JUSTICE ANTHONY KENNEDY delivered the opinion of the Court.

{1}The Constitution promises liberty to all within its reach, a liberty that includes certain specific rights that allow persons, within a lawful realm, to define and express their identity.  The petitioners in these cases seek to find that liberty by marrying someone of the same sex and having their marriages deemed lawful on the same terms and conditions as marriages between persons of the opposite sex. . . .

Part II

{2}From their beginning to their most recent page, the annals of human history reveal the transcendent importance of marriage.  The lifelong union of a man and a woman always has promised nobility and dignity to all persons, without regard to their station in life.  Marriage is sacred to those who live by their religions and offers unique fulfillment to those who find meaning in the secular realm.  Its dynamic allows two people to find a life that could not be found alone, for a marriage becomes greater than just the two persons.   Rising from the most basic human needs, marriage is essential to our most profound hopes and aspirations.

{3}That history is the beginning of these cases. The respondents say it should be the end as well. To them, it would demean a timeless institution if the concept and lawful status of marriage were extended to two persons of the same sex. Marriage, in their view, is by its nature a gender-differentiated union of man and woman. This view long has been held -- and continues to be held--in good faith by reasonable and sincere people here and throughout the world.

{4}The petitioners acknowledge this history but contend that these cases cannot end there. Were their intent to demean the revered idea and reality of marriage, the petitioners' claims would be of a different order. But that is neither their purpose nor their submission. To the contrary, it is the enduring importance of marriage that underlies the petitioners' contentions. This, they say, is their whole point. Far from seeking to devalue marriage, the petitioners seek it for themselves because of their respect -- and need -- for its privileges and responsibilities. . . .

{5}The ancient origins of marriage confirm its centrality, but it has not stood in isolation from developments in law and society. The history of marriage is one of both continuity and change. That institution -- even as confined to opposite-sex relations--has evolved over time. . . . [For example,] under the centuries-old doctrine of coverture, a married man and woman were treated by the State as a single, male-dominated legal entity. As women gained legal, political, and property rights, and as society began to understand that women have their own equal dignity, the law of coverture was abandoned. These and other developments in the institution of marriage over the past centuries were not mere superficial changes. . . .

Part III

{6}Under the Due Process Clause of the Fourteenth Amendment, no State shall "deprive any person of life, liberty, or property, without due process of law." The fundamental liberties protected by this Clause include most of the rights enumerated in the Bill of Rights. . . . The identification and protection of fundamental rights is an enduring part of the judicial duty to interpret the Constitution. . . .

{7}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. . . . If rights were defined by who exercised them in the past, then received practices could serve as their own continued justification and new groups could not invoke rights once denied. This Court has rejected that approach, both with respect to the right to marry and the rights of gays and lesbians. . . .

{8}Many who deem same-sex marriage to be wrong reach that conclusion based on decent and honorable religious or philosophical premises, and neither they nor their beliefs are disparaged here. But when that sincere, personal opposition becomes enacted law and public policy, the necessary consequence is to put the imprimatur of the State itself on an exclusion that soon demeans or stigmatizes those whose own liberty is then denied. Under the Constitution, same-sex couples seek in marriage the same legal treatment as opposite-sex couples, and it would disparage their choices and diminish their personhood to deny them this right. . . .

{9}Considerations [outlined in the full text version of this opinion] lead to the conclusion that the right to marry is a fundamental right inherent in the liberty of the person, and under the Due Process and Equal Protection Clauses of the Fourteenth Amendment couples of the same-sex may not be deprived of that right and that liberty. The Court now holds that same-sex couples may exercise the fundamental right to marry.

{10}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.

CHIEF JUSTICE ROBERTS, with whom JUSTICE SCALIA and JUSTICE THOMAS join, dissenting:

{11}Petitioners make strong arguments rooted in social policy and considerations of fairness. They contend that same-sex couples should be allowed to affirm their love and commitment through marriage, just like opposite-sex couples. That position has undeniable appeal; over the past six years, voters and legislators in eleven States and the District of Columbia have revised their laws to allow marriage between two people of the same sex.

