The Sovereign Base Areas (SBA) are two parts on the island of Cyprus, with a combined territory of 99 square miles, over which the UK exercises sovereignty. They were created by the Treaty of Establishment 1960, which is also the international agreement that granted the Republic of Cyprus its independence. The article maps out the implications of the Chagos Archipelago Advisory Opinion for the SBA. It argues that the process through which they were created entirely disregarded the wishes of the Cypriot people and was, therefore, not in accordance with the right to self-determination.
