What Ministério Público do Rio de Janeiro does

The Ministério Público do Estado do Rio de Janeiro (MPRJ) is the constitutional public prosecution institution of the State of Rio de Janeiro, Brazil, established under the 1988 Federal Constitution as an independent branch of government. It exercises exclusive legal authority over criminal prosecution, civil actions on public interests, anti-corruption enforcement (via the specialized GAECO unit), environmental protection, consumer rights, and oversight of public administration. MPRJ employs approximately 281 staff and operates from a central headquarters in Rio de Janeiro plus regional support centers (CRAAIs) in Campos dos Goytacazes and Itaperuna, serving 92+ municipalities across the state.

Its core technology asset is the Módulo Criança e Adolescente (MCA), an in-house online database launched in 2007 that tracks the socio-familial and legal status of children and adolescents in institutional or foster care. The MCA has produced 30+ census editions and is integrated with the national Sistema Nacional de Adoção (SNA) and Cadastro Nacional de Adoção (CNA) under cooperation agreements with the CNJ and CNMP signed in 2009. Supporting platforms include Radar MPRJ (investigative analytics), the PLID missing-persons program, Portal SEI (administrative processes), the Maria da Penha Virtual service for domestic violence protection orders, and the 2024-launched AI platform and digital work environment supported by the Núcleo de Ciência de Dados (NCD).

MPRJ does not operate a commercial revenue model. As a state autarchy, it is funded entirely through the Rio de Janeiro state treasury and public budget allocations. Services are delivered directly to citizens and institutional partners free of charge, with no pricing structure, subscription fees, or commercial customers. Its 'customers' in functional terms are the state population, the protection network (prosecutors, judges, social workers, Child Welfare Councils, shelter institutions), and partner entities such as the TJ/RJ, municipalities, universities, and civil society organizations.

• Ministério Público do Estado de Minas Gerais (MPMG): State-level public prosecutor in Minas Gerais with the same constitutional mandate as MPRJ — prosecution, child protection, consumer, environmental, anti-corruption — making it a direct operational peer.
• Ministério Público do Estado de São Paulo (MPSP): State-level public prosecutor's office for São Paulo under Brazil's 1988 Constitution, performing the same criminal prosecution, civil action, and child protection functions as MPRJ but serving a larger jurisdiction.

Regional players

• Ministério Público de Portugal: Portuguese public prosecution service performing the same criminal prosecution and public-interest litigation role as MPRJ, but operating under Portuguese (rather than Brazilian) constitutional and statutory framework.
