What article is freedom of speech in the United States?

Quick answer: which article protects freedom of speech in the United States?

Short plain-language answer: freedom of speech articles

The short answer is that the First Amendment, adopted as part of the Bill of Rights in 1791, is the constitutional provision that protects freedom of speech in the United States. National Archives transcription

Courts have long treated the First Amendment as a concise baseline text that requires interpretation by judges and lawyers, and modern legal overviews explain how that short sentence is developed through case law. Cornell LII overview

Readers should expect that the First Amendment provides broad protections but that recognized legal exceptions exist, which are defined and refined by Supreme Court precedents discussed later in this article. Brandenburg opinion summary

Why this matters for readers

Knowing which part of the Constitution protects speech helps you understand news reports, legal arguments, and policy proposals that mention free-speech limits, and our constitutional rights guide. Cornell LII overview

It also helps distinguish government action, which the First Amendment can restrict, from private moderation by platforms, which is governed by separate rules and policies. ACLU guide

What the First Amendment says and how courts use it

Exact text of the First Amendment

The operative sentence of the First Amendment states that Congress shall make no law abridging the freedom of speech, which is the core textual guarantee relied on in American free-speech law. National Archives transcription

Incorporation and judicial interpretation

The Amendment’s text is short, and courts have developed doctrines over time that explain how the wording applies to different forms of speech and different actors, as summarized in legal guides for nonlawyers. Cornell LII overview For a plain-language explainer on the amendment, see our First Amendment guide.

Through the legal doctrine known as incorporation, the Supreme Court has interpreted the First Amendment to limit state as well as federal government action, so the protection is read against a wide range of government conduct. Cornell LII overview

The basic judicial framework for evaluating speech

Content-based vs. content-neutral regulation (overview)

When courts evaluate laws that affect speech, they typically start by asking whether the law targets speech because of its content or instead regulates time, place, and manner without regard to message; legal guides summarize these approaches. Cornell LII overview

How courts balance speech and other interests

Courts treat the First Amendment as the baseline and then weigh government interests, such as public safety or privacy, against the strength of speech protections using established standards summarized in case law and overviews. Cornell LII overview

That framework means courts do not apply a single rule to all situations; rather, they ask targeted factual and legal questions about how and why speech is regulated. ACLU guide

Key Supreme Court cases that define the major limits

Brandenburg v. Ohio – incitement

The Court in Brandenburg set the modern rule that speech urging illegal action is protected unless it is directed to inciting imminent lawless action and is likely to produce such action, a high bar for limiting speech. Brandenburg opinion summary

New York Times Co. v. Sullivan – defamation and public figures

New York Times Co. v. Sullivan established the actual malice standard for defamation suits brought by public officials and public figures, meaning plaintiffs must show that false statements were made with knowledge of falsity or reckless disregard for the truth. New York Times v. Sullivan opinion

Miller v. California – obscenity

Miller created the modern three-part test for obscenity, which asks whether the material appeals to prurient interest, depicts sexual conduct in an offensive way under community standards, and lacks serious literary, artistic, political, or scientific value. Miller opinion See also a collection of Free Speech Supreme Court cases for broader context. Free Speech Supreme Court Cases

The Miller test emphasizes that local community standards can affect how obscenity is judged, so outcomes can differ by jurisdiction depending on community values and the facts at issue. Miller opinion

Recognized exceptions explained in practical terms

Incitement and the imminence/likelihood test

Incitement is limited by the Brandenburg standard, which looks for speech that is meant to produce immediate unlawful conduct and that is likely to do so; ordinary advocacy of ideas, even if unpopular, typically remains protected. Brandenburg opinion summary

True threats and public safety

Courts recognize that statements constituting true threats are not protected because they can place targets in reasonable fear and undermine public safety; legal overviews explain how threat analysis differs from political rhetoric. Cornell LII overview

Obscenity and community standards

Obscenity is defined by the Miller test, which relies on community standards and an assessment of value; material found obscene under these criteria can be lawfully regulated. Miller opinion For a legislative and research perspective on categories of speech, see the CRS summary. The First Amendment: Categories of Speech

Defamation and the actual malice standard

Defamation law allows civil liability for knowingly false statements that harm reputation, but public figures face a higher proof requirement because of the actual malice rule established by the Supreme Court. New York Times v. Sullivan opinion

Applying these doctrines to online platforms and modern contexts

How platform moderation differs from government regulation

The First Amendment restrains government actors, not private companies, so a platform removing or moderating content does not automatically trigger constitutional protection; contemporary guides explain this distinction. Cornell LII overview For an accessible federal-courts overview of what free speech means in practice, see the United States Courts educational page. What Does Free Speech Mean? Also see related coverage on freedom of expression and social media on our site.

That difference means online moderation decisions are governed by platform terms of service, contract principles, and sometimes state or federal statutes rather than by the First Amendment alone. ACLU guide

Why new laws and proposals matter but do not change the First Amendment text

Legislative proposals and administrative rules can affect how platforms operate and what speech is allowed on private services, but changing statutory rules is different from changing the constitutional guarantee in the First Amendment. Cornell LII overview

Courts continue to apply established doctrines to digital contexts, and legal commentators note that application to new technologies is an evolving area rather than a settled extension of text. ACLU guide

How courts apply tests in practice: decision criteria to watch for

Imminence and likelihood in incitement cases

Under Brandenburg, judges look for a combination of direction toward immediate unlawful action, a close temporal link between speech and likely action, and a realistic chance the speech will produce that action. Brandenburg opinion summary

Actual malice in defamation claims involving public figures

In defamation cases with public-figure plaintiffs, courts require evidence that the defendant acted with knowledge of falsity or reckless disregard for the truth, which is a demanding standard for plaintiffs to meet. New York Times v. Sullivan opinion

Community standards and the variable nature of obscenity tests

Miller asks courts to consider local community standards and whether the work as a whole has serious value, so outcomes can hinge on factual showings about content and context. Miller opinion

Common misunderstandings and typical reporting mistakes

Mistaking private moderation for constitutional restriction

A common mistake is treating a platform removing content as if the government censored it; the First Amendment restricts government action, not private companies. Cornell LII overview

Treating the First Amendment as absolute

Another mistake is presenting free speech as absolute; the Supreme Court recognizes exceptions for categories like incitement, true threats, obscenity, and defamation. Cornell LII overview

Confusing slogans and political claims with legal rules

When reading headlines or social posts, look for citations to cases or statutes rather than slogans; reliable summaries point to controlling opinions or recognized legal guides. ACLU guide

Everyday examples and short scenarios readers may encounter

Protest speech and police response

At a protest, criticizing officials is usually protected speech, but if speech is directed to immediate violence and likely to cause it, police may have lawful grounds to intervene under incitement doctrines. Brandenburg opinion summary

A social-media post flagged by a platform

If a platform removes a post, that action reflects the platform’s policies rather than a constitutional restriction; readers should check the platform’s published rules and any applicable statutes. ACLU guide

Satire, parody, and borderline obscene material

Satire and parody are typically protected, and a satirical claim about a public figure will often survive scrutiny because public-figure defamation claims require proof of actual malice and a lack of reasonable belief in truth. New York Times v. Sullivan opinion
