My Lords, I will not add to the exposition of the amendment and the reasons for tabling it, which have been so clearly set out by the noble Lord, Lord Pannick. The committee felt that we ought to see whether we could get a more secure place for retained European law in the hierarchy of law as it would be viewed by the courts in this country. There will probably be difficulties in this area and we are probably persuaded that they cannot be resolved by the kind of declaratory amendment that we have tabled on this occasion.
There are further difficulties which the Minister might refer to, which have been pointed out by Professor Alison Young, who was referred to earlier. For example, constitutional statutes are not subject to the doctrine of implied repeal in the same way as other legislation. What will be the position if an item of retained European law is considered to be constitutional in character and appears to be in conflict with subsequent legislation passed post exit day, when the supremacy principle has fallen away and this has to be resolved?
In passing an earlier amendment which removed a discretionary power from Ministers to, in effect, decide whether matters could be put before the courts, we wanted to assert that, wherever possible, we should protect the courts and the legal system from having to be the subject of individual ad hoc ministerial decisions in particular cases. That was part of the motivation for what the committee sought to do in this case. But clearly it cannot be solved in the way that we first suggested.
