This article discusses the United Kingdom Supreme Court judgment in Zubaydah v Foreign, Commonwealth and Development Office, which addressed the law governing the tort liability of the United Kingdom Government for its alleged complicity in the claimant's arbitrary detention and torture overseas by the Central Intelligence Agency. In holding that English law applied, the Court departed from previous case law by giving decisive weight to public law factors in its choice-of-law reasoning. This decision arguably heralds a greater role for English law in relation to tort claims brought by overseas victims of allegedly wrongful exercises of British executive authority as a mechanism for achieving executive accountability, controlling abuse of power, ensuring the rule of law and providing victims access to remedy.
