Criminal antitrust trials occur relatively infrequently these days, so an occasional review of some of the issues that arise at trial can be useful as a refresher. Many government witnesses at a criminal antitrust trial are testifying pursuant to some type of agreement with the government. Such agreements include amnesty, immunity, non-prosecution/cooperation agreements and plea agreements. The essence of the agreement is that the witness will receive some type of benefit in the form of a reduced punishment (or immunity). In return, the witness agrees to cooperate with the government and testify at trial. If the witness does not give truthful testimony, he/she is theoretically subject to prosecution for perjury, and may also lose the benefits conferred by the agreement
A recent Second Circuit decision, U.S. v. Certified Environmental Services, Inc., No. 11-4872 (2d Cir. May 28, 2014), provides a chance to review the proper use of plea agreements at trial. The court reversed convictions on several counts related to a scheme by defendants to violate various state and federal environmental regulations. The convictions were reversed based, in part, on the government having improperly bolstered the witness’s credibility by referring to the cooperation agreement requirement that the witness tell the truth.
