Keech v the Queen M157/2002

This matter concerned an appeal to the High Court of Australia by the applicant, Keech, against his conviction for murder. The applicant had been convicted in the Supreme Court of Queensland and subsequently appealed to the Court of Appeal of Queensland, which dismissed his appeal. The dispute before the High Court centred on whether the trial judge had erred in his directions to the jury regarding the defence of provocation.

The primary legal issue before the High Court was whether the jury had been adequately instructed on the objective elements of provocation, specifically concerning whether the conduct of the deceased was such as to cause an ordinary person to lose self-control. The court was required to consider whether the trial judge’s directions, when read as a whole, conveyed the correct legal test for provocation, taking into account the subjective state of mind of the applicant and the objective standard of an ordinary person.

McHugh and Callinan JJ, in their joint judgment, found that the trial judge’s directions on provocation were flawed. They held that the jury had not been clearly instructed that the question of whether an ordinary person would have lost self-control was a question of fact for the jury to determine, based on the evidence. Their Honours emphasised that the jury must be satisfied that the deceased’s conduct was capable of causing an ordinary person to lose self-control, and that this was a crucial element of the defence that had not been sufficiently explained. The appeal was allowed, the conviction was quashed, and a new trial was ordered.
