Perkins v The Queen

The case of *Perkins v The Queen* concerned an appeal to the High Court of Australia by the applicant, Mr. Perkins, against his conviction for murder. The central dispute revolved around the admissibility of certain evidence obtained during police investigations and the subsequent fairness of the trial.

The High Court was required to determine whether the trial judge erred in admitting evidence that was obtained in circumstances that may have infringed the applicant's rights. Specifically, the court considered whether the admission of this evidence, despite potential breaches of the applicant's rights, was unfairly prejudicial to the applicant and therefore ought to have been excluded under the relevant evidentiary rules. A further issue was whether the cumulative effect of any errors at trial rendered the conviction unsafe or unsatisfactory.

Gageler and Gordon JJ applied the principles governing the admissibility of evidence obtained in breach of an accused's rights, particularly focusing on the balancing exercise required by s 137 of the *Evidence Act 1995* (NSW) (which was applied in the trial). Their Honours considered the probative value of the evidence against the risk of unfair prejudice to the applicant. They also examined the overall fairness of the trial process, taking into account the totality of the evidence and the directions given to the jury.

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