Background
Bernard Shelton, a Michigan physician, was convicted on twenty-one counts of unlawfully distributing controlled substances to patients. The evidence showed he prescribed medications to patients with signs of drug-seeking behavior, failed to conduct physical examinations, and falsified medical records. One patient died from an overdose of oxycodone prescribed by Shelton. Shelton appealed, challenging the sufficiency of the evidence, the regulatory framework for prescribing, jury instructions, and a district court order requiring witnesses to wear masks during testimony.
The court’s reasoning
The court affirmed the conviction, finding that the government presented ample evidence that Shelton knowingly distributed controlled substances without a legitimate medical purpose. The jury could infer Shelton’s knowledge from his failure to examine patients, ignoring red flags like doctor shopping and failed drug screens, and his own statements acknowledging the risk of investigation. The court rejected arguments that the Attorney General lacked authority to define authorized prescribing, noting that the regulation aligns with the Controlled Substances Act and Supreme Court precedent. Regarding the mask mandate, the court held that while the Confrontation Clause generally requires face-to-face confrontation, the defendant failed to demonstrate that the mandate affected the outcome of the trial or undermined the fairness of the proceedings.
We conclude that ample evidence supports his conviction; the jury instructions were not confusing, misleading, or otherwise infirm; and the mask mandate was not reversible error.
United States v. Shelton, 24-1846 (6th Cir. July 1, 2026)
What it means going forward
The decision reinforces the ability of prosecutors to use objective criteria and circumstantial evidence to prove that a physician knowingly issued unauthorized prescriptions under the Controlled Substances Act. It also clarifies that mask mandates in federal courtrooms during trials do not automatically constitute reversible Confrontation Clause errors absent a showing of specific prejudice.
