I am not sure I agree with the term “red lines”; it is not one that I am inclined to use. I am never quite sure what they are. Our position is that during an implementation period, if and when finally agreed, we will accept that there is a role for the European Court of Justice. Indeed, it is outlined in the EU’s own proposals for the agreement at Articles 82 through to 85. As the noble and learned Lord indicated, that is not yet the subject of final confirmation between the two parties but it is what is anticipated.
On a related point, during that period, I agree with the noble and learned Lord, Lord Hope, that as we cease to be a member state we will cease to have the right to have a judge in the Court of Justice of the European Union. That must follow. However, we will have the right to make interventions in cases that pertain to the United Kingdom.
