A federal judge in San Francisco will rule Wednesday on the right of same-sex couples to marry in California, court officials announced today.

Chief U.S. District Judge Vaughn Walker will decide whether Proposition 8, the November 2008 initiative that defined marriage as the union of a man and a woman, violated gays’ and lesbians’ right of equality under the U.S. Constitution.
