Principle of Nonintervention Law and Legal Definition

Principle of nonintervention as used in International law refers to a rule that a country should not interfere in the internal affairs of another country. The rule is based upon the principles of state sovereignty and self-determination. This principle is also embodied in Article 2(7) of the U.N. Charter which binds it from intervening “in matters which are essentially within the domestic jurisdiction of any state.”
