Liberty finds no refuge in a jurisprudence of doubt. Yet, 19 years after our holding that the Constitution protects a woman's right to terminate her pregnancy in its early stages, Roe v. Wade, 410 U.S. 113 (1973), that definition of liberty is still questioned. Joining the respondents as amicus curiae, the United States, as it has done in five other cases in the last decade, again asks us to overrule Roe. . . .
After considering the fundamental constitutional questions resolved by Roe, principles of institutional integrity, and the rule of stare decisis, we are led to conclude this: the essential holding of Roe v. Wade should be retained and once again reaffirmed.
It must be stated at the outset and with clarity that Roe's essential holding, the holding we reaffirm, has three parts.
First is a recognition of the right of the woman to choose to have an abortion before viability and to obtain it without undue interference from the State. Before viability, the State's interests are not strong enough to support a prohibition of abortion or the imposition of a substantial obstacle to the woman's effective right to elect the procedure.
Second is a confirmation of the State's power to restrict abortions after fetal viability if the law contains exceptions for pregnancies which endanger the woman's life or health.
And third is the principle that the State has legitimate interests from the outset of the pregnancy in protecting the health of the woman and the life of the fetus that may become a child. These principles do not contradict one another; and we adhere to each.
II.
Constitutional protection of the woman's decision to terminate her pregnancy derives from the Due Process Clause of the Fourteenth Amendment. It declares that no State shall "deprive any person of life, liberty, or property, without due process of law." The controlling word in the cases before us is "liberty."
. . . [T]he full scope of the liberty guaranteed by the Due Process Clause cannot be found in or limited by the precise terms of the specific guarantees elsewhere provided in the Constitution. This "liberty" is not a series of isolated points pricked out in terms of the taking of property; the freedom of speech, press, and religion; the right to keep and bear arms; the freedom from unreasonable searches and seizures; and so on. It is a rational continuum which, broadly speaking, includes a freedom from all substantial arbitrary impositions and purposeless restraints, . . . and which also recognizes, what a reasonable and sensitive judgment must, that certain interests require particularly careful scrutiny of the state needs asserted to justify their abridgment. . . .
. . . It is settled now, as it was when the Court heard arguments in Roe v. Wade, that the Constitution places limits on a State's right to interfere with a person's most basic decisions about family and parenthood. . . .
. . . Men and women of good conscience can disagree, and we suppose some always shall disagree, about the profound moral and spiritual implications of terminating a pregnancy, even in its earliest stage. Some of us as individuals find abortion offensive to our most basic principles of morality, but that cannot control our decision. Our obligation is to define the liberty of all, not to mandate our own moral code. The underlying constitutional issue is whether the State can resolve these philosophic questions in such a definitive way that a woman lacks all choice in the matter, except perhaps in those rare circumstances in which the pregnancy is itself a danger to her own life or health, or is the result of rape or incest. . . .
. . . It is conventional constitutional doctrine that, where reasonable people disagree, the government can adopt one position or the other That theorem, however, assumes a state of affairs in which the choice does not intrude upon a protected liberty. Thus, while some people might disagree about whether or not the flag should be saluted, or disagree about the proposition that it may not be defiled, we have ruled that [size=28]a State may not compel or enforce one view or the other[/size]. . . .
Our law affords constitutional protection to personal decisions relating to marriage, procreation, contraception, family relationships, child rearing, and education. Our cases recognize 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. Our precedents "have respected the private realm of family life which the state cannot enter." These matters, involving the most intimate and personal choices a person may make in a lifetime, choices central to personal dignity and autonomy, are central to the liberty protected by the Fourteenth Amendment. At the heart of liberty is the right to define one's own concept of existence, of meaning, of the universe, and of the mystery of human life. Beliefs about these matters could not define the attributes of personhood were they formed under compulsion of the State. . . .
