Reg v Swaffield- Pavic v The Queen

The High Court of Australia considered appeals by Swaffield and Pavic against their convictions for offences under the *Customs Act 1901* (Cth). The central dispute concerned the admissibility of evidence obtained through electronic surveillance, specifically the use of a listening device, and whether this constituted an unlawful search or seizure under the *Australian Constitution*.

The primary legal issue before the Court was whether the use of a listening device by Commonwealth officers, without a warrant, constituted an unlawful invasion of privacy and therefore rendered the evidence obtained inadmissible. This raised questions about the existence and scope of an implied right to privacy in the Australian Constitution, and whether such a right could be abrogated by Commonwealth legislation.

The Court, by majority, held that there is no implied right to privacy in the Australian Constitution that would render the use of listening devices unlawful in the absence of a warrant. Brennan CJ, Toohey and Gaudron JJ found that the *Customs Act* authorised the use of such devices, and that the common law did not prohibit their use in a manner that would render the evidence inadmissible. Kirby J, dissenting, argued for the recognition of an implied right to privacy, but acknowledged that Parliament could legislate to override such a right. Gummow J's reasoning focused on the specific provisions of the *Customs Act* and the absence of any constitutional prohibition.

The appeals were dismissed, with the convictions upheld.
