Representative/Recent Case Results

  • Secured defense verdict in trial involving personal injury in automobile collision case. Plaintiff had asked for pain and suffering damages of $100,000 to $200,000. Instead, jury returned unanimous verdict that Plaintiff was completely at fault. [Jane Kapp v. James Steingrandt and JDS Cattle Company, Ltd.; No. 4:20-cv-00221-JAR (E.D. Mo. 2021)]
  • Secured summary judgement for client in case where plaintiff sued for personal injuries following hand amputation while operating machinery as part of his employment. The part manufactured by client was not defective and was not designed specifically for use in the machine at issue. Therefore, court found defendant was entitled to summary judgement. (Missouri law, does not impose liability on the manufacturer of a non-defective component part when the end product was designed, assembled, and sold by other entities.) [Timothy Farkas v. Overton Industries, Inc., et al.; No. 4:17-CV-761 RLW (December 2018)]
  • Secured summary judgment for client in case where plaintiffs alleged damage to their multimillion-dollar home arising from the design and installation of an inadequate heating and cooling system in their indoor poolroom. Plaintiffs sought damages based on the alleged breach of contract to perform punch list work at the home after the design and installation of the system occurred. Because the contract at issue expressly disclaimed any liability for work done prior to its execution, and because the undisputed material facts demonstrated that the system was designed and installed in the home prior to that date, the Court found defendant was entitled to summary judgment. [Harold Lewis, et al. v. Sigman Indoor Climate Solutions, et al., St. Charles County, Missouri Circuit Court; No. 1711‑CC00994]. Summary judgement affirmed upon appeal. [Harold Lewis, et al. v. Sigman Indoor Climate Solutions, et al., St. Charles County, Missouri Circuit Court; No. 1711‑CC00994, ED 106899]
  • Secured summary judgment for client in case where plaintiff sued co-employee for plaintiff’s workplace injuries. Judgment was affirmed by Missouri Supreme Court, which found co-employee’s negligence was result of breach of employer’s nondelegable duty to provide a safe workplace; thus, negligence was the employer’s, not the co-employee’s. [Matthew Fogerty v. Larry Meyer, Missouri Supreme Court No. SC96030] Ruling in case changed Missouri law regarding co-employee liability and when one co-employee may sue another.
  • Secured summary judgment for client in case where plaintiff attempted to set forth claim of negligence based on client’s alleged failure to ensure plaintiff’s safety or the structural integrity of a stairwell; court found client owed no legal duty to plaintiff and that the condition of the stairwell was open and obvious as a matter of law. [Joseph Moore, et al. v. Burton Brothers General Contractors, et al., City of St. Louis, Missouri Circuit Court; Case No. 1422-CC08898 (November 29, 2017)]
