Lord Purvis of Tweed (LD)

Part of the noble Lord’s lack of involvement was in not raising his objections in Parliament at the time. If those negotiations were entered into to resolve the legal considerations then the Statement in 2022 undermines his quite novel argument now. It is the case that the previous Government entered into those negotiations. I believe that they entered into them in good faith and they knew what the conclusions would be. The argument of the noble Lord, Lord Bellingham, is of course correct with regard to the 2017 declaration by the United Kingdom Government that they would be able to choose not to adhere to any rulings by the ICJ on the basis of a Commonwealth country, if that dispute started after 1987. It is a moot point whether this dispute started before then; there remain many arguments that it had. However, even if he is right, I am certain that the former Attorney-General—one of potentially three in 2022—would have advised the previous Administration that, regardless of that 2017 UK declaration, the ICJ would, as under its statute, refer to the General Assembly, because that is its purpose, and that there would be a resolution at the General Assembly. That was the entire point of the ICJ considering it, because it was referred to the ICJ by the General Assembly. I understand the noble Lord’s argument, but we would not be in a different place now even if his argument was very robust. On the argument of the noble Lord, Lord Callanan, and our little to and fro on the treaty, we have been told on many occasions by the noble Lord, Lord Callanan, and his colleagues in the previous Administration that treaty-making is a prerogative power. We do not have that short a memory in this House; we recall the Rwanda Bill and the Rwanda treaty. I recall the noble Lord, Lord Murray of Blidworth, telling us that it was not our role to interfere in the prerogative power of Governments making, implementing or changing treaties. I quote: “My Lords, we are not aware of any precedent for Parliament mandating the Government in international negotiations conducted under the royal prerogative. The Government were not prepared to accept such a significant … shift”.—[Official Report, 24/7/18; col. 1598.] That is ultimately what the amendment from the noble Lord, Lord Callanan, puts forward. That quote from Hansard is from the noble Lord, Lord Callanan. He was insistent that it was not Parliament’s role to interfere or mandate a Government in the negotiation of treaties under the royal prerogative. He was either wrong then and right now, or he was right then and wrong now. I am sure he will be able to say which when he sums up the debate.
