1 May 2021BrazilUnidentified death-record matching system
A Brazilian federal judge in the 4th federal region ordered the social security institute (INSS) to pay a retiree R$3,917.67 in moral damages after finding that his pension had been stopped by a failure of the institute's artificial intelligence system, according to a Federal Regional Court of the 4th Region (TRF4) news item relayed by the Brazilian Institute of Social Security Law on 30 September 2022. The judge explained that the benefit was suspended automatically on 1 May 2021 by an artificial intelligence command that captured data from the death-records system (Sisobi), and that the data used, the person's name and mother's name, were not enough to prevent the wrongful cessation. The retiree said the pension was his only source of income; he asked for reactivation and sent a handwritten declaration, and although he showed in person that he was alive, the benefit was restored only in January 2022. The judge wrote that the AI 'proved inefficient or unintelligent' in this case and that the INSS made him wait 226 days. Arrears were also ordered paid. Whether the INSS appealed is not reported.

2024Event location unknownGemini (reported)
A civil court in Niterói, Rio de Janeiro state, ordered Google Brasil to pay a businessman R$20,000 in moral damages in a sentence dated 12 May 2025. The judge found it undisputed that the company's artificial intelligence had pointed to him in searches as the owner of a gambling platform called 7 Games, with which he had no connection, as the company register showed. The court found that the false information damaged his reputation: he was being held responsible for scams on the betting platform and received threats by email from its customers. The court had earlier granted an injunction to remove the association, and the sentence confirmed it. Google argued that it does not host the material shown in its results and only organises pages available on the web; the judge held Google responsible because the information came from its own platform rather than from a linked page. Conjur, a legal-news site, identifies the tool as Gemini and reports that the association began after an interview in which he recommended seven games; the sentence names no product. Whether Google appealed is not reported.

30 Apr 2024BraziliFood facial recognition check
A delivery worker in Brazil's Federal District who had worked for the iFood app for about three years says he was banned from the platform in April 2024 shortly after completing the app's daily facial recognition check. iFood support told him another person had tried to access his account; when he asked to see that person's photos, they were his own. G1 reports that the only difference from his registration photo was his hair, which he was growing out. In a judgment reported in June 2025, a Brasília labour judge, applying a default because iFood had not filed a defence in time, accepted as true that the contract was suspended through iFood's fault, that he suffered financial and psychological losses, and that the facial recognition tool had a racist failure, and ordered iFood to pay R$60,000 in moral damages. iFood denies that its facial recognition procedure analyses racial characteristics and has appealed. The account was restored during the case. No appeal ruling has been reported.

13 Apr 2024BrazilUnidentified facial recognition system
During the half-time interval of the Sergipe state football championship final at the Batistão stadium in Aracaju on 13 April 2024, military police took a personal trainer from the stands to a police room after the stadium's facial recognition system flagged him as a man with an open arrest warrant; he was searched and questioned and released once police confirmed he was not the person sought (G1, his lawyer and the military police). Sergipe's governor publicly regretted 'the failure of the facial recognition tool' and suspended its use until a new protocol was adopted. In June 2024 the man sued the state for 550,000 reais in moral damages; the state argued that the Aracaju municipality, not the state, had contracted the system. In December 2025 the judge rejected that preliminary objection, according to Mangue Jornalismo, which read the court file. No final judgment is reported.

Oct 2026BrazilUnidentified AI drafting tool (suspected)
Goiânia city councillor Aava Santiago (PSB) told Brazil's National Council of Justice (CNJ) that the final text of a judgment of the Regional Electoral Court of Goiás (TRE-GO), which removed her from office for party infidelity, contained commands, instructions and review records indicating the use of artificial intelligence without the human supervision that CNJ Resolution 615/2025 requires. On 9 October 2026, the day a substitute took her seat, the national inspector of justice, Minister Benedito Gonçalves, found the allegations plausible on a preliminary reading, suspended the judgment and the administrative acts that followed from it, and gave the court 15 days to explain its review procedures, G1 and Jurinews report. The suspension does not review the merits of the removal, and whether AI was used irregularly has yet to be investigated.

Folha Vitória reported on 29 September 2026, citing the Espírito Santo Civil Police, that a 39-year-old man was arrested on 28 September on a preventive warrant after an inquiry into qualified theft by electronic fraud against an 81-year-old man in the north-west of the state. According to the police, the suspect, who worked as a security guard at a dance venue, invited the man to his home on the pretext of making a free-entry card, kept his bank card, obtained personal data and photographed his face. The police say he used the images to get past the facial recognition of the banking app and enable access to the account on his own phone, then reset security passwords, redeemed investments and made Pix transfers without the victim's knowledge, diverting R$6,080. The victim is described as illiterate. The police say the suspect had prior records and was serving a sentence under a progressive regime. Folha do ES and Tribuna Norte Leste carried the same police account but could not be read.

Feb 2025Event location unknownMeu INSS app
In February (2025, inferred from the article date) a retirement claim filed through Brazil's Meu INSS social security app for a former sugarcane worker in northeast Brazil was rejected. Rest of World reported that the request was turned down because the system identified the claimant as a man. The claimant, who has chronic illnesses, is quoted saying the benefit is still denied despite complete documents, and Rest of World reports that minor errors in earlier claims through the app had led to numerous rejections. The retirement claim was approved in March after INSS directors corrected the mistake, which the claimant attributed to a contact at an agricultural workers' confederation. The INSS states that automated decisions follow specified legal criteria.

The Espírito Santo Civil Police (Defa, the fraud and forgery unit) said a 27-year-old man was arrested on a warrant in Serra on 22 September 2026, suspected of defrauding a personal trainer of more than R$100,000. According to the police, the suspect offered a car in exchange for the victim's motorcycle; during the negotiation he persuaded the victim to perform a facial-recognition procedure, saying it was needed to transfer the car's ownership; the biometric was later used to contract a vehicle financing in the victim's name without his authorisation, and weeks after the exchange the victim discovered that the car he had received did not belong to the suspect and was a rental. The loss, combining the motorcycle and the fraudulently contracted financing, exceeded R$100,000. The suspect, who police say had been arrested in São Paulo in July 2025 in a 'love scam' case, was taken to the Centro de Triagem at the Rodrigo Figueiredo da Rosa prison complex and remains at the disposal of the courts. The financing provider and the facial-recognition system are not identified, and the reports do not say how the captured biometric was used to pass the financing.

A court released him on 13 August under precautionary measures; no charges had been filed as of mid-September. OpenAI did not give police ChatGPT’s replies.
