Third Circuit Holds There Is No Right to Intervention in a Medical Context

March 1, 2024

Key Points:  There is a constitutional right to medical care for those individuals in custody.  Although there is a right to have a government actor intervene when the underlying constitutional violation involves excessive force or sexual assault of a person in custody or detention, the Third Circuit, in Thomas v. City of Harrisburg, 88 F.4th 275 (3d Cir. 2023), has definitively stated that there is no cause of action for a failure to intervene in a medical context. In correctional medicine, the Eighth Amendment to the United States Constitution provides that “[e]xcessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.” With respect to prisoner confinement, the Eighth Amendment obligates the government “to provide medical care for those whom it is punishing by incarceration.” Estelle v. Gamble, 429 U.S. 97, 103 (1976). Thus, for decades those individuals in custody have had a constitutional right to medical care.  Creative plaintiffs’ lawyers have since brought federal civil rights claims seeking to create a cause of action for a failure to intervene against both law enforcement and medical staff personnel, arguing those individuals had a duty to prevent a violation of the right to medical care where medical care was not provided or adequately provided to a person in custody. For years there had been conflicting case law as to whether there was a cause of action for a failure to intervene in the medical context in correctional facilities.  Older authority stood for the proposition that medical providers could not be liable for failing to intervene in situations involving excessive force. See, e.g., Ali v. McAnany, 262 Fed. Appx. 443, 446 (3d Cir. Jan. 25, 2008); Goldsmith v. Franklin County, 2016 WL 6440141, at *7 (M.D. Pa. Sept. 30, 2016) (“[T]he [Third Circuit] has expressly declined to extend its holding in Smith beyond correctional officers to impose a duty to intervene upon medical employees working within a prison setting.”); Harris v. Hershey Med. Ctr., 2009 WL 2762732, at *6 (M.D. Pa. Aug. 27, 2009). In Goldsmith, the District Court explained:  [A]lthough [the Third Circuit in] Smith announced that corrections officers have a legal duty to intervene . . . the court clearly grounded its decision in the fact that a corrections officer, like a police officer, is a law enforcement officer, sworn to uphold the law, and authorized to use force if necessary. 2016 WL 6440141, at *7. Thus, a medical provider has “no legal duty to intervene on behalf of an inmate in the midst of physical altercations with staff.” Id. More recent decisions have been decided differently. District courts have found plausible causes of action for failure to intervene against medical professionals where they have allegedly failed to provide emergency medical care. See Thomas v. Harrisburg City Police Dep’t, 2021 WL 4819312 (M.D. Pa. Oct. 15, 2021) and Cyr v. Schuylkill Cnty., 2023 WL 1107879 (M.D. Pa. Jan. 30, 2023).  The Thomas decision was appealed to the Third Circuit by individual police officers on qualified immunity grounds after their motion to dismiss was denied. See Thomas v. City of Harrisburg, 88 F.4th 275 (3d Cir. 2023). The decedent in Thomas ingested cocaine at the time of his arrest. The plaintiff argued that the arresting police officers had a duty to intervene to prevent the violation of the decedent’s constitutional right to medical care. Specifically, it was alleged that the police officers should not have taken the decedent to the county booking center but, rather, should have taken the decedent to the hospital for evaluation. The police officers argued that they had qualified immunity.  The Third Circuit found that the District Court properly denied the police officers’ motion to dismiss as to the failure to render medical care. However, the Third Circuit held that the District Court erred in denying the motion to dismiss on the failure to intervene claim. The court stated: The Officers contend that the District Court improperly denied their motion to dismiss because (1) Sherelle Thomas cannot adequately plead a violation of failure to intervene to prevent a violation of the right to medical care where no such cause of action exists and (2) there is no clearly established right to intervention in the context of medical care.  The District Court does not directly address whether individuals have a clearly established right to intervention. We agree with the Officers that we have not recognized any such right, nor has the Supreme Court. Though we have recognized a right to have a government actor intervene when the underlying constitutional violation involves excessive force or sexual assault of a person in custody or detention, we have since concluded that our precedent does not establish, let alone clearly establish, a right to intervention in other contexts.  Thomas, 88 F.4th at 285.  Thus, the Third Circuit has definitively stated that there is no cause of action for a failure to intervene in a medical context, and this holding has been followed by at least one subsequent district court case where such a claim was pursued. See Rossman v. PrimeCare Medical, Inc., 2024 WL 115203 (M.D. Pa. Jan. 10, 2024). As such, neither medical professionals nor law enforcement should be required to defend a failure to intervene claim arising from medical care, and these claims should be challenged.

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.
