Non-State Actors and International Obligations examines the contribution and relevance of non-state actors in the creation and implementation of international obligations. These actors have traditionally been marginalised within international law and ambiguities remain over their precise role. Nonetheless, they have become increasingly important in legal regimes as participants in their implementation and enforcement, and as potential holders of duties themselves. Chapters from academics and practitioners investigate different aspects of this relationship, including the sources of obligations, their implementation, human rights aspects, dispute settlement, responsibility and legal accountability.
