Flamengo joins Brazil’s Supreme Court challenge to the federal ban on fixed-odds betting

The thing to watch here is not just a football club filing paperwork. Flamengo has been allowed to join a Supreme Federal Court case that challenges a federal provisional measure banning fixed-odds betting in Brazil, and Palmeiras says it will join too. For PSPs, sportsbooks, and payment partners tied to the Brazilian market, this is a direct read on how far the industry is willing to push back before the law even reaches Congress.

1. On Wednesday, 30 September, Supreme Federal Court Justice Luiz Fux authorized Flamengo to join the case as an interested party. The club had filed its request the same day.
2. According to Globo Online, that move put Flamengo ahead of other Brazilian clubs that were preparing a joint filing to the STF with the same request to Fux. Palmeiras has already announced it will enter the case during the week, following Flamengo’s approach.
3. Other clubs are expected to submit individual requests. After internal discussions in the sector, the view was that multiple “friend of the court” filings would attract more visibility than one collective appearance.
4. In its statement, Flamengo said the request was not meant to defend its own interests, but to ensure that the “Supreme Court can assess, in a broad way, the concrete consequences of the legislative change for the entire sports ecosystem.” The club added that it wanted to “contribute technically to the debate, from the concrete perspective of one of the sports institutions directly affected by the measure.”
5. The original action was filed in the STF by the Associação Nacional de Jogos e Loterias (ANJL) and the Instituto Brasileiro de Jogo Responsável (IBJR), both representing betting companies. They argue that the rule could create irreversible effects before Congress has even reviewed it, and they are asking Fux to examine the issue urgently.

The provisional measure was signed by President Luiz Inácio Lula da Silva on Friday, 26 September, and took effect immediately. Since then, Flamengo president Luiz Eduardo Baptista has been speaking publicly about the federal government’s decision.
