Representative/Recent Case Results

  • Plaintiff argued defendant engaged in a “Silent PPO” and unjustifiably reduced payments to the class through applying PPO discounts they did not deserve. The Southern District of Illinois court found that plaintiff’s claims for breach of contract, unjust enrichment, and ICFA violations were not subject to common proof, and therefore denied plaintiff’s motion to certify the class.
