R v Duncan

This case concerned a Crown appeal against a sentence imposed on the respondent, who had been convicted of a violent offence. The dispute centred on whether the original sentence was manifestly inadequate, failing to reflect the objective seriousness of the offending. The appeal was heard by Riley CJ, Southwood and Hiley JJ.

The legal issues before the Court were whether the sentence imposed was manifestly inadequate and, in light of the mandatory minimum sentencing provisions in the *Sentencing Act 1995* (NT), whether there were exceptional circumstances justifying a departure from such a minimum. The Court was required to determine if the original sentence was so disproportionate to the gravity of the offence that it shocked the public conscience.

The Court reasoned that while the respondent's subjective circumstances, including her youth, remorse, early guilty plea, and responsibility for her child, warranted considerable leniency, the objective seriousness of the stabbing offence was undeniable. The respondent had stabbed the victim with a knife, causing a life-threatening injury that required emergency surgery. The Court found that the original sentence was so disproportionate to the objective seriousness of the offending that it was manifestly inadequate and shocked the public conscience. Consequently, the appeal was allowed, the original sentence was set aside, and the respondent was resentenced. The Court noted that the mandatory minimum sentencing regime only applied if the otherwise appropriate sentence fell below the prescribed minimum, and in this instance, the need to consider exceptional circumstances did not arise as the appropriate sentence involved actual imprisonment.
