Book excerpt: The question of whether non-state actors have human rights obligations is ultimately dependent on what we mean when we speak of human rights and what entities we consider to be non-state actors. Focusing the debate, this important collection presents an essential set of contributions which address these questions. An original introduction provides the context for the selection of papers that, first offer a general overview, and then a focus on the roles and impact of national legal orders, international organizations, corporations and rebel groups. This volume is essential reading for anyone interested in the fast-moving developments related to the ways human rights law now applies to non-state actors.
