evidence: In addressing the second question, having established that the process of decolonization of Mauritius was not lawfully completed in 1968, the Court examined the consequences, under international law, arising from the United Kingdom’s continued administration of the Chagos Archipelago. In particular, it was of the opinion that the United Kingdom’s continued administration of the Chagos Archipelago "constitutes a wrongful act entailing the international responsibility of that State", that the United Kingdom "has an obligation to bring to an end its administration of the Chagos Archipelago as rapidly as possible, and that all Member States must co-operate with the United Nations to complete the decolonization of Mauritius". Since respect for the right to self-determination is an obligation erga omnes, all States have a legal interest in protecting that right, the Court found. It considered that, while it is for the General Assembly to pronounce on the modalities required to ensure the completion of the decolonization of Mauritius, all Member States must co‑operate with the United Nations to put those modalities into effect.
