United States v. Windsor, 570 U.S. ___ (2013) (Docket No. 12-307) is a U.S. Supreme Court case that held Section 3 of the Defense of Marriage Act (DOMA) to be unconstitutional under the Due Process Clause of the Fifth Amendment. The decision held that in restricting federal interpretation of "marriage" and "spouse" to only apply to marriages between opposite sex couples, the law "disparege[s] and ... injure[s] those whom the State, by its marriage laws, sought to protect in personhood and dignity."
