The Brief

A Los Angeles-area attorney must pay a $10,000 fine for filing a state court appeal full of fake quotations generated by the artificial intelligence tool ChatGPT.

The fine appears to be the largest issued over AI fabrications by a California court and came with a blistering opinion stating that 21 of 23 quotes from cases cited in the attorney’s opening brief were made up. It also noted that numerous out-of-state and federal courts have confronted attorneys for citing fake legal authority.

“We therefore publish this opinion as a warning,” it continued. “Simply stated, no brief, pleading, motion, or any other paper filed in any court should contain any citations— whether provided by generative AI or any other source—that the attorney responsible for submitting the pleading has not personally read and verified.”

The opinion, issued 10 days ago in California’s 2nd District Court of Appeal, is a clear example of why the state’s legal authorities are scrambling to regulate the use of AI in the judiciary. The state’s Judicial Council two weeks ago issued guidelines requiring judges and court staff to either ban generative AI or adopt a generative AI use policy by Dec. 15. Meanwhile, the California Bar Association is considering whether to strengthen its code of conduct to account for various forms of AI following a request by the California Supreme Court last month.

The attorney fined last week, Amir Mostafavi, told the court that he did not read text generated by the AI model before submitting the appeal in July 2023, months after OpenAI marketed ChatGPT as capable of passing the bar exam. A three-judge panel fined him for filing a frivolous appeal, violating court rules, citing fake cases, and wasting the court’s time and the taxpayers money, according to the opinion.

Mostafavi told CalMatters he wrote the appeal and then used ChatGPT to try and improve it. He said that he didn’t know it would add case citations or make things up.

He thinks it is unrealistic to expect lawyers to stop using AI. It’s become an important tool just as online databases largely replaced law libraries and, until AI systems stop hallucinating fake information, he suggests lawyers who use AI to proceed with caution.

“In the meantime we’re going to have some victims, we’re going to have some damages, we’re going to have some wreckages,” he said. “I hope this example will help others not fall into the hole. I’m paying the price.”

The fine issued to Mostafavi is the most costly penalty issued to an attorney by a California state court and one of the highest fines ever issued over attorney use of AI, according to Damien Charlotin, who teaches a class on AI and the law at a business school in Paris. He tracks instances of attorneys citing fake cases, primarily in Australia, Canada, the United States, and the United Kingdom.

In a widely-publicized case in May, a U.S. district court judge in California ordered two law firms to pay $31,100 in fees to defense counsel and the court for costs associated with using “bogus AI-generated research.” In that ruling, the judge described feeling misled, said they almost cited fake material in a judicial order and said “Strong deterrence is needed to make sure that attorneys don’t succumb to this easy shortcut.”

Charlotin thinks courts and the public should expect to see an exponential rise in these cases in the future. When he started tracking court filings involving AI and fake cases earlier this year, he encountered a few cases a month. Now he sees a few cases a day. Large language models confidently state falsehoods as facts, particularly when there are no supporting facts.

“The harder your legal argument is to make, the more the model will tend to hallucinate, because they will try to please you,” he said. “That’s where the confirmation bias kicks in.”

A May 2024 analysis by Stanford University’s RegLab found that although three out of four lawyers plan to use generative AI in their practice, some forms of AI generate hallucinations in one out of three queries. Detecting fake material cited in legal filings could get harder as models grow in size.

Another tracker of cases where lawyers cite nonexistent legal authority due to use of AI identifies 52 such cases in California and more than 600 nationwide. That amount is expected to increase in the near future because AI innovation is outpacing the education of attorneys, said Nicholas Sanctis, a law student at Capital University Law School in Ohio.

Jenny Wondracek, who leads the tracker project, said she expects this trend to get worse because she still regularly encounters lawyers who don’t know that AI makes things up or believe that legal tech tools can eliminate all fake or false material generated by language models.

“I think we’d see a reduction if (lawyers) just understood the basics of the technology,” she said.

Like Charlotin, she suspects there are more instances of made up cases generated by AI in state court filings than in federal courts, but a lack of standard filing methods makes it difficult to verify that. She said she encounters fake cases most often among overburdened attorneys or people who choose to represent themselves in family court.

She suspects the number of arguments filed by attorneys that use AI and cite fake cases will continue to go up, but added that not just attorneys engage in the practice. In recent weeks, she’s documented three instances of judges citing fake legal authority in their decisions.

As California considers how to treat generative AI and fake case citations, Wondracek said they can consider approaches taken by other states, such as temporary suspensions, requiring attorneys who get caught to take courses to better understand how to ethically use AI, or requiring them to teach law students how they can avoid making the same mistake.

Mark McKenna, codirector of the UCLA Institute of Technology, Law & Policy praised fines like the one against Mostafavi as punishing lawyers for “an abdication of your responsibility as a party representing someone.” He thinks the problem “will get worse before it gets better,” because there’s been a rush among law schools and private firms to adopt AI without thinking through the appropriate way to use them.

