's obligations
46 The Tribunal was obliged, upon the appellants having made the Review Application, to review the Minister's Decision: the Act, s 414(1). Doing so required, in effect, that it assume the position previously occupied by the Minister's delegate and consider, for itself, whether the Visa Application should be granted: the Act, ss 65 and 415.
47 The Visa Application turned upon whether or not the Tribunal, in conducting the review that it was obliged to conduct, was satisfied that the appellants met any one or more of the criteria specified in s 36 of the Act. If it was satisfied that they did, then it was obliged to set aside the Minister's Decision and grant the appellants' Visa Application. If (as was ultimately the case) it was not satisfied that they did, then it was obliged to affirm the decision not to grant the Visa Application. The Tribunal's statutory task, then - like that of the Minister before it - was to consider whether or not it was satisfied as to the existence of a particular state of affairs: specifically, that the appellants met one or more of the criteria for which s 36 of the Act provided.
48 In order that it might attain or not attain that state of satisfaction, the Tribunal was plainly obliged to consider what might happen to the appellants (and, in particular, the first appellant) in the event that they (and he) returned to Pakistan. It could not determine whether the first appellant possessed a relevant fear (or was otherwise subject to a relevant risk) of harm without doing so. Plainly, divining what the future might hold was a task that called for some informed speculation. As is to be expected, its execution involved a question in respect of which evidence and submissions were received. Those materials touched upon events that were said to have occurred in the past (namely, whether or not the TTP had mistaken the first appellant for a spy and had threatened his life accordingly). Again, that those materials would traverse that territory is hardly surprising. The foundation for the fears that the appellants said that they held regarding what might happen to them if they returned to Pakistan was inevitably informed by what they said had happened to them (or, more particularly, to the first appellant) in the past: Minister for Immigration and Ethnic Affairs v Guo (1997) 191 CLR 559 ("Guo"), 575 (Brennan CJ, Dawson, Toohey, Gaudron, McHugh and Gummow JJ); Minister for Immigration and Multicultural Affairs v Rajalingam (1999) 93 FCR 220, 237 [53] (Sackville, North and Kenny JJ). The Tribunal could not lawfully discharge its task unless it was conscious of - and gave consideration to - the materials that the appellants advanced in that respect: Minister for Immigration and Border Protection v MZYTS (2013) 230 FCR 431 (Kenny, Griffiths and Mortimer JJ).
49 The Act does not, in terms, impose upon the Tribunal an obligation to make any particular findings. Clearly in this case, the Tribunal could not discharge its statutory task without at least finding that it was or was not satisfied that the appellants met one or more of the criteria for which s 36 of the Act provides. Such a finding - and any others that went to what the Tribunal considered were material questions of fact - required expression in the Tribunal's written decision: the Act, s 430(1); Minister for Immigration and Multicultural Affairs v Yusuf (2001) 206 CLR 323, 346 (McHugh, Gummow and Hayne JJ). If it failed to record in its reasons the conclusions that it drew, and the evidence or other material upon which it drew them, then the Tribunal risked being thought to have not made them and, potentially thereby, to have overlooked matters that it was obliged to consider. That, in turn, would expose it to a charge that it had failed to perform the statutory task with which it was entrusted: Minister for Home Affairs v Buadromo (2018) 362 ALR 48 ("Buadromo"), 59 [47] (Besanko, Barker and Bromwich JJ).
50 The appellants maintain that the Tribunal was obliged to make (and state) a finding as to whether or not the TTP Letters were authentic. Heavy reliance was placed to that end upon the decision of this court in NAQG v Minister for Immigration and Multicultural and Indigenous Affairs [2004] FCA 1631 ("NAQG") (Allsop J). There, the court set aside a decision of the Refugee Review Tribunal by which an application relevantly identical to the one presently under consideration was declined. The appellants were a family of Bangladeshi citizens. The husband and wife appellants, who claimed to have been politically active in Bangladesh, sought protection on the basis that they would be persecuted in their homeland because of that activism. In support of that claim, the husband claimed that he had been falsely charged with some offences in Bangladesh and tendered some documents that he said established as much. Country information available to the Tribunal suggested that false documentation of the kind upon which the appellants relied was easily obtained. In rejecting the applicants' claims, the tribunal concluded that the husband had not, in fact, been falsely charged. However, save for a summary reference to having received them, it said nothing about the documents upon which the appellants had relied to establish that proposition. Allsop J observed (at [17]):
[T]he issue as to whether the Tribunal completed its jurisdictional task arises if it can be seen to have decided a fact without addressing material before it which, on its face, contradicted the conclusion that it was otherwise minded to draw and which it expressed.
