Summary. Every business eventually confronts a review, a post, or a statement that is false and damaging, and the instinct to sue is almost always stronger than the case. This article covers the elements of defamation, the line between fact and opinion, and the fault standards that turn on the plaintiff's status. It covers damages including the per se categories, and the adjacent torts of trade libel and tortious interference. Later sections address online speech: Section 230, unmasking anonymous speakers, anti-SLAPP statutes and fee-shifting, retraction statutes, the Consumer Review Fairness Act, and why injunctions are rarely available.

A dental practice receives a one-star review: "Worst experience of my life. Dr. Halloran is a butcher who should not be practicing. They billed my insurance for work that was never done."

The owner wants to sue. The review is on the practice's most visible listing, it has been up for three weeks, and new patient inquiries are down.

Three sentences, three different legal answers.

"Worst experience of my life" is opinion — an unverifiable expression of personal reaction. It is not actionable no matter how false the underlying feeling.

"A butcher who should not be practicing" is rhetorical hyperbole in most contexts, and courts have consistently treated colorful invective in consumer reviews as non-actionable opinion rather than a factual assertion of professional incompetence.

"They billed my insurance for work that was never done" is a verifiable factual assertion of insurance fraud. If false, it is defamatory, and it falls within the per se category of statements injuring a person in their trade or profession.

The practice has a claim on one sentence out of three — and even that claim will run into a state anti-SLAPP statute that, if the motion succeeds, will require the practice to pay the reviewer's attorney's fees.

This is the ordinary shape of business defamation. The law protects far less than businesses expect, the procedural obstacles are substantial, and the remedies that matter most are usually not legal ones.

The short answer

The elements of a defamation claim, with state variations:

  1. A false statement of fact;
  2. Of and concerning the plaintiff;
  3. Published to a third party;
  4. With the requisite degree of fault; and
  5. Causing damages (or falling into a per se category).

Libel is written or otherwise fixed; slander is spoken. The distinction matters mainly for damages.

The fault standard depends on the plaintiff:

Opinion is not actionable — but Milkovich v. Lorain Journal Co., 497 U.S. 1 (1990), rejected a separate constitutional privilege for anything labeled opinion. The test is whether the statement is provably false and whether a reasonable reader would understand it as asserting actual facts.

Truth is a complete defense, and in matters of public concern the plaintiff bears the burden of proving falsity, Philadelphia Newspapers, Inc. v. Hepps, 475 U.S. 767 (1986).

The practical warning: filing a weak defamation claim in a state with a strong anti-SLAPP statute converts a bad review into a fee award against you and a news story about the lawsuit.

The elements in detail

A statement of fact. The court asks whether the statement is provably false and how a reasonable recipient would understand it in context. Factors: the specific language used, whether the statement is verifiable, the full context of the statement, and the broader social context — a review site, an opinion column, and a heated online exchange all signal to readers that they are receiving opinion rather than reportage.

Pure opinion — a subjective evaluation not implying undisclosed facts — is not actionable. "I thought the food was terrible" is protected. Mixed opinion — an opinion implying the speaker knows undisclosed defamatory facts — can be actionable. "In my opinion, he's embezzling" implies knowledge of facts, and courts treat it as an assertion of fact wearing an opinion label.

Rhetorical hyperbole and loose figurative language are protected. Calling a negotiating position "blackmail," Greenbelt Cooperative Publishing Association v. Bresler, 398 U.S. 6 (1970), or a person a "scab" and a "traitor," Old Dominion Branch No. 496 v. Austin, 418 U.S. 264 (1974), was held non-actionable.

Falsity. The statement must be materially false. Substantial truth is a defense: minor inaccuracies do not matter if the "gist" or "sting" of the statement is true. Reporting that someone was convicted of three counts when it was two is substantially true.

Of and concerning. The statement must be reasonably understood to refer to the plaintiff. It need not name them, but group defamation claims generally fail where the group is large — a statement about "used car dealers" does not defame any particular dealer, while a statement about a four-person partnership may reach each partner.

Corporations can be defamed. A corporation has no personal reputation, but statements attacking its business integrity, credit, honesty, or the quality of its products or services are actionable.

