High Court Invalidates Mount Pleasant Expansion
Australia's highest court has ruled that the approval of MACH Energy's Mount Pleasant coal mine expansion in New South Wales' Hunter Valley was invalid. The 3-2 decision, delivered on Wednesday, found that the state's Independent Planning Commission (IPC) did not consider conditions to reduce greenhouse gas emissions that would result when the coal is exported and burned abroad. These emissions, known as scope 3, are not included in Australia's domestic emissions tally.[S1][S2]
MACH Energy brought the matter to the high court after the Denman Aberdeen Muswellbrook Scone Healthy Environment Group (Dams Heg), a local community organisation, had already stopped the expansion in the NSW court of appeal by arguing it was harmful to the climate. The decision establishes a precedent for fossil fuel developments in New South Wales and represents the first climate change case from Australia to be heard by the high court.[S1]
Political Reactions and Implications
Steph Hodgins-May, the deputy leader of the Greens, said the ruling makes it unmistakably clear to governments and fossil fuel corporations that the climate consequences of their projects cannot be disregarded or pushed into the future. She also noted that when coal from Australia is combusted in other countries, the resulting climate harm hits local communities through worse heat, drought, bushfires, and flooding.[S1]
Liberal leader Angus Taylor and Nationals leader Matt Canavan jointly expressed concern that the decision threatens Australia's reputation as a reliable energy exporter. They urged the federal and NSW governments to amend the law, specifically NSW's Environmental Planning and Assessment Act, to exclude consideration of overseas emissions from exported resources in project approvals.[S1]
Climate Change Minister Chris Bowen, currently in Fiji for climate negotiations, affirmed respect for the high court's interpretation of the law. Federal Environment Minister Murray Watt noted that the decision relates to a NSW government ruling based on NSW legislation and does not directly apply to Commonwealth decisions or legislation.[S1]
