"The principle of totality comprises of two elements: (1) All courts, when sentencing for more than a single offence, should pass a total sentence which reflects all the offending behaviour before it and is just and proportionate. This is so whether the sentences are structured as concurrent or consecutive. Therefore, concurrent sentences will ordinarily be longer than a single sentence for a single offence. (2) It is usually impossible to arrive at a just and proportionate sentence for multiple offending simply by adding together notional single sentences. It is necessary to address the offending behaviour, together with factors personal to the offender as a whole."
