Two groups on Wednesday sued to overturn a law extending the elected terms of Georgia’s public service commissioners, saying it violates the state constitution for the five Republicans to be allowed to serve terms longer than six years.

Georgia WAND Education Fund, Georgia Conservation Voters Education Fund and Brionte McCorkle, the executive director of the conservation group, filed the suit in federal court in Atlanta. They allege that the law passed this year also violates their due-process rights under the 14th Amendment of the U.S. Constitution.
