In recent years, justice-related issues have figured prominently on the international agenda. This expansion of the justice space is a product of a growing demand for accountability in world politics. Whether the issue is addressing heinous crimes such as genocide, war crimes and crimes against humanity in situations of armed conflict, confronting the inability or reluctance of governments to protect their own populations, or responding to the challenges posed by transnational terrorism, the international community has witnessed the proliferation of institutions and mechanisms, as well as the dynamic interplay between domestic and international processes, in the pursuit of justice-sensitive outcomes. International and hybrid tribunals, UN-led and domestic counter-terrorist initiatives, and the use of force for human protection purposes have demarcated the space within which ethical, political, and legal debates have unfolded in the quest for a more humane world order.
