Consideration
29 I shall deal with the two remaining grounds in turn. Before doing so I make the following general observations.
30 First, in relation to both the two grounds as drafted and in relation to the general thrust of the submissions put on behalf of the appellant, it is not the common law that in every case where a party provides further material he or she must be given an opportunity to give evidence and make submissions if the decision maker is considering making use of the material in a manner adverse to the interests of the party providing it.
31 Second, in SZBEL the High Court said at [25] it was not to the point to ask whether the decision-maker's factual conclusions were right: the relevant question was about the decision-maker's processes, not his or her actual decision. The submissions on behalf of the appellant recognised this.
32 Although SZBEL concerned statutory procedures, particularly s 425(1) of the Migration Act, rather than the common law, further guidance is given by that decision about the identification of determinative issues. It will be recalled that the High Court held that the tribunal did not give the appellant a sufficient opportunity to give evidence, or make submissions, about what turned out to be, in that case, two of the three determinative issues arising in relation to the decision under review: see the judgment at [44]. The High Court said at [42]-[43] that the appellant was not on notice that his account of how his ship's captain came to know of his interest in Christianity, and his account of the captain's reaction to that knowledge, were issues arising in relation to the decision under review. The delegate, the primary decision-maker, had not based his decision on either of these aspects of the matter. Based on what the delegate had decided, the appellant would, and should, have understood the central and determinative question on the review to be the nature and extent of his Christian commitment.
33 Importantly for the present appeal, in SZBEL the High Court explained the relationship between what was or was not obviously open on the known material and the issue or issues critical to the decision as follows:
[38] When it is said, in the present matter, that the appellant was not put on notice by the Tribunal that his account of certain events would be rejected as "implausible", and that this conclusion was "not obviously … open on the known material", the focus of the contention must fall upon what was "obviously … open" in the Tribunal's review. That can be identified only by having regard to "the issues arising in relation to the decision under review". It is those issues which will determine whether rejection of critical aspects of an applicant's account of events was "obviously … open on the known material".
34 Third, I note what was said in Minister for Immigration and Citizenship v SZGUR (2011) 241 CLR 594 at [8]-[9] by French CJ and Kiefel J, with whom Heydon and Crennan JJ expressly agreed at [91] and [92] respectively:
[8] The "information" upon which the Tribunal invited comment, was the existence of "contradictions and inconsistencies" between what SZGUR had stated orally and in writing to the Tribunal, variously constituted, during the iterations of the review process. The contradictions and inconsistencies, which were elaborated at some length in the letter, related to SZGUR's claimed involvement with the Communist Party of Nepal, whether he and his family had gone into hiding in Nepal, whether he had been helped to leave the country and his claim that two colleagues had been executed by the Nepalese Army.
[9] Despite the language of the Tribunal's letter, the existence of "inconsistencies" and "contradictions" in an applicant's testimony and written submissions to the Tribunal is not "information" of the kind to which s 424A is directed. As was explained by the plurality in SZBYR v Minister for Immigration and Citizenship (2007) 235 ALR 609 at [18], the term "information" in s 424A does not extend to the Tribunal's "subjective appraisals, thought processes or determinations". Their Honours said:
"However broadly 'information' be defined its meaning in this context is related to the existence of evidentiary material or documentation, not the existence of doubts, inconsistencies or the absence of evidence."
The exclusion of this class of information from the obligation imposed by s 424A is consistent with limits on the procedural fairness hearing rule at common law. Procedural fairness requires a decision-maker to identify for the person affected any critical issue not apparent from the nature of the decision or the terms of the statutory power. The decision-maker must also advise of any adverse conclusion which would not obviously be open on the known material. However, a decision-maker is not otherwise required to expose his or her thought processes or provisional views for comment before making the decision. That is not to say that the Tribunal cannot or should not, in the exercise of its discretion, invite an applicant for review to make supplementary submissions in relation to apparent inconsistencies, contradictions or weaknesses in his or her case which have been identified by the Tribunal. Indeed it may be that such an invitation, once issued, amounts to a binding indication by the Tribunal that the review process will not be concluded until the applicant has had an opportunity to respond. . . .
(footnotes omitted)
35 It will be noted that their Honours expressly referred to the limits on the procedural fairness hearing rule at common law.
36 It follows, in my opinion, while recognising that whether an issue must be raised with a claimant for the purposes of a further hearing will depend on the circumstances of each case (Minister for Immigration and Citizenship v SZKTI (2009) 238 CLR 489 at [51]), in circumstances such as the present where the claimant, or the claimant through his or her adviser, submits material to the decision-maker after a hearing or interview it will be unlikely that that material gives rise to a critical issue not apparent from the nature of the decision. This is because, in most cases, that material will be directed to one or more such issues apparent from the conduct of the decision-making thus far.
37 I also note that in SZKTI the High Court considered a notice of contention raising the question whether the Tribunal had failed to comply with s 425(1) by not issuing a second invitation to appear before it to give evidence and present arguments regarding what were said to be additional issues arising from the Tribunal's telephone inquiries of a Mr Cheah, who was referred to as an elder of the Local Church. The Court said, at [51], that Mr Cheah's evidence was additional evidence about an extant issue; it did not constitute the raising of a new or additional issue such as to trigger the obligation to give another hearing. The extant issue was whether SZKTI had been an active Christian in China. Mr Cheah's knowledge of SZKTI's past activities in China deriving from any account given to him by SZKTI was directly related to that issue.
38 In the present case, therefore, a real question is whether the Reviewer reached any adverse conclusion which would not obviously be open on the material provided on behalf of the appellant having regard to the issues which had arisen. The use of that latter expression is, as I have indicated, immediately referable to the discussion of the statutory scheme by the High Court in SZBEL, and I use it by analogy in the present appeal which is concerned with the position at common law.
