May I at least give the answer before my right hon. and learned Friend jumps in?
That is why the agility that clause 9 gives us is important. I do not mean to correct my hon. Friend the Member for Eddisbury (Antoinette Sandbach) in a lawyerly way, but it is not quite right to say that clause 9 can legislate for anything in the context of departing the EU. It relates only to the withdrawal agreement, and I think she said it related to withdrawing from the EU.
Another illustration of what clause 9 could be used for is the spelling out of the technical detail of how ongoing UK cases at the European Court of Justice should be handled, and how the UK courts should treat resulting judgments. Some of that might be done under
this Bill, and some under the withdrawal agreement, but we will need to clarify things such as the types of cases that would be in scope and the precise procedural points in terms of whether a case could be considered to be pending, among others. Without that clarification, how such cases should be treated might not be clear. We would run the risk of legal uncertainty, as well as uncertainty for the individuals involved in those cases.
I do not want to make too much of that before my right hon. and learned Friend the Member for Beaconsfield jumps in. He is quite right—he has made this point before, and he may want to hear me out before I take his intervention—that, in 2016, there were 23 preliminary references from UK courts and just one infraction case against the UK. So we do not expect this issue to affect large numbers. None the less, for those affected, it is still important to get this right.
