New Connecticut Precedent: A Mental Health Provider Owes a Limited Duty to an Identifiable Nonpatient When the Provider Actually Knows of a Substantial Risk of Imminent Physical Harm

Case: Ashworth v. Branford, Supreme Court of Connecticut (SC 21175) (officially released Aug. 4, 2026)

1. Introduction

Ashworth v. Branford arises from the killing of Caroline Anne Ashworth by Michael Mollow shortly after Mollow’s involuntary psychiatric hospitalization and discharge. The plaintiff, Angela Ashworth (administratrix of the estate), sued SVMC Holdings, Inc. (operator of St. Vincent’s Medical Center’s psychiatric hospital) alleging, among other things, negligent failure to control Mollow and/or warn the decedent—an identifiable target—of the danger posed by Mollow following discharge.

The key issues were (i) classification: whether counts two through six sounded entirely in medical malpractice (thus barred because the decedent was a nonpatient under Jarmie v. Troncale), or whether they included ordinary negligence theories; and (ii) duty: whether Connecticut recognizes a common-law duty owed by a mental health care provider to an identifiable nonpatient victim when the provider has actual knowledge of a substantial risk of imminent physical harm posed by the patient.

2. Summary of the Opinion

The court held the trial court erred by striking counts two through six in their entirety. Construed broadly, some allegations sounded in ordinary negligence rather than medical malpractice because they challenged SVMC’s response to a known, substantial risk of imminent harm to an identifiable victim (e.g., failure to warn the decedent; failure to take reasonably necessary steps to control Mollow; and allegations of premature discharge framed as non–medical-judgment failures to mitigate known danger).

The court reaffirmed that allegations challenging diagnosis, treatment, medication management, risk assessment, and discharge planning require professional medical judgment and therefore sound in medical malpractice (and, under Jarmie v. Troncale and General Statutes § 52-190a, cannot be pursued by a nonpatient).

New rule (first impression): A mental health care provider who actually knows a patient poses a substantial risk of imminent physical harm to an identifiable nonpatient owes that nonpatient a duty to take reasonable steps to protect them, which may include warning the nonpatient or controlling the patient.

The court declined to review the gross medical negligence claim (count seven) as inadequately briefed.

3. Analysis

3.1. Precedents Cited

  • Jarmie v. Troncale (306 Conn. 578): The pivotal procedural/substantive backdrop. Jarmie interpreted § 52-190a to mean a “cause of action alleging medical malpractice must be brought by a patient” because negligence must occur “in the care or treatment of the claimant.” In Ashworth, this remained a decisive barrier for allegations sounding in malpractice. But Ashworth narrows the practical reach of Jarmie by emphasizing that not all provider misconduct is malpractice; some can be ordinary negligence if it does not implicate medical judgment.
  • Doe v. Cochran (332 Conn. 325): The court’s template for permitting nonpatient ordinary negligence claims against providers where the alleged negligence does not require professional medical judgment (there: misreporting STD results). Ashworth imports Doe’s distinction—acts “within the ken of a layperson”—to the post-knowledge response to a known imminent threat.
  • Fraser v. United States (236 Conn. 625): The court treated Fraser as an earlier, careful refusal to recognize a broad duty in a case involving an outpatient “not known to have been dangerous” and a victim “neither readily identifiable nor within a foreseeable class.” In Ashworth, Fraser becomes the negative space that supports a positive rule: duty is most plausible when the victim is identifiable and the risk is known and imminent.
  • Tarasoff v. Regents of the University of California (17 Cal. 3d 425): Not adopted wholesale, but used to frame the national debate and to illustrate a common duty formulation: reasonable care to protect an intended victim once a serious danger is recognized. Ashworth aligns more closely with the narrower “actual knowledge” approach discussed in the opinion’s treatment of Tarasoff’s history and limits (including California’s statutory narrowing).
  • Gold v. Greenwich Hospital Assn. (262 Conn. 248) and Levin v. State (329 Conn. 701): Both distinguished. In Gold, the plaintiff’s claim implicated “medical judgment in discharging” the patient, sounding in malpractice. In Levin, the matter was authorized and pursued as medical malpractice (and thus barred for a nonpatient under Jarmie), and ordinary negligence was not in play. Ashworth uses these cases to show that where the core dispute is “should the provider have assessed/diagnosed differently,” it is malpractice; where the dispute is “what reasonable steps were taken after actual knowledge,” it may be ordinary negligence.
  • Jacoby v. Brinckerhoff (250 Conn. 86) and Gazo v. Stamford (255 Conn. 245): Cited to show Connecticut’s repeated (though sometimes dicta-adjacent) recognition that a duty to disclose substantial risk of imminent violence arises only for an identifiable victim/class, and that policy limits duty scope. Ashworth converts that line of discussion into an express holding for the mental health provider context.
  • Kaminski v. Fairfield (216 Conn. 29): Used to address SVMC’s argument that no warning was required because the decedent “already knew” the danger. The court distinguished Kaminski on the pleadings: prior awareness of past threats is not necessarily knowledge of the escalated risk at hospitalization/discharge, especially where the provider possessed more particularized, contemporaneous information.
  • Squeo v. Norwalk Hospital Assn. (316 Conn. 558): Addressed only to the extent it was invoked for count seven. The court did not reach the merits because the claim was inadequately briefed.

