Xerri v The King

The High Court of Australia heard an appeal in *Xerri v The King*. The case concerned the proper application of the principles governing the admissibility of evidence of a defendant's prior convictions in criminal proceedings. The central dispute revolved around whether evidence of the appellant's previous convictions was unfairly prejudicial to the appellant and therefore inadmissible, or whether it was relevant to a fact in issue and properly admitted by the trial judge.

The High Court was required to determine whether the trial judge erred in admitting evidence of the appellant's prior convictions. Specifically, the Court had to consider whether the probative value of this evidence, in relation to the charges the appellant faced, outweighed its prejudicial effect. This involved an assessment of whether the evidence was capable of being used by the jury for an impermissible purpose, such as inferring guilt based on past conduct rather than on the evidence relating to the current charges.

The Court reasoned that evidence of prior convictions is generally inadmissible unless it has a direct bearing on a fact in issue in the current proceedings, beyond merely suggesting a propensity to commit the crime charged. In this instance, the High Court found that the evidence of prior convictions was admitted for the purpose of establishing the appellant's identity and his knowledge of the criminal enterprise. However, the Court concluded that the trial judge had failed to adequately direct the jury on the limited purpose for which the evidence could be used, thereby creating a substantial risk that the jury would use the evidence impermissibly to infer guilt. The Court held that the admission of the evidence, without sufficient limiting directions, resulted in a miscarriage of justice.

The High Court allowed the appeal, quashed the conviction, and ordered a new trial.
