In Status of NGOs in International Humanitarian Law, Claudie Barrat examines the legal framework applicable to NGOs in situations of armed conflict. The author convincingly demonstrates, contrary to convention, that in addition to the ICRC, the National Societies and the IFRC, numerous other NGOs referenced in humanitarian law treaties have a legal status in IHL and therefore legitimate claim to employ IHL provisions to respond to current challenges. On the basis of clear and thorough definitions of these entities, Barrat argues that existing NGOs meeting stringent definition can benefit from customary rights and obligations in both international and non-international armed conflict.
