The Terri Schiavo Case: Legal, Ethical, and Medical Perspectives
Joshua E. Perry, JD, MTS; Larry R. Churchill, PhD; and Howard S. Kirshner, MD
Although tragic, the plight of Terri Schiavo provides a valuable
case study. The conflicts and misunderstandings surrounding her
situation offer important lessons in medicine, law, and ethics.
Despite media saturation and intense public interest, widespread
confusion lingers regarding the diagnosis of persistent vegetative
state, the judicial processes involved, and the appropriateness of
the ethical framework used by those entrusted with Terri Schiavo’s
care. First, the authors review the current medical understanding
of persistent vegetative state, including the requirements for pa-
tient examination, the differential diagnosis, and the practice
guidelines of the American Academy of Neurology regarding ar-
tificial nutrition and hydration for patients with this diagnosis.
Second, they examine the legal history, including the 2000 trial,
the 2002 evidentiary hearing, and the subsequent appeals. The
authors argue that the law did not fail Terri Schiavo, but produced
the highest-quality evidence and provided the most judicial review
of any end-of-life guardianship case in U.S. history. Third, they
review alternative ethical frameworks for understanding the Terri
Schiavo case and contend that the principle of respect for auton-
omy is paramount in this case and in similar cases. Far from being
unusual, the manner in which Terri Schiavo’s case was reviewed
and the basis for the decision reflect a broad medical, legal, and
ethical consensus. Greater clarity regarding the persistent vegeta-
tive state, less apprehension of the presumed mysteries of legal
proceedings, and greater appreciation of the ethical principles at
work are the chief benefits obtained from studying this provoca-

enced severe hypoxia for several minutes. She had not ex-
ecuted a living will or a durable power of attorney. Four
months after her injury, Mrs. Schiavo was judged incom-
petent and her husband, Michael Schiavo, was appointed
her legal guardian without objection from her parents,
Robert and Mary Schindler. Because she was unable to
swallow, Mrs. Schiavo underwent placement of a percuta-
neous endoscopic gastrostomy (PEG) tube. By late 1990,
Mrs. Schiavo was determined to be in a persistent vegeta-

UNDERSTANDING THE PERSISTENT VEGETATIVE STATE
The Schiavo case rests critically on the concept of the
persistent vegetative state and the certainty of the predic-
tion that a patient in this state will have no meaningful
recovery. The persistent vegetative state is distinguished
from several other states of reduced consciousness. Brain
death implies the loss of not only all higher brain functions
but also all brainstem functions, including pupillary light
reflexes, reflex eye movements, respirations, and gag and
corneal reflexes. Determination of brain death is straight-
forward and is generally accepted as a criterion for death.
Coma is a complete state of unresponsiveness to stimuli,
although the patient may have brainstem reflexes. Stupor
and obtundation refer to states of reduced consciousness in
which meaningful responses are still possible, if the patient
receives enough stimulation. Finally, the “locked-in syn-
drome” denotes the condition of a patient who is paralyzed
and cannot move or speak but is completely awake. Such
patients can often communicate by blinking their eyes or
looking up and down.
The American Academy of Neurology, along with rep-
resentatives of the American Neurological Association, the
Child Neurology Society, the American Association of
Neurological Surgeons, and the American Academy of Pe-
diatrics, set up a Multi-Society Task Force to establish cri-
teria for diagnosing the persistent vegetative state. In 1994,
the Task Force published its findings (1–3), which have
been adopted as a practice guideline by the American
Academy of Neurology. The Task Force estimated that
10 000 to 25 000 adults and 6000 to 10 000 children in
the United States are in the persistent vegetative state. The
criteria for this diagnosis must be met at least 1 year after
traumatic brain injury in young patients and at least 3
months after nontraumatic illnesses.
