18 U.S.C. Sec. 1951 is a federal law on extortion that applies to non-robbery cases. Extortion is defined as the obtaining of property from another through the use of force, fear, or threats. Under 18 U.S.C. Sec. 1951, there are two types of non-robbery extortion: 1) Obtaining of property by wrongful use of actual or threatened force, violence, or fear; and 2) Obtaining of property by wrongful use of actual or threatened economic harm or threat of economic harm. In either case, the perpetrator must use wrongful means to obtain the property and the property must be obtained from another person. The person from whom the property is obtained must reasonably believe that the property will be obtained by the wrongful use of force, fear, violence, economic harm, or threats of economic harm. The penalty for non-robbery extortion is a fine and/or imprisonment of up to two years.
