  • Graneros Unidos S.A. de C.V. v. GSI Group, LLC et al. – Defended GSI Group at trial in the U.S. District Court in Urbana, IL, in a case related to the sale of eight-grain bins and other equipment by GSI Group to a Mexican grain company, Graneros Unidos S.A. de C.V. The grain bins were destroyed during Hurricane Lane in September of 2006. The plaintiff claimed the bins were destroyed by winds below the wind rating promised in the contract, that the bins were negligently designed, and that fraudulent misrepresentations and concealments were made during the transaction. The claimed damages included $2.4 million in damaged property, $2.5 million in lost grain, and $5 million in lost profits. There were also claims for punitive damages and attorneys' fees under the Consumer Fraud Act claim. The trial was bifurcated, and the jury returned the verdict in favor of firm client GSI on the breach of contract and negligence claims. The judge subsequently ruled in favor of defendant GSI on the Consumer Fraud Act and punitive damages claims.
  • Corn Belt Energy v. Schick, Circuit Court, DeWitt County, Illinois – Represented Corn Belt Energy in a jury trial regarding a subrogation claim to recover Workers' Compensation benefits paid to a Corn Belt employee. The case was related to an injury sustained by a Corn Belt lineman who had been working on a utility pole project on a country road. The defendant, a local farmer, was driving a truck towing a large farm implement known as a Crumbler, which struck the lineman. The parties stipulated the amount of the damages, and the jury returned a verdict finding the defendant farmer 80% at fault for the accident.
  • Dunn v. B&O Railroad – Successfully upheld the duty of care for motorists in connection with a railroad crossing/wrongful death case and upheld the strict definition of that duty of care following the adoption of comparative negligence by the Illinois Supreme Court.
  • Walker v. Casey's Retail Co., Circuit Court, Iroquois County, Illionois – Defended a premises liability jury trial for Casey's General Store. The plaintiff was injured walking into a Casey's General Store when she pulled the door onto her foot and crushed her left fourth toe. She subsequently received treatment from a podiatrist for Morton's neuroma and other left foot conditions. Prior to trial, the court granted summary judgment for Casey's on the claim of specific negligence but denied summary judgment as to the plaintiff's separate res ipsa loquitor count. At the jury trial, the testimony of the podiatrist was barred because the plaintiff failed to establish causation for the medical conditions diagnosed. After a short deliberation, the jury returned a defense verdict in favor of Casey's.
