Collins v The Queen

Collins appealed his conviction for murder in the Supreme Court of New South Wales. The central dispute concerned the admissibility of a confession made by Collins to police. The High Court of Australia was required to determine whether the confession was improperly obtained and therefore inadmissible, or whether it was lawfully obtained and properly admitted into evidence at trial.

The legal issues before the High Court were whether the trial judge erred in admitting the confession, and whether the confession was obtained in circumstances that rendered it involuntary or otherwise inadmissible at common law. This involved an examination of the voluntariness of the confession, considering whether Collins was induced to confess by threats or promises, or whether his will was overborne by the circumstances of his questioning.

The High Court held that the confession was admissible. The judges reasoned that the evidence did not establish that the confession was involuntary. They applied the common law principles governing the admissibility of confessions, which require that a confession must be voluntary to be admitted into evidence. The court found that the questioning of Collins, while persistent, did not amount to coercion or oppression that would render his confession involuntary. The trial judge's decision to admit the confession was therefore upheld.
