31 Mar 2026 to 11 Sept 2026United StatesIrys (reported)
A Los Angeles County Superior Court judge ordered a senior associate at Musick, Peeler & Garrett, the outside firm defending State Farm in a homeowner's lawsuit over a fire-damaged home, to pay a $999.99 sanction after the associate's motions in limine cited cases, quotations and holdings that did not exist, Law360 reported on 14 September 2026. In a declaration reproduced by Reason's Volokh Conspiracy, the associate said she used an AI program called Irys to prepare the motions, did not check some of the citations, and wrongly believed the program was cite-checked through the firm's Westlaw subscription; she confirmed seven non-existent case citations across eight motions. The plaintiff's lawyers found the citations and raised them at a status conference on 7 August 2026. The firm acknowledged citations that appeared to be AI hallucinations, and its lead trial counsel apologised to the court and the plaintiff. According to Law360, the judge had considered up to $5,000, and the amount set is one cent below the level at which California law requires a court to notify the State Bar.

On 24 April 2026 the Supreme Court of Alabama dismissed an appeal by two siblings in a family dispute over living trusts because their lawyer, W. Perry Hall, had filed briefs in which most of the legal authorities were misquoted or did not exist. The court said they appeared to be AI hallucinations, and at a show-cause hearing in February 2026 Hall admitted that many authorities did not exist and that he had improperly used AI to obtain them. The court ordered Hall to pay the opposing party's fees and costs of $17,200 and double appeal costs, barred him from filing in the court without a co-signing attorney and referred him to the Alabama State Bar. It said the dismissal was imposed as a sanction because of the particularly egregious facts. One justice, concurring in part and dissenting in part, objected to dismissing the appeal as a sanction for the lawyer's conduct but would have affirmed the judgment against the clients on the merits.

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.

19 May 2026United StatesUnidentified voice-cloning tool (suspected)
A married couple in their sixties buying a US$460,000 condo in Hudsonville, near Grand Rapids, Michigan, received an email on 19 May 2026, days before closing, telling them to wire US$66,026.92 for the down payment and closing costs within 24 hours. The email listed a phone number differing from their loan officer's by two digits, and the husband then received a call confirming the instructions in a voice that sounded just like the loan officer. The couple borrowed from family and other sources and wired the money. The day before closing their real loan officer sent the actual statement; the closing was cancelled hours before signing and the money was gone. The husband now believes the call came from a spoofed number using AI-assisted voice cloning; Tyler Adams of CertifID, which is working with the couple and federal officials, said someone's email in the transaction was probably compromised and that the scammers likely cloned the loan officer's voice from social-media clips. The sender's address had two extra letters ('UnitedsMortgages' instead of 'UnitedMortgage'). Neither the lender nor the loan officer is accused of complicity. The couple later completed the purchase in early June from their mutual fund, reported the loss to the FBI's Internet Crime Complaint Center, and describe lasting apprehension and have discussed delaying retirement. CNN reported the case on 15 September 2026; the account the money went to has since closed.
