CRUZAN, by her parents and co-guardians, CRUZAN et ux. v. DIRECTOR, MISSOURI DEPARTMENT OF HEALTH, et al.

No. 881503

[June 25, 1990]

Justice Brennan, with whom Justice Marshall and Justice Blackmun join, dissenting.

"Medical technology has effectively created a twilight zone of suspended animation where death commences while life, in some form, continues. Some patients, however, want no part of a life sustained only by medical technology. Instead, they prefer a plan of medical treatment that allows nature to take its course and permits them to die with dignity."[n.1]

Nancy Cruzan has dwelt in that twilight zone for six years. She is oblivious to her surroundings and will remain so. Cruzan v. Harmon, 760 S.W. 2d 408, 411 (Mo. 1988). Her body twitches only reflexively, without consciousness. Ibid. The areas of her brain that once thought, felt, and experienced sensations have degenerated badly and are continuing to do so. The cavities remaining are filling with cerebro-spinal fluid. The "'cerebral cortical atrophy is irreversible, permanent, progressive and ongoing.'" Ibid. "Nancy will never interact meaningfully with her environment again. She will remain in a persistent vegetative state until her death." Id., at 422. [n.2] Because she cannot swallow, her nutrition and hydration are delivered through a tube surgically implanted in her stomach.

A grown woman at the time of the accident, Nancy had previously expressed her wish to forgo continuing medical care under circumstances such as these. Her family and her friends are convinced that this is what she would want. See n.20, infra. A guardian ad litem appointed by the trial court is also convinced that this is what Nancy would want. See 760 S.W. 2d, at 444 (Higgins, J., dissenting from denial of rehearing). Yet the Missouri Supreme Court, alone among state courts deciding such a question, has determined that an irreversibly vegetative patient will remain a passive prisoner of medical technologyfor Nancy, perhaps for the next 30 years. See id., at 424, 427.

Today the Court, while tentatively accepting that there is some degree of constitutionally protected liberty interest in avoiding unwanted medical treatment, including life-sustaining medical treatment such as artificial nutrition and hydration, affirms the decision of the Missouri Supreme Court. The majority opinion, as I read it, would affirm that decision on the ground that a State may require "clear and convincing" evidence of Nancy Cruzan's prior decision to forgo life-sustaining treatment under circumstances such as hers in order to ensure that her actual wishes are honored. See ante, at 1719, 22. Because I believe that Nancy Cruzan has a fundamental right to be free of unwanted artificial nutrition and hydration, which right is not outweighed by any interests of the State, and because I find that the improperly biased procedural obstacles imposed by the Missouri Supreme Court impermissibly burden that right, I respectfully dissent. Nancy Cruzan is entitled to choose to die with dignity.



"[T]he timing of deathonce a matter of fateis now a matter of human choice." Office of Technology Assessment Task Force, Life Sustaining Technologies and the Elderly 41 (1988). Of the approximately two million people who die each year, 80" die in hospitals and long-term care institutions, [n.3] and perhaps 70" of those after a decision to forgo life-sustaining treatment has been made. [n.4] Nearly every death involves a decision whether to undertake some medical procedure that could prolong the process of dying. Such decisions are difficult and personal. They must be made on the basis of individual values, informed by medical realities, yet within a framework governed by law. The role of the courts is confined to defining that framework, delineating the ways in which government may and may not participate in such decisions.

The question before this Court is a relatively narrow one: whether the Due Process Clause allows Missouri to require a now-incompetent patient in an irreversible persistent vegetative state to remain on life-support absent rigorously clear and convincing evidence that avoiding the treatment represents the patient's prior, express choice. See ante, at 13. If a fundamental right is at issue, Missouri's rule of decision must be scrutinized under the standards this Court has always applied in such circumstances. As we said in Zablocki v. Redhail, 434 U.S. 374, 388 (1978), if a requirement imposed by a State "significantly interferes with the exercise of a fundamental right, it cannot be upheld unless it is supported by sufficiently important state interests and is closely tailored to effectuate only those interests." The Constitution imposes on this Court the obligation to "examine carefully ... the extent to which [the legitimate government interests advanced] are served by the challenged regulation." Moore v. East Cleveland, 431 U.S. 494, 499 (1977). See also Carey v. Population Services International, 431 U.S. 678, 690 (1977) (invalidating a requirement that bore "no relation to the State's interest"). An evidentiary rule, just as a substantive prohibition, must meet these standards if it significantly burdens a fundamental liberty interest. Fundamental rights "are protected not only against heavy-handed frontal attack, but also from being stifled by more subtle governmental interference." Bates v. Little Rock, 361 U.S. 516, 523 (1960).


The starting point for our legal analysis must be whether a competent person has a constitutional right to avoid unwanted medical care. Earlier this Term, this Court held that the Due Process Clause of the Fourteenth Amendment confers a significant liberty interest in avoiding unwanted medical treatment. Washington v. Harper, 494 U.S. , (1990). Today, the Court concedes that our prior decisions "support the recognition of a general liberty interest in refusing medical treatment." See ante, at 14. The Court, however, avoids discussing either the measure of that liberty interest or its application by assuming, for purposes of this case only, that a competent person has a constitutionally protected liberty interest in being free of unwanted artificial nutrition and hydration. See ante, at 15. Justice O'Connor's opinion is less parsimonious. She openly affirms that "the Court has often deemed state incursions into the body repugnant to the interests protected by the Due Process Clause," that there is a liberty interest in avoiding unwanted medical treatment and that it encompasses the right to be free of "artificially delivered food and water." See ante, at 1.

But if a competent person has a liberty interest to be free of unwanted medical treatment, as both the majority and Justice O'connor concede, it must be fundamental. "We are dealing here with [a decision] which involves one of the basic civil rights of man." Skinner v. Oklahoma ex rel. Williamson, 316 U.S. 535, 541 (1942) (invalidating a statute authorizing sterilization of certain felons). Whatever other liberties protected by the Due Process Clause are fundamental, "those liberties that are 'deeply rooted in this Nation's history and tradition'" are among them. Bowers v. Hardwick, 478 U.S. 186, 192 (1986) (quoting Moore v. East Cleveland, supra, at 503 (plurality opinion). "Such a tradition commands respect in part because the Constitution carries the gloss of history." Richmond Newspapers, Inc. v. Virginia, 448 U.S. 555, 589 (1980) (Brennan, J., concurring in judgment).

