The U.S. Supreme Court has agreed to hear two challenges to state and federal laws dealing with the recognition of gay and lesbian couples to legally wed.
Oral arguments will likely be held in March, with a ruling expected by late June.
One appeal to be heard involves the federal Defense of Marriage Act (DOMA), which denies federal benefits to same-sex couples legally married in their own state. The second is a challenge to California's Proposition 8, a voter-approved referendum that took away the right of same-sex marriage that previously had been approved by state courts.
Currently, Maryland, Washington, Maine, Massachusetts, Connecticut, Iowa, Vermont, New Hampshire, New York and the District of Columbia issue marriage licenses to same-sex couples. Minnesota voters also rejected an effort to ban such unions through a constitutional amendment.
Five states – Delaware, Hawaii, Illinois, New Jersey and Rhode Island – currently allow civil unions that provide rights similar to marriage.

Civil Unions and Domestic Partnerships:
Civil unions grant couples most of the rights of state civil marriages, but provide none of the federal benefits of marriage, such as Social Security benefits. These rights include spousal support, medical decision-making privileges, access to a partner's insurance, and hospital visitation rights. Many cities and counties across the nation offer domestic partner registries that are open to gay couples or unmarried heterosexual couples.
