The U.S. Supreme Court has rejected a $1.2 million defamation judgment an airline pilot received after the airline reported that he could pose a security risk, Forbes reports. Justice Sonia Sotomayor cited the New York Times v. Sullivan in ruling that Air Wisconsin was entitled to immunity for statements its employees made to the Transportation Safety Administration as long they weren't materially false, Forbes further reports. The employees reported that the pilot, who failed multiple tests, was "mentally unstable." Forbes also reports "the decision reiterates the key test for whether a statement is defamatory. For a statement to be materially false, the court said, it must produce a different effect on the mind of the person who receives it than would the truth."
