As I have said, this is a power of publication. It is important not only that we formally delete it, as my right hon. and learned Friend says, but that we provide that it does not end up in the wrong place and thereby mislead the reader or those who want to find an authoritative source for retained EU law. Another example would be EU regulations that have entered into force but are only partially applicable here immediately before exit day. One example is regulation 2016/2031 on protective measures against pests of plants, which has entered into force. One provision applies now, but the rest will apply in the EU only after exit day. To answer him directly, that is why the power exists.
I shall move on to paragraphs 3 and 4. Paragraph 3, as the keenest Members will have observed, is based on section 3(1) of the 1972 Act, which provides that
“any question as to the meaning or effect of any of the Treaties, or as to the validity, meaning or effect of any EU instrument, shall be treated as a question of law”,
and, of course, when something is a question of law, a court can determine the meaning of that law for its own purposes. Foreign law is normally a question of fact to be pleaded and then proved, often by recourse to expert evidence. Quite rightly, however, we want to allow a question of EU law to continue to be treated as a question of law after exit day, for certain purposes, such as when it is necessary to decide the question of EU law for the purposes of interpreting retained EU law in legal proceedings here.