. . . Though abortion is conduct, it does not follow that the State is entitled to proscribe it in all instances. That is because the liberty of the woman is at stake in a sense unique to the human condition, and so, unique to the law. The mother who carries a child to full term is subject to anxieties, to physical constraints, to pain that only she must bear. That these sacrifices have from the beginning of the human race been endured by woman with a pride that ennobles her in the eyes of others and gives to the infant a bond of love cannot alone be grounds for the State to insist she make the sacrifice. Her suffering is too intimate and personal for the State to insist, without more, upon its own vision of the woman's role, however dominant that vision has been in the course of our history and our culture. The destiny of the woman must be shaped to a large extent on her own conception of her spiritual imperatives and her place in society. . . .
. . . for two decades of economic and social developments, people have organized intimate relationships and made choices that define their views of themselves and their places in society, in reliance on the availability of abortion in the event that contraception should fail. The ability of women to participate equally in the economic and social life of the Nation has been facilitated by their ability to control their reproductive lives. The Constitution serves human values, and while the effect of reliance on Roe cannot be exactly measured, neither can the certain cost of overruling Roe for people who have ordered their thinking and living around that case be dismissed. . . .
. . . The soundness of this prong of the Roe analysis is apparent from a consideration of the alternative. If indeed the woman's interest in deciding whether to bear and beget a child had not been recognized as in Roe, the State might as readily restrict a woman's right to choose to carry a pregnancy to term as to terminate it, to further asserted state interests in population control, or eugenics, for example. Yet Roe has been sensibly relied upon to counter any such suggestions. . . .
IV
From what we have said so far, it follows that it is a constitutional liberty of the woman to have some freedom to terminate her pregnancy. We conclude that the basic decision in Roe was based on a constitutional analysis which we cannot now repudiate. The woman's liberty is not so unlimited, however, that, from the outset, the State cannot show its concern for the life of the unborn and, at a later point in fetal development, the State's interest in life has sufficient force so that the right of the woman to terminate the pregnancy can be restricted.
That brings us, of course, to the point where much criticism has been directed at Roe, a criticism that always inheres when the Court draws a specific rule from what in the Constitution is but a general standard. We conclude, however, that the urgent claims of the woman to retain the ultimate control over her destiny and her body, claims implicit in the meaning of liberty, require us to perform that function. Liberty must not be extinguished for want of a line that is clear. And it falls to us to give some real substance to the woman's liberty to determine whether to carry her pregnancy to full term. . . .
The woman's right to terminate her pregnancy before viability is the most central principle of Roe v. Wade. It is a rule of law and a component of liberty we cannot renounce.
. . . A finding of an undue burden is a shorthand for the conclusion that a state regulation has the purpose or effect of placing a substantial obstacle in the path of a woman seeking an abortion of a nonviable fetus. A statute with this purpose is invalid because the means chosen by the State to further the interest in potential life must be calculated to inform the woman's free choice, not hinder it. And a statute which, while furthering the interest in potential life or some other valid state interest, has the effect of placing a substantial obstacle in the path of a woman's choice cannot be considered a permissible means of serving its legitimate ends. . . .

Section 3209 of Pennsylvania's abortion law provides, except in cases of medical emergency, that no physician shall perform an abortion on a married woman without receiving a signed statement from the woman that she has notified her spouse that she is about to undergo an abortion. The woman has the option of providing an alternative signed statement certifying that her husband is not the man who impregnated her; that her husband could not be located; that the pregnancy is the result of spousal sexual assault which she has reported; or that the woman believes that notifying her husband will cause him or someone else to inflict bodily injury upon her. A physician who performs an abortion on a married woman without receiving the appropriate signed statement will have his or her license revoked, and is liable to the husband for damages. . . .
We recognize that a husband has a deep and proper concern and interest . . . in his wife's pregnancy and in the growth and development of the fetus she is carrying. With regard to the children he has fathered and raised, the Court has recognized his "cognizable and substantial" interest in their custody. If this case concerned a State's ability to require the mother to notify the father before taking some action with respect to a living child raised by both, therefore, it would be reasonable to conclude, as a general matter, that the father's interest in the welfare of the child and the mother's interest are equal.
