AB (A Pseudonym) v The Queen

The High Court of Australia considered an appeal by AB (a pseudonym) against a conviction for a sexual offence. The dispute centred on the admissibility of certain evidence during the trial.

The primary legal issue before the High Court was whether the trial judge erred in admitting evidence of the appellant'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 its prejudicial effect, particularly in light of the appellant's defence.

Gageler J, delivering the judgment of the Court, reasoned that the evidence of prior sexual conduct was relevant to establishing the nature of the relationship between the appellant and the complainant and to rebutting the appellant's defence that the sexual activity was consensual. His Honour applied the principles governing the admission of such evidence, emphasising the need for a careful balancing of its potential to prove an element of the offence or rebut a defence against the risk of it unfairly prejudicing the appellant in the eyes of the jury. The Court found that the trial judge had properly conducted this balancing exercise.

The appeal was dismissed.
