Chief Judge Mark Wolf of the District of Massachusetts ruled not to sanction Assistant U.S. Attorney Suzanne Sullivan for failing to disclose exculpatory evidence in a timely fashion despite his doubts that new government discovery training programs for prosecutors would succeed.

Wolf’s Friday, 23-page order in U.S. v. Jones explained his reasoning, and his reservations, about not imposing sanctions on Sullivan or the U.S. Attorney’s Office for the District of Massachusetts for Sullivan’s prosecutorial misconduct.
