European Union Bill

I had moved on to dealing with a new point, but I am willing to go back. I am glad that the hon. Gentleman raised that point, because I can now mention a couple of issues in response. First, any law passed in this country will be interpreted by the courts. If they do something that we do not agree with, this House has the power to change it. The danger with including the sovereignty argument in clause 18 is that courts would then have debates about sovereignty, and that would be strange. How would this House then be able to change the law or interpret a court's interpretation of sovereignty?
