The mission of the The Italian Yearbook of International Law is to make available to the English speaking public the Italian contribution to the literature and practice of international law. It is fitting with this mission that this Volume XXIV opens with a focus on the controversial Judgment No. 238/2014 of the Italian Constitutional Court on the unconstitutionality of State immunity for international crimes. The five contributions by Francioni, Pisillo Mazzeschi, Bothe, Cataldi, and Palchetti provide a variety of opinions on the timely issue of how traditional doctrines of State immunity may be reconciled with the need to protect victims of international crimes and what kind of alternative forms of protection may be available when immunity prevents access to judicial remedies.
