Conferment & determination of jurisdiction

HOW CONFERRED? Jurisdiction is conferred by the law in force at the time of its institution.

HOW DETERMINED? Jurisdiction is determined by the allegations of the complaint and the character of the relief sought.

However, in order to determine which court has jurisdiction over the action, an examination of the complaint is essential. Basic as a hornbook principle is that jurisdiction over the subject matter of a case is conferred by law and determined by the allegations in the complaint which comprise a concise statement of the ultimate facts constituting the plaintiff's cause of action. The nature of an action, as well as which court or body has jurisdiction over it, is determined based on the allegations contained in the complaint of the plaintiff, irrespective of whether or not the plaintiff is entitled to recover upon all or some of the claims asserted therein. The averments in the complaint and the character of the relief sought are the ones to be consulted. Once vested by the allegations in the complaint, jurisdiction also remains vested irrespective of whether or not the plaintiff is entitled to recover upon all or some of the claims asserted therein.
