A U.S. appeals court has found California's gay marriage ban unconstitutional in a case that is likely to lead to a showdown on the issue in the U.S. Supreme Court.


Proponents of the ban said they would appeal the ruling, and the Protect Marriage coalition that sponsored the ban called the judgment "out of step with every other federal appellate and Supreme Court decision."


The appeal is likely to keep gay marriage on hold pending future proceedings. But gay marriage supporters celebrated.


Twitter is abuzz with talk about Prop 8. Here's a round-up about the best tweets from the afternoon by those who are celebrating.
