    • Successfully defended an appeal from a jury verdict previously secured by Aaron Moore and Alesia Sulock (Philadelphia) in favor of the firm’s client in a legal malpractice case. The plaintiffs initially asserted multiple tort claims and a claim under the Unfair Trade Practices and Consumer Protection Law, which were dismissed by the trial court upon partial grant of the defense’s motion for judgment on the pleadings. The case proceeded to trial on a remaining breach of contract claim, resulting in a defense verdict. On appeal, the plaintiffs challenged the trial court’s rulings on both the motion for judgment on the pleadings and a motion in limine related to evidentiary exclusions. The Pennsylvania Superior Court unanimously affirmed the trial court’s rulings, holding that the tort claims were time-barred and that the plaintiffs had waived their evidentiary argument by failing to properly develop it in their appellate brief.
    • Successfully defended a national homebuilding company in a Philadelphia arbitration involving a motor vehicle negligence claim. The plaintiff falsely alleged he was a passenger in a vehicle operated by an independent contractor, triggering a contractual indemnity dispute. The arbitration panel found no liability and concluded the plaintiff’s claims were fraudulent. The panel also ordered the co-defendant to reimburse all reasonable attorneys’ fees expended in the defense pursuant to the indemnity agreement.
    • Obtained Defense Verdict in Slip and Fall Arbitration Matter: Plaintiff alleged that she slipped and fell on a wet floor in a check cashing facility in Philadelphia. On cross examination, Plaintiff admitted that she saw the wet floor prior to walking through it twice, slipping and falling on her second trek through the wet floor. She also admitted on cross-examination that she had prior similar injuries. During closing arguments, we argued that the wet floor was open and obvious, Plaintiff assumed the risk by walking through it, and that she required expert testimony to support her causation arguments. We further argued that Plaintiff failed to meet her burden of proof regarding our client’s responsibility for maintaining the property. The Arbitration panel agreed with our arguments and entered a defense verdict on behalf of our client. 
    • Obtained Defense Verdict in Slip and Fall Arbitration Matter: Plaintiff alleged that she slipped and fell on a wet floor in her workplace, and brought suit against our clients, the owner and property manager of the building. On the day of the arbitration, Plaintiff introduced, for the first time, a $70,000 wage loss lien in support of her claims. We successfully argued that the lien and Plaintiff’s wage loss claim should be precluded at the arbitration due to her failure to produce the documents in a timely manner. Regarding liability, Plaintiff subpoenaed her employer to testify about who was responsible for maintaining the inside of the premises. On cross-examination, the employer admitted it was their duty to maintain the premises and that our clients were not responsible for the wet floor. The Arbitration panel entered a defense verdict for our clients.
    • Obtained Defense Verdict in Trip and Fall Arbitration Matter: Plaintiff alleged that she tripped and fell on broken sidewalk in Philadelphia, and brought suit against our client, the owner of the property. On cross-examination, I introduced evidence that Plaintiff fainted rather than tripped and fell, and argued that she required expert testimony to support her damages claims. Plaintiff denied that she fainted and introduced photographs of the broken sidewalk. The Arbitration panel entered a defense verdict in favor of our clients, finding that Plaintiff did not trip and fall on the broken sidewalk.
    • Obtained Defense Verdict in Rear-End Collision Case: Plaintiff was rear-ended by our client, a bus driver. Through Requests for Admission, we successfully obtained evidence supporting a limited tort defense. At arbitration, we argued that Plaintiff failed to exhaust his PIP benefits policy and, therefore, was precluded from entering any medical bills into evidence. Plaintiff attempted to argue at the arbitration that his injuries breached the “serious injury” threshold, and that he was entitled to non-economic damages. The Arbitration panel found in our favor, ruling that while our client caused the accident, Plaintiff’s injuries did not meet the “serious injury” threshold and, therefore, entitled to no damages as a matter of law.  
    • Successfully Asserted Limited Tort Defense at Arbitration in Rear-End Collision Case: Plaintiff alleged that she suffered injury due to a motor vehicle accident caused by our client. For purposes of the Arbitration, we admitted that our driver caused the accident, but that Plaintiff was limited tort and did not breach the serious injury threshold. Plaintiff attempted to argue that she breached the serious injury threshold because her injuries caused her severe hardship with taking care of her two children, each of whom had learning disabilities. On cross-examination, we introduced evidence that Plaintiff had similar pre-existing injuries, which Plaintiff denied. Because of the pre-existing injuries, we argued that Plaintiff required expert testimony to support her causation arguments. The Arbitration panel found that Plaintiff did not breach the serious injury threshold and, therefore, she was entitled only to her economic damages, which were approximately one-third of Plaintiff’s lowest pre-arbitration demand.

