Zambelli Resigns After Court Overrules Congress, as Italy Weighs Extradition

Key Points

1. Carla Zambelli resigned on December 14 after a Supreme Court order enforced her immediate removal; her substitute is expected to take the seat on December 15.
2. The dispute tested whether Congress can block the loss of office after a final criminal conviction that includes prison time.
3. Detained in Rome since July, Zambelli faces a December 18 Italian hearing on Brazil’s extradition request.

Carla Zambelli’s resignation landed late Sunday and, from abroad, could look like routine turnover. It is a snapshot of Brazil’s post-Bolsonaro fight over the judiciary’s expanding role in political life.

On December 10, the Chamber of Deputies voted on whether to remove Zambelli. The effort failed to reach the absolute majority required: 227 voted for removal, 110 against, and 10 abstained—below the 257 votes needed.

Justice Alexandre de Moraes annulled the Chamber act that formalized the outcome, calling it unconstitutional, and ordered her seat vacated. On December 12, the Supreme Federal Court’s First Panel unanimously upheld Moraes.

His view is that, after a final criminal conviction with a prison sentence, the Judiciary determines the loss of mandate and Congress is limited to declaring it.

Zambelli replied in political terms. In her resignation letter, she said she was leaving to create a “historical record,” cited 946,244 voters, and cast the episode as an unelected override of representation.

Supporters echoed that warning online, arguing that judicial power is being stretched. Critics countered that final convictions must have immediate consequences, including for elected officials.

The criminal case is the core. Zambelli’s conviction became final on June 7, 2025. She was sentenced to 10 years in prison and a fine for crimes tied to a 2023 intrusion into systems associated with Brazil’s National Justice Council, plus falsification allegations.

She left Brazil seeking asylum, citing political persecution and her dual Italian citizenship, but was arrested in Rome in July. Now the story shifts to Italy.

Judges have demanded information about Brazilian prison conditions and where she would be held if extradited. The December 18 hearing will decide whether she returns—and how a foreign court weighs Brazil’s assurances. Nothing in this account was invented.
