The Defense of Marriage Act (DOMA) was a federal law passed by the 104th United States Congress intended to define and protect the institution of marriage. This law specifically defined marriage as the union of one man and one woman which allowed individual states to not recognize same-sex marriages that were performed and recognized under other states’ laws. Nonetheless, this law's sections were ruled unconstitutional by the United States Supreme in cases such as United States v. Windsor (2013) and Obergefell v. Hodges (2015).
This law specifically stated that "the word 'spouse' refers only to a person of the opposite sex who is a husband or a wife” and further states that “[i]n determining the meaning of any Act of Congress, or of any ruling, regulation, or interpretation of the various administrative bureaus and agencies of the United States, the word 'marriage' means only a legal union between one man and one woman as husband and wife, and the word 'spouse' refers only to a person of the opposite sex who is a husband or a wife.”
The implications of this law were that it denied a large number of benefits and recognition to same-sex couples that opposite-sex couples enjoyed. These benefits included but were not limited to over 1,000 federal protections and privileges such as access to a spouse’s employment benefits, the recognition of the marriage itself, the rights of inheritance, joint tax returns and exemptions, and the right to cohabit together in a college or military housing.
In fact, DOMA authorized that states that banned same-sex marriage did not have to recognize same-sex marriages that were performed in other states and further specified that in regards to federal law, marriage is only between a man and a woman. This law had overwhelming support within Congress while there was speculation that Hawaii was going to soon recognize same-sex marriage, which could force or prompt other states to recognize same-sex marriages that occurred in Hawaii. President Bill Clinton signed DOMA into law on September 21, 1996. Afterwards, about 40 states enacted specific bans on same-sex marriage.
One of the major provisions of this law was that a nonbiological parent could not have a legal relationship with a child of the biological parent in a same-sex couple. Moreover, same-sex couples could not take medical leave to care for their partners or nonbiological children. They also could not adopt children and during divorce proceedings, they could not petition the court for custody, visitation rights, or child support.
The supporters of DOMA believed that opposite-sex marriage was the only appropriate method for family formation and procreation. One of the major arguments from proponents of DOMA was that same-sex marriage could lead to alternative family formations and could even result in incestuous relationships and polygamous marriage. On the other hand, the opponents of DOMA claimed that DOMA’s definition of marriage as only between one man and one woman and other arguments were discriminatory on the basis of sex, and equated homosexuality with incest and polygamy.
In 2013 in United States v. Windsor, the U.S. Supreme court struct down DOMA’s definition of marriage as only between one man and one woman. Furthermore, in 2015 in Obergefell v. Hodges, the Supreme Court struck down the section of DOMA that allowed individual states to not recognize same-sex marriages performed in other states. This result granted same-sex couples the constitutional right to marry.
