The Eighth Circuit recently concluded that there was no contractual basis to conclude that a pharmacy benefit manager agreed to class arbitration with four pharmacies because the agreement did not use the word “class” or refer to class arbitration in any way. The Court also rejected the pharmacies’ argument that there was “implicit authorization” for class arbitration because the pharmacies did not present any authority to support such a finding. The case is Catamaran Corp. v. Towncrest Pharmacy, et al., No. 17-3501, 2020 WL 110758 (8th Cir. 2020).
