Arbitration is a legal technique of resolving disputes outside the courts, whereby parties involved in the dispute refer it to an arbitrator (the "arbitrators", "arbiters" or "arbitral tribunal") or arbitrators( one or more persons) , by whose decision (the "award") they may be bound(as in mandatory arbitration) or not(as in voluntary or nonbinding arbitration).
The above methods of arbitration :peer review, arbitration, mediation all allow the dispute parties' input before arbitration decision. Peer review method involves dispute resolution in the workplace whereby employees are able to take disputes to fellow employees and managers to act as arbitrator to resolve disputes which may not be binding on the parties. Mediation on another hand is a dynamic method of dispute resolution where a third party helps to resolve disputes by helping dispute parties negotiate to resolve to dispute. Arbitration however differs from mediation in that the arbitrator makes decisions based on evidence presented and not waiting to negotiate an agreement between both parties. All three methods however require dispute parties to make inputs so as to arrive on final decision.
