ground 3
20 In support of ground 3, the appellant relies upon legal unreasonableness as the basis for asserting jurisdictional error.
21 Since the High Court's judgment in Minister for Immigration and Citizenship v Li (2013) 249 CLR 332, a number of Full Courts of this Court have considered the content of the requirement that administrative decisions be legally reasonable, which is to say that they must not be legally unreasonable: Minister for Immigration and Border Protection v Singh (2014) 231 FCR 437; Minister for Immigration and Border Protection v Stretton (2016) 237 FCR 1; and Minister for Immigration and Border Protection v Eden (2016) 240 FCR 158. In Eden, Allsop CJ, Griffiths and Wigney JJ summarised in seven points what falls from Li, Singh and Stretton, noting that the seven point summary does not supplant or derogate from those cases. The seven points are these (citations omitted):
[58] First, the concept of legal unreasonableness concerns the lawful exercise of power. Legal reasonableness, or an absence of legal unreasonableness, is an essential element in the lawfulness of decision-making.
[59] Second, the Court's task in determining whether a decision is vitiated for legal unreasonableness is strictly supervisory. It does not involve the Court reviewing the merits of the decision under the guise of an evaluation of the decision's reasonableness, or the Court substituting its own view as to how the decision should be exercised for that of the decision maker. Nor does it involve the Court remaking the decision according to its own view of reasonableness.
[60] Third, there are two contexts in which the concept of legal unreasonableness may be employed. The first involves a conclusion after the identification of a recognised species of jurisdictional error in the decision making process, such as failing to have regard to a mandatory consideration, or having regard to an irrelevant consideration. The second involves an "outcome focused" conclusion without any specific jurisdictional error being identified.
…
[62] Fourth, in assessing whether a particular outcome is unreasonable, it is necessary to bear in mind that within the boundaries of power there is an area of "decisional freedom" within which a decision-maker has a genuinely free discretion. Within that area, reasonable minds might differ as to the correct decision or outcome, but any decision or outcome within that area is within the bounds of legal reasonableness. Such a decision falls within the range of possible lawful outcomes of the exercise of the power.
[63] Fifth, in order to identify or define the width and boundaries of this area of decisional freedom and the bounds of legal reasonableness, it is necessary to construe the relevant statute. The task of determining whether a decision is legally reasonable or unreasonable involves the evaluation of the nature and quality of the decision by reference to the subject matter, scope and purpose of the relevant statutory power, together with the attendant principles and values of the common law concerning reasonableness in decision-making. The evaluation is also likely to be fact dependant and to require careful attention to the evidence.
[64] Sixth, where reasons for the decision are available, the reasons are likely to provide the focus for the evaluation of whether the decision is legally unreasonable. Where the reasons provide an evident and intelligible justification for the decision, it is unlikely that the decision could be considered to be legally unreasonable. However, an inference or conclusion of legal unreasonableness may be drawn even if no error in the reasons can be identified. In such a case, the court may not be able to comprehend from the reasons how the decision was arrived at, or the justification in the reasons may not be sufficient to outweigh the inference that the decision is otherwise outside the bounds of legal reasonableness or outside the range of possible lawful outcomes.
[65] Seventh, and perhaps most importantly, the evaluation of whether a decision is legally unreasonable should not be approached by way of the application of particular definitions, fixed formulae, categorisations or verbal descriptions. The concept of legal unreasonableness is not amenable to rigidly defined categorisation or precise textural formulary. That said, the consideration of whether a decision is legally unreasonable may be assisted by reference to descriptive expressions that have been used in previous cases to describe the particular qualities of decisions that exceed the limits and boundaries of statutory power. A number of those cases, and the descriptive expressions used in them, are referred to in Li and in the judgment of Allsop CJ in Stretton (at [5]). The expressions that have been utilised include decisions which are "plainly unjust", "arbitrary", "capricious", "irrational", "lacking in evident or intelligible justification", and "obviously disproportionate". It must be emphasised again, however, that the task is not an a priori definitional exercise. Nor does it involve a "checklist" exercise. Rather, it involves the Court evaluating the decision with a view to determining whether, having regard to the terms, scope and purpose of the relevant statutory power, the decision possesses one or more of those sorts of qualities such that it falls outside the range of lawful outcomes.
