R v Guode

The High Court of Australia considered an appeal by the Crown against a decision of the Court of Appeal of the Supreme Court of Queensland. The appeal concerned the interpretation of section 13.1 of the *Criminal Code* (Qld) and its application to the appellant's conviction for an offence under that section.

The central legal issue before the High Court was whether the trial judge had erred in law by directing the jury that the appellant's subjective belief as to the existence of a fact, which if true would render his conduct lawful, was irrelevant to the question of whether he possessed the requisite *mens rea* for the offence. Specifically, the Court had to determine the correct legal test for establishing criminal responsibility under section 13.1 of the *Criminal Code* (Qld) in circumstances where the accused claims a mistaken belief regarding a factual circumstance.

The High Court held that the trial judge's direction to the jury was erroneous. The Court reasoned that section 13.1 of the *Criminal Code* (Qld) requires the prosecution to prove beyond reasonable doubt that the accused intended to do the act that constitutes the offence, and that the accused knew that the act was of a kind that was likely to constitute the offence. A genuine and reasonable belief that the act was lawful, even if mistaken, could negate the necessary intention or knowledge. The Court affirmed that the subjective belief of the accused, if genuinely held and reasonable in the circumstances, is a relevant consideration for the jury when assessing *mens rea*.

The High Court allowed the Crown's appeal, quashed the acquittal, and remitted the matter to the Court of Appeal of Queensland to determine whether a new trial should be ordered.
