TEC Desert Pty Ltd v Commissioner of State Revenue (WA)

The High Court of Australia considered an appeal by TEC Desert Pty Ltd and AGL Energy Holdings Pty Ltd (the appellants) against the Commissioner of State Revenue (WA). The dispute concerned whether a Sale Agreement between the appellants and WMC Resources Ltd ("WMC") effected a conveyance on sale of an interest in land, thereby attracting stamp duty. The core of the disagreement lay in the classification of certain "Fixtures" as defined in the Sale Agreement, particularly those affixed to land subject to WMC's mining tenements.

The legal issues before the Court were whether the Sale Agreement transferred an interest in land, whether an interest in items affixed to land subject to mining tenements constituted an interest in land, and whether such items qualified as "Fixtures" under the Sale Agreement's definition. Additionally, the Court had to consider whether an obligation for the appellants to acquire WMC's rights in "Fixtures" on WMC's freehold land, or certain covenants related to those licences, created interests in land.

The Court reasoned that the definition of "Fixture" in the Sale Agreement required an item to be affixed to land and for an estate or interest in that item to be an estate or interest in land. It held that items affixed to land did not automatically become "fixtures" in the technical sense merely by their affixation. Furthermore, items classified as "mining plant" under the relevant legislation, and which were part of a mining lease (considered personal property), did not, by virtue of their affixation, assume the character of an estate or interest in land for stamp duty purposes. The Court noted that the Sale Agreement itself distinguished between chattels sold outright and "Fixtures" treated under licence agreements.

The High Court allowed the appeal, setting aside the order of the Court of Appeal of Western Australia and ordering that the appeal to that Court be dismissed with costs. The parties were given a period to file agreed short minutes of further orders, failing which the matter was to be remitted to the Court of Appeal.
