High Court blocks coal mine expansion in historic climate ruling
Australia's High Court ruled planners must consider how exported coal harms local climate before approving mine expansions.
Australia's High Court has ruled against expanding the Mount Pleasant coal mine near Muswellbrook in the Hunter Valley. The ruling is the first climate change case to reach the High Court.
The court found that planning authorities must legally consider how exported coal will affect the local region through bushfire risk, drought, flooding and extreme heat. The Independent Planning Commission had failed this obligation when it approved the expansion without assessing these impacts.
The ruling creates a binding precedent across NSW and is expected to affect other states. It directly affects 17 coal proposals in the NSW planning system.
A grassroots community group fought the case through three court levels over four years.
