When a ban can leave bettors less protected: the constitutional limits on ending Brazil’s bets regime

Brazil spent decades under a mostly prohibitive approach, then less than two years with a regulated betting market that introduced responsible gambling rules, age checks, self-exclusion, consumer protection, financial tracking, and sports cooperation. The government’s return to an outright ban via Medida Provisória nº 1.394, of 25 September 2026, raises a practical question for high-risk operators: can the state dismantle a protection framework without showing that the alternative offers equal or better safeguards?

1. The constitutional issue is not whether gambling can be restricted; it is whether the state can roll back a regulatory system that had already turned legal protections into operational rules. The article frames this through the principle of vedação ao retrocesso social — the prohibition on social regression — which means that once a level of statutory protection has been reached, removing it is not legally neutral and needs constitutionally adequate justification.
2. On paper, the regulated bets regime did more than authorize wagering. It embedded rules on responsible gambling, age control, self-exclusion, consumer protection, financial monitoring, and cooperation with sports authorities. The point matters for PSPs and acquirers because the compliance stack is not decorative: it is the mechanism that separates a monitored market from a purely offshore or clandestine one.
3. The article argues that the regime protects several constitutionally recognized interests, not only the bettor’s ability to place a wager. First comes leisure: betting remains a recreational activity, even if it carries risk. Second comes health: regulated operators can identify problematic or compulsive behavior, restrict platform access, implement self-exclusion, and impose responsible gambling duties. Without a regulated market, demand tends to move to illegal operators that are not bound by those controls.
4. Consumer protection is the third pillar. The law imposes disclosure duties and rules for deposits, withdrawals, and prizes. In an illegal market, the customer is dealing with firms outside the effective reach of national authorities, which makes recovery of funds or compensation harder. For payment providers, that is the familiar problem of the underground market: disputes do not disappear, they just become harder to manage.
5. The fourth and fifth interests are children and adolescents, and sport. The Constitution gives minors absolute priority in the protection of their rights, and the article says that a formal ban is not enough without practical tools such as age verification, access blocking, and continuous monitoring. It also notes that authorized operators are required to report to sports authorities, so the policy choice is not only about betting turnover; it is also about how much visibility the state has over the activity it is trying to control.
