verbatim from the press

Supreme Court Justice Alexandre de Moraes suspended on Saturday (9) the application of the Dosimetry Law — a regulation that alters penalty calculations for crimes against the Democratic Rule of Law — until the STF's full court rules on two direct constitutionality challenges questioning the law. The decision was made for "legal security," according to the magistrate, and affects requests for sentence reductions based on the new legislation.

"O ministro do Supremo Tribunal Federal (STF), Alexandre de Moraes, suspendeu neste sábado (9) a aplicação da Lei da Dosimetria"

Carta Capital

"recomendando a suspensão da aplicação da lei, por segurança jurídica, até definição da controvérsia pelo Supremo Tribunal Federal"

The suspension occurred while analyzing the case of Nara Faustino de Menezes, sentenced to 16 years and 6 months in prison for participation in the January 8, 2023 acts. The defense had requested immediate application of Law 15.402/2026, enacted on Friday (8) by Congress President Davi Alcolumbre after overturning President Lula's veto. By Saturday afternoon, Moraes had already issued at least ten similar decisions.

"o ministro já publicou dez decisões neste sentido até às 13h30 deste sábado (9)"

The constitutionality challenges were filed by the Brazilian Press Association (ABI) and the PSOL-Rede party federation, which allege the law "creates more favorable executive treatment for crimes aimed at institutional rupture," according to the STF. Among possible beneficiaries of the Dosimetry Law is former president Jair Bolsonaro, sentenced to 27 years and 3 months in prison for crimes related to the January 8 acts.

"As ações foram ajuizadas pela Associação Brasileira de Imprensa (ABI) e pela federação partidária PSOL-Rede, que avaliam a lei como instrumento para "criar tratamento executório mais favorável para crimes voltados à ruptura institucional"

A Gazeta

"Entre os principais beneficiários da nova lei está o ex-presidente Jair Bolsonaro (PL), condenado a 27 anos de prisão"

The Dosimetry Law alters Criminal Code rules to prevent, in certain situations, the sum of penalties for crimes committed "in the same context," making the most severe penalty with legally defined additions prevail. The text also provides for reductions of one-third to two-thirds for crimes practiced "in crowd context," provided the convicted party did not finance the acts or exercise leadership roles.

"Uma das mudanças impede, em determinadas situações, a soma das penas de crimes cometidos no mesmo contexto, fazendo prevalecer a pena mais grave com acréscimo definido em lei"

"O texto também prevê redução de um terço a dois terços para crimes de golpe de Estado e abolição violenta do Estado Democrático de Direito quando praticados "em contexto de multidão"
