A federal judge has temporarily blocked Arkansas from enforcing a law that would have allowed criminal charges against librarians and booksellers for providing "harmful" or "obscene" materials to minors. The law, passed in April, would have allowed parents and guardians to file complaints with the Arkansas Department of Education if they believed library materials were harmful to minors. The American Civil Liberties Union of Arkansas challenged the law, arguing it was an unconstitutional infringement on free speech, and the court issued a preliminary injunction in response.
