São Luís mayor goes to court against a zoning law the council amended 133 times and passed over her veto

São Luís city council approved a new zoning law, Lei 8.142/2026, with 133 council amendments. On 27 October it overrode Mayor Esmênia Miranda's full veto by 17 votes to 9, and council president Paulo Victor promulgated the law on 4 November. On 5 November the city filed suit asking the court to suspend it. On 6 November Judge Douglas de Melo Martins gave the council 72 hours to produce the full legislative record of the amendments and to state its position on the suspension request, and 30 days to file its defence. The order does not suspend the law. The city government, citing a survey by its planning institute InCId, says the amendments made 283 changes to the original bill, including smaller no-build strips along river banks. Those claims have yet to be examined by the court.

The case is a clear example of a dispute between a city's executive and its legislature over upzoning, with environmental protection as the legal lever. The court has yet to rule on suspension.
