This challenging volume contains articles by a wide variety of well-known scholars and practitioners, and deals with human rights, international humanitarian law, international criminal law and humanitarian assistance, as well as other areas of international law relating to the protection of humanity. These are topics to which Flavia Lattanzi, in whose honour the volume is being published, has made an outstanding contribution and to which she has given her determined and unrelenting professional and personal commitment. As a former Professor at the Universities of Pisa, Sassari, Teramo and Roma Tre and as Judge ad litem at the International Tribunal for Rwanda and the International Tribunal for the Former Yugoslavia, she has adhered constantly to a number of important principles, as reflected in the research contained in this volume. They include the firm conviction that respect for human rights is an indispensable precondition for durable peace; the notion that grave breaches of human rights, including the refusal to provide assistance to populations in distress, can imply a threat to international peace and security; and that guarantees against human rights violations include the question of the punishment of core crimes under International Law.