The right to be free from medical attention without consent, to determine what shall be done with one's own body, is deeply rooted in this Nation's traditions, as the majority acknowledges. See ante, at 5. This right has long been "firmly entrenched in American tort law" and is securely grounded in the earliest common law. Ibid. See also Mills v. Rogers, 457 U.S. 291, 294, n.4 (1982) ("the right to refuse any medical treatment emerged from the doctrines of trespass and battery, which were applied to unauthorized touchings by a physician"). "'Anglo-American law starts with the premise of thorough-going self determination. It follows that each man is considered to be master of his own body, and he may, if he be of sound mind, expressly prohibit the performance of lifesaving surgery, or other medical treatment.'" Natanson v. Kline, 186 Kan. 393, 406407, 350 P. 2d 1093, 1104 (1960). "The inviolability of the person" has been held as "sacred" and "carefully guarded" as any common law right. Union Pacific R. Co. v. Botsford, 141 U.S. 250, 251252 (1891). Thus, freedom from unwanted medical attention is unquestionably among those principles "so rooted in the traditions and conscience of our people as to be ranked as fundamental." Snyder v. Massachusetts, 291 U.S. 97, 105 (1934). [n.5]

That there may be serious consequences involved in refusal of the medical treatment at issue here does not vitiate the right under our common law tradition of medical self-determination. It is "a well-established rule of general law ... that it is the patient, not the physician, who ultimately decides if treatmentany treatmentis to be given at all. ... The rule has never been qualified in its application by either the nature or purpose of the treatment, or the gravity of the consequences of acceding to or foregoing it." Tune v. Walter Reed Army Medical Hospital, 602 F. Supp. 1452, 1455 (DC 1985). See also Downer v. Veilleux, 322 A. 2d 82, 91 (Me. 1974) ("The rationale of this rule lies in the fact that every competent adult has the right to forego treatment, or even cure, if it entails what for him are intolerable consequences or risks, however unwise his sense of values may be to others"). [n.6]

No material distinction can be drawn between the treatment to which Nancy Cruzan continues to be subjectartificial nutrition and hydrationand any other medical treatment. See ante, at 2 (O'Connor, J., concurring). The artificial delivery of nutrition and hydration is undoubtedly medical treatment. The technique to which Nancy Cruzan is subjectartificial feeding through a gastrostomy tubeinvolves a tube implanted surgically into her stomach through incisions in her abdominal wall. It may obstruct the intestinal tract, erode and pierce the stomach wall or cause leakage of the stomach's contents into the abdominal cavity. See Page, Andrassy, & Sandler, Techniques in Delivery of Liquid Diets, in Nutrition in Clinical Surgery 6667 (M. Deitel 2d ed. 1985). The tube can cause pneumonia from reflux of the stomach's contents into the lung. See Bernard & Forlaw, Complications and Their Prevention, in Enteral and Tube Feeding 553 (J. Rombeau & M. Caldwell eds. 1984). Typically, and in this case (see Tr. 377), commercially prepared formulas are used, rather than fresh food. See Matarese, Enteral Alimentation, in Surgical Nutrition 726 (J. Fischer ed. 1983). The type of formula and method of administration must be experimented with to avoid gastrointestinal problems. Id., at 748. The patient must be monitored daily by medical personnel as to weight, fluid intake and fluid output; blood tests must be done weekly. Id., at 749, 751.

Artificial delivery of food and water is regarded as medical treatment by the medical profession and the Federal Government. [n.7] According to the American Academy of Neurology:

"The artificial provision of nutrition and hydration is a form of medical treatment ... analogous to other forms of life-sustaining treatment, such as the use of the respirator. When a patient is unconscious, both a respirator and an artificial feeding device serve to support or replace normal bodily functions that are compromised as a result of the patient's illness." Position of the American Academy of Neurology on Certain Aspects of the Care and Management of the Persistent Vegetative State Patient, 39 Neurology 125 (Jan. 1989). See also Council on Ethical and Judicial Affairs of the American Medical Association, Current Opinions, Opinion 2.20 (1989) ("Life-prolonging medical treatment includes medication and artifically or technologically supplied respiration, nutrition or hydration"); President's Commission 88 (life-sustaining treatment includes respirators, kidney dialysis machines, special feeding procedures). The Federal Government permits the cost of the medical devices and formulas used in enteral feeding to be reimbursed under Medicare. See Pub. L. 99509, 9340, note following 42 U.S.C. 1395u p.592 (1982 ed., Supp. V). The formulas are regulated by the Federal Drug Administration as "medical foods," see 21 U.S.C. 360ee and the feeding tubes are regulated as medical devices, 21 CFR 876.5980 (1989).

Nor does the fact that Nancy Cruzan is now incompetent deprive her of her fundamental rights. See Youngberg v. Romeo, 457 U.S. 307, 315316, 319 (1982) (holding that severely retarded man's liberty interests in safety, freedom from bodily restraint and reasonable training survive involuntary commitment); Parham v. J.R., 442 U.S. 584, 600 (1979) (recognizing a child's substantial liberty interest in not being confined unnecessarily for medical treatment); Jackson v. Indiana, 406 U.S. 715, 730, 738 (1972) (holding that Indiana could not violate the due process and equal protection rights of a mentally retarded deaf mute by committing him for an indefinite amount of time simply because he was incompetent to stand trial on the criminal charges filed against him). As the majority recognizes, ante, at 16, the question is not whether an incompetent has constitutional rights, but how such rights may be exercised. As we explained in Thompson v. Oklahoma, 487 U.S. 815 (1988), "[t]he law must often adjust the manner in which it affords rights to those whose status renders them unable to exercise choice freely and rationally. Children, the insane, and those who are irreversibly ill with loss of brain function, for instance, all retain 'rights,' to be sure, but often such rights are only meaningful as they are exercised by agents acting with the best interests of their principals in mind." Id., at 825, n.23 (emphasis added). "To deny [its] exercise because the patient is unconscious or incompetent would be to deny the right." Foody v. Manchester Memorial Hospital, 40 Conn. Super. 127, 133, 482 A. 2d 713, 718 (1984).



The right to be free from unwanted medical attention is a right to evaluate the potential benefit of treatment and its possible consequences according to one's own values and to make a personal decision whether to subject oneself to the intrusion. For a patient like Nancy Cruzan, the sole benefit of medical treatment is being kept metabolically alive. Neither artificial nutrition nor any other form of medical treatment available today can cure or in any way ameliorate her condition. [n.8] Irreversibly vegetative patients are devoid of thought, emotion and sensation; they are permanently and completely unconscious. See n.2, supra. [n.9] As the President's Commission concluded in approving the withdrawal of life support equipment from irreversibly vegetative patients:

"[T]reatment ordinarily aims to benefit a patient through preserving life, relieving pain and suffering, protecting against disability, and returning maximally effective functioning. If a prognosis of permanent unconsciousness is correct, however, continued treatment cannot confer such benefits. Pain and suffering are absent, as are joy, satisfaction, and pleasure. Disability is total and no return to an even minimal level of social or human functioning is possible." President's Commission 181 182.

