Stevens v The Queen

The High Court of Australia heard an appeal by Laurie Stevens against his conviction for the murder of his business partner, Murray Brockhurst. The deceased died from a gunshot wound to the head during an incident at their shared business premises. The appeal concerned the trial judge's refusal to direct the jury on the defence of accident under section 23 of the *Criminal Code* (Qld) and the availability of a manslaughter verdict.

The central legal issues before the High Court were whether the trial judge erred in declining to instruct the jury on the defence of accident, and whether this defence was open on the evidence presented. Relatedly, the court considered whether the jury should have been instructed that a conviction for murder required the prosecution to exclude the operation of section 23 of the *Criminal Code*. The court also had to determine if a verdict of manslaughter should have been left to the jury, and if the failure to provide these directions constituted a substantial miscarriage of justice.

The High Court allowed the appeal, finding that the defence of accident was indeed open on the evidence. The court reasoned that the appellant's own statements and the expert evidence regarding the firearm's propensity to discharge upon impact supported the possibility that the gun discharged independently of the appellant's will. This meant that the jury should have been given the opportunity to consider this defence. Furthermore, the court determined that the circumstances could have supported a verdict of manslaughter, particularly if the jury found the discharge of the weapon was not intentional but resulted from negligence. The court concluded that the failure to direct the jury on these matters resulted in a substantial miscarriage of justice.

Consequently, the High Court ordered that the appeal be allowed, the conviction be quashed, and that there be a new trial.
