California Judges Test AI Court Assistant Without Telling Litigants When It Reviews Their Cases

Date:

Two of California’s largest trial courts are testing an artificial intelligence tool that can help draft judicial orders and produce research memos, raising questions about transparency, accuracy and whether litigants should know when AI is being used in cases that affect them.

So far, judges have used the technology mostly in civil matters. But records obtained by CalMatters show the tool could eventually be tested in criminal proceedings, where decisions can affect a person’s freedom and access to justice.

The Los Angeles County Superior Court began a pilot program in February using software developed by Learned Hand, a company founded by Shlomo Klapper. The Riverside County Superior Court also has a $10,000 agreement with the company to test the program, mostly for civil and probate research memos that assist judges in decision-making.

Learned Hand uses large language models from Anthropic, OpenAI and Google to function as a virtual AI assistant for judges. The company says it tests the technology for bias and accuracy, though it has not publicly released those results.

In Los Angeles County, the Superior Court’s contract is worth about $314,000 and includes a roadmap for possible testing in criminal, family and probate divisions. Court officials did not provide CalMatters with detailed criteria for deciding whether the tool could safely be expanded into criminal and family courts, where the stakes are often far higher than in routine civil disputes.

One Los Angeles County Superior Court judge, who spoke to CalMatters on condition of anonymity because of judicial conduct rules, said the possibility of using the technology in sensitive criminal matters was alarming. The judge said colleagues discussed during a recent lunch that the tool could one day be used to help review appeals from people who argue that racial bias affected their conviction or sentence. California courts have seen a surge in such claims since lawmakers passed the Racial Justice Act in 2020.

“I find it outrageous,” the judge said. “AI cannot and will never replace human judgment when it comes to evaluating complex social dynamics. Ultimately, this will erode public confidence in the competence and fairness of the judiciary.”

Documents obtained through public records requests show most California superior courts now have policies governing generative AI. The state Judicial Council required courts to adopt such policies before using the technology. Of the 51 courts that responded to CalMatters, about a dozen said they use AI tools from companies including LexisNexis, Thomson Reuters and Microsoft Copilot.

The use of AI in courtrooms remains controversial because large language models can generate false citations, misleading summaries and overly confident conclusions. A 2025 MIT study found that models from major companies, including Google and Anthropic, can reduce critical thinking and brain activity.

AI-generated errors already have appeared in legal proceedings. Researcher Damien Charlotin has documented hundreds of instances in which litigants, attorneys and judges made mistakes after relying on AI, including nearly 90 cases in California-based state or federal courts since August 2024.

Last fall, a Los Angeles attorney was fined $10,000 for citing nonexistent cases. Earlier this month, The Sacramento Bee reported that AI use led to errors in four cases handled by prosecutors in Nevada County. Most documented examples involve attorneys or self-represented litigants, but UCLA law professors have warned that judges are likely to make more AI-related mistakes in the future. In recent months, the U.S. Senate examined apparent AI use by federal judges in Mississippi and New Jersey after rulings included significant factual errors.

Klapper, who previously worked as a law clerk for a federal appeals court and for the surveillance technology company Palantir, said courts need AI to reduce backlogs and operate more efficiently.

“Could we hire more staff?” he told CalMatters. “Maybe, but it won’t be enough to keep up with the exponential growth that is coming, or to adequately solve the current crisis. I think the only solution is to assign every judge and attorney their own AI assistant.”

Klapper said his goal is to combine the strengths of human judges with the capabilities of machines. He acknowledged that AI systems may contain bias but argued that models can be tested in ways humans cannot.

“I’m not saying all machines are free of bias,” he said. “I’m not even saying my machine is free of bias. What I’m saying is that we can test it, and people have tested it. That’s the advantage over humans.”

The generative AI policies for the Los Angeles and Riverside superior courts require disclosure only when a motion, ruling or other document is drafted entirely with generative AI.

Both courts declined to say whether litigants are being told that the tool is being tested in connection with their cases. A Los Angeles County Superior Court spokesperson told CalMatters the testing involves motions that have already been decided and is being done separately from active cases. However, the contract allows testing in live cases.

