D'Arcy v The Queen

The case of *D'Arcy v The Queen* concerned an appeal to the High Court of Australia from a decision of the Supreme Court of Queensland. The appellant, D'Arcy, had been convicted of a number of offences, including armed robbery and unlawful use of a motor vehicle. The central dispute revolved around the admissibility of certain evidence obtained during police investigations.

The High Court was required to determine whether the evidence in question, which included statements made by the appellant and items seized from his property, had been obtained in contravention of the appellant's rights under the *Criminal Code* (Qld) and the *Police Powers and Responsibilities Act 2000* (Qld). Specifically, the court had to consider whether the appellant had been properly cautioned and whether his detention was lawful at the time the evidence was obtained.

McHugh and Hayne JJ, in their joint judgment, applied the principles established in *R v Swaffield* and *LMS v The Queen* regarding the admissibility of evidence obtained in contravention of statutory provisions. They held that where evidence is obtained in contravention of a statutory provision, the court must exclude that evidence unless the interests of justice require its admission. The court found that the police had failed to comply with their statutory obligations in obtaining the evidence, and that the interests of justice did not favour its admission.

Consequently, the High Court allowed the appeal, quashed the convictions, and ordered that the appellant be discharged.
