California’s challenge of the Trump administration’s military deployment in Los Angeles returned to a federal courtroom in San Francisco on Friday for a brief hearing after an appeals court handed President Donald Trump a key procedural win.

U.S. District Judge Charles Breyer put off issuing any additional rulings and instead asked for briefings from both sides by noon Monday on whether the Posse Comitatus Act, which prohibits troops from conducting civilian law enforcement on U.S. soil, is being violated in Los Angeles.

The hearing happened the day after the 9th Circuit appellate panel allowed the president to keep control of National Guard troops he deployed in response to protests over immigration raids.

California Gov. Gavin Newsom said in his complaint that “violation of the Posse Comitatus Act is imminent, if not already underway” but Breyer last week postponed considering that allegation.

Vice President JD Vance, a Marine veteran, traveled to Los Angeles on Friday and met with troops, including U.S. Marines who have been deployed to protect federal buildings.

According to Vance, the court determined Trump’s determination to send in federal troops “was legitimate” and he will do it again if necessary.

“The president has a very simple proposal to everybody in every city, every community, every town whether big or small, if you enforce your own laws and if you protect federal law enforcement, we’re not going to send in the National Guard because it’s unnecessary,” Vance told journalists after touring a federal complex in Los Angeles.

Vance’s tour of a multiagency Federal Joint Operations Center and a mobile command center came as demonstrations have calmed after sometimes-violent clashes between protesters and police and outbreaks of vandalism and break-ins that followed immigration raids across Southern California earlier this month. Tens of thousands have also marched peacefully in Los Angeles since June 8.

National Guard troops have been accompanying federal agents on some immigration raids, and Marines briefly detained a man on the first day they deployed to protect a federal building. The marked the first time federal troops detained a civilian since deploying to the nation’s second-largest city.

Breyer found Trump acted illegally when, over opposition from California’s governor, the president activated the soldiers. However, the appellate decision halted the judge’s temporary restraining order. Breyer asked the lawyers on Friday to address whether he or the appellate court retains primary jurisdiction to grant an injunction under the Posse Comitatus Act.

California has sought a preliminary injunction giving Newsom back control of the troops in Los Angeles, where protests have calmed down in recent days.

Trump, a Republican, argued that the troops have been necessary to restore order. Newsom, a Democrat, said their presence on the streets of a U.S. city inflamed tensions, usurped local authority and wasted resources.

The demonstrations appear to be winding down, although dozens of protesters showed up Thursday at Dodger Stadium, where a group of federal agents gathered at a parking lot with their faces covered, traveling in SUVs and cargo vans. The Los Angeles Dodgers organization asked them to leave, and they did.

On Tuesday, Los Angeles Mayor Karen Bass lifted a downtown curfew that was first imposed in response to vandalism and clashes with police after crowds gathered in opposition to agents taking migrants into detention.

Trump federalized members of the California National Guard under an authority known as Title 10.

Title 10 allows the president to call the National Guard into federal service when the country “is invaded,” when “there is a rebellion or danger of a rebellion against the authority of the Government,” or when the president is otherwise unable “to execute the laws of the United States.”

Breyer found that Trump had overstepped his legal authority, which he said allows presidents to control state National Guard troops only during times of “rebellion or danger of a rebellion.”

“The protests in Los Angeles fall far short of ‘rebellion,’ ” wrote Breyer, a Watergate prosecutor who was appointed by President Bill Clinton and is the brother of retired Supreme Court Justice Stephen Breyer.

The Trump administration argued that courts can’t second-guess the president’s decisions. The appellate panel ruled otherwise, saying presidents don’t have unfettered power to seize control of a state’s guard, but the panel said that by citing violent acts by protesters in this case, the Trump administration had presented enough evidence to show it had a defensible rationale for federalizing the troops.

For now, the California National Guard will stay in federal hands as the lawsuit proceeds. It is the first deployment by a president of a state National Guard without the governor’s permission since troops were sent to protect Civil Rights Movement marchers in 1965.

Trump celebrated the appellate ruling in a social media post, calling it a “BIG WIN” and hinting at more potential deployments.

Newsom, for his part, has also warned that California won’t be the last state to see troops in the streets if Trump gets his way.

A panel of three federal appellate judges has ruled that a Louisiana law requiring the Ten Commandments to be posted in each of the state’s public school classrooms is unconstitutional.

