Australian Manganese Pty Ltd/Western Australia/David Stock and Others on behalf of the Nyiyaparli People

In the matter of Australian Manganese Pty Ltd, the Western Australian government, and David Stock and others on behalf of the Nyiyaparli People, the Federal Court was tasked with determining whether the proposed grant of a mining lease over certain land could proceed, considering the registered native title rights and interests of the Nyiyaparli People. The Nyiyaparli People sought to ensure that any mining activities would not unduly impact their native title rights, particularly regarding their spiritual and cultural sites.

The central legal issue revolved around whether the proposed mining lease and its associated conditions would have a limited effect on the Nyiyaparli People's enjoyment of their registered native title rights and interests, as required by section 39 of the Native Title Act. The court also needed to consider if the future act, which included the grant of the mining lease along with specific endorsements and conditions, would have any effect on sites of particular significance to the Nyiyaparli People. Another issue was the potential impact of substantial amendments to the conditions post-grant, particularly if such amendments were imposed by the government.

The court found that the proposed mining lease and its conditions would have only a limited effect on the Nyiyaparli People’s enjoyment of their native title rights, and there would be no effect on sites of particular significance. The court determined that the future act included both the grant of the mining lease and the specified endorsements and conditions. It also considered the possible consequences of substantial amendments to these conditions after the grant, concluding that while the imposition of additional conditions by the government was not ideal, it did not render the future act invalid. The court ruled that the act could proceed with the specified conditions, thereby permitting the mining lease to be granted subject to those conditions.
