A federalism scholar explains why federalism isn't the issue in Hollingsworth and Windsor.
Federalism is once again at the forefront of the Supreme Court’s most contentious cases this Ter
m. The cases attracting most attention are the two same-sex marriage cases that were argued this week. Facing intense public sentiment on both sides of the issue and the difficult questions they raise about the boundary between state and federal authority, some justices openly questioned whether they should just defer to the political process. And while this is often a wise prudential approach in review of contested federalism-sensitive policymaking, it’s exactly the wrong course of action when the matter at hand is an individual right.
While both cases raise curious issues of standing, the substantive issue at the heart of each case is whether same-sex couples should be able to marry. Hollingsworth v. Perry asks the Court to review the constitutionality of a California’s “Prop 8,” a ballot initiative banning same-sex marriages within the state. United States v. Windsor tests the constitutionality of the Defense of Marriage Act (DOMA), a federal law that prevents the U.S. government from recognizing same-sex marriages performed in states that allow it (and affecting the administration of some 1,100 federal benefits connected with marriage).
Yet the looming question for the Supreme Court is not just whether gays and lesbians have the right to marry -- the justices must also confront the question of who should decide whether same-sex couples can marry. Is this something that states should be able to decide for themselves, by making and interpreting state law? (After all, matters of family law have traditionally been left to state regulation.) Or, is the decision to marry so fundamentally important that it triggers the federal Constitution’s promise that all citizens will be treated equally under the law? (After all, even though family law is traditionally left to the states, the Constitution won’t allow them to deny interracial marriages.)
