Customary International Law

Customary international law is another important source of legal norms in the international arena. Unlike treaties, customary international law is not based on written agreements but rather on consistent state practice and opinio juris (a belief that a particular practice is legally required). This means that certain norms and principles become binding on states through a long-standing and widely accepted practice. For example, the prohibition of genocide and the principle of diplomatic immunity are considered customary international law.

General Principles of Law

The General Principles of Law, recognized civilized nations, another foundational source international law. These principles are derived from the legal systems of states and serve as guiding norms for international legal practice. For example, the principle of pacta sunt servanda (agreements must be kept) is a general principle of law that underpins the enforcement of treaties in international relations.

Judicial Decisions and Scholarly Works also contribute development international law. The decisions of international courts and tribunals, such as the International Court of Justice, provide authoritative interpretations of legal principles and help to shape the evolution of international law. Additionally, academic writings and scholarly analyses contribute to the understanding and development of international legal norms.
