PSD appeals to STF to force Rio mayoral runoff after vote annulment

Brazil's PSD is challenging the annulment of Garotinho's votes in the Rio mayoral election, which pushed Douglas Ruas to 50.88% of valid votes, avoiding a second round. The appeal to the Supreme Federal Court seeks to overturn the result and force a runoff. The outcome hinges on judicial interpretation of vote validity, with implications for local political balance.
