Legal challenges ensue in federal court, and plans are afoot for a 2010 ballot measure to undo Proposition 8.
The court says the measure only takes away the term 'marriage' – not a gay couple's legal rights. The ruling also preserves 18,000 marriages that took place before the ban.
But it's unclear if the Freedom of Choice Act imperils a doctor's right not to perform the procedure.
Beyond the anger over the church's support for a gay-marriage ban in California, some seek dialogue.
Voters in Florida and Arizona also approved similar bans in a setback for the gay rights movement.
