The tract of land or district within which a judge or magistrate has jurisdiction, is called his territory and his power in relation to his territory is called his territorial jurisdiction. Every act of jurisdiction exercised by a judge without his territory, either by pronouncing sentence or carrying it into execution, is null. An inferior court has no jurisdiction beyond what is expressly delegated. Some courts and magistrates have both civil and criminal jurisdiction.
Jurisdiction is also concurrent, exclusive or assistant.
Concurrent jurisdiction is that which may be entertained by several courts. It is a rule that in cases of concurrent jurisdictions, that which is first seized of the case shall try it to the exclusion of the other. Exclusive jurisdiction is that which has alone the power to try or determine the Suit, action or matter in dispute. But where the court has jurisdiction of the matter and the defendant has some privilege which exempts him from the jurisdiction, he may wave the privilege. Courts of inferior jurisdiction must act within their jurisdiction and so it must appear upon the record.
