Key Points
—Brazil’s Congress overrode President Lula’s veto on the Dosimetria Law by 318 to 144 in the Chamber and 49 to 24 in the Senate, the second major government defeat in 24 hours.
—Bolsonaro’s 27-year, three-month coup sentence is projected to fall to between 22 years one month and 24 years 10 months under the new sentencing rules.
—At least 190 January 8, 2023 coup defendants qualify for sentence recalculation, per Justice Alexandre de Moraes’ April count.
The Brazil Dosimetria law tests whether Congress can dismantle the legal architecture that produced Bolsonaro’s 27-year coup conviction, less than 24 hours after the Senate rejected Lula’s Supreme Court nominee for the first time in 132 years.
The new Brazil Dosimetria law could cut former president Jair Bolsonaro’s 27-year, three-month coup conviction by as much as five years. Brazil’s Congress overrode President Luiz Inácio Lula da Silva’s veto on Thursday evening, with 318 deputies and 49 senators voting to reduce penalties for those convicted in the January 8, 2023 coup attempt.
The Chamber of Deputies vote was 318 against the veto and 144 in favor, with five abstentions. The Senate followed with 49 to 24, sending the bill to promulgation. The Rio Times, the Latin American financial news outlet, reports that the override marks Lula’s second devastating Congressional defeat in 24 hours.
How the Brazil Dosimetria Law Changes Sentencing
The legislation rewrites how courts add penalties when a defendant is convicted of multiple crimes from one event. Under previous rules, judges stacked sentences for related offenses such as attempted coup and the violent abolition of the democratic order, producing the long terms imposed on Bolsonaro and his co-defendants.
The new rule applies only the harshest single sentence, increased by between one-sixth and one-half. The bill also reduces penalties by one-third to two-thirds for crimes committed in the context of a crowd, provided the defendant did not finance or lead the action. The benefits apply retroactively, including to those already definitively convicted.
Professor Gustavo Badaró of the University of São Paulo told Brazilian outlets that, in Bolsonaro’s case, the absorption rule means the conviction for attempted abolition of the democratic order should be folded into the more serious coup charge. With the minimum increase of one-sixth, his sentence drops to roughly 22 years and one month, while the maximum increase of one-half lands it at 24 years and 10 months. Time-off mechanisms such as remission for reading or work could further accelerate his progression.
The Alcolumbre Maneuver
Senate President Davi Alcolumbre executed an unusual procedural move before the vote. He stripped from the override the provisions that would have eased regime progression for convicts of heinous crimes such as femicide. Those clauses conflicted with the Anti-Faction Law, which Lula sanctioned in March of this year.
By severing those parts, Alcolumbre allowed Congress to focus the vote narrowly on January 8 convicts. The opposition leader in Congress, Deputy Bia Kicis (PL-DF), called the maneuver “wise both technically and politically.” The text now heads to promulgation, with President Lula given 48 hours to sign — and if he declines, the Senate president takes over the duty.
A Government in Free Fall
The override followed by less than a day the Senate’s rejection of Lula‘s nominee Jorge Messias for the Supreme Federal Tribunal, the first such rejection in 132 years. Government leader Senator Jaques Wagner reacted that “the constitutional pact lost” and that political disputes have “other territories” than Supreme Court picks.
Bolsonaro is currently under house arrest for health reasons but technically remains in closed regime. His son, Senator Flávio Bolsonaro, told allies the former president was “very happy” upon learning of the vote. Senate rapporteur Esperidião Amin (PP-SC) called the bill “the first step” and said the next goals are full amnesty and a review of the January 8 inquiry.
Lula made a national television address the same Thursday evening, just hours after the override, but did not mention either defeat. He focused instead on a debt renegotiation program and a push to end Brazil’s six-day work week. The silence was notable: as the Messias rejection and the dosimetria override unfolded, Lula’s third-term project lost its grip on Congress in 24 hours.
What Comes Next for Bolsonaro
The recalculation of Bolsonaro’s sentence will be handled by Justice Alexandre de Moraes, who oversees the criminal execution of the coup case. The new law will apply automatically to Bolsonaro and 190-plus other defendants identified by the Supreme Court. Constitutional challenges to the law are widely expected, and the court has not signaled how aggressively it will read the absorption rule.
The political pressure on the court has shifted dramatically. The Brazilian Supreme Court now operates with one of its 11 seats vacant and a Congress willing to defy it. For Lula, the calendar is brutal — October’s general election is six months away, and his party’s narrative that the January 8 plotters faced full justice has been hollowed out by his own Congress.
