13 It is convenient to look at the first two grounds together.
14 The case was argued before Mansfield J and before this Court on the basis that the affidavit material sought to be read before Mansfield J was "fresh evidence" admissible under s 27 of the Federal Court of Australia Act 1976 (Cth) which provides:
"In an appeal, the Court shall have regard to the evidence given in the proceedings out of which the appeal arose, and has power to draw inferences of fact and, in its discretion, to receive further evidence, which evidence may be taken:
(a) on affidavit; or
(b) by video link, audio link or other appropriate means in accordance with another provision of this Act or another law of the Commonwealth; or
(c) by oral examination before the Court or a Judge; or
(d) otherwise in accordance with section 46."
15 This misunderstands the position. Mansfield J was exercising original jurisdiction (subs 19(2) of the Federal Court of Australia Act). The Court has the power to receive further evidence in relation to such jurisdiction, providing that the evidence is relevant. With the leave of the Court, this can include affidavit evidence (see O 54B r 7 of the Federal Court Rules).
16 The question is one of relevance. Mansfield J rejected the evidence on the basis that it was not relevant. His Honour gave a number of reasons for this. It is sufficient to mention one. His Honour found that the evidence was not relevant because it would not and did not establish that there was no evidence or other material before the Tribunal to support its finding. According to Mansfield J:
"The proposed further evidence, in addition, would not demonstrate in any event that there was no evidence upon which the Tribunal could have reached the conclusion which it did. If accepted as reliable evidence, it would clearly bear directly and heavily upon the conclusion as to the applicant's nationality. The Tribunal may have wished to have the two witnesses available for questioning, to assess the reliability of their affidavits. It may have formed an adverse view as to the reliability of what each of them said. Neither professed to have had long exposure to the applicant. One said he had seen the applicant only once, some years before when he was only about 15 years of age. The other had never had contact with the applicant, but said he had seen him from time to time in the local bazaar. But, more importantly, the other evidence upon which the Tribunal did reach its conclusion (subject to considering the further grounds of review) remains unimpeached. The linguistic analysis report provides some evidence upon which the conclusion of the Tribunal about the applicant's nationality could have been reached. The proposed further evidence therefore would not establish that there was no evidence upon which it could have reached that conclusion. The Tribunal's observations about why it regarded the applicant as an unreliable witness also are capable of leading it to the conclusion it reached, and would retain that character notwithstanding the proposed further evidence. There was thus material upon which the conclusion of the Tribunal might have been based, notwithstanding the proposed new evidence; …"
In reaching this conclusion, Mansfield J has read the requirements of par 471(1)(g) as being requirements that must be met in order for an appellant to succeed on this review, in addition to meeting the requirements of par 471(4)(b).
17 The High Court has recently considered the meaning and effect of par 476(1)(g) of the Act in Minister for Immigration and Multicultural Affairs v Rajamanikkam (2002) 190 ALR 402 ("Rajamanikkam"). It is not altogether clear what ratio can be gleaned from that case as it affects this case. However, the individual Justices of the Court did consider the interrelationship of pars 471(1)(g) and 471(4)(b).
18 Gleeson CJ (at [34] and [41]) placed emphasis on par 471(1)(g)). So, His Honour explained, compliance with subs 471(4), whilst necessary, was not sufficient. Ultimately, it was necessary to establish the ground of appeal under subs 471(1). Callinan J took the same approach (at [151]):
"Subsection (4) was obviously not intended to expand the basis for review for which subs (1)(g) provided. This is clear from the opening words of the provision which employ the negative expression, 'the ground ... is not to be taken to have been made out unless ….' (emphasis in original). A different interpretation might have been available had the subsection been expressed in the affirmative to suggest that one, but perhaps not the only basis for the application of s 476(1)(g) would be, the making of a decision based on a non-existent fact. Subsection (4) stated:
The ground specified in paragraph (1)(g) is not to be taken to have been made out unless:
…
(b) the person who made the decision based the decision on the existence of a particular fact, and that fact did not exist.'"
On the other hand, Gaudron and McHugh JJ, in a joint judgment at [54], could see:
"… no reason why the 'no evidence' ground should not be approached …. on the basis that it is a discrete ground of review, the precise content of which is identified by the succeeding paragraphs of subsection (4)."
Clearly enough, they placed the emphasis upon par 471(4)(b) as identifying the entire content of par 471(1)(g). It would also seem clear that Gaudron and McHugh JJ accepted that their interpretation of the meaning of the relevant provisions would result in merit review, at least within the parameters of a "critical fact" (at [47]-[58]). If the approach of Gaudron and McHugh JJ represented the view of the Court, then it would seem clear that Mansfield J was in error in holding that the evidence should not be admitted on the balance of relevance.
