Proposition 8 — which ruled same-sex couples could not marry in California — was overturned in the state today by a judge claiming the proposition was unconstitutional. Judge Vaughn R. Walker ruled that due-process and equal-protection clauses conflicted with the proposition.

The overturning of the 2008 proposition was fueled by several Hollywood figures, like Bruce Cohen, Rob Reiner, and Dustin Lance Black, who all encouraged attorneys Theodore Olson and David Boies to head the case, The Hollywood Reporter reports. “It was a great moment,” Cohen said. “We were hoping that Judge Walker, when he heard all the evidence which we heard in court, would come to the conclusion that there is no doubt that Proposition 8 is unconstitutional, but to have it be official and to see it…is incredibly thrilling and exciting.”

Several other celebs went to Twitter to celebrate the announcement. Ellen DeGeneres Tweeted, “Equality won!” while wife Portia de Rossi wrote, “I am ecstatic that proposition 8 has been overturned in the state of California. This is an incredibly exciting and historical day and a big step towards equal rights for all.” Even Gov. Arnold Schwarzenegger took to his Twitter: “This decision affirms the full legal protections and safeguards I believe everyone deserves.”
