May I gently say to my hon. Friend that although this is fascinating, we are actually talking about retained EU law which will not be subject to the jurisdiction of the Court of Justice of the European Union? I do have criticisms of the CJEU and the way it has operated at times, and I have had the pleasure, or misfortune, of appearing before it. Its teleological principles and its purposive interpretation of law have often been challenging in our national setting, although it is not a pariah court and by international standards it is a pretty good tribunal. So I stand by the points I made on that occasion, but they in no way diminish or undermine anything that I have said here this afternoon.
