    Delaware Superior Court Affirms Denial of Workers' Compensation for Teacher's Spinal Stroke: Work Stress Alone Insufficient Under "Substantial Cause" Standard

    August 13, 2026

    Angelina Johnson, a third-grade teacher, filed a workers' compensation petition seeking benefits for a spinal stroke she suffered on January 6, 2022, while at school preparing for a scheduled performance evaluation. The Industrial Accident Board denied her claim, finding that her work-related stress was not a substantial cause of the stroke. Johnson appealed to the Delaware Superior Court,  On January 6, 2022, Johnson was at school making copies in preparation for a scheduled annual performance evaluation when she suffered a spinal stroke. Johnson had multiple poorly controlled pre-existing medical conditions, including hypertension with readings reaching 187/95 and 170/100, and diabetes with A1C levels between 9.8 and 11.9.  Medical records dating to 2013 documented chronic uncontrolled hypertension and diabetes. Johnson was frequently non-compliant with her blood pressure medication, including during the three weeks before her stroke. With regard to her performance, Johnson had never received an "ineffective" rating and was not on probation or any performance improvement plan. The scheduled evaluation was a routine annual employment activity required of all teachers. The central issue on appeal was whether the Industrial Accident Board correctly applied Delaware's workers' compensation causation standards. Specifically, the court addressed two questions: (1) whether the Board properly applied the "substantial cause" standard from Duvall v. Charles Connell Roofing rather than the "but for" standard from Reese v. Home Budget Center, and (2) whether substantial evidence supported the Board's determination that Johnson's work stress was not a substantial cause of her spinal stroke.   The Superior Court affirmed the Industrial Accident Board's decision, holding that the "substantial cause" standard applied because Johnson's scheduled annual teacher evaluation, though stressful, was not an identifiable industrial accident—it was a routine employment activity, not a physical or unexpected event. The court further held that substantial evidence supported the Board's acceptance of the employer's medical expert testimony over Johnson's expert because the employer's expert reviewed a more complete medical history and relied on literature specific to spinal strokes.   The Superior Court held that the Board correctly applied the Duvall "substantial cause" standard rather than the Reese "but for" standard. The court reasoned that Johnson's scheduled annual performance evaluation was a routine employment activity, not an unexpected physical accident. The court next addressed whether substantial evidence supported the Board's finding that Johnson's work stress was not a substantial cause of her stroke.  The court found substantial evidence supporting the Board's decision to accept Dr. Townsend's testimony over Dr. Dogali's.  Dr. Townsend reviewed Johnson's medical records dating back to 2013, which documented a decade-long history of chronic uncontrolled hypertension and diabetes.  He relied on medical literature specific to spinal strokes. In contrast, Dr. Dogali reviewed only post-2022 medical records, relied on studies concerning cerebral strokes rather than spinal strokes, and incorrectly assumed that Johnson's medical conditions were recent developments.

    Delaware Court Bars Negligent Procurement and Contract Claims as Time‑Barred Under Three‑Year Limitations Period

    July 21, 2026

    In the matter of First State Cran Serv. V. L& W Ins., LLC, the Delaware Superior Court applied the three-year statute of limitations to bar claims for negligent procurement and breach of contract against an insurance broker. In this case, the plaintiff claimed that the broker negligently procured an insurance policy that included a policy exclusion which allegedly rendered the policy “worthless for the purpose for which it was intended.” The plaintiff argued that it was unfair to apply the three-year statute of limitations from the date of delivery of the policy, rather than from the date of coverage denial, and that its principal, as a lay person, could not have understood the policy exclusion, including because it was allegedly ambiguous. Applying the rule from Kaufman v. C.L. McCabe & Sons, Inc., the court held that, despite the seeming unfairness of the act-based rather than harm-based rule, that the Supreme Court has clearly required that the statute of limitations on a negligent procurement claim begins to run from the date of delivery of the policy. Addressing plaintiff’s arguments, the court found that the policy exclusion was not shown to be ambiguous, however, even if it was ambiguous, such an ambiguity does not make the coverage denial inherently unknowable.  Under one of two interpretations, the exclusion would apply and, thus, was knowable. The court relied on Kaufman in making this holding and applied the same reasoning to the breach of contract claim and dismissed both.  First State Crane Serv. v. L&W Ins., LLC, 2026 Del. Super. LEXIS 262 (June 16, 2026). This decision follows the rule set forth in Kaufman that the statute of limitations in a negligent procurement action against an insurance broker begins to run from the time of delivery of the policy. While the court recognized that other courts have taken a harm-based approach to the statute of limitations issue, this case highlights the act-based approach that the Delaware Supreme Court applies. Although the court was not unsympathetic to the plaintiff’s arguments that the statute of limitations would be unfair, this case also demonstrates that an insured is charged with notice of the policy and its exclusions upon delivery, even when a term of the policy is ambiguous and that a later denial of coverage is not relevant to an assessment of the statute of limitations. Despite plaintiff’s arguments that the exclusion was ambiguous, the court recognized that ambiguity would not relieve the plaintiff from being charged with such knowledge as of the date of delivery because “inherently unknowable” is a higher standard than mere ambiguity. In other words, if a term is subject to two interpretations, one that would include coverage and one that would exclude coverage, the risk of an exclusion of coverage was not “inherently unknowable.”  The court also distinguished this from cases where an affirmative misrepresentation or falsehood was present, such as a deed indicating an easement that never existed, because the falsity then was “inherently unknowable.” This case presents a strong defense for an insurance broker against negligent procurement (and breach of contract) claims where the claim is brought more than three years after the policy was delivered, even when ambiguity is alleged.  First State Crane Serv. v. L&W Ins., LLC, 2026 Del. Super. LEXIS 262 (June 16, 2026).

    Defense Jury Verdict Obtained Before the Delaware Superior Court

    We received a defense jury verdict before the Delaware Superior Court, New Castle County. Although liability was undisputed at trial, damages were disputed. The plaintiff sought damages for head, neck, back and left shoulder injuries. He had $350,000 in future medical bills and $78,000 in past medical bills that he could board. The plaintiff also had a $5 million lost wage claim that we were able to get dismissed prior to trial on a motion in limine.

    Petition to Terminate Ongoing Receipt of TPD Benefits Granted on Basis that Claimant Voluntarily Removed Himself from the Workforce

    The Industrial Accident Board (IAB) granted our petition to terminate the ongoing receipt of temporary partial disability (TPD) benefits on the basis that the claimant had voluntarily removed himself from the workforce. The claimant was a correction officer who suffered head injuries in an altercation with an inmate. He was out of work for a time and eventually released to return to work on modified duty. His restrictions were permanent and, because they could not be accommodated by his employer, he was placed on TPD. After more than a year with no indication of an attempt to return to the workforce, we challenged his ongoing entitlement to receive TPD. We worked with the employer to obtain documentation regarding the claimant’s job search (or lack thereof), other sources of income (pension, Social Security) and recreational/social activities since he had been separated from employment. In addition, we put forward both medical and vocational expert testimony at the hearing. As a result, the IAB reasoned that the claimant was able to work in a medium-duty job, that jobs were available within his restrictions, the he had conducted a minimal job search since his work release more than a year and a half earlier, and that his description of his daily activities was consistent with a person content with a retirement lifestyle rather than someone who intended to continue to work. Accordingly, he was no longer entitled to wage replacement benefits.

    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.

    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.

    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.
