Coalition will take six to eight weeks to revise its Carmichael coalmine approval

Environment department says federal court decision to overturn Greg Hunt's approval for $16bn project was 'technical, administrative matter'

The federal government has said it will take six to eight weeks to reconsider its approval of Queensland's Carmichael coalmine after the federal court halted what would be Australia's largest mine.

The court ruled that the approval of Adani's Carmichael mine was invalid because the federal environment minister, Greg Hunt, had not fully assessed its impact on two vulnerable species: the yakka skink and the ornamental snake.
