A schedule could be established on Monday for federal litigation challenging the Defense of Marriage Act during a status conference before a New York federal district court.

The status conference concerns the case of Windsor v. United States, which was filed by the American Civil Liberties Union, and will take place before Magistrate Judge James Francis at the Southern District of New York Courthouse. The lawsuit contends that DOMA is unconstitutional because it violates the equal protection principles of the Fifth Amendment.

Robyn Shepard, an ACLU spokesperson, said the judge will hear proposals from the parties about the schedule for briefing and discovery for the case, and he may decide on a schedule.
