Did both the Selective Draft Law Cases and Atkins v. Virginia find that the Constitution had been violated?
Selective Draft Law Cases Arver v. United States, 245 U.S. 366 (1918) , also known as the Selective Draft Law Cases, was a United States Supreme Court decision which upheld the Selective Service Act of 1917, and more generally, upheld conscription in the United States. The Supreme Court upheld that conscription did not violate the Thirteenth Amendment's prohibition of involuntary servitude, or the First Amendment's protection of freedom of conscience.
Overbreadth doctrine In American jurisprudence, the overbreadth doctrine is primarily concerned with facial challenges to laws under the First Amendment. American courts have recognized several exceptions to the speech protected by the First Amendment (for example, obscenity, fighting words, and libel or defamation), and states therefore have some latitude to regulate unprotected speech. A statute doing so is overly broad (hence, overbreadth) if, in proscribing "unprotected" speech, it also proscribes "protected" speech. Because an overly broad law may deter constitutionally protected speech, the overbreadth doctrine allows a party to whom the law may constitutionally be applied to challenge the statute on the ground that it violates the First Amendment rights of others. See, e.g., "Board of Trustees of State Univ. of N.Y. v. Fox", 492 U.S. 469, 483 (1989), and "R. A. V. v. City of St. Paul", 505 U.S. 377 (1992). Overbreadth is closely related to vagueness; if a prohibition is expressed in a way that is too unclear for a person to reasonably know whether or not their conduct falls within the law, then to avoid the risk of legal consequences they often stay far away from anything that could possibly fit the uncertain wording of the law. The law's effects are thereby far broader than intended or than the U.S. Constitution permits, and hence the law is overbroad.
