Illinois Court: Jury Must Decide Actual Malice in Campaign Mailer Defamation Case

Illinois Court: Jury, Not Judge, Must Decide Actual Malice in Campaign Mailer Defamation Case

The Illinois Appellate Court, Third District, ruled on July 13, 2026 that a jury, not a judge, must decide whether a political campaign acted with actual malice in mailers accusing Burr Ridge Mayor Gary Grasso of $36,000 in tax fraud, reversing summary judgment in Grasso v. Mottl, 2026 IL App (3d) 240717.

Jurisdiction scope: This ruling comes from the Illinois Appellate Court, Third District, and directly governs the circuits within that district. The underlying actual malice standard derives from the U.S. Supreme Court's decision in New York Times Co. v. Sullivan and applies to public officials nationwide, not only in Illinois. This article is general legal information, not legal advice for any specific case.

What Happened

On July 13, 2026, the Illinois Appellate Court, Third District, issued its opinion in Grasso v. Mottl, 2026 IL App (3d) 240717. The dispute arose from a local campaign in Burr Ridge, Illinois, during which Gary Grasso, the sitting mayor, was the subject of political mailers distributed by an opposing campaign. The mailers alleged that Grasso had committed tax fraud and defrauded the government of more than $36,000 through improper property tax exemptions.

Grasso sued the campaign and its political consultant, Collin Corbett, for defamation. In July 2024, a DuPage County circuit judge granted summary judgment for the remaining defendants, ruling that Grasso had not produced enough evidence of the actual malice required for a public official's defamation case to proceed.

The appellate panel reversed that ruling. The court reviewed the opposition research report the campaign relied on, prepared by a third party political research firm, which indicated Grasso may have improperly received a homestead exemption tied to a DuPage County residence while also receiving one tied to a property in Cook County. That report supported at most an estimated $12,000 in improper exemptions over a two year overlap. The mailers, however, asserted more than $36,000 in fraud, a figure the defendants could not explain when questioned during discovery.

Because Corbett could not account for how the campaign arrived at the higher number, the appellate court held that a reasonable jury could find the mailers were published with reckless disregard for the truth, satisfying the actual malice standard. The case now returns to the circuit court, where the actual malice question will proceed toward a jury rather than being resolved as a matter of law. The appellate court did not decide whether the mailers' underlying fraud accusations were true or false; that question, along with the ultimate actual malice determination, remains open and contested.

What the Law Actually Says

Under the First Amendment, a public official who sues for defamation must prove the defendant acted with actual malice, meaning the statement was published with knowledge it was false or with reckless disregard for whether it was false. This standard comes from New York Times Co. v. Sullivan, 376 U.S. 254 (1964). For background on defamation claims generally, see our defamation law hub; the actual malice standard specifically is covered in more depth on our public figure defamation page.

Actual malice is a much higher bar than the ordinary negligence standard that applies when a private individual sues for defamation. A private figure typically only needs to show the defendant was careless in checking the facts before publishing. A public official, by contrast, must show the defendant either knew the statement was false or seriously doubted its truth and published it anyway, a subjective standard that often turns on evidence like internal communications, research files, and testimony about what the speaker knew. Our overview of the elements of a defamation claim walks through everything a plaintiff generally must prove.

A false accusation that someone committed a crime, such as tax fraud, is generally treated as defamation per se in Illinois, meaning damages can be presumed without separate proof of specific financial harm because the accusation is inherently damaging to reputation. That doctrine does not remove the actual malice requirement for a public official plaintiff; it only affects how damages are proved once liability is established.

Analysis: Why This Matters

The following is analysis from the Recording Law Editorial Team.

This ruling is a reminder that actual malice is often a factual question for a jury, not something a defendant can foreclose merely by denying knowledge of falsity. The appellate court's reasoning turned on a gap between what the campaign's own research showed and what the mailers claimed, combined with the defendants' inability to explain that gap under oath. A documented internal source paired with an unexplained departure from it in public messaging is the kind of circumstantial evidence courts have long treated as probative of reckless disregard, even though actual malice ultimately requires proof of the defendant's subjective state of mind at the time of publication.

The decision does not resolve whether the mailers' underlying accusations of tax fraud were true or false, and it does not predict how a jury will ultimately rule on actual malice. It holds only that the question was not appropriate for resolution on summary judgment given this record. For campaigns and consultants, the case signals that opposition research can become a liability if public-facing messaging outruns what the underlying research supports, particularly where a defendant cannot later explain the basis for a higher figure used in an attack. For public officials weighing defamation claims over campaign material, it illustrates that surviving summary judgment on actual malice is possible where there is a documented, unexplained discrepancy between internal research and public claims, though the constitutional bar to winning at trial remains high either way.

How This Affects You

Public officials who believe a campaign mailer, advertisement, or public statement defamed them must clear the actual malice bar before they can recover damages under the framework established in New York Times Co. v. Sullivan. That generally means gathering evidence, often through discovery, about what the speaker knew or believed at the time of publication, not merely whether the statement turned out to be false. Political campaigns and consultants who rely on opposition research should be aware that courts may scrutinize any gap between what a report actually supports and what ends up in public-facing material. Anyone evaluating a potential defamation claim or defense arising from campaign communications should consult a licensed attorney in their jurisdiction, since outcomes depend heavily on the specific facts and applicable state law.

Frequently Asked Questions

Can you sue over a campaign mailer?

Yes. Political mailers are subject to the same defamation laws as other publications. A public official plaintiff must additionally prove actual malice, meaning the speaker knew the statement was false or acted with reckless disregard for the truth, under the standard set in New York Times Co. v. Sullivan, 376 U.S. 254 (1964).

What is actual malice in defamation law?

Actual malice is a legal standard requiring a defamation plaintiff who is a public official or public figure to prove the defendant published a false statement either knowing it was false or with reckless disregard for whether it was true. It focuses on the defendant's knowledge or doubts about the statement's accuracy at the time of publication, not on ill will.

Can a mayor sue for defamation?

Yes, a mayor can sue for defamation, but because a mayor is generally considered a public official, the mayor must prove actual malice rather than the lower negligence standard that applies to private individuals in most states.

Is calling someone a fraud defamation?

Falsely accusing someone of fraud, which is a crime in most states, can constitute defamation per se, meaning harm can be presumed without separate proof. Whether a specific accusation is actionable depends on whether it is false, whether it is presented as fact rather than opinion, and, for a public official, whether the plaintiff can prove actual malice.

What happens when an appellate court reverses summary judgment?

Reversing summary judgment means the appellate court found a genuine factual dispute that a jury, not a judge, should resolve. It does not mean either side has won the underlying claim; it sends the case back to the trial court for further proceedings, which can include a trial.

Who has to prove actual malice, the plaintiff or the defendant?

The plaintiff, a public official or public figure suing for defamation, bears the burden of proving the defendant acted with actual malice by clear and convincing evidence, a higher standard than the preponderance of the evidence used in most civil cases.

Is the Grasso v. Mottl case over?

No. As of July 19, 2026, Grasso v. Mottl is an ongoing case. The appellate court's ruling sends the actual malice question back to the circuit court, where it can proceed toward a jury trial. This article will be updated as the case develops.