The Task Force reviewed case series from the litera-
ture, which included 434 adults and 106 children with
traumatic brain injury and 169 adults and 45 children with
nontraumatic injuries, mostly related to hypoxia. Of the
patients in the persistent vegetative state for more than 3
months after nontraumatic injuries, the probability of
moderate disability or good recovery was 1% (99% CI, 0%
to 4%), but for patients still in the persistent vegetative
state at 6 months, this probability was 0%. No patient,
even those with traumatic brain injury, has been reported
to recover after a full year of being in the persistent vege-
tative state. Delayed recoveries after traumatic brain injury
are more common than with nontraumatic brain injuries.
Certainly, no patient has recovered after 15 years, the pe-
riod during which Terri Schiavo survived in this state. The
criteria make clear that the patient can have periods of
sleep alternating with periods of an awake-like state, in

which his or her eyes are open and may move about, and
the patient may breathe, yawn, and open his or her mouth,
but not interact meaningfully with others (Table 1).
The Task Force discussed several causes of the persis-
tent vegetative state. After acute traumatic and nontrau-
matic brain injury, this state usually evolves out of an ini-
tial coma. In degenerative and metabolic disorders of the
nervous system, the patient gradually sinks into this state.
Severe developmental malformations of the central nervous
system can produce the persistent vegetative state, but only
in patients with anencephaly can this diagnosis be made
before 3 months of observation. In all cases, the persistent
vegetative state is a diagnosis based on observation over
time. Diagnostic tests, such as computed tomography (CT)
scanning or magnetic resonance imaging (MRI), can doc-
ument the loss of much of the cerebral cortex (4, 5). Func-
tional brain imaging methods, such as functional MRI,
single-photon emission CT, and positron emission tomog-
raphy scanning (6, 7), may show the cortex’s lack of
arousal to stimuli, but these tests are still investigational
and have been validated only in small case series. In gen-
eral, the position of the Task Force was that diagnostic
tests “may support the dx of PVS [persistent vegetative
state], but none adds to the diagnostic specificity with cer-
tainty” (3). This recommendation has not changed in the
years since the publication of the Task Force guidelines. A
related issue is the distinction between persistent and per-
manent vegetative states. In general, although a vegetative
state can be diagnosed at 1 month after an acute brain
injury or hypoxia, the permanent vegetative state can be
diagnosed after 3 months in patients with nontraumatic
brain injuries and after 12 months in patients with trau-
matic brain injuries. This renders the definition of perma-
nent vegetative state identical to the definition given above
for persistent vegetative state. The guidelines also state: “A
PVS [persistent vegetative state] patient becomes perma-
nently vegetative when the diagnosis of irreversibility can
be established with a high degree of clinical certainty, i.e.,
when the chance of regaining consciousness is exceedingly
rare” (3). A final provision of the American Academy of
Neurology practice guidelines discusses the decision to
withhold fluids and nutrition through a feeding tube (Ta-
ble 2) (8).
THE LEGAL HISTORY AND COMMENTARY
Throughout the early 1990s, Michael Schiavo and the
Schindlers worked together coordinating extensive rehabil-
itation efforts for Mrs. Schiavo, including regular and ag-
gressive physical, occupational, and speech therapies. De-
spite their best efforts and explorations of all potentially
viable treatments, her condition failed to improve.
By the mid-1990s, Mr. Schiavo’s relationship with the
Schindlers had chilled. Increasingly, Mr. Schiavo under-
stood that his wife’s condition was irreversible. In addition,
he insisted that he knew his wife would not want to live in
a persistent vegetative state. The Schindlers, however, in-
sisted that Mrs. Schiavo be kept alive through artificial
nutrition and hydration. Unable to reach a consensus with
his wife’s parents, Mr. Schiavo decided not to request with-
drawal of the PEG tube. Instead, he petitioned the guard-
ianship court “to function as the proxy” and asked the
court “to make an independent determination of Mrs.
Schiavo’s terminal condition and to make the decision to
continue or discontinue life-prolonging procedures” (9).
