R v Blackmore

The case of R v Blackmore involves an appeal by the Director of Public Prosecutions against the sentence imposed on the respondent, who was convicted of two robberies, one attempted robbery, and other related offences. The respondent, who was 18 years old at the time of the offending, stole a total of $16,716.00 in the two robberies, with one involving the claim that he was armed. The District Court Judge sentenced the respondent to a three-year imprisonment term, with a non-parole period of 18 months. The Director of Public Prosecutions appealed the sentence, arguing it was manifestly inadequate and failed to provide general deterrence.

The legal issues in the appeal centred around the principles governing the imposition of sentences for serious crimes and the role of general deterrence in sentencing. The appeal also examined whether the original sentence was manifestly inadequate in light of the respondent's circumstances, which included a difficult upbringing, no prior convictions, and a strong plan for future study. Additionally, the court had to consider the appropriate length of the non-parole period in relation to the head sentence and the need to balance the respondent's circumstances with the seriousness of the crimes.

The court, in allowing the appeal, noted the seriousness of the crimes and the necessity for general deterrence. It found the original sentence to be manifestly inadequate and increased the non-parole period by nine months. The court held that the respondent's background, while mitigating, did not outweigh the need to impose a sentence that reflected the seriousness of the crimes and provided general deterrence. The court substituted the original sentence with a six-year imprisonment term, with a non-parole period of 27 months, effective from 8 May 2003. The appeal was allowed, and the original sentence was set aside in favour of the substituted sentence.
