What is the territory, subject matter, or people over which a court or other justice agency may exercise lawful authority, as determined by statute or constitution?

Jurisdiction

Explanation:

Jurisdiction is the territory over which authority is granted by law to the courts to exercise lawful authority or rule on legal matters and render judgments, according to the subject matter of the case, and the geographical region in which the issue took place. A formally authorized legal body is a court, political or governmental office, and in many situations, law enforcement agency. When a legal body holds jurisdiction, it has the authority to administer justice within that jurisdiction.
