"The objection to judicial interference in politics is that it undermines the democratic legitimacy of public decision making. The problem that we have here is that the government itself has sought to undermine the democratic legitimacy of public decision making by dispensing with a central feature of our constitution, namely that ministers are answerable to parliament. What the Supreme Court has done is to invent a brand new rule, that is undoubtedly controversial, a brand new constitutional rule, the effect of which is to reinstate parliament at the heart of the decision-making process. And that is not undermining democracy at all, nor is it a coup, it is simply replacing what ought to have happened by convention, by law, in circumstances where the government has tried to kick away the conventions."
