Announcement of ruling: implementing United States v.Windsor for purposes of entitlement and enrollment in Medicare hospital insurance and supplementary medical insurance. Notice of CMS ruling.

This document announces a CMS Ruling that states the CMS policies for implementing United States v. Windsor ("Windsor''), in which the Supreme Court held that section 3 of the Defense of Marriage Act (DOMA), enacted in 1996, is unconstitutional. Section 3 of DOMA defined ``marriage'' and "spouse'' as excluding same-sex marriages and same-sex spouses, and effectively precluded the Federal government from recognizing same-sex marriages and spouses.
