Collins v The Queen

Collins appealed to the High Court of Australia against his 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 appellant argued that these statements were involuntary and therefore inadmissible under the common law.

The High Court was required to determine whether the trial judge had erred in admitting the appellant's confession into evidence. This involved considering the principles governing the admissibility of confessions, particularly the requirement that they be voluntary and not obtained by unfair means. The court also had to assess whether the trial judge had properly applied these principles to the facts of the case.

The High Court held that the trial judge had not erred in admitting the confession. Their Honours applied the established common law principles regarding the admissibility of confessions, which require the prosecution to prove beyond reasonable doubt that a confession was voluntary. The court found that the evidence did not establish that the confession was induced by threats, promises, or other improper pressure. Consequently, the confession was properly admitted as evidence.
