Mullavey v Haoma North West N.L

This matter came before the High Court of Australia on an application for special leave to appeal. The applicant, Terrance Patrick Mullavey, sought to challenge decisions of the Full Court concerning mining legislation. The dispute centred on whether "trailings," described as material above the natural surface, constituted "land" or "Crown land" within the meaning of the relevant Act, and consequently, whether an application for a mining lease in respect of such trailings was permissible.

The legal issues before the court included whether the current mining legislation contemplated applications for mining leases in respect of different strata of land, and if so, how such applications would interact with existing rights, particularly in relation to pre-existing trailings. The applicant argued that the Act, by comparison with earlier legislation, implicitly allowed for strata titles, and that the absence of express provisions against it, coupled with certain references in older Acts, supported this interpretation. The court also considered the treatment of pre-existing trailings under the current legislation and the implications of transitional provisions.

The applicant contended that the Minister's power to impose limitations and reasonable conditions under section 84(2) of the Act would enable co-existence between a mining lease for the ground and a lease for the trailings, analogous to the situation under repealed legislation. However, the court expressed reservations about this interpretation, with Brennan J noting that such an approach could lead to "mining chaos" and questioning whether the statutory rights conferred by section 85(2)(a) were subject to such ministerial limitations. The applicant conceded that this interpretation would involve "stretching the words" of the subsection.
