Shocking the Conscience of Humanity

The literature and jurisprudence of international criminal law relies on the claim that international crimes are exceptionally grave. DeGuzman looks to build the legitimacy of international law by exposing the value choices that the rhetoric of 'gravity' entails, and poses a new framework for assessing the legitimacy of international criminal law.

The most commonly cited justification for international criminal law is that it addresses crimes of such gravity that they "shock the conscience of humanity." From decisions about how to define crimes and when to exercise jurisdiction, to limitations on defences and sentencing determinations, gravity rhetoric permeates the discourse of international criminal law. Yet the concept of gravity has thus far remained highly undertheorized.

This book uncovers the consequences for the regime's legitimacy of its heavy reliance on the poorly understood idea of gravity. Margaret M. deGuzman argues that gravity's ambiguity may at times enable a thin consensus to emerge around decisions, such as the creation of an institution or the definition of a crime, but that, increasingly, it undermines efforts to build a strong and resilient global justice community. The book suggests ways to reconceptualize gravity in line with global values and goals to better support the long-term legitimacy of international criminal law.
