The quashing of primary legislation: mystifying or mundane? – Administrative Court Blog
‘This post examines a section of the judgment in R (Mandarin and others) v BIOT Commissioner (the appeal against which is listed for 15-17 July 2026) and traces the origins of its outcome as part of a long-running political dispute between the UK Government on the one hand and the Chagossian people on the other. The primary focus is on Lewis CJ’s reasoning in [150]-[179] of the judgment. The post does not comment on the political dispute or evaluate its various positions. Instead, I ask two constitutionally focused questions. First, how was primary legislation quashed in a constitutional tradition historically and categorically allergic to the idea? Second, are Acts of the UK Parliament next?’
