In the practice of modern international law, disputes as to the meaning of specific treaty provisions are a frequent occurrence. It is the assumption underlying any such dispute that in a process of interpretation a distinction has to be made between the legally correct and incorrect interpretation result. The legal correctness of an interpretation result is determined by reference to the relevant international law, as reflected in the 1969 Vienna Convention on the Law of Treaties (VCLT), Articles 31-33. Hence, the regime laid down in VCLT Articles 31-33 will have to be described as a system of rules. This book investigates the contents and structure of this system. By importing knowledge from linguistics, and pragmatics in particular, a model is established giving representation to the concept of a rule of interpretation. Drawing on this model, the book then proceeds to reconstruct the contents of the various rules of interpretation.

This is the first comprehensive account of the modern international law of treaty interpretation expressed in 1969 Vienna Convention, Articles 31-33. As stated by the anonymous referee, it is the most theoretically advanced and analytically refined work yet accomplished on this topic. The style of writing is clear and concise, and the organisation of the book meets the demands of scholars and practitioners alike.
