3.2 Did the Tribunal err in giving the appellant's supporting documents no weight?
27 The appellant also submitted that the Tribunal erred in the way in which it dealt with his supporting documents. In the further written submission filed after the hearing, the appellant submitted that:
(1) despite its credibility concerns, the Tribunal was obliged to consider the documents provided by the appellant in support of his claims;
(2) the fact that the aspects of his claims were found to be not credible does not allow the Tribunal to give his documentary evidence no weight;
(3) nor is the existence of document fraud in Sri Lanka a valid reason for disregarding the documents on which the appellant relied;
(4) the Tribunal ought to have made clear findings of fact with regard to the nature of the appellant's documents after considering the documents rather than giving them no weight; and
(5) the Tribunal ought to have made a finding as to whether the documents were genuine.
28 By way of example, the appellant pointed to the Tribunal's rejection of his claim that he joined the UNP in 2008 and became a member in 2009 (at [67]), and submitted that the "Tribunal surely could not have made that finding without properly considering and assessing if the documents I provided were genuine or not. I provided amongst other documents a …UNP membership card."
29 The Tribunal's reasoning relevantly begins with its consideration of whether the appellant was a credible witness based upon his evidence at the hearing and in response to the notice given under s 424AA. In this regard, the Tribunal identified various inconsistencies and deficiencies in the appellant's evidence with respect to his claims. This included his lack of knowledge of information of which the Tribunal considered a person with his level of claimed involvement would know and deficiencies in his explanations, each of which were said to add to the Tribunal's finding that the appellant is not credible as to his claims (at [49]-[60]). The Tribunal concluded at [61] with respect to his credibility that:
For all the above reasons, considered cumulatively the Tribunal does not find the applicant to be a credible, truthful and reliable witness as to these claims. The Tribunal is of the view that the applicant has fabricated these claims and concocted evidence to achieve an immigration outcome. On the basis of the above cumulative credibility concerns the Tribunal therefore does not accept that the applicant is a credible witness as to these claims and cannot be satisfied on the evidence before it that the applicant is a truthful witness as to his claims as to being targeted because of his active political involvement in the UNP, being involved in politics generally or because of his family involvement in the UNP.
30 In so finding, the Tribunal took into account the possibility of discrepancies for example because of genuine lapses of memory (at [62]). The Tribunal also took into account that some of the information provided by the appellant had been consistent over time. However, the Tribunal did not consider that the appellant's consistent evidence on those matters outweighed its significant credibility concerns given that those matters were relatively easy matters to recall (at [63]).
31 Having so found, the Tribunal at [64]-[65] turned to consider the documentary evidence which the appellant submitted to support or corroborate his claims:
The Tribunal has considered the documentation he has submitted to support his claims. Firstly as raised with the applicant the letter from Jam Cyril refers to him being involved in the May Day Rally [at a particular location], which the applicant has not provided any information he was involved, which the Tribunal may expect if true. Therefore on the basis of this, his lack of lack of credibility as to these claims and information on the prevalence of document fraud in Sri Lanka I place no weight on this letter as evidence of the difficulties faced by the applicant as outlined in this letter and activities he undertook in Sri Lanka to campaign or support for the UNP or that he was involved in a May Day rally [at the relevant location].
Similarly as raised with the applicant on the basis of his lack of credibility as to these claims and prevalence of document fraud in Sri Lanka I place no weight on the following letters to support the applicant's claims of active involvement in the UNP, membership of the UNP, campaigning for the UNP and its candidates, threats or difficulties as a result or that he fled Sri Lanka for these reasons…
32 The Tribunal then listed the letters from third parties and other documents on which the appellant relied.
33 In essence, therefore, the Tribunal gave those documents no weight given the country evidence as to the prevalence of document fraud in Sri Lanka and its findings as to the lack of any credibility in the appellant's evidence. I do not consider that the Tribunal fell into jurisdictional error in so deciding.
34 First, it was open for the Tribunal to have regard to country evidence in assessing the appellant's claims and to give that evidence such weight as the Tribunal considered appropriate including so as to prefer that evidence over the appellant's documentary evidence. As, for example, the Full Court explained in NAHI v Minister for Immigration and Multicultural and Indigenous Affairs [2004] FCAFC 10 at [11]:
By s 420(2)(a) of the Migration Act, the Tribunal is not bound by the rules of evidence. By s 424(1), in conducting a review, the Tribunal may get any information that it considers relevant. There can be no objection in principle to the Tribunal relying on 'country information'. The weight that it gives to such information is a matter for the Tribunal itself, as part of its fact-finding function. Such information as the Tribunal obtains for itself is not restricted to 'guidance', as the appellants submitted. It may be used to assess the credibility of a claim of a well-founded fear of persecution...
35 Secondly, it was open to the Tribunal to have regard to its findings as to the appellant's credibility in deciding whether, given the country information about fraudulent documents, it would accept these particular documents as credible. In this regard, the Tribunal was entitled to make an assessment of the appellant's credit before considering the corroborative evidence. There is nothing irrational about the Tribunal rejecting a document by giving it no weight in circumstances where, as here, it has found that the witness is not credible and there is no evidence of the document's authenticity other than that given by that witness: Minister for Immigration and Citizenship v SZNSP [2010] FCAFC 50; (2010) 184 FCR 485 at 491-492 [36]-[37] (North and Lander JJ), 493 [50] (Katzmann J).
36 I reached a similar view in BAX15 v Minister for Immigration and Border Protection [2016] FCA 491 at [30]- [32] in accepting that there was a logical and intelligible justification given for the Tribunal's decision in that case not to afford a letter on which the appellant relied any weight. In particular at [30]-[32] of my reasons, I held that:
…in my view, it was open to the Tribunal to attach no weight to the letter. It is apparent from the Tribunal's reasoning at [177] that its finding that it could give the letter no weight took into account not only the content of the letter and various deficiencies which cast doubt upon its genuineness, but also the Tribunal's findings that the appellant was not affiliated with the BNP due to inconsistencies in his evidence and country information. I accept in this regard the Minister's submission that the Tribunal's approach accords with the "poisoned well approach" articulated by McHugh and Gummow JJ in Minister for Immigration and Multicultural Affairs; Ex Parte Applicant S20/2002 (2003) 198 ALR 59 at [49], namely:
… [I]t is not unknown for a party's credibility to have been so weakened in cross-examination that the tribunal of fact may well treat what is proffered as corroborative evidence as of no weight because the well has been poisoned beyond redemption.
The same may equally be said where the party's credibility has been so weakened by questioning, as here, in an inquisitorial hearing by an administrative tribunal.
37 For these reasons, the appellant's challenge to the Tribunal's findings on the appellant's documentary evidence must be dismissed.