The ruling Friday marked a major win for civil liberties groups who say the mandate violates the separation of church and state, and that the poster-sized displays would isolate students — especially those who are not Christian.

The mandate has been touted by Republicans, including President Donald Trump, and marks one of the latest pushes by conservatives to incorporate religion into classrooms. Backers of the law argue the Ten Commandments belong in classrooms because they are historical and part of the foundation of U.S. law.

“This is a resounding victory for the separation of church and state and public education,” said Heather L. Weaver, a senior staff attorney with the American Civil Liberties Union. “With today’s ruling, the Fifth Circuit has held Louisiana accountable to a core constitutional promise: Public schools are not Sunday schools, and they must welcome all students, regardless of faith.”

The plaintiffs’ attorneys and Louisiana disagreed on whether the appeals court’s decision applied to every public school district in the state or only the districts party to the lawsuit.

“All school districts in the state are bound to comply with the U.S. Constitution,” said Liz Hayes, a spokesperson for Americans United for Separation of Church and State, which served as co-counsel for the plaintiffs.

The appeals court’s rulings “interpret the law for all of Louisiana,” Hayes added. “Thus, all school districts must abide by this decision and should not post the Ten Commandments in their classrooms.”

Louisiana Attorney General Liz Murrill said she disagreed and believed the ruling only applied to school districts in the five parishes that were party to the lawsuit. Murrill added that she would appeal the ruling, including taking it to the U.S. Supreme Court if necessary.

The panel of judges reviewing the case was unusually liberal for the 5th U.S. Circuit Court of Appeals. In a court with more than twice as many Republican-appointed judges, two of the three judges involved in the ruling were appointed by Democratic presidents.

The court’s ruling stems from a lawsuit filed last year by parents of Louisiana school children from various religious backgrounds, who said the law violates First Amendment language guaranteeing religious liberty and forbidding government establishment of religion.

The ruling also backs an order issued last fall by U.S. District Judge John deGravelles, who declared the mandate unconstitutional and ordered state education officials not to enforce it and to notify all local school boards in the state of his decision.

Republican Gov. Jeff Landry signed the mandate into law last June.

Landry said in a statement Friday that he supports the attorney general’s plans to appeal.

“The Ten Commandments are the foundation of our laws — serving both an educational and historical purpose in our classrooms,” Landry said.

Law experts have long said they expect the Louisiana case to make its way to the U.S. Supreme Court, testing the court on the issue of religion and government.

Similar laws have been challenged in court.

A group of Arkansas families filed a federal lawsuit earlier this month challenging a near-identical law passed in their state. And comparable legislation in Texas currently awaits Gov. Greg Abbott’s signature.

In 1980, the U.S. Supreme Court ruled that a Kentucky law violated the Establishment Clause of the U.S. Constitution, which says Congress can “make no law respecting an establishment of religion.” The court found that the law had no secular purpose but served a plainly religious purpose.

And in 2005, the Supreme Court held that such displays in a pair of Kentucky courthouses violated the Constitution. At the same time, the court upheld a Ten Commandments marker on the grounds of the Texas state Capitol in Austin.

A judge blocked New York City’s mayor from letting federal immigration authorities reopen an office at the city’s main jail, in part because of concerns the mayor invited them back in as part of a deal with the Trump administration to end his corruption case.

New York Judge Mary Rosado’s decision Friday is a setback for Democratic Mayor Eric Adams, who issued an executive order permitting U.S. Immigration and Customs Enforcement and other federal agencies to maintain office space at the Rikers Island jail complex. City lawmakers filed a lawsuit in April accusing Adams of entering into a “corrupt quid pro quo bargain” with the Trump administration in exchange for the U.S. Justice Department dropping criminal charges against him.

Rosado temporarily blocked the executive order in April. In granting a preliminary injunction, she said city council members have “shown a likelihood of success in demonstrating, at minimum, the appearance of a quid pro quo whereby Mayor Adams publicly agreed to bring Immigration and Customs Enforcement (”ICE”) back to Rikers Island in exchange for dismissal of his criminal charges.”

Rosado cited a number of factors, including U.S. border czar Tom Homan’s televised comments in February that if Adams did not come through, “I’ll be in his office, up his butt saying, ‘Where the hell is the agreement we came to?’ ”

Adams has repeatedly denied making a deal with the administration over the criminal case. He has said he deputized his first deputy mayor, Randy Mastro, to handle decision-making on the return of ICE to Rikers Island to make sure there was no appearance of any conflict of interest.