“Even with successful evaluation and extensive testing, the Court would still be several months, if not years, away from implementing this type of tool,” the spokesperson said.

The Los Angeles County contract permits the tool to be tested on two important types of criminal motions: suppression motions, which determine what evidence prosecutors may present at trial, and post-conviction relief motions, filed by people who have already been convicted and are seeking another chance at release.

Los Angeles County District Attorney Nathan Hochman said those provisions are his “biggest concern.” After reviewing the contract, he described the two categories as “incredibly important motions in the criminal justice system.”

“When you’re dealing with a person’s liberty — unlike the civil arena, which covers everything else — the stakes are of the highest importance,” Hochman said. “I don’t want to take the risk, especially in a criminal case, that AI gets it wrong. That someone’s constitutional rights are violated. That someone goes to prison wrongly or, on the other hand, that someone gets away with something.”

In Los Angeles, some judges learned more about the Learned Hand contract during a March presentation by Superior Court Judges Yvette Verastegui and Olivia Rosales, who oversee the criminal division. As part of an annual tour, the judges visit courthouses throughout the county to brief judges on court operations, caseloads and other issues. During a lunch, Verastegui and Rosales indicated the tool might someday be used to assist with Racial Justice Act petitions, according to a judge who attended.

The California Racial Justice Act allows people to challenge a criminal conviction or sentence if they believe racial bias played a role. People incarcerated in state prisons file petitions directly with the court. If a petition appears to have merit, the process can include appointment of counsel, legal briefing and evidentiary hearings before a judge decides whether to grant relief.

A tool such as Learned Hand could change that process. According to the judge who attended the lunch, Verastegui and Rosales said the software could generate proposed decisions for judges to consider when deciding whether to deny petitions or allow them to proceed to later stages.

“My concern, of course, is that courts will use that as an anchor and cling to that initial analysis,” the judge said. “It is an extremely dangerous path. Setting aside inaccuracy, which will be a major concern, it dehumanizes the entire process. It does not treat people as individuals with lived experiences. It essentially reimposes a one-size-fits-all model of justice.”

A second Los Angeles County Superior Court judge, who also spoke anonymously, recalled the presentation and said they would not trust or use the tool to summarize a Racial Justice Act petition.

AI can reproduce or intensify patterns found in the data used to build a model, including human bias. Large language models have shown racial and gender bias. Previous reviews of predictive policing technology used by the Los Angeles Police Department found racial bias, and an analysis of the COMPAS risk assessment algorithm found it was more likely to label Black people as at risk of reoffending after incarceration than white people with similar records.

Public defenders who spoke with CalMatters shared those concerns.

Elizabeth Lashley-Haynes, a deputy public defender in the Los Angeles County Public Defender’s Office, said it would be “extremely problematic and bordering on unethical” for a judge to use such a tool to review Racial Justice Act petitions, which she described as highly complex.

“They are unlike anything that has ever been done before in the legal system,” said Lashley-Haynes, who specializes in Racial Justice Act cases. “The words used in these cases, which have racial connotations or meanings, are far beyond the scope of anything artificial intelligence can do.”

In interviews with CalMatters, Klapper and Los Angeles County Superior Court Executive Officer David Slayton denied that the court has plans to use the tool for Racial Justice Act petitions. A court spokesperson later confirmed by email that the contract allows the tool to be used that way, but said that has not yet occurred.

Klapper said that if a Racial Justice Act module were developed, the tool would need to be evaluated for possible bias and built jointly with the court.

“The timing is very sensitive, right?” he said. “It’s a very delicate decision, I’m not going to lie. The stakes are high; I understand why people could be very concerned. Especially when it comes to criminal matters, I have even more hesitation and more caution than usual, because fundamental rights are at stake.”

In Los Angeles, six Superior Court judges and their research attorneys are using Learned Hand primarily for research, motion summaries and help drafting tentative rulings, according to Slayton. He said the tool will not be expanded beyond the civil division “until court leadership is comfortable.”

