Judge overturns California's ban on same-sex marriage

Elated supporters of same-sex marriage gathered to celebrate the judge's opinion in the Castro district of San Francisco. After speeches and songs, they began a march to city hall. People waved rainbow flags and U.S. flags, and carried signs that read, "We all deserve the freedom to marry," and "Separate is Unequal." Similar rallies unfolded in cities across California -- including Los Angeles and San Diego.

"For our entire lives, our government and the law have treated us as unequal. This decision to ensure that our constitutional rights are as protected as everyone else's makes us incredibly proud of our country," said Kristin Perry, a plaintiff.

Perry and Sandy Stier, along with Jeffrey Zarrillo and Paul Katami, are the two couples at the heart of the case, which if appealed would go next to the 9th U.S. Circuit Court of Appeals before possibly heading to the U.S. Supreme Court.

Opponents of same-sex marriage have said their best bet lies with higher courts, and vowed to appeal the federal judge's ruling.

In a national survey, conducted by Gallup in May, 53 percent of respondents said same-sex marriages should not be recognized by law, while 44 percent said they should.

Proposition 8 is part of a long line of seesaw rulings, court cases, debates and protests over the controversial issue of same-sex marriage. It passed in California with some 52 percent of the vote in November 2008.

"Big surprise! We expected nothing different from Judge Vaughn Walker, after the biased way he conducted this trial," said Brian Brown, president of the National Organization for Marriage. "With a stroke of his pen, Judge Walker has overruled the votes and values of 7 million Californians who voted for marriage as one man and one woman."
