Non-governmental organizations (NGOs) play an increasing political role on the international scene, and their position in relation to international law is generally regarded as important but informal. Their actual legal status has not been the subject of much investigation. This book examines the legal status of NGOs in different fields of international law, with emphasis on human rights law. The rights, obligations, locus standi and consultative status of NGOs are explored by means of a thorough examination of international legal rules and practices. .
