Shumack v Australian Federal Police Commissioner

In *Shumack v Australian Federal Police Commissioner*, the High Court of Australia considered an appeal concerning the validity of a search warrant issued under the *Crimes Act 1914* (Cth). The appellant, Mr. Shumack, sought to challenge the legality of the search of his property and the subsequent seizure of items, arguing that the warrant was invalidly issued. The core of the dispute revolved around whether the issuing officer had reasonable grounds to believe that the premises to be searched were connected with an indictable offence.

The High Court was required to determine whether the issuing officer, in forming the requisite belief for the issuance of the search warrant, was entitled to rely on information provided by a confidential informant. Specifically, the Court had to consider the nature and extent of the information that an issuing officer must have before them to be satisfied that there are reasonable grounds for believing that a search warrant should be issued under section 3E of the *Crimes Act 1914*. This involved an examination of the statutory requirements for the issuance of such warrants and the standard of proof required.

The Court reasoned that the issuing officer must be satisfied on the material before them that there are reasonable grounds for the belief. This satisfaction is a subjective one, but it must be based on objectively reasonable grounds. The High Court affirmed that an issuing officer is entitled to rely on information provided by a confidential informant, provided that the information is sufficiently detailed and credible to enable the officer to form a reasonable belief. The Court found that the information before the issuing officer in this instance was sufficient to satisfy the statutory requirements, and therefore the warrant was validly issued.
