HC Deb 16 February 1979 vol 962 c668W
Mr. Lee

asked the Secretary of State for the Home Department how many criminal convictions have been re-opened during the last five years, cited by special reference to the Court of Appeal (Criminal Division) or otherwise, as a result of the subsequent criminal conviction of police officers who had been prosecution witnesses at the original trials; and in how many such re-opened cases the matter at issue was the validity of the interrogation of defendants or the validity of statements taken under caution from such defendants.

Mr. John

During the period in question the convictions of two people were quashed after reference by the Home Secretary to the Court of Appeal following the conviction of three police officers, and three free pardons were granted as a result of the conviction of a police officer. It is not possible to establish how many cases which did not lead to action by the Home Secretary have been reopened as a result of the subsequent conviction of police officers nor what particular matters were at issue in any such cases
