Summary Judgment Obtained in a Premises and Product Liability Case

We won a motion for summary judgment in Schuylkill County, PA, in a premises liability and product liability case. We represented the manufacturer of a concrete railroad crossing that was installed at an intersection in 2005. In 2021, the plaintiff was riding his bike across the crossing when his bike tire allegedly became stuck in a gap in the concrete. There was ample evidence that the railroad was responsible for inspecting and maintaining the crossing while our client did nothing other than supply the prefabricated crossing. We argued the gap that developed in the crossing was not the responsibility of the crossing manufacturer and that the statute of repose barred the lawsuit. The court agreed and granted summary judgment in favor of the manufacturer.

Successfully Defended Appeal Sustaining Objections of Improper Venue

We successfully defended the plaintiff’s appeal of a trial court decision sustaining preliminary objections on the grounds of improper venue. This case involved the death of a 19-year-old woman at a university who fell down an 11-story trash chute in an off-campus condominium building. In this mixed negligence and product liability case, we represented two of the multiple defendants, the condominium association and the building management company. The Philadelphia Court of Common Pleas found that venue was improper in Philadelphia County and ordered that the case be transferred to Centre County. The plaintiff appealed that decision, and the matter was briefed and argued in the Superior Court of Pennsylvania. The Superior Court, in a precedential decision, affirmed the trial court’s decision and found that there was no abuse of discretion in sustaining the preliminary objections. In support of its decision, the Superior Court found that the plaintiff’s arguments were unsupported by Pennsylvania law. The Superior Court, in finding waiver of an issue, quoted directly from the brief prepared by Kim.

Superior Court Clarifies Crashworthiness Doctrine and Provides Key Jury‑Instruction Guidance

April 1, 2026

In the much-publicized Amagasu case, a jury returned a verdict of nearly a billion dollars to a plaintiff who was paralyzed in a rollover car accident.  On appeal, the Superior Court vacated the award and remanded for a new trial stating that the trial court did not properly charge the jury on crashworthiness principles. Crashworthiness is a subset of products liability cases in which it is alleged that a vehicle possessed a defect that did not cause an accident, but did not offer sufficient protection to the vehicle’s occupant during the accident. Pennsylvania law recognizes that collisions and other accidents are part of the intended use of a motor vehicle, so manufacturers must design and manufacture a product that is “reasonably crashworthy.” For example, if a plaintiff is involved in a head-on collision and the air bags do not deploy, the lack of air bag deployment did not cause the collision, but possibly increased the severity of the plaintiff’s injuries –  that failure to perform may give rise to a product defect claim. In Amagasu, the Superior Court re-affirmed the elements of a crashworthiness claim, which was first recognized in Pennsylvania in 1994, but has not frequently been analyzed since the landmark Tincher case re-defined the product liability cause of action. Amagasu explained that crashworthiness cases involved a “more rigorous” and a “heightened burden of proof” compared to ordinary products liability cases as a trade off for expanding the scope of liability to an alleged defect that did not cause the underlying accident. Specifically, in addition to proving a product defect, the plaintiff must prove that, at the time the vehicle was designed, a safer and more practical design existed. A plaintiff’s burden to prove causation is also heavier in a crashworthiness case, as he or she must distinguish between the “enhanced injury” caused by the defect, and the “non-compensable injuries” he or she would have sustained in the accident anyway. The Superior Court emphasized that these crashworthiness elements “impose a burden of proof far and above that of a typical” products liability case. Amagasu may have a greater impact than simply crashworthiness cases as the billion-dollar verdict was vacated because the trial court did not give proper jury instructions. The trial court had avoided giving instructions that were not included in the Pennsylvania Suggested Standard Civil Jury Instructions, which did not provide a specific instruction on crashworthiness. The Suggested Standard Jury Instructions are an excellent resource and guide, but they are not an exhaustive statement of every area of the law. If a legal issue is raised by the evidence, the jury must be given an appropriate instruction, even if one is not included in the SSJI.

