IN THE MATTER OF MARY MOE.

LIACOS, J. The Probate Court for Worcester County appointed Ann Moe the guardian of her mentally retarded daughter, Mary Moe, on July 28, 1978. On April 1, 1980, the guardian petitioned the court, seeking an order permitting an abdominal tubal ligation (sterilization) to be performed on her ward. The petition alleged that although the ward is of legal age, she "is a mentally retarded person, whose chronological age does not conform with her emotional, intellectual, or developmental age and, upon facts and circumstances in the knowledge of your petitioner, and in the knowledge of professional in the Health Care Field, it would be in the best interest of the ward to have an abdominal tubal ligation."

On May 23, 1980, the probate judge appointed a guardian ad litem. The guardian ad litem filed an "objection to abdominal tubal ligation" on September 2, 1980, expressing his belief that, although sterilization would be in the ward's best interest, there was no apparent legal authority for the probate judge to authorize the requested procedure. The probate judge then appointed another attorney as counsel for the ward, while requesting the former attorney to remain as guardian ad litem.

On February 11, 1981, the ward's attorney filed a motion to dismiss the sterilization petition for lack of subject matter jurisdiction and failure to state a claim upon which relief could be granted. Mass. R. Civ. P. 12 (b) (1), (6), 365 Mass. 754 (1974). Among other grounds, the motion alleged that absent specific statutory authority, the probate judge could not order the sterilization of a mentally retarded person. The ward's attorney also moved that the probate judge reserve and report the questions of law raised by the motion to dismiss, before further proceedings ensued.

On March 16, 1981, the judge reported the matter, without decision, to the Appeals Court. G. L. c. 215, Section 13. Two questions were reported: "1. Can the probate and family

Page 557

court, absent specific statutory authority, order sterilization of an adult mentally retarded female; and 2. If the response to question one is in the affirmative, what procedures and standards should be followed and applied?"

An application for direct appellate review was allowed by this court. We conclude that under certain specified conditions the Probate Court, as a court of general equity jurisdiction, does have the authority to entertain and act upon such a petition.

The facts as they appear in the record are as follows. [Note 1] The ward is a mentally retarded woman born on August 6, 1956. Her emotional, intellectual, and developmental age, however, does not conform to her chronological age, and she currently functions at the level of a four year old. In the view of professionals in the health care field it would be in the best interest of the ward to have an abdominal tubal ligation. Medical practitioners in the Commonwealth refuse to perform the abdominal tubal ligation procedure without a court order. [Note 2]

This case is yet another in an ever-increasing number of cases in recent years where we are requested to apply legal principles to issues involving fundamental personal liberties, requiring the process of "detached but passionate investigation and decision that forms the ideal on which the judicial branch of government was created." Superintendent of Belchertown State School v. Saikewicz, 373 Mass. 728, 759 (1977). See, e.g., Matter of Spring, 380 Mass. 629 (1980); Custody of a Minor (No. 3), 378 Mass. 732 (1979). We proceed to answer the questions posed because we are mindful that this court "cannot escape the demands of judging or of making . . . difficult appraisals." Haynes v. Washington, 373 U.S. 503, 515 (1973). In this case the ward's presumed inability to give her knowing consent regarding a sterilization operation, [Note 3] as a competent individual could, is said to require the aid of the court. [Note 4] The guardian argues that the method to ensure that the ward's best interests are thoroughly protected is judicial intervention.

There is no specific Massachusetts statute granting a guardian the power to authorize a sterilization operation on behalf of his or her ward. General Laws c. 201, Section 6A, as amended through St. 1978, c. 478, Section 95, provides that "[t]he guardian of a mentally retarded person shall act to

Page 559

protect the welfare of such person and may utilize the services of agencies and individuals to provide necessary and desirable social and protective services of different types appropriate to such person including, but not limited to, counseling services, advocacy services, legal services, and other aid as he deems to be in the interest of such person."

