United States v. Windsor (U.S. Supreme Court)
The question presented in this case was whether Section 3 of the Defense of Marriage Act, which prohibits the federal recognition of same-sex marriages that are recognized under state law, violated the Equal Protection Clause. The Second Circuit held that the statute is unconstitutional. On behalf of a 40 U.S. Senators and 172 Members of the U.S. House of Representatives—many of whom had voted in support of DOMA when it was enacted in 1996—we filed an amicus brief arguing that Section 3 of DOMA should be invalidated. The Court affirmed on grounds consistent with those we advocated.
