The battle over wind farms in Grey Highlands heads to the Ontario Superior Court in London on Tuesday.
Grey Highlands Clean Energy got the go-ahead for the nine unit wind turbine project some time ago.
Member of Grey Highlands Wind Concerns, Gary Fohr, is challenging the Environmental Review Tribunal (ERT) decision to allow a wind turbine project to proceed.
The hearing begins at 10 AM and will likely last all day.
Fohr says the Review Tribunal made an error in law when it misinterpreted an earlier Superior court ruling.
He claims that ruling stated the Tribunal must be able to prove that a wind turbine project will not cause relevant harm, prior to giving approval of a project.
Fohr says expert witnesses who testified at the ERT for the government and the wind company agreed under cross examination that there are no long term peer reviewed studies that can prove wind turbines are safe.
Up until now, it has been homeowners who had to offer proof that the turbines were harmful to them.
Fohr says after a number of ERT appearances and appeals, the Grey Highlands group is facing a legal bill of about 250 thousand dollars.
A nine-turbine project is to be located less than 1 km from the community of Brewster Lake in Grey Highlands.
