Wrigley v The Queen

The case of *Wrigley v The Queen* concerned an appeal to the High Court of Australia by the applicant, Wrigley, against his conviction for murder. The central dispute revolved around the admissibility of certain evidence and the fairness of the trial proceedings.

The High Court was required to determine whether the trial judge had erred in admitting evidence obtained from the applicant, which the applicant argued was obtained in contravention of his rights. Specifically, the court considered whether the evidence was obtained in circumstances that rendered it unfair to admit, and whether the trial judge had adequately directed the jury on the issue of self-defence.

The Court's reasoning focused on the principles governing the admissibility of evidence obtained in contravention of an accused's rights, particularly in the context of the common law exclusionary rule and the discretion to exclude unfairly obtained evidence. The judges analysed the nature of the alleged contravention and its impact on the fairness of the trial. They also examined the adequacy of the jury directions concerning self-defence, considering whether the jury had been properly instructed on the relevant legal tests.

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