Mann v The Queen

The appellant, Mann, appealed against a sentence imposed by the District Court. He had been convicted of 11 offences committed between 31 May and 13 June 2015 and sentenced to 20 years imprisonment with a 16-year non-parole period. The appellant argued that the sentence was manifestly excessive.

The legal issues before the Court of Appeal concerned whether the sentencing judge erred in imposing the sentence, specifically whether the total sentence was manifestly excessive, and whether the principle of totality had been correctly applied. The Court was required to consider the circumstances of the offences, the appellant's criminal history, and the relevant sentencing principles, including the discretion of the sentencing judge and the grounds upon which an appellate court may intervene.

The Court found that while the offences were serious and committed over a relatively short period, the cumulative starting point of 19 years imprisonment was excessive when applying the totality principle. The Court noted that an appellate court will intervene if specific error is shown, or if the result is unreasonable or plainly unjust. In this instance, the Court determined that the sentence was disproportionate.

The appeal was allowed. The Court varied the sentence, imposing a total head sentence of 17 years imprisonment and a non-parole period of 13 years, seven months, and six days, back-dated to 13 June 2015. The sentence for the second firearm offence was ordered to be served concurrently with the sentences for the offences committed on 13 June 2015.
