There is a good deal to be said for the amendment moved by the noble Lord, Lord Sharkey, when one bears in mind the power given in each of Clauses 7, 8 and 9 to make any provision that could be made by an Act of Parliament under regulations made under these clauses. Of course, one can look back to an existing Act, which could be amended by the exercise of this power, for a purpose related to the Brexit arrangements. If one takes an
existing Act—one can visualise all sorts of situations when that might arise—it would seem right that the same procedure should apply if the amendment is made for the purposes which one sees in Clauses 7, 8 and 9.
For future Acts I can see there is a problem, because one cannot control a future Parliament, but as far as the past is concerned I respectfully suggest that there is a lot to be said for the amendment.
