This organization itself is actually a system that was created to ensure security and achieve permanent peace. International law, like domestic law, is not pre-arranged, the court cannot be binding, but the court has an essential role in ratifying laws, Therefore, the court derives the rule while not making a law. What was studied in this article is the breaking structure made by the court "in the case of military and paramilitary actions of the United States of America against Nicaragua".

The research method of this research is descriptive-analytical and library and internet sources were used to collect information.

In the case of Nicaragua, the court, in proving its opinion that the principle of prohibition of use of force and the principle of non-intervention are customary, cites and expresses several conventions. The 1944 Chicago Convention has emphasized the exclusive and complete sovereignty of a country over its airspace, and the 1958 Geneva Conventions on the Law of the Seas and the 1982 Monte Gobi Convention have also taken steps in this direction. Citing the above conventions, the court comes to the conclusion that "the provisions of the aforementioned conventions are merely a positive response to the established and previous principles of customary international law."
