Victoria's Supreme Court has thrown out a case against the environmental regulator following allegations it had breached climate change legislation.
The court on Wednesday dismissed Environment Victoria's request to review an Environmental Protection Authority decision to alter the mining licences of three coal-fired power stations without imposing new restrictions on greenhouse gas emissions.
The conservation group said the EPA failed to consider Victoria's 2017 Climate Change Act in its licence reviews of the Yallourn, Loy Yang A and Loy Yang B stations.