In January 2000, Judge George Greer held a trial to
resolve the dispute over the extent of Terri Schiavo’s neu-
rologic devastation and to determine how she would exer-
cise her right of privacy, or liberty interest, to forgo life-
supporting medical treatment, if she were able to
communicate. The proceeding was adversarial in nature,
with both Mr. Schiavo and the Schindlers presenting wit-
nesses and making arguments pursuant to the rules of ev-
idence and civil procedure.
It is important to note that end-of-life guardianship
controversies, such as those that emerged in this case, are
resolved on the basis of state law, which varies throughout
the United States. In Florida, both statutes and case law
recognize the fundamental right of every individual to con-
trol his or her person, regardless of the capacity to commu-
nicate (10). In Terri Schiavo’s case, where the inability to
communicate directly was established and no written med-
ical directive existed, Florida law considers previously made
oral declarations, as long as they satisfy the standard of
“clear and convincing evidence” (11).
At the 2000 trial, the opposing parties presented Judge
Greer with Mrs. Schiavo’s entire medical history, numer-
ous exhibits, and the testimony of 18 witnesses, including
the parties, 2 physicians, and various family members. On

gastrostomy tube, is a medical procedure”
“Treatments which provide no benefit to the patient or the family may be
discontinued. . . . Medical treatment provides no benefit to patients in a
persistent vegetative state, once the diagnosis is established”

the first issue of her medical condition and whether Mrs.
Schiavo had the ability or potential to communicate her
wishes directly, the court found that she met the statutory
definition of the persistent vegetative state and that there
was no hope of her regaining consciousness or the ability to
communicate (12). The court’s analysis then shifted to the
issue of exercising Mrs. Schiavo’s autonomy rights, inde-
pendently of state, family, or public opinion. After hearing
from all of the witnesses and observing their cross exami-
nations, Judge Greer determined that testimony from the 3
witnesses recalling Mrs. Schiavo’s prior oral declarations
that “she would not want to live like that” satisfied the
clear-and-convincing evidence standard (12). Accordingly,
the court ordered that the PEG tube be removed.
The Schindlers appealed Judge Greer’s decision. The
appellate court reviewed both the substantive evidence and
procedural formalities at the 2000 trial and concluded that
after 10 years in a persistent vegetative state with no hope
of recovery, the ultimate issue was whether Mrs. Schiavo
“would choose to continue the constant nursing care and
the supporting tubes . . . or whether she would wish to
permit a natural death process to take its course” (13). The
appellate court affirmed Judge Greer’s conclusion that the
clear and convincing evidence required removal of the
Judge Greer ordered cessation of Terri Schiavo’s arti-
ficial nutrition and hydration on 24 April 2001. Two days
later, however, the treatment resumed when the Schindlers
presented a different trial court judge with 7 affidavits
from licensed physicians. Although none of the physicians
had physically examined Mrs. Schiavo, each contended
that she was neither in a persistent vegetative state nor
beyond the aid of medical treatment. In 2002, after nu-
merous legal proceedings, the Schindlers successfully con-
vinced the appellate court “to permit discovery and con-
duct an evidentiary hearing only for the purpose of
assessing Mrs. Schiavo’s current medical condition, the na-
ture of the new medical treatments described in the affida-
vits and their acceptance in the relevant scientific commu-
nity . . .” (14).
At the 2002 hearing, again in the context of an adver-
sary proceeding, Judge Greer heard testimony from 5
board-certified experts whose examinations of Mrs. Schiavo
were videotaped. Mr. Schiavo’s 2 experts, as well as the
independent, court-appointed expert, were all neurologists
who unanimously concluded that Mrs. Schiavo had irre-
versible neurologic damage and was undoubtedly in a per-
sistent vegetative state. The Schindlers’ experts, 1 radiolo-
gist and 1 neurologist, questioned whether Mrs. Schiavo
was in such a state and advocated for the use of hyperbaric
oxygen and vasodilation therapies.
Judge Greer found the Schindlers’ experts unconvinc-
ing and their rehabilitation theories unsupported by the
mainstream neurologic community. “Viewing all of the ev-
idence as a whole, and acknowledging that medicine is not
a precise science,” the court found “the credible evidence
overwhelmingly support[ed] the view that Terri Schiavo
remain[ed] in a persistent vegetative state” (15). Accord-
ingly, the court once again ordered the withdrawal of the
feeding tube (15).
