Over the past decades, Colombian society has endured the impact of a longstanding political conflict among different actors and outrageous expressions of violence, especially among left-wing guerrillas, right-wing paramilitary groups and the state government. Drawing on socio-legal studies in transitional justice and human rights, this research attempts to analyze the recent experience of transitional justice in Colombia. The main purpose of this research is to understand how political, institutional and social actors, especially the government, the courts, the human rights and transitional justice NGOs, and victims associations, frame the mechanisms of transitional justice and use legal instruments to transform the conflict and reach what they consider “justice.” It also attempts to understand the relations between politics and law in the context of a hegemonic discourse of security and give an account of the expressions of resistance of human rights networks.
