Abstract
“ Subsidiarity ” views of crime against humanity propose that state crime is at the core of the idea, thus necessitating a further level of authority. That proposal can be given a strong moral justification in terms of the enormous risks that arise from a state’s authority and territorial control. Discussions of crime against humanity by Larry May and Norman Geras, however, offer different views of the idea, May proposing that it be seen as group-based crime, Geras proposing that it be seen as a serious violation of human rights. Those views are questioned on the basis of their fit with either the nature of the crimes involved or the moral basis of their condemnation, and the subsidiarity view is restated
