NOM has filed an amicus brief with the U.S. District Court in Massachusetts supporting the Defense of Marriage Act (you can read the entire brief below).

The basic point of the brief is that DOMA falls perfectly within America's long-standing jurisprudence tradition. The federal government has a right to define terms like "marriage" for purposes of federal law. If the federal government could not define such terms the 10th Amendment would quickly become a "reverse-supremacy" clause.
