Justice KENNEDY delivered the opinion of the Court.
Liberty protects the person from unwarranted government intrusions into a dwelling or other private places. In our tradition the State is not omnipresent in the home. And there are other spheres of our lives and existence, outside the home, where the State should not be a dominant presence. Freedom extends beyond spatial bounds. Liberty presumes an autonomy of self that includes freedom of thought, belief, expression, and certain intimate conduct. The instant case involves liberty of the person both in its spatial and more transcendent dimensions. . . .
In Houston, Texas, officers of the Harris County Police Department were dispatched to a private residence in response to a reported weapons disturbance. They entered an apartment where one of the petitioners, John Geddes Lawrence, resided. The right of the police to enter does not seem to have been questioned. The officers observed Lawrence and another man, Tyron Garner, engaging in a sexual act. The two petitioners were arrested, held in custody over night, and charged and convicted before a Justice of the Peace.
The complaints described their crime as "deviate sexual intercourse, namely anal sex, with a member of the same sex (man)." The applicable state law is Tex. Penal Code Ann. §21.06(a) (2003). It provides: "A person commits an offense if he engages in deviate sexual intercourse with another individual of the same sex." The statute defines "[d]eviate sexual intercourse" as follows:
"(A) any contact between any part of the genitals of one person and the mouth or anus of another person; or
"(B) the penetration of the genitals or the anus of another person with an object." §21.01(1). . . .
We conclude the case should be resolved by determining whether the petitioners were free as adults to engage in the private conduct in the exercise of their liberty under the Due Process Clause of the Fourteenth Amendment to the Constitution. For this inquiry we deem it necessary to reconsider the Court's holding in [Bowers v. Hardwick, 478 U. S. 186 (1986)].
There are broad statements of the substantive reach of liberty under the Due Process Clause in earlier cases, including Pierce v. Society of Sisters, and Meyer v. Nebraska; but the most pertinent beginning point is our decision in Griswold v. Connecticut.
In Griswold the Court invalidated a state law prohibiting the use of drugs or devices of contraception and counseling or aiding and abetting the use of contraceptives. The Court described the protected interest as a right to privacy and placed emphasis on the marriage relation and the protected space of the marital bedroom.
After Griswold it was established that the right to make certain decisions regarding sexual conduct extends beyond the marital relationship. In Eisenstadt v. Baird, 405 U. S. 438 (1972), the Court invalidated a law prohibiting the distribution of contraceptives to unmarried persons. . . .
The opinions in Griswold and Eisenstadt were part of the background for the decision in Roe v. Wade. As is well known, the case involved a challenge to the Texas law prohibiting abortions, but the laws of other States were affected as well. Although the Court held the woman's rights were not absolute, her right to elect an abortion did have real and substantial protection as an exercise of her liberty under the Due Process Clause. The Court cited cases that protect spatial freedom and cases that go well beyond it. Roe recognized the right of a woman to make certain fundamental decisions affecting her destiny and confirmed once more that the protection of liberty under the Due Process Clause has a substantive dimension of fundamental significance in defining the rights of the person. . . .
The facts in Bowers had some similarities to the instant case. A police officer, whose right to enter seems not to have been in question, observed Hardwick, in his own bedroom, engaging in intimate sexual conduct with another adult male. The conduct was in violation of a Georgia statute making it a criminal offense to engage in sodomy. One difference between the two cases is that the Georgia statute prohibited the conduct whether or not the participants were of the same sex, while the Texas statute, as we have seen, applies only to participants of the same sex. Hardwick was not prosecuted, but he brought an action in federal court to declare the state statute invalid. He alleged he was a practicing homosexual and that the criminal prohibition violated rights guaranteed to him by the Constitution. The Court, in an opinion by Justice White, sustained the Georgia law. . . .
The Court began its substantive discussion in Bowers as follows: "The issue presented is whether the Federal Constitution confers a fundamental right upon homosexuals to engage in sodomy and hence invalidates the laws of the many States that still make such conduct illegal and have done so for a very long time." That statement, we now conclude, discloses the Court's own failure to appreciate the extent of the liberty at stake. To say that the issue in Bowers was simply the right to engage in certain sexual conduct demeans the claim the individual put forward, just as it would demean a married couple were it to be said marriage is simply about the right to have sexual intercourse. The laws involved in Bowers and here are, to be sure, statutes that purport to do no more than prohibit a particular sexual act. Their penalties and purposes, though, have more far-reaching consequences, touching upon the most private human conduct, sexual behavior, and in the most private of places, the home. The statutes do seek to control a personal relationship that, whether or not entitled to formal recognition in the law, is within the liberty of persons to choose without being punished as criminals.
