The Brazilian Supreme Court (STF) issued a ruling on Friday (13) declaring that the legal flexibility allowing events in São Paulo to operate without noise limits is unconstitutional. This decision, made by Minister Cármen Lúcia, effectively nullifies any future special noise permits for religious festivities, concerts, sports events, Carnival rehearsals, June festivals, and activities in educational institutions that were previously included through a parliamentary amendment.

The ruling was a response to appeals from both the São Paulo City Council and the administration of Mayor Ricardo Nunes (MDB), who had previously approved specific noise allowances as part of a broader legislative initiative aimed at modifying aspects of the city's Master Plan and Zoning Law for 2024. The court's decision upholds stricter regulations on noise control in the city, reflecting ongoing concerns over public disturbance and the quality of urban life.

As of the ruling's announcement, the City Council stated that it had not yet been formally notified and that its legal department would review the decision's implications. The city administration has yet to comment on the ruling. This legal development is significant for São Paulo residents who have long grappled with noise pollution issues, balancing cultural events with the need for community peace and quiet.
