Brennan v The King

The case of *Brennan v The King* concerned an appeal to the High Court of Australia from the Court of Criminal Appeal of Western Australia. The applicant, Cyril Thomas Brennan, had been convicted of manslaughter along with two co-accused, Flynn and Walsh, who had broken into a jeweller's shop and caused the death of the caretaker during the commission of the burglary. Brennan's role, as alleged by the prosecution, was to act as a lookout outside the shop.

The central legal issue before the High Court was whether the trial judge had correctly directed the jury regarding Brennan's criminal liability. Specifically, the court had to determine if it was a matter of law that Brennan's participation in the burglary as a lookout automatically rendered him guilty of the homicide committed by his confederates, or if this was a question of fact for the jury to decide based on the nature of the plan and Brennan's knowledge of his confederates' intentions. The court also considered the application of sections 7 and 8 of the *Criminal Code* (W.A.) concerning participation in offences and common intention to prosecute an unlawful purpose.

The High Court found that the trial judge had misdirected the jury. It was not a necessary legal consequence that if Brennan aided and abetted the shopbreaking by keeping watch, he was automatically criminally responsible for the homicide. The court reasoned that Brennan's guilt depended on the jury's findings regarding the specific plan to which he lent his aid and his knowledge of his confederates' intentions, particularly whether that plan involved the use of force against the caretaker. The jury's verdict of manslaughter against the co-accused implied they did not find the act causing death was likely to endanger life, which complicated the application of section 8 of the Code. However, the court concluded that the evidence did support the possibility that Brennan aided and abetted a criminal enterprise that he knew involved the use of some force against the caretaker to prevent interference.

Consequently, the High Court allowed Brennan's appeal, quashed his conviction for manslaughter, and ordered a new trial on the charge of manslaughter. The court determined that while the original direction was flawed, the evidence was sufficient to present the case to a jury, who would need to determine the factual questions regarding Brennan's knowledge and the nature of the common design.
