 The U.S. Supreme Court has held that the Federal Arbitration Act (FAA) of 1925 established a public policy in favor of arbitration.For the first six decades of its existence, courts did not allow arbitration for "federal statutory claims" through a bright-line "nonarbitrability" doctrine, but in the 1980s the Supreme Court of the United States reversed and began to use the act to require arbitration if included in the contract for federal statutory claims.Although some legal scholars believe that it was originally intended to apply to federal courts only, courts now routinely require arbitration due to the FAA regardless of state statutes or public policy unconscionability determinations by state courts.
