The purpose of this study is to analyse the manner the Brazilian Supreme Court's (Supremo Tribunal Federal - STF) decisions have influenced the institutional design of the national monetary council and the Brazilian Central Bank. During the last 20 years, STF provided limits to the power of these public authorities, by judging Direct Actions of Unconstitutionality (ADIns). This research is based on empirical study that intends to identify the actors and the issues submitted to the court and how its decision enforced their power of regulating the financial system. As a result, it is possible to perceive directions to enact the law that intends to regulate the financial system and eventually to attribute the independence to the Brazilian Central Bank.
