Mullins v The Queen

In Mullins v The Queen, the High Court of Australia considered an appeal from a conviction for murder. The appellant, Mullins, had been found guilty of murder by a jury in the Supreme Court of Queensland and sentenced to life imprisonment. The appeal to the High Court concerned the interpretation and application of the law relating to provocation as a defence to murder.

The central legal issue before the High Court was whether the defence of provocation, as codified in the Queensland Criminal Code, required the jury to consider the subjective state of mind of the accused in determining whether the provocation was sufficient to reduce the offence from murder to manslaughter. Specifically, the court had to determine if the jury was entitled to find that the provocation was such as to cause an ordinary person to lose self-control, even if the accused themselves did not lose self-control in the same way or to the same extent.

Gaudron and Kirby JJ, in their joint judgment, affirmed that the defence of provocation requires a two-stage inquiry. First, the jury must determine whether the acts or words of the deceased were capable of constituting provocation. Second, they must consider whether the provocation was such as to cause an ordinary person to lose self-control. The judges emphasised that the standard is that of an ordinary person, not the particular characteristics of the accused, although the accused's characteristics may be relevant in determining whether the provocation was sufficient to cause an ordinary person to lose self-control. They found that the trial judge had correctly directed the jury on this matter, and that the jury's verdict was open to them on the evidence.

The appeal was dismissed.
