Commentary First Group of Parts – Discipline Service of sentence Section 302: Remission of certain sentences on passing of custodial sentence etc
588.This section applies where a person is already serving a relevant sentence (defined as a sentence of service detention, a service supervision and punishment order or a minor punishment) and, during that sentence, is sentenced in separate proceedings to a custodial sentence, either in respect of a service offence or by a civilian criminal court. Where this occurs, the unserved balance of the relevant sentence is to be remitted. This means that the person will cease to serve the relevant sentence and will instead immediately commence the new custodial sentence in the appropriate establishment. The person does not remain liable to serve any unserved part of their sentence, which is effectively cancelled.
