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.”

The L.A. City Council voted Wednesday to study how large property buyers may be preventing Angelenos from becoming homeowners.

The vote follows a housing department study released in October that found large landlords, like property management companies and investment firms, owned a growing share of L.A. properties.

Rapid property buys by these organizations may lead to residents being displaced and limit opportunities for prospective homebuyers, the report states.

The new study approved this week will attempt to weigh how much added risk large property owners’ businesses are placing on tenants, homeowners and small landlords.

President Donald Trump and Gov. Gavin Newsom have proposed regulating housing purchases by institutional investors — a group of the very largest corporate landlords.

“It’s shameful that we allow private equity firms in Manhattan to become some of the biggest landlords in many of our cities,” Newsom said at his State of the State address in January.

Trump issued an executive order in January to limit institutional investors’ ability to buy single-family homes.

L.A. City Councilmember Monica Rodriguez pushed for both housing department studies, saying she hopes the City Council will use the research to make policy that helps first-time homebuyers and mom-and-pop landlords to build generational wealth.

“Mass consolidation and monopolization” of L.A. housing stock puts the first attempt at home ownership out of reach for many young adults and families, she said at Wednesday’s meeting.

More on the October report

The Los Angeles Housing Department found that corporations and other large organizations owned a growing share of L.A.’s housing stock from 2018 to 2023.

The biggest change in ownership was the large organizations’ share of two- to four-unit buildings in the city, which increased by 29% over the six years studied. The report raised concerns that these organizations are targeting relatively small buildings that are often associated with small landlords.

When it comes to single family-homes, more than 1-in- properties was found to be sold to an organization and not an individual buyer over the six years studied.

The department also noted that there is some evidence behind concerns that “large corporate landlords may be associated with more evictions, more habitability violations, and overall higher levels of housing insecurity for renters.”

The report listed three companies that each agreed to pay out millions of dollars in recent years after facing allegations of unlawful practices as landlords: K3 Holdings, Wedgewood Homes and Invitation Homes.

According to the housing department report, K3 Holdings ranks as having the fastest-growing inventory of properties over the six-year period. The company agreed to pay $2.2 million to settle a lawsuit in 2023 that alleged they illegally targeted long-term Latino residents for displacement from properties in Koreatown and Highland Park.

Wedgewood Homes takes the top spot in flipped L.A. properties, the study found. That company agreed to pay $3.5 million in 2021 after allegations that the company unlawfully evicted and harassed tenants in order to quickly resell homes.

The housing department found Wedgewood Homes sold nearly 400 homes in the six-year period of its study. The company resold 81% of those homes in less than a year at an average price increase of 33%, the study found.

Invitation Homes is one of the largest owners of single-family rentals in the U.S., the report said, and the company agreed to pay $3.7 million to settle a lawsuit over allegations of illegal rent increases for around 1,900 California homes.

K3 Holdings and Wedgewood Homes have previously denied any allegations of wrongdoing, and court documents show Invitation Homes Inc. did not admit or deny liability in the lawsuit against the company.

LAist reached out to all three companies about the report’s findings. They did not immediately provide additional comments.

Other council members weigh in

At the Wednesday meeting, council President Marqueece Harris-Dawson said he appreciated the effort going toward solving this issue.

“When I first took office [in 2015], eight out of every 10 residential units that went up for sale were bought by a corporation,” he said about the area in South L.A. where District 8, 9 and 15 meet.

Harris-Dawson said because the corporations were buying up properties, working people were squeezed out of the housing market in the once-affordable area.

Councilmember Eunisses Hernandez also criticized corporations and large investors.

“Homes that should be places where people put down roots, raise their kids and build generational wealth are increasingly treated like commodities in an investment portfolio,” Hernandez said.

Councilmember John Lee welcomed the study, but said he blames the consolidation on the council’s own policies that make it harder to be a property owner.

“I don’t even know if we need a study,” he said. “I think we understand why there’s more corporatization of ownership in our city. It’s the over restrictive policies of this council.”

