The Coal Action Network has been granted a full judicial review into the UK and Welsh governments decision to approve the mining licence at Aberpergwm colliery.
In the latest developments over the controversial coal mine at Aberpergwm near Glynneath, the grassroots campaign group will submit its case to a senior judge before the High Court challenging the lawfulness of the coal mine expansion plans approved by Coal Authority.
The organisation argues the licence will see more than 40 million tonnes of coal mined at Aberpergwm by operator Energybuild Ltd.
