The Superior Electoral Court of Brazil has granted permission for federal Deputy Alessandra Haber from Pará to disaffiliate from the MDB party without the risk of losing her parliamentary seat. The decision was reached with a vote of 6 to 1, highlighting allegations of political persecution that Deputy Haber faced within her party. Specifically, she claimed that her political career was hindered following her husband's departure from the MDB, citing instances of isolation and restrictions on her legislative activities.

Haber, who was the most voted deputy in Pará during the 2022 elections, argued that her position within the MDB was compromised after her husband, Daniel Santos, the Mayor of Ananindeua, departed from the party in the lead-up to the 2024 municipal elections. The TSE found substantial evidence of political discrimination, allowing her to change parties without the corresponding penalty of losing her mandate. The case was overseen by Minister Estela Aranha, who noted significant concerns regarding the parliamentary representation of Haber following her husband's political shift.

This ruling has broader implications for the Brazilian political landscape, particularly concerning the rights of legislators to switch parties amidst claims of political persecution. It sets a precedent that may empower other politicians facing similar issues, signifying a judicial acknowledgment of political discrimination within party dynamics in Brazil. The result reflects ongoing tensions in Brazilian politics and the legal system’s role in mediating party relationships and individual rights in the context of political affiliation.
