How is the port authority of New York and Jersey an example interstate compact?

The Port Authority of New York and New Jersey is an interstate compact between the U.S. states of New York and New Jersey. It was created in 1921 by an agreement between the two states, which was then ratified by the U.S. Congress. The Port Authority is responsible for developing and operating transportation and port facilities in the New York City metropolitan area. It owns and operates bridges, tunnels, airports, seaports, and other facilities, and it also provides a variety of services, including police, fire, and emergency medical services.

The Port Authority is an example of an interstate compact because it is a legally binding agreement between two states. The compact creates a separate legal entity, the Port Authority, which has its own powers and responsibilities. The Port Authority is not subject to the laws of either New York or New Jersey, and it is not subject to taxation by either state.

Interstate compacts are often used to create regional entities that can provide services that are beyond the scope of what individual states can provide. The Port Authority is a successful example of an interstate compact, and it has played a vital role in the development and operation of the New York City metropolitan area.