“The court is being very prudent and careful in its use of this type of technology,” Slayton said. “Until we evaluate it and determine that it is effective in those areas, we will not expand it to others.”

Slayton said the tool will be reviewed quarterly to determine how it might be used in the future, though he did not give specifics about the evaluation. A court spokesperson later told CalMatters by email that Learned Hand is judged by the same standards applied to law clerks and research attorneys: accurate legal research, sound analysis, neutral judicial writing and reliable work that supports judicial decision-making.

Los Angeles County Superior Court Judge Samantha Jessner, who chairs the court’s Judicial Technology Advisory Committee, said she did not know until recently that the tool might be used outside the civil division. She said judges are not involved in contract negotiations because of ethical restrictions.

“I think we have a duty and an obligation to explore whether artificial intelligence has a place in our work as a judiciary, and that is exactly what this pilot program is for,” Jessner said.

The Riverside County Superior Court signed its agreement with Learned Hand in February. Emails obtained by CalMatters show Klapper suggested to Riverside court executives Jason Galkin and Sarah Hodgson that the court begin with a common civil motion, then expand quickly once the tool was established. He suggested Hodgson prepare a list of motions and workflows that create the most difficulty, citing the Racial Justice Act as an example.

About two weeks later, Hodgson described the most labor-intensive motions as those “trying to drive us into retirement,” including discovery motions and attorney fee motions. For criminal matters, the court suggested Klapper focus on document-heavy issues, including death penalty habeas corpus petitions and probation revocations.

Since Riverside’s pilot began, seven civil and probate attorneys have had access to the tool. Galkin, the court’s executive officer, said the court is evaluating the product to understand what it can do. He said the tool is not being used to draft tentative rulings.

“We don’t even know whether expansion is likely, so there are no established criteria for what that expansion would look like or thresholds for it,” Galkin said. “Right now, the fundamental question is: Does this help staff and assist them in achieving their professional goals?”

As courts continue testing AI, attorneys such as Hochman say its use may be inevitable, but should be limited to routine, repetitive and lower-level tasks.

“It’s the analysis of the case itself, along with the conclusions that would be reached, that makes me very distrustful of AI right now,” Hochman said. “A large part of that is because I don’t know all the data it is using to make its decision. The one thing I am completely certain of is that AI did not go to law school.”

‘I felt like I wasn’t learning’: Community college students struggle with online education

A close-up shot of a person wearing a black dress working on a laptop on a small table next to the window of a restaurant, with sunlight lighting up half of their face. In the foreground, out of focus, is the back of the laptop as the person types on the keyboard.

In summary

About 40% of California’s community college courses are online now, redefining education. These courses are more accessible, college officials say, but they come with serious drawbacks.

California’s community colleges represent the largest higher education system in the country — more than 2 million students, or 60 times the undergraduate population of UC Berkeley. But walking around a community college campus, it’s often hard to tell. 

Since the COVID-19 pandemic, cafeterias and local coffee shops are quieter, fewer students are sitting on the quad and, with less foot traffic, the grass is lush. Even after campuses returned to in-person classes, many students are still working from their dining room table: About 40% of all community college classes are online, according to Melissa Villarin, a spokesperson for the California Community Colleges Chancellor’s Office. 

The state’s community colleges are funded based largely on the number of students they enroll, and since students prefer online courses, there’s an incentive for schools to expand them.

Ask students or professors about the merits of online education, and they’ll often say it’s more accessible, especially for students who have kids or are working a full-time job. The same argument is often true at the University of California and California State University campuses, which offer considerably more online courses than before the pandemic, though far fewer than the community colleges. 

Ask students or professors about the problems of online education, and they’ll point to any number of familiar complaints: a lack of engagement, a sense of loneliness, impersonal lectures, and the temptation to move the Zoom window aside and click on something else. In online classrooms where the majority of students keep their cameras off, bots and scammers have become a systemwide problem: they use AI and other algorithms to mimic real students, submit assignments and steal financial aid. Even real students are using AI to submit online assignments, while teachers are using it to grade.

Researchers say it’s hard to know how the quality of online education compares to in-person courses because it’s subjective and because of the wide diversity of courses and  teaching methods. 

