Lord Murray of Blidworth (Con)

The noble Lord seeks to justify his intervention but fails to do so. Because of the way the treaty is drafted and the way Article 18 operates, the treaty can come into force only when this legislation is implemented. That is unusual, but it has the effect of not allowing the noble Lord to make the point he tries to make. He argues that my noble friend Lord Callanan cannot make this amendment because it is in some way in breach of the agreement that has already been signed by the Government, but that agreement is not in force. This is a point we have explored in great detail. I am sure the Minister would agree with me on that point. Moving to the other amendments in the group, I entirely support the amendments in the name of my noble friend Lord Lilley. I am very grateful to the reference that he and my noble friend Lord Bellingham made to the points that I made at Second Reading in respect of the non-recognition of the International Tribunal for the Law of the Sea. I would just add one point in furtherance of that. The International Court of Justice also has no power and no jurisdiction to query the dispute over the Chagos. The noble Lord, Lord Hannay, who I am sad to see is not in his place, heavily relies on the evidence of Sir Christopher Greenwood, but he chooses to ignore evidence which does not favour his case. A very powerful exposition of the contrary case was put by Professor Richard Ekins, KC, professor of constitutional law at Oxford. He made it clear that the International Court of Justice’s jurisdiction specifically excludes any dispute with the Government of any other country which is or has been a member of the Commonwealth. Mauritius’s acceptance of the ICJ’s jurisdiction also excludes disputes with the Government of any other country which is a member of the British Commonwealth of nations. If there had been any basis upon which Mauritius could have sought a binding ICJ judgment against the UK, it would have already done so. The fact is that no such basis exists or has ever existed, which is why Mauritius was forced to use the advisory opinion route to obtain its non-binding advisory opinion. Its bargaining position would have been far stronger if it had had a binding ruling against the UK, but the fact is that it has chosen to negotiate without seeking such a ruling, because it obviously knows that there is no way in which it can obtain such a binding ruling. For those reasons, I strongly support the lock that is present in my noble friend Lord Lilley’s amendment. It would mean that only if there is a binding ruling should this treaty come into force, and therefore the Chagos Islands should remain in British possession and this act of strategic self-harm should be avoided.
