The Court decides cases upon the record of the proceedings before the lower court and after considering the written and oral arguments presented. Witnesses do not appear before the court, and the parties need not be present during the hearing of an appeal. A written judgment is usually handed down shortly after the argument.
The Court hears appeals on fact and since there are no jury trials, it has a relatively wide discretion to make its own factual findings. Because of this jurisdiction, judges have to read the record of the full proceedings in the lower courts. Typically, each judge is allocated cases with about 30 000 pages of evidence and exhibits per year. In addition, each judge is allocated petitions for leave to appeal.