In Lupe Archundia’s microeconomics class at San Joaquin Delta College in Stockton, all the lectures were pre-recorded, in some cases more than a decade ago. The professor gives students the answers to the quizzes — before they take the test — and all the quizzes are in a multiple-choice format that a computer grades. 

“I am a 39-year old woman,” Archundia said. “It’s not like I just finished high school and I want easy test answers.”

Archundia has two kids and a full-time job as a secretary, so she studies in the evenings, turning her dining room table into a standing desk with the help of a few cardboard boxes. She wants a bachelor’s degree to help her move up in her career.

In the beginning of the course, she said she would study for three hours before completing each quiz, but once she discovered the professor had made the answers available, she started cutting corners. She said there are still certain concepts, such as elasticity, that she doesn’t fully understand, even though she aced the online exam. 

She feels conflicted about it. “I’m responsible, too,” she said. 

What the research does — or doesn’t — say

The research into online education is generally inconclusive. One 2025 study found that students consistently perform worse in online classes than in-person ones, though the gap is decreasing. Online courses also make it easier for students to hold a job while in school and complete their degree in the long term, said Di Xu, a professor at UC Irvine’s School of Education. 

When asked about students’ concerns with online education, Alex Breitler, a spokesperson for Delta College, said these classes expand “access to higher education for working adults, parents, caregivers, and other students balancing significant responsibilities,” including many students who “simply would not be able to pursue college without online options.”

Delta is not alone — the idea that online courses increase access is a common refrain among college officials. Xu pointed to one empirical study of an online master’s program at Georgia Tech that proved this point, though the  students are very different from those at California’s community colleges, where many are seeking short-term career training or an associate degree.

What researchers do know is that online education has inherent challenges. It requires “self-directed learning skills,” including a “very high level of self-time management,” said Xu. “In an in-person environment interaction happens naturally,” she said. “But in an online environment, especially asynchronous, that opportunity needs to be embedded. Otherwise, the student will feel very lonely.” 

The majority of online classes at California’s community colleges are asynchronous, meaning that the content is all pre-recorded and students can study at their own convenience. Students prefer asynchronous classes too, even compared to online courses where the instructor is live,  according to a survey by the RP Group, an education research nonprofit.

Archundia said she always opts for in-person classes but there are few available, especially for the English classes she wants to take and during the evening hours that she’s available. Her dream is to become a writer, and she wants to switch her major to English, instead of her current major, business administration, though she isn’t sure what classes are necessary to make that happen. 

In April, when she reached out to a college counselor for help selecting classes, the next available appointment was about three weeks later. Archundia still hasn’t been able to find an appointment that works with her work schedule.

One-on-one advising and support structures, such as guidance counselors, are essential for online students, said Rebecca Ruan-O’Shaughnessy, the director of program and strategy at College Futures Foundation and a former executive at the California Community Colleges Chancellor’s Office — but schools also need to adapt. 

Online courses are fundamentally different, and schools need to redesign their courses, not just retrofit them, she said. She pointed to some programs that have new and promising approaches to online education, such as shortening the length of the class or trying to integrate adults’ work experience given so many online students have a full-time job. 

“That is the difficult part for community colleges and other institutions,” Ruan-O’Shaughnessy said. “Frankly, they don’t have the incentive to do that level of work, because that’s a lot of work.”

Breitler, with Delta College, acknowledged that counseling appointments are often booked “weeks in advance” because of high demand. He said the college is trying new solutions, such as letting students submit questions to counselors online and creating drop-in hours where an appointment isn’t needed. 

Remedial education in foreign languages

Cyndi Cunningham enrolled at Palomar College in San Marcos, on the northern edge of San Diego County, in 2022, after the pandemic forced her local shopping mall to close temporarily, making her longtime retail job suddenly seem precarious. Starting college for the first time, she was taking general education and introductory courses, mostly online, and struggled to pay attention and manage her time. “I only ended up taking one class in person per semester — not because I didn’t want to take in-person classes — but because I couldn’t find them,” she said. “I felt like I wasn’t learning; I was just kind of doing tasks.”

