AK v Western Australia

The High Court of Australia heard an appeal by a male appellant against his conviction for indecent dealing with a child. The complainant, his younger cousin, alleged that the appellant had indecently dealt with her in February 2002, leading to a pregnancy in March 2003. The appellant was convicted on three counts of indecent dealing but acquitted of charges relating to later sexual offences. The appeal concerned the adequacy of the trial judge's reasons and the reasonableness of the verdict, particularly in light of the complainant's inability to visually or aurally identify the perpetrator.

The central legal issues before the High Court were whether the Court of Appeal erred in applying the proviso to the Criminal Appeals Act, thereby upholding the conviction despite the trial judge's failure to provide adequate reasons. This involved determining if a substantial miscarriage of justice had occurred. Additionally, the Court considered whether the verdict of guilt was unreasonable or unsupported by the evidence, given the nature of the identification evidence presented at trial.

A majority of the High Court, comprising Gummow and Hayne JJ, and Heydon J, allowed the appeal. Their reasoning focused on the trial judge's failure to provide adequate reasons for conviction, which constituted an error of law. This failure meant that the appellate court could not be satisfied that no substantial miscarriage of justice had occurred, thus precluding the application of the proviso. Heydon J also separately considered the ground that the verdict was unreasonable, finding that the complainant's identification evidence was insufficient to support a conviction beyond reasonable doubt. Gleeson CJ and Kiefel JJ dissented, finding that the proviso could be applied and that the verdict was safe.

Consequently, the High Court allowed the appeal, set aside the order of the Western Australian Court of Appeal, and ordered that the appellant's convictions be quashed and that there be a new trial.
