Well actually, oddly enough, I intend, as previously in Committee, to attend to one of the amendments-in fact, two-rather than to the general question of whether it is a good idea to leave the EU. I want in particular to speak about amendment 400-a Government amendment now-and amendment 381, the original Government amendment to which it relates, in a sort of package. There has been a certain amount of confusion in discussion of the amendments in public-although not, I hope, in the House-so I first want to make it quite clear what they do and can do and what they do not and cannot. The issue has often been reported as if it relates to the question of when we withdraw from the EU, which is very interesting but nothing to do with the amendments. Neither is it anything to do with the Bill, because withdrawal from the EU, as all hon. Members present know, is governed by the article 50 process, not by an Act of Parliament. If we could wave a wand and decide how we do these things through an Act of Parliament, how much easier that would be; but there is an article 50 process that is part of international law, to which we subscribe, and that is what will determine when we leave the EU. What do the amendments do? They govern when clause 1 will become operative. Clause 1 repeals the European Communities Act 1972 and Government amendment 381 sets a date for that. That leads to a question. If the UK Government and the EU, according to the processes laid out by article 50 and by the remainder of the constitutional arrangements of the EU, come to some kind of agreement at a certain point, it would make sense to have a little more time than is allowed under the first clause of the article 50 process. Under the third clause of the article 50 process, we would have an odd situation, because there would be a slight delay in the timing of our withdrawal, where we would still, under amendment 381, be locked into abolishing the 1972 Act on a certain date, namely by 11 pm on 29 March 2019. There would therefore be an odd conflict of laws that obviously could not be allowed to persist. Incidentally, there would then be perfectly obvious remedy: under Government amendment 400 there would be a need for emergency primary legislation to change the date. That is, of course, perfectly possible and I have no doubt the House and the other place would agree to such a measure, but it is a laborious process and it might jam up the works at just the moment when it is very important for the Government to have the flexibility to make an agreement of that sort. So, very modestly, all Government amendment 400 does is to provide for the ability of Parliament to adjust the date under those circumstances for the repeal of the European Communities Act to match the article 50 process.
