President Obama’s Justice Department filed legal papers late Thursday to dismiss the first same sex marriage case filed in federal court. The Justice Department defended the Defense Of Marriage Act, or DOMA, which as a candidate then-Sen. Obama opposed, saying that the plaintiffs Arthur Smelt and Christopher Hammer are seeking a ruling on “whether by virtue of their marital status they are constitutionally entitled to acknowledgment of their union by states that do not recognize same-sex marriage, and whether they are similarly entitled to certain federal benefits. Under the law binding on this Court, the answer to these questions must be no.”
