Bolitho v. City and Hackney Health Authority
Factual and Procedural Background
The case concerns the care given to Patient, a two-year-old boy admitted to The Hospital on 16–17 January 1984 for breathing difficulties attributed to croup. During two acute episodes of respiratory distress (12:40 p.m. and 2:00 p.m. on 17 January), ward staff urgently summoned Doctor A (senior paediatric registrar) and Doctor B (senior house officer). Neither attended. At 2:30 p.m. the child suffered total airway obstruction, cardiac arrest, and catastrophic brain damage. He later died. His mother, acting as administratrix of his estate, sued Company A (the health authority) for negligence.
At first instance, Judge Hutchinson found that the doctors’ failure to attend breached the duty of care. The key outstanding issue was causation—would prompt attendance and intubation have averted the cardiac arrest? After hearing eight expert witnesses, the judge concluded that although many competent doctors would have intubated, a responsible body would not, and Doctor A would not have intubated. He therefore held causation unproved and dismissed the claim. The Court of Appeal (Dillon LJ and Farquharson LJ; Simon Brown LJ dissenting) affirmed. The present appeal to the House of Lords followed.
Legal Issues Presented
- Whether, in an omission case, the Bolam standard governs the hypothetical question of what a doctor should have done for purposes of causation.
- Whether a court may reject a “responsible body” of professional opinion under the Bolam test if that body’s reasoning is illogical or indefensible.
Arguments of the Parties
Appellant's Arguments
- The trial judge misapplied the Bolam test by giving conclusive weight to expert evidence favouring non-intubation, despite its alleged lack of logical foundation.
- Causation should have been determined on ordinary factual proof; professional opinion is irrelevant to what would actually have happened.
- Even if Doctor A would not have intubated, the court should have held that any competent doctor was obliged to do so, making the defendant liable.
Respondent's Arguments
- Causation required proof that a competent doctor attending at the relevant times would have intubated; the evidence showed that a responsible body would not have done so.
- The judge correctly accepted Doctor D’s expert view that intubation was unnecessary given the risks involved and the child’s intermittent recovery.
- The Bolam test applies equally to determining the standard of care when analysing hypothetical actions for causation.
Table of Precedents Cited
| Precedent | Rule or Principle Cited For | Application by the Court |
|---|---|---|
| Bolam v. Friern Hospital Management Committee (1957) | A professional is not negligent if acting in accordance with a practice accepted by a responsible body of peers. | Used to define the standard for judging whether non-intubation would have been negligent. |
| Maynard v. West Midlands Regional Health Authority (1984) | The court may not find negligence merely by preferring one respectable professional opinion over another. | Cited as the guiding statement for the trial judge’s self-direction on expert disagreement. |
| Bonnington Castings Ltd. v. Wardlaw (1956) | Plaintiff bears the burden of proving that the breach caused the injury. | Reiterated the need for the appellant to prove causation despite admitted breach. |
| Wilsher v. Essex Area Health Authority (1988) | Confirms the plaintiff’s burden to establish causation in medical negligence. | Reinforced the causation analysis adopted by the House of Lords. |
| Hucks v. Cole (1968) [1993] 4 Med LR 393 | Court may find negligence where a professional practice exposes patients to grave avoidable risk. | Illustrated that a responsible body’s view can still be rejected if illogical. |
| Edward Wong Finance Co. Ltd. v. Johnson Stokes & Master (1984) | Widespread professional practice may nevertheless be negligent if unreasonable. | Support for the proposition that courts must scrutinise the logic behind expert opinion. |
| Joyce v. Merton, Sutton and Wandsworth HA (1996) | Explained analytical framework where an original fault is followed by hypothetical subsequent negligence. | Quoted to justify the two-stage causation inquiry adopted by the trial judge. |
Court's Reasoning and Analysis
The House of Lords, through the lead speech of Judge Browne-Wilkinson, adopted a two-stage causation test:
- Factual hypothetic: What would Doctor A or Doctor B actually have done had they attended? The trial judge was entitled to accept evidence that neither would have intubated.
- Normative assessment: If the doctors would not have intubated, would that omission itself have fallen below the professional standard? Here the Bolam test applies.
The Law Lords emphasised that the court is not automatically bound by any body of expert opinion; it must be “responsible, reasonable and respectable” and capable of withstanding logical analysis. Nonetheless, rejecting such a body will be rare because medical risk-benefit assessments are primarily clinical judgments.
Applying this framework, the Lords found:
- The trial judge correctly identified and answered both causation questions.
- Doctor D’s evidence that intubation was unwarranted—given the patient’s rapid recoveries and the invasive risks of the procedure—was logically defensible. Consequently, it represented a responsible body of opinion.
- The judge’s personal inclination (“as a layman”) was properly set aside in favour of accepted expert reasoning.
- The Court of Appeal majority had therefore been right to uphold the first-instance decision; the dissenting view misread the judgment by overlooking the distinct factual and normative questions.
Holding and Implications
APPEAL DISMISSED.
The decision confirms the continued application of the Bolam test but clarifies that courts may, in exceptional cases, reject expert consensus that lacks logical coherence. No new cause of action or remedy was created; the immediate effect is that the estate of Patient receives no compensation, and Company A incurs no liability.
