X7 v The Queen

The High Court of Australia, constituted by French CJ and Kiefel J, considered an appeal by X7 against a conviction for a sexual offence. The central dispute concerned the admissibility of certain evidence during X7's trial.

The primary legal issue before the High Court was whether the trial judge had erred in admitting evidence of X7's prior sexual conduct with the complainant, which had occurred some years before the offence charged. This involved determining whether the evidence was relevant and, if so, whether its probative value outweighed any potential prejudice to the appellant.

The Court reasoned that the evidence of prior sexual conduct was relevant to establishing the context of the relationship between X7 and the complainant and was capable of demonstrating a pattern of behaviour. However, the Court also acknowledged the significant risk of prejudice that such evidence could pose to an accused. Applying the principles of relevance and prejudice, the Court concluded that the admission of this evidence was an error. The probative value of the evidence was not sufficiently high to justify the substantial risk of unfair prejudice to X7.

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