A statement is defamatory when it is a false factual claim about an identifiable person, communicated to someone other than the subject, that damages the subject’s reputation. Defamation is a civil wrong, not a crime, which means the person harmed can sue for money damages. Written or otherwise fixed statements are called libel; spoken or transitory ones are called slander. The rules below decide who wins.
The Four Elements a Plaintiff Must Prove
Courts across the country follow the framework set out in the Restatement (Second) of Torts § 558, with minor variations by state.1Yale Law Tech. Restatement (2d) of Torts and 47 U.S.C. 230 A defamation claim fails unless each of the following is present:
- A false statement of fact about the plaintiff. Truth is a complete defense, no matter how damaging the true statement is. The statement must also be “of and concerning” the plaintiff — a reasonable listener or reader has to be able to tell who is being discussed, even without a name.
- Publication to a third party. The statement has to reach at least one person other than the subject. A nasty letter sent only to the person it is about does not count. Telling a single coworker is enough.
- Fault by the speaker. At a minimum, the speaker must have been negligent about whether the statement was true. For public officials and public figures the bar is higher, as discussed below.
- Harm to the plaintiff. Either real injury to reputation (lost job, dropped clients, documented emotional distress) or an injury the law presumes from the nature of the statement itself.
Groups generally cannot sue unless the group is small enough that the statement effectively targets each member. “All lawyers are crooks” supports no claim. “Both partners at Smith and Jones are crooks” probably does.
Libel vs. Slander
Libel covers statements fixed in a permanent medium: newspaper articles, blog posts, social media updates, emails, captioned photographs. Slander covers spoken or transitory statements. The split matters most when proving damages. Libel plaintiffs in most jurisdictions do not need to prove specific financial losses, because permanence creates a presumption of harm. Slander plaintiffs generally must document actual economic loss unless the statement falls into one of the “per se” categories.
Technology blurs the line. A recorded voicemail is treated as libel by some courts. A live broadcast might be slander in one state and libel in another. The underlying question is whether the statement was preserved in a way that lets harm keep spreading.
Defamation Per Se
Four categories of false statements are treated as so inherently damaging that courts presume harm without the plaintiff proving specific losses:
- Accusing someone of a serious crime, such as robbery or fraud.
- Attacking professional competence, such as calling a doctor incompetent or saying an accountant embezzles.
- Claiming someone has a loathsome disease, historically covering sexually transmitted infections and other heavily stigmatized conditions.
- Imputing serious sexual misconduct, such as a false adultery accusation.
Inside these categories, a jury can award damages based on the nature of the accusation alone. Outside them, a slander plaintiff who cannot show concrete financial loss may walk away with nothing even when the statement was plainly false.
Fact vs. Opinion
Only statements that can be proven true or false qualify as defamatory. Pure opinion is protected by the First Amendment because a subjective belief cannot be objectively verified. Saying a restaurant has “terrible food” is opinion. Saying it “failed its last health inspection” is factual, and if false, it is actionable.
The trap is opinion that implies hidden facts. “I believe he’s stealing from the company, based on what I saw Friday night” is not shielded by the words “I believe.” A reasonable listener hears a claim about observed theft. Courts look at how the audience would interpret the statement in context, not at the speaker’s choice to frame it as belief. You cannot launder a factual accusation through the phrase “I think.”
Public Figures Face a Much Higher Burden
The fault a plaintiff must prove depends on who the plaintiff is. This is one of the most consequential lines in defamation law.
Public Officials and Public Figures
In New York Times Co. v. Sullivan (1964), the Supreme Court held that public officials suing for defamation must prove “actual malice” — meaning the defendant either knew the statement was false or acted with reckless disregard for whether it was true.2United States Courts. New York Times v. Sullivan The Court later extended the same standard to public figures generally. The reasoning is that public figures have platforms to answer false statements, so the law gives speakers more room to be wrong about them.3Justia. New York Times Co. v. Sullivan
Actual malice is genuinely hard to prove. A journalist who gets a story wrong after reasonable research is not liable even if the error was damaging. The plaintiff must show the defendant subjectively doubted the truth and published anyway, or knew the statement was false outright. Sloppy work alone is not enough.