There are also affirmative reasons why someone like Nancy might choose to forgo artificial nutrition and hydration under these circumstances. Dying is personal. And it is profound. For many, the thought of an ignoble end, steeped in decay, is abhorrent. A quiet, proud death, bodily integrity intact, is a matter of extreme consequence. "In certain, thankfully rare, circumstances the burden of maintaining the corporeal existence degrades the very humanity it was meant to serve." Brophy v. New England Sinai Hospital, Inc., 398 Mass. 417, 434, 497 N.E. 2d 626, 635636 (1986) (finding the subject of the proceeding "in a condition which [he] has indicated he would consider to be degrading and without human dignity" and holding that "[t]he duty of the State to preserve life must encompass a recognition of an individual's right to avoid circumstances in which the individual himself would feel that efforts to sustain life demean or degrade his humanity"). Another court, hearing a similar case, noted:

"It is apparent from the testimony that what was on [the patient's] mind was not only the invasiveness of life-sustaining systems, such as the [nasogastric] tube, upon the integrity of his body. It was also the utter helplessness of the permanently comatose person, the wasting of a once strong body, and the submission of the most private bodily functions to the attention of others." In re Gardner, 534 A. 2d 947, 953 (Me. 1987).

Such conditions are, for many, humiliating to contemplate, [n.10] as is visiting a prolonged and anguished vigil on one's parents, spouse, and children. A long, drawn-out death can have a debilitating effect on family members. See Carnwath & Johnson, Psychiatric Morbidity Among Spouses of Patients With Stroke, 294 Brit. Med. J. 409 (1987); Livingston, Families Who Care, 291 Brit. Med. J. 919 (1985). For some, the idea of being remembered in their persistent vegetative states rather than as they were before their illness or accident may be very disturbing. [n.11]


Although the right to be free of unwanted medical intervention, like other constitutionally protected interests, may not be absolute, [n.12] no State interest could outweigh the rights of an individual in Nancy Cruzan's position. Whatever a State's possible interests in mandating life-support treatment under other circumstances, there is no good to be obtained here by Missouri's insistence that Nancy Cruzan remain on life-support systems if it is indeed her wish not to do so. Missouri does not claim, nor could it, that society as a whole will be benefited by Nancy's receiving medical treatment. No third party's situation will be improved and no harm to others will be averted. Cf. nn.6 and 8, supra. [n.13]

The only state interest asserted here is a general interest in the preservation of life. [n.14] But the State has no legitimate general interest in someone's life, completely abstracted from the interest of the person living that life, that could outweigh the person's choice to avoid medical treatment. "[T]he regulation of constitutionally protected decisions ... must be predicated on legitimate state concerns other than disagreement with the choice the individual has made.... Otherwise, the interest in liberty protected by the Due Process Clause would be a nullity." Hodgson v. Minnesota, U.S. , (1990) (Opinion of Stevens, J.) (slip op., at 14) (emphasis added). Thus, the State's general interest in life must accede to Nancy Cruzan's particularized and intense interest in self-determination in her choice of medical treatment. There is simply nothing legitimately within the State's purview to be gained by superseding her decision.

Moreover, there may be considerable danger that Missouri's rule of decision would impair rather than serve any interest the State does have in sustaining life. Current medical practice recommends use of heroic measures if there is a scintilla of a chance that the patient will recover, on the assumption that the measures will be discontinued should the patient improve. When the President's Commission in 1982 approved the withdrawal of life support equipment from irreversibly vegetative patients, it explained that "[a]n even more troubling wrong occurs when a treatment that might save life or improve health is not started because the health care personnel are afraid that they will find it very difficult to stop the treatment if, as is fairly likely, it proves to be of little benefit and greatly burdens the patient." President's Commission 75. A New Jersey court recognized that families as well as doctors might be discouraged by an inability to stop life-support measures from "even attempting certain types of care [which] could thereby force them into hasty and premature decisions to allow a patient to die." In re Conroy, 98 N.J. 321, 370, 486 A. 2d 1209, 1234, (1985). See also Brief for American Academy of Neurology as Amicus Cruae 9 (expressing same concern). [n.15]


This is not to say that the State has no legitimate interests to assert here. As the majority recognizes, ante, at 17, Missouri has a parens patriae interest in providing Nancy Cruzan, now incompetent, with as accurate as possible a determination of how she would exercise her rights under these circumstances. Second, if and when it is determined that Nancy Cruzan would want to continue treatment, the State may legitimately assert an interest in providing that treatment. But until Nancy's wishes have been determined, the only state interest that may be asserted is an interest in safeguarding the accuracy of that determination.

Accuracy, therefore, must be our touchstone. Missouri may constitutionally impose only those procedural requirements that serve to enhance the accuracy of a determination of Nancy Cruzan's wishes or are at least consistent with an accurate determination. The Missouri "safeguard" that the Court upholds today does not meet that standard. The determination needed in this context is whether the incompetent person would choose to live in a persistent vegetative state on life-support or to avoid this medical treatment. Missouri's rule of decision imposes a markedly asymmetrical evidentiary burden. Only evidence of specific statements of treatment choice made by the patient when competent is admissible to support a finding that the patient, now in a persistent vegetative state, would wish to avoid further medical treatment. Moreover, this evidence must be clear and convincing. No proof is required to support a finding that the incompetent person would wish to continue treatment.


The majority offers several justifications for Missouri's heightened evidentiary standard. First, the majority explains that the State may constitutionally adopt this rule to govern determinations of an incompetent's wishes in order to advance the State's substantive interests, including its unqualified interest in the preservation of human life. See ante, at 1718, and n.10. Missouri's evidentiary standard, however, cannot rest on the State's own interest in a particular substantive result. To be sure, courts have long erected clear and convincing evidence standards to place the greater risk of erroneous decisions on those bringing disfavored claims. [n.16] In such cases, however, the choice to discourage certain claims was a legitimate, constitutional policy choice. In contrast, Missouri has no such power to disfavor a choice by Nancy Cruzan to avoid medical treatment, because Missouri has no legitimate interest in providing Nancy with treatment until it is established that this represents her choice. See supra, at 1314. Just as a State may not override Nancy's choice directly, it may not do so indirectly through the imposition of a procedural rule.

