An "arbitration hearing" can be either procedural or evidentiary. As in court systems, a "procedural hearing" focuses exclusively on how the proceedings are to be conducted. An "evidentiary hearing" is the equivalent to what in the courts of many countries would be called a trial, with the presentation of evidence in the form of documents and witnesses. Although evidentiary hearings are generally available as a means to assist the arbitral tribunal in deciding contested factual issues, arbitration rules do not usually require them and leave the means of decided disputed factual issues to the discretion of the tribunal. Many decisions of arbitral tribunals are made without any hearing at all.
