State of WA - A-G of NT v Ward & Ors

The High Court of Australia considered an appeal by the State of Western Australia and the Attorney-General of the Northern Territory against a decision of the Full Court of the Supreme Court of Western Australia. The dispute concerned the interpretation and application of the *Aboriginal Heritage Act 1972* (WA) and the *Aboriginal Heritage Act 2003* (NT) in relation to certain Aboriginal traditional owners and their claims to native title over land.

The central legal issues before the High Court were whether the respondents, as traditional owners, had established native title rights and interests in the areas in question, and whether the appellants had lawfully extinguished those rights and interests through various legislative and executive actions. Specifically, the court had to determine the extent to which the *Aboriginal Heritage Act 1972* (WA) and the *Aboriginal Heritage Act 2003* (NT) impacted upon native title claims and whether the extinguishment provisions within these Acts were valid and effective.

The High Court's reasoning focused on the principles of native title extinguishment under Australian law, particularly in light of the *Mabo* decision and subsequent legislation. The judges examined the nature of the rights asserted by the respondents and the effect of the appellants' actions, including the granting of pastoral leases and other interests, on those rights. The court applied established legal principles regarding the extinguishment of native title by the Crown, considering whether the relevant legislative provisions and executive acts were of a character that necessarily extinguished native title. The court also considered the interaction between the *Native Title Act 1993* (Cth) and the state and territory heritage legislation.

The High Court allowed the appeal in part, finding that certain native title rights and interests had been extinguished by the actions of the State of Western Australia and the Northern Territory. The court remitted the matter to the Federal Court of Australia for further determination of the extent of native title rights and interests that had not been extinguished.