Second, the majority offers two explanations for why Missouri's clear and convincing evidence standard is a means of enhancing accuracy, but neither is persuasive. The majority initially argues that a clear and convincing evidence standard is necessary to compensate for the possibility that such proceedings will lack the "guarantee of accurate factfinding that the adversary process brings with it," citing Ohio v. Akron Center for Reproductive Health, U.S. , (1990) (upholding a clear and convincing evidence standard for an ex parte proceeding). Ante, at 17. Without supporting the Court's decision in that case, I note that the proceeding to determine an incompetent's wishes is quite different from a proceeding to determine whether a minor may bypass notifying her parents before undergoing an abortion on the ground that she is mature enough to make the decision or that the abortion is in her best interests.

An adversarial proceeding is of particular importance when one side has a strong personal interest which needs to be counterbalanced to assure the court that the questions will be fully explored. A minor who has a strong interest in obtaining permission for an abortion without notifying her parents may come forward whether or not society would be satisfied that she has made the decision with the seasoned judgment of an adult. The proceeding here is of a different nature. Barring venal motives, which a trial court has the means of fer reting out, the decision to come forward to request a judicial order to stop treatment represents a slowly and carefully considered resolution by at least one adult and more frequently several adults that discontinuation of treatment is the patient's wish.

In addition, the bypass procedure at issue in Akron, supra, is ex parte and secret. The court may not notify the minor's parents, siblings or friends. No one may be present to submit evidence unless brought forward by the minor herself. In contrast, the proceeding to determine Nancy Cruzan's wishes was neither ex parte nor secret. In a hearing to determine the treatment preferences of an incompetent person, a court is not limited to adjusting burdens of proof as its only means of protecting against a possible imbalance. Indeed, any concern that those who come forward will present a one-sided view would be better addressed by appointing a guardian ad litem, who could use the State's powers of discovery to gather and present evidence regarding the patient's wishes. A guardian ad litem's task is to uncover any conflicts of interest and ensure that each party likely to have relevant evidence is consulted and brought forwardfor example, other members of the family, friends, clergy, and doctors. See, e.g., In re Colyer, 99 Wash. 2d 114, 133, 660 P. 2d 738, 748749 (1983). Missouri's heightened evidentiary standard attempts to achieve balance by discounting evidence; the guardian ad litem technique achieves balance by probing for additional evidence. Where, as here, the family members, friends, doctors and guardian ad litem agree, it is not because the process has failed, as the majority suggests. See ante, at 17, n.9. It is because there is no genuine dispute as to Nancy's preference.

The majority next argues that where, as here, important individual rights are at stake, a clear and convincing evidence standard has long been held to be an appropriate means of enhancing accuracy, citing decisions concerning what process an individual is due before he can be deprived of a liberty interest. See ante, at 1819. In those cases, however, this Court imposed a clear and convincing standard as a constitutional minimum on the basis of its evaluation that one side's interests clearly outweighed the second side's interests and therefore the second side should bear the risk of error. See Santosky v. Kramer, 455 U.S. 745, 753, 766767 (1982) (requiring a clear and convincing evidence standard for termination of parental rights because the parent's interest is fundamental but the State has no legitimate interest in termination unless the parent is unfit, and finding that the State's interest in finding the best home for the child does not arise until the parent has been found unfit); Addington v. Texas, 441 U.S. 418, 426427 (1979) (requiring clear and convincing evidence in an involuntary commitment hearing because the interest of the individual far outweighs that of a State, which has no legitimate interest in confining individuals who are not mentally ill and do not pose a danger to themselves or others). Moreover, we have always recognized that shifting the risk of error reduces the likelihood of errors in one direction at the cost of increasing the likelihood of errors in the other. See Addington, supra, at 423 (contrasting heightened standards of proof to a preponderance standard in which the two sides "share the risk of error in roughly equal fashion" because society does not favor one outcome over the other). In the cases cited by the majority, the imbalance imposed by a heightened evidentiary standard was not only acceptable but required because the standard was deployed to protect an individual's exercise of a fundamental right, as the majority admits, ante, at 18, n.10. In contrast, the Missouri court imposed a clear and convincing standard as an obstacle to the exercise of a fundamental right.

The majority claims that the allocation of the risk of error is justified because it is more important not to terminate life-support for someone who would wish it continued than to honor the wishes of someone who would not. An erroneous decision to terminate life-support is irrevocable, says the majority, while an erroneous decision not to terminate "results in a maintenance of the status quo." See ante, at 19. [n.17] But, from the point of view of the patient, an erroneous decision in either direction is irrevocable. An erroneous decision to terminate artificial nutrition and hydration, to be sure, will lead to failure of that last remnant of physiological life, the brain stem, and result in complete brain death. An erroneous decision not to terminate life-support, however, robs a patient of the very qualities protected by the right to avoid unwanted medical treatment. His own degraded existence is perpetuated; his family's suffering is protracted; the memory he leaves behind becomes more and more distorted.

Even a later decision to grant him his wish cannot undo the intervening harm. But a later decision is unlikely in any event. "[T]he discovery of new evidence," to which the majority refers, ibid., is more hypothetical than plausible. The majority also misconceives the relevance of the possibility of "advancements in medical science," ibid., by treating it as a reason to force someone to continue medical treatment against his will. The possibility of a medical miracle is indeed part of the calculus, but it is a part of the patient's calculus. If current research suggests that some hope for cure or even moderate improvement is possible within the life-span projected, this is a factor that should be and would be accorded significant weight in assessing what the patient himself would choose. [n.18]


Even more than its heightened evidentiary standard, the Missouri court's categorical exclusion of relevant evidence dispenses with any semblence of accurate factfinding. The court adverted to no evidence supporting its decision, but held that no clear and convincing, inherently reliable evidence had been presented to show that Nancy would want to avoid further treatment. In doing so, the court failed to consider statements Nancy had made to family members and a close friend. [n.19] The court also failed to consider testimony from Nancy's mother and sister that they were certain that Nancy would want to discontinue to artificial nutrition and hydration, [n.20] even after the court found that Nancy's family was loving and without malignant motive. See 760 S.W. 2d, at 412. The court also failed to consider the conclusions of the guardian ad litem, appointed by the trial court, that there was clear and convincing evidence that Nancy would want to discontinue medical treatment and that this was in her best interests. Id., at 444 (Higgins, J., dissenting from denial of rehearing); Brief for Respondent Guardian Ad Litem 23. The court did not specifically define what kind of evidence it would consider clear and convincing, but its general discussion suggests that only a living will or equivalently formal directive from the patient when competent would meet this standard. See 760 S.W. 2d, at 424-425.

