This is a report of the evaluation of three federal mandatory arbitration programs, which were piloted in the Eastern District of Pennsylvania, the Northern District of California, and the District of Connecticut. The information was compiled by distributing questionnaires to counsel in arbitration and litigation cases; researching court dockets for the above-mentioned cases and for similar cases filed during the three years prior to the dates the arbitration rules took effect; distributing questionnaires to arbitrators; interviewing arbitrators, counsel, and court personnel; and analyzing statistics kept by the Administrative Office of the U.S. Courts. In general terms, the findings indicate that arbitration expedites the disposition of cases, counsel and litigants are satisfied with the process and outcomes, and that it is unclear whether arbitration reduces the overall cost of litigation to the litigants and the judiciary.
