The initial aim of Public International Law has been to create an orderly system of international relations. However, the modern developments of this law have added another aim to it. Since the beginning of the Twentieth Century, there has been an evidence of a tendency to bring justice into the international community through ensuring justice in the relations of States and securing justice for peoples and individuals.
The establishments of the Permanent Court of International Justice in 1921 and the International Court of Justice in 1945 have been a clear evidence of such a new aim of the Public International Law. The use of the term “justice” in the name of these international courts where disputes among States are decided and where advisory opinions are given according to Public International Law is evidence that justice has become the concern of this law, and has become one of its aims and purposes.
To ensure and secure justice, and above all, to bring order to the international relations are the primary aims of the contemporary Public International Law. This law, which regulates relations between international persons, aims to create a system of order and justice for the international community. In the absence of such a system, it will be impossible for the international persons to have steady and continuous relations, and to enjoy the benefits of such relations.