Too few people execute living wills or equivalently formal directives for such an evidentiary rule to ensure adequately that the wishes of incompetent persons will be honored. [n.21] While it might be a wise social policy to encourage people to furnish such instructions, no general conclusion about a patient's choice can be drawn from the absence of formalities. The probability of becoming irreversibly vegetative is so low that many people may not feel an urgency to marshal formal evidence of their preferences. Some may not wish to dwell on their own physical deterioration and mortality. Even someone with a resolute determination to avoid life-support under circumstances such as Nancy's would still need to know that such things as living wills exist and how to execute one. Often legal help would be necessary, especially given the majority's apparent willingness to permit States to insist that a person's wishes are not truly known unless the particular medical treatment is specified. See ante, at 21.

As a California appellate court observed: "The lack of generalized public awareness of the statutory scheme and the typically human characteristics of procrastination and reluctance to contemplate the need for such arrangements however makes this a tool which will all too often go unused by those who might desire it." Barber v. Superior Court, 147 Cal. App. 3d 1006, 1015, 194 Cal. Rptr. 484, 489 (1983). When a person tells family or close friends that she does not want her life sustained artificially, she is "express[ing] her wishes in the only terms familiar to her, and ... as clearly as a lay person should be asked to express them. To require more is unrealistic, and for all practical purposes, it precludes the rights of patients to forego life-sustaining treatment." In re O'Connor, 72 N.Y. 2d 517, 551, 531 N.E. 2d 607, 626 (1988) (Simons, J., dissenting). [n.22] When Missouri enacted a living will statute, it specifically provided that the absence of a living will does not warrant a presumption that a patient wishes continued medical treatment. See n.15, supra. Thus, apparently not even Missouri's own legislature believes that a person who does not execute a living will fails to do so because he wishes continuous medical treatment under all circumstances.

The testimony of close friends and family members, on the other hand, may often be the best evidence available of what the patient's choice would be. It is they with whom the patient most likely will have discussed such questions and they who know the patient best. "Family members have a unique knowledge of the patient which is vital to any decision on his or her behalf." Newman, Treatment Refusals for the Critically and Terminally Ill: Proposed Rules for the Family, the Physician, and the State, 3 N.Y.L.S. Human Rights Annual 35, 46 (1985). The Missouri court's decision to ignore this whole category of testimony is also at odds with the practices of other States. See, e.g., In re Peter, 108 N.J. 365, 529 A. 2d 419 (1987), Brophy v. New England Sinai Hospital, Inc., 398 Mass. 417, 497 N.E. 2d 626 (1986); In re Severns, 425 A. 2d 156 (Del. Ch. 1980).

The Missouri court's disdain for Nancy's statements in serious conversations not long before her accident, for the opinions of Nancy's family and friends as to her values, beliefs and certain choice, and even for the opinion of an outside objective factfinder appointed by the State evinces a disdain for Nancy Cruzan's own right to choose. The rules by which an incompetent person's wishes are determined must represent every effort to determine those wishes. The rule that the Missouri court adopted and that this Court upholds, however, skews the result away from a determination that as accurately as possible reflects the individual's own preferences and beliefs. It is a rule that transforms human beings into passive subjects of medical technology.

"[M]edical care decisions must be guided by the individual patient's interests and values. Allowing persons to determine their own medical treatment is an important way in which society respects persons as individuals. Moreover, the respect due to persons as individuals does not diminish simply because they have become incapable of participating in treatment decisions.... [I]t is still possible for others to make a decision that reflects [the patient's] interests more closely than would a purely technological decision to do whatever is possible. Lacking the ability to decide, [a patient] has a right to a decision that takes his interests into account." In re Drabick, 200 Cal. App. 3d 185, 208; 245 Cal. Rptr. 840, 854855 (1988).


I do not suggest that States must sit by helplessly if the choices of incompetent patients are in danger of being ignored. See ante, at 17. Even if the Court had ruled that Missouri's rule of decision is unconstitutional, as I believe it should have, States would nevertheless remain free to fashion procedural protections to safeguard the interests of incompetents under these circumstances. The Constitution provides merely a framework here: protections must be genuinely aimed at ensuring decisions commensurate with the will of the patient, and must be reliable as instruments to that end. Of the many States which have instituted such protections, Missouri is virtually the only one to have fashioned a rule that lessens the likelihood of accurate determinations. In contrast, nothing in the Constitution prevents States from reviewing the advisability of a family decision, by requiring a court proceeding or by appointing an impartial guardian ad litem.

There are various approaches to determining an incompetent patient's treatment choice in use by the several States today and there may be advantages and disadvantages to each and other approaches not yet envisioned. The choice, in largest part, is and should be left to the States, so long as each State is seeking, in a reliable manner, to discover what the patient would want. But with such momentous interests in the balance, States must avoid procedures that will prejudice the decision. "To err either wayto keep a person alive under circumstances under which he would rather have been allowed to die, or to allow that person to die when he would have chosen to cling to lifewould be deeply unfortunate." In re Conroy, 98 N.J., at 343, 486 A. 2d, at 1220.


Finally, I cannot agree with the majority that where it is not possible to determine what choice an incompetent patient would make, a State's role as parens patriae permits the State automatically to make that choice itself. See ante, at 22 (explaining that the Due Process Clause does not require a State to confide the decision to "anyone but the patient herself"). Under fair rules of evidence, it is improbable that a court could not determine what the patient's choice would be. Under the rule of decision adopted by Missouri and upheld today by this Court, such occasions might be numerous. But in neither case does it follow that it is constitutionally acceptable for the State invariably to assume the role of deciding for the patient. A State's legitimate interest in safeguarding a patient's choice cannot be furthered by simply appropriating it.

The majority justifies its position by arguing that, while close family members may have a strong feeling about the question, "there is no automatic assurance that the view of close family members will necessarily be the same as the patient's would have been had she been confronted with the prospect of her situation while competent." Ibid. I cannot quarrel with this observation. But it leads only to another question: Is there any reason to suppose that a State is more likely to make the choice that the patient would have made than someone who knew the patient intimately? To ask this is to answer it. As the New Jersey Supreme Court observed: "Family members are best qualified to make substituted judgments for incompetent patients not only because of their peculiar grasp of the patient's approach to life, but also because of their special bonds with him or her.... It is ... they who treat the patient as a person, rather than a symbol of a cause." In re Jobes, 108 N.J. 394, 416, 529 A. 2d 434, 445 (1987). The State, in contrast, is a stranger to the patient.

