Mallard v Director of Public Prosecutions for Western Australia

In the case of Mallard v Director of Public Prosecutions for Western Australia, the appellant was convicted of multiple offences, including aggravated unlawful assault, two common assaults, and two firearm related offences. The appellant appealed the sentence imposed by the lower court. The central issues in the appeal were whether the sentences for the various offences were appropriate and whether the re-sentencing for the original common assault offence was based on an erroneous factual premise. Additionally, the appeal questioned whether the sentence for the aggravated unlawful assault was manifestly excessive and if the overall effective sentence complied with the first limb of the totality principle.

The court addressed the appeal by examining the facts of each offence and the reasons provided by the lower court for the respective sentences. It found that the re-sentencing for the common assault offence was flawed because it relied on an incorrect factual basis. Consequently, the court had to determine a new sentence for this offence based on its own assessment of the facts. Regarding the sentence for the aggravated unlawful assault, the court held that while the sentence was severe, it was not manifestly excessive given the nature and circumstances of the offence. The court also found that the effective sentence, when viewed through the lens of the first limb of the totality principle, was appropriate, considering the cumulative impact of all the sentences imposed.

The court, after re-evaluating the sentences and applying the relevant legal principles, ordered a new sentence for the common assault offence and upheld the sentences for the other offences. The final orders included a specific sentence for the re-assessed common assault offence and the affirmation of the sentences for the remaining charges.
