Roberts v The Queen

Roberts appealed his conviction for murder in the Supreme Court of Queensland. The central issue on appeal concerned the admissibility of certain evidence, specifically a confession made by the appellant to police. The High Court of Australia was required to determine whether the trial judge had erred in admitting this confession, given the circumstances under which it was obtained.

The High Court considered the application of the exclusionary rule concerning confessions obtained in circumstances where the accused has been induced to confess by threats or promises, or where the confession is otherwise involuntary. The court examined the evidence presented at trial regarding the interview process and the appellant's state of mind at the time of making the confession. It was necessary to assess whether the confession was made freely and voluntarily, or if it was tainted by improper police conduct.

In their joint judgment, Hayne and Callinan JJ affirmed the principles governing the admissibility of confessions, emphasising that a confession must be voluntary to be admissible. They found that the trial judge had correctly applied these principles and had not erred in admitting the confession into evidence. The appeal was accordingly dismissed.
