I would say to my hon. Friend the Member for Dunfermline Burghs (Mr. Adam Hunter) that I appreciate his concern. There was originally some misunderstanding about this, which prompted some of the opposition at that time. I am sorry that he spent four fruitless days dealing with this matter. We have clarified the point to some extent.
My answer to the hon. Member for Moray and Nairn (Mr. G. Campbell) is that the Secretary of State is consulted about this. I hope that will answer the point of the hon. Member for Edinburgh, South (Mr. Clark Hutchison), bearing in mind the local authority's own discretion and the Secretary of State's judgment—this can only be empirical; one cannot assess the nature of these things at the time.
