"This Code is a privately developed set of standards of professional behavior for arbitrators who are subject to its provisions. It applies to voluntary arbitration of labor-management disputes and the other arbitration and related procedures [that] are described in the Preamble." (Taken directly from the Code) The code applies to the National Academy of Arbitrators, the American Arbitration Association and the Federal Mediation and Conciliation Service for arbitrators on their rosters in cases handled under their respective appointment or referral procedures. Other arbitrators and administrative agencies may voluntarily adopt the Code and be governed by it. In broad terms, the Code addresses: arbitrator's qualifications and responsibilities to the profession; responsibilities to the parties, including conflicts of interest, confidentiality, consent awards, and compensation; responsibilities to administrative agencies; and prehearing, hearing, and post hearing conduct, including impartiality, fairness, and award details.
