Special Committee Formed on Proposal to Lower Criminal Majority Age

Brazil’s lower house, the Chamber of Deputies, is set to install a special committee this Wednesday to examine a proposed constitutional amendment (PEC) that would reduce the age of criminal majority from 18 to 16 years. The move was formalized by Chamber president Hugo Motta (Republicanos-PB), who named deputy Aluísio Mendes (Republicanos-MA) as the committee’s chair and deputy Mendonça Filho (PL-PE) as rapporteur. The amendment had already cleared the Constitution and Justice Committee (CCJ) earlier, clearing the way for this deeper analysis.

The proposal is a long-standing demand of right-wing parties and has gained traction in an election year where public security ranks among voters’ top concerns. If approved, the text would alter the Constitution to define that criminal liability fully attaches at 16, allowing teenagers of that age to be tried and incarcerated as adults. Despite the committee’s installation, Motta’s allies signal that a floor vote is unlikely before the October elections, partially because the Chamber leader views the issue as sensitive and believes it should be accompanied by a broader review of the prison system.

Why Hugo Motta Moved the Majority Age Debate to a Separate Track

Motta’s Political Calculus

By installing the committee now, Hugo Motta satisfies a vocal faction of his base while simultaneously managing expectations. Shortly after the topic was initially included in a broader Public Security PEC—also reported by Mendonça Filho—Motta intervened to remove the age reduction chapter from that omnibus reform and promised a separate debate. This keeps a campaign-friendly issue alive without allowing the complex prison system discussions to delay the rest of the security package. Motta’s stance, as relayed by aides, is that any lowering of criminal majority must be paired with realistic plans to handle an influx of younger inmates into an already strained penitentiary system.

Election-Year Dynamics

With public security dominating voter surveys, the special committee’s work will serve as a platform for both advocates and critics to shape their electoral messaging. Right-wing parties can claim momentum, while opponents—including many in the legal and human rights communities—will use hearings to highlight overcrowding and the controversial track record of the juvenile detention system. The practical timeline, however, suggests that even a committee report would emerge too late for a lower house vote in 2026. The Senate’s eventual review and a potential push to 2027 make the amendment a issue for the next government rather than a pre-election deliverable.

Mendonça Filho’s Role

As rapporteur, Mendonça Filho holds significant sway over the final text. His earlier work on the public security PEC and his party affiliation (PL) indicate a favorable disposition toward lowering the age, but he will also need to navigate Motta’s insistence on addressing prison infrastructure. The rapporteur may introduce amendments that tie the constitutional change to concrete investments in the penitentiary system or to alternative sentencing models for 16- and 17-year-olds, balancing hardline rhetoric with administrative realism.

What to Expect from the Lower House Special Committee on Criminal Majority

  • For political parties: The committee’s composition and early hearings will signal how hardline or reform-oriented the final report will be. Right-wing benches will press for a clean cut to 16, while centrist allies of Motta may push for language linking the reduction to prison system capacity requirements. Engaging with the rapporteur at the drafting stage could prove more effective than floor fights later.
  • For public security advocates: This committee is the best chance to insert safeguards—such as differentiated treatment for adolescents, mandatory psychosocial evaluations, or the gradual phase-in of any new rule—before the proposal reaches the plenary. Motta’s stated desire for a broader prison review provides an opening to argue that the current infrastructure cannot safely absorb 16-year-olds.
  • For the electorate: Voters should expect the topic to be heavily used in campaign rhetoric, but the constitutional change will not be decided before elections. The outcome will depend on the next Congress and the new government’s priorities, making the committee’s work a starting point for a debate that will stretch into 2027.
