  • Assisted in securing a unanimous 6-0 defense verdict in a New Jersey premises liability case after the jury found no negligence on the part of the defendant. The plaintiff alleged that a six-foot drill bit fell from a retail display, causing a concussion, post-concussion syndrome and permanent cognitive impairments. The defense demonstrated that the item was displaced only after an unidentified customer struck the shelving with a shopping cart and that there was no evidence store employees knew or should have known of the condition. Through surveillance video, fact witness testimony and expert evidence, the defense also established that the impact was inconsistent with the forces necessary to cause a concussion and highlighted alternative explanations for the plaintiff's claimed injuries. Following a six-day trial, the jury returned a complete defense verdict, finding the defendant was not negligent.

    Secured a unanimous defense verdict in a premises liability matter involving a national home improvement retailer. The plaintiff alleged that she developed Complex Regional Pain Syndrome (CRPS) following a fall in the retailer's parking lot in October 2022. Plaintiff claimed that the incident necessitated significant ongoing medical treatment, including the implantation of a permanent spinal cord stimulator. The plaintiff sought substantial damages, including claims for extensive future medical care. The defense team successfully challenged the credibility of the plaintiff's allegations and expert testimony through rigorous cross-examination and the presentation of defense experts in forensic engineering, human factors, and pain management. The defense also demonstrated that the plaintiff's alleged condition was attributable to pre-existing medical issues rather than the incident at issue. Following a six-day trial, the jury deliberated for just 42 minutes before returning a unanimous verdict finding no negligence on the part of the defendant.

    Secured a no-cause verdict on behalf of a national home improvement retailer in a personal injury action. The plaintiff alleged that on May 20, 2019, she was injured at one of the retailer’s stores when an associate moved a lumber cart, causing a PVC pipe to fall and strike her head and right shoulder. She claimed permanent traumatic brain injury, concussion, and spinal injuries, supported by her orthopedic and neurologic experts. Our defense orthopedic and neurologic experts testified that the plaintiff’s reported symptoms were more consistent with malingering or a somatoform disorder. After a one-week trial and approximately 45 minutes of deliberation, the jury unanimously found the defendant was not negligent. The last demand was $1.2 million, and the final offer was $100,000.

    Obtained summary judgment in favor of an automobile liability insurance carrier, wherein court upheld carrier's disclaimer of defense and indemnity coverage to its insured in response to personal injury lawsuit brought against insured arising from motor vehicle accident on the basis that insured had made material misrepresentations on his insurance policy application as to where he resided and principally garaged the insured vehicle.

    Successfully represented an insurance carrier in a declaratory judgment action, wherein carrier disclaimed coverage to insured under an automobile liability insurance policy with regard to an underlying personal injury lawsuit brought against insured arising from a motor vehicle accident because insured failed to provide the carrier with notice of either the accident or the resultant lawsuit and which, in turn, substantially prejudiced the insurer.

    Obtained summary judgment on behalf of defendant employers and having all claims against them dismissed in civil lawsuits brought against them by their own employees for injuries the employees sustained in the workplace on the basis that there was no evidence to support a finding that the "intentional wrong" exception to the workers' compensation bar applied. In one of these cases, in particular, after successfully in having the plaintiff employee's claim against his employer dismissed, the employee continued to litigate his claim against the remaining defendant, a forklift manufacturer, resulting in a jury verdict in favor of the plaintiff in excess of $1 million, which was subsequently affirmed on appeal.

    Obtained summary judgment in favor of a commercial general liability carrier in a declaratory judgment action, successfully limiting the CGL carrier's potential liability exposure in a case involving serious injuries to two plaintiffs as a result of a robbery. Received a favorable ruling from the court that the $100,000 aggregate policy limit, set forth in the CGL policy's Assault & Battery Endorsement, was the applicable liability coverage limit potentially available to the injured plaintiffs under the CGL policy and not the $1 million per occurrence coverage limit, set forth in the policy's Declarations, as was argued by the plaintiffs.

    Successfully defended a CGL insurance carrier in a claim brought against it by the landlord/owner of a warehouse for defense and indemnity coverage as an Additional Insured under a CGL insurance policy issued by the carrier to one of the tenants at the warehouse in a high-exposure property damage loss case arising from a fire on the basis that the landlord did not qualify as an additional insured on the policy pursuant to the Additional Insured Endorsement and the landlord's claim should be a claim against its insurance broker for professional negligence in not procuring the proper insurance coverage requested by the landlord.

    Obtained summary judgment in favor of a subcontractor on an indemnity cross-claim, where the contract at issue, between the subcontractor and the general contractor, did not include the required express language that the general contractor would be indemnified for own negligence.

Summary Judgment for Insurer in Complex Coverage Case

We successfully persuaded the court to grant summary judgement on behalf of a major insurer on a complex coverage issue. This coverage case concerned two Virginia personal automobile policies in regard to an automobile accident in New Jersey. The son of a divorced couple sought coverage for an accident he was involved in on a major thoroughfare in New Jersey. At the time of the accident, the son was operating a motor vehicle owned by another Virginia resident, and he had the reasonable expectation that he had permission to operate the vehicle. The accident was very serious, and he sought coverage under both of his parents’ policies. As to the mother’s policy, we convinced the court that the son was not an insured under her policy because he was not so designated on the policy’s declaration page, which was a specific condition of the policy pursuant to Virginia law. As to the father’s policy, once again, we convinced the court that the son was not an insured under this policy given the fact that the mother had sole and exclusive custody under the divorce agreement; thus, the son was not a resident relative of the father’s household. Therefore, neither policy provided coverage for the son, and the insurer was totally dismissed from the case.