Publication means communication to at least one third party. Republication is a separate publication, and each republisher is liable — subject to Section 230 online, discussed below. The single publication rule treats a mass communication as one publication for limitations purposes, and most states apply it to online content, so the clock runs from first posting rather than from each view. A material modification of the content can restart it.

Compelled self-publication — where a plaintiff must repeat a defamatory statement, typically to prospective employers explaining a termination — is recognized in a minority of states and rejected in most.

Fault

Public officials — government employees with substantial responsibility for governmental affairs.

All-purpose public figures — persons of such pervasive fame or notoriety that they are public figures for all purposes. A small category.

Limited purpose public figures — persons who have voluntarily injected themselves into a particular public controversy to influence its resolution. This is the contested category for businesses. Courts examine whether a public controversy existed, whether the plaintiff voluntarily assumed a prominent role in it, and whether the defamation was germane to the plaintiff's participation.

A company that advertises aggressively, engages in public advocacy, or responds publicly to criticism may find itself classified as a limited purpose public figure with respect to the controversy it engaged — which raises its burden from negligence to actual malice. Businesses considering an aggressive public response to criticism should understand that the response itself can change the standard that will apply to their own claim.

Actual malice means the defendant made the statement knowing it was false or with reckless disregard — meaning the defendant in fact entertained serious doubts as to its truth, St. Amant v. Thompson, 390 U.S. 727 (1968). It is a subjective standard about the defendant's state of mind, not a measure of care, and it is proven by clear and convincing evidence. Failure to investigate alone is generally not enough; purposeful avoidance of the truth may be, Harte-Hanks Communications, Inc. v. Connaughton, 491 U.S. 657 (1989).

Private figures must show fault, with the standard set by state law — negligence in most states, a higher standard in a few. Under Gertz, a private figure proving only negligence may recover actual damages but not presumed or punitive damages; those require actual malice. Where the speech is on a matter of purely private concern, Dun & Bradstreet, Inc. v. Greenmoss Builders, Inc., 472 U.S. 749 (1985), permits presumed and punitive damages without actual malice — which is why a false credit report circulated to five subscribers was treated differently from a public controversy.

Damages, per se categories, and privileges

Special damages are actual pecuniary loss, pleaded with specificity — lost contracts, lost customers, quantified revenue decline. They are difficult to prove, because the causal link between a statement and a business decline is contestable.

Defamation per se dispenses with proof of special damages. The traditional categories are statements imputing:

  1. A criminal offense;
  2. A loathsome disease;
  3. Unchastity (historically, and now often abolished or modernized); and
  4. Conduct incompatible with the plaintiff's business, trade, profession, or office.

The fourth category is the one businesses use. A statement that a contractor does shoddy work, that an accountant misappropriated funds, or that a restaurant served contaminated food falls within it.

Damages recoverable: harm to reputation, mental anguish (for individuals), lost profits, and the cost of corrective measures. Punitive damages require actual malice under Gertz, plus whatever the state requires. Some states cap punitive damages or require clear and convincing evidence.

Mitigation. Retraction, correction, and the plaintiff's own conduct all bear on damages, and in many states a timely retraction limits recovery by statute.

Privileges:

  • Absolute privileges — statements in judicial proceedings (including pleadings and, in most states, pre-litigation communications reasonably related to contemplated litigation), legislative proceedings, and certain executive communications. The litigation privilege is why a demand letter's allegations are generally not actionable, and why a competitor's complaint filed in court cannot be answered with a defamation counterclaim.
  • Qualified privileges — common interest communications (employer references, credit information, statements among members of an organization with a shared interest), fair report of official proceedings, and fair comment on matters of public concern. Qualified privileges are defeated by abuse — malice, excessive publication, or publication to those without the shared interest.
  • Employer references occupy a special place. Most states apply a qualified privilege, and many have enacted statutes creating a presumption of good faith for references, which is why the standard advice to give only dates and title is more conservative than the law requires.
  • Neutral reportage — a minority privilege for accurate reporting of newsworthy accusations by responsible parties — is recognized in some jurisdictions and rejected in others.

