§ Mr. Soleyasked the Secretary of State for the Home Department on how many occasions during 1982, the royal prerogative was exercised in order to adjust a custodial sentence where a person had been detained under a dual authority, as under the Criminal Justice Act 1967 and the Immigration Act 1971 prior to a conviction for a criminal offence.
§ Mr. MayhewOn 21 occasions. In all these cases the additional authority for the prisoner's detention, causing the time spent remanded in custody not to count towards a subsequent prison sentence, was an order under the Immigration Act 1971. By virtue of section 34 of the Criminal Justice Act 1982, concurrent detention otherwise than by order of court ho longer has this effect; thus, the exercise of the Royal Prerogative will no longer be necessary in such cases.
