- O'Malley's signature authorizes same-sex marriage in Maryland
- Voters in Minnesota and North Carolina will consider proposals in November
- New Jersey lawmakers approved same-sex marriage this month, but it was vetoed
- Neither side in the same-sex marriage debate is declaring victory
Maryland became the eighth U.S. state to allow same-sex marriage Thursday as Gov. Martin O'Malley signed legislation he said secures the "human dignity" of all residents, including gay and lesbian couples.
A standing-room crowd in the Maryland State House cheered O'Malley as he emerged from his office to sign the legislation, flanked by state Senate President Mike Miller and House Speaker Michael Busch.
"The way forward is always found through greater respect for the equal rights of all," the governor said.
Six states and the District of Columbia already issue same-sex marriage licenses -- Connecticut, Iowa, Massachusetts, New Hampshire, New York and Vermont. Five states -- Delaware, Hawaii, Illinois, New Jersey and Rhode Island -- allow civil unions that provide rights similar to marriage.
The Maryland House of Delegates approved the measure O'Malley signed Thursday less than two weeks after Washington state legislators voted to legalize same-sex marriage. That measure will take effect in the summer if it survives a likely court challenge.
New Jersey lawmakers approved same-sex marriage this month, but Gov. Chris Christie vetoed the legislation. He has said voters should decide the issue in a statewide referendum.
Voters in North Carolina and Minnesota, meanwhile, will consider proposals in May and November, respectively, to ban gay marriage in those states. New Hampshire lawmakers may also consider a repeal of its same-sex marriage law, according to the National Organization for Marriage, which opposes same-sex marriage. Lawsuits seeking to expand civil unions or turn back laws banning same-sex marriages are working through the courts in at least 12 states, including Hawaii, Minnesota and California, the organization said.
Same-sex marriage became a national issue in 1993, after the Hawaii Supreme Court ruled that a ban on such unions violated the state constitution.
Legislation was introduced recently to allow same-sex marriages in Illinois, and bills from 2011 remain technically active in Hawaii and Minnesota, said Jack Tweedie of the National Council of State Legislatures. It's unclear whether any will see significant action, he said.
An effort is also under way to put a proposal to legalize same-sex marriage on the November ballot in Maine, where voters previously overturned a 2009 state law authorizing it.
In California, meanwhile, a federal appeals court recently ruled against a voter-passed referendum that outlawed same-sex marriage. It said such a ban was unconstitutional and singled out gays and lesbians for discrimination. The case appears to be eventually headed to the U.S. Supreme Court.
