The U.S. Supreme Court issued two landmark rulings related to the issue of same-sex marriage Wednesday. First, the court ruled that the federal Defense of Marriage Act, which defines marriage as between a man and a woman, is unconstitutional — paving the way for legally married same-sex couples to receive the same federal benefits as straight married couples. Second, the Court dismissed an appeal against California's Proposition 8, which banned same-sex marriage in the state — meaning that same-sex marriage can resume in California.
