The Court's conclusion that this petition may be heard on the merits does not imply that no difficulties would ensue if this were a common practice in ordinary cases. The Executive's failure to defend the constitutionality of an Act of Congress based on a constitutional theory not yet established in judicial decisions has created a procedural dilemma. On the one hand, as noted, the Government's agreement with Windsor raises questions about the propriety of entertaining a suit in which it seeks affirmance of an order invalidating a federal law and ordering the United States to pay money. On the other hand, if the Executive's agreement with a plaintiff that a law is unconstitutional is enough to preclude judicial review, then the Supreme Court's primary role in determining the constitutionality of a law that has inflicted real injury on a plaintiff who has brought a justiciable legal claim would become only secondary to the President's. This would undermine the clear dictate of the separation-of-powers principle that "when an Act of Congress is alleged to conflict with the Constitution, ‘[i]t is emphatically the province and duty of the judicial department to say what the law is.'" Zivotofsky v. Clinton, 566 U. S. ___, ___ (2012) (slip op., at 7) (quoting Marbury v. Madison, 1 Cranch 137, 177 (1803)). Similarly, with respect to the legislative power, when Congress has passed a statute and a President has signed it, it poses grave challenges to the separation of powers for the Executive at a particular moment to be able to nullify Congress' enactment solely on its own initiative and without any determination from the Court.
The class to which DOMA directs its restrictions and restraints are those persons who are joined in same-sex marriages made lawful by the State. DOMA singles out a class of persons deemed by a State entitled to recognition and protection to enhance their own liberty. It imposes a disability on the class by refusing to acknowledge a status the State finds to be dignified and proper. DOMA instructs all federal officials, and indeed all persons with whom same-sex couples interact, including their own children, that their marriage is less worthy than the marriages of others. The federal statute is invalid, for no legitimate purpose overcomes the purpose and effect to disparage and to injure those whom the State, by its marriage laws, sought to protect in personhood and dignity. By seeking to displace this protection and treating those persons as living in marriages less respected than others, the federal statute is in violation of the Fifth Amendment. This opinion and its holding are confined to those lawful marriages.
Pages 1-2 of the Scalia DissentThis case is about power in several respects. It is about the power of our people to govern themselves, and the power of this Court to pronounce the law. Today's opinion aggrandizes the latter, with the predictable consequence of diminishing the former. We have no power to decide this case. And even if we did, we have no power under the Constitution to invalidate this democratically adopted legislation. The Court's errors on both points spring forth from the same diseased root: an exalted conception of the role of this institution in America.. . .The Court is eager-hungry-to tell everyone its view of the legal question at the heart of this case. Standing in the way is an obstacle, a technicality of little interest to anyone but the people of We the People, who created it as a barrier against judges' intrusion into their lives. They gave judges, in Article III, only the "judicial Power," a power to decide not abstract questions but real, concrete "Cases" and "Controversies." Yet the plaintiff and the Government agree entirely on what should happen in this lawsuit. They agree that the court below got it right; andthey agreed in the court below that the court below that one got it right as well. What, then, are we doing here?
Page 26 of Scalia DissentSome will rejoice in today's decision, and some will despair at it; that is the nature of a controversy that matters so much to so many. But the Court has cheated both sides, robbing the winners of an honest victory, and the losers of the peace that comes from a fair defeat. We owed both of them better. I dissent.
Page 12 of Alito DissentWhat Windsor and the United States seek, therefore, is not the protection of a deeply rooted right but the recognition of a very new right, and they seek this innovation not from a legislative body elected by the people, but from unelected judges. Faced with such a request, judges have cause for both caution and humility.The family is an ancient and universal human institution. Family structure reflects the characteristics of a civilization, and changes in family structure and in the popular understanding of marriage and the family can have profound effects. Past changes in the understand-ing of marriage-for example, the gradual ascendance of the idea that romantic love is a prerequisite to marriage- have had far-reaching consequences. But the process by which such consequences come about is complex, involving the interaction of numerous factors, and tends to occur over an extended period of time.
