Successfully Overturned $1.8 Million Judgment on Appeal in New Jersey
Appellate Advocacy & Post-Trial Practice
Insurance Services - Coverage & Bad Faith Litigation
July 11, 2025
We successfully overturned a $1.8 million judgment on appeal in a case that involved the Laidlow exclusion in a workers’ compensation/employers liability policy. The decedent succumbed to heat exhaustion while at work, and the plaintiff alleged the death was due to working conditions the employer knew were substantially certain to lead to injury. Our client, the insurer, offered to defend the employer, but only to the extent of obtaining dismissal of the workers’ compensation claim, which was filed in the wrong forum.

Marshall Dennehey’s trial and appellate attorneys were successful in their representation of a national home improvement retail corporation’s tool and truck rental division.

At the trial level, the judge granted our motion for a directed verdict and dismissed the case. The plaintiff had rented a flatbed truck in 2018 to move a cabinet he had just purchased.
Summary Judgment Secured in a Complex Medical Malpractice Case
Health Care Liability
May 2, 2024
We obtained summary judgment on behalf of an obstetrician in a medical malpractice action. The plaintiff alleged that our client did not obtain the requisite informed consent from the plaintiff to undergo a trial of labor after having two prior cesarean section deliveries (TOLAC x2). The court found that the plaintiff’s lack of informed consent claim was without foundation as she had an awareness of the risks of TOLAC x2.