In One Fell Swoop, Federal Court Clarifies Pleading Standards for Product Misuse Defense

January 1, 2026

Thomas Donnelly brought suit in Greene County, Pennsylvania, against Defendants, General Electric Company and Joenic Steel, LLC, claiming he was injured while participating in the lift of a specially fabricated expansion joint. The plaintiff’s claims sounded in negligence, strict product liability, and breach of warranty. General Electric properly removed the case to the Western District of Pennsylvania based on diversity jurisdiction. Both defendants raised the affirmative defense of product misuse, pursuant to Reott v. Asia Trend, Inc., 55 A.3d 1088 (Pa. 2012), which held that “a defendant in a Section 402A action must plead and prove, as an affirmative defense, that the plaintiff acted in a highly reckless manner, if such conduct is asserted.” However, the words used in each defendants’ responsive pleadings were significantly different. In particular, Joenic Steel pled that the “plaintiff may have failed to exercise that degree of care and caution requiring attempting to assist in lifting a section of the expansion joint, and as such, the plaintiff’s injuries and damages were due to the conduct and actions of the plaintiff,” and that the “plaintiff assumed a known risk of harm by engaging in the means, methods and manner by which the expansion joint was being erected, and as such, Joenic Steel, Inc. cannot be found liable to the plaintiff.” Conversely, General Electric pled, among other things, that the “plaintiff’s claims against defendant GE are barred to the extent plaintiff’s conduct was the sole cause of the alleged incident,” and that the allegedly defective condition of the product “may have been the result of misuse, abuse or neglect, or substantial alteration, modification and/or change in the product between the time it left the custody, possession and/or control of defendant GE.” Donnelly moved for summary judgment on both of the defendants’ product misuse defenses. Judge Horan granted the plaintiff’s motion as to Joenic Steel but denied the motion as to General Electric based on the language that each defendant used in pleading the defense. In particular, Judge Horan found that Joenic Steel’s pleading failed to plead either product misuse or highly reckless conduct as mandated under Reott, while General Electric’s pleading stated both terms “misuse” and “sole cause,” thereby properly preserving the defense. Accordingly, the court found that Joenic Steel waived its defense of product misuse, while General Electric was permitted to proceed on the theory. This case highlights that answers to complaints are neither boilerplate nor form documents, and that words matter. It is clear from Joenic Steel’s pleading that it intended to pursue a product misuse defense, but by failing to use the specific words required in Reott, the legitimate and dispositive defense was deemed waived. Pleading requirements, especially in federal court, cannot be taken lightly. Attorneys must take extra care to follow them at all times or risk waiving important defenses for their clients.

