Public international law

Definition and stakes

Jay William Hudson A Practical International Program (1915)

There must be some way of compelling defiant nations to observe the world order. Now, just what this means of compulsion shall be is a question of no little debate. Many have thought that all that the international law and the international court will need is the sanction of the public opinion of each nation added to the sanction of that ever growing and powerful unit, international public opinion. No doubt public opinion is a most important factor in securing obedience to law. No doubt any law would be utterly useless unless public opinion were behind it demanding its enforcement.

L. Oppenheim International Law. A Treatise. Volume 1…

The heads of the civilised States, their Governments, their Parliaments, and public opinion of the whole of civilised humanity, agree and consent that the body of rules of international conduct which is called the Law of Nations shall be enforced by external power, in contradistinction to rules of international morality and courtesy, which are left to the consideration of the conscience of nations.