Although G. L. c. 201, Section 12, confers the "care and custody" of a ward upon a duly appointed guardian, G. L. c. 112, Section 12W, requires the knowledgeable consent of the individual to be sterilized. In addition, our prior cases have established that prior judicial approval is required before a guardian may consent to administering or withholding of proposed extraordinary medical treatment. E.g., Guardianship of Roe, 383 Mass. 415 (1981); Matter of Spring, supra; Superintendent of Belchertown State School v. Saikewicz, supra. Since sterilization is an extraordinary and highly intrusive from of medical treatment that irreversibly extinguishes the ward's fundamental right of procreative choice, we conclude that a guardian must obtain a proper judicial order for the procedure before he or she can validly consent to it. Guardians and parents, therefore, absent statutory or judicial authorization, cannot consent to the sterilization of a ward in their care or custody.

We are well aware of the sordid history of compulsory eugenic sterilization laws in the United States. See Matter of Grady, 85 N.J. 235, 245-247 (1981). In a constitutional attack on the substance of a State sterilization statute, the United States Supreme Court accepted the basic premises of the eugenic theory that persons with certain diseases or antisocial characteristics (1) tend to procreate more often; (2) have offspring who inherit the parental defect; and (3) do not view sterilization as detrimental. See Buck v. Bell, 274 U.S. 200, 207 (1927); Ferster, Eliminating the Unfit -- Is Sterilization the Answer?, 27 Ohio St. L.J. 591, 602 (1966). Thus, it was thought that sterilization of the unfit would promote the general health and welfare of our society. Id. All the underlying premises of eugenic sterilization, however, have been vigorously criticized and, for the most part,

Page 560

have proven false. See Matter of A.W., Colo., (1981) (637 P.2d 366, 368 [Colo. 1981]); Ferster, supra at 602-604; Kindregan, Sixty Years of Compulsory Eugenic Sterilization: "Three Generations of Imbeciles" and the Constitution of the United States, 43 Chi.-Kent L. Rev. 123, 134-140 (1966). See also Skinner v. Oklahoma, 316 U.S. 535, 546 (1942) (Jackson, J., concurring) (because present state of scientific knowledge uncertain, eugenic sterilization presents grave constitutional questions). Two recent cases show, however, that sterilization procedures may still be abused, see Stump v. Sparkman, 435 U.S. 349 (1978); Downs v. Sawtelle, 574 F.2d 1 (1st Cir.), cert. denied, 439 U.S. 910 (1978).

Massachusetts has never had compulsory sterilization laws. General Laws c. 112, Section 12W, forbids sterilization of any person absent his knowledgeable consent. Nothing we say today condones or approves compulsory sterilization for any purpose. Indeed, we question the continuing validity of the Buck decision, at least as a matter of State law. The right to procreate is "fundamental to the very existence and survival of the race." Skinner, supra at 541. An individual is forever deprived of this basic liberty through unwanted sterilization. Id. The State has no recognizable interest in compelling the sterilization of its citizens. See, e.g., Matter of A.W., supra at (supra at 368) ("compulsory sterilization of incompetents based on eugenic theories can no longer be justified as a valid exercise of governmental authority"). But see Sterilization of Moore, 289 N.C. 95 (1976); Cook v. State, 9 Or. App. 224 (1972).

No compulsory sterilization or sterilization based on discredited eugenic theories is involved here, however. The issues presented seem to us to involve whether an incompetent person is to be given the same rights as those vested in a competent person, and, if so, how and by what means. We turn to consider the questions reported:

1. Power of the Probate Court. Many courts have concluded that, without legislative authorization, a judge lacks the power to order sterilization of an incompetent at the

Page 561

behest of a parent or guardian. Hudson v. Hudson, 373 So.2d 310 (Ala. 1979). Guardianship of Kemp, 43 Cal. App. 3d 758 (1974). In re S.C.E., 378 A.2d 144 (Del. Ch. 1977). A.L. v. G.R.H., 163 Ind. App. 636 (1975), cert. denied, 425 U.S. 936 (1976). In Interest of M.K.R., 515 S.W.2d 467 (Mo. 1974). Frazier v. Levi, 440 S.W.2d 393 (Tex. Civ. App. 1969). Holmes v. Powers, 439 S.W.2d 579 (Ky. App. 1968). Cf. Wade v. Bethesda Hosp., 337 F. Supp. 671 (S.D. Ohio 1971). These cases are distinguishable in some instances, and are generally unpersuasive.

