McNally v The State of Western Australia

The case of McNally v The State of Western Australia involved an appeal by the appellant, McNally, against his conviction on two counts of sexual penetration without consent. The conviction arose from a trial by jury. McNally contested the conviction on the basis that the trial judge made several errors during the trial process. These errors included concluding that there was no evidentiary basis for the operation of section 24 of the Criminal Code, withdrawing from the jury's consideration an issue of inconsistency relevant to the complainant's credibility, and failing to provide an adequate summary of the accused's case to the jury.

The legal issues before the court involved assessing the trial judge's handling of evidentiary matters and the adequacy of the jury's understanding of the accused's case. Specifically, the court had to determine if the trial judge erred in excluding evidence that could have been relevant under section 24 of the Criminal Code, whether the judge improperly limited the jury's consideration of inconsistencies in the complainant's testimony, and if the jury's comprehension of the accused's case was sufficiently guided by the trial judge.

The court's reasoning focused on the trial judge's discretion and the implications of the errors on the fairness of the trial. The court found that the trial judge's exclusion of evidence under section 24 was not erroneous as there was no evidentiary basis to support its application. Regarding the issue of inconsistency in the complainant's credibility, the court concluded that the trial judge did not improperly withdraw this issue from the jury's consideration. However, the court found that the trial judge did err in failing to give the jury an adequate summary of the accused's case. This omission was significant enough to potentially affect the fairness of the trial and the reliability of the jury's verdict.

The final orders of the court involved the reconsideration of the conviction in light of the identified error. The appeal was allowed, the convictions were quashed, and a retrial was ordered.
