When a former employee, a competitor, or an anonymous reviewer publishes a false statement that costs your company customers, Minnesota law gives you a way to respond. A business can sue for defamation, and the claim has four defined elements you must prove. Defamation itself is a Minnesota common-law tort, shaped by the courts rather than a single statute, but two pieces of Minnesota statutory law sit alongside it: the Minnesota Uniform Deceptive Trade Practices Act, Minn. Stat. § 325D.44, which gives you a parallel claim for disparagement of your goods or services, and the Uniform Public Expression Protection Act, enacted in 2024, which now governs how a suit over public-facing speech proceeds. In my practice advising Minnesota business owners, the recurring question is not whether a false statement is hurtful, it is whether it is legally actionable, and the two are not the same. This article walks through what a Minnesota business has to prove, what it can recover, and where a defamation suit can go wrong. For broader context, see our Minnesota business torts practice area.
What must a Minnesota business prove to win a defamation claim?
To win a defamation claim in Minnesota, a business must prove four elements: a false statement, communication of that statement to someone other than the business, harm to the business’s reputation, and that the statement reasonably refers to that specific business. The Minnesota Supreme Court has stated that a plaintiff must prove the statement “was ‘communicated to someone other than the plaintiff’”; that “the statement is false”; that it “tends to ‘harm the plaintiff’s reputation and to lower [the plaintiff] in the estimation of the community’”; and that “’the recipient of the false statement reasonably understands it to refer to a specific individual.’” (McKee v. Laurion, 825 N.W.2d 725, 730 (Minn. 2013).)
Each element does real work. A statement made only to you, with no third person hearing or reading it, is not actionable because nothing was communicated to anyone else. A statement that names no one and could refer to any of a dozen companies may fail the identification element. The most contested element in the disputes I see is falsity, because the speaker almost always argues the statement was true or was just an opinion. The identification element matters more than business owners expect: a vague online complaint about “a contractor in the area” may not be actionable, while a review naming your company is. Who said it also affects the analysis, because a statement repeated by an employee can expose both the employee and the company, a point covered in our discussion of who can be liable when an employee makes a defamatory statement.
What is the difference between libel, slander, and trade libel?
Libel and slander are two forms of the same defamation tort, separated by how the statement was published: libel is a defamatory statement in a fixed form, such as writing, an online review, or a social media post, while slander is a spoken defamatory statement. Trade libel, also called product disparagement, is a separate claim. Instead of attacking the honesty or character of a business, it attacks the quality of the business’s goods or services with a false factual claim.
The practical line is what the statement is about. A false claim that your company cheats its customers is classic defamation. A false claim that your product is defective or contaminated is trade libel. Minnesota gives trade libel a statutory home in the deceptive-trade-practices law. A person commits a deceptive trade practice when, in the course of business, the person “disparages the goods, services, or business of another by false or misleading representation of fact.” (Minn. Stat. § 325D.44, subd. 1.) A common-law trade-libel claim has generally carried a heavier burden than ordinary defamation: Minnesota’s approach has been to require the plaintiff to prove special damages, meaning specific lost sales or lost contracts traceable to the false statement. The statutory route under the deceptive-trade-practices law can be easier, as the next sections explain. These distinctions come up most often in competitor disputes, addressed further in our articles on defamation claims arising from competitor product comparisons and on commercial and product disparagement under Minnesota law and the Lanham Act. For the libel-versus-slander line in non-business contexts, see our overview of the distinction between libel and slander in Minnesota.
What counts as a false statement of fact instead of protected opinion?
Only a false statement of fact can support a defamation claim. Truth is a complete defense, and a statement that conveys a subjective opinion rather than a verifiable fact is not actionable at all. The Minnesota Supreme Court has put the truth rule plainly: “Truth is a complete defense to a defamation action and ’true statements, however disparaging, are not actionable.’” (McKee v. Laurion, 825 N.W.2d 725, 730 (Minn. 2013).) The Court added that “if the statement is true in substance, minor inaccuracies of expression or detail are immaterial.”
This is where many business defamation claims fail before they reach a jury. A review saying “the worst service I have ever received” is an opinion, not a provable fact, and a court will treat it as protected. A review saying “this company billed me for parts it never installed” is a factual claim that is either true or false, and it is actionable if false. The harder cases sit in between, where a statement implies a fact without stating it outright. The line a court draws turns on whether the statement can reasonably be read as asserting an objectively verifiable fact rather than a subjective view. Before sending a demand letter over a negative review, I read each sentence and sort it into fact or opinion, because the opinion sentences carry no claim and threatening suit over them weakens your position.
