Brazil’s Supreme Federal Court resumes and will rule on whether the 1941 gambling ban still fits the Constitution

The Supreme Federal Court (STF) is set to hear whether Article 50 of the 1941 Lei das Contravenções Penais, which criminalizes the operation of games of chance, conflicts with Brazil’s 1988 Constitution and the principle of free enterprise. For high-risk operators, the point is simple: this is not about policy commentary, it is about whether a decades-old criminal ban keeps standing as a live enforcement tool.

1. The STF resumes in-person hearings on Monday (3) after the judiciary recess, with the first session of the second half of the year scheduled for 2 p.m. That day’s first agenda item is unrelated: tax exemptions for vehicle purchases by people with disabilities.
2. On Wednesday (5), the Plenary will discuss RE 966177, under general repercussion (Theme 924), which asks whether Article 50 of the Lei das Contravenções Penais (Decree-Law 3.688/1941) violates the constitutional principle of free enterprise by banning the exploitation of gambling.
3. Under the current law, anyone who organizes or maintains this type of game can be punished by the courts with a fine and other penalties provided by law. The court is now examining whether a rule written in 1941 still matches the Federal Constitution or has become obsolete in constitutional terms.
4. The concrete case comes from the Public Prosecutor’s Office of Rio Grande do Sul, which challenged a ruling by a Criminal Special Court panel that treated gambling operations as atypical conduct, effectively saying they no longer fit the old misdemeanor framework because the constitutional basis for the ban does not hold up under the current Constitution.
5. Reporting on the case, Justice Luiz Fux said the issue is constitutionally significant from an economic, political, social, and legal standpoint. He also noted that all Criminal Special Court panels of the Rio Grande do Sul Court of Justice have taken the same view, meaning gambling is no longer being treated there as a penal contravention.

Article 50 says that establishing or operating games of chance in a public place, or a place accessible to the public, with or without an entry fee, is a criminal misdemeanor. The STF’s answer will matter well beyond Brazil’s courtroom jargon, because it determines whether the legal risk around gambling remains anchored in criminal law or starts to fall away.
