ENVIRONMENTAL group Save the Tarkine has launched another round of legal action against mining in the Tarkine.
Spokesman and patron Bob Brown said the group filed documents with the Federal Court in Melbourne today to challenge Venture Minerals proposed Riley Creek iron ore mine, which received federal approval in August.
The mine is expected to be worth $40 million a year to the Tasmanian economy.
Mr Brown said the challenge was based on former federal Environment Minister Mark Butler's alleged failure to properly consider the cumulative impact of a number of different mines that have received or are awaiting approval in the area, and failure to follow proper process in granting the approval before the Tasmanian Land Use Commission listed its concerns.
He said the group would also argue the requirement the developer pay a fine if a certain number of Tasmanian Devils are killed by mine activity, to be paid into a captive breeding program, did not fulfil the minister's obligation under federal law to maintain protected species in the wild.
The group has not requested an injunction and the hearing is expected to be on November 1 in Hobart.
Save the Tarkine lost an appeal against state approval of the mine with the Resource Management and Planning Appeals Tribunal two weeks ago.
It's the second time Save the Tarkine has challenged a mining licence in the Tarkine in the Federal Court.
It won a challenge against an iron ore mine operated by Shree Minerals, delaying the project by several months until Mr Butler re-approved the licence.
Mr Brown said the group was still waiting on legal advice about re-challenging that approval.
But he rejected the suggestion legal challenges just delayed proceedings, saying it was important to show when the a federal minister had not acted within the bounds of the law.
Tasmanian opposition mining spokesman Adam Brooks said today's legal challenge was another example of The Greens using a front group to stop progress.
``The fact is the Greens will do and say anything to stop mining in Tasmania, while Labor will continue to bend to the will of this extremist minority to stay in power,'' Mr Brooks said.
