Attallah v Director of Public Prosecutions (NSW)

The High Court of Australia considered an appeal by Mr Attallah against a decision of the Director of Public Prosecutions (NSW). The dispute concerned the validity of a search warrant issued under the *Crimes Act 1900* (NSW) and the admissibility of evidence obtained pursuant to that warrant.

The central legal issue before the High Court was whether the search warrant was validly issued, specifically concerning the requirement that the issuing officer must have reasonable grounds to believe that an indictable offence had been, or was being, committed. This involved an examination of the nature of the belief required and the sufficiency of the information presented to the issuing officer.

The Court held that the issuing officer's belief must be based on reasonable grounds, meaning that the grounds must be such as would lead a reasonable person to form that belief. It was not sufficient for the issuing officer to merely accept the assertion of the informant without independent consideration of the information provided. The Court found that the information before the issuing officer in this instance did not establish reasonable grounds for the belief that an indictable offence had been committed, rendering the warrant invalid.

Consequently, the High Court allowed the appeal, quashed the search warrant, and declared the evidence obtained pursuant to it inadmissible.
