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.

Event date unknownBrazilMicrosoft text-to-speech (reported)
A professional voice actor sued a São Paulo shopping centre, saying it used the actor's voice without authorisation in a marketing campaign shown on YouTube, and claimed lost earnings and moral damages. The centre answered that the voice was not the actor's but a synthetic voice produced with Microsoft's text-to-speech service, available to the public. According to the legal news site ConJur, a judge of the 18th Civil Court accepted that the voice was produced synthetically and dismissed the claim; on appeal the actor argued that a notarised record attesting to the similarity of the voices had never been assessed. The 6th Private Law Chamber of the São Paulo Court of Justice annulled that judgment for curtailment of the defence, holding that the use of AI does not by itself rule out misuse of third parties' rights, and sent the case back for evidence on how the campaign voice was generated and how similar it is to the actor's. The court docket shows the case back at first instance at the court-expert stage in 2025; no ruling on the merits is reported. Whether the AI voice reproduces the actor's voice is disputed.

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.

19 Mar 2026Event location unknownChatGPT
In a judgment of 30 July 2026, the 2nd Labour Court of Brasília (Regional Labour Court of the 10th Region) upheld the dismissal for cause, on 19 March 2026, of a manager hired in June 2024. The employer said he had used artificial intelligence to falsify photos of orders on the iFood delivery app. A witness told the court she saw him use ChatGPT to alter a photo of an incomplete order, in which two of four soft drinks had been sent, so that it appeared complete, and use it to contest the customer's complaint to iFood support. The judge found this an act of dishonesty and misconduct that broke the trust required of a manager, rejected his claim that the dismissal was fabricated in retaliation for a claim he had filed the day before, dismissed all his claims, denied severance items and ordered him to pay 10% counsel fees, suspended because he was granted free legal aid. The legal news site Migalhas reported the judgment on 3 August 2026. No appeal is reported.

Feb 2026Event location unknownUnidentified image tool
In February 2026 federal deputy Rogério Correia posted on X a realistic image produced with artificial intelligence that, according to the Federal District court, inserted former president Jair Bolsonaro into a nonexistent scene and linked him to the banker Daniel Vorcaro, Banco Master and an alleged illicit scheme. Bolsonaro sued; a first-instance court ordered the deputy in May 2026 to pay 20,000 reais in moral damages and publish a retraction. On 8 October 2026 the First Civil Panel of the Federal District and Territories Court of Justice (TJDFT) unanimously dismissed the deputy's appeal, holding that parliamentary immunity does not cover a realistic AI image of a nonexistent event presented without a clear warning, and that the association harmed Bolsonaro's honour and image. The judgment was made public on 20 October 2026.

2025Event location unknownUnidentified image tool
A civil court in Goiânia, Brazil (32ª Vara Cível) ordered Telegram in a judgment signed on 6 October 2026 to pay R$10,000 in moral damages to a woman whose fake intimate images, created with artificial intelligence, were shared on the platform. According to the judgment as reported by Portal 6 (citing the legal news site Rota Jurídica) and O Popular, Telegram users used AI tools to alter photos that she and her sisters had posted on social media into nude and sexual images, and shared them without consent in a group of more than 120 participants with offensive sexual comments. She reported the group to Telegram through its support channels, including a notification on 29 July 2025, and received no reply; the group had 98 participants then and at least 123 a month later. The court held Telegram liable because it did not remove the posts after notification, ordered removal of the material, measures to block identical or similar copies, and disclosure of data identifying the group's creators and users. Telegram did not contest the case and did not answer O Popular.