{12}But this Court is not a legislature. Whether same-sex marriage is a good idea should be of no concern to us. . . . Although the policy arguments for extending marriage to same-sex couples may be compelling, the legal arguments for requiring such an extension are not. The fundamental right to marry does not include a right to make a State change its definition of marriage. And a State's decision to maintain the meaning of marriage that has persisted in every culture throughout human history can hardly be called irrational. In short, our Constitution does not enact any one theory of marriage. The people of a State are free to expand marriage to include same-sex couples, or to retain the historic definition.

{13}Today, however, the Court takes the extraordinary step of ordering every State to license and recognize same-sex marriage. Many people will rejoice at this decision, and I begrudge none their celebration. But for those who believe in a government of laws, not of men, the majority's approach is deeply disheartening. Supporters of same-sex marriage have achieved considerable success persuading their fellow citizens--through the democratic process--to adopt their view. That ends today. Five lawyers have closed the debate and enacted their own vision of marriage as a matter of constitutional law. Stealing this issue from the people will for many cast a cloud over same-sex marriage, making a dramatic social change that much more difficult to accept.

{14}If you are among the many Americans -- of whatever sexual orientation -- who favor expanding same-sex marriage, by all means celebrate today's decision. Celebrate the achievement of a desired goal. Celebrate the opportunity for a new expression of commitment to a partner. Celebrate the availability of new benefits. But do not celebrate the Constitution. It had nothing to do with it.

{15}I respectfully dissent.

JUSTICE SCALIA, with whom JUSTICE THOMAS joins, dissenting:

{16}. . . The substance of today's decree is not of immense personal importance to me. The law can recognize as marriage whatever sexual attachments and living arrangements it wishes. . . . It is of overwhelming importance, however, who it is that rules me. Today's decree says that my Ruler, and the Ruler of 320 million Americans coast-to-coast, is a majority of the nine lawyers on the Supreme Court. . . .  [This opinion represents the Court's creating] "liberties" that the Constitution and its Amendments neglect to mention. This practice of constitutional revision by an unelected committee of nine, always accompanied (as it is today) by extravagant praise of liberty, robs the People of the most important liberty they asserted in the Declaration of Independence and won in the Revolution of 1776: the freedom to govern themselves.

{17}Until the courts put a stop to it, public debate over same-sex marriage displayed American democracy at its best. Individuals on both sides of the issue passionately, but respectfully, attempted to persuade their fellow citizens to accept their views. Americans considered the arguments and put the question to a vote. The electorates of 11 States, either directly or through their representatives, chose to expand the traditional definition of marriage. Many more decided not to. Win or lose, advocates for both sides continued pressing their cases, secure in the knowledge that an electoral loss can be negated by a later electoral win. That is exactly how our system of government is supposed to work. . . .

{18}What really astounds is the hubris reflected in today's judicial Putsch. The five Justices who compose today's majority are entirely comfortable concluding that every State violated the Constitution for all of the 135 years between the Fourteenth Amendment's ratification and Massachusetts' permitting of same-sex marriages in 2003. They have discovered in the Fourteenth Amendment a "fundamental right" overlooked by every person alive at the time of ratification, and almost everyone else in the time since. . . . They are certain that the People ratified the Fourteenth Amendment to bestow on them the power to remove questions from the democratic process when that is called for by their "reasoned judgment." These Justices know that limiting marriage to one man and one woman is contrary to reason; they know that an institution as old as government itself, and accepted by every nation in history until 15 years ago, cannot possibly be supported by anything other than ignorance or bigotry. And they are willing to say that any citizen who does not agree with that, who adheres to what was, until 15 years ago, the unanimous judgment of all generations and all societies, stands against the Constitution.

{19}The opinion is couched in a style that is as pretentious as its content is egotistic. [added in a footnote:] If, even as the price to be paid for a fifth vote, I ever joined an opinion for the Court that began: "The Constitution promises liberty to all within its reach, a liberty that includes certain specific rights that allow persons, within a lawful realm, to define and express their identity," I would hide my head in a bag.
