PGR Says Rio Grande do Sul Betting Advertising Law Is Unconstitutional
Brazil.- 19 August 2026 | www.zonadeazar.com Brazil’s Office of the Prosecutor General (PGR) has urged the Federal Supreme Court (STF) to declare unconstitutional a Rio Grande do Sul law imposing specific restrictions on online betting advertising.
The position was submitted in proceedings brought by the National Association of Games and Lotteries (ANJL), which argues that the state exceeded its authority by legislating on an area that should be governed at federal level.
PGR Supports Exclusive Federal Authority
The opinion was signed by Prosecutor General Paulo Gonet.
The PGR argues that fixed-odds betting advertising requires a clear and uniform federal framework because of the potential risks to consumers, minors, vulnerable individuals, the national economy and public security.
According to the Prosecutor General’s Office, allowing different rules in individual states could create:
- Legal uncertainty.
- Regulatory asymmetries.
- Enforcement difficulties.
- Uneven levels of consumer protection.
ANJL Challenge
The PGR’s opinion forms part of a lawsuit filed by the National Association of Games and Lotteries (ANJL).
The association argues that Rio Grande do Sul intruded on federal legislative powers by creating its own betting-advertising rules.
The case is being overseen at the Supreme Court by Justice Cármen Lúcia.
PGR Seeks Final Invalidation
The Prosecutor General is not simply supporting a temporary injunction against the legislation.
Paulo Gonet has asked the Supreme Court to uphold the ANJL challenge on a definitive basis and invalidate the state law as unconstitutional.
The final decision will rest with the STF.
What the Rio Grande do Sul Law Requires
The law was sanctioned in April by Governor Eduardo Leite.
Its main provisions include a prohibition on betting-platform advertising in:
- Stadiums.
- Gymnasiums.
- Sports venues.
- Public entertainment venues.
Exceptions apply when a betting company is an official sponsor of the event, holds naming rights for the venue or is an official sponsor of one of the participating teams.
Mandatory Warnings
The legislation also requires all betting advertisements to contain clear warnings about gambling-related risks.
Messages must address issues including:
- Addiction risk.
- Potential financial losses.
- The prohibition on gambling by people under 18.
Warnings must occupy at least 15% of the advertising area and be given prominence equivalent to the main promotional message.
The requirement also applies to audio advertising.
Advertising Time Restrictions
The law additionally limits when betting advertisements may be broadcast.
On television, radio, streaming platforms and video-on-demand services, gambling advertising would only be permitted between 9pm and 6am.
Entry into Force
The legislation was sanctioned on 24 April 2026 and introduced a 120-day implementation period.
The restrictions are therefore scheduled to take effect towards the end of August.
The timing makes the Supreme Court’s review particularly significant for operators and advertisers.
Regulatory Context
The dispute raises a central question for Brazil’s regulated betting industry: how far individual states can go in imposing additional requirements on an activity already governed by federal rules.
The PGR believes state-by-state advertising regulation would undermine the development of a consistent national framework.
Next Steps or Impact
The Federal Supreme Court must now decide whether to uphold the Rio Grande do Sul legislation or accept the argument that the state exceeded its constitutional authority.
A ruling that the law is unconstitutional could restrict other states’ ability to introduce their own betting-advertising requirements.
Conversely, a decision in favour of Rio Grande do Sul could create greater room for additional state-level regulation within Brazil’s betting market.
