Diego Garcia Military Base and British Indian Ocean Territory Bill

Contribution

In response to the desire of the noble Lord, Lord Callanan, that we are clearer in the Bill about what it does, I have read it a couple of times and honestly do not think that it could not be any clearer. It is a Bill to enact an agreement between the United Kingdom and the Republic of Mauritius concerning the Chagos Archipelago. I think that is sufficient, and if he does not, I am not sure what he is getting at. The Government rejects Amendment 33 on the basis that the provision in question is not redundant. It is needed to ensure the secure and effective operation of the base. It ensures clarity on which law will apply through the jurisdiction that the UK will exercise under the treaty. Legal continuity and certainty for operations on the base once the British Indian Ocean Territory is dissolved is far from unnecessary. Let me explain why we have Clause 3. This clause saves the law of BIOT, and law which relates to BIOT, as the law of Diego Garcia and law which relates to Diego Garcia. This has been done as the default, to ensure the continued effective running of the base on Diego Garcia and to make sure that there is no legal gap. Detailed work is being carried out to establish where technical amendments may be needed to this preserved law to reflect the new status of Diego Garcia. Diego Garcia is defined in Clause 3 as the whole area that the UK can exercise jurisdiction over, as covered in the treaty. This includes the island of Diego Garcia and the 12 nautical miles surrounding it. Preserving the existing prerogative power to legislate for Diego Garcia means that we can continue to operate the base and its legal architecture in much the same way that we do today, and it gives the maximum flexibility for the future. Amendment 51, tabled by the noble Lord, Lord Callanan, seems to be based on a misapprehension. As I mentioned in my response to the amendments related to Clause 3, His Majesty has a prerogative power to legislate for BIOT at present and Clause 3 preserves this power. It does not allow him to make laws for other parts of the realm about BIOT or Diego Garcia. If the noble Lord reads that clause of the Bill again, he will see that I am right about that. The statutory power in Clause 5 is necessary to enable amendments to Acts and statutory instruments which form part of the law of Diego Garcia and amendments to legislation which forms part of the law of other jurisdictions—the UK Crown dependencies and the other OTs. These other jurisdictions have laws which refer to BIOT or treat it as one of the overseas territories. Amendments to those laws may be necessary to reflect the new status of Diego Garcia. I see that the noble Lord, Lord Lansley—as is becoming classic in his contributions on these occasions—has read the report from the DPRRC. His Amendments 51A, 51B and 51C appear to seek to implement its recommendations. Amendment 51BA, tabled by the noble Lord, Lord Lilley, appears to be less consistent with the recommendations—I think he has recognised that in his remarks—in that it would impose the affirmative procedure in respect not just of Orders in Council, which amend primary legislation, but of those which amend secondary legislation. Without showing too much leg so late at night, we are still considering these suggestions and we will return to them on Report. With that, I hope noble Lords will not press their amendments.
