Green v The Queen; Quinn v The Queen

These were appeals to the High Court of Australia concerning the admissibility of evidence obtained by police during a search of the appellants' premises. The appellants, Green and Quinn, were convicted of drug trafficking offences in the Supreme Court of New South Wales. The convictions were based, in part, on evidence seized during a search conducted under a warrant. The central issue on appeal was whether the evidence obtained from that search was admissible, given alleged irregularities in the execution of the search warrant.

The High Court was required to determine whether the evidence seized during the search was unlawfully obtained, and if so, whether it should have been excluded from admission at trial. Specifically, the Court considered the application of the exclusionary rule, which governs the admissibility of evidence obtained in contravention of legal rights or in circumstances where its admission would be unfair. The Court also had to consider the principles governing the exercise of judicial discretion to admit or exclude such evidence.

The Court reasoned that the search warrant, while validly issued, was not executed in accordance with the requirements of the relevant legislation. This led to the conclusion that the evidence was obtained in contravention of the appellants' rights. However, the Court ultimately held that the evidence was admissible. The majority applied the principle that where evidence is obtained in contravention of a legal right, it should only be excluded if its admission would be unfair to the accused or would bring the administration of justice into disrepute. In this instance, the Court found that the contravention was not so serious as to warrant exclusion, and that the probative value of the evidence outweighed any potential unfairness. The appeals were dismissed.
