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.

Commonwealth Court Holds That a Claimant Who Was Struck By a Car While Crossing the Street During an Unpaid Break Was In the Course and Scope of Employment

This case involved a claim petition filed by a claimant who sustained injuries after being struck by a vehicle while crossing the street in front of the employer’s premises. The employer denied the claim based on course and scope, as the accident occurred during one of two mandatory fifteen (15) minute breaks provided to the claimant. The claimant would punch out at the beginning of a break and punch back in when the break was over.  On the date of the incident, the claimant punched out and left the building to get lunch at a restaurant, which required her to cross the employer’s parking lot, and then a public street, where the injury occurred. The Workers Compensation Judge (WCJ) dismissed the petition, noting that that during the two mandatory fifteen-minute breaks per shift allowed by the employer, the claimant was free to leave the employer’s premises, and during breaks, permitted to engage in whatever activity she desired. The WCJ found that at the time of the accident, the claimant was on her own time, in the middle of the street, and going to get lunch.   The claimant filed an appeal with the Worker’s Compensation Appeal Board (Board), and the Board reversed.  According to the Board, the claimant’s location was still on the employer’s premises, as the claimant was taking her customary route while using a reasonable ingress/egress from the employer.  Further, the Board found that the “Personal Comfort Doctrine” applied, as the claimant was on a momentary departure to take care of her personal comfort, within the window of time she was allotted for her break.  The Board remanded the case, and a WCJ granted the claim petition.  The Board affirmed, and the employer appealed to the Commonwealth Court. Before the Court, the employer argued that the claimant was not in the course and scope of her employment, because the injury did not occur on its premises, and the claimant was outside the bounds of the Personal Comfort Doctrine. The Court, however, rejected these arguments, and dismissed the employer’s appeal.  The Court noted that the break given to the claimant was so cursory, when she set out to relieve her hunger for her own personal comfort,  she remained in the course of her employment when she sustained her injuries.  A Petition for Allowance of Appeal in the Supreme Court has been filed by the Employer, Giant Eagle.

Appellate Court Rejects Horizontal Immunity Defense to Company Not Acting as Statutory Subcontractor

The First District Court of Appeal held that a property management company was not entitled to horizontal immunity under section 440.10(1)(e), Florida Statutes, in a negligence action brought by an employee of another company working on the property. The claimant was injured while servicing a swimming pool at an apartment complex. His employer had contracted with the property owner to maintain the pool. Following the accident, the claimant received workers' compensation benefits through his employer’s carrier. The claimant subsequently filed a negligence action against the property management company, alleging that it failed to maintain the premises in a reasonably safe condition and failed to warn him of a dangerous condition that caused his injuries. The property management company had been retained by the property owner to maintain the complex in good operating condition and to perform routine maintenance and repair work. The property management company argued that it was immune from suit under section 440.10(1)(e) of Florida’s Workers’ Compensation Law. That provision grants immunity to a subcontractor providing services in conjunction with a contractor on the same project or contract work from civil actions brought by employees of another subcontractor, subject to limited exceptions. According to the property management company, it qualified as a subcontractor working on the same project as the claimant’s employer and was therefore entitled to horizontal immunity. The trial court agreed and entered summary judgment in its favor. On appeal, however, the claimant argued, and the appellate court agreed, that horizontal immunity applies only when a contractor has sublet work arising from a contractual obligation owed to a third party. The court noted that prior decisions consistently held that an entity acting solely on its own behalf as the owner of property, rather than pursuant to a contract with a third party, is not a “contractor” under section 440.10(1), even when it hires other companies to perform work on the property. In Teed, the property management company could not establish that the property owner had a primary contractual obligation to a third party to maintain either the apartment complex or the swimming pool, which it then delegated to the claimant’s employer or the property management company. As a result, the property owner did not qualify as a statutory contractor, and the property management company was not a subcontractor entitled to horizontal immunity under section 440.10(1)(e). The First District therefore reversed the lower court’s ruling and remanded the case for further proceedings on the claimant’s negligence claim.
