Trainor v The Queen

The High Court of Australia considered an appeal by Trainor against his conviction for murder. The central dispute concerned the admissibility of a confession made by Trainor to police.

The High Court was required to determine whether the confession was improperly obtained, thereby rendering it inadmissible in evidence. Specifically, the Court had to consider whether the confession was voluntary and whether the police had acted unfairly or improperly in obtaining it, having regard to the circumstances in which it was made.

The Court applied the principles established in *R v Swaffield* and *Pollard v The Queen*, which require a confession to be voluntary to be admissible. A confession is not voluntary if it is obtained by violence, or by threats or promises, or by other improper means. The Court found that the police had engaged in a course of conduct that was unfair and improper, which rendered the confession inadmissible. This conduct included prolonged questioning and the use of inducements, which vitiated the voluntariness of the confession.

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