What is defamation per se, and when are damages presumed?
Defamation per se is a category of statements so obviously damaging that Minnesota law may presume harm without the plaintiff proving specific dollar losses. A false statement that a business or its owner engaged in improper or incompetent conduct in their trade or business falls within this category, as do false accusations of serious crime. Minnesota recognizes that presumed damages may be available when a plaintiff establishes that the challenged statements are defamatory per se. (Maethner v. Someplace Safe, Inc., 929 N.W.2d 868 (Minn. 2019).)
For a business, the per se category matters because reputational damage is real but hard to quantify. If a false statement says your company committed fraud, you should not have to produce a spreadsheet of lost customers to recover something. That is the function of presumed damages. The category is not unlimited, though. It reaches statements about the business’s competence, integrity, or criminal conduct, not every unflattering remark. And the presumed-damages rule carries a major constitutional limit when the statement touches a matter of public concern, which the next section explains. The interaction between per se status and the public-concern limit is the part of Minnesota defamation law that most often surprises business owners.
How does the public-concern rule limit damages in a business defamation case?
When a defamatory statement involves a matter of public concern, a private-figure plaintiff cannot recover presumed damages without proving actual malice. Most businesses are private-figure plaintiffs, so this rule applies to them directly. Under Minnesota law, a private plaintiff cannot recover presumed damages for statements on a matter of public concern without proving actual malice. (Maethner v. Someplace Safe, Inc., 929 N.W.2d 868 (Minn. 2019).) Actual malice means the statement was made with knowledge that it was false or with reckless disregard of whether it was false.
This limit has teeth in the online-review setting. A public-facing review of a business’s services can be treated as speech on a matter of public concern, because consumers reading reviews is the kind of public discussion the First Amendment protects. If a court reaches that conclusion, your business cannot rely on presumed damages. You must either prove actual harm to reputation with evidence or prove the reviewer knew the statement was false or recklessly disregarded its truth. Actual malice is a demanding standard, and proving what a reviewer actually knew is difficult. In my experience, this is the single most important reason a business defamation claim that looks strong at first becomes hard to win: the statement is false, but the damages theory collapses under the public-concern rule. Reviews posted on social media raise the same issue, discussed in our article on social media posts that create defamation exposure.
What privileges protect a person who made the statement?
Even a false and damaging statement may not be actionable if the speaker has a privilege. Minnesota recognizes absolute privileges and qualified privileges, and a privilege is a complete or partial defense depending on which one applies. An absolute privilege protects statements made in certain settings, such as testimony in a judicial proceeding, regardless of the speaker’s motive. A qualified privilege protects statements made in good faith on a subject the speaker has a legitimate interest or duty to address.
The qualified privilege most relevant to business owners is the employment-reference privilege. When a former employer responds to a reference check and gives an honest, good-faith assessment of a former employee, that statement is qualifiedly privileged. The key word is qualified: the privilege is lost if the speaker acted with malice, meaning the statement was made from ill will or with knowledge of its falsity rather than in good faith. Minnesota also gives employers a statutory protection for job references: under Minn. Stat. § 181.967, a former employee cannot recover against an employer for disclosing job-performance information unless the employee proves by clear and convincing evidence that the information was false and defamatory and that the employer knew or should have known it was false and acted with malicious intent. That is a higher bar than an ordinary defamation claim carries. For a business deciding how to respond to a reference request, the privilege is protection only if the response is honest and made for a proper purpose. An exaggerated or retaliatory reference forfeits it. The recurring mistake I see is a former employer treating a qualified privilege as a license to say anything, when it protects only good-faith communication.
How does Minnesota’s anti-SLAPP statute affect a business defamation lawsuit?
Minnesota’s anti-SLAPP statute, the Uniform Public Expression Protection Act, was enacted in 2024 and changes how a defamation suit over public-facing speech proceeds. It lets a defamation defendant file a special motion asking the court to dismiss the case early. The statute “appl[ies] to a cause of action asserted in a civil action against a person based on the person’s . . . exercise of the right of freedom of speech . . . on a matter of public concern.” (Minn. Stat. § 554.08.) The same section states that the act applies to “a legal action against a person related to the communication . . . of consumer opinions or commentary, evaluations of consumer complaints, or reviews or ratings of businesses.” That language brings business-review suits within the statute’s reach, but coverage is not automatic. The Minnesota Court of Appeals held in Paragon Restorations, LLC v. Robinet Productions, LLC, No. A25-0826 (Minn. Ct. App. Dec. 29, 2025) that UPEPA does not automatically protect an online business review: the defendant must still show the review was speech on a matter of public concern, and a single review arising from a private payment dispute may not clear that threshold.
