17 Finally, his Honour referred to what he described as "two forceful passages" involving lengthy, multi-barrelled questions put by the Tribunal to the respondent as supporting his view that the Tribunal was not open to be persuaded that the respondent did have a genuine commitment to the marriage at least at about the time it took place, ie, at about the time he made the visa application now in question.
18 It is apparent that the Tribunal had perused a range of material, as it was entitled to, before embarking upon the oral hearing. It is understandable, in view of the respondent's record of persistent deceit in his dealings with the Immigration Department from 1989 onwards, that the Tribunal would, as it undoubtedly did, approach the evaluation of the evidence he gave to it with very considerable scepticism. It is also understandable that a decision-maker, confronted with what it could well regard as the respondent's willingness to lie blatantly to it, might not only determine not to accept his evidence on anything, but might also feel (and display) some affront at being invited to accept the respondent's protestation of constant truthfulness. Such a response by a tribunal to that kind of conduct by a litigant will not ordinarily provide evidence of apparent bias, let alone of actual bias: see Galea v Galea (1990) 19 NSWLR 263 at 279 - 280 and 283.
19 But, as the learned primary judge observed, rejection of the respondent's own evidence that he had a genuine commitment to the marriage at its inception, ie, at about the date of his application for the visa now in question, could not, of itself, conclude the case against the respondent; yet that is how the Tribunal disposed of the case.
20 When a Tribunal has to assess whether a class 820 visa applicant meets the primary criteria of being "the spouse of an Australian citizen" and, in particular, whether it is satisfied, in terms of the definition of spouse in reg 1.15A(1)(b), that the two persons have a mutual commitment to a shared life as husband and wife and that the relationship between the two persons is genuine and continuing at both visa application date and date of decision, the credibility of the visa applicant, in asserting the existence of such a commitment and such a relationship, is of very considerable importance. But it is not necessarily decisive on either of these issues. Depending on the nature and extent of evidence coming from sources other than the applicant from, eg, his wife, relatives and acquaintances, a decision-maker adopting a proper approach to the visa entitlement claim may determine that the claim should succeed even though it rejects the evidence of the visa applicant himself as lacking credibility.
21 It was submitted by counsel for the appellant that, since the respondent's commitment to and the genuineness of his relationship with his wife at the relevant dates and, in particular, at the date of visa application, depends upon his own subjective state of mind, a finding adverse to the applicant's credibility must necessarily be fatal to his visa application. That is a surprising suggestion. Civil and criminal courts habitually perform the task of making necessary findings as to a particular person's subjective state of mind in a wide variety of forensic contexts. It is an entirely orthodox approach for a court or tribunal charged with finding the facts to take into account, in determining whether to make a particular finding as to a person's state of mind at a particular time, not only the evidence of the person as to what his state of mind was at the relevant time, but also the observations of anything that other witnesses saw and heard, that are also relevant to whether the person had the particular state of mind at the time in question.
22 Far from there being anything special in migration cases barring the decision-maker from taking this orthodox approach to fact finding when a Tribunal has to consider the nature of a visa applicant's own commitment to and relationship with his spouse, this truism of forensic fact finding is entrenched in the definition of "spouse" in reg 1.15A of the Migration Regulations. Far from treating evidence extraneous to the visa applicant's own testimony as irrelevant to proof of the nature of his own commitment to and relationship with his spouse, reg 1.15A(3) identifies classes of evidence from sources other than the applicant which are logically relevant to proving his state of mind on those issues and compels the decision-maker to have regard to such classes of evidence: sub-reg (3) provides that, "in forming an opinion for the purposes of par 1(b) … in relation to an application for a visa of sub-class … 820 …, the Minister must have regard to all the circumstances of the relationship including, in particular …", the various considerations set out in that sub-regulation.
