Brazil’s Chamber of Deputies is moving toward a narrowly tailored proposal that would allow criminal liability from age 16 for heinous crimes, intentional homicide and bodily injury resulting in death. The general age of criminal responsibility would remain 18, distinguishing the current debate from earlier, far broader drafts that also contemplated full civil adulthood at 16.¹

The Chamber proposal also centres on separate detention. Teenagers aged 16 and 17 convicted under the exception would not serve sentences alongside adult prisoners or with young people in the standard socio-educational system. Supporters present that separation as a way to impose stronger penalties for serious violence without exposing adolescents to older offenders.²

Yet the limited scope does not settle the political argument. Rapporteur Mendonça Filho has said his personal view is that the threshold should be reduced to 16 for every offence, but he signalled that his report may be narrower in pursuit of enough votes. “When you want to approve something, you have to have the capacity to listen, you have to have the capacity to dialogue,” he said.¹

The Senate debate offers competing models. One proposal would retain the age-18 rule except for formally designated heinous crimes; another would make 16 the general threshold and set 14 for offences including torture, drug trafficking, terrorism and participation in criminal organizations. Other senators argue that changing the constitutional age could face legal challenges and instead back legislation doubling the maximum period of socio-educational detention for extremely serious offences.¹

Timing has become part of the dispute. The Chamber’s special committee is holding hearings ahead of a planned report by November 30, while Senate leaders have organized a route to bring their own proposals directly to the floor if deputies have not completed their work by December 1.²
