A Texas court scrapped a $26 million verdict against the drugmaker stemming from the first trial. The court found no evidence that Robert Ernst suffered a fatal heart problem from a blood clot triggered by Vioxx. He had been taking the now-withdrawn drug for eight months before being stricken in May 2001.

A New Jersey appeals court separately voided $9 million of the nearly $14 million awarded to John McDarby in 2006 by a jury in Atlantic City. The panel found that New Jersey's Product Liability Act was pre-empted by the federal Food Drug and Cosmetic Act.

Dustin Turner is hoping to overturn his conviction based on a confession by a fellow trainee who also went to prison for the crime. A hearing was to resume Thursday morning in Virginia Beach Circuit Court.

On Wednesday, Billy Joe Brown testified that he alone killed Jennifer Evans in 1995. He said he became a Christian in prison and realized he had to come clean.

Brown also gave a sworn statement taking full responsibility for the killing in 2003.

After a judge determines whether Brown's confession is credible, the state appeals court must decide whether it would have changed the outcome of Turner's trial.

This expansion of employee rights stands in sharp contrast to a series of pro-business rulings limiting the rights of workers that were made last year by the Supreme Court.

Tuesday's decisions do not amount to a sharp change in the law. Most civil rights laws already protect employees against being punished for complaining of bias based on their race, religion, gender, national origin or age.

However, in both cases the court read an older law broadly to give employees more rights to sue for discrimination.

That closely watched ruling, which made it easier for inmates to get new hearings on DNA evidence that emerges after their trials, and the fallout from it have left House in limbo while a prosecutor methodically battles every effort from the courts to have him retried.

Federal judges have done as the high court ordered: They reviewed his murder case and concluded new evidence raises reasonable doubt about his guilt. Not allowed to overturn the conviction, they took the extraordinary step of giving Tennessee a six-month deadline to bring House to trial or release him.

And still House, 46, is locked up in a Nashville prison.

An appeals court ruled in his favor this month, but that ruling also reset the 180-day countdown at zero.

U.S. District Judge Harry S. Mattice Jr. has scheduled a hearing for Wednesday to consider terms and conditions of House's release, but prosecutors are taking their time in setting a date for a new trial.

"The Supreme Court has said, 'You just got the wrong person.' You would think ... that there would be some respect for that situation," said U.S. Circuit Judge Gilbert S. Merritt, who has heard portions of House's case and believes he isn't guilty of murder.

District Attorney Paul Phillips said he plans to retry House with old evidence from the first trial and some new evidence he wouldn't describe. He promises he has "proof beyond a reasonable doubt that Mr. House is guilty or we would not be re-prosecuting him."

For House's mother, it's hard not to think the state is delaying on purpose.

"What I really think, and I'm not the only one, is they just want him to linger in there until he dies. Then it will all go away, they think," Joyce House said recently at her white ranch-style home in Crossville, a town of about 10,000 some 100 miles east of Nashville.

Phillips denied prosecutors are intentionally putting off the case and noted the inmate's doctor testified House could live for decades with his illness.

"They just don't want to admit they made a mistake," Joyce House said. "They're not the only state that's ever made a mistake."

A report examines 123 terrorist cases from the past 15 years, and the study's two principal authors say that the courts were able to produce just, reliable results while protecting national security.

The report comes at a time when the Bush administration's system of military commissions remains mired in delays.

Whether the case is the first attack on the World Trade Center in 1993 or the East African embassy bombings in 1998, judges, juries, defense attorneys and prosecutors are able to get the job done correctly, they say.

Although the justice system is far from perfect, it has proved to be adaptable and has successfully handled a large number of important and challenging terrorism prosecutions, said New York lawyers Richard Zabel and James Benjamin of the law firm Akin Gump Strauss Hauer & Feld.

In two employment cases, one involving race and the other, age, the court took an expansive view of workers' rights and avoided the narrow, ideology-based decisions that marked its previous term.

The justices read parts of an 1860s civil rights act and the main anti-age bias law to include the right to sue over reprisals even though neither provision expressly prohibits retaliation.

Justice Stephen Breyer, writing for the court in a case involving a black employee at a Cracker Barrel restaurant who was fired, said that previous Supreme Court decisions and congressional action make clear that retaliation is covered.

The idea that a provision of the Civil Rights Act of 1866, known as section 1981, "encompasses retaliation claims is indeed well-embedded in the law," Breyer said in the 7-2 ruling.
