What is not considered free speech? A concise guide

Quick answer: an example of free speech and what is not protected

Protected speech under the First Amendment covers a wide range of expression, including political debate, artistic work, and critical commentary, even when that speech is offensive or unpopular. Courts hold that protection is broad, but they also recognize narrow categories where government may lawfully restrict expression.

An example of free speech is a political rally speech that criticizes public officials without calling for specific imminent unlawful acts. By contrast, certain narrow categories, like incitement to imminent lawless action and child sexual abuse material, are commonly treated as unprotected by U.S. law. For the incitement standard, courts apply the Brandenburg test, which requires intent and likelihood of imminent lawless action Brandenburg v. Ohio

Here is a short list of commonly unprotected categories readers will see explained below. These include incitement, true threats and fighting words, defamation with the public figure actual malice rule, obscenity under the Miller test, and child sexual abuse material treated as categorically unprotected.

International guidance frames permissible restrictions differently, asking whether limits are prescribed by law, pursue a legitimate aim, and are necessary and proportionate, which can produce different results than U.S. First Amendment doctrine Human Rights Committee General Comment No. 34

Key legal tests that define unprotected speech: clear examples and standards

1. Brandenburg test for incitement. The test requires that speech is directed to inciting imminent lawless action and is likely to produce that action. Courts use this standard to distinguish advocacy of ideas from speech that intentionally sparks immediate violence Brandenburg v. Ohio

2. Miller test for obscenity. Under the three part Miller test, material is unprotected obscenity if it appeals to prurient interest under contemporary community standards, depicts sexual conduct in a patently offensive way, and lacks serious literary, artistic, political, or scientific value Miller v. California

3. Actual malice for public figure defamation. When a public official or public figure sues for defamation, the plaintiff must prove that the defendant published a false statement with actual malice, meaning knowledge of falsity or reckless disregard for the truth New York Times Co. v. Sullivan

4. Chaplinsky and fighting words. The doctrine identifies words that by their very utterance inflict injury or tend to incite an immediate breach of the peace. Courts treat that narrow category as outside First Amendment protection when the speech is of the fighting words type Chaplinsky v. New Hampshire

5. Ferber and child sexual abuse material. The Court permits categorical prohibition of child pornography based on the state interest in protecting children, even if the material might not meet the Miller obscenity elements New York v. Ferber

How courts analyze a case: a step-by-step framework

Step 1, identify the actor and the legal setting. The First Amendment restricts government action, so the first question is whether a government actor is involved or challenged. Private platforms and private actors are not bound by the Constitution in the same way.

Step 2, characterize the speech and possible category. Courts ask whether the speech fits an established unprotected category, such as incitement, true threats, defamation, obscenity, or child sexual abuse material. If so, a specific doctrinal test will apply.

Step 3, evaluate intent and effect for incitement claims. Under Brandenburg, courts consider whether the speaker intended to produce imminent lawless action and whether the speech was likely to cause that action Brandenburg v. Ohio

Step 4, consider plaintiff status and fault for defamation. When the plaintiff is a public official or public figure, the actual malice standard governs. That raises the bar for liability by requiring proof of knowledge of falsity or reckless disregard for truth New York Times Co. v. Sullivan

Step 5, apply content and community standard tests for obscenity. If obscenity is alleged, courts use the Miller factors and ask how community standards view the material and whether it has serious value Miller v. California

Step 6, acknowledge categorical rules like Ferber. Some categories, such as child sexual abuse material, allow categorical prohibition because of the state’s interest in protecting children New York v. Ferber

Step 7, weigh context and possible competing rights. Courts examine the context to determine whether restrictions are narrowly tailored and consistent with precedent. The application often hinges on specific facts about timing, audience, medium, and content.

Key decision criteria judges rely on in contested cases

Intent and imminence. For incitement, judges look for both intent to produce imminent lawless action and a likelihood that the speech will produce that action, not merely abstract advocacy Brandenburg v. Ohio

Content and context. The same words can have different legal status depending on context. Courts consider the setting, whether the speaker targets a vulnerable audience, and whether the speech includes explicit calls for violence or illegal acts.

