Hart v Commonwealth Director of Public Prosecutions

The High Court of Australia heard an appeal from the Federal Court of Australia concerning the validity of a search warrant. The appellant, Mr Hart, sought to challenge the legality of a search warrant issued under s 3E of the *Crimes Act 1914* (Cth) which authorised the search of his property. The Commonwealth Director of Public Prosecutions (CDPP) sought to rely on evidence obtained pursuant to that warrant.

The central legal issue before the High Court was whether the search warrant was validly issued. This required the Court to consider the proper interpretation of s 3E of the *Crimes Act 1914* (Cth), specifically the requirements for an issuing officer to be satisfied that there were reasonable grounds for believing that evidence relating to a federal offence would be found. The Court also had to determine whether the information provided to the issuing officer was sufficient to satisfy these requirements.

Gummow and Heydon JJ held that the search warrant was invalid. Their Honours reasoned that the information before the issuing officer did not establish reasonable grounds for believing that evidence relating to a federal offence would be found at the appellant's premises. The affidavit supporting the warrant contained insufficient particularity regarding the alleged federal offence and the connection between that offence and the premises to be searched. The Court emphasised that the issuing officer must be independently satisfied of the existence of reasonable grounds, and that a mere assertion by a law enforcement officer is not sufficient. The evidence obtained pursuant to the invalid warrant was therefore inadmissible.