Editor’s note: This is part of our “My LA” series — a look at how changing demographics are shifting culture in LA’s historic neighborhoods and communities — told by the people from those communities.

It’s Jan. 11, 2025, and I’m sitting in a restaurant in downtown Los Angeles fighting the overwhelming urge to cry.

I just learned my house survived the Eaton Fire, but I can’t shake the tremor in my friends’ voices who lost theirs. The fire is 15% contained — four days into what would become the second-most destructive fire in California history.

Across from me sits Francisco Sánchez, associate administrator of the U.S. Small Business Administration under President Joe Biden, who oversees the Office of Disaster Recovery and Resilience. Sánchez flew in from Washington, D.C. to see the devastation caused by the Eaton and Palisades fires.

In disaster-response circles, he’s something of a legend. He helped coordinate the rapid conversion of the Houston Astrodome to house families displaced by Hurricane Katrina. But he’s also about to lose his job. The Trump administration is set to take over the federal government in nine days.

I run through the facts about Altadena. One in five residents is Black. One in four is Latino. The median age is 45.

We talk about resiliency and rebuilding. We talk about neighbors banding together to collectively bargain with contractors. We talk about the Army Corps of Engineers choosing not to conduct soil testing in Altadena — the first time it has declined to do so after a major fire in two decades.

But it’s the last thing Sánchez tells me that stays with me a year later.

“You have to fight like hell to make sure what happened in Hawaii doesn’t happen to you,” he said. “They will turn Altadena into condos, if you let them.”

Firefighters battling a blaze in Altadena

Breathing was difficult

In the spring, the calls began.

Neighbors scattered across Los Angeles County started receiving offers from real estate agents and private equity firms that had quietly moved into the region.

Before the fire, private acquisitions accounted for about 5% of home sales in Altadena. Four months later, they accounted for nearly 50%.

What Sánchez warned about was already happening. Breathing was still difficult on my block.

The Eaton Fire began as a wildfire but quickly became an urban fire. The Los Angeles Times compared the toxicity levels in our area to New York City after the Sept. 11 attacks.

I worried about neighbors — mostly people of color — whose homes survived but who had little choice but to return quickly because they lacked sufficient insurance coverage.

I worried about the air we were breathing. But no one seemed able to tell me who was responsible for monitoring it.

At the disaster center on Woodbury Road, sympathetic county officials told me the state of California oversaw air quality. I called my state senator, Sen. Sasha Renée Pérez.

Pérez, a newly elected Democrat and former mayor, took my calls — and those of my neighbors — seriously. She contacted the governor’s office and spoke with the team responsible for air quality in Altadena.

The response she received was: “It’s complicated.” That might have been the understatement of the year.

Moments of grace

Months passed.

It became heartbreaking to watch Altadena residents leave LA altogether because they couldn’t afford to live anywhere else in the city. It was even harder to watch my neighbor across the street sell his home after placing an “Altadena Is Not for Sale” sign on his lawn.

Still, amid the devastation, there were moments of grace.

Volunteers from across Los Angeles flooded the greater Pasadena area to help after the fire. Residents leaned on the Federal Emergency Management Agency (FEMA), mutual aid networks, family members, local churches and the Los Angeles Fire Department Foundation. 

I volunteered at — and relied on — community donation centers myself. One of the most meaningful was the Pasadena Community Job Center, which served the region’s undocumented population.

Even though my home didn’t burn, I had to evacuate after high levels of lead were detected inside.

From wherever I was staying, I drove an hour to attend town halls, join community meetings, ask questions at disaster centers and speak with elected officials.

Nearly half of Altadena — an unincorporated foothill community long known for its diversity and working-class stability — had burned.

Firefighters battle to save a home

Only one firetruck

Months later, Sánchez called again.

He was no longer a federal employee, but he still checked in on me and my neighbors. He suggested I attend a Crisis Management Academy at Hayes Boone in downtown LA, where he sat on the board.

I pulled my suit from a vacuum-sealed remediation bag and went.

