Abstract
International commercial arbitration and national commercial arbitration are issues of international private law combined with global and local aspects. The rules of the procedure in international commercial arbitration vary around the world and are combined with the very strong influence of national law and are determinate by the place where the arbitration procedure is being preceded by the arbitrators. Obtaining evidence in commercial arbitration is also dependent on the above-mentioned aspects. The arbitrators have to know, as much as possible, all about the common law system, the civil law system’s influence and the powers and initiation possibilities they have during the arbitration procedure. The knowledge of the system and existing procedure rules allow them to produce the most important part of the arbitration, such as a perfect award.
