3 Jun 2026United StatesUnidentified AI tool
On 3 June 2026 the US Court of Appeals for the Ninth Circuit fined immigration attorneys Mike Singh Sethi and William Rounds $2,500 each and suspended both from practice before the court for six months. Briefs filed in an asylum petition for review cited two cases that do not exist and attributed quotations to opinions that do not contain them. In a motion to correct, the attorneys called the errors typographical, and at oral argument Rounds twice said AI was not used. In their response to the court's order to show cause, they conceded that the errors were probably the product of unauthorised AI use by the firm's unlicensed brief writers and a failure to check citations. The court said the suspension was owed to their repeated failure of candour. The Board of Immigration Appeals then suspended Sethi from practice before the Board, the immigration courts and the Department of Homeland Security for six months, effective 13 June 2026, and designated that decision as a precedent on 1 October 2026.

A judge of the 5th Mixed Court of Sousa, Paraíba, found hidden instructions aimed at artificial intelligence tools spread over seven pages of a lawyer's motion for clarification in a public-competition case in June 2026, including an order to ignore impartiality and a note calling it a test of whether the judge used only AI to decide. The judge fined the lawyer two penalties of R$16,400 (R$32,800 in total) for bad-faith litigation and contempt of the court's dignity, and referred the case to the Paraíba bar (OAB-PB) and the state prosecutors, G1 reports. The defence said the commands were not inserted deliberately and blamed an error in exporting a file prepared with AI support. An appeal judge refused to suspend the fines on 30 June, the trial judge kept them on reconsideration, and in July, G1 reports, the OAB-PB preventively suspended two lawyers after opening procedures into two hidden-command cases, one of them the Sousa case.

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.

10 Jul 2026ChileUnidentified image tool
Teletrece reported on 3 October 2026 that on 10 July 2026 female students at a secondary school in Puente Alto, Chile, found fake sexual images of themselves and other students on a classmate's phone. Families say the images were made with AI tools from ordinary photos the girls had posted on Instagram, that four students took part in obtaining, editing and circulating them, and that the material reached other students. Some of the girls had panic attacks, according to their parents. The school suspended the students identified as responsible for 15 days; after their return, parents say, they mocked the girls, a fight followed, and a parent accuses the father of one of the students involved of threats and of loitering near the school, after which she says they filed reports with the PDI. The Superintendencia de Educación confirmed a formal investigation of the school.