By chance, I sat next to Rick Crawford, the emergency and crisis management coordinator for the U.S. Capitol and Supreme Court and a former battalion chief with the Los Angeles Fire Department.

I told him I lived west of Lake Avenue — historically the predominantly Black, Latino and working-class side of Altadena.

Nineteen of the 20 deaths from the Eaton Fire occurred there and only one firetruck was initially sent to that side of town.

Evacuation notices arrived hours later than they did in wealthier neighborhoods east of Lake Avenue — if they arrived at all. My family never received one.

I asked Crawford if he believed racism explained the disparity. He told me something worse might have happened.

The night before the fires, he said, officials knew a severe wind event was coming. Yet staffing levels were not increased.

“Business as usual,” he called it.

When the Palisades Fire ignited, city resources were quickly stretched. The city turned to the county for help. When the Eaton Fire exploded, the county deployed the firefighters it had left to protect Altadena.

By the time flames reached west of Lake Avenue, resources were gone.

A failure of preparation turned into a failure of response — one that hit my side of Altadena hardest.

The Fair Oaks Burger restaurant became a community rallying point

The sounds of construction

One year later, Altadena is still waiting.

Friends who lost their homes are waiting for settlements from Southern California Edison Co., which investigators believe caused the Eaton Fire, to determine whether they can rebuild at all.

Trial is scheduled for January 2027. A judge recently ordered Edison to produce witnesses when called, criticizing attempts to prolong the discovery process for attorneys representing fire victims. A grand jury is also considering whether to indict the utility company in connection with the 19 deaths in Altadena.

Those of us who have returned do what we can to support one another — and the small businesses trying to survive.

In those days, my business meetings happened at Miya, Unincorporated Coffee or Fair Oaks Burger.

Community advocates — including Altadena for Accountability and Altadena Rising, along with Pérez — pushed the California Department of Justice to open a civil rights investigation into the evacuation response in West Altadena.

Walking along Altadena Drive, I thought about the homes and gardens that had once lined the street.

Reconstruction has begun, slowly. The sound of construction — loud, constant — is an inconvenience. But it’s better than the eerie silence that followed the fire.

On Mariposa Street, I passed the empty space where Amara Kitchen and Altadena Hardware had once stood.

Next door, something new appeared. Betsy, the restaurant from chef Tyler Wells — who also lost his home in the fire — was drawing diners from across LA for its live-fire cooking.

It lifted my spirits to see people coming to Altadena again. But as a local resident, I still struggled to get a reservation.

Maybe that was the first glimpse of what rebuilding might look like: those with money and privilege dining easily, while the rest of us remain on the waiting list.

The rebuild is slow. The pain is enormous. But the resilience of Altadena is fierce.

We fight for accountability, truth and justice. We fight for the right to rebuild our town as it once was. Most of all, we fight for one another.

Because, as labor leader Mary Harris “Mother” Jones once said: “Pray for the dead, and fight like hell for the living.”

The U.S. military said on Friday that all six crew members were killed when a KC-135 refueling aircraft went down in Iraq, raising the death toll after two weeks of war with Iran.

The U.S. Central Command (CENTCOM), which oversees the Middle East, reported an unspecified incident involving two aircraft Thursday. It said the U.S. KC-135 refueling aircraft was lost in western Iraq, while the other landed safely. It is investigating the circumstances but confirmed the "loss of the aircraft was not due to hostile fire or friendly fire."

The news came as President Trump and his defense secretary touted success in the U.S.-Israeli war with Iran but complained about negative media coverage of Operation Epic Fury.

Defense Secretary Pete Hegseth said Friday that joint U.S.-Israeli military strikes have hit more than 15,000 targets and injured the new Iranian supreme leader.

President Trump, in a post on Truth Social, said the U.S. is "totally destroying" Iran's regime, militarily and economically.

Late Thursday, Israeli Prime Minister Benjamin Netanyahu said Israel had weakened Iran's rulers, but it may not be enough to topple them — the Iranian people would have to do that.

