Smart Summary (Beta)

Factual and Procedural Background

This is a claim by the Plaintiff for damages for psychiatric injury (later diagnosed as PTSD) following the negligent administration of a substantial overdose of medication to the Plaintiff's spouse at The Hospital on 20 July 2021. The Hospital admitted negligence in administering the overdose which caused a sudden and catastrophic medical event. The Plaintiff attended The Hospital shortly thereafter, witnessed the immediate aftermath, collapsed in acute distress and subsequently developed psychiatric injury. The dependants' claim under the Civil Liability Act 1961 for the deceased was agreed at €61,368. The central contested issues at trial concerned (i) whether the psychiatric injury was "shock-induced" within the framework of Kelly v Hennessy and thus recoverable as nervous shock, and (ii) whether The Hospital owed a duty of care to the Plaintiff as a relative of a patient.

Legal Issues Presented

Whether the Plaintiff's psychiatric injury was "shock-induced" (a qualifying sudden and horrifying event or its immediate aftermath) within the Kelly v Hennessy framework and therefore actionable as nervous shock.
Whether the overdose and its immediate aftermath constituted an "accident" for the purposes of nervous shock jurisprudence.
Whether The Hospital owed a duty of care to the Plaintiff (a non-patient spouse present at the scene) in the circumstances established.
Quantum: if liability established, the appropriate award for the Plaintiff's PTSD consistent with guidelines and evidence.

Arguments of the Parties

Plaintiff's Arguments

The Plaintiff relied on evidence that he witnessed the immediate and shocking aftermath of the overdose on 20 July 2021, suffered an acute stress reaction then, and later developed PTSD; the traumatic episode was sudden, external and distinct from gradual illness.
The Plaintiff argued that the qualifying criteria in Kelly v Hennessy were met (shock, temporal proximity, close relationship and direct perception) and that The Hospital's continuing control of the situation supported a duty of care to him in these facts.
If liability established, the Plaintiff sought an award consistent with Category 4B(b) serious PTSD and proposed an appropriate figure within the guideline ranges, taking account of age and prognosis.

Defendant's Arguments

The Hospital accepted negligence in the care of the deceased but submitted that the claim for psychiatric injury was not "shock-induced" by a single discrete accident but instead arose from a continuum of events, gradual distress or grief; accordingly Kelly v Hennessy criterion 2 was not met.
The Hospital argued that events arising during diagnosis or treatment (a "medical crisis") are not the kind of external "accident" contemplated by the authorities and relied on Paul and other authorities to contend that no accident occurred in the relevant legal sense.
The Hospital contended that it owed no duty of care to the Plaintiff as a non-patient spouse in these circumstances; extending duty to relatives would conflict with clinical focus, confidentiality and risk indeterminate liability; reliance was placed on principle and on Barlow.