Trade libel and tortious interference

For a business, these often fit better than defamation.

Trade libel (injurious falsehood, product disparagement) targets false statements about the plaintiff's product, property, or business rather than its reputation. Elements: a false statement disparaging the plaintiff's goods, services, or business; publication to a third party; malice in the sense that the defendant intended the publication to cause pecuniary loss or reasonably should have recognized it would; and special damages — actual, quantified pecuniary loss.

The differences matter. Trade libel requires proof of special damages in every case, with no per se shortcut, and the pleading standard is demanding: identification of lost customers and transactions, not a general decline. But it reaches statements about products that defamation may not, and its fault standard can be easier in some jurisdictions.

Tortious interference with contract requires a valid contract, the defendant's knowledge of it, intentional and improper interference inducing breach, actual breach, and damages. Tortious interference with prospective economic advantage substitutes a reasonable probability of a business relationship and, in most states, requires independently wrongful conduct rather than mere competitive behavior.

Lanham Act § 43(a)(1)(B), 15 U.S.C. § 1125(a)(1)(B), is frequently the strongest claim where a competitor makes false statements in commercial advertising or promotion about its own or another's goods or services. It offers federal jurisdiction, injunctive relief, the defendant's profits, damages that may be trebled, and, in exceptional cases, fees — without the constitutional overlay that governs defamation. Lexmark International, Inc. v. Static Control Components, Inc., 572 U.S. 118 (2014), sets the standing test. A competitor's false statement about your product is usually better pleaded under the Lanham Act than as trade libel.

Other overlapping theories: false light invasion of privacy (rejected in several states); intentional infliction of emotional distress, constrained by Hustler Magazine, Inc. v. Falwell, 485 U.S. 46 (1988); state deceptive trade practices statutes, several of which expressly cover disparagement; and breach of a non-disparagement clause, which is a contract claim and avoids the constitutional framework entirely.

Section 230 and the online reality

Section 230 of the Communications Decency Act, 47 U.S.C. § 230(c)(1), provides that no provider or user of an interactive computer service shall be treated as the publisher or speaker of information provided by another information content provider.

What this means in practice:

  • Review platforms, social networks, forums, and hosts are immune from defamation liability for content posted by users. Zeran v. America Online, Inc., 129 F.3d 327 (4th Cir. 1997), established the broad reading, and it has been followed nearly universally.
  • Notice does not matter. Unlike copyright's DMCA regime, telling a platform that content is defamatory does not create liability if it declines to remove it.
  • Editorial choices are protected, including deciding what to publish, withdraw, postpone, or alter. Section 230(c)(2) separately protects good-faith restriction of objectionable material.
  • Immunity is lost where the platform is itself an information content provider — where it develops the content in whole or in part. Fair Housing Council of San Fernando Valley v. Roommates.com, LLC, 521 F.3d 1157 (9th Cir. 2008) (en banc), held that requiring users to disclose discriminatory preferences through drop-down menus made the site a content developer as to those answers.
  • Exceptions: federal criminal law, intellectual property claims, the Electronic Communications Privacy Act, and FOSTA-SESTA's sex trafficking provisions.

The consequence for a business. The platform cannot be sued. The only defendant is the person who wrote the statement — who may be anonymous, judgment-proof, or in another country. This single fact explains why most businesses' realistic options are the platform's own review policies, a public response, and reputation management rather than litigation.

Platform review policies are the practical remedy: most major review sites will remove content that violates their guidelines — conflicts of interest, reviews by competitors, reviews not based on a genuine customer experience, threats, personal attacks, and irrelevant content — and most will not remove content merely because it is negative or disputed. Learn the applicable policy and frame the request in its terms rather than in legal terms.

Anonymous speakers. Unmasking requires a subpoena to the platform or ISP, and courts apply a First Amendment balancing test before compelling disclosure. The leading frameworks are Dendrite International, Inc. v. Doe No. 3, 775 A.2d 756 (N.J. App. Div. 2001), which requires notice to the anonymous speaker with an opportunity to oppose, identification of the exact statements, a prima facie showing on each element with supporting evidence, and a balancing of the speaker's First Amendment right against the strength of the case and the need for disclosure; and Doe v. Cahill, 884 A.2d 451 (Del. 2005), which requires notification and a summary judgment standard showing.

