Massey v The Queen

Massey appealed his conviction for murder in the Supreme Court of Queensland. The central issue on appeal concerned the admissibility of evidence obtained from a search of the appellant's mobile phone. The prosecution sought to rely on text messages found on the phone, which they argued were relevant to establishing the appellant's motive and intent. The appellant contended that the search of his phone was unlawful and that the evidence derived from it should have been excluded.

The High Court of Australia was required to determine whether the search of the appellant's mobile phone was conducted in accordance with the law, specifically whether it was authorised by a search warrant that adequately described the place to be searched and the things to be seized. The Court also had to consider the principles governing the admission of evidence obtained in breach of a statutory provision, particularly the discretion to exclude such evidence where its admission would be unfair to the accused.

The High Court held that the search warrant was invalid because it failed to sufficiently particularise the place to be searched, thereby rendering the search of the mobile phone unlawful. The Court affirmed that evidence obtained in contravention of a statutory provision is not automatically inadmissible, but that courts retain a discretion to exclude such evidence. In exercising this discretion, the Court must weigh the public interest in the conviction of those guilty of crime against the public interest in the due administration of justice and the protection of individual rights. Applying these principles, the Court found that the admission of the unlawfully obtained text messages was unfair to the appellant and that the conviction should be quashed.

The High Court allowed the appeal, quashed the conviction, and ordered a new trial.