Precedent	Rule or Principle Cited For	Application by the Court
Kelly v Hennessy [1995] 3 IR 253	The framework and criteria for recovery for nervous shock (including requirement of a sudden shocking event, proximity in time and perception, relationship and reasonableness of imposing duty).	The Court applied the Kelly v Hennessy controls to assess whether the overdose and its immediate aftermath constituted a qualifying shock and whether a duty of care arose to the Plaintiff; the Court found the criteria were satisfied in the present facts.
Jaensch v. Coffey [1984] 155 CLR 549	Example of recovery where psychiatric illness developed from what was seen/heard at hospital; Brennan J's analysis shaping nervous shock claims.	The Court treated Jaensch as part of the mould for nervous shock claims and cited it in support of recovery where a close relative suffered psychiatric injury from hospital scenes following defendant-caused injury to another.
Byrne v Great Southern and Western Railway Co of Ireland (1884) (summarised in Bell v Great Northern Railway Co. of Ireland (1890) 26 L.R. Ir 428)	Historical recognition that nervous shock may be compensable where a person suffers a great fright from a sudden traumatic event even without physical injury.	Referred as part of the historical development of the law recognizing recovery for nervous shock from sudden external events.
Bell v Great Northern Railway Co. of Ireland (1890) 26 L.R. Ir 428	Jury award for nervous shock resulting from witnessing or perceiving a traumatic railway disaster; used historically to justify recovery.	Referred in the historical survey supporting that the law has long recognised recovery for sudden shocking events causing nervous shock.
Courtney v. Our Lady Hospital Crumlin and Others [2011] IEHC 226 [2011] 2 IR 786 [2011] 2 ILRM 328	Recovery awarded for significant psychiatric illness caused by trauma in a hospital setting (failure to diagnose meningitis leading to death).	The Court noted Courtney as an Irish instance where psychiatric injury arising from hospital events led to substantial damages and observed that exclusion of hospital events had not been argued there.
Barry v. Health Service Executive and Mercy University Hospital (unreported judgment of 16 December 2015) [2015] IEHC 791	Award for psychiatric injury to a close partner owing to admitted hospital negligence leading to death; facts involved distress over a period.	Cited as an Irish precedent where hospital negligence led to awards for psychiatric injury without invocation of Kelly v Hennessy criteria in the reported account.
Morrissey v. H.S.E. [2019] IEHC 268	Consideration of duty of care in cases of witnessing deterioration following negligent screening; examined whether a duty was owed to close relatives.	Used to contrast deterioration/misdiagnosis cases where courts found no duty to relatives; distinguished from the present sudden overdose.
Mitchell v. H.S.E. [2023] IEHC 394	Similar factual area to Morrissey about negligent screening leading to disturbing events; considered relevance of prior authority on duty.	Referred as part of jurisprudence on deterioration cases and whether Morrissey binds other judges; distinguished from the instant sudden-overdose facts.
Germaine v. Day [2024] IEHC 420	Claim based on witnessing gradual deterioration after a missed radiological finding; difficulty satisfying Kelly v Hennessy criteria for sudden shock.	The Court distinguished Germaine's gradual deterioration facts from the immediate catastrophic overdose in this case and noted Germaine did not canvas whether a missed diagnosis could be an "accident".
Fletcher v. Commissioners of Public Works [2003] 1 IR 464	Authority where fear of future illness from past exposure was insufficient; Geoghegan J's statement that Kelly should be confined to accident damage was cited.	Relied upon by The Hospital to argue nervous shock jurisprudence should be limited to accident damage; the Court addressed and distinguished that point in light of the overdose facts.
Harford v. ESB [2021] IECA 112 [2022] 2 IR 541	Decision emphasising requirement for a sudden horrifying event and distinguishing intrusive thoughts absent a horrifying event.	The Hospital relied on Harford to support the proposition that no horrifying event occurred; the Court considered Harford and concluded the overdose was a qualifying sudden event.
Paul and Another v. Royal Wolverhampton NHS Trust [2024] UK SC 1 [2025] AC 459	UK Supreme Court consideration whether witnessing death/injury from medical conditions negligently undiagnosed permits nervous shock claims; distinguished medical crisis from accident.	The Hospital relied on Paul to argue no accident occurred; the Court noted differences in legal taxonomy between jurisdictions, that Paul confined itself to medical crisis following diagnosis, and that Paul expressly left open examples like a wrong injection scenario; the Court declined to follow Paul's limitation here.
Devlin v. National Maternity Hospital [2008] 2 IR 22	Authority on temporal proximity and the requirement for immediacy in nervous shock claims.	Referred in discussing temporal proximity and in distinguishing cases that failed for lack of immediacy from the present case where immediacy was established.
Donoghue v Stevenson [1931] AC 562	Foundational principle of proximity and reasonable foreseeability in duty of care.	The Court invoked Donoghue v Stevenson to ground proximity as part of the duty analysis and to explain the legal basis for finding a duty in these specific facts.
Barlow, Woodstown Bay Shellfish Limited and Others v. The Minister for Communications, Marine and Natural Resources and Others [2025] IESC 14	Discussion of assumption of responsibility and limitations on extending duty of care in claims against State-controlled entities.	The Hospital cited Barlow to argue that assumption of responsibility and extension of duty to relatives would be inappropriate; the Court considered but held it need not base its duty finding on assumption of responsibility.
Hedley v. Byrne	Principle concerning assumption of responsibility in negligent misstatement leading to economic loss.	Referred in the context of discussion about assumption of responsibility and its limited scope; the Court did not base its decision on Hedley-type assumption.
Victorian Railway Commissioners v Coultas (1883) 13 App Cas. 222	Historic authority referenced in the common law history of nervous shock cases.	Referred in the historical account of how courts treated fright and shock in early jurisprudence.
Re: Worldport Ireland Ltd. (in liquidation) Unreported, High Court, 16 June 2005 [2005] IEHC 189	Authority cited concerning binding nature of earlier High Court determinations.	Mentioned in relation to discussion of whether prior findings bind judges of equal jurisdiction in later cases (contextual reference in the survey of authority).

Court's Reasoning and Analysis

The Court proceeded by applying the Kelly v Hennessy framework and the established controls (shock, temporal proximity, relationship/proximity and reasonableness of imposing a duty). The key analytical steps were:

The Court characterised "accident" as a sudden, unintended and externally caused event capable of producing a direct and shocking sensory impact; the setting (hospital) is not decisive—the character of the event is.
The overdose was found to be an external, discrete and catastrophic event (not simply part of illness progression or ordinary clinical discretion) and therefore capable of constituting an "accident" for nervous shock purposes.
The Court accepted uncontroverted expert evidence that the Plaintiff experienced an acute stress reaction on 20 July 2021 which later developed into PTSD; the immediate reaction (including collapse) established temporal proximity and that the injury was shock-induced rather than merely grief or gradual distress.
The Court analysed duty of care focusing on legal proximity created by contemporaneity and The Hospital's continuing control of the situation: negligence caused the overdose; the Plaintiff arrived promptly, directly perceived the ongoing physical manifestations, suffered immediate physical collapse and the hospital retained control while managing the crisis.
The Court distinguished cases about gradual deterioration or diagnostic omissions (e.g., Germaine, Morrissey, Mitchell) and considered but did not apply the restrictive approach advanced from Paul, noting differences in legal taxonomy and that Paul left open examples akin to the present facts.
The Court concluded that recognising a duty in these specific facts did not amount to a general duty owed by hospitals to relatives nor did it constitute an impermissible expansion of liability; it applied established principles to a factual matrix where proximity, foreseeability and a qualifying shock were present.

Holding and Implications

Holding: THE PLAINTIFF'S CLAIM FOR NERVOUS SHOCK IS SUSTAINED. The Court awarded general damages of €40,000 for the Plaintiff's PTSD and the agreed sum of €61,368 under the Civil Liability Act 1961 for the statutory dependants' claim.

Implications: The Court confined its decision to the specific facts: a sudden, defendant-caused overdose in hospital, immediate temporal proximity, direct perception by the Plaintiff and The Hospital's continuing control of the situation. The judgment recognises a duty of care to a close relative in such narrowly defined circumstances but does not recognise a general duty on healthcare providers to all relatives of patients or purport to overturn binding authority; no broader categorical rule was established beyond the factual confines described.
