European Union (Withdrawal) Bill

That is enormously kind of the Minister, particularly since the Solicitor General earlier this afternoon persuaded me that his colleague would answer the question that I raised with him in an intervention. Before we are asked to agree to clause 4 standing part of the Bill, will the Minister kindly explain clause 4(3)? It states that all of clause 4 is subject not only to clause 5 but, more importantly, to schedule 1, which, as the Minister knows, stops the general principles at midnight on exit day. We listened to a lot of debate and argument yesterday about clarity and certainty for the courts. There is no definition of the general principles of EU law. Why is that, and what does the provision mean in clause 4?
