R v Karnage

This case concerned an appeal against sentence brought by the appellant, Karnage, before the Full Court of the Supreme Court of South Australia, constituted by Kelly, Nicholson and Hinton JJ. The appellant had been convicted of three offences of trafficking in a controlled drug and one offence of possessing a prohibited weapon. The primary dispute on appeal related to the sentencing judge's determination of the non-parole period, particularly in light of the appellant's status as a serious repeat offender.

The legal issues before the Court included whether the sentencing judge erred in classifying the appellant as a serious repeat offender under section 54(1) of the Controlled Substances Act 1984 (SA), thereby mandating a minimum four-fifths non-parole period. Relatedly, the Court considered whether the judge had properly applied section 54(2) of the Act, which allows for a lesser non-parole period if exceptional personal circumstances are demonstrated. The Court also had to determine if the judge had correctly calculated and applied the non-parole period in conjunction with the head sentence, given the concurrency of sentences for multiple offences.

The Court noted that the sentencing judge had found the appellant to have insight into his offending and a commitment to rehabilitation, but ultimately concluded that these personal circumstances were not exceptional enough to avoid the serious repeat offender declaration under section 54(2). Consequently, section 54(1) was applied, requiring a minimum four-fifths non-parole period. However, the judge imposed a non-parole period that was only extended by 12 months, which the Court observed appeared to negate the legislative intent of the mandatory minimum. Despite this apparent tension, and without argument from the respondent on the issue, the Court proceeded to consider the appeal on the basis of the judge's orders. The sentencing judge had imposed a head sentence of seven years imprisonment, largely concurrent with an existing sentence, and a non-parole period of four years, commencing from 2 September 2016.
