R v Harkin

The Director of Public Prosecutions appealed against sentences imposed by the District Court on John Harkin and Brendan Harkin, father and son, who had pleaded guilty to aggravated causing serious harm with intent. The sentencing judge had imposed terms of imprisonment of three years with an 18-month non-parole period for John Harkin, and two years and three months with a 12-month non-parole period for Brendan Harkin. Crucially, the judge ordered that both sentences be suspended upon the defendants entering into two-year unsupervised good behaviour bonds. The prosecution's appeal focused solely on the judge's discretion to suspend these sentences, arguing they were manifestly inadequate given the serious nature of the offence, which involved a revenge attack.

The appellate court was required to determine whether the sentencing judge erred in exercising their discretion to suspend the sentences of imprisonment. This involved considering the principles applicable to prosecution appeals against sentence, particularly in light of section 340 of the Criminal Law Consolidation Act 1935 (SA), and the appropriate approach to resentencing when the original sentences are deemed inadequate. The court also had to assess whether the judge adequately distinguished between the circumstances of the father and son, and whether any factors considered in favour of suspension were given inappropriate weight, such as the motivation for the offending conduct.

The court found that the sentencing judge had failed to adequately differentiate between the two defendants and had given inappropriate weight to the motivation for the offending conduct, treating it as a mitigatory factor when it was part of a revenge attack. Consequently, the sentences imposed were considered manifestly inadequate. The court allowed the appeals, set aside the original sentences, and resentenced John Harkin to a term of imprisonment of three years with a non-parole period of 18 months, declining to suspend the sentence. Brendan Harkin was resentenced to a term of imprisonment of two years and three months with a non-parole period of 12 months, with the sentence to be suspended upon his entry into a three-year supervised good behaviour bond, which included a condition for 200 hours of community service and undertaking anger management and other rehabilitation courses.
