Antarctic Bill

My hon. Friend makes a good point. There are different ways of doing these things. Perhaps there should be a combination of both. The Scrap Metal Dealers Bill, which passed through this House not long ago, had both, owing to an amendment that I tabled. It had a review that took place after three years; it also incorporates a sunset clause whereby, after five years, the Act would expire and would have to be brought back again if it was seen to be worth while. So I think my hon. Friend is on to something. But of course, it would be difficult to justify a sunset clause without a cost-benefit analysis to help us decide whether we wished to extend the legislation or wished it to expire.
