Doyle v The Queen

The case of *Doyle v The Queen* concerned an appeal to the High Court of Australia following a conviction for murder. The appellant, Doyle, had been found guilty of murder by a jury in the Supreme Court of Queensland and subsequently appealed to the Court of Appeal of Queensland, which dismissed his appeal. Doyle then sought and was granted special leave to appeal to the High Court.

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 question was whether the judge's summing up had sufficiently explained the objective element of provocation, namely whether the provocation was such as to cause an ordinary person to lose self-control.

The High Court, comprising Gleeson CJ and Gummow J, held that the trial judge's directions on provocation were inadequate. Their Honours reasoned that the jury must be instructed that the question of whether the provocation was sufficient to cause an ordinary person to lose self-control is a question of fact for the jury to determine, and that the judge's summing up had not made this sufficiently clear. The legal principle applied was that a proper direction on provocation requires the jury to consider both the subjective state of the accused and the objective standard of an ordinary person.

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