In Guardianship of Kemp, supra, for example, the California court noted that its Probate Court was a court of limited jurisdiction, possessed of no general equity jurisdiction. 43 Cal. App. 3d at 761-762. Compare Matter of D.D., a Mentally Retarded Person, 64 App. Div. 2d 898 (N.Y 1978) (Surrogate's Court, court of limited jurisdiction, has no jurisdiction to order sterilization absent statutory authorization), with Matter of Sallmaier, 85 Misc. 2d 295 (N.Y. Sup. Ct. 1976) (Supreme Court has jurisdiction to order sterilization by virtue of common law parens patriae power over incompetents). Our Probate Court, however, are courts of superior and general jurisdiction possessing inherent powers apart from statutory authorization. These powers are broad and flexible, and extend to actions necessary to afford any relief in the best interests of a person under their jurisdiction. G. L. c. 215, Sections 2, 3, 6. Saikewicz, supra at 755-756. See Guardianship of Bassett, 7 Mass. App. Ct. 56, 61-62 (1979) (Probate Court has traditional equitable power to resolve problems involving mentally retarded persons). G. L. c. 201, Section 6A (Probate Court proper forum to seek appointment of guardian for mentally retarded person). Cf. Police Comm'r of Boston v. Municipal Court of the Dorchester Dist., 374 Mass. 640, 660-665 (1978); G. L. c. 215, Section 6.

In Frazier v. Levi, supra, the Texas court in a cursory opinion, quoting extensively from Corpus Juris Secundum and American Jurisprudence, concluded without stating a reason that "[a]ny order authorizing . . . [sterilization]

Page 562

would be in excess of the power delegated by the statutes of Texas and would be invalid." 440 S.W.2d at 395. As a final example in this line of cases, we not Holmes v. Powers, supra, a two-paragraph opinion, wherein the Kentucky court denied the county health officer and local medical society's petition to sterilize the defendant. 439 S.W.2d at 580. The court stated that "[i]t may be (though we do not decide) that a legally constituted committee could exercise such a choice, but there has been no inquest and there is no committee." Id. We agree with the view taken of these authorities by the Supreme Court of Washington: "These cases are not controlling. Their results are conclusory, as none of them demonstrates any controlling legal principle prohibiting a court of general jurisdiction from acting upon a petition for sterilization. They suggest a preference that the difficult decisions regarding sterilization be made by a legislative body. This is not simply a denial of jurisdiction, but an abdication of the judicial function." Guardianship of Hayes, 93 Wash. 2d 228, 231 (1980).

We find more persuasive the view expressed in most recent decisions that a court of general jurisdiction which has powers of equity over incompetents and their guardians, such as the Probate Court, has the power to hear and adjudicate petitions such as the one in the case at bar. [Note 5] See C.D.M. v. State, 627 P.2d 607 (Alas. 1981); Matter of A.W., supra; Matter of Grady, supra; Matter of Sallmaier, supra; Guardianship of Hayes, supra. See also Guardianship of Eberhardy, 102 Wis. 2d 539 (1981) (Probate Court has jurisdiction to entertain sterilization petition, but public policy and judicial restraint dictate that jurisdiction not be exercised). These decisions recognize that incompetent persons need some forum in which to exercise their statutory and constitutional rights, the same as competent persons. "In our view [the] decisions [denying jurisdiction] do not reflect

Page 563

adequate sensitivity to the constitutional rights of the incompetent person."Matter of Grady, supra at 261.

The Probate Courts in this Commonwealth have general equitable power to act in all matters relating to guardianship. See G. L. c. 215, Section 6. The power to appoint a guardian for a retarded person is confirmed by G. L. c. 201, Sections 6A, 14. This grant of jurisdiction is plenary, Guardianship of Bassett, supra at 63, and is inherent in the court even apart from statutory authorization. Saikewicz supra at 755. The exercise of this power at times becomes necessary for the proper functioning of the court. Buckingham v. Alden, 315 Mass. 383, 389 (1944).

