HC Deb 03 December 1959 vol 614 cc155-6W
100. Mr. Ginsburg

asked the Secretary of State for the Home Department what guidance he has given, comparable to that given to the Metropolitan Police and the Customs in 1951 and 1956, to other authorities regarding application for warrants to intercept telephone conversations.

Mr. R. A. Butler

Appendix II of the Report of the Committee on the Interception of Communications makes it clear that applications from authorities other than the Metropolitan Police, the Board of Customs and Excise and the Security Service are very rare. It has not yet been found necessary to give other authorities guidance on the conditions which the Secretary of State requires to be satisfied before authorising interception. The same principles are applied in considering applications whatever their source, and if the conditions are not satisfied the application is refused.
