Arbitrator Immunity From Suit and Testimony Annotated Research Guide and Bibliographies


The vast bulk of parties to arbitration proceedings recognize that arbitrators have a limited role in their dispute which ends with the issuance of the Decision and Award. However, some parties have filed suits against arbitrators or attempted to compel arbitrators to provide evidence in post-decision actions. The experience of the National Academy of Arbitrators has been that many of these actions come from individual grievants, with or without counsel, after losing in arbitration. Most involve subpoenas and/or requests to appear for depositions.


Courts in most jurisdictions have held that arbitrators are immune from suit regarding their actions while in the capacity of an arbitrator. Sponsoring organizations (e.g., AAA and NASD) share this immunity. A few states have enacted statutes specifically providing immunity; absent statute, courts have found common law immunity. Courts have also held that arbitrators cannot be compelled to provide evidence related to an arbitration proceeding after rendering an arbitration award, either directly through testimony or affidavit, or indirectly by a subpoena of their notes.


Arbitrators from all geographic areas, with all degrees of fame and years in practice, have been the subject of requests for their testimony and notes, as well as lawsuits naming them as defendants. Most such cases are resolved without protracted litigation or great cost. Often, they are withdrawn once the relevant case law has been cited. The law of arbitrator immunity is well settled, fake watches but not necessarily well known. Arbitrators who have been served with a subpoena, deposition request, or lawsuit may want to read the following materials and cases and provide them to their attorneys. Most of them come from a compilation of authority prepared by Barry Winograd, who was the 1997-98 Chair of the National Academy of Arbitrators Committee on Legal Representation.
