Master The Supreme Court struck down the Communications Decency Act's criminal bans on "indecent" and "patently offensive" online communications as unconstitutional under the First Amendment. with this comprehensive case brief.
Reno v. ACLU is the Supreme Court's first major decision addressing free speech on the Internet. Decided in 1997 at the dawn of widespread public access to the Web, the case confronted whether Congress could criminalize the transmission or display of "indecent" or "patently offensive" material online in order to shield minors. The Communications Decency Act of 1996 (CDA) attempted to extend broadcast-style indecency rules to the Internet—a novel, decentralized medium that was not limited by spectrum scarcity and did not intrude upon the home in the same way broadcast signals did.
The Court held that the CDA's indecency provisions violated the First Amendment. In so doing, it rejected analogies to broadcast regulation and afforded the Internet robust constitutional protection comparable to that given to the press. Reno established the doctrinal baseline for evaluating government efforts to regulate online content: content-based criminal restrictions on protected speech face strict scrutiny and cannot be justified when less restrictive alternatives—such as user-based filters—are available.
Reno v. American Civil Liberties Union, 521 U.S. 844 (1997) (Supreme Court of the United States)
In 1996, Congress enacted the Communications Decency Act (CDA) as part of the Telecommunications Act. Two provisions were central to this case: 47 U.S.C. § 223(a)(1)(B), which made it a crime to use a telecommunications device to knowingly send to a person under 18 any "indecent" communication, and § 223(d)(1)–(2), which criminalized using an interactive computer service (including the Internet) to knowingly display or transmit any communication that, in context, "depicts or describes, in terms patently offensive" sexual or excretory activities or organs, in a manner available to minors. Violations carried criminal penalties. Although the CDA provided affirmative defenses for those who took "good faith" steps to restrict access using credit cards, adult access codes, or similar mechanisms, those measures were costly, invasive of privacy, and often unavailable to noncommercial or small speakers. A broad coalition of plaintiffs—including the ACLU, libraries, online content providers, and users—filed a facial First Amendment challenge. A three-judge district court convened under federal statute made extensive factual findings about the Internet's architecture: that users must take affirmative steps to access content; that speakers range from large publishers to individuals; and that technologies like user-end filtering and content labeling existed. The court preliminarily enjoined enforcement of the CDA's indecency provisions as likely unconstitutional. The Attorney General appealed directly to the Supreme Court.
Do the CDA's provisions criminalizing the knowing transmission or display of "indecent" or "patently offensive" online communications in a manner available to minors violate the First Amendment's protections for free speech?
Content-based restrictions on protected speech are presumptively invalid and must satisfy strict scrutiny: the government must show a compelling interest and narrow tailoring, using the least restrictive means. While the government may bar obscenity and child pornography (which are unprotected), it may not suppress indecent speech that is protected for adults simply because it is inappropriate for minors. Statutes that are vague or substantially overbroad in restricting speech are unconstitutional. Broadcast-specific rationales (such as spectrum scarcity and the medium's intrusive nature) do not justify imposing indecency rules on the Internet.
Yes. The CDA's "indecent" and "patently offensive" provisions (47 U.S.C. § 223(a)(1)(B) and § 223(d)(1)–(2)) violate the First Amendment because they are content-based, vague, and overbroad, and they are not the least restrictive means to protect minors online. The Supreme Court affirmed the preliminary injunction against their enforcement.
The Court recognized the government's compelling interest in protecting minors from harmful material. Nevertheless, the CDA failed strict scrutiny. First, the statute imposed a content-based criminal ban on a vast range of protected speech, including educational, artistic, and scientific discussions that might be considered "indecent" or "patently offensive" to some audiences. The terms "indecent" and "patently offensive" were insufficiently defined, creating substantial vagueness that would chill a broad swath of lawful speech by risk-averse speakers. Second, the CDA was overbroad because, in trying to shield minors, it effectively suppressed adult-to-adult communications: given the Internet's architecture, a speaker could rarely guarantee that only adults would access content, so lawful adult speech would be deterred or forced behind costly and impractical age-verification barriers. Third, the government failed to show narrow tailoring or that less restrictive alternatives were inadequate. The Court emphasized user-based technologies—such as filters, content labeling, and parental controls—that could block minors' access without criminalizing speech or burdening adult access. The CDA's affirmative defenses (e.g., credit card verification or adult ID systems) were not feasible for many speakers, imposed significant financial and privacy costs, and would exclude noncommercial and anonymous speakers. Finally, the Court rejected analogies to broadcast regulation (e.g., FCC v. Pacifica, Red Lion) because the Internet is not characterized by spectrum scarcity, is not invasive in the same way as over-the-air broadcasting (users must seek out content), and is more akin to the print medium, which receives the highest level of First Amendment protection. Because the CDA's means were not narrowly tailored to its concededly important ends, the provisions were unconstitutional.
Reno is the foundational case establishing that the Internet enjoys full First Amendment protection comparable to print media. It set the modern framework for evaluating government restrictions on online content: content-based criminal prohibitions on indecent speech require strict scrutiny and will fail when less restrictive, user-empowering alternatives exist. The decision also clarifies that protecting minors, while compelling, cannot justify broadly suppressing adult speech. Reno influenced subsequent cases challenging efforts to regulate online pornography and minors' access (e.g., the Child Online Protection Act litigation) and continues to shape debates over the proper roles of government regulation, parental controls, and platform policies in managing online content.
The Court rejected broadcast analogies grounded in spectrum scarcity and the medium's uniquely intrusive, pervasive nature. Internet content is accessed by user choice (not passively received), is not constrained by spectrum scarcity, and allows for targeted user-based controls. Accordingly, the Internet is more akin to print, which commands the strongest First Amendment protection, not to broadcast where indecency restrictions have sometimes been upheld.
Obscenity is categorically unprotected speech and may be criminalized for adults and minors alike under the Miller test. By contrast, "indecent" or "patently offensive" sexual speech—while potentially inappropriate for minors—remains protected for adults. The CDA targeted indecent and patently offensive content, not just obscenity, thereby restricting protected adult speech and triggering strict scrutiny.
The Court found those mechanisms burdensome, costly, and often unavailable to noncommercial or small-scale speakers; they threatened user privacy and anonymity; and they still chilled adult speech by forcing speakers to adopt complex gatekeeping measures. Because effective, less restrictive alternatives like user-end filtering existed, the CDA was not narrowly tailored.
No. The decision struck down the CDA's indecency and patently offensive provisions (47 U.S.C. § 223(a)(1)(B) and § 223(d)(1)–(2)). Other parts of the statute, including provisions unrelated to indecency and the separate Section 230 (which addresses liability for interactive computer services and users), were not before the Court and remained intact.
Reno set a high bar for content-based restrictions, leading courts to scrutinize later laws (e.g., the Child Online Protection Act) for overbreadth, vagueness, and failure to use less restrictive means. Post-Reno cases often turned on whether the government could prove that user-based filters and other noncriminal alternatives were ineffective, a showing that has been difficult to make.
Reno v. ACLU constitutionalized a vision of the Internet as a forum deserving the same robust protection as print media. By striking down the CDA's criminal indecency provisions, the Court clarified that safeguarding minors cannot be achieved by broadly criminalizing protected speech or by imposing impractical burdens on speakers.
For law students, the case is a touchstone for strict scrutiny, overbreadth, and vagueness analysis in the online context. It also frames enduring tensions in digital governance: the comparative roles of government regulation, parental empowerment through filtering technologies, and private platform policies in managing access to sensitive content while preserving adult speech.
