International Law can be defined as the body of rules that nations recognize as binding upon one another in their mutual relations. Sources of international law include treaties, customs, general principles of law, resolutions and declarations of international organizations, equity, and writings of judges and legal scholars. International Law, which is also referred to as Public International Law, concerns itself only with questions of rights between several nations or nations and the citizens or subjects of other nations.
