Campbell v Chief Executive, Department of Natural Resources and Water

In the case of Campbell v Chief Executive, Department of Natural Resources and Water, the dispute involved multiple appeals concerning valuation assessments for land subject to water depletion claims. The appeals were heard by the Administrative Appeals Tribunal (AAT), which was tasked with determining the impact of a mining operation on the water resources of the subject land. Specifically, the Tribunal had to assess whether the reduction in water availability due to the mining operation warranted a reduction in the unimproved value of the land.

The primary legal issues addressed by the Tribunal were whether the mining operation had indeed caused a depletion of water resources that fed bores on the subject land and, if so, to what extent this depletion affected the land's value. Additionally, the Tribunal had to consider the procedural aspect of whether additional written evidence could be tendered at the hearing, despite an earlier order for the exchange of evidence.

In its reasoning, the Tribunal held that the mining operation did not cause a measurable depletion of water resources affecting the subject land. The Tribunal found that the aquifers feeding the bores on the land were not significantly impacted by the mining activities. Furthermore, the Tribunal exercised its discretion under the applicable administrative law provisions and rejected the request to tender additional written evidence at the hearing, adhering to the previously ordered exchange of evidence. Consequently, the Tribunal dismissed all appeals, confirming the original valuation assessments.
