The issue around placing a sunset clause on this provision is that, in a way, it creates an artificial cliff edge. The sole purpose of clause 11 is to ensure that the UK statute book is complete on exit day. We want to ensure that we work towards common frameworks, and that we can ensure that, when we have that statute book prepared for exit day, we have common frameworks and non-common frameworks in place. Having a sunset clause creates an artificial cliff edge to work towards that date, whereas we might want to create some of those frameworks before that date, and there might need to be some corrections to the withdrawal agreement and the EU withdrawal agreement Bill that has been announced, and some deficiencies that need to be corrected. Having a sunset clause is therefore unhelpful for the purposes of this clause in itself.
Returning to the issue of the policy areas where EU law intersects with devolved competence, as I have said, common frameworks will not always be required, or can be achieved through non-legislative means like concordats, and in such cases clause 11 provides a mechanism to release decision-making powers from the temporary competence arrangement through the Order in Council procedure, giving new powers to the devolved Administrations.
