Extraterritoriality is the state of being exempted from the jurisdiction of local law, usually as the result of diplomatic negotiations. Historically, this applied to individuals. Extraterritoriality can also be applied to physical places, such as foreign embassies, military bases of foreign countries, or offices of the United Nations. The three most common cases recognized today internationally relate to the persons and belongings of foreign heads of state, the persons and belongings of ambassadors and other diplomats, and ships in foreign waters.
