The International Court of Justice’s February advisory opinion on the Legal Consequences of the Separation of the Chagos Archipelago from Mauritius in 1965 is a significant development in the long-running controversy caused by the UK’s detachment of the Chagos Archipelago from Mauritius prior to the realization of Mauritian independence – and the forced removal of the resident population of the archipelago.

In this article for Transnational Legal Theory, I analyse the significance of the ICJ’s opinion in the context of the decades of transnational legal process initiated by both Mauritius and by the displaced Chagossians.

In late April, the UK government responded to the ICJ opinion by asserting that ‘we have no doubt about our sovereignty over the Chagos Archipelago‘.