The practical consequence: you must be able to prove your case before you learn who the defendant is. A claim that cannot survive summary judgment on the merits will not get past the unmasking stage.

Anti-SLAPP statutes

A majority of states have enacted anti-SLAPP statutes — Strategic Lawsuits Against Public Participation — and they have transformed defamation practice.

The typical mechanism. A defendant sued for statements made in connection with an issue of public interest or in a protected forum files a special motion to strike or to dismiss, usually within a short window after service. The burden then shifts to the plaintiff to establish a probability of prevailing on the merits, supported by admissible evidence. Discovery is stayed while the motion is pending, subject to limited exceptions. If the motion is granted, the defendant is entitled to mandatory attorney's fees, and an interlocutory appeal is often available as of right.

Scope varies enormously. California's statute, Cal. Civ. Proc. Code § 425.16, is among the broadest and reaches statements in a public forum on an issue of public interest — which courts have applied to consumer reviews. Texas's Citizens Participation Act was broad and was narrowed by amendment. Other states limit the statute to petitioning activity, or to specific subject areas, and roughly a dozen have no anti-SLAPP statute at all. The Uniform Public Expression Protection Act has been adopted in a growing number of states and provides a consistent framework.

Whether state anti-SLAPP statutes apply in federal court has divided the circuits, with several holding the special motion procedure inapplicable as inconsistent with Rules 12 and 56, and others applying it. There is no federal anti-SLAPP statute.

The practical effect. In a state with a broad statute, a business suing over a consumer review faces a motion that stays discovery, requires it to prove its case on paper within weeks, and — if it loses — awards the defendant's fees. Before filing, counsel should determine whether an anti-SLAPP statute applies, whether it reaches the speech at issue, and whether the plaintiff can meet the burden with admissible evidence available now.

Retraction statutes, the Consumer Review Fairness Act, and remedies

Retraction statutes exist in most states. They typically require a plaintiff to demand a correction or retraction within a defined period as a precondition to recovering certain damages — often punitive damages, and in some states general damages as well. Some apply only to media defendants; others reach all defendants. A plaintiff who sues without sending the demand can forfeit the damages that made the case worth bringing.

The Consumer Review Fairness Act, 15 U.S.C. § 45b, voids form contract provisions that restrict a consumer's ability to review a company's goods, services, or conduct; impose penalties for doing so; or require the consumer to transfer intellectual property rights in the review. It authorizes FTC and state attorney general enforcement. The Act does not protect false statements, defamation, trade secret disclosure, or content unrelated to the consumer's own experience — but the practical effect is that non-disparagement clauses in consumer form contracts are unenforceable and unlawful, and businesses still using them face enforcement risk on top of an unenforceable term.

Note the distinction: non-disparagement clauses in negotiated agreements between businesses, or in employment separation agreements, are outside the Act — though separation agreement non-disparagement clauses face their own constraints under labor law and under state statutes restricting confidentiality of harassment and discrimination claims.

Injunctive relief is the remedy businesses want and rarely get. The traditional rule is that equity will not enjoin a libel, and a pre-publication injunction is a prior restraint bearing a heavy presumption against constitutional validity, Near v. Minnesota, 283 U.S. 697 (1931). A growing number of courts will enter a narrow permanent injunction after a final adjudication that specific statements are false and defamatory — ordering removal of those statements and prohibiting their repetition — but the relief is post-judgment, narrow, and unavailable at the outset.

Enforcement problems compound the difficulty. A judgment against an anonymous or judgment-proof defendant produces nothing, and foreign defendants may be beyond practical reach — though the SPEECH Act, 28 U.S.C. §§ 4101-4105, works in the other direction, barring US recognition of foreign defamation judgments that do not satisfy First Amendment standards.

The response playbook

For most businesses, the legal analysis is the beginning of the decision, not the end. A structured response:

Hour 1 — Assess, do not react.

