Ferris v The State of Western Australia

In the case of Ferris v The State of Western Australia, the central issue revolved around the admissibility of certain evidence in a criminal trial involving charges of fraud. The appellant, Mr Ferris, argued that the trial judge erred in admitting evidence of payments made by him to Mr O'Brien, one of the other accused. Ferris contended that this evidence should not have been admitted unless it met the criteria outlined in section 31A of the Evidence Act 1906 (WA), which pertains to propensity and relationship evidence. Ferris further argued that even if the evidence could be considered under section 31A, it was unduly prejudicial and should not have been admitted.

The court was tasked with determining whether the trial judge correctly admitted the evidence of payments from Ferris to O'Brien and if the evidence was correctly assessed under section 31A. The court considered whether the evidence had probative value in terms of motive and whether the risk of an unfair trial outweighed its probative value. Additionally, the court examined whether section 31A was the exclusive criterion for the admissibility of such evidence. The court held that the evidence was admissible not solely under section 31A but also because it was relevant to the motive of the accused. The court found that section 31A should not be interpreted as the exclusive determinant of admissibility for evidence within its scope.

The court concluded that the evidence of the payments was properly admitted as it was relevant to the motive of Mr O'Brien. The court rejected Ferris's argument that the evidence should have been excluded under section 31A. The appeal was dismissed, and leave to appeal was granted.