This, as a general rule, should counsel against attempts by the State, or a court, to define the meaning of the relationship or to set its boundaries absent injury to a person or abuse of an institution the law protects. It suffices for us to acknowledge that adults may choose to enter upon this relationship in the confines of their homes and their own private lives and still retain their dignity as free persons. When sexuality finds overt expression in intimate conduct with another person, the conduct can be but one element in a personal bond that is more enduring. The liberty protected by the Constitution allows homosexual persons the right to make this choice.
Having misapprehended the claim of liberty there presented to it, and thus stating the claim to be whether there is a fundamental right to engage in consensual sodomy, the Bowers Court said: "Proscriptions against that conduct have ancient roots." In academic writings, and in many of the scholarly amicus briefs filed to assist the Court in this case, there are fundamental criticisms of the historical premises relied upon by the majority and concurring opinions in Bowers. . . . It was not until the 1970's that any State singled out same-sex relations for criminal prosecution, and only nine States have done so. . . .
Two principal cases decided after Bowers cast its holding into even more doubt. In Planned Parenthood of Southeastern Pa. v. Casey, 505 U. S. 833 (1992), the Court reaffirmed the substantive force of the liberty protected by the Due Process Clause. The Casey decision again confirmed that our laws and tradition afford constitutional protection to personal decisions relating to marriage, procreation, contraception, family relationships, child rearing, and education. . . .
The second post-Bowers case of principal relevance is Romer v. Evans, 517 U.S. 620 (1996). There the Court struck down class-based legislation directed at homosexuals as a violation of the Equal Protection Clause. Romer invalidated an amendment to Colorado's constitution which named as a solitary class persons who were homosexuals, lesbians, or bisexual either by "orientation, conduct, practices or relationships," and deprived them of protection under state antidiscrimination laws. We concluded that the provision was "born of animosity toward the class of persons affected" and further that it had no rational relation to a legitimate governmental purpose. . . .
Equality of treatment and the due process right to demand respect for conduct protected by the substantive guarantee of liberty are linked in important respects, and a decision on the latter point advances both interests. If protected conduct is made criminal and the law which does so remains unexamined for its substantive validity, its stigma might remain even if it were not enforceable as drawn for equal protection reasons. When homosexual conduct is made criminal by the law of the State, that declaration in and of itself is an invitation to subject homosexual persons to discrimination both in the public and in the private spheres. The central holding of Bowers has been brought in question by this case, and it should be addressed. Its continuance as precedent demeans the lives of homosexual persons. . . .
The doctrine of stare decisis is essential to the respect accorded to the judgments of the Court and to the stability of the law. It is not, however, an inexorable command. In Casey we noted that when a Court is asked to overrule a precedent recognizing a constitutional liberty interest, individual or societal reliance on the existence of that liberty cautions with particular strength against reversing course. The holding in Bowers, however, has not induced detrimental reliance comparable to some instances where recognized individual rights are involved. Indeed, there has been no individual or societal reliance on Bowers of the sort that could counsel against overturning its holding once there are compelling reasons to do so. Bowers itself causes uncertainty, for the precedents before and after its issuance contradict its central holding. . . .
Bowers was not correct when it was decided, and it is not correct today. It ought not to remain binding precedent. Bowers v. Hardwick should be and now is overruled.
The present case does not involve minors. It does not involve persons who might be injured or coerced or who are situated in relationships where consent might not easily be refused. It does not involve public conduct or prostitution. It does not involve whether the government must give formal recognition to any relationship that homosexual persons seek to enter. The case does involve two adults who, with full and mutual consent from each other, engaged in sexual practices common to a homosexual lifestyle. The petitioners are entitled to respect for their private lives. The State cannot demean their existence or control their destiny by making their private sexual conduct a crime. Their right to liberty under the Due Process Clause gives them the full right to engage in their conduct without intervention of the government. "It is a promise of the Constitution that there is a realm of personal liberty which the government may not enter." Casey, supra, at 847. The Texas statute furthers no legitimate state interest which can justify its intrusion into the personal and private life of the individual.
Had those who drew and ratified the Due Process Clauses of the Fifth Amendment or the Fourteenth Amendment known the components of liberty in its manifold possibilities, they might have been more specific. They did not presume to have this insight. They knew times can blind us to certain truths and later generations can see that laws once thought necessary and proper in fact serve only to oppress. As the Constitution endures, persons in every generation can invoke its principles in their own search for greater freedom.
The judgment of the Court of Appeals for the Texas Fourteenth District is reversed, and the case is remanded for further proceedings not inconsistent with this opinion.
Justice O'CONNOR, concurring in the judgment.
