Public International Law

What is Public International Law?

International Law Commission

Public international law is chiefly concerned with the relationships between national governments and intergovernmental organizations.  It has no formal constitutional structure, no central organization, and no centralized law making authority. This has significant consequences for research, because the absence of an overall law-creating body means that international law must be identified through a wide variety of sources. (photo credit))
