Few topics on the MBE trip up test-takers more reliably than the regulation of unprotected speech. You know the First Amendment protects speech — but then you see an answer choice that says “the government can regulate this,” and suddenly you’re second-guessing everything you thought you knew.

Here’s the thing: the First Amendment doesn’t protect all speech equally. Certain narrow categories of speech fall outside constitutional protection entirely, meaning the government can regulate or prohibit them without satisfying strict scrutiny. Knowing exactly what those categories are — and what elements define each one — is the difference between a right answer and a wrong one on the MBE.

What “Unprotected Speech” Actually Means

When we say speech is unprotected, we mean the government has a compelling enough interest in suppressing it that the normal First Amendment balancing never even kicks in. The Supreme Court has identified specific categories of speech that, by their nature, are of such low social value that regulating them is constitutionally permissible.

This doesn’t mean the government has a blank check. Even within unprotected categories, the regulation has to target the right thing. A law that’s overbroad — one that sweeps in protected speech while trying to reach unprotected speech — is still unconstitutional. Keep that in mind as you work through each category below.

The Categories of Unprotected Speech You Need to Know

1. Incitement

Under the test established in Brandenburg v. Ohio, speech can be regulated as incitement only if it meets three specific elements. The speech must be (1) directed to inciting or producing imminent lawless action, (2) likely to produce such action, and (3) intended to cause that imminent lawless action.

All three elements must be present. This is a tight standard. Abstract advocacy of illegal conduct — even violent illegal conduct — is protected. What’s not protected is speech that functions as a call to arms in the immediate moment.

MBE-style example: A speaker at a rally shouts, “We need to burn down City Hall someday to send a message to these politicians.” That’s probably protected. But if the speaker shouts, “Burn it down — right now — let’s go!” while the crowd is already moving toward City Hall, you’re looking at incitement. The imminence element is doing a lot of work here.

2. True Threats

True threats are statements where the speaker communicates a serious expression of intent to commit unlawful violence against a specific person or group. The government can regulate true threats even if the speaker claims they didn’t actually intend to carry them out.

The key distinction is between a genuine threat and hyperbole, political rhetoric, or artistic expression. Courts look at whether a reasonable person would interpret the communication as a serious threat. After Counterman v. Colorado (2023), the Court clarified that some level of subjective awareness by the speaker — at minimum recklessness — is required. Watch for this on newer MBE questions.

3. Fighting Words

Fighting words are face-to-face personal insults directed at a specific individual that are likely to provoke an immediate violent reaction from the ordinary person. The doctrine comes from Chaplinsky v. New Hampshire.

This category has been significantly narrowed over time. The Court has been reluctant to uphold fighting words regulations in practice, often finding them overbroad or content-based in a discriminatory way. For MBE purposes, know the definition — but also know that laws targeting fighting words frequently fail on other grounds.

4. Obscenity

Obscenity is unprotected under the three-part Miller v. California test. Material is obscene if (1) the average person, applying contemporary community standards, would find that the work, taken as a whole, appeals to the prurient interest; (2) the work depicts or describes sexual conduct in a patently offensive way as defined by applicable state law; and (3) the work, taken as a whole, lacks serious literary, artistic, political, or scientific value — the so-called SLAPS test for the third prong.

All three prongs must be satisfied. Note that the third prong — serious value — is judged by a national reasonable person standard, not community standards. That asymmetry has shown up on the MBE before.

Child pornography is a separate category. It’s unprotected even if it doesn’t meet the Miller test, because the government’s interest in protecting children from exploitation is independent of whether the material is obscene.

5. Defamation

Defamation is a false statement of fact that damages someone’s reputation. It’s unprotected, but the level of constitutional protection the plaintiff must overcome depends heavily on who is being defamed.

If the plaintiff is a public figure or public official, they must prove the defendant acted with actual malice — knowledge that the statement was false or reckless disregard for its truth or falsity (New York Times v. Sullivan). If the plaintiff is a private figure and the matter is of public concern, states may set their own standard but cannot impose strict liability. If the matter is purely private, states have more flexibility.

This is a heavily tested area. The MBE loves to test whether you can correctly classify the plaintiff and apply the right standard.

6. Fraud and Misrepresentation

Speech that is intentionally false and used to deceive — fraud, perjury, false statements in commercial contexts — is generally unprotected. The government’s interest in regulating deceptive conduct is strong enough to override First Amendment concerns.

7. Speech Integral to Criminal Conduct

Speech that is itself part of criminal activity — solicitation, conspiracy, bribery — is unprotected. The First Amendment doesn’t become a shield just because the criminal conduct happened to involve words.

The Overbreadth and Vagueness Traps

Even when the government is targeting a legitimate unprotected category, a law can still be struck down if it’s overbroad or vague.

An overbroad law is one that prohibits substantially more speech than the unprotected category justifies — it reaches protected speech in the process of trying to reach unprotected speech. A vague law fails to give people fair notice of what conduct is prohibited, which creates a chilling effect on protected expression.

Both doctrines are tested on the MBE, often as the correct answer when a law targeting unprotected speech is still struck down. If a statute is facially overbroad, a defendant can challenge it even if their own conduct was actually unprotected.

Content-Based vs. Content-Neutral Regulations of Unprotected Speech

Here’s a subtle point that shows up in harder MBE questions. Even within unprotected categories, the government cannot regulate selectively based on viewpoint. If a state says, “fighting words directed at the government are prohibited, but fighting words directed at private citizens are fine,” that’s a viewpoint-based distinction — and it’s unconstitutional even though fighting words themselves are unprotected (R.A.V. v. City of St. Paul).

The rule: you can ban an entire unprotected category. You cannot ban only the parts of that category you disagree with ideologically.

FlashTables and the Regulation of Unprotected Speech

FlashTables is a set of professionally formatted two-column PDF rule tables covering all seven MBE subjects — 704 rules total, organized by the official NCBE Subject Matter Outline. The rules on unprotected speech categories, including the Brandenburg incitement test, the Miller obscenity standard, and the defamation framework, are laid out side-by-side in the Constitutional Law table, making it easy to drill each element in sequence. Whether you’re a law student locking in black-letter law for your Con Law final or a bar-taker doing rapid active recall in the final weeks before the MBE, having these rules in a clean, scannable format at getflashtables.com means you’re not hunting through outlines when you should be drilling.