Later, at [41]-[42], his Honour stated:
If the Tribunal has not made a finding about the documents in question it has failed, in my view, to complete its jurisdictional task. It simply cannot conclude that there are no false charges only upon disbelieving the first appellant's evidence, without making a finding upon documents which on their face prove the fact that there are such charges.
…
[T]he evidence, which is not merely corroborative, but on its face documentary evidence negating of the fact otherwise found, was not dealt with.
(emphasis added)
51 For obvious reasons, the appellants point to the words emphasised above. So the submission proceeds, they reflect that the Tribunal was obliged to state in its reasons either that the TTP Letters were or were not authentic; and that its failure to do so amounts to a failure to understand and properly discharge the statutory function with which it was entrusted.
52 The language employed in NAQG - referring, as it does, to the Tribunal "making a finding" - is not limited to that authority. In Guo, the majority (Brennan CJ, Dawson J, Toohey J, Gaudron J, McHugh J and Gummow JJ) discussed the need, in cases such as the present, for the Tribunal to engage in what I have described above as "informed speculation" about what might happen to a visa applicant if he or she is returned to his or her country of origin. At 575, it said:
In many, if not most cases, determining what is likely to occur in the future will require findings as to what has occurred in the past because what has occurred in the past is likely to be the most reliable guide as to what will happen in the future. It is therefore ordinarily an integral part of the process of making a determination concerning the chance of something occurring in the future that conclusions are formed concerning past events. In the present case, for example, the Tribunal correctly relied on what it found had happened to Mr Guo and others to make a finding that he was not "differentially at risk for a Convention reason." Without making findings about the policies of the Chinese authorities and the past relationship of Mr Guo with those authorities, the Tribunal would have had no rational basis from which it could assess whether there was a real chance that he might be persecuted for a Convention reason if he were returned to the PRC.
(emphasis added)
53 The authenticity of the TTP Letters was a matter that, together with others, was capable of informing the Tribunal's assessment of whether or not the TTP had accused the first appellant of spying and, for that reason, had threatened his life. That was an issue of the sort to which the High Court in Guo referred in the passage cited above: it was one that called for a conclusion (that is to say, a "finding") as to the occurrence of a past event (namely, whether the first appellant's life had been threatened) in order that an assessment might be made of the likelihood of a future event (namely, that the first appellant would be subjected to relevant persecution or harm were he to return to Pakistan). Questions arising in respect of the evidence and submissions that informed that conclusion, however, would not themselves qualify as questions of material fact.
54 I do not read either NAQG or Guo as requiring that the Tribunal make and record findings on intermediate factual or evidential issues. On the contrary, I consider that the law is clear that it is under no such obligation. A finding of fact "…may not be required if the claim or issue is irrelevant or if it is subsumed within a claim or issue of greater generality": Buadromo, 59 [46] (Besanko, Barker and Bromwich JJ); see also Applicant WAEE v Minister for Immigration and Multicultural and Indigenous Affairs (2003) 236 FCR 593, 604-605 [46]-[47] (French, Sackville and Hely JJ).
55 Further and more significantly, the weight to be given to the evidence about a particular fact is a matter for the Tribunal: Abebe v The Commonwealth (1999) 197 CLR 510, 580 [197] (Gummow and Hayne JJ); Minister for Immigration and Citizenship v SZJSS (2010) 243 CLR 164 ("SZJSS"), 176 [33] (French CJ, Gummow, Hayne, Heydon, Crennan, Kiefel and Bell JJ).
