In 2004, following the decision of the British government to promulgate the British Indian Ocean Territory Order, which prohibited the Chagossians from remaining on the islands without express authorisation, Mauritius contemplated recourse to the International Court of Justice to finally and conclusively settle the dispute. However, article 36 of the International Court of Justice Statute provides that it is the option of the state whether it wishes to subject itself to the court's jurisdiction. Where the state chooses to be so bound, it may also restrict or limit the jurisdiction of the court in a number of ways. The UK's clause deposited at the court excluded, amongst other things, the jurisdiction of the court with regard "to any disputes with the government of any country which is a member of the Commonwealth with regard to situations or facts existing before 1 January 1969". The temporal limitation of 1 January 1969 was inserted to exclude all disputes arising during decolonisation. The effect of the British exclusionary clause would thus have prevented Mauritius from resorting to the court on the Chagos dispute because it is a member of the Commonwealth. When Mauritius threatened to leave the Commonwealth, the United Kingdom quickly amended its exclusion clause to exclude any disputes between itself, Commonwealth States and ''former Commonwealth States'', thereby quashing any Mauritian hopes to ever have recourse to the contentious jurisdiction of the court, even if it left.
