CELS is an organisation working to protect and promote human rights. It was created in 1979 by a group of families of victims from the military dictatorship. Since then, CELS has fought against impunity in cases of serious human rights violations committed during the dictatorship, as well as cases of structural human rights violations committed during the current democratic system. The work plan of CELS includes critical themes such as citizen security, police brutality, prison conditions, economic, social and cultural rights, judicial institutions strengthening, access to justice for vulnerable populations, and the democratisation of armed forces. The intervention strategies of CELS are varied and include investigation, advocacy and litigation in cases of human rights violations, etc.