Before birth, however, the issue takes on a very different cast. It is an inescapable biological fact that state regulation with respect to the child a woman is carrying will have a far greater impact on the mother's liberty than on the father's. The effect of state regulation on a woman's protected liberty is doubly deserving of scrutiny in such a case, as the State has touched not only upon the private sphere of the family, but upon the very bodily integrity of the pregnant woman.
The Court has held that, when the wife and the husband disagree on this decision, the view of only one of the two marriage partners can prevail. Inasmuch as it is the woman who physically bears the child and who is the more directly and immediately affected by the pregnancy, as between the two, the balance weighs in her favor. This conclusion rests upon the basic nature of marriage and the nature of our Constitution: [T]he marital couple is not an independent entity with a mind and heart of its own, but an association of two individuals, each with a separate intellectual and emotional makeup. 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. The Constitution protects individuals, men and women alike, from unjustified state interference, even when that interference is enacted into law for the benefit of their spouses.
There was a time, not so long ago, when a different understanding of the family and of the Constitution prevailed. In Bradwell v. State, 16 Wall. 130 (1873), three Members of this [505 U.S. 833, 897] Court reaffirmed the common law principle that a woman had no legal existence separate from her husband, who was regarded as her head and representative in the social state; and, notwithstanding some recent modifications of this civil status, many of the special rules of law flowing from and dependent upon this cardinal principle still exist in full force in most States. Id., at 141 (Bradley, J., joined by Swayne and Field, JJ., concurring in judgment). Only one generation has passed since this Court observed that "woman is still regarded as the center of home and family life," with attendant "special responsibilities" that precluded full and independent legal status under the Constitution. Hoyt v. Florida, 368 U.S. 57, 62 (1961). These views, of course, are no longer consistent with our understanding of the family, the individual, or the Constitution.
In keeping with our rejection of the common law understanding of a woman's role within the family, the Court held in Danforth that the Constitution does not permit a State to require a married woman to obtain her husband's consent before undergoing an abortion. 428 U.S., at 69 . The principles that guided the Court in Danforth should be our guides today. For the great many women who are victims of abuse inflicted by their husbands, or whose children are the victims of such abuse, a spousal notice requirement enables the husband to wield an effective veto over his wife's decision. Whether the prospect of notification itself deters such women from seeking abortions, or whether the husband, through physical force or psychological pressure or economic coercion, prevents his wife from obtaining an abortion until it is too late, the notice requirement will often be tantamount to the veto found unconstitutional in Danforth. The women most affected by this law - those who most reasonably fear the consequences of notifying their husbands that they are pregnant - are in the gravest danger. [505 U.S. 833, 898]
The husband's interest in the life of the child his wife is carrying does not permit the State to empower him with this troubling degree of authority over his wife. The contrary view leads to consequences reminiscent of the common law. A husband has no enforceable right to require a wife to advise him before she exercises her personal choices. If a husband's interest in the potential life of the child outweighs a wife's liberty, the State could require a married woman to notify her husband before she uses a post-fertilization contraceptive. Perhaps next in line would be a statute requiring pregnant married women to notify their husbands before engaging in conduct causing risks to the fetus. After all, if the husband's interest in the fetus' safety is a sufficient predicate for state regulation, the State could reasonably conclude that pregnant wives should notify their husbands before drinking alcohol or smoking. Perhaps married women should notify their husbands before using contraceptives or before undergoing any type of surgery that may have complications affecting the husband's interest in his wife's reproductive organs. And if a husband's interest justifies notice in any of these cases, one might reasonably argue that it justifies exactly what the Danforth Court held it did not justify - a requirement of the husband's consent as well. A State may not give to a man the kind of dominion over his wife that parents exercise over their children.
Section 3209 embodies a view of marriage consonant with the common law status of married women, but repugnant to our present understanding of marriage and of the nature of the rights secured by the Constitution. Women do not lose their constitutionally protected liberty when they marry. The Constitution protects all individuals, male or female, married or unmarried, from the abuse of governmental power, even where that power is employed for the supposed benefit of a member of the individual's family. These considerations confirm our conclusion that 3209 is invalid. [505 U.S. 833, 899]
