After a morning of uncertainty [1] it has been confirmed that California has passed Prop 8 [2], which would change the state Constitution to ban same-sex marriage.

The ban had 5,125,752 votes, or 52 percent, while there were 4,725,313 votes, or 48 percent, opposed.

California legalized gay marriage earlier this year [3], but the constitutional amendment will limit marriage to heterosexual couples. Similar bans have been set in 27 states, but none of those states had previously legalized marriage. Update: Opponents have already filed suit [4] in an attempt to stop the measure from taking effect.
