Lawyers representing former Dewey & LeBoeuf executive director Stephen DiCarmine and former chief financial officer Joel Sanders filed fresh briefs Friday asking a Manhattan state court judge to drop criminal charges against the defendants.

DiCarmine and Sanders are scheduled to face a retrial later this year, after their prosecution led to a mistrial in October. Along with former Dewey chairman Steven Davis, the former executives were accused of orchestrating a scheme to steal from the law firm’s investors in the follow-up to its 2012 collapse and bankruptcy.
