Abisaab v The Queen

The High Court of Australia considered an appeal by Mr Abisaab against his conviction for a number of offences, including conspiracy to import a commercial quantity of heroin and conspiracy to possess a commercial quantity of heroin. The appeal concerned the admissibility of certain evidence obtained by the Australian Federal Police.

The central legal issue before the High Court was whether the evidence obtained by the Australian Federal Police, which included intercepted communications and seized items, was admissible in the criminal proceedings against Mr Abisaab, given the circumstances of its acquisition. Specifically, the Court had to determine if the evidence was obtained in contravention of statutory provisions governing the use of listening devices and the execution of search warrants, and if so, whether it should have been excluded under the relevant evidence legislation.

The Court's reasoning focused on the interpretation of the *Crimes Act 1914* (Cth) and the *Broadcasting Services Act 1992* (Cth) in relation to the authorisation and execution of surveillance operations. It was held that the evidence obtained through the use of a listening device was unlawfully obtained because the warrant authorising its use was defective. However, the Court applied the proviso to s 138 of the *Commonwealth Evidence Act 1995* (Cth), finding that the unfairness to the accused occasioned by the admission of the unlawfully obtained evidence did not outweigh the public interest in making available to the court all material evidence relevant to the determination of guilt.

The appeal was dismissed.
