The Supreme Federal Court has opened a constitutional review that could end the criminal treatment of land-based gambling in Brazil. The case asks whether a prohibition created in 1941 can remain in force under the 1988 Constitution while licensed online betting and casino games operate nationwide.
Good to Know
- The case challenges Article 50 of the Criminal Offenses Law.
- A ruling will apply to similar gambling cases across Brazil.
- Justice Luiz Fux serves as reporting justice and will cast the first vote.
Online Regulation Reshapes an Old Legal Dispute
Brazil now authorizes private companies to offer fixed-odds sports betting and online casino games after obtaining approval from the Secretariat of Prizes and Betting.
Law No. 14.790/2023 established rules for online games, operator licensing, tax payments and federal supervision. Since January 1, 2025, only federally authorized companies can operate nationwide through domains ending in .bet.br.
However, Article 50 of Decree-Law No. 3.688/1941 still classifies the operation of games of chance in public or publicly accessible locations as a criminal offense.
Extraordinary Appeal 966177 asks the STF to decide whether that rule remains compatible with constitutional protections covering free enterprise and fundamental freedoms. The court granted the dispute general repercussion status under Theme 924, so the final interpretation will guide courts across Brazil.
The STF began hearing the case on August 5, 2026, after several earlier delays. The court heard arguments but suspended the session before any justice delivered a vote. No date for the continuation had been confirmed at the time of publication.
Defense Challenges Online and Retail Divide
The appeal grew from a Rio Grande do Sul case in which a lower court rejected the application of Article 50. State prosecutors then took the dispute to the STF.
Defense lawyers argue that Brazil applies opposing legal treatment to similar gambling products. A licensed website can offer regulated betting and online casino games, while a physical casino or bingo hall may face criminal enforcement.
According to the appeal, location alone cannot justify that difference. The defense also says Article 50 came from an earlier constitutional order shaped by public morality concepts that do not align with the 1988 Constitution.
Lawyers have asked the court to find that the current Constitution did not receive the main provision of Article 50. Such a judgment would remove the criminal classification, although it would not create a complete licensing framework for casinos and bingo halls.
Congress would still need to decide how to regulate taxation, licensing, consumer protection, anti-money laundering controls and local operating rules.
The defense also argues that prohibition has left gambling activity in an underground market rather than eliminating it. In that account, illegal operators receive the money, employees lack formal labor protection and public authorities collect no gambling taxes.
As an international comparison, the filing refers to tribal gaming under the US Indian Gaming Regulatory Act of 1988. However, official National Indian Gaming Commission data places tribal gaming revenue at $46.2 billion for the 2025 financial year, not the more than $105 billion described as annual revenue in the defense material. A higher figure may refer to wider economic output rather than direct casino gaming revenue.
A Ruling Would Not Automatically Open Casinos
A decision against Article 50 could decriminalize the operation of games of chance, but it would not immediately produce a regulated land-based casino market.
Without new legislation, Brazil could face a legal gap in which casino and bingo activity no longer carries the same criminal penalty but lacks detailed federal licensing rules.
The STF case also runs separately from proposals in Congress that would regulate casinos, bingo halls, jogo do bicho and other gambling products. The court will examine constitutional validity, while lawmakers retain authority to design a commercial regulatory system.
Justice Luiz Fux serves as reporting justice. His vote will open the judicial phase when the plenary resumes the case.
