Since its codification almost fifty years ago, the law of treaties has laboured under the constant tension between the egoism of states and the increasing communitarian nature of contemporary multilateral treaties. Treaties that are crafted to protect human rights, preserve the environment or restrict state actions, such as in the use of chemical weapons, are indicative of this growing communitarian nature where collective action is necessary to achieve the overarching aim of the treaty. Debates about state consent and the extent to which a state has exercised its sovereign right to be bound under international law are the manifestations of this tension. The tension is borne of the allegiance of many scholars, and indeed states, to traditional characterisations of consent in international law and questions about the capacity of the 1969 Vienna Convention on the Law of Treaties (Vienna Convention) to guide modern international legal relations. To maintain the traditional model in the context of contemporary, communitarian oriented treaties, challenges to consent are often framed as lex specialis or the elucidation of ambiguous rules. A more nuanced approach to state consent and the application of the Vienna Convention rules supports the continued development of communitarian treaties while reinforcing the role of sovereignty in treaty-making.

In The Paradigm of State Consent in the Law of Treaties: Challenges and Perspectives, Vassilis Pergantis of the American College of Thessaloniki (ACT) and Aristotle University of Thessaloniki, Greece, sets out to contextualise this tension using four distinct aspects of treaty practice – construction of consent to be bound, withdrawal clauses, succession and reservations. Part I presents the theoretical framework for the study and defines the terms and limits of the case studies that make up Part II. Though the book is very much a work of legal analysis, Part I is reminiscent of Douglas Johnston's plea for a broader, cross-disciplinary evaluation of the traditional theory of international consent so as to avoid its “myth power” and enable a dispassionate enquiry that encompasses a range of approaches adopted from sociology, economics, political theory, etc, as much of the text is about the “socialised” development of the international community of states through treaty relations. Notably, the case studies generally rely upon multilateral treaties that pursue a common goal, such as the eradication of nuclear weapons...
