Bufton v The King

In *Bufton v The King*, the applicant, Bufton, sought to appeal against his conviction for murder. The appeal was heard by Gleeson J of the Supreme Court of New South Wales. The central dispute concerned the applicant's contention that the trial judge had erred in law by failing to direct the jury adequately on the issue of self-defence.

The primary legal issue before the Court was whether the trial judge's summing up to the jury sufficiently explained the elements of self-defence, particularly in relation to the applicant's belief as to the necessity of using force and the proportionality of that force. The applicant argued that the jury may have been misled into believing that the defence required an objective assessment of the reasonableness of his actions, rather than focusing on his subjective belief at the time.

Gleeson J considered the relevant legal principles governing self-defence in New South Wales, drawing upon established case law. His Honour emphasised that the defence of self-defence operates by negating the element of unlawfulness in the act of killing. The focus of the jury's inquiry, in relation to the subjective limb of self-defence, is on what the accused believed at the time of the act, not on what a reasonable person would have believed. The judge's summing up was scrutinised to determine if it adequately conveyed this subjective test to the jury, ensuring they understood that if the applicant genuinely believed he was acting in self-defence, even if that belief was mistaken, the defence could be established.

The appeal was allowed, the conviction was quashed, and a new trial was ordered.
