The State Supreme Court in California has voted 6-1 to uphold Proposition 8, a ballot initiative that banned gay marriage in the state last November. But in upholding the law, the court also agreed to validate the 18,000 same-sex marriages that took place between June of last year when gay marriage was legalized (by the same court) and November, when Prop 8 was passed by the voters.

The decision was announced minutes ago before an angry crowd outside the San Francisco courthouse. Legal analysts are currently poring over the decision, so expect more details on the ruling to come, as well as plenty of protests—same-sex marriage advocates have promised to engage in civil disobedience if the court upheld Prop. 8, and CBS News reports that demonstrators are currently blocking traffic in San Francisco.

Update: Gay City News reports that at 6 p.m., "advocates led by Marriage Equality New York, a grassroots group, will gather at Sheridan Square, Seventh Avenue South at Christopher Street, for a march to Union Square Park."
