Labaton Sucharow has moved for a federal judge reviewing its billing records to recuse himself from a securities class action settlement, citing a “serious conflict” raised by statements from the judge, which the firm said implied that the New York law firm was engaged in public corruption.

According to the motion, remarks made by U.S. District Judge Mark Wolf of the District of Massachusetts at a May 30 hearing raised “a legitimate concern as to whether Labaton will receive a truly impartial review.”
