Landrey v Director of Public Prosecutions (NSW) & Ors

The High Court of Australia heard an appeal from the Supreme Court of New South Wales in *Landrey v Director of Public Prosecutions (NSW) & Ors*. The central dispute concerned the applicant's challenge to the validity of a search warrant issued under the *Crimes Act 1914* (Cth) and the subsequent seizure of certain electronic devices. The applicant contended that the warrant was invalid due to a failure to particularise the offence for which the search was authorised, arguing this rendered the warrant too broad and an unlawful exercise of power.

The High Court was required to determine whether the search warrant, which authorised the search for "data relating to [a specified person's] involvement in the commission of an offence against the law of the Commonwealth," sufficiently particularised the offence for the purposes of the *Crimes Act*. Specifically, the Court had to consider the level of specificity required in a warrant to ensure it was not a general warrant and complied with the statutory requirements for authorising a search.

In their joint judgment, Kiefel CJ and Jagot J held that the warrant was invalid. Their Honours reasoned that the wording "an offence against the law of the Commonwealth" was too vague and did not particularise the offence with the necessary specificity. They applied the principle that a search warrant must clearly identify the offence being investigated to prevent it from becoming a general warrant, which is unlawful. The Court found that the warrant failed to provide the executing officers with sufficient information to understand the nature of the suspected criminal activity, thereby exceeding the scope of the power conferred by the *Crimes Act*.

The High Court allowed the appeal, quashed the search warrant, and declared that the seizure of the electronic devices was unlawful.
