OUVRAGE : J. Christófolo, Solving Antinomies between Peremptory Norms in Public International Law

João Ernesto CHRISTÓFOLO

Ius cogens has been a subject of great interest in international law studies. But the inquiry into the collision between peremptory norms has been virtually non-existent. This book aims at addressing this particular doctrinal gap. Antinomies between ius cogens norms may arise in the conflicting simultaneous application of the peremptory norms on human rights, the non-use of force and self-determination. In order to determine how norms of ius cogens might be applied in situations of normative conflict - either apparent or real ones -, the author suggests the use of “weighing and balancing” techniques. After analysing the main theories on the issue, and describing the most commonly accepted peremptory norms in current international law, this work approaches the problem of antinomies between peremptory norms by applying “weighing and balancing” techniques to two case studies.
