The Defense of Marriage Act (DOMA), enacted in 1996, states that, for the purposes of federal law, the words “marriage” and “spouse” refer to legal unions between one man and one woman. Since that time, some states have authorized same-sex marriage. In other cases regarding the DOMA, federal courts have ruled it unconstitutional under the Fifth Amendment, but the courts have disagreed on the rationale. Edith Windsor is the widow and sole executor of the estate of her late spouse, Thea Clara Spyer, who died in 2009. The two were married in Toronto, Canada, in 2007, and their marriage was recognized by New York state law. Thea Syper left her estate to her spouse, and because their marriage was not recognized by federal law, the government imposed $363,000 in taxes. Had their marriage been recognized, the estate would have qualified for a marital exemption, and no taxes would have been imposed. On November 9, 2010 Windsor filed suit in district court seeking a declaration that the Defense of Marriage Act was unconstitutional. At the time the suit was filed, the government’s position was that DOMA must be defended. On February 23, 2011, the President and the Attorney General announced that they would not defend DOMA. On April 18, 2011, the Bipartisan Legal Advisory Group of the House of Representatives filed a petition to intervene in defense of DOMA and motioned to dismiss the case. The district court denied the motion, and later held that DOMA was unconstitutional. The U.S. Court of Appeals for the Second Circuit affirmed.
