a landmark Supreme Court decision in 1964 that established the principle of "actual malice" for public figures in libel cases. The case was brought by L.B. Sullivan, a city commissioner in Alabama, over a Times article that contained minor factual errors. The Court ruled that for a public figure to win a libel suit, they must prove that the defendant acted with "actual malice," meaning they knew the information was false or acted with reckless disregard for the truth.
