Defense Verdict on Behalf of Hospital and Emergency Department Doctors

We obtained a defense verdict on behalf of one of the Philadelphia region’s largest hospitals and two of its Emergency Department physicians after a six-day jury trial in a complex and extremely emotional case involving the death of 7-year-old child. Allegations of negligence surrounded the failure to admit and perform a urine drug screen on an 18-year-old who presented high on synthetic marijuana or K2. We argued that the doctors appropriately performed numerous exams, tested and monitored the patient until he achieved clinical sobriety. The patient was discharged, then 22 hours later smoked more K2 and within two hours strangled his 7-year-old sister to death. 

Sex Trafficking and Abuse Claims Against Hotel Successfully Dismissed

We were successful in having all claims against our client’s hotel dismissed. This case involved deeply distressing allegations of sex trafficking and abuse by the plaintiff’s mother, occurring when the plaintiff was a minor. The claims against our client’s hotel were brought under the Trafficking Victims Protection Reauthorization Act (TVPRA) and Florida law. While the court was unequivocal in acknowledging the tragic and serious nature of the plaintiff’s allegations against her abusers, it ultimately found that the legal claims against our client were not supported by sufficient factual allegations to state a cause of action under either federal or state law. The court had previously dismissed the original complaint without prejudice. However, upon review of the amended complaint, the court agreed with our renewed motion to dismiss and concluded that the plaintiff failed to plausibly allege that our hotel knowingly participated in a trafficking venture or maintained a continuous business relationship with the traffickers. The amended complaint alleged only a single instance of trafficking at our client’s hotel and asserted that the conduct was so blatant that hotel staff should have recognized it. The court found this insufficient to support a claim under the TVPRA. Additionally, the court found that the allegations did not meet the high legal threshold required to sustain a claim for intentional infliction of emotional distress under Florida law.

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 Atty. 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 Attys. 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.

Vendor Cyber Attack Compromises PII of More Than 3 Million Hunting and Fishing License Holders in Texas

The Texas Parks & Wildlife Department (TPWD) announced earlier this month that one of its vendors which handles the sale of state hunting and fishing licenses was the victim of a cybersecurity attack. The threat actor appears to have exfiltrated personal driver’s license information, passport numbers, email addresses, phone numbers and addresses of over 3 million hunting and fishing license holders.  The State Parks Department advised that the attack did not compromise social security numbers, dates of birth or financial information. Texas Cyber Command, the state’s new cybersecurity authority formed to protect critical infrastructure and coordinate threat responses across state and local government, reportedly assisted in detecting and containing the attack. TPWD has already set up free credit monitoring for those impacted through Kroll.  According to press reports, no specific group has yet been identified as the perpetrator of the theft. TPWD also advised that business has not been interrupted and license sales were continuing. This incident once again demonstrates that cybersecurity is only as strong as the weakest link in the supply chain. Businesses must prioritize security across their own environments and those of their vendors and contractors as well.

Summary Judgment Secured, Preserving $750,000 in Coverage for Insured in Major Trucking Liability Dispute

Ray Freudiger and Michael A. Roberts (both of Cincinnati) successfully obtained summary judgment on behalf of their client in a coverage dispute arising from a May 19, 2022, motor vehicle accident. A permissive driver operated a box truck for an interstate trucking company and caused severe injuries to two tort victims. Prior to the accident, the insured had procured a commercial auto policy for the trucking company with stated limits of $1,000,000. Following the accident, the insurer initiated a declaratory judgment action asserting that only reduced bodily injury limits of $25,000/$50,000 applied and later counterclaimed, alleging it would not have insured the driver had he been properly submitted for approval under the policy. After extensive discovery, briefing, and oral argument, the court rejected the insurer’s attempt to shift responsibility for the $750,000 in coverage it was legally required to provide for permissive drivers under Ohio law, granting summary judgment in favor of the insured and preserving $750,000 in liability exposure.

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.
