A one-time general counsel who was part of a team of whistleblowers who sued his former company for violating the False Claims Act in billing Medicaid and Medicare violated New York Rules of Professional Conduct on the confidentiality of client information, a federal appeals court held Friday.

The U.S. Court of Appeals for the Second Circuit upheld the dismissal of a qui tam action brought by attorney and one-time Unilab general counsel Mark Bibi and two other former executives, holding that the “False Claims Act does not preempt state ethical rules governing the disclosure of client confidences.”