A State's inability to discern an incompetent patient's choice still need not mean that a State is rendered powerless to protect that choice. But I would find that the Due Process Clause prohibits a State from doing more than that. A State may ensure that the person who makes the decision on the patient's behalf is the one whom the patient himself would have selected to make that choice for him. And a State may exclude from consideration anyone having improper motives. But a State generally must either repose the choice with the person whom the patient himself would most likely have chosen as proxy or leave the decision to the patient's family. [n.23]


As many as 10,000 patients are being maintained in persistent vegetative states in the United States, and the number is expected to increase significantly in the near future. See Cranford, supra n.2, at 27, 31. Medical technology, developed over the past 20 or so years, is often capable of resuscitating people after they have stopped breathing or their hearts have stopped beating. Some of those people are brought fully back to life. Two decades ago, those who were not and could not swallow and digest food, died. Intravenous solutions could not provide sufficient calories to maintain people for more than a short time. Today, various forms of artificial feeding have been developed that are able to keep people metabolically alive for years, even decades. See Spencer & Palmisano, Specialized Nutritional Support of PatientsA Hospital's Legal Duty?, 11 Quality Rev. Bull. 160, 160161 (1985). In addition, in this century, chronic or degenerative ailments have replaced communicable diseases as the primary causes of death. See R. Weir, Abating Treatment with Critically Ill Patients 1213 (1989); President's Commission 1516. The 80" of Americans who die in hospitals are "likely to meet their end ... 'in a sedated or comatose state; betubed nasally, abdominally and intravenously; and far more like manipulated objects than like moral subjects.'" [n.24] A fifth of all adults surviving to age 80 will suffer a progressive dementing disorder prior to death. See Cohen & Eisdorfer, Dementing Disorders, in The Practice of Geriatrics 194 (E. Calkins, P. Davis, & A, Ford eds. 1986).

"[L]aw, equity and justice must not themselves quail and be helpless in the face of modern technological marvels presenting questions hitherto unthought of." In re Quinlan, 70 N.J. 10, 44, 355 A. 2d 647, 665, cert. denied, 429 U.S. 922 (1976). The new medical technology can reclaim those who would have been irretrievably lost a few decades ago and restore them to active lives. For Nancy Cruzan, it failed, and for others with wasting incurable disease it may be doomed to failure. In these unfortunate situations, the bodies and preferences and memories of the victims do not escheat to the State; nor does our Constitution permit the State or any other government to commandeer them. No singularity of feeling exists upon which such a government might confidently rely as parens patriae. The President's Commission, after years of research, concluded:

"In few areas of health care are people's evaluations of their experiences so varied and uniquely personal as in their assessments of the nature and value of the processes associated with dying. For some, every moment of life is of inestimable value; for others, life without some desired level of mental or physical ability is worthless or burdensome. A moderate degree of suffering may be an important means of personal growth and religious experience to one person, but only frightening or despicable to another." President's Commission 276.

Yet Missouri and this Court have displaced Nancy's own assessment of the processes associated with dying. They have discarded evidence of her will, ignored her values, and deprived her of the right to a decision as closely approximating her own choice as humanly possible. They have done so disingenuously in her name, and openly in Missouri's own. That Missouri and this Court may truly be motivated only by concern for incompetent patients makes no matter. As one of our most prominent jurists warned us decades ago: "Experience should teach us to be most on our guard to protect liberty when the government's purposes are beneficent.... The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well meaning but without understanding." Olmstead v. United States, 277 U.S. 438, 479 (1928) (Brandeis, J., dissenting).

I respectfully dissent.

6 Under traditional tort law, exceptions have been found only to protect dependent children. See Cruzan v. Harmon, 760 S.W. 2d 408, 422, n.17 (Mo. 1988) (citing cases where Missouri courts have ordered blood transfusions for children over the religious objection of parents); see also Winthrop University Hospital v. Hess, 128 Misc. 2d 804, 490 N.Y.S. 2d 996 (Sup. Ct. Nassau Co. 1985) (court ordered blood transfusion for religious objector because she was the mother of an infant and had explained that her objection was to the signing of the consent, not the transfusion itself); Application of President & Directors of Georgetown College, Inc., 118 U.S. App. D.C. 80, 88, 331 F. 2d 1000, 1008, cert. denied, 377 U.S. 978 (1964) (blood transfusion ordered for mother of infant). Cf. In re Estate of Brooks, 32 Ill. 2d 361, 373, 205 N.E. 2d 435, 441-442 (1965) (finding that lower court erred in ordering a blood transfusion for a woman — whose children were grown — and concluding: "Even though we may consider apellant's beliefs unwise, foolish or ridiculous, in the absence of an overriding danger to society we may not permit interference therewith in the form of a conservatorship established in the waning hours of her life for the sole purpose of compelling her to accept medical treatment forbidden by her religious principles, and previously refused by her with full knowledge of the probable consequences").

7 The Missouri court appears to be alone among state courts to suggest otherwise, 760 S.W. 2d, at 419 and 423, although the court did not rely on a distinction between artificial feeding and other forms of medical treatment. Id., at 423. See, e.g., Delio v. Westchester County Medical Center, 129 App. Div. 2d 1, 19, 516 N.Y.S. 2d 677, 689 (1987) ("review of the decisions in other jurisdictions ... failed to uncover a single case in which a court confronted with an application to discontinue feeding by artificial means has evaluated medical procedures to provide nutrition and hydration differently from other types of life-sustaining procedures").

8 While brain stem cells can survive 15 to 20 minutes without oxygen, cells in the cerebral hemispheres are destroyed if they are deprived of oxygen for as few as 4 to 6 minutes. See Cranford & Smith, Some Critical Distinctions Between Brain Death and the Persistent Vegetative State, 6 Ethics Sci. & Med. 199, 203 (1979). It is estimated that Nancy's brain was deprived of oxygen from 12 to 14 minutes. See ante, at 2. Out of the 100,000 patients who, like Nancy, have fallen into persistive vegetative states in the past 20 years due to loss of oxygen to the brain, there have been only three even partial recoveries documented in the medical literature. Brief for American Medical Association et al. as Amici Curiae 11-12. The longest any person has ever been in a persistent vegetative state and recovered was 22 months. See Snyder, Cranford, Rubens, Bundlie, & Rockswold, Delayed Recovery from Postanoxic Persistent Vegetative State, 14 Annals Neurol. 156 (1983). Nancy has been in this state for seven years.

