The traditionally top-down focus in human rights scholarship on laws, institutions, and courts has begun to turn towards a bottom-up focus on activists, advocacy groups, affected communities, and social movements. The essays collected in Legal Mobilization for Human Rights examine a range of issues including which groups claim rights, what they are mobilizing to protect, the goals they pursue, the forums they use, the obstacles they encounter, and the extent of their success or failure. Case studies reveal key themes such as: the importance of human rights to marginalized communities; how political and societal authoritarianism shapes opportunities for effective mobilization; the importance of the choice of forum for instigating change; the role intermediary actors such as NGOs play in innovating strategies to address challenges; the possibilities for subaltern mobilization to reshape human rights law; and the importance of supporting genuinely community-led legal mobilization.