Limited-Purpose Public Figures
Some otherwise private people become public figures only for a particular controversy by voluntarily entering a public debate. The Supreme Court recognized this category in Gertz v. Robert Welch, Inc. (1974). A small business owner who launches a public campaign against a local policy might become a limited-purpose public figure on that topic. Actual malice would apply to statements about the campaign, but not to unrelated false claims about the owner’s personal life.
Private Individuals
Under Gertz, states can let private-figure plaintiffs recover by proving the defendant was merely negligent — that is, failed to use reasonable care in checking the statement.1Yale Law Tech. Restatement (2d) of Torts and 47 U.S.C. 230 Most states have adopted negligence as the private-figure standard. Private people did not sign up for public life and typically have no comparable platform to correct a false narrative.
Defenses Beyond Truth
Truth defeats any defamation claim. Two kinds of privilege also protect speakers in specific settings.
Absolute privilege applies when the setting matters more than the risk of abuse. Statements made during judicial proceedings by judges, attorneys, parties, and witnesses are absolutely privileged as long as they have some connection to the case. The same goes for statements in legislative proceedings and certain official communications by government officials acting within their duties. A witness who makes a deliberately false accusation under oath cannot be sued for defamation over that testimony.
Qualified privilege protects good-faith statements where the speaker and listener share a legitimate interest in the information. The classic example is a job reference: a former employer who honestly shares concerns about a past employee is protected even if some concerns prove inaccurate. The privilege is lost if the speaker acted with actual malice. News reporting on matters of public concern enjoys qualified privilege in many jurisdictions, particularly for live events where there is no time to verify.
Online Defamation and Section 230
A false statement posted to social media can reach thousands of people in hours, and because the content is written and persistent, most online defamation is libel rather than slander. The hard question is who to sue.
Under 47 U.S.C. § 230(c)(1), no provider or user of an interactive computer service can be treated as the publisher of content created by someone else.4Office of the Law Revision Counsel. 47 USC 230 – Protection for Private Blocking and Screening of Offensive Material If someone posts a defamatory review on Yelp or a false accusation on Facebook, you generally cannot sue the platform. Your claim lies against the person who wrote it. Section 230 immunity applies even where the platform was notified and refused to take the content down.
Section 230 does not protect the person who created the defamatory content. And under the republication rule, anyone who shares, reposts, or forwards a defamatory statement faces the same potential liability as the original speaker. “Someone else said it first” is not a defense.
What a Win Is Worth
Damages fall into three categories, with availability depending on the facts and the jurisdiction.
- Special damages — documented economic losses such as lost business revenue, a terminated contract, or reduced earning capacity. These require receipts, financial records, or similar proof.
- General damages — non-economic harm such as emotional distress, humiliation, and reputational injury itself. Harder to quantify, and not available in every case, particularly slander claims outside the per se categories.
- Punitive damages — awards meant to punish egregious conduct and deter repeats. These typically require proof of actual malice or willful disregard for the truth. Under Gertz, private-figure plaintiffs who prove only negligence are limited to actual injury and cannot recover punitives.
Awards range from nominal sums to multimillion-dollar verdicts. A false accusation that costs someone a career supports far larger damages than one that caused temporary embarrassment and nothing else.
The Deadline to File Is Short
Most states set the statute of limitations for defamation at one or two years from publication, with a handful allowing up to three. These windows are shorter than for most other civil claims because the system wants reputation disputes resolved while evidence is fresh. Miss the deadline and the claim is almost always dead, no matter how strong it was.
For online content, the clock usually starts when the statement is first published, not when the subject discovers it. A defamatory post that sits unnoticed for two years may already be out of time by the time the subject learns about it. A few jurisdictions apply a “discovery rule” that starts the clock when the plaintiff knew or should have known about the statement, but that is the exception.
If You Are the One Being Sued: Anti-SLAPP
Not every defamation suit is filed in good faith. Some exist to silence critics. These are known as SLAPP suits (Strategic Lawsuits Against Public Participation), and roughly 40 states plus the District of Columbia have anti-SLAPP statutes. Anti-SLAPP laws let a defendant file an early motion to dismiss a meritless claim before expensive discovery begins. If the court grants the motion, the plaintiff can be ordered to pay the defendant’s attorney fees and costs. Some states authorize additional sanctions. Coverage varies: some statutes protect only speech about government affairs, others cover any speech on a matter of public concern, and a few states have no anti-SLAPP law at all.
