ADI 7971 RS betting-ad law: Allegations, Court Orders and Status

What this case is about

ADI 7971 (0173760-90.2026.1.00.0000) is a constitutional challenge at the Supremo Tribunal Federal (STF), Brazil's Supreme Federal Court, filed on 15 May 2026. It is one of the Advertising and Marketing Lawsuits tracked here.

The Associação Nacional de Jogos e Loterias (ANJL), an operators' association, attacks Rio Grande do Sul's state law 16.508/2026 on betting advertising. The law requires warnings, bans content that appeals to minors, and bars TV, radio and streaming betting ads between 6h and 21h. It also sets fines.

ANJL argues that the state law invades the Union's competence over lotteries and advertising. That is the association's argument, not a finding.

Who is covered

The plaintiff is ANJL. The defendants are the Governor and the Legislative Assembly of the State of Rio Grande do Sul. Minister Cármen Lúcia is the rapporteur (relatora).

If the law stands, it governs betting advertising aimed at people in Rio Grande do Sul. The case is not a class action, and players are not parties. Other Brazilian matters are collected under Gambling Lawsuits in Brazil.

Is there a payout?

No payout exists in this case. It is a challenge to a state advertising law, and the record shows no damages, fund or settlement (all money fields are BRL 0).

Players cannot file a claim, and there is no claim form or administrator.

What happens next

As of the last docket entry in the record, 25 August 2026, no injunction (liminar) has been decided. The case was filed and assigned to Cármen Lúcia on 15 May 2026, and she ordered a diligence on 25 May 2026.

The state sent its information on 1 and 2 June 2026. The Attorney General's office (AGU) gave its opinion on 9 June 2026. The Prosecutor General's office (PGR) gave its opinion on 17 August 2026. Amicus petitions followed on 23 June and 21 August 2026.

No hearing date or ruling is confirmed in the court record. The case was listed among the eight STF betting cases for the second half of 2026.

Why it matters

The case asks who may regulate betting advertising in Brazil, the Union or the states. The outcome decides whether a state can set its own warning rules and broadcast hours for bet ads.

It belongs to a set of challenges before the STF, listed below, and to the wider group of Advertising and Marketing Lawsuits Against Gambling Operators.
