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. He was sentenced to a mandatory minimum of twenty years on one count and concurrent sentences on others. Shelton appealed, challenging the sufficiency of the evidence, the regulatory framework, jury instructions, and a mask mandate for witnesses.
The court’s reasoning
The court affirmed the conviction, finding that the government presented ample circumstantial evidence that Shelton knew his prescriptions were unauthorized. The evidence included his failure to examine patients, ignoring red flags like doctor shopping and failed drug screens, and prescribing lethal drug combinations. The court rejected Shelton’s arguments that the Attorney General lacked authority to define authorization under the Controlled Substances Act, noting that the regulation aligns with statutory language and Supreme Court precedent. The court also found the jury instructions compliant with the Supreme Court’s decision in Ruan. Finally, the court held that the mask mandate did not violate the Confrontation Clause because Shelton failed to show prejudice or that the error affected the trial’s outcome.
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, No. 24-1971 (6th Cir. July 1, 2026)
What it means going forward
The decision reinforces the ability of federal prosecutors to convict physicians who prescribe controlled substances in violation of medical standards, provided the government proves the doctor knew the prescriptions were unauthorized. It also clarifies that mask mandates for witnesses during trials do not automatically violate the Confrontation Clause absent a showing of prejudice.
