United States v. Windsor invalidated Section 3 of DOMA, which denied federal recognition to same-sex marriages valid under state law. The decision required the federal government to recognize lawful same-sex marriages but did not yet require all states to license them.
Canonical active row after archiving duplicate long-party row. Windsor should be framed as federal recognition of state-law marriages, not the final nationwide marriage-equality decision; Obergefell later supplied that rule.
Does Section 3 of DOMA violate the Fifth Amendment by refusing federal recognition to same-sex marriages that are lawful under state law?
Section 3 of the Defense of Marriage Act violates the Fifth Amendment because it denies equal liberty to same-sex couples whose marriages are lawful under state law.
How the justices lined up in this decision.
The decision changed federal treatment of lawfully married same-sex couples across taxes, immigration, Social Security, veterans benefits, health care, and other federal programs. It also weakened the legal foundation for state marriage bans and became a bridge between earlier LGBTQ-rights cases and Obergefell. Families who were married under state law could no longer be treated as unmarried by the federal government.
