I am going to make a little more progress, but I will give way to my right hon. Friend in due course.
The crucial point reflected in clause 6 is that the intention is not to fossilise past decisions of the ECJ for forever and a day. The clause provides that our Supreme Court—and, indeed, the High Court of Justiciary in Scotland—will be able to depart from pre-exit case law. In doing so, they will of course apply the same tests as they do when departing from their own case law in the ordinary way.
We have, in my view at least, the finest judiciary in the world. Our courts are fiercely independent of Government, as they have already proved during the Brexit process. The clause will provide them with clarity about how they should interpret retained EU law after exit. As we take back control over our laws, it must be right that the UK Supreme Court, not the European Court of Justice in Luxembourg, has the last word on the laws of the land. It is therefore of paramount importance that the clause stands part of the Bill.
