The Supreme Court consists of a President and at minimum 15, currently 18, other Justices, usually working in five-judge panels. The most important function of the Supreme Court is to rule on important points of law in cases which are significant for the entire legal order, guiding the administering of justice in future cases. Decisions of the Courts of Appeal (, ), as well as certain decisions of the Insurance Court may be appealed against to the Supreme Court, provided that it grants leave to appeal. In the rare criminal cases where a Court of Appeal acts as the court of first instance, the leave to appeal is not needed. (Cases of espionage, treason and criminal cases involving high civil servants or officers of at least major's rank fall into this category.)
