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

Johnson v. Christiana Sch. Dist. 2026 Del. Super. LEXIS 324(302068301.1)

August 13, 2026

by Linda L. Wilson

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.

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.

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.
