How to use AI but steer clear of hallucinated cases; ABA Journal, July 15, 2026

 DAVID WEISENFELD , ABA Journal; How to use AI but steer clear of hallucinated cases

"f you ask lawyers for their best advice on using artificial intelligence in their practices, some will suggest it be avoided at all costs. But despite the many news stories about attorneys getting caught citing hallucinated cases in court filings, there are ways to use the technology cautiously and wisely, lawyers and technologists tell the ABA Journal...

Don't use general-purpose chatbots for caselaw research. Tools like ChatGPT and Anthropic’s Claude generate text by probability, so they produce citations that look real without knowing whether the case exists. They mimic the shape of a citation, not its substance. For research, use tools grounded in actual legal databases. Now the frontier models like ChatGPT are getting better at avoiding fake cases. But regardless, they should never be relied upon.”

Penalties stack up as AI spreads through the legal system; NPR, April 3, 2026

Martin Kaste, NPR; Penalties stack up as AI spreads through the legal system

""Recently we had 10 cases from 10 different courts on a single day," says Damien Charlotin, a researcher at the business school HEC Paris who keeps a worldwide tally of instances of courts sanctioning people for using erroneous information generated by AI...

The numbers started taking off last year, and Charlotin says the rate is still increasing. He counts a total of more than 1,200 to date, of which about 800 are from U.S. courts.

Penalties are also on the rise, he says. A federal court may have set a record last month with an order for a lawyer in Oregon to pay $109,700 in sanctions and costs for filing AI-generated errors.

The professional embarrassments even take place at the level of state supreme courts...

"I am surprised that people are still doing this when it's been in the news," says Carla Wale, associate dean of information & technology and director of the law library at the University of Washington School of Law. She's designing special training in AI ethics for students who are interested. But she also says the ethical rules aren't completely settled...

When lawyers get in trouble for using AI, it's because they've violated the long-standing rule that holds them responsible for the accuracy of their filings, regardless of how they were generated."

  Santul Nerkar, The New York Times; A.I. ‘Hallucinations’ Created Errors in Court Filing, Top Law Firm Says

Sullivan & Cromwell apologized for submitting a court document that had fake citations created by artificial intelligence.

"An elite Wall Street law firm has apologized to a federal judge for submitting a court filing replete with errors created by artificial intelligence, including “hallucinations” that fabricated case citations.

The A.I.-generated errors came in a recent motion in U.S. Bankruptcy Court in Manhattan and were discovered by lawyers from an opposing firm, Andrew Dietderich, a partner at Sullivan & Cromwell, wrote in a letter to Judge Martin Glenn on April 18."

Lawyer sets new standard for abuse of AI; judge tosses case; Ars Technica, February 6, 2026

 ASHLEY BELANGER , Ars Technica; Lawyer sets new standard for abuse of AI; judge tosses case

"Frustrated by fake citations and flowery prose packed with “out-of-left-field” references to ancient libraries and Ray Bradbury’s Fahrenheit 451, a New York federal judge took the rare step of terminating a case this week due to a lawyer’s repeated misuse of AI when drafting filings.

In an order on Thursday, District Judge Katherine Polk Failla ruled that the extraordinary sanctions were warranted after an attorney, Steven Feldman, kept responding to requests to correct his filings with documents containing fake citations."
