Boyle v. United States
The Supreme Court ruled that an informal group of people who band together for a common purpose can count as an 'enterprise' under the federal racketeering law, even without a name, hierarchy, leader, or any business-like structure beyond what the crimes themselves require.
The decision upheld the conviction of a man involved in a loosely organized ring of bank thieves, confirming that prosecutors do not need to prove elaborate organizational features to win a racketeering case against informal criminal groups.
“As we said in Turkette, an association-in-fact enterprise is simply a continuing unit that functions with a common purpose.”
The Court's core explanation of what a loosely organized criminal group needs to count as an 'enterprise.'
How it got here: A jury convicted Boyle after the trial court's jury instructions on 'enterprise'; the Second Circuit affirmed, and the Supreme Court agreed to resolve a circuit split.
The Case in Depth
What happened
Edmund Boyle took part in a loosely organized group that committed dozens of bank thefts across several states during the 1990s, mainly stealing from night-deposit boxes. The group had no leader, hierarchy, or long-term plan — members were recruited as needed and split the proceeds after each job. Boyle was charged with violating the federal racketeering law for participating in this group's affairs.
The question before the Court
Does a loose, informal group of criminals with no name, leader, or hierarchy still count as an 'enterprise' under the federal racketeering law?
The Court's answer
Yes — the Court ruled that an informal, loosely organized group can qualify as a RICO 'enterprise' without any business-like features such as a hierarchy, fixed roles, name, meetings, or dues. All that's required is a shared purpose among the members, ongoing relationships between them, and enough duration for them to actually pursue that purpose together.
The Court also clarified that juries don't need to be told the enterprise's structure must be 'ascertainable' — that's redundant, since any element a jury must find beyond a reasonable doubt is inherently ascertainable. And while the existence of the enterprise is a separate legal element from the pattern of crimes committed, a jury may still infer the enterprise's existence from the same evidence that proves the crimes, when the facts allow it.

Why it matters
Federal prosecutors can continue using the racketeering law against loosely organized crews of criminals — not just mob-style organizations with clear hierarchies. This makes it easier to charge informal groups, like ad hoc theft rings, under a law that carries much harsher penalties than ordinary conspiracy charges.
What changes now
This is a final merits decision resolving a circuit split over what jury instructions are required to define a racketeering 'enterprise.' Boyle's conviction and 151-month sentence stand. Lower courts nationwide now have a single standard: association-in-fact enterprises need only a purpose, relationships, and sufficient longevity — no additional business-like or hierarchical features — when instructing juries in racketeering prosecutions.
What this does not decide
The Court did not decide that any group of people who commit crimes together automatically forms an enterprise — it still requires proof of an ongoing organization with a shared purpose and continuity. The ruling also does not eliminate the enterprise element as separate from the pattern of crimes, even though the same evidence may sometimes prove both.
Concurrences and dissents
Dissent — Justice Stevens
Justice Stevens argued that Congress meant 'enterprise' to cover only business-like groups with an existence separate from the crimes their members commit, pointing to the statute's list of formal business entities and the Court's earlier Reves decision. He would have required jury instructions demanding proof of rules, routines, or processes showing the group's continuing operations beyond the predicate crimes themselves. He concluded the trial evidence here showed only sporadic, ad hoc theft with no such separate existence, so the conviction should not stand.
How the Court got there
The legal reasoning, step by step
- The Court read the racketeering law's broad definition of 'enterprise' — which includes 'any... group of individuals associated in fact although not a legal entity' — together with the instruction that the law be read broadly to serve its purposes.
- Drawing on its earlier decision in Turkette (a 1981 case defining what counts as a racketeering 'enterprise'), the Court held that an informal group enterprise must have three structural features: a shared purpose, relationships among its members, and enough staying power for members to pursue that purpose together.
- The Court rejected the argument that a jury must be told the structure has to be 'ascertainable,' reasoning that any element a jury must find beyond a reasonable doubt is, by definition, ascertainable — adding that word would just confuse jurors.
- The Court also held that while the existence of an enterprise must be proved as a separate element from the pattern of crimes committed, the same evidence can sometimes prove both — a jury may infer the enterprise's existence from evidence of the pattern of crimes itself.
- Applying this framework, the Court concluded that Congress did not require additional features like a hierarchy, fixed roles, dues, meetings, or an enterprise name, since nothing in the statute's text demands business-like organization.
- Because the trial court's instructions already captured these requirements — telling jurors the enterprise needed an ongoing framework and a continuing common purpose, distinct from proving the crimes themselves — the Court found no error and let the conviction stand.
