Public Figures
Under the First Amendment of the United States Constitution, as set forth by the U.S. Supreme Court in the 1964 Case, New York Times v Sullivan, where a public figure attempts to bring an action for defamation, the public figure must prove an additional element: That the statement was made with "actual malice". In translation, that means that the person making the statement knew the statement to be false, or issued the statement with reckless disregard as to its truth. For example, Ariel Sharon sued Time Magazine over allegations of his conduct relating to the massacres at the Sabra and Shatila refugee camps. Although the jury concluded that the Time story included false allegations, they found that Time had not acted with "actual malice" and did not award any damages.
The concept of the "public figure" is broader than celebrities and politicians. A person can become an "involuntary public figure" as the result of publicity, even though that person did not want or invite the public attention. For example, people accused of high profile crimes may be unable to pursue actions for defamation even after their innocence is established, on the basis that the notoriety associated with the case and the accusations against them turned them into involuntary public figures.
