The climactic event in international arbitration is usually a hearing, at which witnesses are questioned and arguments made. But, unlike in U.S.- or British-oriented court proceedings, where all evidence must be accepted and evaluated in a hearing before a court or a jury, in international arbitration, evidence may be made part of the record of the case from the first pleading, where documents and even written statements of witnesses may be presented. Subsequent submissions to the tribunal by the parties, often after exchanges of relevant documents between them, may provide the tribunal with additional documents.
