Fraud
A knowing misrepresentation or concealment of a material fact, made to induce another person to act, on which the person justifiably relies to his or her harm. The elements vary by state. In federal court, a party alleging fraud must state with particularity the circumstances constituting fraud (Fed. R. Civ. P. 9(b)). Fraud can also be a crime, for example mail fraud and wire fraud (18 U.S.C. §§ 1341, 1343).
