R v Dwyer

The appeal concerned the sentence imposed on the appellant, R v Dwyer, by the Supreme Court of South Australia. The appellant was convicted of multiple counts of armed robbery. The dispute on appeal related to the severity of the sentence imposed by the primary judge.

The Court of Criminal Appeal was required to determine whether the sentencing judge had erred in principle or imposed a sentence that was so disproportionate as to be manifestly unreasonable. This involved considering the appropriate sentencing range for armed robberies, particularly those involving threats of violence against vulnerable victims, and the relevance of the appellant's prior offending and parole status.

The Court applied the principles established in cases such as *R v Place*, which identified a standard sentencing range of six to eight years imprisonment for armed robberies of shops involving the use or appearance of weapons, particularly when committed by drug-addicted offenders to fund their addiction. The Court emphasised that general deterrence and public protection are paramount in such cases. While acknowledging that the standard range is not inflexible, the Court found that the circumstances of Dwyer's offending, including the use of a knife and machete and his recent relapse into serious crime while on parole, warranted a significant term of imprisonment. The Court also considered the sentencing judge's approach to calculating the head sentence, noting that while the judge did not identify separate notional sentences for each offence, the adopted starting point of 18 years was not demonstrably wrong and could be considered merciful.

The Court allowed the appeal, reducing the head sentence to 11 years, six months, and eighteen days. It also adjusted the non-parole period to eight years and ordered that the total sentence, including the unexpired balance of a previous sentence, be 15 years and twenty-seven days, commencing from 13 February 2014.
