My Lords, I pay tribute to the noble Lord, Lord Bew, because he has at least made the effort to present an argument as to why the Bill is not a breach of international law—something that the noble and learned Lord, Lord Stewart, the Advocate-General for Scotland, for whom I have great admiration in other circumstances, expressly declined to do at the end of Second Reading. As I understand it, the argument
from the noble Lord, Lord Bew, is that international law includes the Good Friday agreement, which recognises the need to pay close attention to the views, interests and aspirations of all sections of the community—and here, most relevantly, the views of the unionist community, and in particular the DUP.
That argument deserves an answer so I will attempt briefly to explain why, in my respectful view, it is hopeless as a matter of international law. The reason why the argument is hopeless is that international law states that the doctrine of necessity simply cannot apply where the Government have caused or contributed to the problem that they now perceive and are seeking to address. The noble Lord, Lord Bew, cannot get away from the basic facts that the Government negotiated and signed the protocol. In international law, it is simply elementary that a state cannot sign a specific agreement and then seek to resile from it because it takes the view that it is neither convenient nor in the interests of particular sections of the community. Indeed, the Government signed the protocol—and said they did so—because they took the view that it was the best way of protecting the views of all sections of the community, including the DUP. It therefore follows that, if the Government take the view that this is unacceptable, inconvenient and does not meet the DUP’s aspirations, international law demands that the Government negotiate with the EU and attempt to arrive at another solution. It is as simple as that.
