A federal judge has ruled that a men-only draft is unconstitutional, but he stopped short of ordering the Selective Service System to register women for military service. The Houston judge sided with a San Diego men's advocacy group that challenged the government's practice of having only men sign up for the draft, citing sex discrimination in violation of the Fifth Amendment's equal protection clause. The ruling does not order the federal government to change its policy on who must register, nor does it make any recommendation to Congress, which would have to change the laws governing the Selective Service System to require women to sign up.