22 The appellant contended that the Tribunal rejected the credibility of his claims in large part because it rejected his claim that his uncle who was killed in 1991 and his uncle who was killed in 2008 while the appellant was present, had been killed for supporting the LTTE by supplying them with food and possibly supporting them in some other ways, or that the uncle killed in 2008 had been tortured in 2002. That claim was advanced at the Tribunal hearing but at no stage earlier in the process of the appellant's application for a visa. The Tribunal considered but rejected the appellant's explanation that he had not earlier mentioned the connection with the LTTE because he thought it might jeopardise his application for a visa because the LTTE was banned in Australia.
23 In its reasons, at [37], the Tribunal identified six factors for its finding that the appellant's claims that he was targeted after the death of his uncle in 2006 were not credible. One of the reasons given for that conclusion was the failure of the appellant to have raised, prior to the hearing at the Tribunal, the connection between his uncles and the LTTE. In that respect the Tribunal said this:
The applicant said in his statutory declaration that he did not know why any of his uncles had been killed or whether they had links to the LTTE and he said at the interview that he did not know why his uncle had been killed in 2006 which is directly contradictory to his claims at the hearing. In his interview and statutory declaration, the applicant did not mention that his uncle had provided food parcels to the LTTE or that his uncle had LTTE members hiding in his fields or that his uncle was detained by the authorities in 2002 and tortured. I do not accept the applicant's explanations that he did not mention any of these matters because he was worried that his application would be jeopardised. The applicant has been represented throughout the process and he did not claim that he personally or any other family member was involved in the LTTE and its activities (save for another uncle giving food to them way back in 1991).
24 There was nothing irrational about the Tribunal concluding that the appellant's failure to previously raise his uncles' connections with the LTTE impugned the credibility of his claim. The failure to raise an important integer of a claim in circumstances where earlier opportunities to do so had been available, and may reasonably have been expected to have been taken up, logically raises the prospect that the later raising of that integer is a product of recent invention. Additionally, to not have raised a matter at one stage of a process in circumstances where it is later raised at another stage of the same process suggests prior inconsistency. Inconsistency is a logical basis upon which credibility may be impugned. Of course, much will depend on the particular circumstances at hand.
25 The appellant contended that the Tribunal proceeded on the basis that a claim advanced later in the process before the Tribunal was not to be accepted. The suggestion here seems to be that that was done arbitrarily. An arbitrary approach of that kind may well constitute legal unreasonableness. But there is no basis for concluding that the Tribunal adopted such an approach. The fact that the Tribunal considered and weighed the explanation given by the appellant for not earlier mentioning the LTTE connections demonstrates that the Tribunal considered the prior inconsistency on its merits.
26 The appellant also complained that the Tribunal had only given one reason for rejecting his application, that reason being that he had been represented throughout the process. There is nothing illogical or irrational in the reliance placed by the Tribunal on the fact that the appellant had been legally represented throughout in the context of the appellant's explanation that he had not raised the LTTE connections because he was worried it would jeopardise his visa application. The fact that the appellant had access to legal representation throughout the visa application process makes it more likely that throughout that process the appellant would have been made aware, as he seems to have been aware at the hearing, that making the connections that he sought to make with the LTTE would not jeopardise his claim but would enhance it.
27 There was therefore a probative basis for the Tribunal to reject the appellant's explanation for why he did not raise the connection with the LTTE earlier. The Tribunal's approach did not lack evident or intelligible justification. I do not accept the appellant's contention that there needed to be "a highly probative basis" for that rejection. The weight to be accorded to the probative basis identified by the Tribunal was a matter for the Tribunal.
28 Furthermore, and in any event, the challenge made by the appellant is made in relation to one of six factors relied upon by the Tribunal for its conclusion that the appellant's claims were not credible. Even if the Tribunal was wrong to have relied on the factor that the appellant has challenged, the Tribunal's conclusion as to credibility was sufficiently supported by the other five factors upon which the Tribunal relied and which are recounted at [37] of its reasons. In that context any error in relation to the factor under challenge would not be jurisdictional: MZYYU v Minister for Immigration and Citizenship [2014] FCA 98 at [50] (Bromberg J).
29 There is, in my view, no appellable error in the judgment of the primary judge. Ground 3 must be rejected.
