This book analyses, comments and further develops on the most important instrument of the Hague Conference on Private International Law (HCCH): the HCCH 2019 Judgments Convention. The HCCH Convention, the product of decades of work, will have a transformative effect on global judicial cooperation in civil matters. This book explores its ‘mechanics’, i.e. the legal cornerstones of the new Convention (Part I), its prospects in leading regions of the world (Part II), and offers an overview and comment on its outlook (Part III). Drawing on contributions from world-leading experts, this magisterial and ambitious work will become the reference work for law-makers, judges, lawyers and scholars in the field of private international law.