The Court today overrules Bowers v. Hardwick, 478 U. S. 186 (1986). I joined Bowers, and do not join the Court in overruling it. Nevertheless, I agree with the Court that Texas' statute banning same-sex sodomy is unconstitutional. Rather than relying on the substantive component of the Fourteenth Amendment's Due Process Clause, as the Court does, I base my conclusion on the Fourteenth Amendment's Equal Protection Clause.
The Equal Protection Clause of the Fourteenth Amendment "is essentially a direction that all persons similarly situated should be treated alike." Cleburne v. Cleburne Living Center, Inc., 473 U. S. 432, 439 (1985); see also Plyler v. Doe, 457 U. S. 202, 216 (1982). Under our rational basis standard of review, "legislation is presumed to be valid and will be sustained if the classification drawn by the statute is rationally related to a legitimate state interest." Cleburne v. Cleburne Living Center, supra, at 440; see also Department of Agriculture v. Moreno, 413 U. S. 528, 534 (1973); Romer v. Evans, 517 U. S. 620, 632-633 (1996); Nordlinger v. Hahn, 505 U. S. 1, 11-12 (1992).
Laws such as economic or tax legislation that are scrutinized under rational basis review normally pass constitutional muster, since "the Constitution presumes that even improvident decisions will eventually be rectified by the democratic processes." Cleburne v. Cleburne Living Center, supra, at 440. . . .
Texas attempts to justify its law, and the effects of the law, by arguing that the statute satisfies rational basis review because it furthers the legitimate governmental interest of the promotion of morality. In Bowers, we held that a state law criminalizing sodomy as applied to homosexual couples did not violate substantive due process. We rejected the argument that no rational basis existed to justify the law, pointing to the government's interest in promoting morality. The only question in front of the Court in Bowers was whether the substantive component of the Due Process Clause protected a right to engage in homosexual sodomy. Bowers did not hold that moral disapproval of a group is a rational basis under the Equal Protection Clause to criminalize homosexual sodomy when heterosexual sodomy is not punished.
This case raises a different issue than Bowers: whether, under the Equal Protection Clause, moral disapproval is a legitimate state interest to justify by itself a statute that bans homosexual sodomy, but not heterosexual sodomy. It is not. Moral disapproval of this group, like a bare desire to harm the group, is an interest that is insufficient to satisfy rational basis review under the Equal Protection Clause. . . .
A law branding one class of persons as criminal solely based on the State's moral disapproval of that class and the conduct associated with that class runs contrary to the values of the Constitution and the Equal Protection Clause, under any standard of review. I therefore concur in the Court's judgment that Texas' sodomy law banning "deviate sexual intercourse" between consenting adults of the same sex, but not between consenting adults of different sexes, is unconstitutional.
Justice SCALIA, with whom Chief Justice REHNQUIST and Justice THOMAS join, dissenting.
. . . I begin with the Court's surprising readiness to reconsider a decision rendered a mere 17 years ago in Bowers v. Hardwick. I do not myself believe in rigid adherence to stare decisis in constitutional cases; but I do believe that we should be consistent rather than manipulative in invoking the doctrine. Today's opinions in support of reversal do not bother to distinguish or indeed, even bother to mention the paean to stare decisis coauthored by three Members of today's majority in Planned Parenthood v. Casey. There, when stare decisis meant preservation of judicially invented abortion rights, the widespread criticism of Roe was strong reason to reaffirm it. . . .
Today, however, the widespread opposition to Bowers, a decision resolving an issue as "intensely divisive" as the issue in Roe, is offered as a reason in favor of overruling it. . . .
I turn now to the ground on which the Court squarely rests its holding: the contention that there is no rational basis for the law here under attack. This proposition is so out of accord with our jurisprudence -indeed, with the jurisprudence of any society we know that it requires little discussion.
The Texas statute undeniably seeks to further the belief of its citizens that certain forms of sexual behavior are "immoral and unacceptable" the same interest furthered by criminal laws against fornication, bigamy, adultery, adult incest, bestiality, and obscenity. Bowers held that this was a legitimate state interest. The Court today reaches the opposite conclusion. The Texas statute, it says, "furthers no legitimate state interest which can justify its intrusion into the personal and private life of the individual." The Court embraces instead Justice Stevens' declaration in his Bowers dissent, that "the fact that the governing majority in a State has traditionally viewed a particular practice as immoral is not a sufficient reason for upholding a law prohibiting the practice." This effectively decrees the end of all morals legislation. If, as the Court asserts, the promotion of majoritarian sexual morality is not even a legitimate state interest, none of the above-mentioned laws can survive rational-basis review. . . .
