Lord Morrow (DUP)

My Lords, Amendment 20J in my name proposes that Clauses 2 to 4 do not come into force until the Secretary of State has produced a report setting out the reasons for rejecting the alternative legal remedies to those set out in the Mauritius treaty for resolving challenges to the United Kingdom’s sovereignty of the Chagos Archipelago. At the heart of the Government’s justification for proceeding with the Bill to bring the Mauritius treaty into force is the non-binding judgment of the International Court of Justice from 2019. The Government have, I think, acknowledged that it is not binding but have sought to ensure that, if it is ignored, binding judgments will quickly arise and other countries upon which we depend to run the base would then refuse to help. The Government have not clearly explained what these feared judgments are and why they would be binding. I invite the Minister to do so in detail and to tell the Committee which countries we depend on to run the islands, which we think would then refuse key services and what those services are. However, in this amendment, I want to probe a different approach. The Government tell us that this is a critical Bill because its passage will facilitate the coming into force of the Mauritius treaty. The treaty is vital because the United States has told the UK Government that it is unhappy about having a major US base on Diego Garcia when the sovereignty of Garcia is contested. Furthermore, it has paused investment on Diego Garcia, which will not recommence until the legal standing of the Chagos Islands has been resolved. It is crucial that this matter is resolved, because the security—not just of the United States but of the United Kingdom and the West—depends on full US investment in Diego Garcia. In this context, the reason why the Bill and the treaty, which will come into force if it becomes an Act of Parliament, are vital is because they set out the only route to legal certainty for the standing of the US military base. However, this solution does not provide the only way forward to secure legal certainty, and there are alternative ways forward that would better secure legal certainty than the Bill and the treaty. It is the purpose of my amendment to ask the Government to consider these alternatives. The problem with the Government’s approach in claiming that the treaty constitutes the only legal way forward is that it is the product of a non-binding legal judgment that was a response to the disagreement between two parties—the Republic of Mauritius and the United Kingdom. The Chagossians were not a party to the case because at that time they did not have international personality. Had they been a party then, the judgment would have dealt with a wider range of issues and considered a wider range of ways forward.
