Understanding Customary International Law: Definition and Key Principles

Definition & Meaning

Customary international law is a type of law that becomes binding on nations when they generally accept it as a legal obligation. This law arises from consistent practices that states adopt over time, reflecting their belief that such practices are legally required. It is considered a primary source of international law by institutions like the International Court of Justice and the United Nations. An example of customary international law is the laws of war outlined in the Geneva Conventions.
