Arbitration is a formal method of dispute resolution involving a third party neutral who makes a binding decision. The neutral third party (the 'arbitrator', 'arbiter' or 'arbitral tribunal') renders the decision in the form of an 'arbitration award'. An arbitration award is legally binding on both sides and enforceable in local courts, unless all parties stipulate that the arbitration process and decision are non-binding.
Arbitration is often used for the resolution of commercial disputes, particularly in the context of international commercial transactions. In certain countries, such as the United States, arbitration is also frequently employed in consumer and employment matters, where arbitration may be mandated by the terms of employment or commercial contracts and may include a waiver of the right to bring a class action claim. Mandatory consumer and employment arbitration should be distinguished from consensual arbitration, particularly commercial arbitration.
