Brazil’s Supreme Court sets August 8 hearing on criminalization of gambling in RE 966.177

The Brazilian Supreme Federal Court (STF) has put Extraordinary Appeal 966.177 on the calendar for August 8, ending nearly a decade of procedural drift on whether gambling remains a criminal contravention in Brazil. For PSPs, acquirers, and banks touching gaming flows, this is the kind of ruling that can change the legal backdrop for both merchants and related anti-money-laundering cases.

1. On Thursday, July 2, STF President Edson Fachin announced that the merits of the case will be heard by the Full Court on August 8. The appeal has sat for almost a decade after its general repercussion was recognized.
2. The core question is simple, at least on paper: whether the gambling ban in article 50 of Decree-Law 3,688/1941, the Penal Contraventions Law, was carried over by the 1988 Federal Constitution. Until the STF answers that, criminal contravention and money-laundering proceedings tied to gambling have been held up across the country.
3. The case reached the Court in April 2016, when the Public Prosecutor’s Office of Rio Grande do Sul appealed a decision from the state’s Special Criminal Court panel. The defendant, Guilherme Tarigo Heinz, had been accused of operating gambling, but the panel treated the conduct as non-criminal, citing constitutional principles including free enterprise and fundamental freedoms in articles 1, IV, 5, XLI, and 170 of the Constitution.
4. In November 2016, the STF’s Virtual Plenary recognized general repercussion by majority. Ministers Edson Fachin and Dias Toffoli dissented. Reporting at the time, rapporteur Minister Luiz Fux noted that all criminal appeal panels of the Rio Grande do Sul Court of Justice had found the conduct in article 50 to be non-criminal on constitutional grounds, and said that in that state “the practice of gambling is no longer considered a criminal contravention.”
5. The case has been scheduled before and then slipped off the agenda. On September 9, 2020, on the eve of taking over as STF president, Fux asked for RE 966.177 to be placed on the docket. On December 17, he included it for a hearing on April 7, 2021, alongside five other cases, but an eleventh-hour addition — ADPF 811, on in-person religious services during the pandemic — crowded the session. As the sixth item on the list, with two priority cases already consuming the available time, RE 966.177 was not reached.

For high-risk operators, the practical point is not just whether gambling is legal or illegal in Brazil in the abstract. It is that the STF’s answer can alter how courts treat related criminal and AML proceedings, which in turn affects the risk profile for payment processing, acquiring, and banking relationships tied to gaming merchants in the country.
