Nov Sinn v The Queen

In the matter of Nov Sinn versus The Queen, the appellant, Nov Sinn, sought to appeal the sentence imposed by the County Court of Victoria. Sinn was convicted on two counts of trafficking a commercial quantity of cannabis and was sentenced to a total effective term of 5 years imprisonment, with a non-parole period of 3 years and 6 months. The primary legal issue was whether the disparity in the sentence imposed on Sinn and his co-offender contravened the principle of parity as established in the cases of Teng v R and DPP (Cth) v Peng, among others. Sinn contended that the minimal difference in sentencing could not be justified by individual differences in personal circumstances.

The Court of Appeal examined the principle of parity, which requires that sentences imposed on co-offenders should be comparable unless individual differences justify a variation. The Court considered that the individual differences in personal circumstances of Sinn and his co-offender were insufficient to justify the minimal differentiation in their sentences. The Court noted that the principle of parity was intended to ensure that co-offenders are not sentenced in a manner that is manifestly disproportionate, and that this principle was not satisfied in this instance. As a result, the Court allowed Sinn's appeal and remitted the matter back to the County Court for resentencing. The Court emphasised that the resentencing should take into account the principle of parity and ensure that the sentences imposed on Sinn and his co-offender are commensurate with the principles of justice.
