The Brazilian Federal Supreme Court (STF) presents a complex and often intriguing contrast to other global judicial bodies, such as the Supreme Court of the United States (SCOTUS). Brazilian constitutionalism is characterized by multiple high courts, each endowed with specific domains of authority. Among them, the STF exercises ultimate jurisdiction over constitutional interpretation. Unlike SCOTUS, all Brazilian judges can disregard statutes they deem unconstitutional, but constitutional review primarily falls under the STF’s purview, with significant discretion in determining its jurisdiction. Detailed information can be accessed via the Brazilian Federal Constitution.
The STF, composed of eleven justices between the ages of 35 and 75, requires presidential appointment and Senate approval for its justices. While originally set to mandate retirement at age 70, a constitutional amendment extended this to 75 in 2015. There are no specific terms, allowing some justices to serve for decades.
The STF’s jurisdiction includes both appellate and original matters. It handles thousands of cases annually, driven mainly by a vast appeals docket. Between 2000 and 2025, the court delivered over 2.9 million decisions. This number is partly attributed to the rejection of vertical stare decisis, leading to repetitive appeals. The court utilizes mechanisms like Sumula Vinculante and Repercussão Geral to manage workloads, resulting in a more stable number of appeals in recent years.
One of the court’s distinctive competencies is its abstract review procedures, allowing constitutional review without specific case context. This expansive scope can include immediate challenges to legislation and omissions and can be initiated by political parties and civil society organizations. As a further competence, the STF holds sole and final jurisdiction over criminal investigations involving federal authorities, such as governmental members and the president, as seen with former President Bolsonaro’s conviction following the January 8, 2023, governmental building invasions.
Decisions in the STF are generally by majority vote among the eleven justices or within chambers of five, although individual justices often deliver decisions due to workload delegation. Unlike SCOTUS, which typically produces majority opinions, the STF operates as a seriatim court, where each justice provides individual opinions, contributing collectively to the decision. Public deliberations enhance transparency, with sessions broadcasted live.
The STF addresses a wide range of social and political issues. Recent decisions include expanding racist crime definitions to encompass homophobia and transphobia, defending against restrictions on state and municipal public health measures during the COVID-19 pandemic, and establishing governance rules pertaining to digital platform liability for disinformation.
Though the Brazilian judiciary is perceived as highly political, it is not necessarily partisan. Decisions often reflect political climates and public opinion. The STF’s expansive jurisdiction and modus operandi make it a powerful entity, comparable to the legislative and executive branches. Its ability to engage directly with political processes and judicial proceedings underscores its significant influence within Brazilian governance.
