State of New South Wales & Ors v Commonwealth of Australia

The High Court of Australia heard a dispute between the State of New South Wales and other States (the applicants) and the Commonwealth of Australia (the respondent). The core of the disagreement concerned the validity of certain provisions of the *Native Title Act 1993* (Cth) and their application to the extinguishment of native title rights. Specifically, the applicants challenged the Commonwealth's power to enact legislation that, in their view, retrospectively validated certain past acts that had extinguished native title, thereby interfering with the States' legislative and executive powers.

The central legal questions before the Court were whether the impugned provisions of the *Native Title Act 1993* (Cth) were constitutionally valid, particularly in light of the division of powers between the Commonwealth and the States under the Australian Constitution. The applicants argued that these provisions infringed upon the residual legislative powers of the States and that the Commonwealth had exceeded its constitutional authority in enacting them. The Court was required to consider the scope of the Commonwealth's legislative power, including its power to make laws with respect to the people of any race, for whom it is deemed necessary to make special laws, and its power to implement international treaty obligations.

The Court's reasoning focused on the interpretation of section 109 of the Constitution, which provides for the paramountcy of Commonwealth law where there is an inconsistency between Commonwealth and State legislation. The majority of the Court held that the *Native Title Act 1993* (Cth) was a valid exercise of the Commonwealth's legislative power, including its power to legislate in relation to external affairs and its power to make special laws for the people of any race. The Court found that the provisions in question did not impermissibly encroach upon the constitutional powers of the States, as the Commonwealth had a legitimate interest in ensuring the uniform application of native title law across Australia and in fulfilling its international obligations. The Court distinguished between the extinguishment of native title by the Crown and the validation of past acts that had that effect, concluding that the Commonwealth had the power to validate such acts.

The High Court dismissed the application, upholding the constitutional validity of the relevant provisions of the *Native Title Act 1993* (Cth).
