Parker v The Queen

In *Parker v The Queen*, the High Court of Australia considered an appeal by the applicant, Parker, against his conviction for murder. The dispute centred on the admissibility of certain evidence and the directions given by the trial judge to the jury.

The primary legal issues before the High Court were whether the trial judge erred in admitting evidence obtained in breach of a statutory duty and whether the judge’s directions on the issue of self-defence were adequate. Specifically, the court had to determine if the admission of evidence obtained in contravention of s 138 of the *Evidence Act 1995* (NSW) was an error that rendered the conviction unsafe or unsatisfactory.

The High Court, in a joint judgment by Gaudron, McHugh and Kirby JJ, held that the admission of evidence obtained in contravention of s 138 of the *Evidence Act 1995* (NSW) was an error. Their Honours reasoned that the trial judge had failed to properly consider the factors outlined in s 138(2) when deciding whether to admit the unlawfully obtained evidence. The court found that the prejudicial effect of the evidence outweighed its probative value, and its admission was not justified. Furthermore, the court determined that the directions on self-defence, while not ideal, were not so inadequate as to constitute a miscarriage of justice in light of the overall evidence and directions.

Consequently, the High Court allowed the appeal, quashed the conviction for murder, and ordered a new trial.
