SAN FRANCISCO Even as same-sex couples across California begin making plans to tie the knot, opponents are redoubling their efforts to make sure wedding bells never again ring for gay couples in the nation's most populous state.
A conservative group said it would ask California's Supreme Court to postpone putting its Thursday decision legalizing gay marriage into effect until after the fall election. That's when voters will likely have a chance to weigh in on a proposed amendment to California's constitution that would bar same-sex couples from getting married.
If the court does not put its ruling on hold, gay marriages could begin in California in as little as 30 days, the time it typically takes for the justices' opinions to become final.
The Republican-dominated court's decision, which cited a 1948 California Supreme Court decision that overturned a ban on interracial marriages, swept away decades of tradition and said there was no legally justifiable reason why the state should withhold the institution of marriage because of a couple's sexual orientation.
The 4-3 opinion written by Chief Justice Ronald George said domestic partnerships that provide many of the rights and benefits of matrimony are not enough.
"In contrast to earlier times, our state now recognizes that an individual's capacity to establish a loving and long-term committed relationship with another person and responsibly to care for and raise children does not depend upon the individual's sexual orientation," George wrote for the majority in ringing language that delighted gay rights activists.
Gay marriage opponents, meanwhile, derided the ruling as an example of judicial overreaching in which the opinions of a few justices trumped the will of Californians.
"The remedy is a constitutional amendment," said Glen Lavy, senior counsel for the Alliance Defense Fund, which is pushing for the stay.
The last time the state's voters were asked to express their views on same-sex marriage at the ballot box was in 2000, the year after the Legislature enacted the first of a series of laws awarding spousal rights to domestic partners.
Proposition 22, which strengthened the state's 1978 one-man, one-woman marriage law with the words "Only marriage between a man and a woman is valid or recognized in California," passed with 61 percent of the vote.
The Supreme Court's ruling Thursday struck down both statutes.
Still, backers of a proposed November ballot measure that would allow Californians to vote on a constitutional amendment banning same-sex marriage said the court's decision would ultimately help their cause.
"(The ruling) is not the way a democracy is supposed to handle these sorts of heartfelt, divisive issues," said Brian Brown of the National Organization for Marriage, one of the groups helping to underwrite the gay marriage ban campaign. "I do think it will activate and energize Californians. I'm more confident than ever that we will be able to pass this amendment come November."
Twenty-six states have approved constitutional amendments banning same-sex marriage.
In the past few years, courts in New York, Maryland and Washington state have refused to allow gay marriage, and New Jersey's highest court gave the state lawmakers the option of establishing civil unions as an alternative.
Massachusetts is the only other state to legalize gay marriage, something it did in 2004. More than 9,500 same-sex couples in that state have wed. The California ruling is considered monumental because of the state's population 38 million out of a U.S. population of 302 million and its historical role as the vanguard of many social and cultural changes that have swept the country since World War II.
California has an estimated 108,734 same-sex households, according to 2006 census figures.
"It's about human dignity. It's about human rights. It's about time in California," San Francisco Mayor Gavin Newsom told a roaring crowd at City Hall after the ruling was issued. "As California goes, so goes the rest of the nation. It's inevitable. This door's wide open now. It's going to happen, whether you like it or not."
The case was set in motion in 2004 when Newsom threw open City Hall to gay couples to get married in a calculated challenge to California law. Four thousand wed before the Supreme Court put a halt to the practice after a month.
Two dozen gay couples then sued, along with the city and gay rights organizations.
Gareth Lacy, a spokesman for Attorney General Jerry Brown, whose office argued to uphold the ban, said Brown would "work with the governor and other state agencies to implement the ruling."
The justices said they would direct state officials "to take all actions necessary to effectuate our ruling," including requiring county marriage clerks to carry out their duties "in a manner consistent with the decision of this court."
By Thursday afternoon, gay and lesbian couples had already started lining up at San Francisco City Hall to make appointments to get marriage licenses. The county clerk's office in Los Angeles issued a statement saying it was awaiting legal analysis of the ruling and a timeline for implementation.
California's secretary of state is expected to rule by the end of June whether the sponsors of the anti-gay marriage ballot measure gathered enough signatures to put the amendment on the ballot.
Thursday's ruling could alter the dynamics of the presidential race, as well as state and congressional contests in California and beyond, by causing a backlash among conservatives and drawing them to the polls in large numbers.
Republican Gov. Arnold Schwarzenegger, who has twice vetoed legislation that would have granted marriage to same-sex couples, said in a statement he respected the court's decision and "will not support an amendment to the constitution that would overturn this state Supreme Court ruling."
