Abstract

This article explores two questions. First, in adjudicating claims under the Human Rights Act 1998 (HRA), should the court defer to the executive or legislature on the ground that the latter two institutions possess superior expertise or information-gathering powers, when such expertise or powers fail to generate persuasive first-order reasons for the court? This article argues that rationality requires courts to defer on these second-order grounds of institutional capacity in situations of judicial uncertainty. Secondly, this article examines an underexplored question in the current literature: when is it justified for courts to consider the government as possessing second-order grounds of institutional capacity that warrant deference? It is argued that rational, impartial and open adjudication in the post-HRA era requires the government to prove its claims of superior institutional capacity, and courts to openly scrutinise such claims by considering a number of factors, including, crucially, the government institution's track record of expertise and credibility.

The kind of situation described here should be distinguished from two other circumstances: (1) where information is hidden from the litigant but not the court, as in what happens when the closed material procedure is used; and (2) where the government conceals information under public interest immunity and does not seek to rely on such information in the trial. These two situations are not the subject of this article's concern.

63. It may be objected that the analogy with expert opinion is flawed. In situations of competing expert testimony, the judge is choosing between the evidence of two experts, whereas in public law cases the judge is choosing between the views of an expert government body and that of a non-expert litigant. In the former situation, it is justified for the judge to reject one expert view as he can choose to rely on another expert view. In contrast, in public law cases, if the judge rejects the government's expert view, he would have to rely on the litigant's non-expert view. In the latter situation, it would hardly be justified for the court to reject the government's expert view unless there are strong grounds for doing so. My reply is that the analogy is applicable in the situation under discussion in which the government and the litigant's first-order arguments are equally strong, or the court is uncertain which side's arguments are stronger. These are situations where the government is unable to demonstrate its relative expertise through first-order reasons. My argument is precisely that in these situations courts ought not automatically to assume that the public body possesses relative expertise, and may only defer if the government can prove that this is the case.
