Hansen v The State of Western Australia

Hansen appealed to the High Court of Australia against a decision of the Supreme Court of Western Australia, which had dismissed his appeal against a conviction for murder. The central dispute concerned the admissibility of certain evidence obtained from the appellant, specifically statements made by him to police and a confession.

The High Court was required to determine whether the trial judge had erred in admitting the appellant's confession into evidence, given the circumstances under which it was obtained. Specifically, the court had to consider whether the confession was voluntary and whether the appellant had been properly cautioned and informed of his rights before making the statements. The admissibility of other statements made by the appellant to police was also in question.

The High Court found that the trial judge had not erred in admitting the confession. Their Honours applied the principles established in *R v Swaffield* and *Pollard v The Queen*, which require that a confession be voluntary to be admissible. The court held that the evidence did not establish that the appellant's will had been overborne by the police, nor that there was any inducement or threat that rendered the confession involuntary. The caution administered to the appellant was found to be adequate, and the circumstances of the questioning did not render the confession inadmissible.

The appeal was dismissed.