56 Whether or not the TTP Letters were or were not authentic was not dispositive of the Tribunal's review of the Minister's Decision. It would have been open to the Tribunal to find that they were authentic but that the first appellant nonetheless did not satisfy one or more of the criteria upon which his Visa Application turned (for example, because he might reasonably avoid the risks that they foreshadowed by relocating to another part of Pakistan); or even, alternatively (although perhaps less likely), that he did notwithstanding that they were fakes. The weight (if any) to be given to the TTP Letters was a matter for the Tribunal: SZJSS, 176 [33] (French CJ, Gummow, Hayne, Heydon, Crennan, Kiefel and Bell JJ). Subject to the principles of legal unreasonableness (with which this ground of appeal does not engage), the Tribunal could attribute to the TTP Letters whatever significance it considered was appropriate. It was obliged only to take account of them in forming the view that it formed about whether or not the first appellant had been threatened in the way that he claimed (and, more broadly, whether he was able to satisfy one or more of the criteria upon which his Visa Application turned).
57 To speak of its obligation to "take account" of the TTP Letters is to do no more than to recognise that the Tribunal was obliged to engage in an "active intellectual process" directed to the issue or question in respect of which the appellants advanced them: Tickner v Chapman (1995) 57 FCR 451, 462 (Black CJ), 476-477 (Burchett J), 495-496 (Kiefel J); Carrascalao v Minister for Immigration and Border Protection (2017) 252 FCR 352, 364 (Griffiths, White and Bromwich JJ); Lafu v Minister for Immigration and Citizenship (2009) 112 ALD 1, 7 (Lindgren, Rares and Foster JJ); Telstra Corporation Ltd v ACCC (2008) 176 FCR 153, 181-182 (Rares J). The Tribunal was obliged to recognise that the TTP Letters were advanced in support of the appellants' contention that the TTP had threatened the first appellant; and then, conscious of that reality, to turn its mind to whether or not the TTP Letters warranted acceptance of that claim.
58 There is not any real doubt that the Tribunal in this case turned its mind to - that is to say, engaged in an active intellectual process regarding - what should be made of the TTP Letters. Its reasons contained several references to them and exposed a clear consciousness of their significance to the appellants' Visa Application (namely, that they supported the appellants' contention that the TTP had mistaken the first appellant for a spy and had threatened him accordingly). The Tribunal evidently did not consider that the TTP Letters, viewed under the light of other considerations, were sufficient to warrant acceptance of that contention. Whether that was because it considered that they were fake was not stated (although it is difficult to envisage any other explanation). But, regardless, the Tribunal was not obliged to form or state a view on that, nor to explain "…the sub-set of reasons why it accepted or rejected individual pieces of evidence…": Buadromo, 59 [48] (Besanko, Barker and Bromwich JJ); Re Minister for Immigration and Multicultural Affairs; Ex parte Durairajasingham (2000) 168 ALR 407, 423 [67] (McHugh J). Subject to the principles governing legal unreasonableness - which, as already identified, are not engaged by this ground of appeal - it was for the Tribunal to determine what weight it gave to the evidence, including the TTP Letters, that informed its conclusion that the first appellant had not been mistaken for a spy or relevantly threatened.
59 The conclusion expressed in the previous paragraph, it must be conceded, is not easily reconciled with the conclusion that Allsop J reached in NAQG. Although his Honour, clearly enough, was concerned in NAQG about the lack of a "finding" as to the authenticity of the corroborative documentary evidence advanced in that case, other parts of his reasons expressed that concern in different terms. For example, at [17], his Honour observed that "...the issue as to whether the Tribunal completed its jurisdictional tasks arises if it can be seen to have decided a fact without addressing material before it which, on its face, contradicted the conclusions that it was otherwise minded to draw and which it expressed" (emphasis added). At [42], he summarised the Tribunal's error as having "not dealt with" evidence that was "…not merely corroborative, but [that was] on its face documentary evidence negating of the fact otherwise found". In those senses, his Honour can be understood to have decided the matter on the basis that the Tribunal had failed to engage in an "active intellectual process" directed to the factual issue in respect of which the documents were advanced, namely whether or not the husband appellant in that case had been falsely charged with offences in Bangladesh.
60 In any event, subsequent authorities, both in this court (Buadromo) and the High Court (SZJSS), establish that, subject to the principles of legal unreasonableness, the weighing of evidence is a matter for the Tribunal and that it is under no obligation to state why it was minded to accept or reject discrete aspects of the evidence advanced before it.
