My Lords, I am grateful for the contributions from Members of the House with regard to this issue. We are extremely grateful for the extensive work done by the Constitution Committee with regard to the Bill, as set out in the report, and for the consideration that members of the committee have given to the provisions of the Bill and some of the difficult issues that arise in transposing EU-based legislation into domestic law, because it represents something of a challenge in a number of respects.
I shall begin by referring to a matter that does not arise out of this group, or did not until the noble Lord, Lord Adonis, raised it, because it may help if I address his point about whether retained EU law is primary or secondary legislation. It is neither in the Bill. There are provisions in paragraph 19 of Schedule 8 with regard to the Human Rights Act, which is a very particular case, where it will be treated as primary legislation. There is the Constitution Committee’s recommendation that it should all be treated as primary legislation. I shall not go into detail at this stage because we will address this later, but I want to reassure the noble Lord about where we are.
That recommendation raises enormous difficulties because there are aspects of EU-derived legislation that, for example, involve the enumeration of the contents of a particular dye or chemical, and the idea that we could amend that only by way of primary legislation raises issues of its own. Nevertheless, it seems to the Government that there is some scope for considering how we can take this forward, and we are open to considering not only the recommendations of the Constitution Committee but of others. For those who have an interest in this issue, I commend for consideration, at least, the recent observations of Professor Paul Craig of St John’s College, Oxford, in a blog on the UK Constitutional Law Association site dated 26 February—only a few days ago—in which, supplementary to an earlier note that he made, he proposes a categorisation of EU-derived legislation. I cannot say that it is one that we entirely agree with, but it is certainly one that we are looking at because there is more than one route to the resolution of this issue. We are looking at that and, for noble Lords who are interested in that point, it may be worth considering.
