Gazepis v Police

In *Gazepis v Police*, the High Court of Australia considered an appeal from a decision of the Supreme Court of Tasmania. The appellant, Mr. Gazepis, had been convicted of a number of offences under the *Tasmanian Racing Act 1983* (Tas) and the *Criminal Code Act 1924* (Tas). The central dispute concerned the interpretation of certain provisions of the *Tasmanian Racing Act 1983* relating to the conduct of bookmaking operations and the admissibility of evidence obtained through surveillance.

The High Court was required to determine whether the appellant's activities constituted illegal bookmaking under the relevant legislation, and whether the evidence obtained by police surveillance, which included audio recordings and observations, was lawfully obtained and admissible in court. A key legal issue was whether the surveillance activities, which involved entering private property without a warrant, were authorised by the *Tasmanian Racing Act 1983* or whether they constituted an unlawful trespass.

The Court analysed the provisions of the *Tasmanian Racing Act 1983* concerning the powers of inspectors and police officers to conduct investigations into illegal bookmaking. It considered the scope of the statutory authority granted for surveillance and the limitations imposed by common law principles, particularly the right to privacy and protection against trespass. The Court ultimately found that the statutory provisions did not grant the broad powers of entry and surveillance that the police had purported to exercise, and that the evidence obtained through these means was therefore unlawfully obtained and inadmissible. The Court applied principles of statutory interpretation, emphasising that powers of this nature must be clearly and unambiguously conferred by legislation.

The High Court allowed the appeal, quashed the convictions, and ordered that the evidence obtained through the unlawful surveillance be excluded.
