Defamation Per Se

Defamation per se is a common-law doctrine, applied primarily in U.S. and other Anglo-American jurisdictions, under which certain false statements are considered so obviously damaging to a person's reputation that injury is presumed. A plaintiff suing on a per se theory does not have to plead or prove special damages (specific economic loss); general damages flow automatically from the nature of the statement itself.

Courts have traditionally recognized four categories of statements as defamatory per se:

• Allegations that the plaintiff committed a serious crime (typically one involving moral turpitude or carrying potential imprisonment).
• Allegations that the plaintiff has a "loathsome" or contagious disease (historically venereal disease or leprosy).
• Statements attacking the plaintiff's fitness, competence, or integrity in their trade, business, or profession.
• Allegations of serious sexual misconduct, including, at common law, imputations of unchastity to a woman.

This doctrine contrasts with defamation per quod, where the defamatory meaning is not apparent on the face of the statement and the plaintiff must plead extrinsic facts plus special damages.

The per se framework remains widely used at the state level in the United States, though it has been substantially reshaped by First Amendment doctrine. New York Times Co. v. Sullivan (1964) imposed an "actual malice" requirement on public-official plaintiffs, and Gertz v. Robert Welch, Inc. (1974) held that states may not allow presumed or punitive damages without a showing of actual malice when the speech concerns matters of public concern. As a result, the practical effect of per se categorization is now narrower, particularly in cases involving public figures or public-interest reporting.

Some jurisdictions have abolished or modified specific categories — notably the "unchastity" branch — as inconsistent with modern equality norms. Outside the U.S., comparable concepts exist in English law as "slander actionable per se," codified in part by the Defamation Act 2013.
