A Massachusetts federal judge ruled that last year’s indictment of Milberg Weiss & Bershad and two of its lawyers and the firm’s conduct during a proposed securities class action case meant the firm was “not adequate” lead counsel.

In his Thursday order, Judge Joseph L. Tauro also denied class certification in the case against former executives and board members of Canton, Mass.-based skin substitute maker Organogenesis Inc. Organogenesis has since become a private company after investors bought it out of bankruptcy.
