Cheung v The Queen

In *Cheung v The Queen*, the High Court of Australia considered an appeal from a conviction for murder. The appellant, Cheung, had been found guilty of murder by a jury in the Supreme Court of New South Wales and subsequently appealed to the Court of Criminal Appeal of New South Wales, which dismissed his appeal. The High Court then granted special leave to appeal.

The central legal issue before the High Court was whether the trial judge had erred in law by failing to direct the jury adequately on the defence of provocation. Specifically, the court had to determine whether the evidence presented at trial was capable of supporting a finding that the appellant had acted under a sudden or temporary loss of self-control induced by provocation, thereby reducing the charge of murder to manslaughter.

The High Court analysed the evidence in detail, considering the appellant's account of the events leading up to the killing. The majority of the Court held that there was sufficient evidence of provocation to warrant a direction to the jury. They emphasised that the question of whether provocation had occurred, and whether it had caused a loss of self-control, was a matter for the jury to determine. The legal principle applied was that where there is some evidence, however slight, that might support a defence, the judge must direct the jury on that defence.

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