The Pearce principle against double punishment does not require quashing a conviction on a second count where two offences arise from a single act but have different legal elements, provided the sentencing judge differentiates the criminality of each offence and applies the totality principle. Where an aggregate sentence is imposed, it makes no sense to speak of concurrency; the relevant question is whether the aggregate sentence properly reflects the totality of criminality without disproportionate weight being given to common underlying facts. Indicative sentences recorded under s 53A(2) of the CSP Act are not themselves amenable to appeal.
