A key witness in the criminal retrial over the collapse of Dewey & LeBoeuf told a Manhattan jury on Friday that he never discussed improper accounting adjustments with former Dewey executive director Stephen DiCarmine.

In his fifth day on the stand, former Dewey finance director Francis Canellas, a cooperating witness in the Manhattan District Attorney’s case against DiCarmine and former Dewey CFO Joel Sanders, fielded a string of questions about the two executives’ work at the firm.
