The plans for the wind farm, to be built in Stacain, Mid Argyll, were originally submitted for approval to Argyll and Bute council by Wind Prospect in 2005. The council gave the project the green light in 2007.
However, objections by Scottish National Heritage over the effect the wind farm could have on the local Golden Eagle population, resulted in the government calling a public enquiry and rejecting the plan.
Wind Prospect appealed the decision in the Court of Session. In the resulting case, the government admitted it had failed to take account new information proving the original estimates covering the wind farm's effect on the eagle population had been overestimated.
A spokesman for the Stacain project said: "Stacain wind farm has been in the planning process since 2005 and we are now hopeful that our application will be given full and due consideration. It is to be hoped that the clear scientific evidence, showing that there is no material risk to the eagle population, will be objectively considered and the wishes of the local democratically-elected council will be respected.
"It is completely impractical that we should find ourselves five years down the line with an undetermined planning application."
