   U.S. Court of Appeals Case No:  19-2645
   U.S. District Court for the Western District of Missouri - Kansas City   
   [PUBLISHED] [Erickson, Author, with Loken and Benton, Circuit Judges] 
   Civil case - Class Actions. In action alleging defendants' marketing of 
   their premium pet foods violated the Missouri Merchandising Practices Act, 
   Missouri antitrust laws and Missouri unjust enrichment law, the district 
   court erred in remanding the matter to state court for lack of subject 
   matter jurisdiction; plaintiffs rely explicitly on federal law throughout 
   their pleadings, and their prayer for relief invokes federal jurisdiction 
   because it seeks injunctive and declaratory relief that necessarily 
   requires the interpretation and application of federal law, including the 
   Food Drug and Cosmetic Act; as a result, based on the allegations of the 
   complaint and the relief sought, a federal issue surrounding the state law 
   claims is necessarily raised, actually disputed, substantial and capable 
   of resolution in federal court without disturbing the federal-state 
   balance approved by Congress.
