Optus Fixed Infrastructure Pty Limited v State of Queensland & Anor

Optus Fixed Infrastructure Pty Limited (Optus) sought judicial review of decisions made by the State of Queensland and the Chief Executive of the Department of Resources. The dispute concerned the validity of certain conditions imposed by the State on Optus's telecommunications infrastructure development under the *Acquisition of Land Act 1967* (Qld) and the *Land Title Act 1994* (Qld). Optus contended that these conditions were beyond the scope of the relevant legislative powers and unlawfully fettered its statutory rights. The matter was heard by the High Court of Australia.

The central legal issues before the High Court were whether the conditions imposed by the State were authorised by the relevant legislation, specifically concerning the acquisition of land for telecommunications infrastructure and the registration of interests in land. Optus argued that the conditions imposed were not for a purpose contemplated by the legislation and that the State had acted *ultra vires* in imposing them. The court was required to interpret the scope of the powers granted to the State under the *Acquisition of Land Act 1967* and the *Land Title Act 1994* in relation to the development and registration of telecommunications infrastructure.

The High Court found that the conditions imposed by the State were not authorised by the *Acquisition of Land Act 1967* or the *Land Title Act 1994*. Kiefel CJ and Steward J held that the statutory framework did not permit the State to impose conditions that effectively created a proprietary interest in favour of the State or third parties, or that imposed obligations on Optus beyond those necessary for the proper registration of its interest. The court applied principles of statutory interpretation, emphasising that powers conferred by statute must be exercised within the limits prescribed by the legislation and that conditions imposed must be for a purpose authorised by the statute. The court concluded that the conditions were *ultra vires* and therefore invalid.
