HC Deb 23 July 1973 vol 860 c308W
Mr. Skeet

asked the Secretary of State for the Environment if he will list the number of times and the statutes in which retrospection has been authorised in Acts originating in his Department which have received the Royal Assent in the past three years.

Mr. Rippon
