This study, entitled Invisible (In)Racism in Juvenile Justice: Zone of Non-Being and Resistance in Incarceration, investigates the manifestations of structural racism in the Brazilian juvenile justice system, with an emphasis on the application of the socio-educational measure of incarceration to Black adolescents. Based on a qualitative and critical approach, combined with the author s professional experience as a public defender in the state of Rio de Janeiro, the study analyzes how the racialization of these adolescents is systematically rendered invisible under the discourse of legal neutrality. Drawing on the theoretical contributions of Frantz Fanon — particularly the concept of the zone of non-being — the research highlights the persistence of punitive and selective practices based on menorismo, even after the normative advances brought by the 1988 Federal Constitution and the Statute of the Child and Adolescent. The dissertation is structured around three main axes: first, a historical-critical analysis of juvenile justice and the production of violence against Black bodies; second, a reflection on the socio-educational system as a space of dehumanization and the maintenance of the coloniality of power, knowledge, and being; and third, the identification of pathways of resistance, with an emphasis on the emancipatory role of the Public Defender s Office and the presentation of practical cases from the author s professional practice. The research thus proposes to confront the still prevailing colonial and racist logics, contributing to the development of anti-racist practices and effective access to justice for adolescents deprived of liberty.
