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. A spokeswoman for the D.C. Superior Court, which handles marriage licenses, said it does not track the number of same-sex marriage licenses that have been issued. But from March 3, 2010, — the day of the first same-sex marriages — through December 2010, the court received 5,828 marriage applications. During the same period in 2009, it received 2,725 applications. Freeman Klopott
