Duong v The Queen

The appeal concerned the sentence imposed on the appellant, Mr Duong, who pleaded guilty to supplying a commercial quantity of cannabis. The appeal was heard by Southwood, Kelly, and Hiley AJ in the Supreme Court of the Northern Territory. The central dispute revolved around whether the sentencing judge had made an error of law by making an incorrect factual finding, or whether the sentence was manifestly excessive.

The legal issues before the Court were whether the sentencing judge erred in their assessment of the appellant's role in the drug enterprise, and consequently, whether the imposed sentence of five years imprisonment, suspended after three years, was manifestly excessive. The appellant argued that the sentencing judge made an error of fact by finding he played a significant role, when competing possibilities existed regarding his level of involvement.

The Court considered the principles governing appellate intervention in sentencing, particularly in cases involving alleged mistakes of fact. While acknowledging that different burdens of proof apply to the Crown and the offender, the Court affirmed that the same principles regarding factual findings must apply to sentencing. The sentencing judge had noted significant "unknowns" regarding the appellant's precise role, including the identity of the supplier, the financing of the purchase, and the appellant's expected benefit. Despite these unknowns, the judge concluded that the appellant had played a "very significant role" in transporting a large quantity of cannabis to Darwin, and could not mitigate the sentence on the basis of him being a mere driver. The Court found that the sentencing judge's assessment was open to them on the admitted facts and the evidence presented, and that the sentence was well within the permissible range for such an offence.

The appeal was dismissed, with the Court concluding that the sentence imposed was not manifestly excessive and that no error of law had been made by the sentencing judge.
