There are untold references to the beauty of marriage in religious and philosophical texts spanning time, cultures, and faiths, as well as in art and literature in all their forms. It is fair and necessary to say these references were based on the understanding that marriage is a union between two persons of the opposite sex. 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....
The petitioners acknowledge this history but contend that these cases cannot end there.... Far from seeking to devalue marriage, the petitioners seek it for themselves because of their respect—and need—for its privileges and responsibilities. And their immutable nature dictates that same-sex marriage is their only real path to this profound commitment....
The history of marriage is one of both continuity and change.... For example, marriage was once viewed as an arrangement by the couple’s parents based on political, religious, and financial concerns; but by the time of the Nation’s founding it was understood to be a voluntary contract between a man and a woman.... As the role and status of women changed, the institution further evolved. 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....
[T]he Court has long held the right to marry is protected by the Constitution... It cannot be denied that this Court’s cases describing the right to marry presumed a relationship involving opposite-sex partners. The Court, like many institutions, has made assumptions defined by the world and time of which it is a part.... In defining the right to marry these cases have identified essential attributes of that right based in history, tradition, and other constitutional liberties inherent in this intimate bond.... The four principles and traditions to be discussed demonstrate that the reasons marriage is fundamental under the Constitution apply with equal force to same-sex couples.
A first premise of the Court’s relevant precedents is that the right to personal choice regarding marriage is inherent in the concept of individual autonomy.... A second principle in this Court’s jurisprudence is that the right to marry is fundamental because it supports a two-person union unlike any other in its importance to the committed individuals. ... A third basis for protecting the right to marry is that it safeguards children and families and thus draws meaning from related rights of childrearing, procreation, and education.... Fourth and finally, this Court’s cases and the Nation’s traditions make clear that marriage is a keystone of our social order ...
Justice Kennedy expanded on the third of these premises:
Excluding same-sex couples from marriage thus conflicts with a central premise of the right to marry. Without the recognition, stability, and predictability marriage offers, their children suffer the stigma of knowing their families are somehow lesser. They also suffer the significant material costs of being raised by unmarried parents, relegated through no fault of their own to a more difficult and uncertain family life. The marriage laws at issue here thus harm and humiliate the children of same-sex couples. ...
Justice Kennedy went on:
[B]y 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....
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....
The right of same-sex couples to marry that is part of the liberty promised by the Fourteenth Amendment is derived, too, from that Amendment’s guarantee of the equal protection of the laws. The Due Process Clause and the Equal Protection Clause are connected in a profound way, though they set forth independent principles. Rights implicit in liberty and rights secured by equal protection may rest on different precepts and are not always coextensive, yet in some instances each may be instructive as to the meaning and reach of the other.... Especially against a long history of disapproval of their relationships, this denial to same-sex couples of the right to marry works a grave and continuing harm. The imposition of this disability on gays and lesbians serves to disrespect and subordinate them. And the Equal Protection Clause, like the Due Process Clause, prohibits this unjustified infringement of the fundamental right to marry....
Justice Kennedy then addressed the concerns of those who oppose same-sex marriage on religious grounds:
Finally, it must be emphasized that religions, and those who adhere to religious doctrines, may continue to advocate with utmost, sincere conviction that, by divine precepts, same-sex marriage should not be condoned. The First Amendment ensures that religious organizations and persons are given proper protection as they seek to teach the principles that are so fulfilling and so central to their lives and faiths, and to their own deep aspirations to continue the family structure they have long revered. The same is true of those who oppose same-sex marriage for other reasons. In turn, those who believe allowing same-sex marriage is proper or indeed essential, whether as a matter of religious conviction or secular belief, may engage those who disagree with their view in an open and searching debate. The Constitution, however, does not permit the State to bar same-sex couples from marriage on the same terms as accorded to couples of the opposite sex.Each of the 4 dissenting justices filed a separate dissent. A later posting will review those. UPDATE: Here is a posting summarizing the dissents.
