The updated Chron story on the overturning of Andrea Yates' convictions has some info on what might come next.
The decision means that if prosecutors cannot get Yates' capital murder conviction restored through appeals, they will have to decide whether to put Yates on trial again.
"We are going to ask for a rehearing," Assistant District Attorney Alan Curry said.
Prosecutors said Thursday that they will ask the 1st Court of Appeals to reconsider its ruling. If that is unsuccessful, they expect to take the case to the Texas Court of Criminal Appeals, the state's highest court.
Prosecutors argued that Dietz's remarks about the TV program were peripheral, compared with other evidence suggesting Yates was guilty and sane at the time of the killings.
If the appeals court's ruling is upheld, the District Attorney's Office will have to decide whether to seek a new trial.
Texas law allows for a new trial if a witness gives false testimony that may have influenced the verdict, legal experts said.
The decision surprised juror Leona Baker, who said Thursday she and the other jurors discounted Dietz's testimony, saying it did not have any weight in their decision to convict Yates.
"We heard (Dietz) talk about the episode of Law & Order, but it was never made clear that she actually watched that particular episode," Baker said.
Dru Stevenson, a criminal law professor at the South Texas College of Law, said the ruling didn't surprise him, adding that the testimony was "prejudicial."
Yates' attorneys said they would represent her again if a new trial is ordered, but Stevenson said that is unlikely.
"If I was a betting man, I would bet they will reach some sort of plea bargain," he said.
Yates' husband, Rusty, who filed for divorce in July, said on CNN's Larry King Live Thursday that he believes prosecutors should not pursue the case.
"I would like to see them drop the charges against her, and I would like to see her go to a state mental hospital until she is stable," he said. "I say safe, stable medically. I'd say it would be a few years.
Yates' mother, Jutta Karin Kennedy reacts to the decision:
"I have mixed emotions," said Kennedy, exhausted after spending the day talking to reporters and answering calls from friends and well-wishers. "If this does any good, I'll be happy. I just don't know."
Kennedy alternated between feelings of vindication — she has said all along that Andrea was not murderous, but mentally ill — and fear of a new trial with the same outcome.
She sighed heavily, not sure if she or her 40-year-old daughter could face that ordeal.
Since Yates has been at Skyview, near Rusk in northeast Texas, her mom has visited several times a month.
"It's a good day when I can go visit," Kennedy said. The other days are harder.
Kennedy said she got the news of the conviction reversal when the anchors for NBC's Today show, Katie Couric and Matt Lauer, called about 7 a.m.
"I was speechless, shaking," she said. "The decision came out of the blue. I wasn't expecting to hear anything for four to six months."
She believes her daughter got the news an hour or two later from a Skyview warden. For now, she can only guess Yates' reaction. "I think she's been hoping for a reduction in her sentence. I just don't know."
"In a case like this, you ought to be very, very sure that the testimony you are giving is accurate," said Lucy Puryear, a forensic psychiatrist at Baylor College of Medicine who testified in Yates' defense. "I was incredulous that in a case where someone's life depended on it, that he could give testimony that was wrong, and so egregiously wrong it could have had an influence on the decision of the jury."
Dietz did not return phone calls for comment. In a prepared statement issued Thursday, he said he made an honest mistake in part because he had not anticipated answering questions about Law & Order.
"My spontaneous recall about particular shows is admittedly imperfect," Dietz said.
One of Puryear's Baylor colleagues, psychiatry professor Victor Scarano, said Dietz's gaffe is hard to understand given his reputation for thoroughness.
"He is usually very careful about what he does," Scarano said. "When we do our work, we usually are very scrupulous that what we have are the facts. We understand that we are going to be vulnerable to cross-examination, so we have to have our ducks in a row. How this happened, I don't know. Unfortunately, it will hurt him."
After the Yates case, Dietz was retained by Tyler prosecutors pursuing a capital murder conviction for Deanna Laney, charged with bludgeoning two of her children to death in 2003. Dietz surprised prosecutors by concluding that Laney, who said she was acting under orders from God, was "a textbook case" of insanity. Laney was found not guilty.
That shows he's not just a gun for hire, supporters say.
"Dietz is to my knowledge just as honest and ethical as he can be," said William Reid, a Texas forensic psychiatrist who, like Dietz, has served as president of the American Academy of Psychiatry and the Law. "He has felt extremely badly about his error. I've talked to him personally about it and heard him speak to others."
Reid said he did not think the mistake ultimately will affect Dietz's credibility or his popularity as a witness.
"It was an accident on his part," Reid said. "He did give an off-the-cuff answer that there had been this episode. The person who took it to the next level and said (Yates) had seen it was the prosecutor."
