A Louisiana judge on Tuesday ruled that Ralph Slaughter, a former president of the Southern University system, must repay $275,000 to the institution’s private fund-raising arm, according to The Advocate. The amount to be repaid includes a $200,000 salary supplement from the foundation that Mr. Slaughter received in 2009, shortly after the university’s Board of Supervisors voted not to renew his contract. The judge said Mr. Slaughter had violated his fiduciary responsibilities as a member of the foundation. In response, Mr. Slaughter said that the money he had received was agreed to in writing when he settled a whistle-blower lawsuit against the board, in 2007.
