I thought they used the Due Process clause. Not Equal Protection (as other courts have done.)
Yes? No?
(I’ve read chunks of the majority and dissenting opinions.)
Here the marriage laws enforced by the respondents are in essence unequal: same-sex couples are denied all the benefits afforded to opposite-sex couples and are barred from exercising a fundamental right. 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. See, e.g., Zablocki, supra, at 383-388; Skinner, 316 U. S., at 541.These considerations 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.
