I welcome what the noble and learned Lord has said. If it really is not possible to work up such a schedule before Report—for the reasons that he has explained, I do not see why it should be the case—might not the Government find another legislative opportunity to do so? We know that in the autumn we are likely to have to consider a withdrawal agreement implementation Bill. That might provide an opportunity, although it would be better to do it in this Bill.
The second objection that the Government might make is the need to account for unforeseen circumstances. Since Brexit appears to be a process where every stone turned over reveals yet another problem lurking beneath it, there is some validity to this argument. But if, exceptionally, a new area where a framework is required is identified even after the passage of this Bill with the proposed schedule, there is an easy solution that is wholly consistent with the approach to devolution
adopted to date—namely, a power to amend the schedule by Order in Council with the express agreement of Parliament and those devolved legislatures affected. That could be included in the Bill as well.
In reality, if the Government resist this proposal, we would be right to suspect that they have an ulterior motive in wishing to press ahead with such a wide regulation-making power as that encapsulated in the current amendment, although I accept that it is about to be withdrawn. I commend to the Government the idea of putting in the Bill a list of areas agreed with the devolved Administrations—I stress, agreed—where the constraint on devolved competence will apply and ask them to consider bringing forward an amendment that does that at Report stage.
