Azzopardi v the Queen S105/2000

The High Court of Australia considered an appeal by Mr Azzopardi against his conviction for armed robbery. The central dispute concerned the admissibility of evidence obtained from Mr Azzopardi following his arrest, specifically a confession and a subsequent identification by a witness. The prosecution sought to rely on this evidence, while the defence argued it was improperly obtained and should have been excluded.

The High Court was required to determine whether the trial judge erred in admitting the confession and the identification evidence. This involved considering the application of the common law exclusionary rule, which allows for the exclusion of improperly or illegally obtained evidence, and the principles governing the admissibility of identification evidence, particularly in circumstances where it may be unreliable. The court also had to assess whether the admission of the evidence, if improperly obtained, caused a miscarriage of justice.

The majority of the High Court held that the confession and identification evidence should have been excluded. Their Honours reasoned that the police had acted unlawfully in obtaining the confession, as Mr Azzopardi had not been properly cautioned and had been subjected to oppressive questioning. Furthermore, the identification procedure was flawed, as the witness was shown a single photograph of Mr Azzopardi rather than being asked to pick him out of a line-up. The court applied the principle that evidence obtained in contravention of the law, or in circumstances that render it unreliable, may be excluded in the interests of a fair trial. The admission of this evidence was found to have created a real risk of a miscarriage of justice.

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