On appeal, Judge Greer’s decision was again scruti-
nized for both procedural and substantive error. The ap-
pellate court affirmed Judge Greer’s decision, emphasizing
that the proceedings in 2000 and again in 2002 had been
undertaken with care, objectivity, and according to “a cau-
tious legal standard designed to promote the value of life”
(16). In conclusion, the appellate court stated that the
“value of life” could be adequately promoted “if all people
are . . . entitled to a personalized decision about life-pro-
longing procedures” (16).
With Terri Schiavo’s “personalized decision” deter-
mined at the 2000 trial and her medical condition conclu-
sively confirmed at the 2002 hearing, artificial hydration
and nutrition were stopped for the second time, on 15
October 2003, pursuant to court order. This order was
superseded 6 days later when the Florida legislature passed
and Governor Jeb Bush signed Terri’s Law, which pro-
vided the governor unfettered discretion to order resump-
tion of Mrs. Schiavo’s medical treatment.
Eleven months later, the Florida Supreme Court held
Terri’s Law unconstitutional as a violation of separation of
powers (17), and a third date was set for removal of the
PEG tube. On 18 March 2005, the tube was removed for
the final time, and despite the intervention of Congress
and President George W. Bush, Terri Schiavo’s saga ended
with her death on 31 March 2005.
On 1 April 2005, an autopsy was performed, revealing
that Mrs. Schiavo’s brain was “grossly abnormal and
weighed only 615 grams”—less than half of the expected
weight for an adult her age—and showing neuronal loss in
her occipital lobes consistent with cortical blindness (18).
There was also extensive loss of neurons in the basal gan-
glia and in the hippocampus, and loss of Purkinje cells in
the cerebellum. In short, the findings from the autopsy
were fully consistent with the expectation of widespread,
hypoxic–ischemic brain damage. In addition, the presence
of an implanted thalamic stimulator explained why an
MRI scan was never done.
In our opinion, the law did not fail Terri Schiavo. In
fact, no end-of-life guardianship case in U.S. history has
generated as much high-quality evidence, judicial atten-
tion, or legal scrutiny as the Terri Schiavo case. Through-
out a lengthy trial and evidentiary hearing, countless mo-
tions, oral arguments, and numerous appeals to every
available state and federal court, this case shows that the
judicial process works at the end of life.
The Florida guardianship law was clear, and the law
was followed. The judiciary was charged with 2 questions:
1) What was Terri Schiavo’s medical condition? 2) In such
a condition, what would she choose to do? In the midst of
an intense and intractable family dispute, amid dizzying
media attention and unprecedented political intervention,
The Terri Schiavo Case
746 15 November 2005 Annals of Internal Medicine Volume 143 • Number 10
the judicial process produced 2 answers. The process and
the resulting answers were reviewed repeatedly by cautious,
nonpartisan judges who demonstrated restraint and care in
adjudicating Mrs. Schiavo’s case pursuant to her individual
liberty and privacy interests.
COMPETING ETHICAL FRAMEWORKS
Expressed as an ethical principle, the central focus in
this case is respect for autonomy (19). Many have argued,
however, that the proper moral framework is not auton-
omy at all, but rather sanctity of life, discrimination toward
the disabled community, or the moral character of those
empowered to decide. Examining these alternative frame-
works is important, both to discern why respect for auton-
omy is the key ethical feature of this case and to display the
weaknesses of the alternatives.
