​KembaraXtra – Legal Terms – Publicist


A publicist in international law refers to a legal scholar or scholarly organization whose writings may assist in determining the rules of international law. Under Article 38 of the Statute of the International Court of Justice, the teachings of highly qualified publicists are recognized as subsidiary sources of international law. Their opinions are not binding law but may strongly influence judicial reasoning and the development of legal principles. Publicists often analyse treaties, state practice, and judicial decisions to clarify uncertain areas of international law.


Historically, influential publicists included figures such as Hugo Grotius, often described as the father of international law, as well as Van Bynkershoek, Pufendorf, and Vattel. In more modern times, the International Court of Justice has frequently referred to writers such as Sir Hersch Lauterpacht, Shabtai Rosenne, and Sir Gerald Fitzmaurice. Scholarly organizations like the Institut de Droit International also contribute significantly to the development of legal doctrine. Publicists therefore help shape and explain international legal norms even though they do not themselves create binding law.
