Whilst the concept of jus cogens has grown increasingly more important in public international law, lawyers remain hugely divided both over what precisely confers a jus cogens status on a norm, and what this conferral implies in terms of legal consequences. In this ground-breaking book, Ulf Linderfalk clearly and succinctly explores the reasons for this divide in order to facilitate more rational and productive future discourse.

This book offers a comprehensive analysis of the law of treaties based on the interplay between the 1969 Vienna Convention on the Law of Treaties and customary international law. Written by a team of renowned international lawyers, it offers new insight into the basic concepts and methodology of the law of treaties and its problems.

Because of its unique nature, the sources of international law are not always easy to identify and interpret. This book provides an ideal introduction to these sources for anyone needing to better understand where international law comes from. As well as looking at treaties and custom, the book will look at more modern and controversial sources.

This work explores in depth the legal consequences of peremptory norms.

Winner of the 2020 ASIL Lieber prize! In Peremptory Norms of International Law and Terrorism (Jus Cogens) and the Prohibition of Terrorism, Aniel de Beer analyses the role of these norms (jus cogens norms) in the fight against terrorism. Jus cogens norms protect fundamental values of the international community, are hierarchically superior and non-derogable. The author argues, based on an analysis of the sources of international law, that the prohibition of terrorism has become the jus cogens norm of our time. She further considers the impact of the status of the prohibition of terrorism as a jus cogens norm on other norms of international law relevant in the fight against terrorism, namely the prohibition of torture, the right to a fair trial and the prohibition of the inter-state use of force.
