Brazil's Supreme Court, court-curbing, reform, attacks, impeachmentAbstract
This article examines court-curbing initiatives and delegitimizing pressures directed against Brazil’s Supreme Court between 2019 and 2022, a period of intense political polarization and expanding autocratic legalism. It distinguishes reforms and criticisms compatible with democratic accountability from attacks aimed at weakening the Court’s legitimacy and constraining its authority. Based on documentary research, the study maps and classifies impeachment petitions, constitutional amendment proposals, and media texts containing criticisms of or attacks on the Court. The findings show that, while some initiatives remained within legitimate institutional dissent, others operated as instruments of institutional pressure or symbolic delegitimation, combining low-feasibility legislative offensives with highly visible public attacks. In this context, Brazil’s Supreme Court became a central target of sustained delegitimization efforts aimed at undermining both its diffuse and specific legitimacy. The case illustrates a broader paradox of courts under stress: visibility may strengthen judicial authority while increasing vulnerability to political and symbolic attacks.
