A measure to repeal California's same-sex marriage ban won't be on the November ballot in The Golden State.

The gay rights activist group known as Restore Equality 2010 campaigned to put the initiative before voters, but failed to get enough signatures. Monday was the deadline for submitting the signatures to the Secretary of State's Office.

Restore Equality 2010 chairman Sean Bohac said Restore Equality's failed effort was undermined by the decision of more established gay rights groups not to participate in the campaign.

The group says it will now focus on trying to repeal the state's gay marriage ban in 2012.

A lawsuit to overturn Proposition 8 also is pending before a federal trial judge.
