My Lords, this is an extremely difficult question which amounts to whether or not the courts of this country have an authority to set aside a decision of the United Nations. We are under a clear obligation to follow a sanction decision imposed by the United Nations. However, I wonder whether the courts of this country, without absolutely challenging the decision of the United Nations, could give force to the Secretary of State’s attempt to change that decision: in other words, a system could be adopted under which the fault that is found with the United Nations procedure is endorsed by our courts in a way which reinforces the attitude of the Secretary of State in seeking to set aside that sanction rather than just going ahead with a decision which seems to fly in the face of our international obligations under the treaty to which my noble friend referred. I would like to believe that it might be possible for our Secretary of State to go to the United Nations in a case of this kind, with support from the courts of this country, to say that, so far as they can see, the decision of the United Nations is incorrect according to the circumstances narrated in a judgment of the courts here. That might be a way of handling this situation.
I understand the position so far as Europe is concerned. I am not sure whether this situation has ever arisen in that context. That can be looked at but I think there is a question about that. A slightly different situation arises for a group bound by treaty—as the European Union is—as against that for single nations, because if we can do it, who else cannot? We do not necessarily think that the rule of law is observed in the same way in every other country in the world but we cannot make a judgment on that point as a justification for this move. I wonder whether something of this sort should not be done.
