The 9th U.S. Circuit Court of Appeals said the law amounted to unconstitutional meddling in U.S. foreign policy.

It based its 2-1 ruling on a 2003 U.S. Supreme Court decision that struck down another California law designed to help Holocaust survivors collect on Nazi-era insurance policies.

The federal government does not recognize the mass killings of Armenians during World War I as genocide, but the California Legislature did in 2000 when it enacted the disputed law.

About half of the people of Armenian descent living in this country reside in California.

Lawyer Brian Kabateck, who represents Armenian-American heirs, plans to appeal.

"The ruling is wrong. It's a disaster," Kabateck said. "The one million Armenians that live in California today have been told by the court that even the use of the word 'genocide' by a government is illegal."

Judge Sharon Keller is telling her side of the story for the first time nearly two years after Michael Wayne Richard was executed.

She'll continue testifying Wednesday. She was first called Tuesday to answer questions about refusing to keep the Texas Court of Criminal Appeals open past 5 p.m. when Richard's lawyers asked for more time to file their rushed appeal on Sept. 25, 2007.

Keller says the move wasn't a ruling on the merits of the request.

She says she received a call shortly before court closed about an appeal running late and that she knew it concerned the execution but that no explanation was given.

The court told a federal judge to hold a hearing to decide whether evidence "that could not have been obtained at the time of trial" could establish Davis' innocence. His case has become a rallying cry for death penalty opponents.

Davis' attorneys contend he deserves a new trial because new evidence proves he was mistakenly identified as the killer. They say several trial witnesses have recanted their testimony, and others who did not testify during the trial have said another man confessed to the killing.

"This is exactly what we asked for," said Jason Ewart, Davis' attorney. "It's been years since these witnesses have come forward, and they've never had their day in court. And now they will."

Davis was convicted 18 years ago for the 1989 slaying of Savannah, Ga., police officer Mark MacPhail, who was shot twice while working off-duty as a security guard at a bus station. He was gunned down after rushing to the aid of a homeless man who had been attacked.

Davis' execution has been delayed three times, including a ruling by an appeals court last year that gave the 40-year-old another chance to press his appeal. The panel rejected the appeal in April, and federal and state courts have repeatedly denied his request for a new trial.

Davis has spent 18 years on death row for the 1989 slaying of Savannah, Ga., police officer Mark MacPhail. Davis' attorneys insist that he is innocent and deserves a new trial because several witnesses at his trial have recanted their testimony.

The high court ordered a federal judge in Georgia to determine whether there is evidence "that could not have been obtained at the time of trial (that) clearly establishes petitioner's innocence."

Defense lawyers had appealed to the Supreme Court after a federal court denied a new trial request in April.

"The substantial risk of putting an innocent man to death clearly provides an adequate justification for holding an evidentiary hearing," said Justice John Paul Stevens, writing for the court. Justices Ruth Bader Ginsburg and Stephen Breyer concurred with Stevens.

MacPhail was slain 20 years ago while working off-duty as a security guard at a bus station. He had rushed to help a homeless man who had been pistol-whipped at a nearby parking lot, and was shot twice when he approached Davis and two other men. Witnesses identified Davis as the shooter at his 1991 trial.

Marshall had faced two counts of simple battery stemming from a March 4, 2008, argument with then-girlfriend Rasheedah Watley at the Atlanta condominium the couple shared.

Marshall said after the verdict in Fulton County State Court that he had some butterflies in his stomach when deliberations began, but was confident in the work of his lawyers.

"I'm just happy now that legally and emotionally we can move past this," he said, adding that he appreciated the support of teammates and fans. He said he planned to celebrate Friday night by watching his teammates in an offseason game against the San Francisco 49ers.

His lawyer Harvey Steinberg expressed gratitude to NFL commissioner Roger Goodell for waiting for the verdict before deciding whether to take any league action. Marshall was suspended for last year's season opener after a series of domestic disputes, and Goodell had said a conviction in the Atlanta case could have led to a second suspension.

Before the verdict was announced, the judge cautioned that no outbursts would be tolerated and asked anyone who might not be able to comply to leave the courtroom. Watley, who was sitting with her family, got up and left. Her family was visibly disappointed at the verdict but declined comment.

Authorities say the 38-year-old Steele led San Mateo County sheriff's deputies on a car chase on July 11 that ended with him streaking into a home and then into woods near Redwood City.

Deputies say it took a Taser and two shots from a bean bag gun to bring him down.
