R v Campbell

The case of *R v Campbell* concerned an appeal by the applicant, Campbell, against his conviction for the offence of conspiracy to import a commercial quantity of a border-controlled drug. The prosecution alleged that Campbell had conspired with others to import cocaine into Australia. The central dispute revolved around the admissibility of certain evidence obtained by law enforcement agencies.

The High Court was required to determine whether the evidence obtained from the applicant's mobile phone, which had been seized pursuant to a search warrant, was admissible in the criminal proceedings. Specifically, the court considered whether the search and seizure of the phone, and the subsequent extraction and use of its contents, were lawful under the relevant provisions of the *Crimes Act 1914* (Cth) and the common law. A key issue was whether the police had exceeded their powers in seizing the phone and accessing its data.

The High Court held that the seizure of the mobile phone was lawful under section 3L of the *Crimes Act 1914* (Cth), which permits the seizure of evidential material. However, the court found that the subsequent accessing and use of the data contained within the phone went beyond the scope of the powers conferred by the warrant and the Act. The majority reasoned that while the warrant authorised the seizure of the phone as an item likely to afford evidence, it did not authorise the wholesale examination of its contents without further justification. This principle underscored the importance of adhering strictly to the statutory limitations on police powers of search and seizure, even when dealing with potentially incriminating evidence.

The appeal was allowed, and the conviction was quashed. The High Court ordered that the evidence obtained from the mobile phone be excluded from use in any retrial.