For a business considering suit over a review, this matters before you file. The defendant can bring a special motion for expedited relief, and Minnesota law gives the defendant a window to do so after being served. (Minn. Stat. § 554.09.) Filing that motion freezes the case, including discovery, so you cannot immediately use the lawsuit to compel the reviewer to identify themselves or produce documents. Once the motion is filed, the court “shall dismiss with prejudice” the claim unless your business “establish[es] a prima facie case as to each essential element of the cause of action.” (Minn. Stat. § 554.13.) And if the defendant prevails on the motion, the court “shall award court costs, reasonable attorney fees, and reasonable litigation expenses” to that defendant. (Minn. Stat. § 554.16.) The statute replaced Minnesota’s earlier anti-SLAPP law, so guidance written before 2024 describes a regime no longer in effect. The practical takeaway is that a business defamation suit over a public review is not a routine filing; it invites an early, structured challenge, and losing it means paying the other side. The same exposure runs the other direction before suit: a poorly aimed pre-suit demand can also create problems, as our article on how a cease-and-desist letter can backfire describes.
What can a Minnesota business recover in a defamation or disparagement claim?
A Minnesota business can pursue money damages for reputational and economic harm and, under the deceptive-trade-practices statute, an injunction ordering the false statement to stop. The injunction route is often the more practical remedy. The statute provides that “a person likely to be damaged by a deceptive trade practice of another may be granted an injunction against it,” and, importantly, that “proof of monetary damage, loss of profits, or intent to deceive is not required.” (Minn. Stat. § 325D.45, subd. 1.) For a business whose main goal is to get a false claim taken down rather than to collect a judgment, that lighter showing is significant.
Money damages are harder. As the public-concern section explained, presumed damages may be unavailable, leaving the business to prove actual reputational and economic loss. Attorney fees are limited: under the deceptive-trade-practices statute, a court “may award attorneys’ fees to the prevailing party” only if a complaining party “brought an action knowing it to be groundless” or the other party “willfully engaged in the trade practice knowing it to be deceptive.” (Minn. Stat. § 325D.45, subd. 2.) That is a narrow, fault-based fee provision, not a routine fee-shift. Realistically, the strongest business outcomes I see are an injunction and a correction or removal of the statement, not a large damages award. For how reputational damage is valued when damages are sought, see our discussion of how reputational harm is valued as damages in a business tort case.
Can I sue over a fake one-star online review?
Yes, if the review states a false fact about your business rather than a negative opinion, was seen by someone other than you, and harmed your reputation. A fabricated review posted by someone who was never your customer is the strongest version of this claim, because the false-fact element is clear.
Will my defamation case survive an anti-SLAPP motion?
Your case survives only if you can establish a prima facie case on every element of defamation. If you cannot, the court dismisses the claim with prejudice under Minnesota’s Uniform Public Expression Protection Act, and you may be ordered to pay the other side’s attorney fees.
Is a competitor's misleading comparison ad defamation or something else?
A competitor’s false factual claims in an advertisement are usually handled as trade libel or as a deceptive trade practice under Minnesota law. Because those claims appear in commercial advertising, they can also support a federal Lanham Act claim, which often runs alongside the state claim.
Can I sue Google or Yelp for a defamatory review on their platform?
Generally no. Under Section 230 of the federal Communications Decency Act, the platform is not treated as the publisher of a review written by a user. The proper defendant is the person who wrote the review, not the website that hosted it. That is why identifying an anonymous reviewer often becomes the first practical hurdle in these cases.
Do I have to demand a retraction before I sue?
Only for libel published in a newspaper. Minnesota law limits a newspaper-libel plaintiff to special damages unless a retraction was first demanded and refused. For an online review or a competitor’s statement, no retraction demand is required before you sue, although a written demand for correction is often a sensible first step regardless.
What if the statement is technically inaccurate but basically true?
A statement that is true in substance is not defamatory in Minnesota even if a minor detail is wrong. Courts look at the overall gist of the statement, so a small inaccuracy of expression will not turn an otherwise true statement into a defamation claim. The question is whether the gist of the statement is false, not whether every detail is exact.
A false statement that hurts your business is frustrating, but the legal question is narrower than the harm: whether the statement is a false statement of fact, whether you can prove the four elements, and whether a public-concern limit or an anti-SLAPP motion will reshape the case. In many situations the most practical result is an injunction or a correction, not a damages award, and a careful read of each statement, sentence by sentence, often shows which parts are actionable and which are protected opinion.