23 In the context of this case, reg 1.15A(5) is also worthy of note. The respondent married his wife on 4 November 1995. At the date of the initial decision refusing his visa, the marriage had lasted over two years. At the date the Tribunal gave its decision, the date which the Tribunal considered was the relevant one so far as the criteria in par 820.22 are concerned, the marriage had lasted three and a half years. The ordinary approach to fact finding would suggest that the longer a marriage has in fact continued, the more ready will a decision-maker charged with the task of assessing whether it was a genuine one from its outset be to draw that conclusion. It is exactly that approach to proof of the issue in reg 1.15A(1)(b) of genuine and continuing relationship between visa applicant and spouse that is implicit in reg 1.15A(5). This sub-regulation creates something in the nature of a statutory presumption of the existence of a genuine marital relationship between the visa applicant and spouse, where they have cohabited for at least six months: such cohabitation is taken to be "strong evidence" that the relationship is genuine and continuing. This sub-regulation is so worded as to suggest that where the decision-maker has to decide whether a genuine marital relationship existed between a visa applicant and spouse who were together at a particular date, if at the time the question arises for determination the applicant and spouse have been together for six months (or more) that is to be taken as strong evidence that they were in a genuine and continuing relationship at the relevant date. To read this sub-regulation as the respondent would as making six months' (or more) cohabitation strong evidence of a genuine and continuing relationship at a particular date only if the minimum six months' period had already passed by that date involves an unwarranted gloss on what we regard as the clear words of the sub-regulation.
24 The Tribunal had a mass of material from sources external to the applicant that was capable of establishing the genuineness at relevant dates of the respondent's commitment to and relationship with his wife, ie, to show that he could satisfy the relevant criteria at both relevant dates. This material appears to have been gathered by the respondent's advisers with reg 1.15A(3) in mind in so far as it specifically deals with most of the matters therein listed. The Tribunal noted the existence of this body of oral and documentary evidence and even expressly accepted the reliability of some of the oral evidence. Yet it entirely ignored the significance of this evidence as probative of the respondent's commitment to the marriage when he entered into it because the Tribunal was not prepared to look beyond the respondent's own testimony.
25 The respondent's wife gave evidence to the effect that there was a genuine marriage bond between her and the respondent and a genuine parental relationship between the respondent and her child of a previous marriage. The Tribunal accepted her as an honest witness and considered that she had made a genuine commitment to him. But it dismissed her evidence on the basis that "this cannot save this application because the commitment has to be mutual both at the date of primary application and as at today's date" and it was not satisfied that the respondent had such a commitment at the date of his visa application in November 1995, just after the marriage, though it accepted that such a commitment may have come to exist by the time of the hearing before it. This, as the learned primary judge noted, treats the evidence of the respondent's wife of the observations she made and the opinions she expressed that were directly relevant to and probative of his commitment to the marriage at about the time it took place as irrelevant to that issue.
26 The Tribunal also noted that, in addition to the wife's evidence, "there are a lot of supporting documentation on file including statements from friends and relatives, bank statements, copies of lease and other documents". But that is all the Tribunal member had to say about that quite substantial body of evidence. This documentation includes much material evidencing the existence of assets jointly owned and financial liabilities jointly assumed; it includes statements by persons acquainted with the respondent and his wife attesting to their observations reaching back to mid 1996, though mostly confined to the period from early 1998, of there being a real family relationship between the respondent, his wife and her child. There is much in this body of material relevant to whether the respondent and his wife had a mutual commitment to a shared life and a genuine and continuing relationship with each other throughout the period covered by this material. It was directly relevant to whether those two criteria were satisfied, not only at the date of the decision, but also at the date of the visa application. Yet the Tribunal, apart from merely noticing the existence of this material, ignored its probative significance.
27 We do not accept that the comment it made in its reasons for decision about there being insufficient evidence to persuade it that the respondent's commitment to his marriage was genuine as at the date of the primary application was, as counsel for the appellant submitted, the Tribunal's elliptical assessment that this material did not satisfy it of the genuineness of the respondent's commitment to the marriage from its start. Not only did the Tribunal not indicate that it appreciated the relevance of this material to its task of assessing the nature of the respondent's commitment to and relationship with his wife at the earlier of the two relevant dates, but, in the immediately preceding passage in its reasons, it identifies unequivocally its rejection of the credibility of the respondent as the justification for its conclusion that he did not have a genuine commitment as at the date of visa application. Moreover, in the course of the hearing, the Tribunal commented on this mass of material indicating that it considered it was relevant only to whether, at the time of the hearing, the respondent had a genuine commitment to his wife. After stating that it was prepared to treat what he told the Departmental Officer at the interview on 5 December 1995 about not being married as a truthful statement and then giving the respondent opportunity to explain why he lied on that occasion, the Tribunal made these comments:
