I beg to differ from the noble Lord. The Committee will also bear in mind that anything the European Council does, or seeks to do, is itself subject to the requirements of the treaties. If it does something which is thought to be outside the treaties, that is justiciable in the courts of this country—we now know very well that they can do that—but also in Brussels and Luxembourg. I do not see a problem with that. I do not see the difficulty that is raised. The Bill is clear that, if we get the answer, “You can have this extension to this date”, the Prime Minister has to act. If the date is different, that is a different consideration, and will have to be considered by the Commons. However, if we were to make an amendment now to deal with something that we are being advised the European Council could not do, we would be defeating the Bill because we would be sending it back to the Commons, which would not be sitting to receive that amendment and deal with it. I therefore respectfully invite the noble Baroness to withdraw her amendment. If she does not do so, certainly we will oppose it.
