The Advocacia‑Geral da União (AGU) asked the Supremo Tribunal Federal (STF) to declare the Dosimetria Law unconstitutional on Tuesday [1].
This legal challenge targets a law that reduces penalties and eases execution rules for individuals convicted of crimes against the Democratic State of Law. The outcome will determine whether the Brazilian state can maintain strict sentencing for those who attempt to undermine democratic institutions.
The AGU submitted the manifestation to the court in Brasília on May 19, 2026 [1]. The government body said the law is unconstitutional because it softens the consequences for crimes against the democratic order. By reducing these penalties, the AGU said the law could weaken the constitutional protections necessary to safeguard the Rule of Law [1].
The Dosimetria Law specifically targets the calculation of sentences and the flexibility of penal execution. If the STF upholds the AGU's request, the law would be voided, ensuring that those convicted of attacking democratic processes face the original, more severe penalties.
Legal experts have noted that the judicialization of this law in the STF could lead to delayed effects for those currently seeking benefits under the legislation [2]. The court must now decide if the legislative attempt to reduce sentences conflicts with the fundamental duty of the state to protect its democratic framework.
The AGU's move signals a high-level effort to ensure that legal leniency does not become a tool for those who challenge the stability of the government, a move that places the final decision in the hands of the nation's highest judicial authority.
“The AGU asked the Supremo Tribunal Federal (STF) to declare the Dosimetria Law unconstitutional.”
This legal battle represents a critical tension between legislative efforts to reform sentencing and the judicial mandate to protect democratic stability. If the STF rules the Dosimetria Law unconstitutional, it reinforces a legal precedent that crimes against the state are treated with maximum severity, potentially deterring future attempts to destabilize the democratic order through institutional attacks.
