tion guide and discipline this inquiry but do not set its outer boundaries. See Lawrence, supra, at 572. That method respects our history and learns from it without allowing the past alone to rule the present.
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.
Applying these established tenets, the Court has long held the right to marry is protected by the Constitution. In Loving v. Virginia, 388 U. S. 1, 12 (1967), which invalidated bans on interracial unions, a unanimous Court held marriage is “one of the vital personal rights essential to the orderly pursuit of happiness by free men.” The Court reaffirmed that holding in Zablocki v. Redhail, 434 U. S. 374, 384 (1978), which held the right to marry was burdened by a law prohibiting fathers who were behind on child support from marrying. The Court again applied this principle in Turner v. Safley, 482 U. S. 78, 95 (1987), which held the right to marry was abridged by regulations limiting the privilege of prison inmates to marry. Over time and in other contexts, the Court has reiterated that the right to marry is fundamental under the Due Process Clause. See, e. g., M. L. B. v. S. L. J., 519 U. S. 102, 116 (1996); Cleveland Bd. of Ed. v. LaFleur, 414 U. S. 632, 639–640 (1974); Griswold, supra, at 486; Skinner v. Oklahoma ex rel. Williamson, 316 U. S. 535, 541 (1942); Meyer v. Nebraska, 262 U. S. 390, 399 (1923).
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,
