The U.S. Supreme Court has ruled it won't hear a case asking for the right for a citywide vote on gay marriage that might have led to an overhaul of the 2009 D.C. law allowing same sex couples to marry.

The high court's decision not to hear the case leaves standing a D.C. Court of Appeals ruling that found that a voter initiative to block same-sex marriages would illegally permit discrimination against gays and lesbians in the District.
