Representative Matters
  • Wayne Bagley et al. v. Wyeth Holdings Corporation (SC 19835). In 2017, Katie successfully argued an appeal before the Connecticut Supreme  Court.   The Supreme Court agreed with Katie that at trial the plaintiff failed to prove through admissible expert testimony  that her client’s product was the proximate cause of the plaintiff’s injury.   The Supreme Court  reversed the judgment and remanded the case with direction to grant the defendant’s motion to set aside the verdict and for judgment notwithstanding the verdict.   [Bagley Connecticut Decision].
  • Ronald Dummitt and Doris Kay Dummitt v. Elliott Company. On August 17, 2011, after a nine week trial before Judge Joan A. Madden in the Supreme Court of New York, County of New York, a jury returned a verdict in favor of the Plaintiffs. The jury found Elliott Company, AP&S' client, only 1% responsible. Plaintiffs alleged that Mr. Dummitt developed cancer as a result of exposure to asbestos while working in the United States Navy as a boiler technician from 1960 to 1977. As counsel for Elliott Company, Katharine argued that Elliott Company did not manufacture, supply or specify any of the asbestos-containing products at issue and did not breach any duty to warn.
  • Kenneth Balthazar and Sandra Balthazar v. Foster Wheeler Energy Corp. On June 1, 2007, after a five-week trial, a Suffolk County jury returned the first Massachusetts defense verdict in an asbestos personal injury lawsuit in over 10 years. As co-counsel for Foster Wheeler, Katharine argued that her client did not breach any duty to warn Mr. Balthazar, who suffered from cancer resulting from asbestos exposure, of potential asbestos hazards in boilers supplied by Foster Wheeler for a Navy destroyer in 1949, and jurors concurred.
