Arbitration, a form of alternative dispute resolution (ADR), is a legal technique for the resolution of disputes outside the courts, wherein the parties to a dispute refer it to one or more persons (the "arbitrators", "arbiters" or "arbitral tribunal"), by whose decision (the "award") they agree to be bound. It is a settlement technique in which a third party reviews the case and imposes a decision that is legally binding for both sides. Other forms of ADR include mediation (a form of settlement negotiation facilitated by a neutral third party) and non-binding resolution by experts. It is more helpful, however, simply to classify arbitration as a form of binding dispute resolution, equivalent to litigation in the courts, and entirely distinct from the other forms of dispute resolution, such as negotiation, mediation, or determinations by experts, which are usually non-binding. Arbitration is most commonly used for the resolution of commercial disputes, particularly in the context of international commercial transactions. It may be binding or non-binding.
