Brazil Prosecutor General Backs Challenge To State Betting Advertising Law

Brazil’s Prosecutor General’s Office (PGR) has issued an opinion supporting a constitutional challenge against legislation imposing state-level restrictions on sports betting advertising in Rio Grande do Sul.

The Direct Action of Unconstitutionality (ADI) challenges Law No. 16,508/2026, which introduced specific advertising requirements for fixed-odds betting within the state.

In its assessment, the PGR argued that Rio Grande do Sul had legislated on an issue that falls within the exclusive jurisdiction of the federal government.

The National Association of Games and Lotteries (ANJL) has welcomed the opinion, arguing that maintaining betting regulation at federal level provides greater legal certainty for licensed operators.

PGR Calls For Suspension Of State Law

The PGR argued that creating an individual set of state restrictions governing betting advertising is incompatible with Brazil’s Constitution because the subject requires a unified federal framework.

Its opinion calls for the immediate suspension of the Rio Grande do Sul legislation and supports making the injunction permanent.

Such an outcome could have wider implications for attempts by individual states to introduce their own restrictions in areas already covered by Brazil’s federal betting framework.

The opinion represents the PGR's position in the constitutional proceedings rather than a final ruling on the validity of the legislation.

ANJL Raises Illegal Market Concerns

ANJL said the development could help establish greater regulatory consistency across Brazil’s fixed-odds betting sector.

The association also linked the issue to the continuing challenge posed by unlicensed gambling platforms, arguing that consistent federal requirements are important when attempting to channel consumers towards regulated operators.

According to ANJL, allowing different states to impose separate requirements could create additional complexity for licensed businesses while illegal operators continue to operate outside the country's regulatory framework.

ANJL president Plínio Lemos Jorge welcomed the PGR's position.

“The ANJL commends the Prosecutor General’s Office for the decision and for the commitment shown to legality, legal certainty, and the responsible development of the gaming and lottery sector in Brazil,” Jorge said.

The constitutional challenge will ultimately determine whether Rio Grande do Sul can maintain its own betting advertising requirements alongside the rules established at federal level.
