Judge Sharon Keller is the presiding judge of the Texas Court of Criminal Appeals. She is on trial nearly two years after refusing to keep the court open in September 2007 with Michael Wayne Richard's (ruh-SHARD's) execution imminent and his lawyers scrambling to file an appeal.

Keller faces five counts of judicial misconduct. She sat quietly at the defense table as her special hearing got under way Monday. But she did stand to acknowledge that she planned to testify.

She could take the stand as early as Tuesday.

Oral arguments will be made in St. Paul before a three-judge panel of the Eighth Circuit Court of Appeals. The NFL hopes for a quick ruling that would let it suspend the players for four games at the start of the season.

The players took the weight-loss supplement StarCaps, which contained an unlisted but banned diuretic that can mask the presence of steroids.

Their legal fight remains alive in a Minnesota state court. But the NFL is asking the federal appeals court to rule that the players' union contract and federal law trump state law in this case.

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.

"We close at 5," Judge Sharon Keller told a court staffer Sept. 25, 2007.

The appeal was never heard, and four hours later, convicted killer Michael Wayne Richard was executed. Now it's Keller who will be before a judge, facing charges that could end her career in a special trial that begins Monday in San Antonio. Denying the rights of a condemned man is among five judicial misconduct charges that Keller, the presiding judge of the Texas Court of Criminal Appeals, is up against.

Nicknamed "Sharon Killer" among critics for a tough-on-crime reputation crafted over the years, Keller is the highest-ranking judge in Texas to be put on trial by the state Commission on Judicial Conduct. The judge overseeing the trial will submit a report to the commission, which could dismiss the charges, issue a censure or suggest Keller be removed from the bench.

Keller, a Republican who has served on the court since 1994, has not spoken publicly since being charged in February. Her attorney, Chip Babcock, said the widely repeated narrative of what happened the day Richard was executed isn't accurate.

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.
