The document discusses regulatory governance and institutions in Brazil, focusing on the Ministério Público (MP). It notes that Brazil underwent democratic and constitutional transformations in the 1980s, which strengthened the MP's independence and ability to file civil lawsuits. The Brazilian Constitution also expanded social and collective rights. However, enforcing these rights and principles through regulation poses challenges without an administrative procedure act or regulatory impact assessments. The document argues that introducing regulatory impact assessment in Brazil could help structure the proportionality principle and other standards of judicial review, improving regulatory governance.