9 The American Academy of Neurology offers three independent bases on which the medical profession rests these neurological conclusions:

"First, direct clinical experience with these patients demonstrates that there is no behavioral indication of any awareness of pain or suffering.

"Second, in all persistent vegetative state patients studied to date, post-mortem examination reveals overwhelming bilateral damage to the cerebral hemispheres to a degree incompatible with consciousness ....

"Third, recent data utilizing positron emission tomography indicates that the metabolic rate for glucose in the cerebral cortex is greatly reduced in persistent vegetative state patients, to a degree incompatible with consciousness." Position of the American Academy of Neurology on Certain Aspects of the Care and Management of the Persistent Vegetative State Patient, 39 Neurology 125 (Jan. 1989).

10 Nancy Cruzan, for instance, is totally and permanently disabled. All four of her limbs are severely contracted; her fingernails cut into her wrists. App. to Pet. for Cert. A93. She is incontinent of bowel and bladder. The most intimate aspects of her existence are exposed to and controlled by strangers. Brief for Respondent Guardian Ad Litem 2. Her family is convinced that Nancy would find this state degrading. See n.20, infra.

11 What general information exists about what most people would choose or would prefer to have chosen for them under these circumstances also indicates the importance of ensuring a means for now-incompetent patients to exercise their right to avoid unwanted medical treatment. A 1988 poll conducted by the American Medical Association found that 80" of those surveyed favored withdrawal of life support systems from hopelessly ill or irreversibly comatose patients if they or their families requested it. New York Times, June 5, 1988, p.14, col. 4 (citing American Medical News, June 3, 1988, p.9, col. 1). Another 1988 poll conducted by the Colorado University Graduate School of Public Affairs showed that 85" of those questioned would not want to have their own lives maintained with artificial nutrition and hydration if they became permanently unconscious. The Coloradoan, Sept. 29, 1988, p.1.

Such attitudes have been translated into considerable political action. Since 1976, 40 States and the District of Columbia have enacted natural death acts, expressly providing for self-determination under some or all of these situations. See Brief for Society for the Right to Die, Inc. as Amicus Curiae 8; Weiner, Privacy, Family, and Medical Decision Making for Persistent Vegetative Patients, 11 Cardozo L. Rev. 713, 720 (1990). Thirteen States and the District of Columbia have enacted statutes authorizing the appointment of proxies for making health care decisions. See ante, at 4, n.2 (O'Connor, J., concurring).

12 See Jacobson v. Massachusetts, 197 U.S. 11, 26-27 (1905) (upholding a Massachusetts law imposing fines or imprisonment on those refusing to be vaccinated as "of paramount necessity" to that State's fight against a smallpox epidemic).

13 Were such interests at stake, however, I would find that the Due Process Clause places limits on what invasive medical procedures could be forced on an unwilling comatose patient in pursuit of the interests of a third party. If Missouri were correct that its interests outweigh Nancy's interest in avoiding medical procedures as long as she is free of pain and physical discomfort, see 760 S.W. 2d, at 424, it is not apparent why a State could not choose to remove one of her kidneys without consent on the ground that society would be better off if the recipient of that kidney were saved from renal poisoning. Nancy cannot feel surgical pain. See n.2, supra. Nor would removal of one kidney be expected to shorten her life expectancy. See The American Medical Association Family Medical Guide 506 (J. Kunz ed. 1982). Patches of her skin could also be removed to provide grafts for burn victims, and scrapings of bone marrow to provide grafts for someone with leukemia. Perhaps the State could lawfully remove more vital organs for transplanting into others who would then be cured of their ailments, provided the State placed Nancy on some other life-support equipment to replace the lost function. Indeed, why could the State not perform medical experiments on her body, experiments that might save countless lives, and would cause her no greater burden than she already bears by being fed through the gastrostomy tube? This would be too brave a new world for me and, I submit, for our Constitution.

14 The Missouri Supreme Court reviewed the state interests that had been identified by other courts as potentially relevant — prevention of homicide and suicide, protection of interests of innocent third parties, maintenance of the ethical integrity of the medical profession, and preservation of life — and concluded that: "In this case, only the state's interest in the preservation of life is implicated." 760 S.W. 2d, at 419.

15 In any event, the State interest identified by the Missouri Supreme Court — a comprehensive and "unqualified" interest in preserving life, id., at 420, 424is not even well supported by that State's own enactments. In the first place, Missouri has no law requiring every person to procure any needed medical care nor a state health insurance program to underwrite such care. Id., at 429 (Blackmar, J., dissenting). Second, as the state court admitted, Missouri has a living will statute which specifically "allows and encourages the pre-planned termination of life." Ibid.; see Mo. Rev. Stat. 459.015(1) (1986). The fact that Missouri actively provides for its citizens to choose a natural death under certain circumstances suggests that the State's interest in life is not so unqualified as the court below suggests. It is true that this particular statute does not apply to nonterminal patients and does not include artificial nutrition and hydration as one of the measures that may be declined. Nonetheless, Missouri has also not chosen to require court review of every decision to withhold or withdraw life-support made on behalf of an incompetent patient. Such decisions are made every day, without state participation. See 760 S.W. 2d, at 428 (Blackmar, J., dissenting).

In addition, precisely what implication can be drawn from the statute's limitations is unclear given the inclusion of a series of "interpretive" provisions in the Act. The first such provision explains that the Act is to be interpreted consistently with the following: "Each person has the primary right to request or refuse medical treatment subject to the state's interest in protecting innocent third parties, preventing homicide and suicide and preserving good ethical standards in the medical profession." Mo. Rev. Stat. 459.055(1) (1986). The second of these subsections explains that the Act's provisions are cumulative and not intended to increase or decrease the right of a patient to make decisions or lawfully effect the withholding or withdrawal of medical care. 459.055(2). The third subsection provides that "no presumption concerning the intention of an individual who has not executed a declaration to consent to the use or withholding of medical procedures" shall be created. 459.055(3).

Thus, even if it were conceivable that a State could assert an interest sufficiently compelling to overcome Nancy Cruzan's constitutional right, Missouri law demonstrates a more modest interest at best. See generally Capital Cities Cable, Inc. v. Crisp, 467 U.S. 691, 715 (1984) (finding that state regulations narrow in scope indicated that State had only a moderate interest in its professed goal).

