R v Wilmot

The case of R v Wilmot involved an appeal against the appellant's conviction for murder by the Queensland Court of Appeal. The appellant had been convicted of murdering a man in what was described as an unprovoked assault. The primary issue before the court was whether the trial judge had misdirected the jury on the requirements of self-defence under section 271(2) of the Criminal Code 1899 (Qld). Specifically, the court needed to determine whether the trial judge erred by requiring the appellant to prove that the force used was objectively necessary for self-preservation, in addition to the requirement that the appellant honestly believed on reasonable grounds that he could not self-preserve otherwise.

The court held that the trial judge had indeed misdirected the jury. The trial judge should have instructed the jury to consider only whether the appellant honestly believed on reasonable grounds that he could not self-preserve other than by using the force he did. The court emphasised that in cases of unprovoked assault, the objective necessity of the force used is not an additional requirement for self-defence. The misdirection rendered the verdict unreasonable or unsafe, as the jury could not properly assess the plea of self-defence under the correct legal principles. Despite the strength of the prosecution's case, the court concluded that a properly directed jury might have found the appellant was acting in self-defence. Consequently, the appeal was allowed, the conviction for murder was set aside, and a re-trial was ordered.
