There is very little meaningful appeal or review. In some circuits, you can appeal from a manifest disregard of the law, in others you can not. Limited discovery and proceedings. The procedure is restrictive in order to reduce costs. Absence of evidentiary rules.
Most arbitrators allow virtually everything into evidence.
Is Not Ground For Reversal Siegel v. Siegel took his wrongful discharge claim to arbitration under the rules of the National Association of Securities Dealers. These results themselves are curious in light of the fact that the FAA does not state this as a ground for vacating an award. This judicially-created standard might be precarious because of its lack of statutory foundation. An arbitration clause in a contract shipped with a mail-order computer is valid, but the requirement that buyers arbitrate disputes with the seller under the rules of the International Chamber of Commerce is unenforceable because such proceedings are too expensive for most consumers.