She saw professors cutting corners too: Two of her classes in Chicano Studies were taught by the same professor and she once noticed he was using the exact same lecture in both classes. 

Cunningham has since transferred from community college to Cal State San Marcos, where she’s majoring in ethnic studies and plans to become a high school teacher. “Even engaging with other students is so much different in person than on a discussion board,” she said. “I realized more how much of a disservice the online classes did.”

To an extent, online classes can save costs for colleges because they don’t require a physical space and they can enroll many more students, said Xu. But she said adding support systems — such as specialized counseling for students or professional development for faculty — can create additional expenses. Online education “has the potential to save a lot of cost,” she said, but only if colleges are “willing to sacrifice a lot of the quality elements that are important for students.” 

Foreign language courses are particularly costly for universities, said Julia Simon, a professor of French at UC Davis and the chair of a task force on languages for the university. Language courses are typically small, meet regularly, and many less popular languages enroll only a handful of students. Facing a structural budget deficit, the university recently asked her task force to develop a plan for slashing courses in the event of cuts. 

Meanwhile, she said both the nearby community colleges and the UC system are expanding online foreign language classes, which can operate at a larger scale. Sacramento City College, for instance, is offering four French classes in fall 2026 — all of them are online and fully asynchronous. 

“It’s an enormous problem,” she said. In her view, the students who take online courses lack the same opportunities to practice their speaking and miss out on vital cultural lessons that don’t fit in a strict language-learning curriculum. Once they enter UC Davis, they’re unprepared, she said. “We can’t make them repeat courses they’ve already had.” 

She said she’s considering creating a set of conversation classes that would amount to remedial education. 

‘It all depends on the professor’

California legislators and education officials have poured millions into improving online education since the pandemic and have introduced new rules meant to encourage more interaction between faculty and students. All across the state, faculty routinely train on ways to improve their online instruction, and colleges have hired staff members to help with online course design and scheduling.

But the 2024 survey by the RP Group found that among faculty who had taught at least one online course, the majority still preferred in-person instruction. 

Tina Rocha’s creative writing professor at San Joaquin Delta College recently took a sabbatical, learning how to improve teaching for people with learning disabilities. It paid off, said Rocha, who is 55 and started college in 2024 after recovering from three back-to-back strokes in 2020. Because of her disability, she occasionally needs reminders from the instructor to submit assignments. Sometimes she asks for accommodations to avoid certain noises or lights that distort her vision and make her twitch, she said, but her professor is understanding and accommodating. Online education can be a “wonderful alternative,” she said.

Rocha studies every night at her dining room table, which is often scattered with her notebooks.  A calendar hangs from her wall, with notes covering every corner of white space, and a white board sits at the entrance to her home, listing out in color-coded lines each of the week’s responsibilities. 

“It all depends on the professor,” she said. Her online film class this semester has been much worse than her creative writing course, she said. The film professor has a lava lamp in the background that reflects psychedelic patterns on the ceiling. When Rocha asked him to turn it off, he said he tried but was unable to, without offering an explanation. Now, to prevent symptoms, she places a sticky note on the screen whenever the professor starts talking. 

Rocha said she tried to switch to an in-person film class but was too late. Only online classes were available.

A small fix could make a big difference in Tijuana River pollution: When will it happen?

Water flows across a narrow rural road lined with dense trees and brush. A yellow road sign showing a horseback rider stands near the bend in the road, while sunlight filters through the foliage and reflects off the shallow water covering the pavement.

In summary

As the U.S. and Mexico pursue $800 million in upgrades to wastewater facilities on the border, local officials are working on a smaller fix to improve conditions as soon as next year.

Communities living with one of the most severe pollution problems in California could see immediate relief if San Diego leaders can get a key Tijuana River project out of the gate. 

While millions of gallons of untreated sewage enter the river on a regular basis, one road crossing, known as the Saturn Boulevard hot spot, is the source of most airborne pollution from the river. 

As the U.S. and Mexico pursue a combined $800 million in upgrades to wastewater facilities on both sides of the border, local governments are working on a smaller fix to that chokepoint that could improve conditions as soon as next year, officials said.

