Graham on behalf of the Ngadju People v State of Western Australia

In Graham on behalf of the Ngadju People v State of Western Australia, the dispute revolves around the extinguishment of native title by various land grants and legislative regimes within Western Australia. The court was tasked with determining the validity of specific land grants and their impact on the native title rights of the Ngadju people. The case was heard in the Federal Court of Australia, with Justice Gilmour presiding.

The central legal issues before the court were whether certain land grants and legislative measures had the effect of extinguishing the native title rights of the Ngadju people. These issues included the validity of general purpose leases, exploration licences, prospecting areas, machinery areas, mineral claims, quarrying areas, mining leases, petroleum leases, and forestry regulations. The court had to consider the nature and effect of each of these instruments on native title, drawing on precedents and statutory interpretation.

The court's reasoning involved a detailed examination of each type of land grant and legislative measure. It found that certain general purpose leases, namely G15/17 and G63/4, were invalid under the "Ward Policy" and thus did not extinguish native title. The court also confirmed that exploration licences had no extinguishing effect, and prospecting areas and prospecting licences were similarly ineffective in extinguishing native title. Regarding machinery areas, the court held that while they did not extinguish native title, they did confer a right to control access. The court further found that mineral claims and quarrying areas, as regulated by the Mining Regulations 1925 (WA), did not extinguish native title beyond the right to control access. As for the mining leases, the court accepted that four of them were valid and extinguished native title, while the status of the remaining eight was inconclusive. Petroleum leases were found to cover the entire claim area but did not need to be further examined as other petroleum grants were already in place. Lastly, the court ruled that state forestry legislation did not extinguish native title but merely qualified the exercise of such rights.

The court’s final orders would likely detail the specific findings regarding the validity and effects of the various land grants and legislative measures on the native title rights of the Ngadju people, providing clarity on which rights were extinguished and which remained.
