Representative Matters:

  • Thomas Bonasera, Administrator of the Estate of Cecil McDaniel v. Richard Turiel:  tried to a defense verdict and protected judgment in the Court of Appeals of Ohio, Tenth Appellate District. Plaintiff brought a landlord negligence claim against the defendant alleging the defendant failed to maintain the premises and failed to maintain smoke detectors thereby causing the death of a tenant.
  • Jenkins v. James B. Day & Co., 69 Ohio St. 3d 541 (1994):  successfully defended a product liability wrongful death claim brought against the James B. Day Co. This product liability claim arises out of the death of a young woman and was based upon alleged inadequate written warnings accompanying the product. The young woman allegedly inhaled methylene chloride. The case was originally dismissed on summary judgment and ultimately appealed to the Ohio Supreme Court, which held that the Federal Hazardous Substance Act, which governed the subject product, provided a limited preemption of state law in the area of labeling of hazardous substances. On remand the case was tried to a defense verdict.
  • Remington v. Triplett:  summary judgment granted in the Court of Common Pleas and upheld in the Court of Appeals of Ohio, Fifth Appellate District, in favor of defendant, The Cincinnati Insurance Company. The court found the insured expressly and knowingly rejected UM/UIM coverage and therefore The Cincinnati Insurance Company had no obligation to provide such coverage.
  • Wolfe v. HER, Inc.:  successfully defended in trial, breach of contract claims, negligence claims, and punitive damage claims brought by plaintiff against defendant HER, Inc. and defendant real estate property manager.
  • Gallihugh v.
