Bennett v The State of Western Australia

In Bennett v The State of Western Australia, the defendant, Bennett, appealed against his conviction for possession of prohibited drugs with intent to sell or supply. The appeal was heard in the Supreme Court of Western Australia. The central issue in this case was the admissibility of evidence regarding Bennett's prior drug convictions, specifically whether such evidence could be considered as propensity evidence under the Evidence Act 1906 (WA), section 31A. Additionally, the court examined whether a previous conviction, obtained after the trial for the current offence, could be admissible as evidence of the fact of the conviction and the material facts comprising the elements of the earlier offence.

The court analysed the relevant provisions of the Evidence Act, particularly section 31A, which governs the admissibility of propensity evidence. It was established that evidence of a fact that an accused person has been convicted of an offence is not admissible to prove that the accused has a disposition towards criminal conduct of a particular kind or that the accused acted in conformity with such a disposition. However, the court found that evidence of the fact of the conviction and the material facts comprising the elements of the earlier offence could be admitted if it was incontrovertible. The court concluded that a previous conviction, obtained after the trial for the current offence, could be admissible as evidence of the fact of the conviction and the material facts comprising the elements of the earlier offence. However, in this case, the evidence was deemed inadmissible as it did not meet the criteria of being incontrovertible.

The appeal was dismissed, and leave to appeal was refused. The court upheld the lower court's decision, affirming Bennett's conviction. This decision highlights the importance of the incontrovertibility criterion when admitting evidence of prior convictions in criminal cases.
