18 U.S.C. § 1962

Elements

1. Culpable person (§ 1961(3)) distinct from the enterprise under (c)

   It shall be unlawful for any person

   Under § 1962(c), a corporate defendant cannot be both the "person" and the "enterprise" (nor can it evade distinctness merely by defining the enterprise as the corporation plus its own employees/agents acting in the course of business).

2. Enterprise (§ 1961(4)): legal entity or association-in-fact

   any enterprise

   Turkette and Boyle govern association-in-fact enterprises: purpose + relationships among associates + longevity sufficient to pursue the purpose.

3. Interstate or foreign commerce nexus

   engaged in, or the activities of which affect, interstate or foreign commerce

   A de minimis effect on interstate commerce by the enterprise's activities (including detrimental effects on victims engaged in commerce) suffices.

4. Defendant employed by or associated with the enterprise (§ 1962(c))

   employed by or associated with

   Covers both insiders ("employed by") and outsiders ("associated with") who exert control or participate in directing enterprise affairs, but excludes the enterprise itself.

5. Conduct or participate in the conduct of enterprise affairs (§ 1962(c) operation or management test)

   to conduct or participate, directly or indirectly, in the conduct of such enterprise's affairs

   Reves v. Ernst & Young establishes the "operation or management" test: defendant must have some part in directing the enterprise's affairs (including lower-rung participants acting under upper management's direction, or outsiders exerting control via bribery). Merely furnishing professional services is insufficient.

6. Pattern of racketeering activity (§ 1961(5)): at least two predicate acts with relatedness and continuity

   a pattern of racketeering activity

   Alternative to `debt` ("or collection of unlawful debt"). Under H.J. Inc. v. Northwestern Bell, statutory minimum of two predicates within 10 years is necessary but not sufficient: requires relatedness + continuity (`pattern.relatedness` and `pattern.continuity`).

7. Racketeering activity (§ 1961(1) enumerated state and federal predicate offenses)

   racketeering activity

   (formerly `variant unmodeled/remaining-section-1961-1`) Explicit open catalogue: murder, kidnapping, gambling, arson, robbery, bribery, narcotics, immigration-document offenses, financial-institution fraud, false statements, money laundering, and additional obstruction, securities, bankruptcy, and state-law predicates remain to be decomposed. Predicate offenses must fall within the exhaustive list in 18 U.S.C. § 1961(1); the child entries below are a research subset, and the UNMODELED_PREDICATE_CATALOGUE is intentionally open rather than an implicit claim that the subset is complete. Fraud predicates must be pleaded with particularity under Fed. R. Civ. P. 9(b).

8. Collection of an unlawful debt (§ 1961(6)) — alternative to pattern of racketeering activity

   collection of unlawful debt

   Unlike `pattern`, collection of an unlawful debt requires only a single collection of a debt arising from illegal gambling or usurious lending at >= 2x the enforceable rate (e.g. tribal payday lending cases such as Gibbs v. Haynes Invs.).

9. Use or investment of racketeering income in an enterprise (§ 1962(a))

   to use or invest, directly or indirectly, any part of such income, or the proceeds of such income, in acquisition of any interest in, or the establishment or operation of,

   Under § 1962(a), the defendant must have received income from a pattern of racketeering (or unlawful debt collection in which the person participated as a principal under 18 U.S.C. § 2) and used or invested that income in an enterprise; civil § 1962(a) requires "investment injury" distinct from harm caused by the predicate acts themselves.

10. Acquire or maintain interest in or control of an enterprise (§ 1962(b))

    to acquire or maintain, directly or indirectly, any interest in or control of

    Under § 1962(b), the acquisition or maintenance of interest/control in the enterprise must occur *through* the pattern of racketeering activity or unlawful debt collection, and civil plaintiffs must show "acquisition injury" distinct from predicate-act injury.

11. Conspiracy to violate § 1962(a), (b), or (c) (§ 1962(d))

    to conspire to violate any of the provisions of subsection (a), (b), or (c) of this section

    Note tension in older or lower-court civil opinions (e.g. Goldfine) that sometimes recite a requirement that each defendant agreed to commit two predicates; Salinas controls in criminal and modern civil cases, though civil § 1962(d) still requires a viable underlying § 1962(a)-(c) violation and an overt act that is itself a RICO predicate under Beck v. Prupis (529 U.S. 494 (2000)).

12. Civil RICO injury to business or property (18 U.S.C. § 1964(c))

    It shall be unlawful for any person

    Damages must be concrete, clear, and definite (not speculative or unripe pending exhaustion of contractual/collateral remedies), and must be domestic under RJR Nabisco v. European Community (579 U.S. 325 (2016)).

13. But-for and proximate causation ("by reason of", 18 U.S.C. § 1964(c))

    It shall be unlawful for any person

    Under Holmes v. SIPC (503 U.S. 258 (1992)), Anza, and Hemi Group, proximate cause requires "some direct relation between the injury asserted and the injurious conduct alleged".

14. Civil aiding and abetting a RICO violation (rejected as a private cause of action)

    as a principal within the meaning of section 2, title 18, United States Code

    Following Central Bank of Denver (511 U.S. 164 (1994)), most courts hold that 18 U.S.C. § 1964(c) does not authorize private civil aiding-and-abetting liability under § 1962(c) (though criminal aiding and abetting under 18 U.S.C. § 2 applies, and § 1962(a) expressly cross-references 18 U.S.C. § 2).

15. De minimis open-market securities investment proviso (§ 1962(a))

    A purchase of securities on the open market for purposes of investment, and without the intention of controlling or participating in the control of the issuer, or of assisting another to do so, shall not be unlawful under this subsection if the securities of the issuer held by the purchaser, the members of his immediate family, and his or their accomplices in any pattern or racketeering activity or the collection of an unlawful debt after such purchase do not amount in the aggregate to one percent of the outstanding securities of any one class, and do not confer, either in law or in fact, the power to elect one or more directors of the issuer.

    Express statutory safe harbor in § 1962(a) for open-market passive investment purchases totaling <1% of any class of voting/non-voting securities without power to elect a director. Note verbatim typo in statute text ("any pattern or racketeering activity").

16. Statute of limitations (4-year civil under Agency Holding; 5-year criminal under 18 U.S.C. § 3282)

    It shall be unlawful for any person

    Civil RICO claims are governed by a 4-year statute of limitations borrowed from the Clayton Act (Agency Holding Corp. v. Malley-Duff, 483 U.S. 143 (1987)), accruing under the injury-discovery rule (Rotella v. Wood, 528 U.S. 549 (2000)).

17. Fifth Amendment Double Jeopardy bar against successive RICO conspiracy/substantive prosecutions

    to conspire to violate any of the provisions of subsection (a), (b), or (c) of this section

    Evaluated under a totality-of-the-circumstances five-factor test (time, persons, statutory offenses, overt acts/predicates, locus/enterprise) to determine whether two indictments charge the same enterprise/conspiracy.

18. Claim preclusion / release by prior class-action settlement

    It shall be unlawful for any person

    General affirmative defense litigated in civil RICO class actions.

19. Parol evidence rule raised to bar extrinsic evidence of fraudulent misrepresentations

    It shall be unlawful for any person

    Rejected as a bar to mail/wire fraud RICO predicates sounding in tort rather than contract enforcement.
