Of course, “case-by-case basis” suggests lots of work for lawyers and a lot of legal uncertainty. I am grateful to the Minister and all those who spoke in the debate. There was, I think, widespread agreement in the debate—apart from the Minister—and from expert commentators that a legal status does need to be conferred in the Bill on retained EU law. How one confers the legal status is much more difficult than what legal status one confers. I would say that there is more one way to skin a cat—but that may upset those who spoke in the previous debate.
I am grateful to the noble and learned Lords, Lord Mackay of Clashfern and Lord Goldsmith, for supporting the approach recommended by your Lordships’ Constitution Committee. But I agree with the noble and learned Lord, Lord Brown of Eaton-under-Heywood, that there is also great force in the suggestion made by Professor Paul Craig that the Bill should confer a status of either primary or secondary legislation, dependent on the category of EU law from which the retained EU law derives. I say to the noble Lord, Lord Adonis, who asked about this, that Professor Craig is not advocating a process of allocation on a case-by-case basis; he is advocating that legal status should depend on the article of the EU treaty from which the retained EU law derives—a much more objective approach.
