The Public Ministry of São Paulo (MP-SP) has requested the immediate suspension of Piracicaba's new Tax Code, which was approved with only a month of discussion in the City Council, describing the process as disproportionate and abusive. The new code, comprising 588 pages, revokes 27 existing laws and revises various municipal tax regulations, including those for the Urban Property and Land Tax (IPTU), the Transfer Tax for Real Estate (ITBI), and the Tax on Services of Any Nature (ISSQN).

If the court accepts the injunction, previous rules and tax amounts will be reinstated while the MP-SP insists that the municipal government must reintroduce tax changes through a thorough legislative process. This highlights the legal scrutiny regarding local government actions concerning taxation and public policy, ensuring adherence to established legislative practices.

The controversy raises questions about the procedural integrity of the council's decision-making and the implications for local governance, as municipal tax adjustments can significantly impact residents and businesses. The MP-SP's actions indicate a vigilant approach to accountability in governmental processes, aiming to ensure that significant legislative changes undergo rigorous discussion and study before implementation.