Iranian and Lebanese health officials and Israeli authorities reported more than 1,300 people killed in Iran, 773 people in Lebanon and 12 civilians in Israel, as well as two Israeli soldiers killed in Lebanon. Wednesday's aircraft crash over Iraq brings the U.S. military death toll to 13, seven of whom were killed in combat. Eight U.S. service members are severely injured, according to the Pentagon.

The humanitarian toll also deepened as the total number of people displaced by the fighting in Iran and Lebanon reached into the millions.

Here are further updates about the conflict.

Officials brace for an end without a deal — and the risk of a "war routine"

A senior official in the region, speaking on condition of anonymity because they were not authorized to discuss internal deliberations, told NPR they expected the war to last at least another week, and that Israeli leaders increasingly believe the U.S. and Israel will end the war unilaterally, without a negotiated agreement. In such a scenario, the official said, Iran and allied groups, including the Lebanese militant group Hezbollah and Houthi rebels in Yemen, could establish a new normal of intermittent fire at Israel, prompting repeated Israeli retaliation.

The official said that kind of tit-for-tat exchange would leave Israelis living with an intolerable "war routine" even if the intensity of the conflict fades.

The official also said Israel is not ruling out an expanded ground operation in southern Lebanon, but described Israel as holding back so far from striking broad civilian infrastructure, largely because the U.S. sees Lebanon as a partner.

Israel expands strikes in Iran and hits Hezbollah targets in Lebanon

Israel's air force said Friday it struck more than 200 targets over the past day in western and central Iran, including ballistic missile launchers, air defense systems and weapons manufacturing sites.

The military said the strikes included simultaneous strikes in Tehran, Shiraz and Ahvaz. They targeted regime infrastructure, including an underground site used to produce and store ballistic missiles, as well as a central air-defense base.

In Lebanon, Israel said it hit Hezbollah command centers in the country's south and in central Beirut.

A senior official in the region, speaking on condition of anonymity because they were not authorized to speak publicly, said the strike on Beirut's bustling Bachura neighborhood, located near the prime minister's office, was symbolic, and meant to send a message that Israel will not tolerate Hezbollah's fire much longer.

Lebanon's president, Joseph Aoun, has called for direct talks with Israel to end the bombing. Israel has not responded publicly on the matter.

The Israeli military also said it struck the Al-Zrariya Bridge over the Litani River, describing it as a key crossing used by Hezbollah fighters and an area from which launchers had been positioned.

Iran and Hezbollah attacks hit Israel overnight; dozens treated for minor injuries

An Iranian ballistic missile in the northern Israeli town of Zarzir left dozens lightly wounded, according to Israel's emergency services organization, Magen David Adom.

One person was reported to be in moderate condition and was being treated after being hit with shrapnel. Another 57 people were being treated for minor injuries, mostly from glass shards.

Hezbollah also continued firing into northern Israel overnight, and Israel's military said its air defense and strike operations were responding across both fronts.

U.S. temporarily eases Russian oil sanctions for cargoes already at sea

The Trump administration issued a temporary authorization allowing countries to purchase Russian oil already stranded at sea. It argued the move is a narrowly tailored step to stabilize energy markets.

In a post on X, Treasury Secretary Scott Bessent said the measure applies only to oil "already in transit" and will not provide significant financial benefit to Russia.

In a statement published last week, a number of top Senate Democrats warned such a move would weaken sanctions and benefit Russia as energy prices rise.

French soldier killed in attack in Iraq

French President Emmanuel Macron said Friday a French soldier was killed in an attack in the Irbil region of Iraq that left several other French soldiers wounded.

Macron called the attack "unacceptable" and said the war in Iran cannot justify strikes on forces deployed in Iraq as part of the fight against ISIS.

Since the start of the war with Iran, the French president has underlined his concerns about international law not being respected, but also deployed several naval vessels to the Eastern Mediterranean, near Cyprus, to protect French military bases and citizens in the region. French officials have insisted it is a defensive, rather than an offensive mission.
