customary international law
Customary international law refers to practices and norms that countries consistently follow and accept as legally binding, even if they are not written in treaties. These unwritten rules develop over time through widespread and consistent state behavior, accompanied by a belief that such behavior is legally required. Examples include diplomatic immunity and the prohibition of torture. Customary international law helps maintain order and predictability in international relations, providing a framework for how states interact with one another based on established customs rather than formal agreements.

Customary International Law refers to practices and norms that countries follow because they believe it is legally binding, not because of written laws or treaties. These customs develop over time through consistent and accepted behavior among nations, reflecting their shared values and expectations. For instance, humanitarian principles during armed conflict have become customary law. Although not formally codified, these unwritten rules are considered binding on states and play a crucial role in international relations, influencing how countries interact, resolve disputes, and uphold human rights globally.
