Koani v The Queen

The High Court of Australia considered an appeal by the appellant, who had been convicted of murder in the Supreme Court of Queensland. The conviction arose from the death of his de facto partner, which was occasioned by a shotgun discharge while the appellant was holding the weapon. The appellant had pleaded guilty to manslaughter, acknowledging a gross breach of his duty to exercise reasonable care in the use of the dangerous item, as stipulated by s 289 of the *Criminal Code* (Q). However, the prosecution did not accept this plea, and the jury ultimately found the appellant guilty of murder.

The central legal question before the High Court was whether an unwilled, criminally negligent act or omission, which results in death, could form the basis of a murder conviction under s 302(1)(a) of the *Criminal Code* (Q) if the jury was satisfied that the accused possessed the intention to kill or inflict grievous bodily harm. This question also encompassed whether a breach of the duty to use reasonable care and take reasonable precautions with a dangerous item could, in itself, found a conviction for murder.

The High Court reasoned that criminal responsibility for murder, both under the *Criminal Code* and at common law, cannot be established by an unwilled act. The Court clarified that the identification of the act giving rise to criminal responsibility for murder under the *Code* is not confined more narrowly than under the common law. Therefore, an unwilled, criminally negligent act, even if it causes death, cannot sustain a murder conviction if the act itself was not intended to cause death or grievous bodily harm.

The appeal was allowed. The order of the Supreme Court of Queensland (Court of Appeal) was set aside, and in its place, it was ordered that the appellant's appeal to that Court be allowed, his conviction quashed, and a new trial be had.
