Grivell v Mackley

This case concerned an appeal against sentence by two appellants, Grivell and Mackley, who had been convicted of assault causing harm. The appellants argued that their sentences and the imposed non-parole periods were manifestly excessive, and that the sentencing judge had failed to adequately consider the totality of their offending and the time they had already spent in custody. The offences involved a joint intention to assault a victim, followed by repeated assaults with kicks and a metal baton at an abandoned residence in Alice Springs.

The primary legal issues before the court were whether the sentences imposed were demonstrably too severe, and whether the non-parole periods exceeded the statutory minimum of fifty percent of the total head sentence. The court was required to assess the severity of the assault, considering the nature of the injuries sustained by the victim, and to weigh these against any mitigating factors presented by the appellants. The court also had to determine if the sentencing judge had given sufficient weight to the principle of totality and the pre-sentence custody.

The court found that while the injuries were not life-threatening, the victim had endured severe and painful beatings. The court applied established sentencing principles, including those from cases such as *Bugmy v The Queen* and *The Queen v Shrestha*, to assess the proportionality of the sentence. The court determined that the sentencing judge had erred in imposing sentences that were manifestly excessive, particularly in light of the mitigating circumstances and the totality of the offending. The court also found that the non-parole periods were incorrectly calculated.

Consequently, the appeal was allowed. The court quashed the original sentences and imposed new, reduced sentences and non-parole periods, reflecting a more appropriate assessment of the offending and the appellants' circumstances.
