The former Australian Greens leader wants Tasmania's Upper House to go to an election over its decision to send forest peace deal legislation to a parliamentary committee.
Last week, the Upper House voted to delay the forest peace deal legislation until at least next March.
MLCs are likely to meet this week to establish the terms of reference for their inquiry Bob Brown has labelled the Legislative Council's move a sideshow and a laughing stock.
"It ought to be put before the people of Tasmania, there should be a clear-out of the Legislative Council," he said.
He also wants the State and Federal Governments to ensure a World Heritage nomination which is part of the forest peace agreement goes ahead.
The Federal Environment Minister, Tony Burke, says the delay means the heritage nomination deadline in February will be missed.
Mr Brown says governments should not allow the delay to impact on the nomination covering forests in the Styx, Weld and Upper Florentine Valley.
"That can't wait the outcome of the Upper House faffing around until March at best so a bit of action is required here," he said.
The Liberals' spokesman Peter Gutwein supports the inquiry and says the State Government needs to answer tough questions, including how many jobs will be lost if the agreement goes ahead.
"That's a pretty basic but fundamental question the Government needs to answer," he said.
Federal Labor MP Julie Collins is urging the Federal Environment Minister not to withdraw $200 million in funding for the deal.
Mr Burke has confirmed the money is likely to be redirected for other uses.
A State Government spokesman says it will ensure there are no impediments to the parliamentary committee but it needs get on with the job.
