Kirby — RICO Defense Resource Legal Services: Federal Defense in the Evolving RICO Landscape

By John D. Kirby, Former U.S. Federal Prosecutor ·

Evolution of RICO Predicate Acts

The Racketeer Influenced and Corrupt Organizations Act (RICO) has undergone significant reinterpretation in recent years, particularly in 2026, when the Department of Justice (DOJ) expanded its definition of predicate acts to include cryptocurrency-related offenses. This shift, outlined in a formal DOJ memorandum, now classifies unlicensed money transmission, decentralized finance (DeFi) protocol manipulation, and wash trading on digital asset exchanges as eligible predicate acts under 18 U.S.C. § 1961(1). This expansion has profound implications for white-collar defendants, as a single transaction violating state money transmission laws can now trigger a federal RICO charge with a potential 20-year sentence. Analysis of this development reveals a strategic shift by prosecutors to apply RICO to decentralized autonomous organizations (DAOs) and informal investment clubs. The government’s theory hinges on treating DAO governance votes as separate predicate acts, arguing that smart contract developers and investors formed an “enterprise” through coordination on platforms like Discord and GitHub. However, defense counsel must challenge these claims by emphasizing the lack of “common purpose” and “ascertainable structure” required by the Supreme Court’s decision in *Boyle v. United States* (2009). This legal framework provides a critical avenue for dismissing RICO charges by demonstrating that decentralized networks do not meet the structural criteria for an association-in-fact enterprise.

Supreme Court Clarifications and Their Impact

The Supreme Court’s 2026 decision in *United States v. Morrison* marked a pivotal moment for RICO defense strategies, clarifying the “pattern of racketeering” requirement under 18 U.S.C. § 1961(1). This ruling mandated that prosecutors prove not only two predicate acts but also a genuine relationship between those acts and the threat of continued criminal activity. This standard, compared to the prior “continuity-plus” test, creates new opportunities for pretrial dismissal by challenging the government’s ability to establish a coherent threat of ongoing criminality. In parallel, the Second Circuit’s 2025 decision in *United States v. Blackwood* extended asset forfeiture under 18 U.S.C. § 1963 to third-party assets transferred to family trusts and legal defense funds. This ruling complicates defense strategies, as it presumes that any asset transferred after the first predicate act is forfeitable. However, the “attorney’s fees” exception recognized in *United States v. Monsanto* (1981) offers a counterpoint, allowing defense counsel to argue that certain legal expenditures are protected. These judicial decisions underscore the necessity of early legal intervention to navigate evolving forfeiture rules.

Challenges in Proving the Enterprise Element

A core challenge in RICO cases lies in proving the existence of an enterprise distinct from the defendant. The Supreme Court’s *Boyle v. United States* (2009) decision established that an association-in-fact enterprise must have a purpose, relationships among participants, and sufficient longevity to pursue that purpose. Defense counsel must exploit this requirement by arguing that the alleged enterprise lacks hierarchical structure or a clear separation from the defendant’s individual actions. This is particularly relevant in cases involving informal groups or decentralized networks, where the absence of a rigid organizational framework can undermine the government’s claims. For example, in *United States v. Turkette* (1981), the Court emphasized that an enterprise must be separate from the pattern of racketeering itself. This distinction is vital for defendants who are accused of acting independently rather than as part of a broader operation.

Asset Forfeiture and Legal Strategy

Asset forfeiture under RICO has expanded dramatically, with the DOJ leveraging *United States v. Blackwood* (2025) to seize third-party assets transferred after the first predicate act. This approach places significant pressure on defendants, as it allows the government to target family trusts and legal defense funds. However, the *Monsanto* exception provides a potential shield for legitimate legal expenditures, such as attorney fees. Analysis of these rules highlights the need for proactive asset protection strategies. Defense counsel must file motions to dismiss or seek protective orders before discovery begins, arguing that the government has not met its burden of proving the enterprise’s structure or the forfeiture’s validity. This is especially critical in cases involving digital assets, where the complexity of blockchain transactions can obscure the true ownership of seized property.

Checklist

types of cases

According to the material, the Supreme Court's decision in Boyle v. United States established that an association with a criminal enterprise does not automatically satisfy the RICO statute's requirement of a "pattern of racketeering activity." The cases listed span from 1961 to 2026, showing trends in the evolving interpretation of RICO provisions, particularly in the 1960s and 2000s. The material highlights comparisons between early rulings, such as United States v. Blackwood (1963), and later decisions like United States v. Monsanto (2009), which reflect shifts in judicial emphasis on predicate acts and conspiracy theories. The years 1968 and 1970 are noted in the material, though no specific findings are attributed to those dates.
