The Principle Pacta Sunt Servanda and the Nature of Obligation Under International Law
Published online by Cambridge University Press: 27 February 2017
Extract
The principle that treaty obligations must be fulfilled in good faith is one aspect of the fundamental rule that requires all subjects of international law to exercise in good faith their rights and duties under that law.
In the sociopolitical sphere, this fundamental principle may be seen as manifesting the need perceived by states for an international legal system that can ensure international order and prevent arbitrary behavior and chaos. In the legal sphere, the principle is confirmation of the character of international law as law. Subjects of international law are legally bound under the principle to implement what the law prescribes.
