Sufficient Gravity before the International Criminal Court is poised to become a seminal text in the field, offering definitive guidance on a concept that lies at the heart of international criminal accountability. -- Leila Sadat, Washington University School of Law, USA The task of elucidating the mysteries of gravity falls to scholars in the discipline. Marco Longobardos meticulously researched study, combined with his thoughtful analysis rooted in public international law principles, constitutes an immense contribution in this area. -- From the Foreword by William Schabas, Middlesex University London, UK Gravity is an important, yet elusive component in the process of deciding whether a case is admissible before the ICC. With his usual acumen, Marco Longobardo demonstrates in this book that the concept has more legal weight than meets the eye: a must-read for both academics and practitioners. -- Harmen van der Wilt, University of Amsterdam, the Netherlands This is an ultimate book on sufficient gravity. It fills the gap on one of the most fundamental but insufficiently researched areas of international criminal law. In a very erudite way, the author explains the notion of sufficient gravity in theory and practice. The book will be of interest to all international lawyers as it is firmly entrenched in general international law, such as the treaty interpretation. The monograph presents as well a wide historical background in the application of sufficient gravity. The monograph is an exceptional intellectual achievement. -- Malgosia Fitzmaurice, Queen Mary University of London, UK International law abounds with elusive concepts, whose vagueness is often open to strategic exploitation. By applying a rigorous forensic lens to the notion of sufficient gravity under the Rome Statute, Longobardo makes a vital contribution to the coherence of ICC practice and to the principled avoidance of double standards. -- Philippa Webb, University of Oxford, UK
