Case Overview

A horse trainer injected racehorses with performance-altering drugs, affecting parimutuel betting outcomes.

Legal Issue

Causation and risk of deprivation in fraud

Decision

Fraud is made out where dishonest conduct puts the victim's economic interests at risk, even if no individual victim relied on the deceit.

Why this Case Matters

Confirmed that fraud captures conduct that exposes victims to risk of loss, even without direct reliance on a misrepresentation.

What Changed Because of This Case

Tightened the link between dishonest conduct and risk of deprivation as a basis for liability.

Practical Implications for Investigators

Frame the theory of deprivation around the risk created by the dishonest scheme, not only realized losses.
