Grounds 2 and 3
29 In the appellant's written submissions, he contended that the Tribunal had "mistakenly conflated two very distinct and separate organisations and the [appellant's] reasons to fear the CID and ASIO." The appellant submitted that his mention of the CID would not have raised security concerns in Australia as the CID officials were only interested in him due to his involvement in the case relating to his father's death. The appellant submitted that this fact would not raise concerns about his involvement with terrorist organisations and therefore would not raise security clearance concerns.
30 The appellant submitted that the Tribunal's finding was "arbitrary or lacking in proper engagement with the claims and evidence" and that "the Tribunal did not fully engage with the submissions in considering the claim".
31 The Minister submitted that "a rational and logical decision maker would find … that being wanted by the CID would be comparably relevant to Australia's security concerns as being a member of the LTTE." In relation to the Tribunal's conclusion in paragraph [86], the Minister submitted that the trial judge's finding that the Tribunal was not illogical or irrational was correct because "no submission had been made to the delegate that the appellant's father had been targeted because one of his sons was associated with the LTTE." He contended that the Tribunal's finding was not unreasonable for the same reasons. He added that the Tribunal had considered the appellant's explanation for the failure to disclose his brother's involvement with the LTTE to the delegate and had not accepted the appellant's submissions because of his preparedness to disclose the CID interest.
32 The appellant's written submissions were relied on and elaborated upon in oral argument. There was a notable disparity between the grounds as particularised and the submissions as they were developed.
33 As I understood this part of the appellant's case, as ultimately refined, it was focussed on the Tribunal's treatment of his failure to mention his indirect and perceived association with the LTTE when he originally explained his reasons for fearing persecution in Sri Lanka. He was later to attribute this failure to his concern that disclosure would excite an adverse security interest in him in Australia. The Tribunal had not believed this explanation because he had not felt a similar inhibition when he told the interviewer that he had attracted the interest of the Sri Lankan CID whilst in that country. This disbelief was one of a number of factors which led the Tribunal to conclude that the appellant was not a witness of truth and that he had had no LTTE affiliation.
34 The appellant contended that the Tribunal's reasoning was irrational and illogical and was unreasonable in the Wednesbury sense.
35 Complaints of this kind are not easy to make good in judicial review proceedings. The reviewing court must always be alert to substituting its own appreciation of the merits for that of the body to whom the legislature has committed the fact finding task: see Minister for Immigration and Border Protection v Stretton [2016] FCAFC 11 at [21] (Allsop CJ); [74]-[76] (Griffiths J). Although the Wednesbury unreasonableness ground of judicial review is well established the same cannot be said about complaints that a decision, or the reasoning which underpins it, is "illogical" or "irrational". It may be that there is a substantial, if not complete, overlap between the three grounds. Whether or not that be the case, an applicant who relies on such grounds in judicial review proceedings, must do more than persuade the reviewing court that another rational decision-maker might have emphatically disagreed with the reasoning process and findings of the person who made the impugned decision. As Crennan and Bell JJ observed in Minister for Immigration and Citizenship v SZMDS (2010) 240 CLR 611 at 647-8:
"In the context of the Tribunal's decision here, "illogicality" or "irrationality" sufficient to give rise to jurisdictional error must mean the decision to which the Tribunal came, in relation to the state of satisfaction required under s 65, is one at which no rational or logical decision maker could arrive on the same evidence. In other words, accepting, for the sake of argument, that an allegation of illogicality or irrationality provides some distinct basis for seeking judicial review of a decision as to a jurisdictional fact, it is nevertheless an allegation of the same order as a complaint that a decision is "clearly unjust" or "arbitrary" or "capricious" or "unreasonable" in the sense that the state of satisfaction mandated by the statute imports a requirement that the opinion as to the state of satisfaction must be one that could be formed by a reasonable person. The same applies in the case of an opinion that a mandated state of satisfaction has not been reached. Not every lapse in logic will give rise to jurisdictional error. A court should be slow, although not unwilling, to interfere in an appropriate case."
36 The High Court gave further attention to the relevant principles in Minister for Immigration and Citizenship v Li (2013) 249 CLR 332. French CJ said (at 351) that:
"After all the requirements of administrative justice have been met in the process and reasoning leading to the point of decision in the exercise of a discretion, there is generally an area of decisional freedom. Within that area reasonable minds may reach different conclusions about the correct or preferable decision. However, the freedom thus left by the statute cannot be construed as attracting a legislative sanction to be arbitrary or capricious or to abandon common sense."

37 When he appeared before the Tribunal the appellant placed considerable reliance on his apprehension that he would be perceived by Sri Lankan authorities as an LTTE sympathiser. He had made no mention of such a concern when he first made his application for a protection visa. He did, however, disclose to the Minister's delegate that he had been subject to attention by a Sri Lankan security agency, the CID. It was in these circumstances that the Tribunal did not accept his explanation for not having mentioned his concern about being perceived as an LTTE sympathiser and treated this belatedly-made claim as a recent invention. Neither the Tribunal's reasoning process nor its conclusion can be regarded as being so unreasonable that no reasonable person could have proceeded as the Tribunal did. It was neither irrational nor illogical for the Tribunal to question the apparent inconsistency of the appellant's willingness to tell the Tribunal about his adverse dealings with the CID while not saying anything about his brother being an LTTE fighter because of an avowed fear of exciting the unwelcome interest of Australian security authorities.
38 It was necessary for the Tribunal, in performing its duties, to form a judgment as to the credibility of the appellant's claims. Its assessment and the conclusion to which that assessment led were within the area of decisional freedom conferred on the Tribunal. While different decision-makers may have placed a different complexion on the appellant's failure, initially, to tell the interviewer about the appellant's brother's alleged association with the LTTE, it cannot be said that no reasonable person would have approached the issue in the same manner. It is also to be borne in mind that the adverse credit finding, ultimately made by the Tribunal, was not informed solely by the appellant's delay in raising the suggestion that he may, indirectly, be tarred with the LTTE brush.
39 These grounds have not been made out.
