A lawsuit from the Ku Klux Klan over adopting part of a highway in Union County for litter pickup may go forward to trial following a ruling from the Georgia Supreme Court. The Georgia Department of Transportation had denied a 2012 application from the KKK to the Adopt-A-Highway program, which requires volunteers remove litter from a roadway at least four times a year in exchange for a sign posted with the organization’s name. In a unanimous decision announced Tuesday, justices dismissed the state’s appeal of a lower court ruling.
