Whether judicial review should be limited will be a matter for whichever judge the case is put before. My submission is that this is an inappropriate use. The irony when it comes to judicial review is that most JRs of Jeremy Corbyn would come from the Labour Party itself.
Amendment 7 is not a question of allowing Parliament to decide on Brexit. Parliament asked the people to decide the question; the people decided. Parliament voted to invoke Article 50. This Parliament, in this very Session, voted by overwhelming majorities to leave the EU. Parliament has set the law of the land that we should leave on 31 October. It is not a question of anyone stopping Parliament deciding; Parliament has already decided.
