14th Amendment- Equal Protection Clause-Civil Rights Act 1964

The Conclusion
Yes, yes. Justice Anthony M. Kennedy delivered the opinion for the 5-4 majority. The Court held that the Due Process Clause of the Fourteenth Amendment guarantees the right to marry as one of the fundamental liberties it protects, and that analysis applies to same-sex couples in the same manner as it does to opposite-sex couples. Judicial precedent has held that the right to marry is a fundamental liberty because it is inherent to the concept of individual autonomy, it protects the most intimate association between two people, it safeguards children and families by according legal recognition to building a home and raising children, and it has historically been recognized as the keystone of social order. Because there are no differences between a same-sex union and an opposite-sex union with respect to these principles, the exclusion of same-sex couples from the right to marry violates the Due Process Clause of the Fourteenth Amendment. The Equal Protection Clause of the Fourteenth Amendment also guarantees the right of same-sex couples to marry as the denial of that right would deny same-sex couples equal protection under the law. Marriage rights have traditionally been addressed through both parts of the Fourteenth Amendment, and the same interrelated principles of liberty and equality apply with equal force to these cases; therefore, the Constitution protects the fundamental right of same-sex couples to marry. The Court also held that the First Amendment protects the rights of religious organizations to adhere to their principles, but it does not allow states to deny same-sex couples the right to marry on the same terms as those for opposite-sex couples.
