Trouble with AI 'hallucinations' spreads to big law firms
May 23 (Reuters) - Another large law firm was forced to explain itself to a judge this week for submitting a court filing with made-up citations generated by an artificial intelligence chatbot.
Attorneys from Mississippi-founded law firm Butler Snow apologized to U.S. District Judge Anna Manasco in Alabama after they inadvertently included case citations generated by ChatGPT in two court filings.
Butler Snow partner Matthew Reeves said in a Monday filing that he regretted his "lapse in diligence and judgment" for failing to verify the citations.
The 400-lawyer firm, which did not immediately respond to a request for comment, is defending former Alabama Department of Corrections Commissioner Jeff Dunn in an inmate's lawsuit alleging he was repeatedly attacked in prison. Dunn has denied wrongdoing. The judge has not yet said whether she will impose sanctions over the filings.
Jamila Mensah of Norton Rose Fulbright, one of the lawyers representing plaintiff Frankie Johnson, declined to comment.
AI-generated fictions, known as "hallucinations," have cropped up in court filings and landed attorneys in hot water ever since ChatGPT and other generative AI programs became widely available more than two years ago. Courts have sanctioned and admonished attorneys around the country for violating professional rules that require them to vet their work however it is produced.
Many of the cases have involved small law firms or self-represented litigants. But examples of big firms or big companies grappling with AI hallucinations are growing.
Last week a lawyer at law firm Latham & Watkins, which is defending AI company Anthropic in a copyright lawsuit related to music lyrics, apologized to a California federal judge after submitting, opens new tab an expert report that cited an article title invented by AI.
Lawyers for the music publishers suing Anthropic have asked the judge to exclude the report. The judge has not yet ruled on the request.
Earlier this month, a court-appointed special master imposed sanctions, opens new tab and ordered law firm K&L Gates and a smaller firm, Ellis George, to pay $31,100 for what he called a "collective debacle" in which they included inaccurate case citations and quotations stemming from the use of AI in a filing.
Lawyers from the two firms are representing former Los Angeles County District Attorney Jackie Lacey in a dispute with insurance giant State Farm. A spokesperson for K&L Gates and a lawyer at Ellis George did not immediately respond to requests for comment. State Farm and its lawyers at Sheppard Mullin did not immediately respond to similar requests.
The special master, retired judge Michael Wilner, wrote in the order that he had been "affirmatively misled" by the filing. "I read their brief, was persuaded (or at least intrigued) by the authorities that they cited, and looked up the decisions to learn more about them – only to find that they didn't exist," he wrote. "That's scary."
Daniel Linna, a senior lecturer and director of law and technology initiatives at Northwestern's law and engineering schools, said the inclusion of AI-generated fabrications in court briefs is in part a result of a lack of education and training.
Despite the perils, AI also has the potential to increase the quality of legal briefs and improve access to justice, he said.

How Trump is fueling a new gun buying boom with a surprising demographic
A growing number of women are buying guns for the first time, with many crediting Donald Trump 's policies for emboldening them to exercise their Second Amendment rights as others noted their growing fear of the political climate in the U.S. Since the start of 2020, more than 20 million Americans have become first-time gun owners, with women - especially from minority backgrounds - making up a significant share of the spike.

Tiny home builders are targeting fire ravished LA
Modular home builders are targeting Los Angeles fire victims with offers of cheaper and quicker rebuilding options. Large swathes of Los Angeles were destroyed in devastating wildfires earlier this year, which destroyed more than 16,000 structures. Many homeowners who saw their properties burned to the ground were then met with the compounding heartbreak of home insurance payouts that will only cover a fraction of the rebuilding costs. Now businesses such as ICON and Hapi Homes see an opening to mass market their tiny homes, built off-site with the help of 3-D printers and then transported to their final location. Such pre-fabricated homes have long had a reputation for poor quality and unattractive design which the companies hope to dispel. 'Disasters are actually going to be the turning point' for wider adoption of modular housing, Vikas Enti, CEO of Reframe Systems, told the Wall Street Journal. 'That's what we're betting on,' he said of the company's push into disaster zone aftermaths. 'Homeowners in a moment of crisis want to try something different,' Jason Ballard, CEO of ICON, agreed. Ballard told the Journal that his business, which uses technology such as 3-D printers to layer concrete, was inundated with calls following the LA fires. The Texas-based company is now focusing its expansion on areas frequently hit by natural disasters, such as California and Florida. Williams Rebuild, another modular home construction company, is planning to build up to 150 homes a year for fire victims in LA. The Los Angeles Mayor's office is also in discussions with a series of modular builders, the Journal reported. SoLa Impact, an affordable-housing developer based in the city, is supporting proposed legislation in California that would speed up approval for such housing. 'Never let a crisis go to waste,' the company's CEO Martin Muoto told the Journal. Building new homes off-site is often much cheaper because materials can be purchased in bulk and fewer workers are required for less time. For disaster areas, building away from a crowded construction market means businesses can access less busy supply chains. 3-D printers can be used to layer concrete for the house construction After wildfires devastated Maui, Hawaii, in 2023 more than 100 modular companies flooded the building market. Five of those companies were commissioned by the state and nonprofit HomeAid Hawaii to build 450 temporary units for those who had lost their homes. It served as a pivotal moment for the modular housing industry which has struggled to gain such contracts in the past. 'As a public official, I'm now saying, "Hey, we do have alternatives to typical construction,"' Joseph Campos II, deputy director at Hawaii's Department of Human Services said. 'There can be a partnership with traditional construction trades.'
