A federal appeals court panel refused to order the reinsertion of Terri Schiavo's feeding tube, hours after the severely brain-damaged woman's father said she was weakening and down "to her last hours."

In its ruling Friday, a three-judge panel of the 11th Circuit Court of Appeals (search) in Atlanta said it had already ruled on most of the issues raised in the latest appeal, and that other issues raised did not apply to the case.

It marked the third time in four days the court had denied an emergency request made by Schiavo's parents, Bob and Mary Schindler. Attorneys for the parents said they planned to appeal, but would wait until Saturday morning.

Doctors have said Schiavo would probably die within a week or two of the feeding tube being removed, which was done March 18 after a judge sided with her husband's argument that she would not want to be kept alive artificially.

As she entered her second week without the tube that sustained her life for 15 years, dehydration took its toll on the 41-year-old woman. Her tongue and eyes were bleeding and her skin was flaking off, said Barbara Weller (search), the Schindlers' attorney.

"Terri is weakening. She's down to her last hours. Something has to be done and has to be done quick," said Bob Schindler, who visited his daughter Friday morning. After a later visit, he added: "I told her that we're still fighting for her, and she shouldn't give up because we're not. But I think the people who are anxious to see her die are getting their wish."

The 11th U.S. Circuit Court of Appeals was the same court that has ruled against the parents twice this week.

Attorneys for Michael Schiavo (search), Terri's husband, argued that the Schindlers had abandoned all pretense of the law and are simply making "a pure emotional appeal."

Terri Schiavo suffered brain damage in 1990 when her heart stopped briefly from a chemical imbalance believed to have been brought on by an eating disorder. She left no living will.

Another legal maneuver Friday included a late afternoon filing asking Pinellas Circuit Judge George Greer (search) to order the reinsertion of the tube, claiming Terri Schiavo tried to say "I want to live" when her tube was removed. The motion said Schiavo was asked to repeat that phrase and responded: "AHHHHH" and "WAAAAAAA."

Doctors who have examined her for the court case have said her previous utterances weren't speech, but were involuntary moans consistent with someone in a vegetative state. Greer, who had ordered the tube removed, was expected to announce a decision by noon Saturday. Greer also denied a new request by the parents to remove himself from the case.

In a hearing, Schindler attorney David Gibbs III urged Greer to act quickly because he expected "Terri to step into eternity this Easter weekend." George Felos, the attorney for Michael Schiavo, said the belief Terri Schiavo can speak was "crossing the line" into an abuse of the legal system.

Earlier in the day, U.S. District Judge James Whittemore wrote that the parents could not establish "a substantial likelihood of success on the merits" of their case. He also noted "the difficulties and heartbreak the parties have endured throughout this lengthy process."

After Friday's appellate court ruling, Schiavo's parents again pleaded with Gov. Jeb Bush to intervene by taking temporary custody of their daughter while court challenges are argued.

"With the stroke of his pen, he could stop this," Bob Schindler said. "He's put Terri through a week of hell and my family though a week of hell. I implore him to put a stop to this. He has to stop it. This is judicial homicide."

Bush said Thursday he is not willing to go beyond the boundaries of his powers. He has been a staunch supporter of the Schindlers, and his office was still clinging to hope Friday that the courts would allow the state to provide emergency care for Schiavo.

"We are continuing to do whatever we can, and we are pursuing all the options available to us in this case," Bush spokesman Jacob DiPietre said.

Michael Schiavo's attorney also rejected arguments that Bush could overturn years of court orders in the husband's favor.

"Jeb Bush does not own the state of Florida and just cannot impose his will on Terri Schiavo," Felos told CBS' "The Early Show" on Friday. He declined to comment to The Associated Press.

But supporters of Michael Schiavo said the time for challenges had ended.

"All the politicians who injected themselves into this tragic and personal matter now need to begin respecting both the law and the legal process even if they disagree with the result that was reached in this case," said Howard Simon, executive director of the American Civil Liberties Union's Florida chapter.

Terri Schiavo has been without food and water longer than she was in 2003, when the tube was removed for six days and five hours. It was reinserted when Bush and the Legislature pushed through a law that was later thrown out by the state Supreme Court.

Outside the hospice, eight more people — including a 10-year old boy and 13-year-old twin girls — were arrested Friday for trying to bring her water.

"I don't want her to die," Joshua Heldreth, 10, from North Carolina, said before his arrest. "I'm not afraid because God is with me."

On Thursday, a Rockford, Illinois, man was arrested in Seminole after trying to steal a weapon from a gun shop. Michael W. Mitchell, 20, told deputies he wanted to "take some action and rescue Terri Schiavo" after he visited the Pinellas Park hospice where she lives, an official said. Seminole is about 5 miles west of Pinellas Park.

Also, the FBI said a man was arrested Friday in Fairview, North Carolina, on charges of sending an e-mail threat, allegedly for offering a $250,000 bounty for Michael Schiavo's death and $50,000 for that of a judge in the case. The FBI did not immediately identify the judge.
