European Union (Withdrawal) Bill

Is not one of the central problems of the Bill that the legislation is so broadly drafted that there is no effective means for the courts to exercise judicial review, and that the reason we need these principles in it is to enable the court to get a grasp, which would be much better than if there is nothing there at all? Otherwise, we would have to live with a hotch-potch of precedents, which the Secretary of State referred to in the Select Committee.
