The Chagos archipelago in the Indian Ocean has garnered media attention recently after the UK failed to abide by a UN deadline to return the islands to Mauritius. The US has landed in the middle of the dispute as a 1965 agreement with the UK has allowed the US to establish a military base on one of the islands, Diego Garcia, which has since become instrumental in US missions in the Asia-Pacific and the Middle East. 

In February 2019, an Advisory Opinion of the International Court of Justice (ICJ) found that the Chagos archipelago was unlawfully dismembered from Mauritius, in violation of the right to self-determination and that the United Kingdom is under an obligation to end its administration of the Chagos archipelago ‘as rapidly as possible’. The UN General Assembly subsequently voted overwhelmingly in favour of the UK leaving the islands by the end of November 2019 and the right of the former residents who were removed by the UK to return. The UK does not accept the ICJ and UN rulings and argues that the islands are needed to protect Britain from security threats while Mauritius has made clear the base can remain.

Professor Philippe Sands QC, professor of law at University College London and lead counsel for Mauritius on the ICJ case on Legal Consequences of the Separation of the Chagos archipelago from Mauritius in 1965, will be joining Ambassador Richard Burt, US chief negotiator in the Strategic Arms Reduction Talks with the former Soviet Union for a discussion on the fate of the archipelago including the future of the military base and the right of return of former residents.

The decision by the International Court of Justice (ICJ) that Myanmar should take all measures available to prevent acts of genocide against the persecuted Rohingya minority is truly ground-breaking. The case shows how small states can play an important role in upholding international law and holding other states accountable. 

The Gambia, acting with the support of the Organization of Islamic Cooperation, skilfully used Article IX of the Genocide Convention, which allows for a state party to the convention to pursue cases against another state party where it is felt there has been a dispute regarding the ‘interpretation, application or fulfilment’ of the convention.

Seventeen states have entered reservations against this specific provision but Myanmar is not one of them. It was on this basis that The Gambia was able to take its case to the ICJ. This exciting development expands the possibilities of international accountability at the state-to-state level.

But it should be noted that the current ruling is focused on provisional measures – the central case could still take years to conclude. There is still a long road ahead on the court determining whether the Myanmar authorities committed acts of genocide.

And, while the decision was unanimous and binding, the ICJ cannot enforce its ruling. Myanmar has shown itself resistant to international criticism and there is a real risk they will fail to comply.

One way forward, should Myanmar not respect the ruling, is that the UN Security Council could agree a resolution to compel action. However, it seems unlikely that China would ever vote for such a resolution, given its strong stance on non-intervention and its economic interests in the country.
