Multiple-offence sentencing: courts may order concurrent or consecutive terms subject to statutory limits; aggregate treated as single sentence appeal. A court convicting a person of multiple offences at one trial may impose the separate prescribed punishments and, after considering offence gravity, order them to run concurrently or consecutively. Consecutive sentences that produce an aggregate exceeding the single offence competence do not alone mandate reference to a higher court; statutory caps limit cumulative punishment. For the purpose of appeal, the aggregate of consecutive sentences is deemed a single sentence.
