Brazil’s Attorney General’s Office (Advocacia-Geral da União – AGU) has formally petitioned the Supreme Federal Court (STF) to suspend Rio Grande do Sul’s State Law No. 16.508/2026, which enforces severe regional restrictions on fixed-odds betting advertisements.
The AGU submitted the urgent injunctive request within the scope of the Direct Action of Unconstitutionality (ADI) No. 7971, a legal challenge initially launched by the National Association of Gaming and Lotteries (ANJL). The disputed state law is currently scheduled to enter into full effect on August 25, 2026.
Conflicting Regional Frameworks and Joint Liability Parameters
The state law mandates that operators include prominent, extensive warnings detailing gambling risks across all commercial media assets, including explicit text specifying that participation by persons under 18 years of age is strictly prohibited. Furthermore, the statute restricts audiovisual sportsbook promotions to a late-night window between 9:00 p.m. and 6:00 a.m., entirely bans advertising near schools or medical centers, and grants enforcement powers to the local consumer protection agency, PROCON-RS.
Non-compliance penalties under the state act are highly punitive, including heavy corporate fines, local website blocking orders, and the potential cancellation of state operating licenses. Crucially, the law introduces a system of joint civil liability, making betting platforms, marketing agencies, media networks, and internet service providers collectively responsible for the immediate removal of any content deemed illegal by state regulators.
Exclusive Legislative Prerogative of the Federal Union
The Attorney General’s Office has outlined four core constitutional arguments in its formal filing to justify an immediate suspension of the state act. The primary argument asserts that under the Federal Constitution, the federal Union retains exclusive and absolute power to legislate on matters concerning commercial advertising.
The AGU notes that Brazil has already established a comprehensive national regulatory architecture for fixed-odds betting via Federal Law No. 14.790/2023 and sequential Ministry of Finance regulations. In the AGU’s legal estimation, the local law creates a conflicting, dual regulatory environment rather than supplementing federal guidelines:
“The maintenance of the law prior to the final decision leads to an environment of legal uncertainty that is incompatible with the need for uniform federal legislation in this matter.”
Furthermore, the AGU argues that because sports betting is classified as a lottery-related activity, it falls under the exclusive legislative domain of the federal government. The third argument objects to the state’s attempt to regulate telecommunications and broadcasting media, pointing out that dictating transmission times, forcing website blocks, and imposing removal duties on internet service providers interferes with nationally governed communication networks.
Lastly, the AGU notes that the introduction of joint liability among private business subjects violates federal civil and commercial codes.
Beyond clear constitutional violations, the federal government warns that excessive regional restrictions will impair channelisation, driving local consumers away from compliant platforms toward underground offshore networks that do not adhere to state-approved consumer protection or responsible gaming standards.
The STF will now hear formal submissions from the federal government, the ANJL, the Governor of Rio Grande do Sul, and the State Legislative Assembly. Supreme Court Justice Cármen Lúcia has officially referred the case files to the Prosecutor General’s Office (PGR) to secure a definitive institutional opinion.
