The jurisdictional function is the essential attribute of judicial authority. It consists in the act by which the judge discovers, on the occasion of a dispute, which rule of law (abstract and impersonal) finds to apply in the concrete circumstances of the case submitted to him. Literally, juris-dictio consists in the act of stating the law.
The function of the jurisdiction is to state the law, however all the acts of the judge are not the expression of his jurisdictional power. A distinction must be made between strictly judicial decisions (orders, judgments and rulings) and other types of decisions (administrative or disciplinary).
