  • Assisted in securing a unanimous 6-0 defense verdict in a New Jersey premises liability case after the jury found no negligence on the part of the defendant. The plaintiff alleged that a six-foot drill bit fell from a retail display, causing a concussion, post-concussion syndrome and permanent cognitive impairments. The defense demonstrated that the item was displaced only after an unidentified customer struck the shelving with a shopping cart and that there was no evidence store employees knew or should have known of the condition. Through surveillance video, fact witness testimony and expert evidence, the defense also established that the impact was inconsistent with the forces necessary to cause a concussion and highlighted alternative explanations for the plaintiff's claimed injuries. Following a six-day trial, the jury returned a complete defense verdict, finding the defendant was not negligent.

    Secured a unanimous defense verdict in a premises liability matter involving a national home improvement retailer. The plaintiff alleged that she developed Complex Regional Pain Syndrome (CRPS) following a fall in the retailer's parking lot in October 2022. Plaintiff claimed that the incident necessitated significant ongoing medical treatment, including the implantation of a permanent spinal cord stimulator. The plaintiff sought substantial damages, including claims for extensive future medical care. The defense team successfully challenged the credibility of the plaintiff's allegations and expert testimony through rigorous cross-examination and the presentation of defense experts in forensic engineering, human factors, and pain management. The defense also demonstrated that the plaintiff's alleged condition was attributable to pre-existing medical issues rather than the incident at issue. Following a six-day trial, the jury deliberated for just 42 minutes before returning a unanimous verdict finding no negligence on the part of the defendant.

    Secured a no-cause verdict on behalf of a national home improvement retailer in a personal injury action. The plaintiff alleged that on May 20, 2019, she was injured at one of the retailer’s stores when an associate moved a lumber cart, causing a PVC pipe to fall and strike her head and right shoulder. She claimed permanent traumatic brain injury, concussion, and spinal injuries, supported by her orthopedic and neurologic experts. Our defense orthopedic and neurologic experts testified that the plaintiff’s reported symptoms were more consistent with malingering or a somatoform disorder. After a one-week trial and approximately 45 minutes of deliberation, the jury unanimously found the defendant was not negligent. The last demand was $1.2 million, and the final offer was $100,000.

    Obtained summary judgment in favor of an automobile liability insurance carrier, wherein court upheld carrier's disclaimer of defense and indemnity coverage to its insured in response to personal injury lawsuit brought against insured arising from motor vehicle accident on the basis that insured had made material misrepresentations on his insurance policy application as to where he resided and principally garaged the insured vehicle.

    Successfully represented an insurance carrier in a declaratory judgment action, wherein carrier disclaimed coverage to insured under an automobile liability insurance policy with regard to an underlying personal injury lawsuit brought against insured arising from a motor vehicle accident because insured failed to provide the carrier with notice of either the accident or the resultant lawsuit and which, in turn, substantially prejudiced the insurer.

    Obtained summary judgment on behalf of defendant employers and having all claims against them dismissed in civil lawsuits brought against them by their own employees for injuries the employees sustained in the workplace on the basis that there was no evidence to support a finding that the "intentional wrong" exception to the workers' compensation bar applied. In one of these cases, in particular, after successfully in having the plaintiff employee's claim against his employer dismissed, the employee continued to litigate his claim against the remaining defendant, a forklift manufacturer, resulting in a jury verdict in favor of the plaintiff in excess of $1 million, which was subsequently affirmed on appeal.

    Obtained summary judgment in favor of a commercial general liability carrier in a declaratory judgment action, successfully limiting the CGL carrier's potential liability exposure in a case involving serious injuries to two plaintiffs as a result of a robbery. Received a favorable ruling from the court that the $100,000 aggregate policy limit, set forth in the CGL policy's Assault & Battery Endorsement, was the applicable liability coverage limit potentially available to the injured plaintiffs under the CGL policy and not the $1 million per occurrence coverage limit, set forth in the policy's Declarations, as was argued by the plaintiffs.

    Successfully defended a CGL insurance carrier in a claim brought against it by the landlord/owner of a warehouse for defense and indemnity coverage as an Additional Insured under a CGL insurance policy issued by the carrier to one of the tenants at the warehouse in a high-exposure property damage loss case arising from a fire on the basis that the landlord did not qualify as an additional insured on the policy pursuant to the Additional Insured Endorsement and the landlord's claim should be a claim against its insurance broker for professional negligence in not procuring the proper insurance coverage requested by the landlord.