Defense Verdict Obtained in Philadelphia Arbitration Matter

We were successful in a Philadelphia arbitration matter, obtaining a defense verdict as to the plaintiff’s claims and an order requiring the co-defendant to reimburse attorneys’ fees. It was undisputed that a motor vehicle accident occurred involving a third-party independent contractor of our client, a prominent homebuilding company. The plaintiff claimed he was a passenger in the vehicle and, accordingly, brought a negligence action against our client, who tendered its defense to the independent contractor based on a contractual provision requiring defense and indemnification. The independent contractor denied the tender. During discovery, it was revealed that the plaintiff falsely claimed he was a passenger in the vehicle. The independent contractor again denied the tender, claiming that its duty to defend was never triggered. The case proceeded to an arbitration where the panel found neither defendant was liable but disagreed with the co-defendant’s arguments regarding defense and indemnity. Accordingly, the arbitration panel entered a judgment in favor of our client and ordered the co-defendant to reimburse all reasonable attorneys’ fees expended defending the action.

Multimillion Dollar Default Judgment Successfully Struck Down by Appellate Court

We succeeded in striking a $4.1 million default judgment entered in the Philadelphia Court of Common Pleas by a plaintiff who alleged defective residential construction. We convinced the court that Pennsylvania Prothonotaries and Clerks of Court lack authority to accept a praecipe to enter a default judgment in a specified amount unless the amount is approved by a judge or is a sum certain, meaning that the amount is ascertainable from a confessed judgment or a contract that specifies the amount due. The default judgment had spawned significant coverage litigation by and against the defendant’s insurer.

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.

Court Dismisses Claims in Electrocution Death, Citing Shotgun Pleading and Immunity for Decedent’s Employer

July 1, 2025

Carlos Melendez was working on a “transmission tower painting crew” for one of several named defendants when he was electrocuted and killed while working in the course and scope of his employment. After his death, Mr. Melendez’s parents settled a workers’ compensation claim against his employer, Morris Painting, and subsequently brought suit against Morris, several electrical utility entities linked to the transmission tower painting project, and three of those entities’ employer who allegedly were involved in the project.  After the plaintiffs’ original complaint was dismissed as an improper “shotgun pleading,” they filed an amended complaint, lumping together the utility corporations, making allegations that: they “or any one of them ... owned the electricity that killed ... Melendez”; they “or any one of them ... had substantial control over the electricity that killed ... Melendez”; they “or any one of them ... owned the transmission tower and/or the associated equipment that ... Melendez came in contact with when he was killed”; they “or any one of them ... had a possessory interest in the transmission tower and/or the associated equipment that ... Melendez came in contact with when he was killed.” The amended complaint contained several other allegations similar to the ones above with no specificity directed toward the individual defendants, including some general averments against Morris, as well.  The court granted several motions to dismiss, paring down the complaint significantly. In particular, the court dismissed all claims against the decedent’s employer, with prejudice, because it determined that any amendments to the complaint by the plaintiffs would be futile. As for the so-called “utility defendants” improperly lumped together, the court dismissed all claims without prejudice, providing the plaintiffs another opportunity to amend the complaint with more specific allegations of negligence. Plaintiffs will often plead complaints in a similar fashion, lumping several defendants together and lobbing general averments of negligence against all of the defendants. This case highlights that defendants must move aggressively to strike improperly pled cases, especially in federal court, where dispositive motions are more likely to be granted.    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.

