DL v The Queen

The High Court of Australia considered an appeal by DL against a conviction for a sexual offence. The appeal concerned the admissibility of certain evidence and the fairness of the trial process.

The central legal issue before the High Court was whether the trial judge erred in admitting evidence of the complainant's prior sexual history, which the appellant argued was irrelevant and prejudicial. The Court also considered whether the cumulative effect of certain directions given by the trial judge to the jury, particularly concerning the assessment of the complainant's evidence and the appellant's character, rendered the trial unfair.

The High Court held that the admission of the evidence of prior sexual history was an error, as it did not meet the threshold for relevance and was likely to have unfairly prejudiced the jury against the appellant. Furthermore, the Court found that the cumulative effect of the judge's directions, when viewed in light of the improperly admitted evidence, created a substantial risk that the jury's verdict was not based on a proper consideration of the evidence. The Court applied principles of evidence law concerning relevance and prejudice, as well as the overarching principle of a fair trial.

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