  • Screenshot and preserve the statement with metadata, URL, date, and author information.
  • Determine whether it is fact or opinion, sentence by sentence.
  • Determine whether it is true. This is uncomfortable and essential; a substantially true statement ends the analysis.
  • Identify the author if known, and any relationship — customer, former employee, competitor.

Day 1 — Consider the non-legal remedies first.

  • Respond publicly, once, briefly, professionally, and without disclosing confidential or health information. A calm response that offers to resolve the issue offline is read by every future reader and is worth more than the review's removal.
  • Do not argue, do not accuse the reviewer of lying, and do not reveal customer details — several enforcement actions and licensing complaints have arisen from healthcare providers responding to reviews with patient information.
  • Report the content to the platform under its policies if it genuinely violates them.
  • Ask satisfied customers to review, without incentivizing, which is itself an FTC issue.

Week 1 — Evaluate the claim.

  • Which statements are provably false factual assertions?
  • What is the plaintiff's status — private figure, or arguably a limited purpose public figure?
  • Can damages be proven with specificity?
  • Does an anti-SLAPP statute apply, and can the burden be met on paper?
  • Is a retraction demand required by statute before suing?
  • Is the defendant identifiable, solvent, and within reach?
  • Is there a better claim — Lanham Act against a competitor, breach of a negotiated non-disparagement clause, or tortious interference?

The cease and desist decision. A demand letter can work — particularly against an identified person who overstated a real grievance. It can also produce the Streisand effect, in which the letter itself becomes the story and the statement reaches an audience it never had. Send it only where the recipient is likely to comply, where the statement is unambiguously false and factual, and where the business is prepared for the letter to be published.

When litigation is right. A competitor making false factual claims in the market; a former employee or contractor circulating fabricated allegations to customers; a coordinated campaign; or a statement so specific and damaging that the business cannot function without a judicial declaration of falsity. In those cases the claim is usually strong, the defendant is identifiable and solvent, and the anti-SLAPP analysis is manageable because the speech is commercial rather than a consumer's account of their own experience.

A worked example

Harrow Industrial Coatings learns that a competitor's sales representative has told at least four shared customers that Harrow "lost its ISO certification last year" and that "their product failed the state DOT durability test." Both statements are false; Harrow's certification is current and its product passed.

Analysis.

  • Both are verifiable factual assertions, not opinion.
  • Both are false.
  • Both were made in commercial advertising or promotion by a competitor about Harrow's goods.
  • Harrow is a private figure, and the statements concern a private commercial matter rather than a public controversy — which, under Dun & Bradstreet, eases the damages analysis.

Claim selection. The strongest claim is Lanham Act § 43(a)(1)(B): federal jurisdiction, no constitutional fault overlay, injunctive relief available, and the possibility of the defendant's profits and treble damages. Harrow adds state-law trade libel and tortious interference with prospective advantage, and defamation per se.

Anti-SLAPP. The statements are commercial speech to customers, not statements in a public forum on an issue of public interest. The state's statute contains a commercial speech exemption, and the motion fails.

Evidence. Declarations from the four customers; the sales representative's emails obtained in discovery; the current ISO certificate; and the DOT test results. Damages are proven through two lost contracts with identifiable value plus expert testimony on price erosion.

Outcome. Preliminary injunction prohibiting repetition, a corrective letter to the affected customers, and a settlement including damages and a permanent injunction.

Contrast with the dental practice. Same body of law, opposite result — because the speaker was a consumer describing their own experience in a public forum, most of the statement was opinion, and the anti-SLAPP statute applied squarely. The distinguishing facts are who spoke, in what capacity, and whether the statement is verifiable.

Frequently asked questions

Can we sue over a bad review? Only over provably false factual assertions. Opinions, ratings, and hyperbole are not actionable, and an anti-SLAPP statute may award the reviewer's fees against you.

Can we make the platform take it down? Not through litigation — Section 230 immunizes it. Through its own content policies, sometimes.