In Saikewicz, this court stated that "[i]n dealing with matters concerning a person properly under the court's protective jurisdiction, `[t]he court's action . . . is not limited by any narrow bounds, but it is empowered to stretch forth its arm in whatever direction its aid and protection may be needed'. . . . In essence the powers of the court to act in the best interests of a person under its jurisdiction . . . must be broad and flexible enough `to afford whatever relief may be necessary to protect his interests.'. . . The Probate Court is the proper forum in which to determine the need for the appointment of a guardian or a guardian ad litem. It is also the proper tribunal to determine the best interests of a ward." (citations omitted). Saikewicz, supra at 755-756.

In the absence of any limiting legislative enactment, the Probate Court has plenary power to exercise its jurisdiction to provide for the needs of the mentally incompetent person. Cf. Matter of A.W., supra at (supra at 375).

2. The right to choose sterilization. The Supreme Court of the United States has implicitly recognized that the right of a person to be sterilized is a fundamental right. Skinner v. Oklahoma, 316 U.S. 535, 541 (1942). Other courts have explicitly recognized such a right. See Hathaway v. Worcester City Hosp., 475 F.2d 701 (1st Cir. 1973); Ruby v. Massey, 452 F. Supp. 361, 368 (D. Conn. 1978). Cf. Relf v. Weinberger, 372 F. Supp. 1196 (D.D.C. 1974). The right

Page 564

to reproduce and the decision whether or not to beget or bear a child is at the very heart of the constitutionally protected right to privacy. See Carey v. Population Servs. Int'l, 431 U.S. 678, 685-686 (1977) (plurality); Skinner, supra. "If the right of privacy means anything it is the right of the individual, married or single, to be free from unwarranted governmental intrusion into matters so fundamentally affecting a person as the decision whether to bear or beget a child." Eisenstadt v. Baird, 405 U.S. 438, 453 (1972). See Griswold v. Connecticut, 381 U.S. 479, 485 (1965) (several fundamental constitutional guaranties create zone of privacy around procreation decisions). See generally L. Tribe, American Constitutional Law 921-934, Section 15-10 (1978). "The constitutional right to privacy,. . . is an expression of the sanctity of individual free choice and self-determination as fundamental constituents of life." Saikewicz, supra at 742. This right of human dignity extends to all individual of his or her right to privacy if it denies the person the opportunity to exercise that right. See Matter of A.W., supra at (supra at 369) (individual has fundamental right not to be source of another life; right includes freedom to make choice permanent by voluntarily undergoing sterilization); Guardianship of Eberhardy, supra at 907 (Day, J., dissenting) (judicial refusal to consent to sterilization on petition of parent or guardian effectively makes fundamental personal choice for ward).

We have, in the past, consistently respected the right of a person to be free from nonconsensual invasion of bodily integrity. See, e.g., Guardianship of Roe, 383 Mass. at 434; Matter of Spring, 380 Mass. at 634. Cf. Commissioner of Correction v. Myers, 379 Mass. 255 (1979).

Although G. L. c. 112, Section 12W, which prohibits a physician from performing a sterilization unless the physician has the knowledgeable consent of the patient in writing, appears to be "limiting" legislation, this statute cannot be read to deny incompetent individuals the same procreative choices

Page 565

which competent persons may exercise. See also G. L. c. 111, Section 70E. Because a competent individual has a right to be sterilized, see infra, "[t]o deny this right to persons who are incapable of exercising it personally is to degrade those whose disabilities make them wholly reliant on other, more fortunate, individuals." Guardianship of Roe, supra at 434. "To protect the incompetent person within its power, the State must recognize the dignity and worth of such a person and afford to that person the same panoply of rights and choices it recognizes in competent persons." Saikewicz, supra at 746. This is accomplished through the doctrine of substituted judgment determined by proceedings in a court of competent jurisdiction. See Guardianship of Roe, supra at 444; Matter of Spring, supra at 634; Saikewicz, supra at 751-752. We conclude that the answer to the first question reported is, "Yes."

