Federal Judge Vaughn Walker today struck down Proposition 8, the 2008-voter proposition that made gay marriage illegal in California. In his ruling, he called it unconstitutional. "Plaintiffs have demonstrated by overwhelming evidence that Proposition 8 violates their due process and equal protection rights and that they will continue to suffer these constitutional violations until state officials cease enforcement of Proposition 8. California is able to issue marriage licenses to same-sex couples, as it has already issued 18,000 marriage licenses to same-sex couples and has not suffered any demonstrated harm as a result."

This is the latest legal battle for supporters and opponents of Prop 8: The California Supreme Court approved it last year and now its supporters are expected to appeal the decision all the way to the Supreme Court. There's a rally tonight celebrating Walker's decision at 7 p.m. tonight (details), in front of the NYC Supreme Court building at 60 Centre Street.