Court Agrees Mode of Operations Does Not Apply in Retail Liability Case

We were successful on a motion for summary judgment, thereby barring the application of the mode of operations in a slip and fall case where an alleged partially eaten sandwich was found in the aisle of the retailer. ​The facts indicated that the sandwich came from a fast-food sandwich shop within the premises and was dropped by an unidentified customer, who took the item to go and dropped it in the aisle before the plaintiff fell. The court ruled that the mode of operations did not apply because the aisle, which contained greeting cards and the like, and did not create an extension of the cafeteria within the retailer’s premises. Further, the court ruled there was no nexus to any self-serve component of the fast food restaurant’s business to the area in the retailer’s store proper where the accident occurred.

Pennsylvania Superior Court Reaffirms Liberal Pleading Standard in Medical Malpractice Actions

Legal Roundup: Pennsylvania The Pennsylvania Superior Court has reinforced a broader fact-pleading approach that may make it more difficult for health care defendants to obtain dismissal at the preliminary objection stage. In DaSilva v. Abington Memorial Hospital, the court held that the plaintiffs’ second amended complaint satisfied Pennsylvania’s fact‑pleading requirements despite the absence of individually named negligent actors. In DaSilva, the plaintiffs filed a second amended complaint alleging that Abington Memorial Hospital was directly and vicariously negligent after the patient, who was experiencing a mental health crisis, was left unattended by hospital staff, exited the emergency department, and was struck by a vehicle, suffering serious injuries. The trial court sustained the hospital’s preliminary objections and dismissed the complaint with prejudice, stating plaintiffs “failed to plead any material factual allegations in support of their claims of negligence [and] set forth vague allegations of negligence and unidentified agency.” Id. at *5. The plaintiffs appealed. On appeal, the Superior Court reversed, holding that the complaint sufficiently pled negligence and vicarious liability claims under Pa.R.C.P. 1019(a). The court concluded that allegations describing the patient’s condition, the hospital’s awareness of that condition, and the alleged failure to monitor or prevent elopement were adequate to satisfy Pennsylvania’s pleading requirements. Significantly, the court rejected the hospital’s argument that the complaint failed because it did not identify the specific employees responsible for the alleged negligence. Instead, the court found that generalized references to “emergency room staff” were sufficient to place the hospital on notice of the claims because “the names of those who performed services for the plaintiff are known to the defendant or can be ascertained during discovery.” Id. at *12 (citing Est. of Denmark ex rel. Hurst v. Williams, 117 A.3d 300, 307 (Pa. Super. 2015)). The effect of DaSilva is that plaintiffs may proceed past the pleading stage with relatively generalized allegations, particularly in cases involving institutional defendants where relevant details are uniquely within the defendant’s control. As a result, health care defendants should anticipate that challenges to claim sufficiency may be resolved in the later stages of litigation, including discovery and summary judgment.

The Ohio Supreme Court Extends Sham-Affidavit Rule to Contradictory Expert Reports

Legal Roundup: Ohio In its June 23, 2026, decision in Moore v. Mercy Medical Center, the Ohio Supreme Court upheld a trial court’s decision to strike an expert witness’s affidavit that contradicted the opinions expressed in the expert’s prior report. This case pertains to allegations of medical malpractice after plaintiff Cheri Moore gave birth to an infant in respiratory distress who required intubation. Moore alleged that a delay in ordering an emergency cesarean section resulted in the need for intubation, causing her child’s injuries. Specifically, Moore sued Dr. Meniru, who completed his first shift at 7:00 a.m. on May 28, 2015, and did not resume treating Moore until 7:00 a.m. on May 29, 2015. One of Moore’s expert witnesses authored a report stating that the doctors, including Dr. Meniru, deviated from the standard of care by not advocating for a cesarean section in the evening of May 28, 2015. Based on this report, Dr. Meniru moved for summary judgment, arguing that the alleged breach occurred during a period when he was not on duty. In response to the summary judgment motion, the plaintiff filed an affidavit from the same expert. Although the expert expressly incorporated his previous report into his affidavit, he also offered an additional opinion: that Dr. Meniru breached the standard of care by failing to begin a cesarean section within 30 minutes of receiving reports of fetal distress. Dr. Meniru filed a motion to strike the expert’s affidavit, arguing that it contradicted the opinions set forth in his prior report in violation of the sham-affidavit rule. The sham-affidavit rule applies to “a contradictory affidavit that indicates only that the affiant cannot maintain a consistent story, or is willing to offer a statement solely for the purpose of defeating summary judgment”. Moore, supra, at ¶ 19, citing Pettiford v. Aggarwal, 126 Ohio St.3d 413, 2010-Ohio-3237. The trial court granted both the motion to strike and the motion for summary judgment, and the Fifth District affirmed. The Ohio Supreme Court accepted two questions of law: (1) whether the sham-affidavit rule applies when the sworn testimony contradicts prior unsworn statements; and (2) whether an inconsistency within the affidavit goes to credibility or admissibility, justifying an order striking the affidavit. Previous rulings by the Ohio Supreme Court regarding the sham-affidavit rule have pertained to contradictions between an affidavit and sworn deposition testimony. See, e.g., Byrd v. Smith, 2006- Ohio-3455, 110 Ohio St.3d 24, 850 N.E.2d 47. However, here, the Court was asked to apply the same rule to contradictions between a sworn affidavit and an unsworn expert report. The Court held that, because Moore’s expert incorporated his prior report into his affidavit, he effectively adopted the report as part of his sworn testimony.
