Brazil promulgated the Estatuto da Criança e do Adolescente (ECA). The law established comprehensive legal protections for children and adolescents nationwide. It recognized minors as full subjects of rights under Brazilian law. The statute defined responsibilities for families, society, and the state. It introduced safeguards in education, health care, and social assistance. The ECA also reformed how juvenile justice cases are handled. The law remains a foundation of Brazil’s child-rights policy.
