The U.S. Supreme Court has granted certiorari in two cases dealing with the issue of gay marriage. In United States v. Windsor, the Court will consider the constitutionality of the Federal Defense of Marriage Act. In Hollingsworth v. Perry, the Court tackles the constitutionality of California’s Proposition 8, which banned gay marriage in the State.

The Court’s action sets the stage for a highly contentious, closely watched legal battle — the first time the High Court has directly addressed the issue of gay marriage. Oral arguments are expected in March, with a decision by the beginning of summer. Future issues of Supreme Court Debates will provide full coverage.
