The Racketeer Influenced and Corrupt Organizations (RICO) Act is a United States federal law that provides for extended criminal penalties and a civil cause of action for acts performed as part of an ongoing criminal organization.

RICO was enacted by section 901(a) of the Organized Crime Control Act of 1970 (enacted October 15, 1970) and is codified at 18 U.S.C. chapter 96 as 18 U.S.C. §§ 1961–1968. G Robert Blakey, an adviser to the United States Senate Government Operations Committee, drafted the law under the close supervision of the committee's chairman, Senator John Little McClellan. It was enacted as Title 9 of the Organized Crime Control Act of 1970, and signed into law by US President Richard M Nixon. While its original use in the 1970s was to prosecute the Mafia as well as others who were actively engaged in organized crime, its later application has been more widespread.

Beginning in 1972, thirty-three states adopted state RICO laws to be able to prosecute similar conduct.

Summary.

Under RICO, a person who has committed "at least two acts of racketeering activity" drawn from a list of 35 crimes (27 federal crimes and eight state crimes) within a 10-year period can be charged with racketeering if such acts are related in one of four specific ways to an "enterprise." Those found guilty of racketeering can be fined up to $25,000 and sentenced to 20 years in prison per racketeering count. In addition, the racketeer must forfeit all ill-gotten gains and interest in any business gained through a pattern of "racketeering activity."

A US Attorney who decides to indict someone under RICO has the option of seeking a pre-trial restraining order or injunction to temporarily seize a defendant's assets and prevent the transfer of potentially forfeitable property and to require the defendant to put up a performance bond. That provision was placed in the law because the owners of Mafia-related shell corporations often absconded with the assets. An injunction or performance bond ensures that there is something to seize in the event of a guilty verdict.

In many cases, the threat of a RICO indictment can force defendants to plead guilty to lesser charges, in part because the seizure of assets would make it difficult to pay a defense attorney. Despite its harsh provisions, a RICO-related charge is considered easy to prove in court since it focuses on patterns of behavior, as opposed to criminal acts.

RICO also permits a private individual "damaged in his business or property" by a "racketeer" to file a civil suit. The plaintiff must prove the existence of an "enterprise." The defendants are not the enterprise; in other words, the defendants and the enterprise are not one and the same. There must be one of four specified relationships between the defendants and the enterprise: either the defendants invested the proceeds of the pattern of racketeering activity into the enterprise (18 U.S.C. § 1962(a)); or the defendants acquired or maintained an interest in, or control of, the enterprise through the pattern of racketeering activity (subsection (b)); or the defendants conducted or participated in the affairs of the enterprise "through" the pattern of racketeering activity (subsection (c)); or the defendants conspired to do one of the above (subsection (d)). In essence, the enterprise is either the 'prize', 'instrument', 'victim', or 'perpetrator' of the racketeers. A civil RICO action can be filed in state or federal court.
