A Chinese businessman accused a former high-ranking administrative law judge of committing legal malpractice Monday in the opening statements of a bench trial at the U.S. District Court for the District of Columbia.

Kevin So, a cosmetics manufacturer from Hong Kong, hired D.C. solo practitioner Leonard Suchanek in July 2006 to represent him in July 2006 after he was victimized in an international Ponzi scheme. Suchanek, who retired as chief judge of the General Services Administration’s Board of Contract Appeals in 1992, allegedly failed to inform So of several conflicts of interest. So ultimately lost the suit, and he is now seeking more than $3 million in legal fees and expenses. The trial began Dec. 7 before Senior Judge James Robertson.
