In re Friedman
Supreme Court of Illinois
392 N.E.2d 1333 (1979)
Friedman, chief of the Cook County State's Attorney's office, directed officers to give false testimony and persuaded witnesses to stay away from court in order to convince defense attorneys his office was cooperating with bribery schemes, later having the same officers formally disclose their perjury and its circumstances to the court once each staged bribery transaction was completed; a disciplinary hearing board initially found no rule violations, but the review board found violations and recommended censure, and Friedman appealed to the Illinois Supreme Court.
Whether a prosecutor's intentional presentation of false evidence violates the Code of Professional Responsibility when the prosecutor's motive is to develop evidence in support of a subsequent prosecution.