19 The approach of Kirby J is more difficult to characterise. He said at [111] - [112]:
"… [A]s I would read the interaction of s 476(1)(g) with s 476(4), the latter is not a qualification of the application of the 'primary' requirement for judicial review stated, as such, in s 476(1)(g), so much as a statement of the content of that application, that is, an exposition of the particular circumstances in which, for these statutory purposes, a 'no evidence' ground is taken to apply. Viewed in this light - which appears to be the way Mason CJ treated the ADJR Act equivalent ground in Bond - the statutory 'no evidence' ground of judicial review is both wider and more specific than was the case with 'no evidence' grounds for judicial review at common law. This does not read s 476(1)(g) out of the Act. It simply gives that paragraph particular content. So much is made clear by the words of s 476(4) themselves. The ground specified in para (g) of s 476(1) is not to be taken to have been made out unless the requirements of paras (a) or (b) of s 476(4) are satisfied. So far as operative effect is concerned, therefore, s 476(1)(g) has none unless one of the two points in s 476(4) is satisfied.
… there is nothing offensive to the provision of relief by way of judicial review in interpreting s 476(4)(b) of the Act to cover a decision based on a 'particular fact' so long as that fact is not some inconsequential or minor fact or item of evidence on the way to reaching the 'decision' in question." (references omitted)
Paragraph [119] of the decision is of like effect. As Mr Tilmouth QC argued and Ms Maharaj appeared to concede, this would seem to be consistent with the approach of Gaudron and McHugh JJ.
20 However, his Honour's comments need to be understood in the context of what his Honour had to say at [113]:
"It does not involve an undue intrusion of the judiciary into the fact-finding processes of an administrative decision-maker to conclude that where, say, a critical fact is found to exist without any foundation in evidence or other material, the judge, supervising the administrative decision-making process for legal error, will set aside such a flawed decision and require it to be made again, freed from such an error. As Deane J indicated in Bond, where a reviewable decision made under a statute by a repository of statutory power is not supported by some probative material properly before the decision-maker, the 'decision', resting on such a foundation, will be invalid. In earlier times, at common law, this would have been explained by resort to the fiction that the parliament could not have 'intended' that a conclusion reached, resting on a mistaken view as to the existence of a critical fact, would be a 'decision' of the kind for which it had provided. The judge ordering review is confined to a proper and limited role. He or she does not substitute a decision on the facts or an opinion on the merits of the evidence for that made by the repository entrusted with such functions. All that is done is to set aside the flawed 'decision' and to require that a true 'decision' be reached without a disqualifying basis resting on the existence of a particular fact which the applicant for relief can show did not exist." (references omitted)
Similarly, at [120]-[121] Kirby J commented:
"The Full Court correctly stated that whether or not a finding as to the credibility of an applicant for a protection visa was a finding of a 'particular fact' would depend on the circumstances of the particular case.And that an applicant would still have to surmount the two hurdles established by the terms of s 476 of the Act as it stood at the relevant time:
· The decision-maker must have 'based' the decision in the existence of the particular fact rendering it, as it is sometimes described, 'critical' in the circumstances; and
· The applicant must be able to show that the fact did not exist, that is, that there was no evidence or other material concerning the fact before the decision-maker 'to justify the making of the decision'.
… In using the wording 'particular fact', it is suggested that something more 'particular' and 'factual' than the decision on the ultimate fact in issue was contemplated by the terms of s 476(4) . Yet it still had to be a 'particular fact' upon which the decision-maker 'based the decision' and the consideration that that fact did not exist had to be such as to deprive the 'decision' of the tribunal of evidence or other material justifying its making." (references omitted)
It would seem from this that Kirby J would interpret the relevant "fact" to be a fact which is "critical" and for which there is no "foundation in evidence or other material". Although this bears a similarity to the position of Gaudron and McHugh JJ, it is, nevertheless, fundamentally different to it. Indeed, the result would seem to be there is a majority comprising Gleeson CJ, Kirby and Callinan JJ that evidence cannot be called to prove that a fact did not exist for the purposes of subs 471(4) unless there was "no foundation in evidence or other material" before the Tribunal for that fact. This seems consistent with the clear view of each of those Justices that the relevant provisions do not provide for "merit review".
21 On our understanding of the majority position of the High Court in Rajamanikkam, it confirms the approach taken by Mansfield J. It confirms that this Court cannot interfere with a decision of the Tribunal unless it can be shown either that there was no evidence before the Tribunal to support that decision or, at least, that any further evidence as may be received has the necessary consequence that there is no remaining evidence to support the Tribunal decision.
22 In this case, the fact that there was evidence before the Tribunal upon which it could base its decision necessarily meant that the affidavit evidence sought to be read in this Court was not relevant to any issue before this Court. Mansfield J was correct to reject it.
