Book excerpt: Harmonised and uniform international laws are now being spread across different jurisdictions and fields of law, bringing with them an increasing body of scholarship on practical problems and theoretical dimensions. This comprehensive and insightful book focuses on the contributions to the development and understanding of the critical theory of harmonisation. The contributing authors address a variety of different subjects concerned with harmonisation and the application of legal rules resulting from harmonisation efforts. This study is written by leading scholars engaged in different aspects of harmonisation, and covers both regional harmonisation within the EU and regional human rights treaties, as well as harmonisation with international treaty obligations. With comparative analysis that contributes to the development of a more general theory on the harmonisation process, this timely book will appeal to EU and international law scholars and practitioners, as well as those looking to future legal harmonisation in other regions in Asia, Latin America and Africa.
