Established in 2021, the TRICI-Law Book Series is a limited series that aims to publish monographs and edited volumes on topics that shed light on legal interpretation in international law, with a particular emphasis on the interpretation of customary international law. Titles appearing in the series examine the interpretation of customary international law from a theoretical and practical perspective, and compare the characteristics of legal interpretation in international law across courts, regimes and sources as they have evolved and continue to do so through time. The TRICI-Law Book Series is a joint initiative between Cambridge University Press, the European Research Council and the University of Groningen.

The titles in this series are available as Open Access thanks to the generous funding from the European Research Council (ERC) under the European Union’s Horizon 2020 Research and Innovation Programme (Grant Agreement No 759728) and the University of Groningen.
