  skos:definition "The Supreme Court decision in Lamont v. Postmaster General , 381 U.S. 301 (1965), invalidated a statute allowing the Postmaster General to regulate the flow of “communist political propaganda” through the mails. Lamont was the first time the Supreme Court invalidated a federal statute under the speech and press clauses of the First Amendment, the first case to hold that the First Amendment includes a “right to receive,” and the first time a justice used the phrase “marketplace of ideas” in a judicial opinion.
