On Thursday, September 19, the Brazilian Supreme Court (STF) unanimously decided to annul a municipal law from Santa Cruz de Monte Castelo in Paraná that intended to implement the 'School Without Party' program. Proponents of this law argued that it aimed to combat what they considered political and ideological indoctrination in schools, ensuring that mandatory curriculum content would not conflict with the religious or moral beliefs of students or their families.

However, the court ruled that the legislation was incompatible with constitutional principles, particularly the freedom of teaching, expression, and thought. This decision highlights the tension between educational content regulation and the constitutional rights of individuals in Brazil. The opinion was delivered by Minister Luiz Fux, supported by other notable justices including Flávio Dino, Cristiano Zanin, and Dias Toffoli, among others.

This ruling is significant within the ongoing debate regarding educational policy in Brazil, particularly in how educational ideologies are framed and taught in schools. By nullifying the 'School Without Party' program, the STF has reaffirmed the importance of academic freedom and the need to protect diverse viewpoints within the educational system, potentially influencing future policies and legislation.
