  • Obtained favorable opinion from the Illinois Appellate Court, Fifth District. This case, a matter of first impression in Illinois, involved National Bank Act Preemptions and the application of the Riegal Niel Act and Illinois State Parity statutes to an out-of-state bank. It was the first and only case of its kind in Illinois. [Johnson v. First Bank, 382 Ill.App.3d 907, 89 N.E. 2d 233, 321 Ill. Dec. 329 (5th Dist. April 18, 2008)]
  • Successfully argued against class certification. Plaintiff argued defendant engaged in a “Silent PPO” and unjustifiably reduced payments to the class through applying PPO discounts it did not deserve. The Southern District of Illinois court found that plaintiff’s claims for breach of contract, unjust enrichment, and ICFA (Illinois Consumer Fraud Act) violations were not subject to common proof and therefore denied plaintiff’s motion to certify the class. (Roche v. Zenith)
  • Part of trial team that successfully defended nationwide class action jury trial in St. Clair County, Illinois. Verdict was affirmed on appeal. (Craft v. Allstate)
  • Part of trial team that successfully represented Zimmer, Inc. in multiple jury trials in St. Clair County, Illinois. All trials ended in defense verdicts. (Santas v. Zimmer, Inc.)
  • Successfully defended a Class Action Fairness Act removal, including before the United States Court of Appeals for the Seventh Circuit. [Spivey v. Vertrue, 528 F.3d 982 (7th Cir. 2008)]
