Summary: In Gloucester Resources Limited v Minister for Planning [2019] NSWLEC 7, the Land and Environment Court of New South Wales refused consent to a new open cut coal mine in a scenic valley near to the country town of Gloucester. There were five areas of contention: compatibility with existing, approved and likely preferred uses of the land in the vicinity of the mine, visual impacts, social impacts, economic and public benefits and climate change impacts.
This presentation will address these contentions, the methodologies and evidence the Court heard in assessing the balance between the benefits and impacts of the mine, notably in relation to climate change impacts, as this was the first time an Australian court heard expert evidence about the urgent need to stay within the global carbon budget in the context of a proposed new coal mine and findings that lead to the refusal of consent. The Court’s decision on climate change has reverberated around the world. Administrative decision-makers have adopted a similar approach and climate change litigation is citing the decision in support.
