The Authority of International Law - A study in international legal positivism

This thesis analyses the authority of international law from the perspective of international legal positivism. The traditional approach that takes the state’s will as the foundation of international law is problematic as it results in the voluntarist dilemma. For international law to have objective power, a state should be incapable of escaping its authority by its own will even though this will is what constituted international law in the first place. The incompatibility of this would mean that international law’s authority is actually based on a ‘special’ will that is external to the wills of states. Georg Jellinek devised a theory of international law that supposedly accounts for international law’s objective authority while maintaining the state’s will as its foundation. His theory is built on what he calls “the normative force of the factual”, but falls short as it cannot withstand Hume’s law. Herbert Hart’s theory of law is more promising as it leaves the state’s will out of...Show moreThis thesis analyses the authority of international law from the perspective of international legal positivism.

His theory is built on what he calls “the normative force of the factual”, but falls short as it cannot withstand Hume’s law. Herbert Hart’s theory of law is more promising as it leaves the state’s will out of the equation and focuses on legal practice to understand the necessary features of a legal system. International law, however, is “law” but not a legal system. This thesis challenges Hart’s understanding of international law as “law” and argues that there is an international legal system consisting of primary and secondary rules.Show less
