I note what the noble Lord says. All I would say in response is that, in the context of a single market such as the European single market, it has been necessary and sometimes highly useful to have the legal mechanism there in order to resolve difficulties that have arisen—as we heard from the noble and learned Lord a moment ago. My amendment is a constructive attempt to ensure that the amendment tabled by the noble and learned Lord, Lord Mackay, is acceptable to the devolved legislatures, which I believe it can be. I believe that it needs to be tweaked, if not by this wording then along these lines.
The core of the argument that the noble and learned Lord is putting forward in his amendment is very important indeed—and I think there is a similar amendment coming forward from the noble Lord, Lord Foulkes. The fact that these amendments are coming forward from different sides of the House is in response to the need to resolve this issue. We cannot have this going on and on in the way that it has. It has gone on for far too long now. There needs to be a resolution that is recognised and accepted by all sides and seen to be even-handed. I believe that there is, as he himself has indicated unofficially, a feeling in both Cardiff and Edinburgh that, if the amendment could be incorporated, along with my proposed addition or something along those lines, it could be seen as breaking the logjam. For that compelling reason, I invite the noble and learned Lord, Lord Mackay, to accept Amendment 318AA, and then for the Committee to accept his amendment.
