What does a public figure have to prove to win a defamation suit?

Defamation is a statement that harms another person's reputation. Libel generally covers written or recorded statements and slander spoken ones. It is governed mainly by state common law and statutes, so the elements, defenses and damages vary from state to state. A claim generally requires a false statement presented as fact, its publication to a third party, the level of fault the law requires, and reputational or other legally recognized harm. Truth is generally a complete defense.¹

Calling a statement opinion does not automatically protect it. In 1990 the Supreme Court rejected a blanket exemption for opinion, but held that a statement on a matter of public concern must be provable as false before there can be liability, at least when the defendant is a media outlet. The Court also reaffirmed that statements that cannot reasonably be interpreted as stating actual facts are protected.²

The modern rule began with a newspaper advertisement. On March 29, 1960, The New York Times ran a full-page ad, "Heed Their Rising Voices," that appealed for money to support civil rights protesters and the legal defense of Martin Luther King Jr. L. B. Sullivan, a Montgomery, Alabama, city commissioner who supervised the police department, sued over statements in it, and an Alabama jury awarded him $500,000.³

The Supreme Court reversed in 1964. Writing for the Court, Justice William Brennan described "a profound national commitment to the principle that debate on public issues should be uninhibited, robust, and wide-open." The Court held that a public official cannot recover damages for a defamatory falsehood about his official conduct unless he proves actual malice: that the statement was made "with knowledge that it was false or with reckless disregard of whether it was false or not."³

Actual malice is not the same as spite or ill will, which is what "malice" can mean elsewhere in defamation law, and it must be proved by clear and convincing evidence.¹ Reckless disregard is not measured by whether a reasonably careful publisher would have checked further; there must be evidence that the defendant "in fact entertained serious doubts as to the truth of his publication."⁴ A failure to investigate does not by itself show actual malice, but "the purposeful avoidance of the truth is in a different category."⁵

Three years after Sullivan, a majority of the Court extended the rule to public figures in Curtis Publishing Co. v. Butts. In Gertz v. Robert Welch in 1974, the Court described two kinds of public figure: a person with "such pervasive fame or notoriety that he becomes a public figure for all purposes and in all contexts," and, more commonly, a person who "voluntarily injects himself or is drawn into a particular public controversy" and becomes a public figure for a limited range of issues.⁶

Private individuals face a lower bar. For their suits against publishers and broadcasters, Gertz lets each state set its own standard as long as it does not impose liability without fault. When the speech involves a matter of public concern, they cannot recover presumed or punitive damages without proving actual malice.⁶¹ When a media defendant's speech concerns a matter of public concern, the plaintiff must also prove that the statement was false, rather than the defendant having to prove it true.⁷

Justice Clarence Thomas has called for reconsidering the actual-malice standard for public figures since 2019.⁸ Dissenting when the Court declined on June 29, 2026 to hear Alan Dershowitz's appeal in his defamation suit against CNN, he wrote, quoting his own 2021 dissent, which quoted Judge Silberman of the D.C. Circuit, that the actual-malice standard for public figures bears "no relation to the text, history, or structure of the Constitution," and that the founding generation believed public figures, if anything, had stronger claims for damages when they were defamed. Justice Neil Gorsuch joined that dissent.⁹

Gorsuch set out his own case in 2021. Dissenting in Berisha v. Lawson, he wrote that since 1964 the media had "shifted in ways few could have foreseen" and that actual malice had "evolved from a high bar to recovery into an effective immunity from liability." He cited data showing that defamation trials involving publications fell from an average of 27 a year in the 1980s to 3 in 2018.⁸

Some defenders of the rule answer that the problem lies elsewhere. Nabiha Syed, writing for the Knight First Amendment Institute in 2021, argued that most of the falsehoods the two justices worry about are not governed by defamation law, and that Gorsuch's proposal would further imperil journalists amid "meritless litigation over unpleasant truths about the powerful."¹⁰ The Court has not agreed to reconsider Sullivan, which remains the governing rule.⁹
