Tension between STF ministers
Minister Gilmar Mendes, dean of the Federal Supreme Court, sent a series of direct messages to Kassio Nunes Marques demanding clarifications on alleged accounts and advising him to leave the Superior Electoral Court. The tone of the communications was considered by Kassio as excessively aggressive.
Block on the app
On Tuesday, September 8, 2026, Kassio decided to block Gilmar on WhatsApp. The measure was taken after receiving several texts that, according to close sources, mixed professional recommendations with informal expressions, including the phrase "I know about crooks".
Institutional context
The divergence arises amid internal discussions about Kassio's performance at the TSE, the body responsible for organizing elections in Brazil. Gilmar, with a long trajectory in the Court, usually defends firm positions on sensitive issues of the Judiciary.
- Messages sent: demand for transparency on accounts
- Suggestion made: removal from the TSE
- Reaction: immediate block on the messenger
Repercussion in the court
The episode, although restricted to the virtual environment, reflects the climate of divergences that occasionally marks the STF plenary. None of the ministers have publicly commented on the incident so far.
