In a 1981 case called Rostker v. Goldberg, 453 U.S. 57 (1981), the U.S. Supreme Court rejected the argument that the draft is unconstitutional because only men are required by law to register. In so holding, the Court ruled that the Selective Service process is designed to enable the federal government to assemble "combat-ready" people. Because women were excluded from combat in 1981, there was no basis for requiring them to participate in the draft. As a result, the law was permissible as written. With the recent lifting of the ban on women in combat, however, the Supreme Court's rationale in Rostker v. Goldberg may no longer hold up. Sadly, the law may have to be changed to require women to register for the draft. Very sneaky Obama.
