The subject matter addressed in this edited volume is timely as international and national courts increasingly apply international law... This book provides a rich and complex survey of how fragmentation in international law is being countered (or not) by international and national courts through a wide variety of ways and means. It is important to note that it reads more as a series of substantive case-studies than as a comprehensive analysis of fundamental normative questions – a point which the editors acknowledge. This is understandable given that further scholarship, especially on the normative and empirical aspects, on the role of international and national courts in relation to fragmentation needs to be undertaken, and I believe that this book has contributed in no small way toward that effort.

This new paperback aims to enhance our understanding of how international and national courts can, and do, contribute to or mitigate problems associated with fragmentation. The book contains case studies from international regimes (including the WTO, the IMF, investment arbitration and the ECtHR) and from various jurisdictions (including Japan, Norway, Switzerland and the UK). Essential reading for all those interested in the fragmentation of international law.
