A federal appeals court panel in Atlanta has refused to order Florida doctors to reconnect the feeding tube that had been keeping Terri Schiavo alive.
Her parents vow to take their fight to the U.S. Supreme Court.
An appeal is still pending in the Eleventh Circuit Court of Appeals on whether Schiavo's right to due process was violated.
Gov. Jeb Bush says he will call on the Florida Legislature to spare Terri's life.
The Legislature had stepped in before and had her feeding tube reinserted in 2003 after six days at that time. But the state Supreme Court struck down "Terri's Law" as unconstitutional.
Florida lawmakers may consider another bill today and state Senator Daniel Webster says it would be the measure's last chance.
A spokesman for Speaker Allan Bense says the state House could take up the bill very quickly if the Senate sends it.
