Zecevic v Director of Public Prosecutions (Vic)

The High Court of Australia considered the appeal of Mr Zecevic against his conviction for murder, following a decision of the Supreme Court of Victoria. The central dispute concerned the application of the defence of self-defence to the charge of murder, specifically whether the jury had been adequately directed on the relevant legal principles.

The primary legal issue before the High Court was the correct test to be applied by a jury when considering a claim of self-defence in a murder trial. This involved determining whether the jury should assess the accused's belief in the need for force subjectively, or whether an objective standard should also be applied to the amount of force used. The Court also had to consider the relationship between the defence of self-defence and the offence of murder, particularly in light of the common law principles governing the use of force in self-preservation.

The High Court, in a joint judgment, clarified the law on self-defence. Their Honours held that the defence of self-defence requires an accused to establish that they acted in defence of themselves or another. The jury must first determine, on the balance of probabilities, whether the accused believed that it was necessary to use force to defend themselves or another. If the jury finds that such a belief existed, they must then consider whether the amount of force used by the accused was no more than was reasonably necessary in the circumstances as the accused believed them to be. This approach incorporates both subjective and objective elements, ensuring that the accused's genuine belief is considered alongside the reasonableness of the force used in those perceived circumstances. The Court affirmed that the onus rests on the prosecution to disprove self-defence beyond reasonable doubt once it is raised.

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