Chagos Islanders v. United Kingdom, ECtHR 4th Section, 11 December 2012 read admissibility decision
The set of injustices which led to these claims is well known – and see my posts here and here. For the uninitiated, in the 1960s, the US wanted Diego Garcia (one of the Chagos Islands) as a major air base. It spoke nicely to the UK, its owners, who consequently evicted and banned all the inhabitants from it and the neighbouring islands. The constitutional arrangements were apparently decorous. A new UK colony was established (the British Indian Ocean Territory or BIOT) with a Commissioner to make laws for the peace, order and good government of the Territory.
The UN was told that the population consisted of migrant workers, their position had been fully protected, and they had been consulted in the process – none of this in fact happened. Those evicted mainly went to Mauritius and the Seychelles. So the peace, order and good government in fact forthcoming from the UK amounted to total depopulation for military objectives.