What’s Hot in Workers’ Comp - News and Results*

RESULTS* Ben Durstein (Wilmington) obtained a favorable decision involving a claimant who fractured his patella in a work accident requiring two surgeries. The IAB rejected the claimant’s medical expert’s opinion that he sustained a 25% permanent impairment to the right lower extremity. Instead, the board accepted the opinion of the employer’s medical expert that the appropriate permanency was 13% utilizing the 6th Edition of the AMA Guides to the Evaluation of Permanent Impairment. Tony Natale III (King of Prussia) successfully had a claim petition alleging new injuries and periods of disability dismissed based on full recovery. The claimant was injured when his skid loader was struck by another loader in the process of baling hay. Original injuries were accepted and the claimant returned to work. Thereafter, the claimant abandoned work and filed a claim petition to assert new injuries and extended disability. Cross examination of the claimant’s medical expert stunningly revealed his failure to review claimant testimony, his lack of awareness of a social security disability decision detailing the existence of claimant’s alleged work-related conditions prior to the date of work injury, and his failure to understand that the claimant admitted to full recovery of injuries for which he was continuing to treat. Tony Natale III (King of Prussia) successfully obtained a defense verdict in a Medicare conditional payment lien third level appeal. The United States government alleged a Medicare conditional lien payment was due and owing in the upper six-figure range based on an auto accident and PIP policy for which the government conditionally became the primary carrier. The government argued that our client, the PIP carrier, was the primary payer and, under federal law, must reimburse the government for its conditional lien payment. At the third-level appeal hearing, the government’s position was refuted by the revelation that the date of injury tied to the medical bills associated with the lien was glaringly and chronologically prior to the insurer’s PIP policy date. The court held that based on this evidence and argument, the government could not meet its requirements to assert a lien against our client. A. Judd Woytek (King of Prussia) and John Abda (Scranton) successfully had a workers’ compensation claim petition granted for medical benefits only for a closed period with no wage loss awarded. The claimant alleged multiple injuries as the result of a very minor motor vehicle incident where a co-worker’s delivery van rolled down an incline of approximately six feet, and bumped into the rear of the claimant’s delivery van. He claimed he was thrown forward and suffered head and neck injuries, along with aggravating a pre-existing ankle injury. The claimant was also terminated following the accident for having a large hunting knife in his van, which was against the employer’s workplace violence policy. The judge granted the claim for a mild concussion and an ankle contusion, but terminated medical benefits as of the date of our IME’s. The judge found that no wage loss benefits were payable as the claimant was terminated for cause and work remained available to him. The judge found our medical experts to be more credible than the claimant’s, along with finding our four employer witnesses to all be credible. The trial team was assisted by paralegal Bonnie Zemek (King of Prussia). Eric Scott Thompson (Wilmington) was successful in a workers’ compensation matter in Delaware. On October 15, 2024, the claimant was injured while performing fire training in a multistory building when he tripped over a fire line, injuring his right knee. The claimant received regular and consistent treatment for the right knee through August 29, 2025, when he presented with left knee complaints for the first time. His treating orthopedist diagnosed a hamstring strain. The claimant was next seen October 15, 2025, with continued left knee complaints, and was referred to a total knee doctor within the practice. He was then diagnosed with a posterior root tear of the medial meniscus. Our expert testified that it was not plausible for a lateral hamstring strain to progress to a meniscal tear in two months. The claimant required a total knee replacement that was ultimately performed in February 2026. In the six months between the time of initial presentation with left knee complaints and the total knee replacement, conservative care consisted of a single injection. Our expert testified that posterior root media meniscal tears can respond to conservative care, and it was not known if it would with the claimant because it was not adequately explored. The Industrial Accident Board agreed with our expert and determined that the claimant failed to meet the burden of establishing more likely than not that the left knee complaints were caused by overloading/overuse as a result of the compensable injury to the right knee. They also agreed that the claimant was able to return to work in a sedentary capacity as opined by his physicians and our expert prior to the left total knee replacement and that there were employment opportunities available within his restrictions and capabilities as presented by the vocational expert. As a result, the claimant was no longer entitled to total disability benefits and will receive partial disability benefits for which he is limited to 300 weeks. Michele Punturi (Philadelphia) and Alana Staniszewski (Pittsburgh) had a termination petition granted in a Pennsylvania workers’ compensation case. The petition involved an echocardiography technologist with long-term employment at a local hospital who sustained a right shoulder injury resulting in surgery in January 2024. Following surgery, the claimant was diagnosed with a frozen shoulder and underwent additional surgery in June 2024, with a recommendation for a third surgery. The opinions of the defense medical expert, a Board-certified orthopedic surgeon, were found credible, persuasive, and competent based upon the extensive history he obtained from the claimant, analysis of the mechanism of injury, and review of records, along with comparison of MRIs from October 2023, February 11, 2024, and January 6, 2025, which failed to reveal any causal relationship other than a strain/sprain of the right shoulder. This evidence supported that the claimant had fully recovered, and was not in need of any ongoing medical treatment and/or restrictions. In particular, despite allegations of injuries beyond a sprain/strain, the defense medical expert identified that those allegations were not consistent with what was found at the time of surgery, and elements of the surgery were to treat a chronic and degenerative condition. Additionally there were no ongoing issues or problems with the subscapularis, which was intact, consistent with the follow-up MRI of February 11, 2024, and the claimant did not have evidence of a frozen shoulder. In fact, the MRIs and mechanism of injury, he opined, did not support any injury causing tendonitis or inflammatory conditions within the bicep tendon. Furthermore, multiple days of surveillance footage demonstrated the claimant’s normal use, with the ability to sweep and shovel snow, operate her vehicle, raise her arms above shoulder level, and use a broom – all without any observable difficulty, which challenged the claimant’s credibility of a disability and further established a lack of causation. As a result of this favorable decision, supersedeas fund reimbursement will be obtained for both wage loss and medical benefits through the supersedeas fund recovery process. *Prior Results Do Not Guarantee a Similar Outcome NEWS Heather Carbone (Jacksonville) was a panelist for a webinar hosted by The Workers’ Compensation Claims Professionals (WCCP) Association. As part of the “Meet the Experts” Series, the speakers addressed “Afterthoughts that Undermine a Successful Mediation,” highlighting the pitfalls and challenges of underprepared or unprepared mediation participants. The discussion included appropriate pre-mediation communications, setting of expectations, management of expectations, and working through the unexpected or unprepared. Attendees gained ideas about how and when to prepare, best practices, and the potential for non-parties (spouse, significant other, risk owners-insurers) to have differing perspectives or concerns than the actual employee and employer. On May 21-22, 2026, A. Judd Woytek, (King of Prussia) joined a panel at the CLM Alliance (Claims and Litigation Management Alliance) Work Comp Conference in Nashville to present "We See You: How Employee Engagement Enhances Work Comp Outcomes." Judd and his fellow panelists discussed the positive impact of employee engagement on claim outcomes, return-to-work timelines, and overall claim costs.

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.
