Adams v The Queen

Adams appealed his conviction for armed robbery to the High Court of Australia. The appeal concerned the admissibility of evidence obtained through a search of the appellant's property.

The central legal issue before the High Court was whether the search warrant used to seize the evidence was validly issued, and consequently, whether the evidence obtained pursuant to that warrant was admissible in the trial. This involved an examination of the requirements for the issuance of search warrants under relevant legislation and the principles governing the admissibility of evidence obtained in breach of legal requirements.

The Court considered the provisions of the *Crimes Act 1914* (Cth) concerning search warrants. It was held that for a search warrant to be valid, the issuing officer must have reasonable grounds to believe that an offence has been, or is suspected on reasonable grounds to have been, committed. The Court found that the information before the issuing officer in this instance did not establish reasonable grounds for such a belief, rendering the warrant invalid. Consequently, the evidence seized was obtained unlawfully. The Court affirmed the principle that evidence obtained in contravention of a statute, even if relevant, may be excluded if its admission would be an affront to the proper administration of justice.

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