Also, as you said, convener, the procedure should be affirmative rather than negative because if the powers were continually being brought back for the Parliament to approve, it would have a much greater opportunity effectively to block such orders at some point and say, "You have had your chance" and "Enough is enough; people cannot be left hanging on and waiting indefinitely for years into the future".Although I am happy with the extension of the time limit, it should be limited in some way and we should write to the promoters of the bill and ask them for their opinion on that point.
