RUMNEY MLC Tony Mulder has dramatically upped the stakes in the battle to preserve the fragile forest peace deal.
Mr Mulder tabled a new motion to assess the deal's viability, which could result in the Legislative Council killing off the deal.
The move came on the same morning the Government tabled its response to the Special Council's durability report, which raised serious concerns about wood supply under the peace deal.
The forest peace deal's reserves are subject to a disallowance period, whereby the Legislative Council can confirm or reject the reserves over the next two months.
Describing it as a tactical move, Mr Mulder indicated he was ready to bring on a debate on the matter, which could happen as soon as tomorrow.
However, the Government releasing its response to the durability report could slow a potential debate as Legislative Councillors consider its findings.
Mr Mulder said he was keen to see progress from the Government on his key issue, support to regional sawmillers.
The Government response confirms Forestry Tasmania is set to meet wood supply contracts and customer requirements for high quality sawlogs and peeler logs in 2013 and 2014.
Huon MLC Paul Harriss tabled a similar disallowance motion last week, but said he was not going to bring on the debate until a longer consideration of issues, which could include a ''short and sharp'' Legislative Council inquiry.
