1. the whole realm of federal regulations, has a far greater reach. Its operation is also directed to a class of persons that the laws of New York, and of 11 other States, have sought to protect. Assessing the validity of that intervention requires discussing the historical and traditional extent of state power and authority over marriage.

   Subject to certain constitutional guarantees, see, e.g., Loving v. Virginia, 388 U.S. 1, "regulation of domestic relations" is "an area that has long been regarded as a virtually exclusive province of the States," Sosna v. Iowa, 419 U.S. 393, 404. The significance of state responsibilities for the definition and regulation of marriage dates to the Nation's beginning; for "when the Constitution was adopted the common understanding was that the domestic relations of husband and wife and parent and child were matters reserved to the States," Ohio ex rel. Popovici v. Agler, 280 U.S. 379, 383–384. Marriage laws may vary from State to State, but they are consistent within each State.

   DOMA rejects this long-established precept. The State's decision to give this class of persons the right to marry conferred upon them a dignity and status of immense import. But the Federal Government uses the state-defined class for the opposite purpose—to impose restrictions and disabilities. The question is whether the resulting injury and indignity is a deprivation of an essential part of the liberty protected by the Fifth Amendment, since what New York treats as alike the federal law deems unlike by a law designed to injure the same class the State seeks to protect. New York's actions were a proper exercise of its sovereign authority. They reflect both the community's considered perspective on the historical roots of the institution of marriage and its evolving understanding of the meaning of equality. Pp. 13–20.

   (b) By seeking to injure the very class New York seeks to protect, DOMA violates basic due process and equal protection principles applicable to the Federal Government. The Constitution's guarantee of equality "must at the very least mean that a bare congressional desire to harm a politically unpopular group cannot" justify disparate treatment of that group. Department of Agriculture v. Moreno, 413 U.S. 528, 534–535. DOMA cannot survive under these principles. Its unusual deviation from the tradition of recognizing and accepting state definitions of marriage operates to deprive same-sex couples of the benefits and responsibilities that come with federal recognition of their marriages. This is strong evidence of a law having the purpose and effect of disapproval of a class recognized and protected by state law. DOMA's avowed purpose and practical effect are to impose a disadvantage, a separate status, and so a stigma upon all who enter into same-sex marriages made lawful by the unquestioned authority