UCLA School of Law professor Andrew Selbst agrees, pointing out that clerks that work for judges are recent law school graduates, and students are getting bombarded with the message that they must use AI or get left behind. Educators and other professionals report feeling similar pressures.

“This is getting shoved down all our throats,” he said. “It’s being pushed in firms and schools and a lot of places and we have not yet grappled with the consequences of that.”

Some government funding streams for L.A. County’s public health system are drying up, and officials are turning to private philanthropy to fill the gap.

A new privately funded foundation launched Thursday to strengthen public health services after $50 million in federal, state and local funding cuts to the county’s Department of Public Health since early last year.

“It is really a hard day for our community when we have to ask for private donations to fund a public good, but unfortunately, we've lost too much money to not take this important step,” said Public Health Director Barbara Ferrer.

In February, the county’s Public Health Department closed seven clinics, with six remaining open. About half of the patients seen in those clinics are uninsured, according to county officials. The department also cut hundreds of staff positions.

Ferrer is on the board of the new foundation, The Fund for Advancing Public Health LA, which held its first meeting Thursday.

She said the fund will help the county maintain its basic public health infrastructure, including disease prevention, health promotion, environmental health, and emergency response efforts.

Other board members include several health insurance executives, as well as actors Sean Penn and Danny Trejo. Board member Saree Kayne of the R&S Kayne Foundation pledged $150,000 to the fund Thursday. Kayne said she hopes the donation encourages others to give.

The foundation aims to raise $2 million this year.

More cuts expected

L.A. County Supervisor Holly Mitchell said it’s crucial to have an alternative funding stream to protect services for the county's most vulnerable residents.

“We are saving public health,” Mitchell said. “This fund represents a new approach, one that brings together government philanthropy in the private sector to invest in community-based solutions, protect vulnerable populations, and strengthen our public health infrastructure.”

Officials say more public health cuts are coming, through the federal budget law known as the "Big Beautiful Bill," which slashes funding for Medi-Cal.

The county Department of Public Health anticipates losing up to $300 million in revenue over the next three years because of the federal budget bill and other potential funding freezes. Federal funding accounts for almost 50% of the public health budget, according to county officials.

Mitchell also led an effort to put a half-percent county sales tax increase to fund public health on the June ballot.

If approved by voters, that proposal, known as Measure ER, is expected to raise about $1 billion a year for county safety net health services, including about $100 million for the public health department.

The Rose Bowl in Pasadena may be a centenarian, but it’s holding up pretty well as it continues to host events on its way to a starring role in the LA28 Olympics.

But before it can host the soccer final, it needs fixes, especially to the infrastructure serving the bathrooms and drinking fountains. Fears of a toilet backup while in the world’s spotlight led Rep. Laura Friedman to seek federal funds for upgrades. On Thursday she announced she secured just over $1 million.

“Two years from now, athletes around the world are going to compete for gold right where we are standing. This is not the time to find out whether or not these pipes are up to the task,” Friedman said.

The planned work, she added, will lead to improved water flow capacity and water drainage, eliminating the risk of backups and emergency maintenance.

The funds came from the House of Representatives Interior and Environment subcommittee. The fixes, an official said, will be completed by the LA28 Olympics.

The funds, however, are a drop in the bucket when it comes to what’s needed to make needed improvements to the Pasadena venue.

“Over the  next 20 years there's about $200 million that we need to put in and that's everything from updating light fixtures to updating gas, water, wastewater lines, etc.,” said Dedan Brozino,  president of the Rose Bowl Legacy Foundation, the nonprofit that supports the Rose Bowl stadium's preservation and enhancement.

Getting venues ready will be expensive

The money is a much-needed win at a time when elected officials in city, county, state and federal offices have been struggling to find the funds to get L.A.-area venues ready for the global Olympic stage in two years.

A $360 million proposal to spruce up asphalt in parking lots around Exposition Park won’t be done in time for the Olympics, as originally planned. Meanwhile, just up the street, there’s concern that a $2.6 billion expansion of the L.A. Convention Center, which is hosting Olympic wrestling, fencing and judo in 2028 won’t be ready for the Olympics.

Additionally, to save money, LA28 organizers moved Olympic diving to the Rose Bowl complex last year because it has two Olympic-sized pools, while the Exposition Park complex doesn't and would need expensive upgrades.

About the chick: The chick hatched March 14. The zoo opened its Cape vulture enclosure in February 2025 after years of planning to encourage the birds to roost and nest, welcoming a new breeding pair that year. When it grows to be an adult, it’ll have a wingspan of 8 1/2 feet.

About the enclosure: The L.A. Zoo said it spent years developing the vulture habitat, which was designed to mimic the vultures’ natural environment in South Africa and nearby countries. Dominick Dorsa II, the zoo’s director of animal care, said in a statement the successful hatching is “a testament to the design and construction” of the habitat.