Ohio Supreme Court Holds That a Binding Appraisal Award May Not Be Set Aside Absent Specific Evidence of Manifest Mistake or Fraud

On July 23, 2026, the Ohio Supreme Court issued a rare opinion on the binding effect of an appraisal award in a property insurance policy.  The Court in One Church held: A binding appraisal award will not be set aside unless an error is so palpably wrong that it undermines the intent of the agreement, such as corruption or gross mistake, not a mere error of judgment—To plead a claim of mistake with particularity as required by Civ.R. 9(B), facts alleged in a complaint must constitute the elements of mistake—Allegation that additional, hidden damage was discovered after appraisal award failed to state a claim of mistake that could justify setting aside binding appraisal.  The case arose out of a claim brought by One Church against its insurer, Brotherhood Mutual Insurance Company for roof damage from a storm. Pursuant to the terms of the insurance policy, the parties agreed to submit the matter to appraisal. The two appraisers inspected the building, and both appraisers agreed that the damages were $313,271.98. The insurer paid the agreed appraised amount.  Thereafter, the insured submitted a claim for an additional $206,663.09 in damages. The insured argued that these additional damages were not discovered until after the repairs began, and that they should be permitted to submit an additional claim, even though there had already been a binding appraisal of damages. The insurer refused to pay the additional damages, and the insured sued for breach of contract and bad faith.  In the trial court, the insurer moved to dismiss for failure to state a claim, arguing that the binding appraisal award barred any further claims. The insured took the position that additional hidden damages could not be discovered until after the repairs began, and therefore there was a mutual mistake. The trial court dismissed the case on the insurer’s motion, because there was no “evidence of fraud, misfeasance, or mistake”. The Court of Appeals agreed that appraisal awards are generally binding, but noted that an appraisal award can be set aside for fraud or manifest mistake. The Court of Appeals reversed and remanded the case to the trial court, finding that the insured had pled mistake with sufficient particularity. The insurer appealed to the Ohio Supreme Court. On appeal, the Ohio Supreme Court reversed the Court of Appeals, and reinstated the trial court decision dismissing the case for failure to state a claim upon which relief can be granted. The Supreme Court found that since the insured had already demanded appraisal, and the appraisal award was binding, “something more than error of judgement, such as corruption in the arbitrator, or gross mistake” must be pled with particularity, and proven for the insured to override the appraisal award. Since the complaint did not allege fraud or manifest mistake with sufficient particularity, something more than a mere error of judgment, the complaint was insufficient to state a claim.  The complaint in this case did not challenge the appraisal award. It pled that additional damages were discovered that were not apparent when the appraisal was done. It did not specify “who discovered the damages, how they were discovered, where they were found, why they were previously hidden, or why they rise to the level of a manifest mistake that the “appraiser would have corrected...had it been called to his attention”. Id at ¶22 citing Lakewood Mfg. Co. v. Home Ins. Co. of New York, 422 F.2d 796, 798 (6th Cir. 1970). Cases deciding the effect of appraisal awards are unusual. The Ohio Supreme Court’s decision in One Church relies primarily on 19th century case law for its conclusion. This emphasizes the fact that there is minimal case law deciding the effect of binding appraisal clauses in property insurance policies, and makes this case all the more significant. A lengthy dissent was written by Justice Fisher, who would have affirmed the Court of Appeals decision reversing and remanding the case for a decision on the merits. Of course, the decision works both ways, and an insurer dissatisfied with a binding appraisal award will likewise be without further recourse absent evidence of corruption, fraud, misfeasance, or manifest mistake, which must be pled with particularity. To constitute manifest mistake, “the mistake must be of such character that the arbitrator or appraiser would have corrected it had it been called to his attention.”  Lakewood Mfg. Co. v. Home Ins. Co. of New York, 422 F.2d 796, 798 (6th Cir. 1970).  The majority opinion does not specifically identify what would have been sufficient to plead mistake with particularity, or if the insured could have amended the complaint to overcome the deficiencies. The dissent argues that this was not really a case alleging mistake, but rather a question of contract interpretation. The insured did not challenge the appraisal, but argued that the hidden damage was not part of the appraisal, and the appraisal only covered the known damages.  However, this argument did not carry the day with the majority.  *Thomas F. Glassman, a shareholder in Marshall Dennehey’s Cincinnati office, filed a brief in the Ohio Supreme Court on behalf of the Ohio Association of Civil Trial Attorneys, in support of the insurer’s position.
