The nature of injustice is that we may not always see it in our own times. The generations that wrote and ratified the Bill of Rights and the Fourteenth Amendment did not presume to know the extent of freedom in all of its dimensions, and so they entrusted to future generations a charter protecting the right of all persons to enjoy liberty as we learn its meaning. When new insight reveals discord between the Constitution’s central protections and a received legal stricture, a claim to liberty must be addressed. …
The States have contributed to the fundamental character of the marriage right by placing that institution at the center of so many facets of the legal and social order.
There is no difference between same- and opposite-sex couples with respect to this principle. Yet by virtue of their exclusion from that institution, same-sex couples are denied the constellation of benefits that the States have linked to marriage. This harm results in more than just material burdens. Same-sex couples are consigned to an instability many opposite-sex couples would deem intolerable in their own lives. As the State itself makes marriage all the more precious by the significance it attaches to it, exclusion from that status has the effect of teaching that gays and lesbians are unequal in important respects. It demeans gays and lesbians for the State to lock them out of a central institution of the Nation’s society. Same-sex couples, too, may aspire to the transcendent purposes of marriage and seek fulfillment in its highest meaning. …
No union is more profound than marriage, for it embodies the highest ideals of love, fidelity, devotion, sacrifice, and family. In forming a marital union, two people become something greater than once they were. As some of the petitioners in these cases demonstrate, marriage embodies a love that may endure even past death. It would misunderstand these men and women to say they disrespect the idea of marriage. Their plea is that they do respect it, respect it so deeply that they seek to find its fulfillment for themselves. Their hope is not to be condemned to live in loneliness, excluded from one of civilization’s oldest institutions. They ask for equal dignity in the eyes of the law. The Constitution grants them that right.
The judgment of the Court of Appeals for the Sixth Circuit is reversed.
It is so ordered.
—From Justice Anthony Kennedy’s majority opinion in in Obergefell v. Hodges, a 5-4 ruling that now makes gay marriage legal across the United States.