3. Procedure. (a) Substituted judgment. In utilizing the doctrine of substituted judgment, this court seeks to maintain the integrity of the incompetent person by giving the individual a forum in which his or her rights may be exercised. The court dons "the mental mantle of the incompetent" and substitutes itself as nearly as possible for the individual in the decision-making process. Saikewicz, supra at 752, quoting from In re Carson, 39 Misc. 2d 544, 545 (N.Y. Sup. Ct. 1962). In utilizing the doctrine the court does not decide what is necessarily the best decision but rather what decision would be made by the incompetent person if he or she were competent. "In short, if an individual would, if competent, make an unwise or foolish decision, the judge must respect that decision as long as he would accept [or be bound to accept] the same decision if made by a competent individual in the same circumstances." Guardianship of Roe, supra at 449 n.20. Compare Custody of a Minor (No. 3), 378 Mass. 732, 744 (1979) (parental rights do not clothe parent with life and death authority over children).

We are aware of the difficulties of utilizing the substituted judgment doctrine in a case where the incompetent

Page 566

has been mentally retarded since birth. The inability, however, of an incompetent to choose, should not result in a loss of the person's constitutional interests. Matter of A.W., supra at (supra at 375). To speak solely in terms of the "best interests" of the ward, or of the State's interest, is to obscure the fundamental issue: Is the State to impose a solution on an incompetent based on external criteria, or is it to seek to protect and implement the individual's personal rights and integrity? We reject the former possibility. Each approach has its own difficulties, but the use of the doctrine of substituted judgment promotes best the interests of the individual, no matter how difficult the task involved may be. We admit that in this case we are unable to draw upon prior stated preferences the individual may have expressed. An expression of intent by an incompetent person while competent, however, is not essential. Matter of Spring, supra at 640. "While it may thus be necessary to rely to a greater degree on objective criteria . . . the effort to bring the substituted judgment into step with the values and desires of the affected individual must not, and need not, be abandoned." Saikewicz, supra at 751. Cf. Matter of Storar, 52 N.Y.2d 363, 380 (1981) (unrealistic to attempt substituted judgment where person incompetent since birth). The courts thus must endeavor, as accurately as possible, to determine the wants and needs of this ward as they relate to the sterilization procedure. See Saikewicz, supra at 750 n.15.

b. Applicable standards. We now consider the standards the Probate Court must apply when authorizing sterilization upon petition of an incompetent person's parent or guardian. We keep in mind that the court is to determine whether to authorize sterilization when requested by the parents or guardian by finding the incompetent would so choose if competent. No sterilization is to be compelled on the basis of any State or parental interest.

In all cases, the parties must be given adequate notice of the proceedings, an opportunity to be heard in the trial court, and to pursue an appeal. Upon a guardian's petition

Page 567

for an order authorizing the sterilization of his or her ward, the court must appoint a guardian ad litem to represent the ward. [Note 6] The guardian ad litem is to be charged with the responsibility of zealously representing the ward, and must have full opportunity to meet with the ward, present proof, and cross-examine witnesses at the hearing. Matter of Grady, supra at 264. In order to guarantee a thorough adversary exploration of the difficult question posed, the guardian ad litem should present all reasonable arguments in favor of the court's denial of the petition, so that "all viewpoints and alternatives will be aggressively pursued and examined at the subsequent hearing." Saikewicz, supra at 757. This adversary posture will ensure that both sides of each issue which the court must consider are thoroughly aired before findings are made and a decision rendered. Accord C.D.M. v. State, supra at 612; Matter of A.W., supra at (supra at 375); Matter of Grady, supra at 264; Guardianship of Hayes, supra at 236-238.

