Parties seeking to settle a dispute by means of arbitration can turn to the Permanent Court of Arbitration. Most disputes submitted to the PCA involve at least one state, but may also involve international organizations, corporations, or individuals. In most cases a three-member tribunal is constituted with each party appointing one arbitrator, who together appoint a president. The Court thus formed decides the case. Together the parties also establish the legal question to be decided, the language to be used, and the degree of confidentiality. The decision of the arbitrators is binding in all cases on the parties. The PCA also offers non-binding forms of dispute settlement, such as mediation and fact-finding commissions of inquiry.
