According to the recall document, the company didn't have FDA authorization to market the product. 

The suit, filed in Indiana’s Marion County Superior Court, names The Medical Licensing Board of Indiana and the Indiana Professional Licensing Agency, as well as several officials from those agencies, as the defendants.
