The essays selected and reproduced in this volume explore how international refugee law is dynamic and constantly evolving. From an instrument designed to protect mostly those civilians fleeing the worse excesses of World War II, the 1951 Refugee Convention has developed into a set of principles, customary rules, and values that are now firmly embedded in the human rights framework, and are applicable to a far broader range of refugees. In addition, international refugee law has been affected by international humanitarian law and international criminal law (and vice versa). Thus, there is a reinforcing dynamic in the development of these complementary areas of law. At the same time, in recent decades states have shown a renewed interest in managing migration, thereby raising issues of how to reconcile such interests with refugee protection principles. In addition, the emergence of concepts of participation and responsibility to protect promise to have an impact on international refugee law.
