Musarri v The Queen

The High Court of Australia considered an appeal by Musarri against his conviction for murder. The central dispute concerned the admissibility of evidence obtained through a covert recording of a conversation between the appellant and a police informant. The appellant argued that this evidence should have been excluded on the grounds that it was obtained in contravention of his rights, specifically his right to privacy and his right to silence.

The High Court was required to determine whether the admission of the covertly recorded conversation constituted a miscarriage of justice. This involved considering the scope of the common law right to privacy and its interaction with the admissibility of evidence obtained by law enforcement agencies. The Court also had to assess whether the admission of the evidence, even if improperly obtained, was so prejudicial to the appellant that it warranted quashing the conviction.

The Court ultimately held that the common law does not recognise a general right to privacy that would render evidence obtained by covert recording inadmissible. While acknowledging the importance of privacy, their Honours found that the law enforcement powers to investigate crime, including the use of informants and covert surveillance, were not inherently curtailed by such a right. The Court further reasoned that even if the evidence was improperly obtained, its admission did not necessarily lead to a miscarriage of justice, particularly where it was relevant and reliable. The appeal was dismissed.
