Article 3 - State Responsibilty
Article 3. This article is about the Characterisation of an act of a State as Internationally wrongful. A local law that results into violation of an international law is not an excuse to permit such a breach of international law. In other words a state cannot hide behind the excuse that its national law is in violation of an international obligation because it is the responsibility of the states to comply with their international obligations. Once a state becomes a part of an international law then it is under an obligation to revise any such local laws which may or are in contravention to the International law. Therefore if a state fails to revise all such laws then it shall be responsible under International law.
