Colon Peaks Mining Co v Council of the Wollondilly Shire

The case of *Colon Peaks Mining Co v Council of the Wollondilly Shire* involved appeals to the High Court of Australia from decisions of the Supreme Court of New South Wales concerning the method of assessing rates on mining properties. The appellants were lessees from the Crown of mines situated on private land, where the Crown had reserved all minerals. The dispute centred on whether the unimproved capital value of the land, including the minerals, or the annual output of the mine should form the basis for calculating the rates payable by the mining lessees.

The primary legal issue before the High Court was the proper interpretation of section 132 of the *Local Government Act 1906* (NSW), specifically how it applied to mines situated on private land where minerals were reserved to the Crown. The court had to determine whether the "unimproved capital value of the land" could be assessed to include the value of the reserved minerals, or if the assessment for the lessees should be based on the "annual output of the mine" as provided for in the Act. A further question arose regarding the construction of the phrase "mine situate on Crown land and held from the Crown" in section 132(2)(b).

The High Court, in a majority decision (Griffith C.J. and Barton J., with O'Connor J. dissenting), held that section 132 of the *Local Government Act 1906* intended to draw a distinction between the "land" and the "mine" when dealing with leases from the Crown on private land with mineral reservations. The Court reasoned that where minerals are reserved to the Crown, they are not considered part of the private land for rating purposes. Consequently, the lessees of the mine, who held a separate tenement from the Crown, should have their rates assessed based on the annual output of the mine, as stipulated in section 132(2)(b), rather than the unimproved capital value of the land which included the minerals. The Court also clarified that the word "and" in the phrase "situate on Crown land and held from the Crown" could not be read as "or," reinforcing the distinction between different types of land tenure.

The appeals were allowed, and the decisions of the Supreme Court of New South Wales were reversed. The High Court ordered that the assessments made by the Council were invalid and that the rates should have been assessed according to the provisions relating to the annual output of the mine.
