Merrell Dow Pharmaceuticals Inc. v. Thompson, 478 U.S. 804 (1986), was a United States Supreme Court decision[1] involving the original jurisdiction of the federal district courts under 28 U.S.C. § 1331 (federal question jurisdiction).[2]
Background
The Thompsons, residents of Canada, and the MacTavishes, residents of Scotland, filed virtually identical complaints against Merrell Dow Pharmaceuticals in the Court of Common Pleas in Hamilton County, Ohio, claiming negligence, fraud, breach of warranty, and misbranding in violation of the Federal Food, Drug, and Cosmetic Act (FDCA). The mother in each family had taken the drug Bendectin during pregnancy which they claimed caused harm to their children including birth defects.
Procedural history
The case was filed in state court and then removed to federal district court where it was found that Count IV (the misbranding count) of the complaint alleged a cause of action arising under federal law and the motion to remand was denied.
