D'Arcy v Officers Still

The High Court of Australia considered an appeal by the applicant, D'Arcy, against the respondent officers. The dispute concerned the validity of a search warrant issued under the *Crimes Act 1914* (Cth) and the subsequent seizure of documents from the applicant's premises. The core of the applicant's challenge was that the warrant was invalid because it was not supported by sufficient evidence to establish reasonable suspicion that an offence against Commonwealth law had been, or was suspected of having been, committed.

The High Court was required to determine whether the issuing magistrate had a sufficient evidentiary basis to form the requisite reasonable suspicion for the purposes of authorising the search warrant under section 3E of the *Crimes Act 1914*. This involved an examination of the nature and quality of the information presented to the magistrate and whether that information, viewed objectively, could reasonably lead to the suspicion that a relevant offence had been committed.

The Court reasoned that the standard of proof for issuing a search warrant under section 3E of the *Crimes Act 1914* requires more than mere suspicion; it necessitates a reasonable suspicion based on credible information. The judges found that the information before the magistrate did not, in its totality, provide a sufficient evidentiary foundation to support a reasonable suspicion that the applicant had committed an offence against Commonwealth law. Consequently, the search warrant was deemed to have been improperly issued.

The High Court allowed the appeal, quashed the search warrant, and ordered that the documents seized pursuant to the warrant be returned to the applicant.
