When a judge sentences a young offender to a custody and supervision order under Section 42(2) (n) of the "Act", it means that the young offender must serve time in custody, followed by a period of supervision in the community. The supervision order may be up to half as long as the custodial period. This sentencing option is for convicted youth criminals who are convicted for crimes other than murder, attempted murder, manslaughter, aggravated sexual assault or who are in custody as a result of an IRCS (Intensive Rehabilitative Custody and Supervision) order.