3.2. Legal Reasoning

A. Sorting malpractice from ordinary negligence

The opinion’s engine is a refined classification rule: allegations are malpractice when they require judging professional medical judgment in diagnosis/treatment/risk assessment/discharge planning, typically demanding expert testimony; allegations are ordinary negligence when, after the provider has already reached the clinical conclusion that an imminent danger exists, the alleged breach is a failure to take reasonable protective steps that do not themselves turn on medical judgment.

The court explicitly contrasted “should have known / had reason to know” allegations (malpractice, because they attack the adequacy of the provider’s professional assessment) with “actually knew” allegations (potentially ordinary negligence, because the risk determination is assumed and the question becomes the reasonableness of the response).

Applying this, the court held the following were ordinary-negligence-sounding allegations:

  • Failure to take reasonably necessary actions to control Mollow to prevent harm to or killing of the decedent.
  • Failure to use proper and available resources to contact and warn the decedent of Mollow’s homicidal ideations directed at her.
  • Premature discharge before the fifteen-day emergency certificate period expired, construed broadly as a non–medical-judgment failure to mitigate a known danger.

And the following were malpractice-sounding allegations (barred for a nonpatient by § 52-190a and Jarmie):

  • Failure to contact collateral sources to verify information; inadequate risk assessment; failure to assess effects of alcohol/Xanax use.
  • Failure to treat intrusive thoughts; medication titration errors; release “under his own care”; failures framed as clinical assessment and planning.
  • Failure to determine how Mollow would act upon discharge if he saw the decedent (treated as part of clinical assessment).

B. Recognizing a limited duty to identifiable victims (first impression)

After identifying non-malpractice allegations, the court reached duty. It reaffirmed the baseline: no duty to protect others from third-party conduct absent a special relationship or special circumstances. Then it held that, when a mental health care provider actually knows of a patient’s substantial risk of imminent physical harm to an identifiable third party, public policy supports imposing a duty to take reasonable protective steps, including warning and/or control.

C. Statutory alignment and policy balancing

The court anchored the duty in legislative policy rather than treating it as a judicial intrusion:

  • General Statutes § 17a-502 (emergency involuntary commitment): The statutory authorization to confine dangerous persons reflects a legislative recognition that preventing harm to “others” can justify significant liberty intrusions, supporting (not undermining) a duty to act reasonably when danger to an identifiable victim is known.
  • (Supp. 2026) §§ 52-146d through 52-146j, especially (Supp. 2026) § 52-146f (2) (confidentiality exception): The exception permitting disclosure when the provider determines a “substantial risk of imminent physical injury” shows legislative acceptance that confidentiality yields in acute danger situations. The duty recognized does not expand the statutory disclosure conditions; it operates within the same policy balance.

