Davis Baker, 24, center, of Phoenix, Ariz., celebrates outside the Supreme Court. The US Supreme Court has struck down a law that defines marriage as between a man and a woman only, in a landmark ruling. The court's 5-4 vote said the Defense of Marriage Act, known as Doma, denied equal protection to same-sex couples. The court also declined to rule on a California ban on same-sex marriage known as Proposition 8. The decision paves the way for gay unions there.
