Opinion of the Court
the recognition that laws excluding same-sex couples from the marriage right impose stigma and injury of the kind prohibited by our basic charter.
Objecting that this does not reflect an appropriate framing of the issue, the respondents refer to Washington v. Glucksberg, 521 U. S. 702, 721 (1997), which called for a “‘careful description’” of fundamental rights. They assert the petitioners do not seek to exercise the right to marry but rather a new and nonexistent “right to same-sex marriage.” Brief for Respondent in No. 14–556, p. 8. Glucksberg did insist that liberty under the Due Process Clause must be defined in a most circumscribed manner, with central reference to specific historical practices. Yet while that approach may have been appropriate for the asserted right there involved (physician-assisted suicide), it is inconsistent with the approach this Court has used in discussing other fundamental rights, including marriage and intimacy. Loving did not ask about a “right to interracial marriage”; Turner did not ask about a “right of inmates to marry”; and Zablocki did not ask about a “right of fathers with unpaid child support duties to marry.” Rather, each case inquired about the right to marry in its comprehensive sense, asking if there was a sufficient justification for excluding the relevant class from the right. See also Glucksberg, 521 U. S., at 752–773 (Souter, J., concurring in judgment); id., at 789–792 (Breyer, J., concurring in judgments).
That principle applies here. 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. See Loving, 388 U. S., at 12; Lawrence, 539 U. S., at 566–567.
The right to marry is fundamental as a matter of history and tradition, but rights come not from ancient sources