The court rejected “floodgates,” hindsight, and defensive-medicine arguments by emphasizing the duty’s narrow trigger: it arises only with actual knowledge, substantial risk, imminence, and a specifically identifiable victim.

D. Relationship to the Restatements

The complaint pleaded Restatement-based theories (Restatement (Second) of Torts §§ 315 and 319; Restatement (Third) of Torts, Liability for Physical and Emotional Harm § 41). While the opinion did not adopt these sections as a formal rule of decision, it used their conceptual framework—special relationships and custody/control—to situate the duty analysis and to show consistency with broader tort principles recognized in other jurisdictions.

3.3. Impact

  • Pleading and motion-to-strike practice: Plaintiffs representing nonpatients will likely draft around § 52-190a and Jarmie by pleading (where supported) actual knowledge of a substantial imminent threat to an identifiable victim, and focusing on failures to warn or to take non–medical-judgment protective steps.
  • Operational effects for psychiatric facilities: Facilities may strengthen documentation and protocols around (i) identification of specific threatened victims, (ii) efforts to warn, and (iii) nonclinical process controls (communications, coordination, and discharge mechanics), because the duty is evaluated under ordinary negligence once the clinical danger determination is assumed.
  • Doctrinal clarification: Ashworth is a major refinement of Connecticut’s provider-duty jurisprudence after Jarmie and Doe, confirming that nonpatient claims are not categorically barred, but can proceed when they do not require second-guessing professional medical judgment.
  • Limits preserved: The opinion does not create broad third-party liability for patient violence; it does not impose a generalized duty to predict violence; and it does not disturb statutory constraints on commitment/discharge or confidentiality.

4. Complex Concepts Simplified

  • Medical malpractice vs. ordinary negligence: Malpractice claims ask whether the provider’s professional clinical judgment (diagnosis/treatment/risk assessment) met professional standards; ordinary negligence asks what a reasonable person would do, typically about nonclinical acts once the relevant risk is already known.
  • “Actual knowledge” vs. “should have known”: “Actual knowledge” means the provider in fact recognized a substantial, imminent threat; “should have known” alleges the provider failed to recognize the threat and therefore challenges clinical judgment (malpractice).
  • “Identifiable victim”: Not the public at large; a specific person (or a narrow, readily identifiable class) whom the provider knows is the target of the patient’s threatened or imminent violence.
  • “Substantial risk of imminent physical harm”: More than a vague possibility; a serious, near-term threat of physical injury. The duty is keyed to imminence and seriousness, limiting hindsight-based liability.
  • Emergency certificate under § 17a-502: A physician may involuntarily commit a person for up to fifteen days when the person has psychiatric disabilities and is dangerous to self/others or gravely disabled, with statutory safeguards and required psychiatric review.
  • Motion to strike: A pleading-stage challenge; the court assumes the complaint’s well-pleaded facts and decides whether, if proven, they state a legally cognizable claim.

5. Conclusion

Ashworth v. Branford establishes a consequential, tightly cabined Connecticut duty: when a mental health care provider actually knows a patient poses a substantial risk of imminent physical harm to an identifiable nonpatient, the provider owes that person a duty to take reasonable protective steps, including warning and/or control. At the same time, the court preserves Jarmie v. Troncale’s bar on nonpatient medical malpractice claims under § 52-190a by carefully separating malpractice (clinical judgment) from ordinary negligence (post-knowledge protective action). The decision is best understood as both an expansion (recognizing a third-party duty in a defined scenario) and a limitation (requiring actual knowledge, imminence, substantiality, and identifiability), positioning Connecticut in line with the prevailing, restrained approach to Tarasoff-type liability.
