Telstra Corporation Ltd v The Commonwealth

In *Telstra Corporation Ltd v The Commonwealth*, the High Court of Australia considered a constitutional challenge brought by Telstra Corporation Ltd against the Commonwealth. The dispute arose from the Australian Competition and Consumer Commission's declaration of certain telecommunications services as "declared services" under the *Trade Practices Act 1974* (Cth). This declaration imposed obligations on Telstra, as the owner of the necessary infrastructure, to grant access to its facilities to other service providers for the purpose of offering these declared services in direct competition with Telstra.

The central legal issue before the High Court was whether the Commission's declaration and the consequent statutory obligation on Telstra to provide access to its infrastructure constituted an acquisition of property by the Commonwealth otherwise than on just terms, thereby contravening section 51(xxxi) of the Australian Constitution. Specifically, the Court was asked to determine if sections 152AL(3) and 152AR of the *Trade Practices Act 1974*, and other provisions within Part XIC of the Act, were beyond the legislative competence of the Parliament by reason of this constitutional provision, in their application to both the Unconditioned Local Loop Service (ULLS) and the Local Simulated Services (LSS).

The High Court reasoned that the legislative scheme did not effect a compulsory acquisition of property in the constitutional sense. While the provisions mandated access to Telstra's infrastructure, this was characterised as a regulatory measure aimed at promoting competition rather than a direct acquisition of property for the purposes of the Commonwealth. The Court held that the obligation to provide access on terms determined by agreement or, failing that, by the Commission, did not involve the Commonwealth taking property for its own use or benefit. Consequently, the Court concluded that the impugned provisions were within the legislative competence of the Parliament.

The High Court answered the questions reserved in the case stated by finding that sections 152AL(3) and 152AR of the *Trade Practices Act 1974*, in their application to both the ULLS and the LSS, were not beyond the legislative competence of the Parliament by reason of section 51(xxxi) of the Constitution. The Court also determined that it was not appropriate to answer questions concerning other provisions in Part XIC of the Act. Accordingly, Telstra was ordered to pay the costs of the case stated.