In addition to the appointment of a guardian ad litem, the court may appoint independent medical and psychological experts for the purpose of examining the ward and reporting to the court. See Matter of A.W., supra. The experts should report, and the court make, findings regarding: (1) Whether the ward, despite being mentally retarded, is able to make an informed choice as to the need and desirability of sterilization. Thus, as a threshold matter, the court, on the basis of the experts' reports and evidence adduced at the hearing, must determine whether the individual lacks the capacity to make his or her own decision concerning sterilization and whether this condition is likely to change in the near future. [Note 7] A person may be adjudicated legally incompetent

Page 568

to make some decisions but competent to make other decisions. Guardianship of Bassett, 7 Mass. App. Ct. 56, 63 (1979). See also Lane v. Candura, 6 Mass. App. Ct. 377 (1978). Therefore, although the ward in this case has been adjudicated "incapable of making informed decisions with respect to the conduct of [her] personal and financial affairs," G. L. c. 201, Section 6A, this is not dispositive on the issues of her competency to make a decision regarding sterilization. [Note 8] (2) The physical ability of the ward to procreate.

Page 569

Where, however, the ward has reached sexual maturity, the court may presume fertility, absent medical evidence to the contrary. [Note 9] (3) The possibility and effectiveness of less intrusive means of birth control. The court should find that all less drastic contraceptive methods, including supervision, education, and training are unworkable. Matter of A.W., supra at n.21 (supra at 376 n.21). C.D.M. v. State, supra at 613. Guardianship of Hayes, supra at 238-239. The court should also find that the proposed method of sterilization entails, the least intrusive invasion of the ward's body. Relevant to this inquiry is whether a reversible sterilization procedure or less drastic contraception method will soon be available. Guardianship of Hayes, supra at 239. (4) The medical necessity, if any, for the procedure. [Note 10] A medical necessity could be supported by evidence that the possibility of pregnancy would threaten the physical or mental health of the person. Matter of A.W., supra at (supra at 375). (5) The nature and extent of the individual's disability. This inquiry should focus on the ability of the ward to care for a child, even with reasonable assistance, and the possibility that the ward may marry in the future and, with a spouse, be able to care for a child. Matter of Grady, supra at 266. Guardianship of Hayes, supra at 238. In examining whether the ward would likely be able to care

Page 570

for a child, the court should consider whether science is on the threshold of an advance in the treatment of the ward's disability. Guardianship of Hayes, supra at 239. (6) The likelihood that the ward will engage in sexual activity likely to result in pregnancy. (7) The possibility of health risks, trauma, or psychological damage from the sterilization operation, as well as pregnancy or childbirth.

The court, to the extent possible, must also "elicit testimony from the incompetent concerning [his or] her understanding and desire for the proposed operation and its consequences." C.D.M. v. State, supra at 613. The judge, in his discretion, and the guardian ad litem in his recommendation, should attempt to ascertain the ward's actual preference for sterilization, parenthood, or other means of contraception. This inquiry is an important part of the substituted judgment determination. The result of the judge's exercise of discretion should be the same decision which would be made by the incompetent person, "but taking into account the present and future incompetency of the individual as one of the factors which would necessarily enter into the decision-making process of the competent person." Saikewicz, supra at 752-753.

Additionally, the court must consider the ward's religious beliefs, if any. Guardianship of Roe, supra at 445. An individual might choose to refuse sterilization if the operation would be contrary to his or her religious beliefs. "If such a reason is proffered by or on behalf of an incompetent, the judge must evaluate it in the same manner and for the same purposes as any other reason: the question to be addressed is whether certain tenets or practices of the incompetent's faith would cause him [or her] in [the] present circumstances." Id. The Probate Court judge should also consider any special circumstances presented by the parties in favor of, or against, the proposed sterilization.

c. Standard of Proof. We emphasize again that this is not a case wherein the Commonwealth seeks to interfere with the ward's fundamental right to procreate. If that

Page 571

were the case, arguably, the Commonwealth would be required to show a compelling State interest for the sterilization and the standard of proof could be higher than the usual civil standard of preponderance of the evidence. [Note 11] See, e.g., Addington v. Texas, 441 U.S. 418 (1979) (due process requires State standard of proof greater than preponderance of evidence in civil commitment proceedings). Cf. In re Penny N., 120 N.H. 269, 271-272 (1980) (proof beyond reasonable doubt rejected as standard; New Hampshire court adopts requirement of "clear and convincing evidence" as the "middle course"). We reject, however, the argument that any legitimate State interest exists which would warrant a decision to require involuntary sterilization. Cf. Relf v. Weinberger, 372 F. Supp. 1196, 1201 (D.D.C. 1974). Consequently, we reject the view that proof beyond a reasonable doubt is required to justify a sterilization authorization. But see North Carolina Ass'n for Retarded Children v. State, 420 F. Supp. 451 (M.D.N.C. 1976); In re Simpson, 180 N.E.2d 206 (Ohio Prob. 1962).

