Carmen Lúcia, a minister of Brazil's Supreme Federal Court (STF), was elected president of the Court’s First Chamber on Tuesday. She will assume the post on September 30, succeeding Justice Flávio Dino, whose one‑year term ends then.
Chamber composition and rotation
Brazil’s Supreme Federal Court is divided into two chambers, known as Turmas, each comprising five ministers. The presidency of each Turma rotates annually among its members, with no immediate reelection allowed until every justice has served as president. The First Turma currently includes Ministers Alexandre de Moraes and Cristiano Zanin, alongside Carmen Lúcia and Flávio Dino. A fifth seat remains vacant after Luiz Fux’s transfer to the Second Turma following the retirement of Luis Roberto Barroso in 2025.
The election was unanimous and symbolic, reflecting the court’s internal agreement. Carmen Lúcia’s term will run from September 30, 2026, to September 30, 2027, unless the court’s internal rules change.
Jurisdiction and recent highlights
The First Turma hears a substantial share of the STF’s docket, including cases with significant political ramifications. In recent years, the chamber has been responsible for reviewing matters linked to the January 8, 2023, riots in Brasília and the criminal proceedings that led to the conviction of former president Jair Bolsonaro. Its rulings on these topics have drawn national and international attention.
Besides the high‑profile docket, the Turma also adjudicates routine constitutional disputes, advisory opinions, and appeals from lower courts. Its workload underscores the importance of the rotating leadership model in maintaining balanced deliberations among the justices.
The chamber’s decisions often serve as bellwethers for the broader court’s direction, especially when the full plenary is deadlocked. Legal scholars note that the First Turma’s composition—featuring justices with diverse ideological leanings—tends to produce nuanced rulings that balance individual guarantees against state interests. This dynamic has been evident in recent rulings on campaign finance, environmental regulation, and indigenous land rights.
Background on the incoming president
Carmen Lúcia entered the STF in 2006 after a distinguished career as a federal prosecutor and law professor. Known for her pragmatic approach, she has previously served as president of the STF’s Second Turma and acted as interim chief justice during absences of the court’s president. Her legal philosophy emphasizes procedural rigor and respect for precedent.
Flávio Dino, who will relinquish the First Turma presidency, is a former governor of Maranhão and former minister of Justice and Public Security. He joined the STF in 2023 and has been noted for his focus on individual rights and institutional integrity. His upcoming responsibilities will include continuing his work as a regular member of the First Turma.
The leadership transition highlights the STF’s internal mechanisms for ensuring continuity and impartiality in one of Brazil’s most influential judicial bodies.
