Boyle v. United States

Background

Edmund Boyle and others were tried for a series of bank thefts across several States, and the Government charged them under the federal racketeering law (RICO). At trial the judge told the jury they could find an "association-in-fact" enterprise from an ongoing, informal organization that functioned as a continuing unit; Boyle asked for a special instruction requiring a separate, ascertainable formal structure, which the judge refused. Boyle was convicted and the conviction was affirmed by the lower court.

Reasoning

The Court addressed whether an association-in-fact enterprise must have "an ascertainable structure beyond that inherent in the pattern of racketeering activity." The justices held that an enterprise must have a structure with three basic features: a purpose, relationships among members, and enough longevity to pursue that purpose. But the Court said judges need not use the exact phrase Boyle proposed and that juries may infer the enterprise’s existence from how the group behaved. The Court rejected the idea that RICO requires formal trappings like hierarchy, dues, or initiation rituals.

Real world impact

The decision upholds the trial instructions and affirms Boyle’s conviction, making it clear prosecutors can prove an enterprise by showing a continuing group with purpose and relationships, even if informal. That will affect how prosecutors and defense lawyers frame evidence in RICO cases: juries may infer an enterprise from coordinated criminal behavior rather than formal organizational documents. The ruling resolves conflicting appellate views and guides future prosecutions.

Dissents or concurrances

Justice Stevens dissented, arguing Congress intended "enterprise" to mean business-like organizations with an existence separate from the crimes; he would have required clearer proof of organizational structure apart from the predicate crimes.
