Months before the State Supreme Court's ruling, groups who opposed same-sex marriage began circulating initiative petitions. One petition, #07-0068 (titled the "California Marriage Protection Act" by its proponents and the "Limit on Marriage" amendment by the California Attorney General on the actual ballot) gathered an estimated 764,063 valid signatures and qualified for the November 4, 2008 ballot as Proposition 8. The measure added § 7.5 to Article I of the California Constitution to replace the newly unenforceable Family Code § 308.5. It superseded the part of the Supreme Court's holding that authorized the granting of marriage licenses to same-sex couples. Twelve other proposed amendments since 2004 had failed to qualify to be on the ballot. The ability of the voters to remove a fundamental constitutional right by initiative amendment was challenged. A lawsuit filed on those grounds asking for the removal of Proposition 8 from the ballot was dismissed on July 16, 2008.