Several commentators argued that the central question
of the Terri Schiavo case is a struggle between sanctity of
life versus quality of life. For example, columnist David
Brooks advanced this thesis, neatly dividing the contending
parties into “social conservatives,” who believe in the “in-
trinsic value” of all life and “social liberals,” who emphasize
“quality” (20). However, this rendering of the ethical issues
is too neat, and it compounds descriptive vagueness with
stereotypes, thus ensuring that the debate remains at the
superficial level of moral slogans. Unless one adopts the
position that sheer biological existence is what is sacred
about human life, considerations of sanctity inevitably in-
volve judgments of quality. More important, this dichoto-
mous rendering of the issues begs the essential question of
whose notion of “sanctity” and “quality” counts. By taking
the autonomy and liberty interests of patients as the central
question, the courts preserved the prerogative of individu-
als to decide according to their own values, even after they
have lost the ability to speak for themselves.
Others felt passionately that discontinuing Terri
Schiavo’s artificial nutrition and hydration would initiate a
cascading disregard for disabled persons or others who are
judged to have poor quality of life (21). The fundamental
flaw with this approach is overgeneralization. It is descrip-
tively inaccurate to refer to a person in the persistent veg-
etative state as being disabled. For example, there are far
more differences than similarities between Terri Schiavo
and persons who have paralysis, such as the late Christo-
pher Reeve. A related kind of overgeneralization is the idea
that the action taken in the Terri Schiavo case has wide-
ranging public policy implications. The wisdom of decid-
ing this case within the moral framework of individual
autonomy and liberty interests is that it portends nothing
as a general policy for what should be done to and for other
persons in the persistent vegetative state. In fact, stressing
liberty as the fundamental issue means precisely that indi-
viduals will be able to choose for themselves and that a
variety of differing living wills and legitimate proxy deci-
sions can be honored.
Finally, some argued that Michael Schiavo should not
be allowed a voice in decisions concerning his wife’s treat-
ment because over the 15-year period of caring for her, he
developed a relationship with another woman. Those who
espoused this perspective seemed ignorant of Mr. Schiavo’s
aggressive attempts to rehabilitate his wife during the
1990s. However, the more general flaw in reasoning here is
an elementary one in ethics—seeking to discredit the per-
son making the decision instead of considering the merits
of the decision itself. The courts correctly avoided this ad
hominem fallacy, although many media commentators did
Securing individual liberties and honoring self-deter-
mination for oneself and others were the impetus for the
founding of the United States and have been a prominent
part of the American sensibility ever since. However, pro-
tecting the liberty interests of those who have lost compe-
tence was not always the favored framework for either law
or medical ethics (22). It has become so for both fields
through a series of momentous court decisions and
through changes in medical ethics that both prefigured the
court decisions and became codified in the wake of them.
For instance, the cases of Karen Ann Quinlan in 1976
(23), Paul Brophy in 1986 (24), and Nancy Cruzan in
1990 (25) all involved patients in the persistent vegetative
state who did not have written advance directives. In each
of these cases, the courts deemed the liberty and privacy
interests of the patient as paramount.
Likewise, medical codes of ethics echo this legal con-
sensus when they frame end-of-life issues in terms of au-
tonomy and affirm the right of patients to informed con-
sent and respect for their wishes, even beyond their loss of
competence, when it can be reasonably determined what
they would have wanted (26). Of course, to assert that
respect for self-determination is paramount does not mean
that it is the only principle at work in this and similar
cases—it also does not mean that discerning someone’s
preferences for medical care from the accounts of others is
simple or without problems. Rather, our claim is that using
self-determination as the primary framework is simply the
best we can do and is far less problematic than relying on
medical or parental beneficence, quality of life, or sanctity-
of-life judgments. Relying fundamentally on these other
norms would jeopardize the rights of Terri Schiavo and
patients like her to receive or not to receive continuing
interventions and would threaten this basic principle of
U.S. law and American medical ethics.
The Terri Schiavo case will probably remain contro-
versial, with some people feeling strongly that the wrong
decision was made. We have argued that, to the contrary,
this case is an example of good standards and processes in
medicine, law, and ethics. It exemplifies the use of medical
consensus to create standards to diagnose persistent vege-

tative state, it is characterized by careful proceedings and
review in keeping with a long tradition of legal procedure,
and it embodies respect for self-determination as a funda-
mental U.S. principle that honors both individual prefer-
ences and a wide moral pluralism.
