Kassio Nunes Marques was sworn in as president of the Tribunal Superior Eleitoral (TSE) on Tuesday, May 12, 2026 [1].
The appointment places Nunes Marques at the helm of Brazil's electoral authority during a critical window before the general elections in October 2026 [3]. As the lead official, he is responsible for the administration and legal integrity of the voting process in a highly polarized political environment.
The ceremony took place in Brasília, Distrito Federal [2]. The event was attended by high-profile political figures, including President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro [2]. Alongside Nunes Marques, André Mendonça assumed the role of vice-president of the court [1].
During the proceedings, Nunes Marques addressed the stability of the voting system. "As urnas eletrônicas são patrimônio institucional da democracia," he said [3]. The statement translates to the electronic voting machines being an institutional heritage of democracy.
The transition of leadership comes as various political factions express their expectations for the judiciary's role in the upcoming cycle. Flávio Bolsonaro said via Metrópoles, "Espero um TSE imparcial" [4]. This translates to an expectation for an impartial Electoral Court.
The TSE is tasked with ensuring that the upcoming October elections are conducted according to law, managing everything from candidate registration, to the final tally of votes [3]. The court's leadership is central to maintaining public trust in the electronic ballot system, which has been a point of contention in previous cycles [3].
“"As urnas eletrônicas são patrimônio institucional da democracia."”
The installation of Kassio Nunes Marques as TSE president occurs just months before a general election. By affirming the legitimacy of electronic voting machines and facing calls for impartiality from opposition figures, the court's leadership must now balance the technical administration of the vote with the political necessity of maintaining institutional neutrality to prevent post-election unrest.
