Boughey v the Queen

The High Court of Australia heard an appeal from a conviction for murder. The appellant, Mrs Boughey, was convicted of the murder of her husband, Mr Boughey. The central dispute concerned the appellant's mental state at the time of the killing and whether it amounted to a defence of provocation.

The High Court was required to determine whether the trial judge had adequately directed the jury on the defence of provocation, particularly in relation to the subjective and objective elements of the defence. Specifically, the court considered whether the jury had been properly instructed that they must be satisfied that the provocation was such as would have led an ordinary person to have lost self-control, and that the accused did in fact lose self-control. The court also considered whether the defence of provocation could apply where the deceased's conduct was not directed at the accused.

The High Court held that the trial judge's directions were inadequate. The court explained that provocation requires that the act of provocation must be such as to cause an ordinary person to lose self-control, and that the accused must have actually lost self-control. Furthermore, the court clarified that the conduct constituting provocation must be directed towards the accused, or at least be something that the accused perceives as being directed at them. The jury must be satisfied of both the subjective and objective elements of provocation.

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