Verification of documents
(1) The decision of the Immigration Appeal Tribunal in Tanveer Ahmed [2002] UKIAT 00439 remains good law as regards the correct approach to documents adduced in immigration appeals. The overarching question for the judicial fact-finder will be whether the document in question can be regarded as reliable. An obligation on the respondent to take steps to verify the authenticity of the document relied on by an appellant will arise only exceptionally (in the sense of rarely). This will be where the document is central to the claim; can easily be authenticated; and where (as in Singh v Belgium (Application No. 33210/11)), authentication is unlikely to leave any ‘live’ issue as to the reliability of its contents. It is for the tribunal to decide, in all the circumstances of the case, whether the obligation arises. If the respondent does not fulfil the obligation, the respondent cannot challenge the authenticity of the document in the proceedings; but that does not necessarily mean the respondent cannot question the reliability of what the document says. In all cases, it remains the task of the judicial fact-finder to assess the document’s relevance to the claim in the light of, and by reference to, the rest of the evidence.
The Mibanga duty
(2) Credibility is not necessarily an essential component of a successful claim to be in need of international protection. Where credibility has a role to play, its relevance to the overall outcome will vary, depending on the nature of the case. What that relevance is to a particular claim needs to be established with some care by the judicial fact-finder. It is only once this is done that the practical application of the ‘Mibanga duty’ to consider credibility ‘in the round’ can be understood (Francois Mibanga v Secretary of State for the Home Department [2005] EWCA Civ 367). The significance of a piece of evidence that emanates from a third party source may well depend upon what is at stake in terms of the individual’s credibility.
(3) What the case law reveals is that the judicial fact-finder has a duty to make his or her decision by reference to all the relevant evidence and needs to show in their decision that they have done so. The actual way in which the fact-finder goes about this task is a matter for them. As has been pointed out, one has to start somewhere. At the end of the day, what matters is whether the decision contains legally adequate reasons for the outcome. The greater the apparent cogency and relevance of a particular piece of evidence, the greater is the need for the judicial fact-finder to show that they have had due regard to that evidence; and, if the fact-finder’s overall conclusion is contrary to the apparent thrust of that evidence, the greater is the need to explain why that evidence has not brought about a different outcome.
