Catamaran Corp. v. Towncrest Pharmacy, No. 16-3275 (8th Cir. 2017)Annotate this Case
A court must decide whether an arbitration agreement authorizes class arbitration. The Eighth Circuit held that the question of class arbitration belongs with the courts as a substantive question of arbitrability; questions concerning "whether the parties have submitted a particular dispute to arbitration" presumptively lie with the court; parties to an agreement may nonetheless commit the question to an arbitrator; and when dealing with class arbitration, the court sought clear and unmistakable evidence of an agreement to arbitrate the particular question of class arbitration. Accordingly, the court reversed the district court's order denying Catamaran's motion for summary judgment and remanded for further proceedings. On remand, the district court shall determine whether such a "contractual basis" for class arbitration exists in the agreements between Catamaran and the pharmacies.