Rosado said that Mastro reports to Adams and “cannot be considered impartial and free from Mayor Adams’ conflicts.”

Mastro said in a prepared statement Friday the administration was confident they will prevail in the case. “Let’s be crystal clear: This executive order is about the criminal prosecution of violent transnational gangs committing crimes in our city. Our administration has never, and will never, do anything to jeopardize the safety of law-abiding immigrants, and this executive order ensures their safety as well,” Mastro said.

City Council Speaker Adrienne Adams, who is running in the Democratic primary for mayor, called the decision a victory for public safety.

“New Yorkers are counting on our city to protect their civil rights, and yet, Mayor Adams has attempted to betray this obligation by handing power over our city to Trump’s ICE because he is compromised,” she said in a prepared statement.

Getty Images is facing off against artificial intelligence company Stability AI in a London courtroom for the first major copyright trial of the generative AI industry.

Opening arguments before a judge at the British High Court began on Monday. The trial could last for three weeks.

Stability, based in London, owns a widely used AI image-making tool that sparked enthusiasm for the instant creation of AI artwork and photorealistic images upon its release in August 2022. OpenAI introduced its surprise hit chatbot ChatGPT three months later.

Seattle-based Getty has argued that the development of the AI image maker, called Stable Diffusion, involved “brazen infringement” of Getty’s photography collection “on a staggering scale.”

Tech companies have long argued that “fair use” or “fair dealing” legal doctrines in the United States and United Kingdom allow them to train their AI systems on large troves of writings or images. Getty was among the first to challenge those practices when it filed copyright infringement lawsuits in the United States and the United Kingdom in early 2023.

“What Stability did was inappropriate,” Getty CEO Craig Peters told The Associated Press in 2023. He said creators of intellectual property should be asked for permission before their works are fed into AI systems rather than having to participate in an “opt-out regime.”

Getty’s legal team told the court Monday that its position is that the case isn’t a battle between the creative and technology industries and that the two can still work together in “synergistic harmony” because licensing creative works is critical to AI’s success.

“The problem is when AI companies such as Stability AI want to use those works without payment,” Getty’s trial lawyer, Lindsay Lane, said.

She said the case was about “straightforward enforcement of intellectual property rights,” including copyright, trademark and database rights.

Getty Images “recognizes that the AI industry is a force for good but that doesn’t justify those developing AI models to ride roughshod over intellectual property rights,” Lane said.

Stability AI had a “voracious appetite” for images to train its AI model, but the company was “completely indifferent to the nature of those works,” Lane said.

Stability didn’t care if images were protected by copyright, had watermarks, were not safe for work or were pornographic and just wanted to get its model to the market as soon as possible, Lane said.

“This trial is the day of reckoning for that approach,” she said.

Stability has argued that the case doesn’t belong in the United Kingdom because the training of the AI model technically happened elsewhere, on computers run by U.S. tech giant Amazon.

The judge’s decision is unlikely to give the AI industry what it most wants, which is expanded copyright exemptions for AI training, said Ben Milloy, a senior associate at UK law firm Fladgate, which is not involved in the case.

But it could “strengthen the hand of either party – rights holders or AI developers – in the context of the commercial negotiations for content licensing deals that are currently playing out worldwide,” Milloy said.
In the years after introducing its open-source technology, Stability confronted challenges in capitalizing on the popularity of the tool, battling lawsuits, misuse and other business problems.

Stable Diffusion’s roots trace back to Germany, where computer scientists at Ludwig Maximilian University of Munich worked with the New York-based tech company Runway to develop the original algorithms. The university researchers credited Stability AI for providing the servers that trained the models, which require large amounts of computing power.

Stability later blamed Runway for releasing an early version of Stable Diffusion that was used to produce abusive sexual images, but also said it would have exclusive control of more recent versions of the AI model.

Stability last year announced what it described as a “significant” infusion of money from new investors including Facebook’s former president Sean Parker, who is now chair of Stability’s board. Parker also has experience in intellectual property disputes as the co-founder of online music company Napster, which temporarily shuttered in the early 2000s after the record industry and popular rock band Metallica sued over copyright violations.
