   U.S. Court of Appeals Case No:  16-3275
   U.S. District Court for the Southern District of Iowa - Des Moines   
   [PUBLISHED] [Shepherd, Author, with Smith, Chief Judge, and Fenner, 
   District Judge] 
   Civil case - Arbitration. In a case of first impression in this circuit, 
   the court holds that a court, rather than an arbitrator, must decide 
   whether an arbitration agreement authorized class arbitration; the 
   question of class arbitration is substantive in nature and requires a 
   judicial determination, and the district court erred in determining the 
   issue was procedural; even though the question of class arbitration lies 
   with the courts, parties to an agreement may nonetheless commit the 
   question to an arbitrator; however, to do so, the parties' agreement must 
   clearly and unmistakably delegate the question to the arbitrator; on 
   remand, the district court should determine whether a contractual basis 
   for class arbitration exists in the parties' agreements. See Stolt-Nielsen 
   S.A. v. AnimalFeeds Int'l Corp. 559 U.S. 662 (2010).
