Commentary First Group of Parts – Discipline Part 8 – Sentencing Powers and Mandatory Etc Sentences Section 214: Offences during currency of detention and training order
437.Where a person is convicted by a civilian court in England and Wales of an offence punishable with imprisonment which he committed during the supervision period of a detention and training order made by a civilian court, section 105 of the Sentencing Act enables the court convicting him to make an order for his detention for a further period, up to the period of supervision that remained outstanding at the date of the new offence. One effect of section 213 is that a civilian court in England and Wales has the same powers in the case of a person subject to a detention and training order made by a service court. Section 214 confers similar powers on the Court Martial and the SCC where they convict a person of a service offence punishable with imprisonment and committed during the supervision period of a detention and training order made by a service court.
438.The Court Martial can also exercise these powers if the offender was convicted of the new offence by a civilian court anywhere in the British Islands, or at a summary hearing. In this case the court can issue a summons or a warrant for the offender’s arrest, so that it can consider whether to exercise its powers.
