Dr Oisin Suttle has a chapter in a new book just published by Oxford University Press. Exceptions in International Law, edited by Dr Lorand Bartels and Dr Federica Paddeu, provides a systematic and analytic study of exceptions to legal obligations in international law and defences for breaches of these obligations. It features contributions written by legal philosophers, who introduce various theoretical approaches to the role of exceptions, and scholars of international law, who elaborate on generic issues applicable to exceptions in international law, as well as examining specific issues arising from exceptions in their respective areas of expertise. Dr Suttle's chapter, "Reasons, Institutions, Authorities: Three Models of Exceptions in WTO Law", develops an account of exceptions as identifying the limits of the practical authority of laws and tribunals, and applies this to explain a number of specific exceptions in the law of the World Trade Organization.
