My Lords, I support the amendment and declare my interest as being employed by Cambridge University; essentially my day job is teaching European politics. As the noble Baroness, Lady McIntosh, and the noble Lord, Lord Wigley, have pointed out, this amendment fills a gap in the proposed legislation, although I understand that it is probing in nature. At present, Clause 2 talks about saving EU-derived domestic legislation—that part is clear—while Clause 3 looks at incorporating direct EU legislation. However, the gap lies in EU legislation which has been agreed or adopted, and here I disagree with the noble Lord, Lord Pannick.
If the legislation has already been adopted by the European Union it will not then be amended, so the issue is that if the 28, including the United Kingdom,
have already agreed legislation but the UK has not yet transposed it, that is legislation which we would have expected to be in place at the snapshot point of 29 March 2019. If the legislation has not been transposed by then, there is a question of where we are on 30 March 2019. If, as the noble and learned Lord, Lord Brown of Eaton-under-Heywood, said, it is simply a question of adopting things later, that is one thing for a crash-out Brexit, but if there is going to be a transition period and we are supposed to be absolutely at one with the EU 27 on the day we leave, surely that includes legislation that has been adopted but which we have not yet transposed and which we therefore have a duty to transpose.
