Abstract

This is the first definitive monograph on the concept of obligations erga omnes---international obligations owed to the international community as a whole and binding irrespective of consent---an increasingly important concept in contemporary international law. Ragazzi adopts a pragmatic approach that identifies five common elements among the examples of obligations erga omnes given by the International Court. These five common elements are then discussed in the light of other candidates of obligations erga omnes which have emerged in State practice and international literature.
