The United States Arbitration Act (Pub.L. 68–401, 43 Stat. 883, enacted February 12, 1925, codified at 9 U.S.C. ch. 1), more commonly referred to as the Federal Arbitration Act or FAA, is an act of Congress that provides for judicial facilitation of private dispute resolution through arbitration. It applies in both state courts and federal courts, as was held in Southland Corp. v. Keating. It applies in all contracts, excluding contracts of seamen, railroad employees, or any other class of workers involved in foreign or interstate commerce, and it is predicated on an exercise of the Commerce Clause powers granted to Congress in the U.S. Constitution.
