Wedstock: On Thursday, March 11, 2004, the California Supreme Court ordered an immediate halt to marriage licenses for same-sex couples in San Francisco. Up to 600 demonstrators gathered at Market and Castro Streets at dusk for a march to Civic Center. More than 4,000 marriage licenses were issued to same-sex couples since Feb. 12. The court ruling prevents further licenses from being issued until the court hears arguments on the legality of Mayor Gavin Newsom's decision not to discriminate against gay couples. - HD
