4.2 Consideration
10 In order to amount to jurisdictional error, alleged "illogicality" or "irrationality" requires that the decision of the Authority is one at which no rational or logical decision-maker could arrive on the same evidence: Minister for Immigration and Citizenship v SZMDS [2010] HCA 16; 240 CLR 611 at [130] (Crennan and Bell JJ). Emphatic disagreement with the reasoning is not enough: SZMDS at [129] and [132]. The question is whether it was open to the Authority to engage in the process of reasoning in which it did engage and to make the findings that it did make on the material before it: SZMDS at [133]. As Crennan and Bell JJ observed at [135]:
…a decision will not be illogical or irrational if there is room for a logical or rational person to reach the same decision on the material before the decision maker. A decision might be said to be illogical or irrational if only one conclusion is open on the evidence, and the decision maker does not come to that conclusion, or if the decision to which the decision maker came was simply not open on the evidence or if there is no logical connection between the evidence and the inferences or conclusions drawn.
11 The statutory context for the decision of the Authority includes s 473FA(2) of the Act which, as the primary judge noted, provides:
The Immigration Assessment Authority, in reviewing a decision, is not bound by technicalities, legal forms or the rules of evidence.
12 The reasoning of the Authority included a summary of the several statements provided by the appellant during the course of the processing of his application for a SHEV. This involved consideration of the content of his arrival interview on 25 October 2012, an enhanced screening interview conducted on 28 November 2012, a SHEV interview on 17 June 2016, a statutory declaration dated 15 February 2015 and a statutory declaration dated 6 September 2017.
13 On 28 August 2017 the appellant received a letter from the Department of Immigration and Border Protection indicating that it had conducted checks to confirm the information that he had provided in the course of his application and that a delegate of the Minister considered that information given during his enhanced screening interview did not support his protection visa claims. The record of the enhanced screening interview was attached to this letter.
14 The appellant submits that the ASETTS letter was supplied to the delegate in response to that letter in order to support the appellant's claim, advanced in his statutory declaration of 6 September 2017, that he struggles to remember exact dates due to his mental health. In submissions before the Authority the appellant emphasised these difficulties. He submits that after the Authority had reviewed various inconsistencies and incongruities arising from his interviews and declarations, the Authority ought to have considered the chance that his account of events, and his ability to be consistent with dates between interviews conducted years apart, might have been adversely affected by his claimed post-traumatic mental condition. He submits that the dismissal by the Authority of the ASETTS letter, and its treatment of the letter as not being corroborative of his claim that he struggled with his memory, resulted in it placing excessive emphasis on those inconsistencies.
15 For the reasons that follow I do not accept that the Authority fell into jurisdictional error, or that the primary judge was wrong to reach that conclusion.
16 First, the Authority considered the appellant's claim that he struggled with his memory because of his mental health. In doing so it summarised the content of the ASETTS letter which had been provided by the appellant in support of this claim. Whilst the Authority reported that its author, Ms Tate, believed that the appellant had symptoms of post-traumatic stress disorder in 2013, it correctly noted that there was no evidence of any mental health diagnosis or that he had undergone any mental health treatment. The appellant freely accepts that the letter provided no information as to the qualifications of Ms Tate and that there was no medical diagnosis of the appellant as suffering from any mental illness, including post-traumatic stress disorder.
17 Secondly, the Authority gave consideration to the evidence provided by the appellant and concluded that his version of events had varied considerably during the course of his application process. That included making findings that documents that had been supplied by the appellant to the Authority were not authentic and that versions of particular events described were implausible.
18 Thirdly, the finding of the Authority at [26] that "[i]n the absence of corroborating evidence" it did not accept that the appellant suffered with his memory because of his mental health amounted to no more than a statement that the ASETTS letter offered by the appellant was not in its view adequate to support his claim. In so saying, the Authority was evaluating the strength of the evidence before it which amounted, first, to simple assertion from the appellant that he suffered with his memory due to his mental health and, secondly, a letter from a person who referred to an unsourced third party test (the Harvard Trauma Questionnaire) and did no more than report its result that the appellant "is symptomatic for Post-Traumatic Stress Disorder". The letter did not state the author's qualifications or indicate that the appellant had been diagnosed by a medical professional with any mental illness. The appellant accepts these deficiencies with the letter, but nonetheless contends that the Authority's treatment of it was irrational having regard to the fact that it had accepted that the appellant had in fact been the subject of traumatic events, including being tortured in 1992 (see [5] above). However, I do not accept that there is an inherent illogicality or irrationality in the Authority finding, on the one hand, that the appellant had been the subject of traumatic events and, on the other, not accepting that the appellant struggled with his memory because of his mental health. This is because it is tolerably clear that the Authority did not consider that the materials supported a finding that the appellant had ever received a mental health diagnosis. The finding at [26] that the appellant did not struggle with his memory was open to the Authority on the materials before it.
19 Further, I reject the contention that the Authority impermissibly imported into its reasoning, through the use of the phrase "corroborating evidence", a legal requirement that the appellant satisfy itself to the standard of the balance of probabilities. Rather, I consider that its use of such language was simply used to explain the evaluative process that it was undertaking as an administrative decision-maker. In so doing it did not fail to consider the ASETTS letter, but rather addressed its content and ascribed weight to it in a way which, having regard to the several deficiencies in its contents acknowledged by the appellants, cannot be described as either irrational or illogical.
20 Consequently, I also reject the contention that the decision of the Authority was illogical or irrational because it took into account the inconsistencies to which it referred in coming to its final decision. In my view, the Authority gave consideration to the material before it in accordance with its statutory task. Based on the findings it made, the Authority did not accept that the appellant met the requirements of ss 36(2)(a) and 36(2)(aa) of the Act. In the course of its reasons, it accepted aspects of the appellant's claims, including that he had been beaten, tortured and imprisoned in 1992. However, the Authority also observed that his version of events of what had happened in the time since then had varied considerably during the course of the application process for his visa. The Authority made findings that documents that had been supplied by the appellant to the Authority were not authentic and that versions of particular events described were implausible. It considered and rejected the appellant's claim that he struggled with his memory due to his mental health on the basis that the materials before it were insufficient to support such a claim. For the reasons stated above, I do not consider that in doing so the Authority acted illogically or irrationally. As a consequence, it was also not irrational or illogical for the Authority to reject certain of the claims made by the appellant on the basis of the inconsistencies in the versions of events he had given.
21 I detect no error in the approach of the Authority, nor in the conclusion reached by the primary judge.