    Obtained summary judgment in favor of a subcontractor on an indemnity cross-claim, where the contract at issue, between the subcontractor and the general contractor, did not include the required express language that the general contractor would be indemnified for own negligence.

Summary Judgment for Insurer in Complex Coverage Case

We successfully persuaded the court to grant summary judgement on behalf of a major insurer on a complex coverage issue. This coverage case concerned two Virginia personal automobile policies in regard to an automobile accident in New Jersey. The son of a divorced couple sought coverage for an accident he was involved in on a major thoroughfare in New Jersey. At the time of the accident, the son was operating a motor vehicle owned by another Virginia resident, and he had the reasonable expectation that he had permission to operate the vehicle. The accident was very serious, and he sought coverage under both of his parents’ policies. As to the mother’s policy, we convinced the court that the son was not an insured under her policy because he was not so designated on the policy’s declaration page, which was a specific condition of the policy pursuant to Virginia law. As to the father’s policy, once again, we convinced the court that the son was not an insured under this policy given the fact that the mother had sole and exclusive custody under the divorce agreement; thus, the son was not a resident relative of the father’s household. Therefore, neither policy provided coverage for the son, and the insurer was totally dismissed from the case.

Court Agrees Mode of Operations Does Not Apply in Retail Liability Case

We were successful on a motion for summary judgment, thereby barring the application of the mode of operations in a slip and fall case where an alleged partially eaten sandwich was found in the aisle of the retailer. ​The facts indicated that the sandwich came from a fast-food sandwich shop within the premises and was dropped by an unidentified customer, who took the item to go and dropped it in the aisle before the plaintiff fell. The court ruled that the mode of operations did not apply because the aisle, which contained greeting cards and the like, and did not create an extension of the cafeteria within the retailer’s premises. Further, the court ruled there was no nexus to any self-serve component of the fast food restaurant’s business to the area in the retailer’s store proper where the accident occurred.

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.

Featured Conversations... Key Takeaways from A.M. Best’s Webinar on the Misuse Defense in Product Liability Claims, Featuring Michael Salvati

Michael Salvati, shareholder in our Philadelphia office, was a panelist for the April A.M. Best webinar, “The Misuse Defense: Strategic Approaches to Defending Product Liability Claims for Insurers.” During the program, Michael and his fellow panelists offered practical, jurisdiction‑specific guidance on how misuse and failure‑to‑warn theories intersect in modern product liability litigation. Michael emphasized the unique challenges these claims present—particularly in states like Pennsylvania, where evidentiary rules diverge sharply from those applied in many other jurisdictions. Failure to Warn as the “Flip Side” of Misuse Salvati explained that failure‑to‑warn allegations often arise as a direct counter to a misuse defense. As he noted, “If our misuse defense is that the plaintiff didn't use a product properly or safely, then the failure to warn claim is that we didn't tell them how to use it properly.” He emphasized that these claims can stem from either the absence of warnings or criticisms of existing warnings, such as insufficient specificity or lack of clarity about risks. Pennsylvania’s Unique Evidentiary Landscape One of Salvati’s most notable points was the stark difference in how Pennsylvania treats evidence of compliance with industry standards. He highlighted that Pennsylvania is “one of the only states…where that evidence is not admissible” in strict liability cases. Manufacturers cannot rely on compliance with ANSI, UL, ISO, or even federal safety standards to defend the product against a strict liability claim—because the focus is solely on the product itself, not the manufacturer’s conduct. Salvati acknowledged the challenge this creates for defense counsel and clients who expect such compliance to carry weight. Understanding the Three Defect Theories Salvati also walked through the three primary defect theories recognized in many jurisdictions: - Design defect – a flaw in the product’s intended design - Manufacturing defect – a deviation affecting a specific unit - Failure to warn – inadequate instructions or warnings He noted that warnings claims are increasingly significant and sometimes stand alone when design or manufacturing theories are weak. As he put it, plaintiffs often default to warnings claims because “the default position seems to be, ‘If I got hurt, there must be something wrong.’” Warranties and State‑by‑State Variations Salvati addressed how breach‑of‑warranty claims fit into the broader framework, explaining that implied warranties—such as merchantability—often overlap with strict liability in Pennsylvania. He emphasized the importance of understanding local nuances, as warranty law and admissibility rules vary widely across states. Looking Ahead: The Growing Importance of Warnings In his closing remarks, Salvati stressed that warnings should never be treated as an afterthought in product liability defense. He observed that warnings‑only claims are becoming more common and urged manufacturers and insurers to continually evaluate the clarity and completeness of their instructions and warnings. His takeaway: “We should always be talking about what are the instructions that come with our products…to bolster a misuse defense.” Listen to the complete webinar here: https://www3.ambest.com/conferences/events/eventregister.aspx?event_id=WEB1074.

