Opinion of the Court
thoughtful District Court decisions addressing same-sex marriage—and most of them, too, have concluded same-sex couples must be allowed to marry. In addition the highest courts of many States have contributed to this ongoing dialogue in decisions interpreting their own State Constitutions. These state and federal judicial opinions are cited in Appendix A, infra.
After years of litigation, legislation, referenda, and the discussions that attended these public acts, the States are now divided on the issue of same-sex marriage. See Office of the Atty. Gen. of Maryland, The State of Marriage Equality in America, State-by-State Supp. (2015).

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.

In addition these liberties extend to certain personal choices central to individual dignity and autonomy, including intimate choices that define personal identity and beliefs.

The identification and protection of fundamental rights is an enduring part of the judicial duty to interpret the Constitution. That responsibility, however, “has not been reduced to any formula.” Poe v. Ullman, 367 U. S. 497, 542 (1961) (Harlan, J., dissenting). Rather, it requires courts to exercise reasoned judgment in identifying interests of the person so fundamental that the State must accord them its respect. See ibid. That process is guided by many of the same considerations relevant to analysis of other constitutional provisions that set forth broad principles rather than specific requirements.
