High Court ruling may trigger legal fight over NSW's HVO coal expansion

A High Court ruling that struck down a Mount Pleasant mine approval for ignoring export-related emissions is expected to fuel a legal challenge to the HVO coal mine’s extension until 2045. HVO, a joint venture of Yancoal and Glencore in the Hunter Valley, was approved despite projected scope-3 emissions of roughly 800 million tonnes over 19 years, mainly from overseas use. Critics argue the Independent Planning Commission failed to assess the economic damage of those emissions to NSW.

While Premier Chris Minns says the decision is narrow, climate law specialists and industry analysts warn that the precedent could reshape approval processes and add pressure to the $68 billion Australian coal industry. The mine’s legal team anticipates writs and court action, and environmental groups are prepared to exploit the new legal landscape. The outcome could influence future export-oriented mining projects across the country.