This is a case where a mother, as guardian of her daughter, is asking the court to utilize the doctrine of substituted judgment and consent to a sterilization operation that the guardian feels would be in the ward's best interest. [Note 12] We have already stated that the incompetent individual has as much right as the competent individual to assert his or her constitutional right to privacy.

In Guardianship of Roe, this court held that the Commonwealth had to prove its interest in the prevention of

Page 572

violence, beyond a reasonable doubt, in order to "overrid[e] the individual's right to refuse" antipsychotic drugs. 383 Mass. at 450. There, "[t]he primary purpose of the treatment [was] not to implement the substituted judgment of the incompetent." Id. In this case there is no State interest which could override the ward's refusal, or the court's substituted judgment of refusal, consent to sterilization. The higher standard of proof is invoked when the State seeks to interfere with a person's liberty, not when the individual seeks to exercise his or her liberty.

Further, we think that to require a high standard of proof in such a proceeding, that recognizes and implements the incompetent's rights, would defeat the entire purpose of the proceeding and have the effect of denying recognition of rights for incompetents that are available to people who are competent. For example, that science is on the threshold of cure for the ward's disability is a nebulous eventuality of science that is impossible to prove beyond a reasonable doubt. A requirement of proof beyond a reasonable doubt of such a possibility would jeopardize an incompetent's fundamental right to decide whether to bear or beget a child and, might well preclude it. Cf. Custody of a Minor (No. 1), 377 Mass. 876, 885 (1979).

We prefer to take the position that the personal rights implicated in guardian or parent petitions for sterilization require the judge to exercise the utmost care in reviewing all the evidence presented and in determining whether the ward would consent to sterilization if competent to make such a decision. Id. at 885-886. The judge must enter detailed written findings indicating those persuasive factors that determine the outcome. We are persuaded that a conscientious judge, being mindful of adverse mental and social consequence which might follow the authorization or not of a sterilization operation, will give serious and heedful attention at all stages of the proceeding.

Report discharged.

Page 573

NOLAN, J. (dissenting). I dissent. Sterilization is a species of self mutilation which is almost always irreversible. Its effect is to deprive the sterilized person of her or his capacity to beget or bear a child. We do not deal here with what has been described as therapeutic sterilization in which as a secondary effect to an operative procedure which is necessary to save the life of a person such person is rendered sterile (e.g., cancer of a reproductive organ may require its surgical removal).

The court today has decided that the probate judge has the power to divine the wishes of a severely mentally retarded women who "currently functions at the level of a four year old" as to whether she should permit herself to be rendered forever incapable of conceiving and bearing a child. To say the least, this is an impossible task.

An examination of the criteria which are prescribed for the probate judge's consideration leads me to the conclusion that the bias is heavily in favor of contraception. Somehow, pregnancy comes off as an evil to be avoided. The court vouchsafes that the probate judge must consider the possibility of "less intrusive means of birth control." The opinion continues: "The court should find that all less drastic contraceptive methods, including supervision, education, and training are unworkable."

The court seems to find support for its position in the fact that competent men and women have a statutory right to be sterilized according to G. L. c. 112, Section 12W, and that (the argument continues) the government deprives the incompetent person of a sacred constitutional right to be sterilized if it denies a judge the power to approve such sterilization. The flaw in this argument is its attribution of denial of such a dubious right to the government. It is the incompetent's mental condition which makes him or her incapable of free choice, not the government. The very condition of incompetence makes the doctrine of substituted judgment a cruel charade.

The court speaks of human dignity in connection with the free choice to be sterilized. It is difficult to think of an experience

more degrading to human dignity than a sterilization ordered by a judge who is empowered by the court to read the heart and mind of the incompetent ward and forever bar the ward from bringing forth a child.
