Cal$-$Ban $2010$ is a weight loss drug made by We Care Products, Inc., a Florida corporation, and marketed through RSA Industries, another Florida corporation. Enticed by ads for Cal$-$Ban that she saw on social media, Dan Tucker's wife purchased the drug for her husband by accessing a website maintained by Cal$-$Ban, clicking on a picture of the product and completing an online form about shipping and credit card information. Within a week of starting to use the product, Tucker suffered a ruptured colon. Alleging that the injury was caused by Cal$-$Ban, Tucker sued Preston's Pharmacies, RSA, and We Care Products in a Tennessee state court. RSA and We Care argued that Tennessee did not have personal jurisdiction over them because RSA and We Care were Florida corporations. Also, they argued that if Tennessee did have personal jurisdiction, the appropriate court was the federal district court.
