The mine was first knocked back in December 2017, but Gloucester Resources Limited (GRL), the privately owned company behind the proposal, was granted the right to appeal the decision.
Summing up his judgement on Friday, Preston said: “In short, an open cut coal mine in this part of the Gloucester valley would be in the wrong place at the wrong time.
“Wrong place because an open cut coal mine in this scenic and cultural landscape, proximate to many people’s homes and farms, will cause significant planning, amenity, visual and social impacts.
“Wrong time because the greenhouse gas emissions of the coal mine and its coal product will increase global total concentrations of greenhouse gases at a time when what is now urgently needed, in order to meet generally agreed climate targets, is a rapid and deep decrease in greenhouse gas emissions. These dire consequences should be avoided.”
