In a 4-2 decision Friday, the high court concluded Denise Majette violated the Rules of Professional Conduct.
The majority opinion said Majette submitted unsupported and misleading timesheets and invoices to a client and misrepresented her hours and fees to a court. Majette did not immediately respond to a call seeking comment.
Majette was admitted to the State Bar of Georgia in 1983. In the dissenting opinion, Justice Harold Melton argued Majette had had no other disciplinary problems. He wrote a more appropriate punishment would be a prolonged suspension with conditions for reinstatement.
Majette was elected to Congress in 2002 but left two years later to run for U.S. Senate.
