Abstract This paper aims to demonstrate how the constitutional guarantees of the right to vote and the constitutional design of the Electoral Judiciary have protected electoral integrity in Brazil during the Bolsonaro administration. The 1988 Constitution entrenched voting rights, expanded suffrage, and adopted compulsory voting, creating inclusive voting practices that facilitate voter turnout. The constitutional system also provided for an independent Electoral Judiciary that operates on all levels of electoral governance, including rulemaking. As the sole electoral management body in the country, the Electoral Judiciary generated a process of positive feedback that reinforced its authority. This process has also been guaranteed by the institutional linkage of the Superior Electoral Court with the Federal Supreme Court, where the latter acts as a self-referencing veto point, upholding the decisions of the Electoral Judiciary. Keywords: voting rights, electoral management, electoral justice, Brazilian election law.
