Your Lordships should appreciate that the devolved Administrations can make law but have been constrained by EU law in the areas of their competencies. If EU law is taken away, we would expect the devolved Administrations to carry on without that constraint. Previously, there had been no constraint on their making law within their competencies from Westminster, only from Brussels. Taking away Brussels suddenly imposes Westminster constraints on the devolved Administrations in areas such as agriculture, which have been devolved to them, but it also means that the devolved Administrations cannot make any changes to the law at all—even when it is, for example, an agricultural matter. It is not simply taking away the constraint of Brussels, but imposing something entirely new. Westminster politics comes into it then; considerations that have not emerged into the arena before suddenly become important. That is why these are matters of principle and deeply difficult to resolve.
I was so pleased to hear the noble Lord, Lord Hennessey, say that this was such a difficult area because I suggested in my Second Reading speech that we should have taken devolution completely out of the Bill. At that point, the Government would have had no problem in getting legislative consent from Scotland and Wales and could have sorted out devolution issues as a completely separate matter. Now, your Lordships are listening—in the context of the EU (Withdrawal) Bill—to a very difficult issue.
