The Supreme Federal Court (STF) of Brazil held a public hearing on June 27, 2025, to discuss parliamentary amendments, convened at the request of Flávio Dino, the rapporteur of the related cases. Initially, Hugo Motta, President of the Chamber of Deputies, and Davi Alcolumbre, President of the Senate, were expected to attend and defend the power of Congress over these amendments. However, both Motta and Alcolumbre ultimately decided not to participate, sending representatives instead. Following this event, amid an ongoing tax on financial transactions (IOF) crisis, Alcolumbre announced plans to propose legislation to limit which political parties can appeal to the STF against decisions made by Congress. His proposal aims to restrict access to the Supreme Court by requiring parties to hold a minimum number of seats in Congress to file such challenges. This initiative is seen as a response to judicial interventions by parties like PSOL and Novo, which have contested congressional legislation in the STF. Alcolumbre's move has sparked debate about the balance of power between the legislative and judicial branches in Brazil.