How to see the chick: You can’t for the time being. Zoo officials are keeping it away from visitors until the chick matures, though you can still see adult Cape vultures at the zoo’s enclosure.

Though visitors will have to wait until the chick matures to see it in the enclosure, you can still take in the impressive eight and a half foot wingspan of the adult Cape vultures.

What zoo officials are saying: “Welcoming a Cape vulture chick is a thrilling moment for our team and a beacon of hope for African vultures,” the L.A. Zoo’s curator of birds Rose Legato said in a statement. “Vultures are one of nature's most misunderstood marvels, and I cannot wait for our guests to eventually watch this chick grow and learn just how vital they are to our ecosystems.”

About the species: Cape vultures are listed as a vulnerable species due to human activities and encroachment. According to the L.A. Zoo, African vultures are more closely related to eagles and hawks than vultures native to the Americas, like the zoo's California condors that hatched last year.

What should have been a celebration for formerly incarcerated youth completing a reentry program at the Boyle Heights Arts Conservatory (BHAC) last week instead ended with seven students and two staff members detained by the Los Angeles Police Department, according to witnesses. 

Now, nearly a week later, BHAC staff and city officials are demanding answers from the LAPD, with some accusing officers of racial profiling. 

According to the LAPD, officers observed a large group gathered on the corner of Cesar E. Chavez Avenue and Mott Street around 4:16 p.m. on March 26. Authorities then requested backup for what they described as “a large group surrounding officers,” LAPD Public Information Officer Tony Im said. 

The group, classified by police as an “aggressive gang group,” consisted of seven 18-year-old students from the BHAC’s Bridge Academy Movement (BAM) program and two BHAC staff members.

The BAM program pays formerly incarcerated youth to complete 200-250 hours in media and visual arts training to prepare them for creative careers. That day, students were set to showcase their work at the BAM program graduation for families and community members. 

Rene Weber, a teaching artist at the BHAC, had been with the students setting up for the ceremony minutes before the incident occurred. 

According to Weber, the students had gone to coffee across the street at Milpa Kitchen as they often did, when staff were alerted that they were being detained. 

Weber said he arrived to find students and a staff member pressed against the wall in handcuffs. 

Video from the scene, taken by a staff member at the BHAC, shows multiple officers surrounding the group. At one point, an officer orders a person to “get on the wall” and displays a stun gun.  

“No, none of that, these are kids right here,” the staff member replies.

Another staff member, Teotl Veliz, recorded a large police response.  

“I counted 12 cop cars, that’s at least 25 cops, and they had a helicopter,” Veliz said. “It was just so comedic, tragically comedic, that it was on their graduation day too.”

Officers established a perimeter with yellow tape along the side of Ashley’s Beauty Salon as local business owners and witnesses gathered around the students. 

“I was just incredibly disappointed in LAPD… because it became so apparent to everybody, all at the same time, that it was racial profiling and nothing else,” Veliz said.

Weber said officers gave shifting explanations for the stop at the scene, including blocking the sidewalk and possible underage vaping. After Weber told the officers that all of the students were 18, they said they would investigate whether the group had any gang affiliation. 

Police have not responded to questions about what led officers to believe that the group was gang-affiliated. 

Weber recalled pleading with the officers to let the group go and explaining to them that they worked across the street. Community members and local business owners also stepped in to vouch for the students. 

“Our job is to help them gain a new perspective on life,” Weber said. “They’re coming out of juvenile detention and they’re turning their lives around. We can do our part in keeping them off the streets and keeping them doing better but what does it mean if they’re going to be profiled and treated exactly the same way?” 

In total, seven 18-year-old students and two staff members were detained. BHAC staff said one student and one staff member were taken to Hollenbeck Community Police Station and released less than two hours later after advocacy from community members and Councilmember Ysabel Jurado.

The incident ultimately resulted in an infraction for smoking a cannabis e-vape on a public sidewalk, according to a photo of the infraction shared with the Beat. LAPD did not provide details about the people taken to Hollenbeck Station or the infraction. 

The graduation ceremony was cancelled that night and is expected to be rescheduled in April. 

“Graduation should be a moment of pride and possibility — not fear,” Jurado said in a statement. “I’m seeking answers about what occurred, and this underscores the need for stronger relationships between law enforcement and community organizations so moments like these are protected, not disrupted.”

Carmelita Ramirez‑Sanchez, the conservatory’s executive director, said she was grateful to the community and Jurado for advocating for the students’ release. Jurado met her at Hollenbeck Station within 20 minutes of being alerted to the incident, she said. 

“They had store owners, señoras, barbers, that ran out and were trying to explain to the police who our kids were,” Ramirez‑Sanchez said. 

Still, she said the incident tarnished what should have been a joyous celebration.

“I imagine that what this does is derail this entire idea that you can be an active participant in your own restorative growth,” she said.
