Cameron v the Queen

The High Court of Australia heard an appeal from the Court of Criminal Appeal of the Supreme Court of Western Australia concerning the sentencing of the appellant, Cameron, for a drug offence. The dispute centred on whether the appellant had entered his guilty plea at the first reasonable opportunity and, consequently, whether the sentencing judge had adequately discounted his sentence to reflect this.

The legal issues before the High Court were whether the appellant's guilty plea was entered at the first reasonable opportunity, given the initial misidentification of the prohibited drug in the complaint, and whether the sentencing judge erred in providing only a 10% discount for the plea, rather than the usual 20-35%. A related issue was whether the practice of providing a discount for a guilty plea, while not penalising an accused for exercising their right to trial, was discriminatory.

The High Court recognised that a plea of guilty is ordinarily a mitigating factor in sentencing, serving both as evidence of remorse and on the pragmatic ground of saving the community the expense of a trial. However, the Court clarified that sentencing is not a mathematical exercise and no rigid discount applies. The timing of the plea is crucial, with a plea entered at the first reasonable opportunity attracting a greater discount than a belated one. The Court distinguished between a discount for a plea of guilty and a discount for spontaneous remorse or immediate cooperation with police. Crucially, the Court held that a sentencing judge must not penalise an accused for exercising their right to silence or to put the prosecution to proof, but that doing so necessarily deprives the accused of any mitigation that might otherwise result from a guilty plea. The Court found that the Court of Criminal Appeal had erred in dismissing the appellant's appeal.

The High Court allowed the appeal, set aside the order of the Court of Criminal Appeal dismissing the appellant's appeal, and remitted the matter to that Court for further hearing and determination in accordance with the High Court's reasons.
