R v Secretary of State for Foreign and Commonwealth Affairs, ex p Bancoult (No 1)

R v Secretary of State for Foreign and Commonwealth Affairs, ex p Bancoult (No 1) [2000] EWHC Admin 413 was a 2000 legal case in which Olivier Bancoult sought a judicial review of the ordinance which allowed the Chaggosian people to be forcibly removed from their homeland. A divisional court ruled that the ordinance that allowed the removal was "ultra vires" as the power to legislate for "peace, order and good governance" of the territory did not include a power to expel the inhabitants.

The ordinance was replaced by an Order in Council, and in R v Secretary of State for Foreign and Commonwealth Affairs, ex p Bancoult (No 2) this was upheld as legal by the House of Lords in a 3-2 judgment.
