Approval of Adani's Queensland coalmine faces another legal challenge

Conservationists claim the state government failed to ensure the planned Carmichael mine was ecologically sustainable

Adani's plan for Australia's largest coalmine faces yet another snag, with a conservation group mounting what is now the eighth legal challenge to the contentious project.

The group, Land Services of Coast and Country, filed an appeal for a judicial review of the Queensland government's environmental approval of the Carmichael mine in the supreme court on Wednesday.
