Mrs Johanna Cecilia Erasmus underwent a laparoscopic sterilisation operation on 21 January 1999 at Tygerberg Hospital, performed by Dr Du Plessis (second appellant), a clinical assistant employed by the Western Cape Department of Health. The doctor negligently occluded the patient's round ligaments instead of her fallopian tubes, meaning she was not actually sterilised. She fell pregnant soon thereafter, and when this was confirmed in April 1999 (about 8 weeks into pregnancy), the hospital offered termination, which she and her husband refused for religious reasons. The pregnancy appeared uneventful until 5 November 1999 when she was admitted for high blood pressure. An emergency Caesarean section was performed due to foetal distress. The baby did not survive. Either shortly before, during, or after the Caesarean section, Mrs Erasmus developed amniotic fluid embolism (AFE), an extremely rare and unpredictable complication occurring in approximately 1 in 8,000 to 30,000 deliveries. The AFE caused severe haemorrhaging and cardiac arrest, leading to brain anoxia and irreversible brain damage, leaving Mrs Erasmus in a permanent vegetative state. The respondent was appointed as curator ad litem for Mrs Erasmus and brought a delictual claim against the Premier of the Western Cape and Dr Du Plessis.
The appeal was dismissed with costs. The judgment of the Western Cape High Court holding the appellants liable for such damages as the respondent may prove was upheld.
The binding legal principles established are: (1) Under the relative/concrete approach to negligence, it is sufficient that the general nature of the harm and the general manner in which it occurred were reasonably foreseeable; precise foreseeability of the exact mechanism of harm is not required. Pregnancy as a consequence of failed sterilisation is foreseeable, and pregnancy carries foreseeable risks of various complications. Even a rare complication like AFE falls within the general category of foreseeable pregnancy-related complications. (2) Foreseeability operates differently as a criterion for negligence versus legal causation/remoteness. In the context of remoteness, foreseeability means foreseeability of the actual harm, not merely harm of a general kind. (3) For a plaintiff's conduct to constitute a novus actus interveniens breaking legal causation, it must be unreasonable. A refusal of abortion based on religious convictions, where the unwanted pregnancy resulted from the defendant's negligence and no medical contraindications to continuing the pregnancy were advised, is not unreasonable. (4) The flexible test for remoteness of damage requires courts to apply traditional criteria (foreseeability, directness, etc.) flexibly, guided by policy considerations of what reasonable and fair-minded people, including judges, would regard as just. (5) A defendant whose wrongful conduct caused harm cannot escape liability by arguing that the harm might have occurred anyway from other causes. (6) A complication that is rare but known to medical science and has occurred before is not so remote as a 'freakish occurrence' to break legal causation, particularly where it falls within a category of generally foreseeable harms.
The court made several non-binding observations: (1) The court noted that there had been historical debate about whether South African law follows the relative/concrete versus absolute/abstract approach to negligence, but stated it is now widely accepted that courts have adopted the relative approach as a broad guideline 'without applying that approach in all its ramifications.' (2) Brand JA observed that the content of the foreseeability criterion in the context of legal causation is not clearly defined in South African law. (3) The court noted that factual causation established by the 'but for' test is not eliminated by the intervention of another factual cause (the refusal of abortion) - multiple factual causes can coexist. (4) The court distinguished cases like S v Bochris Investments, Sea Harvest Corporation, and Mkhatswa v Minister of Defence where consequences were held too remote, noting those involved truly 'freakish occurrences' that had never happened before. (5) The court observed that if the plaintiff's conduct does not break factual causation, it may still interrupt legal causation, but this depends on the facts of the particular case even where the conduct is unreasonable.
This case is significant in South African delict law for several reasons: (1) It addresses an unusual factual scenario in medical negligence - not the typical 'wrongful birth' claim for child-rearing expenses following failed sterilisation, but rather catastrophic harm to the mother during the birth process. (2) It clarifies the application of the relative/concrete approach to negligence, confirming that reasonable foreseeability requires only the general nature of harm and general manner of occurrence to be foreseeable, not the precise mechanism. (3) It distinguishes between foreseeability as a criterion for negligence versus foreseeability in the context of legal causation/remoteness, holding that the latter requires foreseeability of actual harm rather than just harm of a general kind. (4) It applies the flexible test for remoteness of damage, confirming that traditional tests like foreseeability and directness remain relevant as 'pointers' but must be applied flexibly to achieve fair and reasonable results. (5) It clarifies the law on novus actus interveniens in the context of plaintiff conduct, holding that a religiously-motivated refusal of abortion following negligent failed sterilisation is not unreasonable conduct that breaks the causal chain. (6) It extends medical practitioner liability to rare and unforeseeable complications of pregnancy where the pregnancy itself resulted from medical negligence, provided the complication is not a completely 'freakish occurrence' unknown to medical science.
