Philadelphia Commerce Court Grants Summary Judgment, Dismissing $2M Unfair‑Competition and Tortious‑Interference Claims

We obtained summary judgment dismissal, following Oral Argument, in a Philadelphia Commerce Court commercial litigation matter involving allegations of unfair competition and tortious inference with contract and business relationships, brought by one adult day care center against our client, a competing adult day care facility.  The plaintiff’s suit stemmed from alleged violation of regulations set forth by the Pennsylvania Department of Aging and its Office of Long-Term Living. The plaintiff’s final demand was $2 million, and no settlement offers were made before the trial court granted summary judgment.

One Month – 4 Outstanding Results! Aaron Moore Obtained Four Successful Results on Behalf of Clients in the Span of One Month

Defense verdict on behalf of a real estate broker and agent. The plaintiffs, homebuyers, claimed that the sellers’ broker and agent were liable to them for the value of fixtures that were taken by the sellers when they vacated the property, which were alleged to have been included in the sale. At a bench trial, the judge determined that neither the broker nor the agent could be held liable to the plaintiffs because the representations regarding what was included in the sale were made by the sellers. Supreme Court affirmance of dismissal of a complex legal malpractice lawsuit. Aaron and Carol Vanderwoude obtained a Delaware Supreme Court affirmance of the trial court’s dismissal of a complex legal malpractice claim. The plaintiffs, seven affiliated companies and their owners in the business of developing property, had been sued by their bank for defaulting on multiple lines of credit. The bank filed multiple lawsuits against the property developers, claiming approximately $7 million in damages, plus attorneys’ fees, which were recoverable pursuant to the terms of the promissory notes. The property developers retained our client to defend the lawsuits, asserting that the amounts claimed to be owed to the bank were significantly overstated. Our client vigorously defended the bank’s underlying lawsuits. Ultimately, the property developers settled the bank’s lawsuits for the entire amount owed, plus interest and the bank’s legal fees. The developers argued that its attorneys should have advised them to settle the bank’s claims after the lawsuits were commenced and that, if they had done so, they would not have had to pay the bank’s legal fees, our client’s legal fees, or expert witness fees, or the additional interest on the loan. The property developers also claimed that not settling with the bank earlier caused them lost business opportunities valued at nearly $1 million. The plaintiffs’ legal malpractice claims were dismissed because their expert witness, a Maryland attorney with no business litigation experience, was not qualified to serve as an expert and because their damages claims were speculative. Motion to dismiss in complex matter involving claims of fraud, misappropriation of trade secrets, tortious interference with contractual relations, and piercing the corporate veil. The plaintiff, an investment fund, had purchased a business that was controlled and primarily owned by our client. The business ultimately went bankrupt, and the plaintiff claimed that the purchase was premised upon misrepresentation by our client. The plaintiff maintained that jurisdiction in Delaware was proper pursuant to the Asset Purchase Agreement. The District Court was persuaded by arguments reflecting that it lacked personal jurisdiction over our client, a citizen of Canada, even though he signed the Asset Purchase Agreement which included language conferring jurisdiction over claims arising from the sale in Delaware. The court agreed that our client did not sign the agreement in his individual capacity, and the plaintiff’s piercing the corporate veil allegations were insufficient to confer personal jurisdiction. Dismissal of an unjust enrichment claim. Obtained dismissal of an unjust enrichment claim brought by a condominium unit owner against the attorneys who represented her condominium association. The unit owner claimed that the law firm was liable to her for unjust enrichment in connection with legal fees it received from the association for legal services provided in efforts to collect on past due assessments owed by the unit owner. Pursuant to the association’s governing documents, the charges were passed on to the unit owner. The court agreed that the fees that were paid to our client by the condominium association were properly earned.

Cross-Border Discovery: Why Local Counsel Is Indispensable

October 17, 2025

When engaging in cross-border discovery, one must be mindful of the differences in jurisdictional issues, including but not limited to, blocking statutes, data privacy, and attorney-client privilege differences. While it is essential to have a working knowledge of discovery rules in the jurisdiction you’re seeking information in, it is also essential to engage local counsel from the outset, to help navigate jurisdictional specific issues.

New York Court Reaffirms Internal Affairs Doctrine, Denies Standing in Derivative Suit Against English Corporation

July 1, 2025

“Few principles are more firmly entrenched in corporate law than the internal affairs doctrine, a choice-of-law rule providing that, with rare exception, the substantive law of the place of incorporation governs disputes relating to the rights and relationships of corporate shareholders and managers.” Thus opened the court’s opinion—but that did not stop the challenge mounted against it in this case. Ezrasons, the plaintiff, is a New York corporation that is the beneficial owner of shares in Barclays PLC, a bank holding company incorporated under the laws of England and Wales with its principal office in London. Ezrasons filed suit “on behalf of Barclays” against directors and an affiliated company, alleging various breaches of fiduciary duty. Those defendants moved to dismiss for lack of standing because Ezrasons is not “a registered member of Barclays,” a substantive limitation on the right to maintain derivative actions under English law. With seemingly no dispute as to the requirements of English law, Ezrasons argued, instead, that New York’s Business Corporation Law gave it the right to maintain its action in New York. On appeal, the question was whether the New York statute (BCL) displaced the internal affairs doctrine in New York common law. The answer—spread over 24 pages, and over the 57-page dissent of two dissenting Justices who accuse the majority of working to impress Marty McFly and Doc Brown with their ability to travel back in time—was no. But while the genesis of the doctrine is the nineteenth century’s corporate boom and expansion of interstate corporate operations, the rationale for upholding the rule is decidedly timeless. Like the U.S. Supreme Court, the Court of Appeals reaffirmed its stance that “only one state should have the authority to regulate a corporation’s internal affairs,” lest a company “be faced with conflicting demands.” Thus, the court held that the Business Corporation Law, which allows suits to be brought in the name of domestic or foreign corporations, does not unequivocally displace the substantive applicability of English law as regards suits in the name of English corporations. Instead, the BCL establishes the minimum predicate for New York courts to entertain the suit, without bestowing standing contrary to the law of the foreign corporation’s home. Thus, companies with operations in the Empire State can rest assured that their internal operations and “disputes relating to the rights and relationships of corporate shareholders and managers” will remain governed by the substantive law of their state of incorporation.    Case Law Alerts, 3rd Quarter, July 2025 is prepared by Marshall Dennehey to provide information on recent developments of interest to our readers.

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 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.
