Resumen de Is Treaty interpretation an Art or a Science? International Law and rational decision making
Although treaty interpretation is undoubtedly an activity governed by international law, and by Articles 31-33 of the 1969 Vienna Convention on the Law of Treaties (VCLT) in particular, some commentators continue repeating the pre-Vienna adage that treaty interpretation is a matter of art and not science, the implication of which is that no understanding of a treaty provision can ever be explained rationally. As the present article argues, this idea of interpretation must be rejected. While, sometimes, an assumed meaning of a treaty cannot be justified based on international law simpliciter, many times it can still be explained based on the structural framework of Articles 31-33 of the VCLT. Consequently, any characterization of treaty interpretation in the abstract as either art or science is misplaced. Whether treaty interpretation is an art or a science remains a question of fact inextricably tied to the approach taken by each and every law-applying agent in particular cases.
