Medical Marijuana v. Horn

Updated Sep 5, 2026

In brief

A personal injury does not bar a civil RICO plaintiff from seeking triple damages for related economic losses to business or property.

Where it stands
Decided

Decided 5-4 · April 2, 2025 · Opinion by Justice Barrett

What it’s about
The Supreme Court held that a plaintiff can sue for triple damages under the civil Racketeer Influenced and Corrupt Organizations Act (RICO) for economic losses to their business or property, even if those financial losses were caused by a personal injury.
Who it affects
People who lose income or business-related property because of racketeering may seek triple damages, even if the financial loss followed a personal injury. That includes a worker who loses a job after using a falsely labeled product.

What it's about

The decision arose from a case where a truck driver lost his job after failing a drug test due to a CBD product that falsely claimed to contain no THC.

The decision interprets RICO's private lawsuit provision broadly for economic losses connected to racketeering.

Question presented

Are economic harms resulting from personal injuries properly considered injuries to “business or property by reason of” the defendant’s acts for purposes of a civil treble-damages action under the Racketeer Influenced and Corrupt Organizations Act?

What the Court decided

Holding

Under civil RICO, §1964(c), a plaintiff may seek treble damages for business or property loss even if the loss resulted from a personal injury. 80 F. 4th 130, affirmed and remanded.

From the opinions

“a plaintiff may seek treble damages for business or property loss even if the loss resulted from a personal injury.”

— Justice Amy Coney Barrett(majority)

“I would dismiss the writ of certiorari as improvidently granted.”

— Justice Clarence Thomas(dissent)

What's next

The case returns to the lower courts for further proceedings under the Supreme Court's rule. Lower courts must allow civil RICO claims for qualifying business or property losses even when those losses stem from a personal injury.
