R v Cogley

In the matter of the Director of Public Prosecutions v Cogley, the Victorian Court of Appeal was tasked with evaluating the conviction of the appellant for murder and other related offences. The appellant was charged with the murder of a woman and several other serious offences, including causing serious injury by an act likely to endanger life. The primary dispute centred on the admissibility of certain propensity evidence, the joinder of the charges, and the applicability of the proviso under the Crimes Act 1958 (Vic.).

The court was required to determine whether the evidence of the appellant's previous acts of violence against women was admissible and whether the probative value of such evidence outweighed its prejudicial effect. Furthermore, the court had to consider whether the charges against the appellant should have been joined under section 398A of the Crimes Act 1958 (Vic.), and whether the proviso in section 568(1) applied to prevent the joinder of these charges.

The Court of Appeal held that the trial judge erred in admitting the propensity evidence as its prejudicial effect substantially outweighed its probative value. The court found that the evidence of the appellant's previous acts of violence, while relevant, was not necessary to establish the circumstances of the offence or any other fact in issue. Regarding the joinder of charges, the court held that the charges were part of a series of offences of a similar character, and thus the proviso under section 568(1) did not apply. Consequently, the joinder of the charges was deemed appropriate.

The Court of Appeal quashed the conviction and ordered a retrial on the charges of murder and causing serious injury by an act likely to endanger life. The court did not address the other charges as they were not the subject of the appeal.
