Brazil's constitution requires party affiliation for candidates

Brazilian law prohibits running for office without party affiliation, a rule upheld by the Supreme Court. This requirement is a constitutional mandate for eligibility. The Brazilian Constitution establishes political parties as fundamental to democracy, structuring campaigns and forming political majorities. This system is designed to organize the electorate and provide predictability in elections. While independent candidacies are debated, especially during times of low public trust in parties, Brazil's legal framework prioritizes party affiliation for electoral participation.
