· The UK High Court has rejected a legal challenge against the UK–Mauritius agreement on the Chagos Archipelago — a key development in one of the longest-running decolonization disputes in the Indian Ocean. · The agreement would see the UK transfer sovereignty of the Chagos Islands to Mauritius while leasing back the strategic Diego Garcia base to the UK and US for 99 years. · Opponents of the deal, including Chagossian claimant Bertrice Pompe, argued that the agreement was reached without proper consultation with the Chagossian community. · However, Justice Mary Stacey ruled that the legal arguments raised had already been considered and rejected in previous English court cases. · In short: the High Court found no new legal basis to reopen the issue. · The decision removes, for now, a potential legal obstacle to the implementation of the UK–Mauritius deal. · The controversy is far from over. Critics in the UK and the US — including former US President Donald Trump — have questioned the agreement and its implications for the strategic Diego Garcia base. · But legally speaking, London’s courts have once again reaffirmed the UK government's authority to proceed with the arrangement. · For Mauritius, this ruling strengthens the path toward restoring sovereignty over the Chagos Archipelago after decades of dispute. · Yet the broader geopolitical and humanitarian debates around Chagos — sovereignty, military strategy, and the rights of displaced Chagossians — are unlikely to disappear anytime soon.
