On Wednesday, Minister Luiz Fux of Brazil's Federal Supreme Court (STF) annulled two significant provisions related to indirect elections in Rio de Janeiro. Fux's ruling mandates that the six-month disconnection period required for candidates to step down from executive positions must be respected. Additionally, he ruled that voting by deputies must be conducted in secret, which are both essential elements rooted in the electoral legislation. This decision aims to ensure greater integrity and compliance within the electoral process.

The implications of Fux's ruling are particularly relevant to the pre-candidates who have been positioning themselves for the temporary mandate expected to run until the end of 2026. This situation follows the anticipated resignation of Governor Cláudio Castro, who is likely to step down in order to vie for a Senate seat. By reinforcing the legal requirements for candidacy and voting, Fux's decision disrupts the plans of several politicians who were preparing for the indirect election process, significantly altering the political landscape in Rio de Janeiro.

The ruling came in response to requests from the Social Democratic Party (PSD), which is associated with Eduardo Paes, the mayor of Rio and a pre-candidate for the direct state election in October. The case has now been forwarded to the STF plenary for further evaluation, indicating that the debate around these electoral rules will continue and could potentially reshape the upcoming elections in the region. Fux's intervention highlights the importance of adhering to electoral laws and restores a degree of formal procedure in the political atmosphere of Rio de Janeiro.
