SAN FRANCISCO -- The advocacy group backing California's ban on gay marriage said Tuesday it would take the case to the US Supreme Court.
The announcement came after the US Ninth Circuit Court of Appeals ruled Tuesday that it was declining to revisit a decision that struck down California's ban on gay marriage, known as "Proposition 8."
Advocacy group Protectmarriage.com is seeking to reverse a 2-1 ruling by a panel of Ninth Circuit judges in February that held that "Proposition 8" violated the equal protection rights of gay men and women guaranteed by the US Constitution.
California voters passed Proposition 8 to amend the state's constitution in November 2008 with 52 percent of the vote.
"Marriage is a universal good that has been honored by diverse cultures and faiths for the entire history of Western Civilization," attorney Brian Raum said in a statement.
"The Protectmarriage.com legal team looks forward to standing before the U.S. Supreme Court on behalf of the people's right to preserve the fundamental building block of civilization, especially since the dissents accompanying today's decision strongly support our arguments. The democratic process and the most important human institution -- marriage -- shouldn't be overthrown based on the demands of Hollywood activists."
