A federal appeals court in Philadelphia has ruled that an anti-abortion protester arrested near the Liberty Bell in 2007 can't collect damages from park rangers who detained him.

The three-judge panel on Thursday upheld a lower-court ruling to dismiss 32-year-old Michael Marcavage's lawsuit against two Independence National Historic Park rangers. The Philadelphia Daily News reported on the panel's decision.

The suit stemmed from Marcavage's arrest after he refused to move his protest to another area of the park. A federal magistrate convicted the Lansdowne resident of two misdemeanors.

Marcavage appealed and claimed rangers violated his constitutional rights. In 2010, a federal appeals court threw out the misdemeanor convictions. Then Marcavage filed an amended complaint arguing that park rangers were liable for unspecified damages. The court ruled against him.

A federal appeals court refused Thursday to unseal video recordings of a landmark trial on the constitutionality of California's same-sex marriage ban.

Siding with the ban's supporters, the 9th U.S. Circuit Court of Appeals in San Francisco ruled the public doesn't have the right to see the footage.

The 2010 trial lasted 13 days and was the first in a federal court to examine if prohibiting gay couples from marrying violates their constitutional rights.

It was open to the public and received widespread media coverage, so the recordings would not have revealed any new evidence or testimony.

In deciding to keep the videos under seal, a three-judge 9th Circuit panel cited a promise by the trial judge that the footage would not be seen outside his courtroom.

Former U.S. District Judge Vaughn Walker had staff members make the recordings with the caveat that the footage would be used only by him to help him reach a verdict.

Walker, who has since retired and revealed he is in a long-term relationship with another man, originally wanted to broadcast the trial in other federal courthouses and on YouTube.

The U.S. Supreme Court forbade him from moving forward with that plan after the ban's sponsors argued that distributing trial footage could subject their witnesses to harassment. At the time, the 9th Circuit did not allow the federal courts within its jurisdiction to televise trials. The appeals court since has adopted rules that would permit trials to be broadcast under limited conditions.

The children at Miramonte Elementary School never complained about their third-grade teacher. Not, authorities said, when he blindfolded them, not when he put tape over their mouths or even placed live cockroaches on their faces.

He told them it was a game and then photographed them, creating images that would eventually lead to his arrest, investigators said of Mark Berndt, who is scheduled to be arraigned Wednesday on charges that he committed lewd acts on 23 boys and girls, ages 6 to 10, between 2008 and 2010. He has hired a lawyer and has made no statements to authorities, said Los Angeles County sheriff's spokesman Steve Whitmore.

The investigation began when a film processor found Berndt's photos more than a year ago. Since the discovery, the school district fired Berndt and police put him under surveillance.

"If it wasn't for the film processor, this could still be continuing today," said sheriff's Lt. Carlos Marquez.

Berndt was arrested Monday at his home in Torrance and was being held on $2.3 million bail.

Some parents picking up their pre-kindergarteners at the school on Tuesday complained that officials at the school in South Los Angeles should have notified them when the photos were found.

A federal appeals court panel has upheld the conviction and sentence of a University of Tennessee student in the hacking of Sarah Palin's email in 2008.

The three judge panel in a Monday decision affirmed the conviction of 24-year-old David Kernell. A Knoxville jury last April convicted Kernell of unauthorized access to a protected computer and destroying records to impede a federal investigation.

Kernell's attorney, Wade Davies, contended at trial that Kernell had no criminal intent and that guessing his way into the email account was a prank. Palin was governor of Alaska and John McCain's GOP running mate at the time.

Kernell was released in November after serving less than 11 months.

Davies said he will seek a review by the full U.S. 6th Circuit Court of Appeals.

A judge overstepped his authority when he tried to ban enforcement around the world of an $18 billion judgment against Chevron Inc. for environmental damage in Ecuador, a federal appeals court said Thursday.

The three-judge panel of the 2nd U.S. Circuit Court of Appeals explained why it lifted the ban last year and blocked a judge from staging a trial to decide if the judgment was obtained fairly.

It said the judge has authority to block collection if Ecuadorean plaintiffs move against Chevron in New York, but law does not give him authority "to dictate to the entire world which judgments are entitled to respect and which countries' courts are to be treated as international pariahs."

The judgment came last February after nearly two decades of litigation that stemmed from the poisoning of land in the Ecuadorean rainforest while the oil company Texaco was operating an oil consortium from 1972 to 1990 in the Amazon. Texaco became a wholly owned subsidiary of Chevron in 2001.

Chevron obtained an order from U.S. District Judge Lewis A. Kaplan in March blocking Ecuadorean plaintiffs from trying to collect the $18 billion until he could stage a trial to determine whether the judgment was fraudulently obtained.

The Ecuadorean plaintiffs appealed Kaplan's ruling to the 2nd Circuit. The appeals court heard oral arguments and then issued an order in September lifting Kaplan's block on collection efforts. On Thursday, it went a step further, tossing out the portion of Chevron's challenge to the judgment that sought to block its enforcement anywhere in the world.

The Supreme Court on Monday blocked a California law that would require euthanizing downed livestock at federally inspected slaughterhouses to keep the meat out of the nation's food system.

The high court ruled that the state's 2009 state law was blocked from going into effect by federal law administered by the Agriculture Department's Food Safety and Inspection Service. .

Federal law "precludes California's effort ... to impose new rules, beyond any the FSIS has chosen to adopt, on what a slaughterhouse must do with a pig that becomes non-ambulatory during the production process," said Justice Elena Kagan, who wrote the court's unanimous opinion.

California strengthened regulations against slaughtering so-called "downer" animals after the 2008 release of an undercover Humane Society video showing workers abusing cows at a Southern California slaughterhouse. Under California law, the ban on buying, selling and slaughter of "downer" cattle also extends to pigs, sheep and goats.

But pork producers sued to stop the law, saying the new law interfered with federal laws that require inspections of downed livestock before determining whether they can be used for meat.
