Brazil's Superior Court of Justice (STJ) on Wednesday (Sept. 9) upheld a limit on back payments to claimants who sue the INSS, the national social security institute, to obtain or revise benefits. In the same session, the court set rules for benefits granted automatically by software systems. The ruling closed a set of clarification appeals in repetitive case 1,124, decided without floor debate, in a block vote that followed the rapporteur, Justice Paulo Sérgio Domingues.

According to Folha de S.Paulo, the justices held that a claimant who goes to court before exhausting the administrative process with the social security agency can lose part of the back payments and, in some situations, even the right to the benefit. The rule covers retirement pensions, survivor benefits, sickness and accident benefits, maternity pay and the BPC, a continuous benefit for low-income elderly and disabled people. The core change is the starting date of back payments: they now count from the moment the claimant filed suit, or from the date the INSS was formally summoned in the case, instead of from the date of the original administrative claim.

How the case got here

The original binding thesis was fixed in November 2025 by the STJ's First Section, according to IEPREV, a social security law institute that took part in the case as amicus curiae and published the full thesis. Under those rules, an administrative claim must come with minimal documentation; a request without it, which the court called a forced denial, can be rejected outright, and the claimant then lacks standing to sue. Anyone wishing to present new documents or facts must first file a new claim with the INSS, based on case 350 of the Supreme Federal Court (STF), decided in 2014. If the INSS receives a valid but poorly documented claim and fails to ask the claimant to complete the file, standing is preserved. Installments older than the five years before the lawsuit are barred by the statute of limitations.

The clarification appeals, requests to clear up points of a ruling, were filed by IBDP, the Brazilian Social Security Law Institute, in an attempt to improve payment conditions for claimants. Lawyer Jane Berwanger, of the institute, argues that STF case 350 allows claimants to go straight to court, bypassing the social security agency, in specific situations, such as when the INSS rejects the claim. She also challenged automatic denials: according to the lawyer, quoted by Jornal do Comércio, an audit by the TCU, the federal accounts court, found that 2.2 million claims received an automatic decision in 2023, a rise of 70 percent, with no human review.

In the vote adopted by the court, the rapporteur kept automatic granting in place. In his view, the INSS may continue awarding benefits through software, but whenever documents are needed to confirm entitlement, the claimant must be told how to present them, by the system or by a civil servant, and there can be no automatic denial.

With the appeals closed, the thesis of case 1,124 remains valid and binding on courts across Brazil. The ruling will still be published in the official gazette, and individual cases on the matter will be decided under the rules now confirmed.
