A Lithonia attorney disbarred by the Supreme Court of Georgia Monday has had a career marred by controversy, including his ouster from a judgeship and an international indictment.

The state high court disbarred Melvin T. Johnson of the Action Johnson Firm based on “serious misconduct” in five client matters and multiple violations of the State Bar of Georgia’s ethics rules. The high court also said Johnson “has shown contempt for the disciplinary process” by refusing to respond to bar investigators’ requests for information or to their motions, including a move to sanction him.
