O'Brien v The State of Western Australia

The matter before the court was an appeal by the appellant against the sentence imposed on him by the Supreme Court of Western Australia. The appellant was convicted of multiple offences, including aggravated burglary, stealing, and fraud, as well as a breach of an intensive supervision order. The court was required to decide whether the sentence imposed on the appellant offended the totality principle and whether resentencing for the offence of aggravated burglary, in consequence of the breach of the intensive supervision order, was manifestly excessive.

The court considered the principle of totality in sentencing, which requires that the aggregate sentence imposed on a defendant for multiple offences should not be greater than the sum of the sentences that would have been imposed on each offence if they had been committed separately. The court held that the sentence imposed on the appellant for the offence of aggravated burglary, in consequence of the breach of the intensive supervision order, was manifestly excessive and did not take into account the appellant's previous non-custodial sentences for similar offences. The court also held that the aggregate sentence imposed on the appellant was manifestly excessive and did not take into account the appellant's previous non-custodial sentences for similar offences.

The court quashed the sentence imposed for aggravated burglary in consequence of the breach of the intensive supervision order and substituted a sentence of 8 months' imprisonment for that offence. The court also set aside the orders for cumulation and resentenced the appellant by cumulating the sentences for the other offences. The aggregate sentence imposed on the appellant was 34 months' imprisonment.

The court allowed the appeal and substituted the sentence imposed for aggravated burglary in consequence of the breach of the intensive supervision order with a sentence of 8 months' imprisonment. The court also set aside the orders for cumulation and resentenced the appellant by cumulating the sentences for the other offences. The aggregate sentence imposed on the appellant was 34 months' imprisonment.
