DAWSONVILLE — Georgia’s highest court has dismissed appeals filed by a local couple against the city of Dawsonville over a motorsports park in western Dawson County.According to Tuesday’s unanimous opinion written by Supreme Court Justice David Nahmias, West and Helen Hamryka failed to follow the correct procedure when filing their appeals. Attorney Richard Wingate said his clients, whose home and horse farm sit adjacent to the Atlanta Motorsports Park on Duck Thurmond Road, are disappointed in the court’s decision. "We believe that we followed the proper appellate procedure because the Superior Court had previously ruled that this lawsuit was not filed as a review of an administrative decision," he said.