San Diego leaders are trying to secure about $25 million to repair the road crossing at Saturn Boulevard, where sewage-tainted water is forced through outdated culverts that spew hydrogen sulfide gas and other toxins throughout south San Diego.

Fixing the hot spot can “mitigate the turbulence in that area, which will mitigate the emissions that basically rocket aerosols into the air,” said San Diego County Supervisor Paloma Aguirre, who has spearheaded efforts to clean up the river.

But they’re still trying to nail down a funding source for the project. 

Sewage pollution from the cross-border river has plagued Imperial Beach, Coronado and other parts of southern San Diego for decades. The threat rose as the Tijuana population grew and wastewater plants on both sides of the border failed, spilling hundreds of millions of gallons of raw sewage into the ocean in recent years.

San Diegans have long known that raw sewage in the ocean is a hazard to swimmers and surfers, and local beaches have been closed for years. Then in 2024, researchers with UC San Diego Scripps Institution of Oceanography discovered that the pollution wasn’t just fouling the water. It was also contaminating the air. 

The river emits airborne chemicals including hydrogen sulfide gas, which cause respiratory problems and other ailments among people in neighboring communities. 

Residents experience asthma, stomach problems, skin rashes and headaches, even without going in the water. Parents are wary about letting children play outside. Local schools enforce “rainy day schedules” to keep students inside when air quality worsens.

Researchers traced the air pollution to the Saturn Boulevard hot spot. It’s a culvert set along a rural road near the Tijuana River. The structure, which includes several large concrete pipes, was built decades ago to divert flood waters from neighboring farm fields. When it rains, water trickles across the road and gushes through the pipes, creating mounds of foam and spraying contaminants into the air.

San Diego County officials are trying to secure money to fix that. They estimate it will cost about $25 million to re-engineer the site in order to control the flow of floodwater and prevent it from releasing toxic gas and airborne particles.

There are several parallel tracks to funding the project, but none of them is certain.

One is a pot of money in Proposition 4, the $10 billion climate bond measure that California voters approved in 2024. It includes about $50 million for border projects on the Tijuana River in San Diego and New River in Imperial County. 

Although it passed two years ago, the funds haven’t been released because of administrative procedures that slowed their disbursement. This year state Sen. David Alvarez, a San Diego Democrat, introduced legislation to waive some red tape and speed up funding through the bond measure. 

With the money now available, the State Water Resources Board will accept grant applications for the funds this summer between June and August, and then score and award them by early next year, said Jennifer Toney, a senior engineer with the State Water Resources Control Board. Local governments and nonprofits working on those rivers are eligible to apply.

The board could award up to $20 million for construction such as the Saturn Boulevard project, Conty said. But it faces competition from other possible Tijuana River efforts such as sediment removal, trash capture and others, as well as proposed projects on the New River, Toney said.

On a separate track, state lawmakers have submitted a request in this year’s state budget for $23 million to cover most of the Saturn Boulevard construction. If that’s approved it could free bond money for other border river projects.

A third possible funding source is a proposed half-cent county sales tax, entitled  “Protect San Diego County Health and Safety Act,”  which goes to voters in November. It could generate $360 million per year, with about $80 million of that earmarked for Tijuana River improvements. 

The measure calls for up to 22.5% of tax revenue to be spent on environmental mitigation to address “the toxic sewage crisis in the Tijuana Valley.” But it doesn’t spell out specific projects such as the Saturn Boulevard site, KPBS reported.

In the meantime, an even quicker temporary solution expected to cost $2.5 million could be in place by this time next year. The temporary fix will extend the existing pipes and transfer the flowing water downstream through an enclosed system, County Public Works Director Marisa Barrie stated in an email to CalMatters. That will reduce the churn that causes pollutants to become aerosolized.

“The team evaluated infrastructure mitigation options at the Saturn Boulevard hot spot and agreed to move forward with a short-term solution that will offer tangible immediate benefits,” Barrie stated.

