First Amendment, such as printed novels or the use of the "seven dirty words", would suddenly become unlawful when posted online. Critics also claimed the bill would have a chilling effect on the availability of medical information. Online civil liberties organizations arranged protests against the bill, such as the Black World Wide Web protest, which encouraged webmasters to make their sites' backgrounds black for 48 hours after its passage, and the Electronic Frontier Foundation's Blue Ribbon Online Free Speech Campaign. Legal challenges On June 12, 1996, a panel of federal judges in Philadelphia blocked part of the CDA, saying it would infringe upon adults' free speech rights. The next month, another federal court in New York struck down the portion of the CDA intended to protect children from indecent speech as too broad. On June 26, 1997, the Supreme Court upheld the Philadelphia court's decision in Reno v. American Civil Liberties Union, stating that the indecency provisions were an unconstitutional abridgement of the First Amendment because they did not permit parents to decide for themselves what material was acceptable for their children, extended to non-commercial speech, and did not carefully define the words "indecent" and "offensive". (The Court affirmed the New York case, Reno v. Shea, the next day, without a published opinion.) In 2003, Congress amended the CDA to remove the indecency provisions struck down in Reno v. ACLU. A separate challenge to the provisions governing obscenity, known as Nitke v. Gonzales, was rejected by a federal court in New York in 2005. The Supreme Court summarily affirmed that decision in 2006. Congress has made two narrower attempts to regulate children's exposure to Internet indecency since the Supreme Court overturned the CDA. Court injunction blocked enforcement of the first, the Child Online Protection Act (COPA), almost immediately after its passage in 1998; the law was later overturned. While legal challenges also dogged COPA's successor, the Children's Internet Protection Act (CIPA) of 2000, the Supreme Court upheld it as constitutional in 2004. Section 230 Section 230 of title 47 of the U.S. Code, a codification of the Communications Act of 1934 (added by Section 9 of the Communications Decency Act / Section 509 of the Telecommunications Act of 1996) was not part of the original Senate legislation, but was added in conference with the House, where it had been separately introduced by Representatives Christopher Cox and Ron Wyden as the
