In this post I’d like to add a few thoughts on the recent Court of Appeal judgment in Serdar Mohammed, that we already covered on the blog last week (here and here). The case is now heading to the UK Supreme Court, and may also eventually end up in the European Court of Human Rights – although Strasbourg will be looking carefully at the Supreme Court’s judgment even if the case doesn’t find its way to it.
First off, I think everything that can be said about the ‘big issue’ of authority to detain in NIAC has already been said; those already committed to either view are not going to be dissuaded by some novel argument. For my part, I only wish to note that after the Court of Appeal’s (unanimous!) judgment it looks increasingly unlikely that the Supreme Court will overturn the finding of the lower courts (although that of course may still happen), especially bearing in mind the rigour and detail of these lower judgments. It is very difficult for any court to essentially make up rules (in reasoning by implication/analogy/structure or whatever) on who precisely can be detained in NIACs, for how long and under what exact process, in the absence of any meaningful legislative guidance. This is not a gap that most judges would feel comfortable in filling, especially when easy analogies to IACs or (much worse, between targeting and detention) break down.