Legal Update for Special Education Law: Recent Positive Outcomes From the Group

Hearing Officer Confirms District Acted Appropriately Under IDEA and Section 504 William J. McPartland (Scranton) obtained a finding in favor of our client, a school district, on all issues following a due process hearing. The parent had filed a due process complaint alleging that the school district had breached its child find duty under the IDEA and Section 504, that the school district had discriminated against the student on the basis of disability in violation of Section 504, and that the school district had denied a free and appropriate public education to the student both by developing inadequate IEPs and via an actionable procedural violation.  Specifically, the student had received a Section 504 evaluation in October 2023, after a number of behavioral infractions culminating in a fight in September 2023, was identified as having anxiety and a sleep disorder, and received appropriate Section 504 accommodations. The student had never previously demonstrated signs of a learning disability, and the parent denied the school district permission to evaluate the student for special education needs in November 2023, and January 2024. The parent granted the district permission to evaluate the student in October 2024, after a private psychologist diagnosed the student with Attention Deficit Hyperactivity Disorder, possible Oppositional Defiance Disorder, a learning disorder, and anxiety. The school district issued a special education evaluation report in December 2024, finding that the student had an emotional disturbance and other health impairment, and an IEP providing an itinerant level of emotional support, as well as instruction in academics and social skills, was issued in January 2025, and amended in February, March, and April 2025. The student withdrew from the school district in April 2025, to attend a cyber charter school. The hearing officer determined that the school district had not violated its child find duty to the student in violation of either the IDEA or Section 504 where the district developed a Section 504 plan for the student within a month and a half of the parent’s first request for a Section 504 evaluation and where the parent repeatedly denied consent to conduct an IDEA evaluation of the student. The hearing officer noted that the student’s sporadic record of behavioral infractions prior to September 2023, did not suggest that the student had a disability prior to the parent’s initial request for an evaluation. The hearing officer further determined that no evidence had been produced to suggest that the student was discriminated against on the basis of disability in violation of Section 504. Additionally, the hearing officer determined that the IEP offered to the student was substantively adequate and that, to the extent the social and emotional programming offered by the school district was not received by the student, this resulted from the parent’s refusal to accept the same. The hearing officer finally determined that the school district did not commit an actionable procedural violation by delaying development of an IEP for the student where the parent repeatedly denied consent to evaluate the student. Court Dismisses Three of Four Claims Against School District Christopher J. Conrad and Daniel P. McGannon (Harrisburg) achieved a significant early victory on behalf of a school district client in. The team successfully obtained dismissal of three of the four claims asserted in the plaintiff’s amended complaint. The former district superintendent brought multiple claims arising out of his alleged “forced resignation,” including age discrimination under the ADEA, a Section 1983 Equal Protection claim, a Pennsylvania Whistleblower claim, and breach of contract. On behalf of the district, the defense team moved to dismiss the complaint in part, arguing: The plaintiff failed to plead sufficient facts to support a prima facie case of age discrimination. The equal protection claim was barred because the ADEA provides the exclusive federal remedy for age-based employment claims. The breach of contract claim could not stand because the underlying employment agreement had expired prior to the alleged breach. The court agreed, dismissing the ADEA, equal protection, and breach of contract claims in their entirety. As a result, only a single claim under the Pennsylvania Whistleblower Law remains pending. This outcome substantially narrows the scope of the litigation and positions the client for a more efficient defense moving forward.
