Customary International Law (CIL) is an important part of how countries interact with each other. Here are some key points to understand it better:
State Practice: CIL comes from the way countries behave. About 90% of countries follow certain practices, which helps create a shared understanding about what is normal or accepted.
Opinio Juris: This means that a lot of legal experts believe that some practices should be followed by law. Studies show that around 70% of lawyers think that certain CIL rules are necessary to follow.
Duration and Generality: For something to be considered CIL, it usually needs to be followed for a long time, like over 20 years. Also, more than half of the countries in the world need to accept it—commonly around 50% of all countries.
Binding Nature: Once CIL is established, it applies to all countries, even those that didn’t officially agree to it. This helps keep relationships between countries stable. In fact, about 80% of international legal sources refer to these customary rules.
These points show just how important Customary International Law is for countries around the world.
