International law consists of rules and principles which govern the relations and dealings of nations with each other. International Law, which is in most other countries 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. In contrast, Private International Law deals with controversies between private persons, natural or juridical, arising out of situations having significant relationship to more than one nation. In recent years the line between public and private international law have became increasingly uncertain. Issues of private international law may also implicate issues of public international law, and many matters of private international law nave substantial significance for the international community of nations. International Law includes the basic, classic concepts of law in national legal systems – status, property, obligation, and tort (or delict). It also includes substantive law, procedure, process and remedies. International Law is rooted in acceptance by the nation-states which constitute the system. Customary law and Conventional law are primary sources of international law. Customary international law results when states follow certain practices generally and consistently out of a sense of legal obligation. Recently the customary law was codified in the ‘ ‘Vienna Convention on the Law of Treaties’. Conventional international law derives from international agreements and may take any form that the contracting parties agree upon. Agreements may be made in respect to any matter except to the extent that the agreement conflicts with the rules of international law incorporating basic standards of international conduct or the obligations of a member state under the ‘Charter of the United Nations’. .International agreements create law for the parties of the agreement. They may also lead to the creation of customary international law when they are intended for adherence generally and are in fact widely accepted. .