16 See Colorado v. New Mexico, 467 U.S. 310 (1984) (requiring clear and convincing evidence before one State is permitted to divert water from another to accommodate society's interests in stabile property rights and efficient use of resources); New York v. New Jersey, 256 U.S. 296 (1921) (promoting federalism by requiring clear and convincing evidence before using Court's power to control the conduct of one State at the behest of another); Maxwell Land-Grant Case, 121 U.S. 325 (1887) (requiring clear, unequivocal, and convincing evidence to set aside, annul or correct a patent or other title to property issued by the Government in order to secure settled expectations concerning property rights); Marcum v. Zaring, 406 P. 2d 970 (Okla. 1965) (promoting stability of marriage by requiring clear and convincing evidence to prove its invalidity); Stevenson v. Stein, 412 Pa. 478, 195 A. 2d 268 (1963) (promoting settled expectations concerning property rights by requiring clear and convincing evidence to prove adverse possession).

17 The majority's definition of the "status quo," of course, begs the question. Artificial delivery of nutrition and hydration represents the "status quo" only if the State has chosen to permit doctors and hospitals to keep a patient on life-support systems over the protests of his family or guardian. The "status quo" absent that state interference would be the natural result of his accident or illness (and the family's decision). The majority's definition of status quo, however, is "to a large extent a predictable, yet accidental confluence of technology, psyche, and inertia. The general citizenry ... never said that it favored the creation of coma wards where permanently unconscious patients would be tended for years and years. Nor did the populace as a whole authorize the preeminence of doctors over families in making treatment decisions for incompetent patients." Rhoden, Litigating Life and Death, 102 Harv. L. Rev. 375, 433-434 (1988).

18 For Nancy Cruzan, no such cure or improvement is in view. So much of her brain has deteriorated and been replaced by fluid, see App. to Pet. for Cert. A94, that apparently the only medical advance that could restore consciousness to her body would be a brain transplant. Cf. n.22, infra.

19 The trial court had relied on the testimony of Athena Comer, a long-time friend, co-worker and a housemate for several months, as sufficient to show that Nancy Cruzan would wish to be free of medical treatment under her present circumstances. App. to Pet. for Cert. A94. Ms. Comer described a conversation she and Nancy had while living together, concerning Ms. Comer's sister who had become ill suddenly and died during the night. The Comer family had been told that if she had lived through the night, she would have been in a vegetative state. Nancy had lost a grandmother a few months before. Ms. Comer testified that: "Nancy said she would never want to live [as a vegetative state] because if she couldn't be normal or even, you know, like half way, and do things for yourself, because Nancy always did, that she didn't want to live ... and we talked about it a lot." Tr. 388-389. She said "several times" that "she wouldn't want to live that way because if she was going to live, she wanted to be able to live, not to just lay in a bed and not be able to move because you can't do anything for yourself." Id., at 390, 396. "[S]he said that she hoped that [all the] people in her family knew that she wouldn't want to live [as a vegetable] because she knew it was usually up to the family whether you lived that way or not." Id., at 399.

The conversation took place approximately a year before Nancy's accident and was described by Ms. Comer as a "very serious" conversation that continued for approximately half an hour without interruption. Id., at 390. The Missouri Supreme Court dismissed Nancy's statement as "unreliable" on the ground that it was an informally expressed reaction to other people's medical conditions. 760 S.W. 2d, at 424.

The Missouri Supreme Court did not refer to other evidence of Nancy's wishes or explain why it was rejected. Nancy's sister Christy, to whom she was very close, testified that she and Nancy had had two very serious conversations about a year and a half before the accident. A day or two after their niece was stillborn (but would have been badly damaged if she had lived), Nancy had said that maybe it was part of a "greater plan" that the baby had been stillborn and did not have to face "the possible life of mere existence." Tr. 537. A month later, after their grandmother had died after a long battle with heart problems, Nancy said that "it was better for my grandmother not to be kind of brought back and forth [by] medical [treatment], brought back from a critical near point of death .... Id., at 541.

20 Nancy's sister Christy, Nancy's mother, and another of Nancy's friends testified that Nancy would want to discontinue the hydration and nutrition. Christy said that "Nancy would be horrified at the state she is in." Id., at 535. She would also "want to take that burden away from [her family]. Id., at 544. Based on "a lifetime of experience [I know Nancy's wishes] are to discontinue the hydration and the nutrition." Id., at 542. Nancy's mother testified: "Nancy would not want to be like she is now. [I]f it were me up there or Christy or any of us, she would be doing for us what we are trying to do for her. I know she would,... as her mother." Id., at 526.

21 Surveys show that the overwhelming majority of Americans have not executed such written instructions. See Emmanuel & Emmanuel, The Medical Directive: A New Comprehensive Advance Care Document, 261 JAMA 3288 (1989) (only 9" of Americans execute advance directives about how they would wish treatment decisions to be handled if they became incompetent); American Medical Association Surveys of Physician and Public Opinion on Health Care Issues 29-30 (1988) (only 15" of those surveyed had executed living wills); 2 President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research, Making Health Care Decisions 241-242 (1982) (23" of those surveyed said that they had put treatment instructions in writing).

22 New York is the only State besides Missouri to deny a request to terminate life support on the ground that clear and convincing evidence of prior, expressed intent was absent, although New York did so in the context of very different situations. Mrs. O'Connor, the subject of In re O'Connor, had several times expressed her desire not to be placed on life-support if she were not going to be able to care for herself. However, both of her daughters testified that they did not know whether their mother would want to decline artificial nutrition and hydration under her present circumstances. Cf. n.13, supra. Moreover, despite damage from several strokes, Mrs. O'Connor was conscious and capable of responding to simple questions and requests and the medical testimony suggested she might improve to some extent. Cf. supra, at 1. The New York Court of Appeals also denied permission to terminate blood transfusions for a severely retarded man with terminal cancer because there was no evidence of a treatment choice made by the man when competent, as he had never been competent. See In re Storar, 52 N.Y. 2d 363, 420 N.E. 2d 64, cert. denied, 454 U.S. 858 (1981). Again, the court relied on evidence that the man was conscious, functioning in the way he always had, and that the transfusions did not cause him substantial pain (although it was clear he did not like them).

23 Only in the exceedingly rare case where the State cannot find any family member or friend who can be trusted to endeavor genuinely to make the treatment choice the patient would have made does the State become the legitimate surrogate decisionmaker.
