A former Member of Congress was disbarred by the Georgia Supreme Court for billing fraud:

The facts, as found by the special master and Review Panel, and supported by the evidence, show that Majette, who was admitted to the Bar in 1983 and had a distinguished career, was having financial difficulties in 2008 while working part-time as a lawyer and part-time as a real estate agent. As a result, she sought a loan from a lawyer with whom she was acquainted. The lawyer declined to loan Majette money, but offered to associate her in a litigation matter in which the lawyer and an associate represented two clients in litigation involving a trust of which the clients were beneficiaries. Majette accepted the offer; the lead lawyer and Majette agreed that Majette’s fee would be $200 per hour. The lawyer paid Majette $2,000 as a retainer on September 2, 2009, and additional sums totaling $22,500 through March 2010. The lawyer considered these sums to be an advance to be applied against fees earned. Majette did not keep contemporaneous time records, but reconstructed her time sheets and invoices from memory and from notes on her calendar or computer.

Justice Melton, joined by Chief Justice Thompson, dissented as to sanction

While I agree that the conduct involved in this case merits a severe punishment, I believe that a prolonged suspension with conditions for reinstatement, rather than disbarment, would be a more appropriate sanction. As the Review Panel concluded in this case, the respondent’s over thirty years of distinguished service to the bench and bar with no disciplinary problems whatsoever should serve as a significant mitigating factor with respect to the punishment imposed here.