Design, environmental analysis, and permitting for that project is in the works now, Barrie said. It should take about three months to construct, and county officials hope to complete it by March, 2027, before nesting season for birds in the area. 

Aguirre cautioned that reengineering the culvert won’t clean up the river, but will reduce its impact on neighboring communities. “That’s not the permanent solution to the entire crisis. This is something that’s within our power to tackle, working with the state, city and county of San Diego, that we know based on empirical evidence will bring some relief to residents of affected areas.”

No shame: A last-minute election guide for undecided CA voters

With just a week until Election Day and only 8% of ballots returned so far, millions of California voters are still making up their minds about the election. But here at CalMatters, we listen, we don’t judge — so we have a last-minute voter guide to catch you up on what you need to know, such as:

Who’s ahead in the polls?

The latest Democratic Party poll shows Republican Steve Hilton and Democrat Xavier Becerra leading with 22% and 21% respectively, and Tom Steyer in third at 15%.

What’s an open primary and why do we have it?

California’s open primary allows the two candidates who receive the most votes to move on to the general election in November, no matter what party they belong to. The state adopted this system after voters approved Proposition 14 in 2010, which allows voters to pick any candidate in a primary, regardless of their own party affiliation. 

This system allows two candidates from the same political party to potentially advance, which is a real possibility this year because of the sheer number of candidates running for governor and the fact that there’s no clear frontrunner.

Is it too late to vote by mail?

Mailed ballots must be postmarked on or before Election Day and received by election offices within seven days. To make sure your ballot is counted, it’s best to mail your ballot at least five days before June 2, or Thursday.

How can I vote on Election Day?

Besides mailing it in, you can submit your ballot at a drop-off location or vote in-person at the polls from 7 a.m. to 8 p.m. Find your nearest polling place here and your closest ballot drop-off location here.

Check out our last-minute voter guide here. And for more comprehensive info, read CalMatters’ full voter guide, which has the lowdown on other statewide offices, state legislative races and congressional elections, as well as a governor Q&A with the leading candidates.


We’re bringing our voter guide to life through VotingMatters events across California this month, in collaboration with on-the-ground partners: Local news organizations, colleges and nonprofits. Our next event is this evening in Merced and Fresno and Wednesday in Modesto. Plus, we have a DIY kit to host your own event.



Worst threat at Garden Grove chemical tank is over, officials say

The most catastrophic threat from a chemical emergency that forced 50,000 Orange County residents from their homes has passed, fire officials said Monday — but risks and questions remain.

  • Craig Covey, Orange County Fire Authority division chief, in a statement: “The tank has released its pressure. Additionally to that, the temperature has been stabilized and actually reducing. … That is incredibly positive news as we turn the corner on this incident.”

Crews continue to monitor a cracked and damaged 34,000-gallon tank at the GKN Aerospace facility in Garden Grove, after the company first reported a vapor release last week. Gov. Gavin Newsom declared a state of emergency in Orange County, and President Donald Trump signed a federal emergency declaration after Newsom requested federal assistance. 

Meanwhile, Orange County District Attorney Todd Spitzer opened a criminal investigation, deployed drones to survey the site and ordered GKN Aerospace to preserve its records against potential litigation. At least one couple who was evacuated is suing the company for negligence. 

CA courts are putting AI to work. Any objection?

Two of California’s largest courts are experimenting with a new artificial intelligence tool and considering whether it can be used in high-stakes criminal cases.

So far, superior courts in Los Angeles and Riverside counties are primarily using the tool made by the company Learned Hand for civil cases. It can help research attorneys draft orders and write research memos.

  • Samantha Jessner, L.A. County superior court judge: “I think we have a duty and obligation to explore whether or not there is a place for artificial intelligence in what we do as a judicial branch and that’s exactly what this pilot is intended to afford us the opportunity to do.”

But CalMatters’ Cayla Mihalovich and Khari Johnson report today that use of AI in courts has been controversial because of the propensity of AI models to cite falsehoods and to produce sycophantic text. They also learned that L.A. judges floated using the tool to evaluate appeals from people who believe their conviction or sentence was tainted by racial bias.
