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

The dispute in this matter concerned the interpretation of a deed of settlement and release entered into between the State of Western Australia and the Northern Territory, represented by the Attorney-General of the Northern Territory, and the respondents, Ward and others. The proceedings were heard by Hayne J in chambers.

The central legal issue before the Court was whether the deed of settlement and release operated to extinguish the respondents' claims against the State of Western Australia for breaches of the *Native Title Act 1993* (Cth) that occurred prior to the execution of the deed. This involved a close examination of the language used in the deed and the surrounding circumstances of its formation.

Hayne J's reasoning focused on the principles of contractual interpretation, particularly the construction of release clauses. His Honour considered the ordinary meaning of the words used in the deed, giving due weight to the context in which they appeared. The Court determined that the language of the deed, when read as a whole, clearly indicated an intention to release the State of Western Australia from all claims, including those arising under the *Native Title Act 1993* (Cth), that were in existence at the time the deed was executed. The Court applied the established legal principle that clear and unambiguous language is required to effect a release of legal rights.

The Court ordered that the respondents' claims against the State of Western Australia for breaches of the *Native Title Act 1993* (Cth) occurring prior to the execution of the deed were extinguished by the deed of settlement and release.
