Cao v The Queen

The High Court of Australia considered an appeal by Mr Cao against his conviction for murder. The central dispute concerned the admissibility of certain evidence obtained from Mr Cao following his arrest.

The primary legal issue before the High Court was whether the evidence, specifically a confession made by Mr Cao, was improperly obtained and therefore inadmissible under the common law. This involved an examination of the circumstances surrounding Mr Cao's arrest and the subsequent interview, including whether he was properly cautioned and whether his confession was voluntary.

The High Court held that the confession was admissible. Gleeson CJ and Crennan J reasoned that the police had acted appropriately in cautioning Mr Cao and that there was no evidence to suggest that the confession was not voluntary. The court applied the principles of the common law regarding the admissibility of confessions, which require that confessions be voluntary and not obtained by unfair means. The court found that the circumstances of the interview did not render the confession involuntary or unfair.

The appeal was dismissed.
