The federal law that President Bush signed early yesterday in an effort to prolong Terri Schiavo's life appears to contradict a right-to-die law that he signed as Texas governor

In 1999, then-Gov. Bush signed the Advance Directives Act, which lets a patient's surrogate make life-ending decisions on his or her behalf. The measure also allows Texas hospitals to disconnect patients from life-sustaining systems if a physician, in consultation with a hospital bioethics committee, concludes that the patient's condition is hopeless.

While Congress and the White House were considering legislation recently in the Schiavo case, the Texas law faced its first high-profile test. With the permission of a judge, a Houston hospital cut off life support for a badly deformed 6-month-old baby last week against his mother's wishes after doctors determined that continuing life support would be futile. The baby died almost immediately.

"The mother down in Texas must be reading the Schiavo case and scratching her head," said Dr. Howard Brody, the director of Michigan State University's Center for Ethics and Humanities in the Life Sciences. "This does appear to be a contradiction."
