Disputes over arbiters
In 2011 the government of Mauritius used the Permanent Court of Arbitration to challenge Sir Christopher Greenwood's role in the arbitration proceedings on the grounds that his role as a UK Foreign and Commonwealth legal adviser could bias him in favour of the United Kingdom's claims to the Chagos Islands. However this was rejected by the Court on the basis that this "neither constituted nor continued an already existing relationship."
