The Federal Court of Australia ruled the creation of the tracks was likely to have a significant impact on the Tasmanian Aboriginal cultural landscape.

In her ruling Justice Debra Mortimer said the area had outstanding heritage value to the nation.

Members from the TAC cheered as the judgement was read out.

The case, between the TAC and the state Department of Primary Industries, Parks, Water and the Environment, was heard in the federal court last year.

An injunction against the tracks being opened was initially granted before a ruling was able to be handed down.

The TAC's Heather Schulthorpe said the decision was a victory for indigenous heritage in the state and urged the government not to appeal the decision. 

Environment, Parks and Heritage Minister Matthew Groom said the government notes the decision issued today by the Federal Court is very detailed and will therefore give it careful consideration.

``The government remains committed to striking the right balance that provides access for traditional recreational activities such as four-wheel driving whilst at the same time ensuring we protect its significant Aboriginal heritage values,'' Mr Groom said.
