In a move that reignites a deeply polarising debate, a key committee of Brazil's Chamber of Deputies has approved a constitutional amendment to lower the age of criminal responsibility from 18 to 16. The Commission on Constitution, Justice and Citizenship (CCJ) voted 44 to 18 in favour of the proposal, clearing the first procedural hurdle for a measure that has languished in Congress for nearly a decade. The vote, held on Wednesday, followed more than two hours of heated debate, with the rapporteur arguing that the amendment is legally sound and does not violate constitutional clauses or international treaties. The proposal now proceeds to a special committee before facing two rounds of plenary votes.

Viewed from Brasília, the approval reflects a persistent legislative push to harden the penal code amid public anxiety over youth crime. The amendment, originally introduced in 2015 by then-deputy Gonzaga Patriota, had been stalled since 2016 when former speaker Eduardo Cunha secured a prior committee vote. The current speaker, Hugo Motta, must now appoint the special committee that will scrutinise the substance of the bill. Analysts in São Paulo note that the CCJ's decision is only the beginning of a long legislative journey; the proposal must survive intense scrutiny in the special committee and then secure a three-fifths majority in two plenary rounds.

From a regional perspective, the debate echoes similar tensions across Latin America, where countries grapple with balancing punitive measures against rehabilitation for minors. In Brazil, opponents of the amendment argue that lowering the age of criminal responsibility would disproportionately affect poor and non-white adolescents, and that the prison system is ill-equipped to handle younger inmates. Human rights groups have warned that the move could violate the Statute of the Child and Adolescent and international conventions to which Brazil is a signatory. Supporters, however, contend that the current age limit shields violent young offenders from accountability and fuels impunity.

Looking ahead, the proposal's fate hinges on the composition of the special committee and the political calculus in the plenary. With a conservative majority in the Chamber, the amendment may advance, but it faces potential hurdles in the Senate, where opposition is expected to be stronger. The government of President Luiz Inácio Lula da Silva has signalled caution, preferring to focus on preventive measures rather than punitive reforms. As the legislative process unfolds, the debate will likely intensify, testing Brazil's commitment to its constitutional framework and international obligations.
