The State Government's making no apologies for having the Bob Brown Foundation slapped with a Worksafe Tasmania prohibition notice.
The Foundation, which has made headlines lately for its tree-sit blockades and equipment lock-ons at a West Coast logging coupe, is now banned from such activities.
"The notice prohibits the Foundation from carrying out forest protests throughout Tasmania, until such time the Foundation has satisfied the Work Health and Safety Regulator it is managing health and safety duties appropriately," said Attorney-General Elise Archer.
Flouting the ban would see the group fined up to $500,000; ex-Greens Leader Bob Brown says they're taking legal advice.
"I'm not going to be coerced by a bureaucratic decision which is a political fix by Premier Gutwein and his government," he told Local Radio.
"I think this is totally against the spirit of Australia's democratic freedoms."
Resources Minister Guy Barnett says the government is committed to protecting Tasmanians' right to work without being endangered, as well as rebuilding the state's forestry sector.
It follows last year's High Court setback for the Liberals which saw their controversial trespass laws gaoling activists overturned.
