R (Bancoult) v Secretary of State for Foreign and Commonwealth Affairs (No 2) was a case of the House of Lords concerning the removal of the Chagos Islanders and the exercise of the Royal Prerogative. The Chagos Islands, acquired by the United Kingdom in 1814, were reorganised as the British Indian Ocean Territory (BIOT) in 1965 for the purpose of removing its inhabitants. Under a 1971 Order in Council, the Chagossians were forcibly removed, and the central island of Diego Garcia leased to the United States for use as a military outpost. In 2000, Olivier Bancoult brought a judicial review claim against the Secretary of State for Foreign and Commonwealth Affairs for the initial ordinance which led to the Chagossian removal. Bancoult sought a writ of certiorari on the grounds that the ordinance was ultra vires ("beyond power" - that is, that the ordinance had been made without legal authority), a claim upheld by both the Divisional Court and the Court of Appeal. In response, Robin Cook, the Foreign Secretary, repealed the 1971 Order in Council and announced he would not appeal against the decision, allowing the Chagossians to return home.