The review is anonymous. Can we find out who wrote it? Only by subpoena, subject to a First Amendment balancing test that generally requires notice to the speaker and a prima facie showing on every element before disclosure is compelled.

Can we require customers to sign a non-disparagement clause? No. The Consumer Review Fairness Act voids such provisions in consumer form contracts and authorizes enforcement.

A former employee is telling customers we are being investigated. What can we do? If false and factual, this is defamation per se and likely tortious interference. Check the separation agreement for a non-disparagement clause, which converts it into a contract claim.

Is truth always a defense? Yes to defamation. Substantial truth suffices. But a true statement can still support other claims — breach of a confidentiality obligation, trade secret misappropriation, or invasion of privacy.

Should we respond publicly? Usually yes — once, briefly, professionally, and without confidential details. The response is for future readers, not for the reviewer.

Can we get an injunction ordering the post removed? Rarely before judgment; prior restraint doctrine bars it. Some courts will enter a narrow injunction after a final determination that specific statements are false.

Conclusion

Defamation law protects reputation against false facts, and almost nothing else. It does not protect against unfairness, exaggeration, incomplete accounts, or opinions that are wrong. The gap between what feels defamatory and what is actionable is where most businesses lose money on lawyers.

Three questions resolve most situations. Is the statement a verifiable assertion of fact? Is it false? And is there a defendant who can be identified, reached, and made to pay?

When all three answers are yes — usually a competitor's false claims, or a former insider's fabrications circulated to customers — the case is worth bringing, and the Lanham Act is often the better vehicle. When any answer is no, the productive response is a short public reply, a platform report, and a service recovery, which is faster, cheaper, and read by everyone the lawsuit would never reach.

Insurance, and who pays for the defense

Defamation is one of the few torts that ordinary business insurance was designed to cover, and companies on both sides of these disputes routinely fail to notice.

Commercial general liability policies include Coverage B — Personal and Advertising Injury, which in the standard ISO form defines the covered offenses to include oral or written publication, in any manner, of material that slanders or libels a person or organization or disparages a person's or organization's goods, products, or services, along with publication that violates a person's right of privacy, use of another's advertising idea, and infringement of copyright, trade dress, or slogan in an advertisement.

What this means practically:

  • A business sued for defamation, disparagement, or invasion of privacy usually has a defense under its CGL policy, and the duty to defend is broader than the duty to indemnify — triggered if any allegation is potentially covered.
  • The tender must be made promptly and in writing. Companies handle a defamation suit as a reputational matter and forget the insurance entirely, absorbing defense costs they never had to pay.

The exclusions that matter in Coverage B:

  • Knowing violation of rights of another — material published with knowledge of its falsity. This exclusion tracks the actual malice standard, which is why coverage frequently exists for a negligent defamation claim and disappears if the plaintiff proves knowledge.
  • Material published prior to the policy period.
  • Breach of contract, which excludes a non-disparagement clause claim.
  • Quality or performance of goods — failure to conform to statements, which excludes claims arising from the insured's own advertising of its products.
  • Wrong description of prices.
  • Infringement of copyright, patent, trademark, or trade secret, other than in the insured's advertisement.
  • Insureds in media and internet-type businesses — a broad exclusion for publishers, broadcasters, and content providers, which is why a media business needs a media liability policy rather than relying on CGL.

Media and technology liability policies provide broader coverage designed for content risk, including defamation, privacy, IP in content, and errors in published material, usually on a claims-made basis with a retroactive date.

Employment practices liability may respond to defamation claims arising from employment — a false statement in a reference, or an accusation made in a termination — which is a common and often-overlooked source of coverage.

Directors and officers coverage may respond where an individual executive is named.

The counsel question. Because the carrier owes a defense, it usually appoints panel counsel. Where the coverage position turns on facts that the defense will develop — whether the statement was published knowingly, for instance — a genuine conflict may entitle the insured to independent counsel at the carrier's expense. Raise it early, in writing, rather than after the defense is underway.

On the plaintiff's side, the insurance analysis is a collectability analysis. A defendant with CGL coverage can pay a settlement that an individual could not, which changes the calculus about whether the case is worth bringing and against whom.
