What qualifies as a pattern of racketeering activity under RICO?
Executive summary
A “pattern of racketeering activity” under federal RICO requires at least two predicate acts drawn from the statute’s list, committed within a statutory time window and shown to be related and continuous or threatening continuity (two-or-more predicates within ten years is the commonly cited baseline) [1] [2] [3]. Courts and prosecutors impose two core tests: relatedness (shared purpose, participants, methods, victims, or nexus to the same enterprise) and continuity (closed‑ or open‑ended showing of ongoing or threatened future criminality) [4] [5] [6].
1. Minimum numeric rule: “Two or more” predicate acts — but that’s not the whole story
Statute and practice require at least two predicate offenses to establish a pattern, and many summaries state those predicates must occur within a ten‑year period [1] [3] [6]. However, commentators and practitioners stress that simply showing two crimes without more usually fails — the acts must be tied together conceptually and temporally [7] [4].
2. Relatedness: what connects the acts to one another and to an enterprise
Courts look for a relationship among predicates — for example same victims, same methods, same participants, or that the acts further the goals of the same enterprise. The government can show relatedness by proving the racketeering acts benefitted the enterprise, were enabled by the enterprise, were committed at the enterprise’s behest, or shared distinguishing characteristics [5] [6] [4].
3. Continuity: real or threatened continuity of criminal conduct
H.J. Inc. v. Northwestern Bell and DOJ guidance frame “continuity” as either closed‑ended (a series of related predicates over a substantial period) or open‑ended (acts that pose a threat of continuing racketeering into the future). The Supreme Court and DOJ materials emphasize that predicates must amount to or pose a threat of continued criminal activity — not merely two isolated incidents [2] [5] [6].
4. Timing windows and practical limits prosecutors use
Authoritative sources repeatedly state the typical statutory framework limit is two predicates within ten years; some practice guides and state law summaries add nuance (e.g., other materials cite a five‑year window for certain formulations, or note timing of last predicate relative to prior ones) [1] [3] [8]. The DOJ manual and court decisions temper the literal numeric rule by requiring continuity and relatedness as substantive barriers [2] [6].
5. Predicate acts: a long, varied list that matters to pattern analysis
“Racketeering activity” is defined by statute and encompasses many federal and state offenses — fraud, bribery, extortion, money laundering, trafficking, violent crimes, and more — and the particular mix of predicates affects both relatedness and continuity analyses because disparate crimes may be harder to tie into a single pattern [3] [9] [10].
6. How prosecutors and defense see the element differently
Prosecutors treat the pattern element as flexible and capable of capturing diverse organized‑crime behavior; DOJ guidance stresses a “liberal construction” to effectuate RICO’s remedial purpose [2] [11]. Defense practitioners and some commentators stress this is the government’s weakest link — courts require specific proof that predicates are related and continuous, so a defense attack often focuses on breaking the chain of relatedness or arguing lack of continuity [7] [12].
7. Civil RICO vs. criminal RICO: the pattern question carries into both arenas
Civil RICO plaintiffs must meet the same pattern element, and courts have imposed additional hurdles (e.g., pleading specificity for fraud predicates). Practical consequences differ: civil plaintiffs may seek treble damages and injunctive relief while criminal defendants face imprisonment and forfeiture [4] [13].
8. Key case law and guidance to consult — and limits of available reporting
H.J. Inc. v. Northwestern Bell (continuity and relatedness framework) and subsequent DOJ manuals and Sentencing Commission primers are central to understanding pattern doctrine; the Justice Manual and Sentencing Commission materials explicitly discuss the continuity and relatedness tests [2] [14] [6]. Available sources do not mention newer post‑2025 case law beyond the cited DOJ and primer materials — consult current case law if a recent decision might change these standards [2] [14].
9. Practical takeaway for non‑lawyers and litigants
Meeting the numeric minimum of two predicates is necessary but not sufficient: prosecutors must also prove the predicates are related and demonstrate continuity or a real threat of ongoing crime tied to an enterprise. Defendants and civil targets can and often do challenge pattern allegations by attacking relatedness, timing, and continuity [7] [5] [12].
Limitations: This analysis relies on statute summaries, DOJ guidance, legal primers and practice commentary in the provided sources; it does not attempt to summarize every circuit split or post‑2025 rulings because those are not in the available reporting [2] [14].