Plaintiff status and fault. In defamation law, whether a plaintiff is a public figure changes the burden of proof because New York Times Co. v. Sullivan requires proof of actual malice for public official or public figure plaintiffs New York Times Co. v. Sullivan

Community standards and harm to children. Obscenity analysis depends on community standards and serious value, while the interest in preventing harm to children supports categorical rules against child sexual abuse material Miller v. California

Common misunderstandings and pitfalls to avoid

Offense does not equal illegality. Material that shocks or offends most readers is often still protected speech unless it meets the narrow elements of a recognized unprotected category. Avoid assuming that offensive content is illegal without checking the applicable test Miller v. California

Private moderation versus constitutional limits. The First Amendment restricts government actors, but private platforms and publishers can remove or restrict content under their terms of service without raising constitutional issues. That difference explains why some content is removed from platforms even if the government could not lawfully ban it.

Confusing obscenity with sexually explicit material. Not all sexual content is legally obscene. The Miller test requires a three part showing, and material with serious literary, artistic, political, or scientific value will not be classified as obscene under that test Miller v. California

Be cautious with defamation claims. For public figures, the higher actual malice standard applies and makes proving defamation more difficult. Reporting should distinguish false factual claims from opinion and should check primary sources before asserting liability New York Times Co. v. Sullivan

Practical examples and short scenarios

Example 1, incitement versus protest. A speaker at a protest says vote against the mayor and criticizes policies. That is protected political advocacy in most cases. If the speaker urges the crowd to immediately attack a named individual and the speech is likely to provoke immediate violence, it can meet the Brandenburg test for unprotected incitement Brandenburg v. Ohio

Example 2, public figure libel hypothetical. A blogger publishes a false claim that a well known elected official committed a crime. The official is a public figure, so to recover damages the official must show the publisher acted with actual malice, meaning knowledge of falsity or reckless disregard for the truth New York Times Co. v. Sullivan

Example 3, obscenity and community standards. A locally produced work may be judged under community standards for prurient appeal and offensiveness. If the material also has serious literary or artistic value, it will likely avoid an obscenity finding under Miller Miller v. California

Example 4, child sexual abuse material. Any depiction of minors in sexual conduct can be treated as categorically unprotected, allowing the state greater power to prohibit and penalize distribution under Ferber New York v. Ferber

How these rules apply online and the role of platforms

Constitutional limits apply to government action, not private companies. That means social networks and hosting services can set and enforce content policies even where the government could not impose a ban under the First Amendment.

Fact patterns online raise new factual questions for courts. For example, courts consider whether speech targeted at an online audience is likely to produce imminent lawless action, and how reach or algorithmic amplification affects likelihood and imminence under Brandenburg Brandenburg v. Ohio

Platform policies, enforcement decisions, and private moderation can differ widely. That means readers should look at both the legal tests and platform rules when evaluating why content was removed or limited online.

International perspective and how human-rights guidance differs

The Human Rights Committee frames permissible restrictions with a three part test. Restrictions must be provided by law, pursue a legitimate aim, and be necessary and proportionate. That approach often leads to different balancing than U.S. constitutional doctrine Human Rights Committee General Comment No. 34

For example, a proportionality analysis under international guidance may find certain public order or hate speech limitations justified in ways that U.S. First Amendment doctrine, with its strong protection for political speech, might not permit. This is a difference of legal frameworks rather than a contradictory factual claim.

U.S. courts continue to rely on Supreme Court precedent when adjudicating constitutional questions at home, so international guidance informs debate but does not replace domestic constitutional tests like Brandenburg and Miller Brandenburg v. Ohio

Conclusion and reliable next steps for readers

In short, certain narrow categories of speech are commonly treated as unprotected in U.S. law, and the main cases to know are Brandenburg for incitement, Miller for obscenity, New York Times Co. v. Sullivan for public figure defamation, and New York v. Ferber for child sexual abuse material Brandenburg v. Ohio
