Commercial Litigation

  • Agricultural Litigation: Represented corn farmers, grain elevators and ethanol plants throughout the United States in claims against a leading multinational agricultural company.  In the first bellwether trial in the multidistrict litigation, a class of Kansas farmers obtained a $217.7 million jury, the 10th largest jury verdict that year. Following verdict, a $1.51 billion settlement on behalf of nationwide classes of corn farmers, grain handling facilities and ethanol production plants was reached
  • Whistleblower and Dodd Frank Act (DFA)/ Sarbanes Oxley (SOX) Executive Employment Litigation: Represented a senior corporate officer in Dodd Frank and Sarbanes Oxley claims against a Fortune 100 company.

  • Price Fixing: Represented a Fortune 500 company in Sherman Act claims against the largest producers of canned tuna in the country – Bumble Bee, Chicken of the Sea, and StarKist. The lawsuit alleges that these producers conspired to fix, raise, and maintain prices of canned and pouched tuna sold in the United States over a nearly 9-year period. The case was successfully resolved with Chicken of the Sea and continues against Bumble Bee and StarKist.
  • Refusal to Deal, Boycott: Represented startup company in an antitrust action against several race cars manufacturers and the industry’s sanctioning body. The plaintiff alleged that the defendants engaged in a long-running conspiracy to oust them the market for race cars in violation of the Sherman Act and the Kansas Restraint of Trade Act. A confidential settlement was reached with all defendants.
  • Price Fixing: Represented a Fortune 500 company in price fixing claims against the largest potato growers, shippers, and processors. The antitrust claims involved market participants efforts to control and reduce the supply of potatoes in order to raise and stabilize the prices at which potatoes were sold in the United States. The case involved novel issues of Capper-Volstead immunity and involved fighting on after direct and indirect class plaintiffs left the litigation. The case was settled favorably prior to trial.
  • Price Fixing / Supply Reduction: Represented a Fortune 500 company in Kansas State Court in antitrust claims brought under the Kansas Restraint of Trade Act. The lawsuit alleged that defendants engaged in illegal price fixing through coordinated efforts to reduce and stabilize the supply of eggs in violation of the Kansas Restraint of Trade Act, K.S.A. 50-101, et seq.  The case was successfully resolved after nearly four years of litigation.

  • Served as mediator in personal injury, products, and medical negligence cases.

  • Uber Sexual Assault Lawsuit: Represented a college student a lawsuit against Uber who was raped by her Uber driver. An investigation revealed that prior to the assault, the driver had been convicted of attempted murder and sentenced to 16 years in prison and other women had complained to Uber about the driver’s assaultive and harassing conduct. After more than 18 months of hard-fought litigation, the case was resolved to the mutual satisfaction of the parties.
  • Ride Sharing Service: Following trial in Jackson County Circuit Court, Steve obtained a $8.2 Million verdict for a sexual assault victim who sued her rider sharing driver assailant who had a violent criminal history. On June 14, 2019, a Jackson County, Missouri judge awarded the victim more than $8.2 million in damages that included $7.2 million in economic and non-economic damages for her “serious and permanent physical, emotional and personal injuries” and an additional $1 million in punitive damages. 
  • Propane Explosion: Represented seriously injured young man following a propane explosion in rural Kansas.  After several firms told the client he did not have a case against the propane supplier, we took the case, hired 5 experts, conducted discovery, and obtained a policy limits settlement against both defendants.  Our propane expert identified deficiencies in corroded system piping, non-compliance with the National Fuel Gas Code §54, the LP-Gas Safety Handbook (NPGA), and the National Propane Gas Association Certified Employee Training standards. Additional discovery uncovered the supplier’s continued refill of the propane system that contained an unsafe and recalled regulator.
  • Texting While Driving: Represented the surviving wife of a Missouri resident who was struck and killed in the crosswalk at 31st and Main, in Kansas City, Missouri by a driver who was texting.  Video evidence obtained from nearby KCATA buses showed the driver accelerated through the crosswalk, never braking before striking the pedestrian.  The case was filed in Jackson County Circuit Court and resulted in a $1.6 million policy limits settlement.
