Whistleblower cases brought under Federal and State False Claims Acts have been particularly effective in combating false and fraudulent claims by pharmaceutical manufacturers. According to publicly available data, well over $19 billion has been collected from pharmaceutical companies for various pricing, billing and marketing schemes that violate the Federal and State False Claims Acts, the Federal Ant-Kickback Statute, as well as other federal and states laws. These extraordinary recoveries are just the tip of the iceberg, and it is widely believed that billions of dollars in false and fraudulent claims and practices by pharmaceutical companies remain undetected. Whistleblowers acting under Federal and State False Claims Acts are critical to exposing such fraud, bringing pharmaceutical companies to justice, and recovering substantial funds owed by pharmaceutical companies to federal and state taxpayers.