Today's opinion is the product of a Court, which is the product of a law-profession culture, that has largely signed on to the so-called homosexual agenda, by which I mean the agenda promoted by some homosexual activists directed at eliminating the moral opprobrium that has traditionally attached to homosexual conduct. I noted in an earlier opinion the fact that the American Association of Law Schools (to which any reputable law school must seek to belong) excludes from membership any school that refuses to ban from its job-interview facilities a law firm (no matter how small) that does not wish to hire as a prospective partner a person who openly engages in homosexual conduct.
One of the most revealing statements in today's opinion is the Court's grim warning that the criminalization of homosexual conduct is "an invitation to subject homosexual persons to discrimination both in the public and in the private spheres." It is clear from this that the Court has taken sides in the culture war, departing from its role of assuring, as neutral observer, that the democratic rules of engagement are observed. Many Americans do not want persons who openly engage in homosexual conduct as partners in their business, as scoutmasters for their children, as teachers in their children's schools, or as boarders in their home. They view this as protecting themselves and their families from a lifestyle that they believe to be immoral and destructive. The Court views it as "discrimination" which it is the function of our judgments to deter. So imbued is the Court with the law profession's anti-anti-homosexual culture, that it is seemingly unaware that the attitudes of that culture are not obviously "mainstream"; that in most States what the Court calls "discrimination" against those who engage in homosexual acts is perfectly legal; that proposals to ban such "discrimination" under Title VII have repeatedly been rejected by Congress; that in some cases such "discrimination" is mandated by federal statute; and that in some cases such "discrimination" is a constitutional right, see Boy Scouts of America v. Dale, 530 U. S. 640 (2000).
Let me be clear that I have nothing against homosexuals, or any other group, promoting their agenda through normal democratic means. Social perceptions of sexual and other morality change over time, and every group has the right to persuade its fellow citizens that its view of such matters is the best. That homosexuals have achieved some success in that enterprise is attested to by the fact that Texas is one of the few remaining States that criminalize private, consensual homosexual acts. But persuading one's fellow citizens is one thing, and imposing one's views in absence of democratic majority will is something else. I would no more require a State to criminalize homosexual actsor, for that matter, display any moral disapprobation of themthan I would forbid it to do so. What Texas has chosen to do is well within the range of traditional democratic action, and its hand should not be stayed through the invention of a brand-new "constitutional right" by a Court that is impatient of democratic change. It is indeed true that "later generations can see that laws once thought necessary and proper in fact serve only to oppress"; and when that happens, later generations can repeal those laws. But it is the premise of our system that those judgments are to be made by the people, and not imposed by a governing caste that knows best.
One of the benefits of leaving regulation of this matter to the people rather than to the courts is that the people, unlike judges, need not carry things to their logical conclusion. The people may feel that their disapprobation of homosexual conduct is strong enough to disallow homosexual marriage, but not strong enough to criminalize private homosexual acts and may legislate accordingly. The Court today pretends that it possesses a similar freedom of action, so that that we need not fear judicial imposition of homosexual marriage. . . . At the end of its opinion after having laid waste the foundations of our rational basis jurisprudence the Court says that the present case "does not involve whether the government must give formal recognition to any relationship that homosexual persons seek to enter." Do not believe it. More illuminating than this bald, unreasoned disclaimer is the progression of thought displayed by an earlier passage in the Court's opinion, which notes the constitutional protections afforded to "personal decisions relating to marriage, procreation, contraception, family relationships, child rearing, and education," and then declares that "[p]ersons in a homosexual relationship may seek autonomy for these purposes, just as heterosexual persons do." Today's opinion dismantles the structure of constitutional law that has permitted a distinction to be made between heterosexual and homosexual unions, insofar as formal recognition in marriage is concerned. If moral disapprobation of homosexual conduct is "no legitimate state interest" for purposes of proscribing that conduct, and if, as the Court coos (casting aside all pretense of neutrality), "[w]hen sexuality finds overt expression in intimate conduct with another person, the conduct can be but one element in a personal bond that is more enduring," what justification could there possibly be for denying the benefits of marriage to homosexual couples exercising "[t]he liberty protected by the Constitution"? Surely not the encouragement of procreation, since the sterile and the elderly are allowed to marry. This case "does not involve" the issue of homosexual marriage only if one entertains the belief that principle and logic have nothing to do with the decisions of this Court. Many will hope that, as the Court comfortingly assures us, this is so.
The matters appropriate for this Court's resolution are only three: Texas's prohibition of sodomy neither infringes a "fundamental right" (which the Court does not dispute), nor is unsupported by a rational relation to what the Constitution considers a legitimate state interest, nor denies the equal protection of the laws. I dissent.
