The arbitrators which determine the outcome of the dispute are called the arbitral tribunal. Many decisions of arbitral tribunals are made without any hearing at all. Those clauses generally empower the party "commencing" the arbitration to select the arbitral institution. In addition, an organisation of arbitral courts was set up to decide all disputes. Moreover, arbitral awards prove frequently easier to enforce than court decisions from overseas. The organisation governs the arbitral process through a set of rules and administrative structures. Only domestic arbitral awards are subject to set aside procedure. The Convention provides a simple, uniform and effective means of enforcing arbitral awards and processes. A number of arbitral institutions have adopted the UNCITRAL Rules for use in international cases. The Venezuelan government showed almost immediate disapproval with the 1899 Arbitral Award.
