The Brazilian Public Prosecutor’s Office is an institution endowed with broad autonomy and significant discretionary power, particularly in its electoral function, where prosecutors are responsible for overseeing the legality and integrity of the democratic process. Based on national survey data collected from members of the Public Prosecutor’s Office who work and have worked in the Electoral Justice system, this article analyzes the sociodemographic profile, professional trajectories, career motivations, and normative values of these agents. The findings show that, although the Electoral Public Prosecutor’s Office is not a distinct career track, its operation tends to be vocationally driven, with strong adherence to axiological principles. The data reveal important internal cleavages, particularly regarding political criticism and ideological diversity. These results challenge monolithic views of the institution, suggesting that its performance in the electoral arena is shaped by normative disputes, structural inequalities, and multiple rationalities. The article contributes to the scholarly debate on the role of autonomous bureaucracies in democratic governance and offers insights for improving the institutional functioning of Electoral Justice in Brazil.
