In a historic decision, the UN General Assembly has voted, by 94 to 15, to ask the International Court of Justice for an advisory opinion on the Chagos Archipelago. The Chagos Archipelago was excised from the territory of Mauritius by the UK in 1965, including the expulsion of its residents, before Mauritius gained its independence in 1968. It is now the site of a controversial US military base on the island of Diego Garcia. The ICJ will be asked to consider whether the process of decolonisation has been completed, and the legal consequences of the UK’s continued administration of the Archipelago. Philippe Sands QC and Alison Macdonald QC are advising Mauritius.
