Keech v The Queen

The appeal concerned the conviction of the applicant, Keech, for the offence of murder. The Crown alleged that Keech had intentionally caused the death of the deceased. The applicant appealed his conviction to the High Court of Australia.

The central legal issue before the High Court was whether the trial judge had erred in law by failing to adequately direct the jury on the defence of provocation. Specifically, the court considered whether the jury had been properly instructed on the subjective and objective elements of provocation, and whether the evidence presented at trial was capable of supporting such a defence.

McHugh and Callinan JJ, in their joint judgment, held that the trial judge's directions on provocation were insufficient. They explained that the defence of provocation requires the jury to consider whether the deceased's conduct was such as to cause an ordinary person to lose self-control and whether the applicant, in fact, lost self-control. The court found that the jury directions did not adequately convey these two essential components, particularly the objective element of what an ordinary person might do in response to the deceased's actions. The court concluded that the failure to provide adequate directions on provocation amounted to a miscarriage of justice.

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