Leading up to the second round of the 2026 presidential election, Supreme Federal Court (STF) Justice Edson Fachin emphasized the importance of institutional rules and judicial decisions. He warned that democracy can erode progressively through the gradual capture of institutions and the weakening of oversight mechanisms.

Following the election, which involved a contentious period between Luiz Inácio Lula da Silva and Flávio Bolsonaro, STF Justice Gilmar Mendes criticized the leadership of the Superior Electoral Court (TSE). While Mendes credited the TSE collective body for maintaining democratic integrity, he argued that the head of the electoral body should act as an “equidistant referee” and cautioned that a lack of decisive leadership can lead to contradictory decisions.
