Cameron v The Queen

In *Cameron v The Queen*, the High Court of Australia considered an appeal by the applicant, Cameron, against his conviction for murder. The dispute arose from the applicant's assertion that the trial judge had erred in law by failing to direct the jury on the defence of provocation, despite evidence suggesting the applicant had acted under provocation.

The central legal issue before the High Court was whether the evidence presented at trial was sufficient to raise the defence of provocation, thereby necessitating a direction to the jury on that defence. This involved an examination of the threshold required for evidence to be considered capable of supporting a defence, and the consequences of a failure to provide such a direction.

Gaudron and Kirby JJ, in their joint judgment, held that the trial judge had erred in law. Their Honours reasoned that the evidence, when viewed in a light most favourable to the applicant, was capable of supporting a finding that the applicant had acted under provocation. The defence of provocation, they stated, is available where the act of the accused was induced by a sudden or temporary loss of self-control caused by something done to the accused which would have had that effect on an ordinary person. The failure to direct the jury on this defence, therefore, meant that the applicant had not had the benefit of a complete defence being put to the jury, and his conviction was unsafe.

The High Court allowed the appeal, quashed the conviction for murder, and ordered a new trial.
