Territorial jurisdiction refers to the legal authority of a court or government to make decisions and enforce laws within a specific geographic area. This concept is essential in determining which laws apply and which courts have the power to hear cases. For example, a crime committed in New York falls under the territorial jurisdiction of New York courts. Different regions may have varying laws, so understanding territorial jurisdiction helps clarify where legal matters should be addressed. It ensures that individuals and entities are subject to the laws of the area in which they operate, promoting order and accountability within that territory.
