My Lords, the existence of these powers in the Bill has created an apprehension in a lot of people that the Government are proposing to use the powers in some way to undermine something that is valuable to them. It is therefore important—apart altogether from the argument that examines the detail—that we examine this carefully. The noble Lord, Lord Wilson of Dinton—with his background of great success as a civil servant, no doubt contributed to by his early experience as a lawyer—has moved the amendment in a way that has made it extremely clear. It is quite clear to me that necessity is a better test on which to leave these powers than the discretionary test of “appropriate”. It is not absolutely right that discretion is not subject to judicial review, but at least an objective test is certainly more likely to lead to successful judicial review if it is transgressed.
We have to remember the huge task involved in trying to put these two systems together; the European system, which has been here for 45 years, has been working alongside our system and kept separate from
it over all that time. That is by no means an easy task. Indeed, what we already discussed with regard to Clauses 2 and 3 illustrate that. It is difficult and time consuming, and we must ensure that the solutions we suggest to the Government are practical and will enable this to be done in a reasonable time so that the statute book can be right on Brexit day.
I anticipate that the test of necessity will be an easier one to apply for those entrusted with the power than the test of what is appropriate. The latter involves an element of judgment, which is not always easy to exercise; whereas if it is obvious that these two bits do not fit together, it is necessary to do something about it. As the noble Lord, Lord Wilson, said, it is not necessary to circumscribe the solution. The argument that necessity suggests not only that the amendment is required but also what particular amendment is required stretches the matter a little far. So long as it is necessary to do it, that is a sufficient test for our purpose, and then it is for the Minister to do his best to sew these two pieces together.
I am somewhat alarmed at the survey by the noble Lord, Lord Wilson, of the people entitled to use this power, and the Minister may well have something to say about that. However, there is a lot of work to do, and we do not want to overwork the Ministers with necessary adjustments when they ought to be doing something else. There is certainly plenty to do between now and Brexit.
In addition, it has been said that this is surrendering the power of Parliament to the Executive. To an extent that is true, but Parliament retains a veto in respect of every single regulation, either by a negative or an affirmative resolution. It is true that we do not want to have thousands of these if we can possibly avoid it, apart from anything else. But there is an element of control there. How practical that would be is, I think, doubtful. There is an urgent need now to circumscribe these powers so that they work properly and effectively but not excessively. As I said, a lot of people have worries about human rights, equality rights and a whole lot of other rights. Sometimes people have spoken in conversation or in observations to the press or whatever, which does not represent the Government’s policy. This helps to inflame the idea that the Government are using these powers to take away all that has been so dearly won. I do not think that is true, but we should try to remove the possibility that this idea can be represented.
