We granted certiorari, 537 U.S. 1044 (2002), to consider three questions:
“1. Whether Petitioners’ criminal convictions under the Texas “Homosexual Conduct” law–which criminalizes sexual intimacy by same-sex couples, but not identical behavior by different-sex couples–violate the Fourteenth Amendment guarantee of equal protection of laws?
“2. Whether Petitioners’ criminal convictions for adult consensual sexual intimacy in the home violate their vital interests in liberty and privacy protected by the Due Process Clause of the Fourteenth Amendment?
“3. Whether Bowers v. Hardwick, 478 U.S. 186 (1986), should be overruled?” Pet. for Cert. i.
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.
There are broad statements of the substantive reach of liberty under the Due Process Clause in earlier cases, including Pierce v. Society of Sisters, 268 U.S. 510 (1925), and Meyer v. Nebraska, 262 U.S. 390 (1923); but the most pertinent beginning point is our decision in Griswold v. Connecticut, 381 U.S. 479 (1965).
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. Id., at 485.
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 case was decided under the Equal Protection Clause, id., at 454; but with respect to unmarried persons, the Court went on to state the fundamental proposition that the law impaired the exercise of their personal rights, ibid. It quoted from the statement of the Court of Appeals finding the law to be in conflict with fundamental human rights, and it followed with this statement of its own:
“It is true that in Griswold the right of privacy in question inhered in the marital relationship… . 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.” Id., at 453.

The case was decided on Due Process/Privacy grounds, not Equal Protection.
