The Queen v Mamarika

The Queen appealed against a sentence imposed on the respondent, Mamarika, by the Supreme Court of the Northern Territory. Mamarika had pleaded guilty to unlawfully causing serious harm to his cousin. The Crown contended that the sentence of two years and three months imprisonment, suspended after nine months, was manifestly inadequate.

The legal issues before the Court of Appeal were whether the sentence imposed was so disproportionate to the objective circumstances of the offending as to constitute an error in principle, and if so, whether the Court should exercise its residual discretion to dismiss the Crown's appeal. The Court was required to consider the seriousness of the offence, Mamarika's criminal history, and the circumstances that had arisen since the imposition of the original sentence.

The Court found that the objective circumstances of the offending placed it in the middle range of seriousness, and that a starting point of three years imprisonment would have been more appropriate. Consequently, the sentence imposed was found to be manifestly inadequate, constituting an error in principle. However, at the time of the appeal hearing, Mamarika had already served eight months of his suspended sentence in his home community under supervision. The Court determined that allowing the appeal and resentencing Mamarika would disrupt his rehabilitation, cause him significant confusion, and result in unfairness. Therefore, the Court exercised its residual discretion to dismiss the appeal, despite the demonstrated error in the original sentencing.
