Perdue also elevated Carl Bowers from traffic court to the higher division of Cobb State Court, filling the vacancy created by the resignation of Beverly Collins. Eric Brewton, who previously worked with Mike Bowers in the state Attorney General's office, will replace Bowers in traffic court.
It is unclear when the appointments take effect.
Reuben Green, who earlier this year intended to run for state court, is a former Cobb assistant district attorney, and most recently served as Special Assistant U.S. Attorney. He also worked in the DeKalb County Solicitor General's Office and was an attorney with the Atlanta law firm of King and Spalding.
"I got the call from the governor a little while ago, and it's a pretty surreal experience," Green said Friday evening. "I'm honored and I'm humbled, and I hope I do a good job."
Green said he did not know when he will be sworn in. Cobb has 10 Superior Court judges.
Green is a graduate of Emory University School of Law and received his bachelor's degree from Lewis and Clark College in Portland, Ore. His wife, Heidi, is Commissioner of Georgia's Economic Development agency. The couple lives in Marietta and has two children.
Nix, 70, tendered his resignation a few weeks ago, amid rumors that complaints were being filed against the judge for inappropriately touching two women in the district attorney's office. He said he had planned to retire in December, but tendered his resignation, effective Oct. 4.
Green said of that situation, "It's an unfortunate circumstance that brought us to this position, but I'd like to look forward."
In Cobb State Court, Division II Judge Carl Bowers will be moving up to Division I, which can hold jury trials. Bowers has been on the bench in the traffic court since 2005 and was previously in private practice for six years.
He replaces Collins, the wife of Cobb District Attorney Pat Head, who retired June 30. Bowers also served as a judge in the Cobb County Magistrate Court for four years, and was a prosecutor in Cobb's Solicitor General's Office.
Carl Bowers earned both his undergraduate and law degree at the University of Georgia. He and his wife, Ingrid, live in Acworth and have three children.
Eric Brewton, who is currently in-house counsel at Travelers Insurance, will take Carl Bowers' spot in Division II of State Court.
Brewton, a former partner at the Marietta law firm of Brock, Clay, Calhoun and Rogers, earned his law degree at the University of Georgia. He lives in Marietta.
In June, the state's Judicial Nominating Commission named Green, Carl Bowers and Brewton to the short list of recommended candidates to replace Collins.
