Public International Law

What is public international law?

Public International Law is composed of the laws, rules, and principles of general application that deal with the conduct of nation states and international organisations among themselves as well as the relationships between nation states and international organisations with persons, whether natural or juridical. Public International Law is sometimes called the "law of nations" or just simply International Law. It should not be confused with Private International Law, which is primarily concerned with the resolution of conflict of national laws, determining the law of which country is applicable to specific situations.
