People rally in front of the California Supreme Court Building as arguments are heard for and against Proposition 8 on March 5, 2009.
California's largest gay rights group has decided against trying to have the state's voter-approved ban on same-sex unions overturned next year.
Equality California announced Wednesday that it would not lead a ballot campaign to undo Proposition 8.
The constitutional amendment limited marriage to a man and a woman five months after the state Supreme Court legalized same-sex marriages.
Executive Director Roland Palencia says polls show voters are still divided and a court challenge that could overturn the measure is still pending. As a result, he says the time is not right to undertake a risky and expensive ballot fight.
Instead, Equality California plans to devote its resources to a public education and messaging campaign to counter beliefs that allowing gay and lesbian couples to marry harms children.
