M v Shire of Kalamunda

In the case of M v Shire of Kalamunda, the defendant appealed against their conviction for the demolition of a building without a permit. The defendant, who was the owner of the land on which the building stood, did not personally carry out the demolition work but was convicted under section 22 of the Criminal Code (WA). The legal issues before the court were whether the defendant could be held criminally responsible for the actions of a third party and whether the learned magistrate erred in failing to consider the defence of honest claim of right, and if that defence was open on the evidence. The court found that there was no evidence of a mistaken belief by the defendant that the demolition was permitted.

The court examined whether the defendant could be held criminally responsible for the acts of another person. The court acknowledged that under section 22 of the Criminal Code, a person can be held responsible for the acts of another if they intentionally assisted, encouraged, or facilitated the commission of the offence. However, the court noted that there was no evidence to suggest that the defendant had any involvement in the demolition work itself, nor had they encouraged or facilitated it. The court then turned to the defence of honest claim of right, which requires the defendant to have an honest belief that they had the legal authority to carry out the act in question.

The court held that the learned magistrate had erred in failing to consider the defence of honest claim of right, as it was open on the evidence. The court noted that the defence required an honest belief, not a reasonable one, and that there was no evidence to suggest that the defendant did not genuinely believe that they had the legal authority to demolish the building. The court found that the defence was not available to the defendant, as there was no evidence of a mistaken belief on their part. The court concluded that the conviction should be quashed and a verdict of not guilty entered in its place.

The final orders of the court were to quash the conviction and enter a verdict of not guilty. The court found that the defendant could not be held criminally responsible for the acts of another in the circumstances of this case and that the defence of honest claim of right was not available to the defendant due to the absence of any evidence of a mistaken belief. The court acknowledged that the defendant's conduct was unlawful but found that there was insufficient evidence to support a conviction under section 22 of the Criminal Code.
