Wisniewski (A Minor) v Central Manchester Health Authority

Factual and Procedural Background

This appeal concerns a medical negligence claim brought by the Plaintiff, a minor, against the Defendant health authority. The Plaintiff was born with athetoid cerebral palsy, attributed to irreversible brain damage sustained during the 13 minutes immediately prior to birth due to strangulation caused by the umbilical cord being wrapped around his neck with a knot. The Plaintiff's mother was admitted to a major teaching hospital in the early hours of the day of birth, where monitoring revealed signs of fetal distress. The trial judge found that negligent mismanagement by the Defendant, specifically the failure of the attending doctor to examine the mother and intervene promptly following an early deceleration in the fetal heart rate at 3:40 am, led to the injury. Damages were agreed, and the trial judge’s focus was on liability. The Defendant appealed the liability finding.

The trial judge made detailed findings about the hospital staff involved, including the midwife sister and the resident senior house officer (SHO) on duty, noting the latter’s failure to attend or examine the mother at a critical time. The SHO did not give evidence at trial, having relocated abroad, and the judge drew adverse inferences from this absence. The appeal raised issues including the application of the legal standard for medical negligence, the drawing of adverse inferences from the SHO’s failure to give evidence, and causation.

Legal Issues Presented

1. Whether the trial judge erred in substituting his own assessment of the appropriate medical standard of care over that of a responsible body of medical opinion, contrary to the principles affirmed in Bolitho v City and Hackney Health Authority.
2. Whether the judge was entitled to draw an adverse inference from the SHO’s failure to attend trial and give evidence on what he would have done if he had attended the patient at 3:40 am.
3. Whether the Defendant’s breach of duty was the effective cause of the Plaintiff’s injury, given the nature of the harm sustained during birth.

Arguments of the Parties

Appellant's Arguments

• The Defendant contended that there was a respectable body of medical opinion supporting a "wait and see" approach at 3:40 am, thus the judge improperly substituted his own judgment for that of responsible medical practitioners.
• They argued that the SHO’s absence at trial was justified, and no adverse inference should have been drawn, as the SHO was known to be unavailable and there was no evidence adduced to show what he would have done if he had attended.
• The Defendant challenged causation, asserting that the injury caused by strangulation during birth was different from the risk created by the alleged negligence and thus the breach was not the effective cause of the damage.

Respondent's Arguments

• The Plaintiff maintained that the early deceleration at 3:40 am required immediate investigative intervention, specifically an artificial rupture of membranes (ARM), which would have revealed meconium and prompted a cesarean section, preventing injury.
• The Plaintiff argued that the SHO’s failure to attend trial justified an adverse inference that he would have acted negligently and not taken appropriate steps.
• Regarding causation, the Plaintiff asserted that the risk of hypoxic injury was foreseeable and that the Defendant’s breach was the effective cause of the injury, notwithstanding the precise mechanism of harm was not foreseeable.

Court's Reasoning and Analysis

The court carefully analyzed the trial judge’s application of the Bolitho principles, noting that while the judge found the Plaintiff’s expert evidence compelling, he also acknowledged the existence of a responsible body of medical opinion supporting the Defendant’s approach. The court held that the judge was correct not to reject the Defendant’s expert evidence outright, as it was logically supportable and represented a responsible medical opinion. Thus, the judge erred in concluding that no responsible doctor would have adopted the "wait and see" approach.

Regarding the SHO’s absence, the court affirmed the judge’s adverse inference. The SHO was a material witness who failed to attend trial without adequate justification, and the Plaintiff had adduced a prima facie case on what the SHO would have done if he had attended. The court emphasized that in the modern era, technology such as video-link evidence could and should be used to secure testimony from unavailable witnesses. The Defendant’s failure to call the SHO or arrange for his evidence justified the inference drawn.

On causation, the court agreed with the trial judge’s common sense approach that the Defendant’s breach exposed the Plaintiff to a foreseeable risk of hypoxic injury, and the actual injury, though caused by a rare event (a true knot in the umbilical cord), was within the scope of foreseeable harm. The court rejected any argument that the breach was merely an occasion rather than an effective cause of the injury.

Holding and Implications

The Court of Appeal DISMISSED the Defendant’s appeal, affirming the trial judge’s finding of liability against the Defendant health authority.

The direct consequence is that the Defendant remains liable for the Plaintiff’s injury, and the agreed damages are to be paid accordingly. The court’s decision reinforces the principle that judges may draw adverse inferences from the failure of material witnesses to attend trial without good reason, especially when a prima facie case has been made. It also confirms the application of the Bolitho test as a balanced approach requiring logical scrutiny of medical opinions rather than wholesale judicial substitution of clinical judgment. No new precedent was set beyond applying established principles to the facts.
