R v Hillier

The High Court of Australia considered the appeal of R v Hillier, where the appellant had been convicted of a number of offences, including aggravated robbery and assault occasioning actual bodily harm. The central dispute concerned the admissibility of evidence obtained from the appellant following his arrest, specifically a confession made to police.

The primary legal issue before the High Court was whether the trial judge had erred in admitting the appellant's confession into evidence. This involved determining whether the confession was voluntary, and if not, whether its admission would nonetheless be in the interests of justice, notwithstanding its involuntary nature. The court also considered the application of the exclusionary rule in relation to evidence obtained in breach of a suspect's rights.

The High Court held that the confession was inadmissible because it was not voluntary. The court found that the appellant had been subjected to oppressive questioning by police, which vitiated the voluntariness of his statement. Applying the exclusionary rule, the court determined that the admission of the confession would have been contrary to the interests of justice, as it was obtained in circumstances that were unfair to the appellant. Consequently, the High Court allowed the appeal, quashed the conviction, and ordered a new trial.
