Cook (a pseudonym) v The King

The High Court of Australia heard an appeal by a person, referred to pseudonymously as Cook, against their conviction for sexual offences against a child complainant. The central dispute concerned the admissibility of evidence relating to the complainant's prior sexual assaults by another individual. Cook sought to introduce this evidence and cross-examine the complainant about it, arguing it was relevant to the circumstances of the alleged offending and the relationship between Cook and the complainant.

The legal issues before the High Court were whether evidence of the complainant's prior sexual assaults was admissible under exceptions to section 293(3) of the *Criminal Procedure Act 1986* (NSW). Specifically, the court had to determine if the evidence fell within the exception in section 293(4)(a), which pertains to evidence forming part of a connected set of circumstances in which the alleged offending occurred, or section 293(4)(b), which relates to evidence concerning a relationship between the accused and the complainant. The court also considered whether the jury had been misled by the description of the prior assaults and whether an acquittal was necessary to avoid an unfair trial due to the inadmissibility of such evidence.

The High Court allowed the appeal in part. It reasoned that the exception in section 293(4)(a) did not apply to the evidence of the prior sexual assaults. However, the court indicated that the exception in section 293(4)(b) might apply at a retrial, subject to a consideration of evidence not before the court. The court found that any forensic disadvantage to the appellant from the inability to detail the prior assaults did not warrant an acquittal, but rather a potential retrial.

The High Court ordered that the appeal be allowed in part, setting aside an order of the New South Wales Court of Criminal Appeal and substituting an order that the appeal to that court be allowed on the basis of one ground and in part on another.
