Doctor Sudhir Mohun and Another v Advocate Brett Kingsley Phillips N O obo Shearer and Another

On 27 December 2014, Mr David Robin Shearer (aged 43) was admitted to the emergency unit of Life Westville Hospital after consuming an unknown quantity of tablets combined with alcohol. He was examined by the first appellant, Dr Sudhir Mohun, a specialist physician engaged as a locum tenens by the second appellant, a medical practice (Doctors G Sanpersad, R Maharaj & Associates) that provided clinical care in the emergency unit. On admission at 21h30, Mr Shearer was triaged as orange with an oxygen saturation level of 93%. Dr Mohun examined him at 21h35, finding him haemodynamically stable with clear chest, cardiovascular system and abdomen. Mr Shearer was given 40% oxygen via facemask. Dr Mohun left Mr Shearer in the care of nursing staff. By 21h45, Mr Shearer's oxygen saturation had dropped to 82%. At 22h00 he was found unresponsive and pale. At approximately 22h05 he suffered cardiac arrest with oxygen saturation at 28%. Resuscitation was undertaken until 22h30, after which he was intubated and transferred to ICU at 22h40. Mr Shearer sustained permanent brain damage as a result of hypoxia and cardiac arrest. The respondents sued both appellants for damages arising from alleged negligent conduct.

• Whether the first appellant (Dr Mohun) was negligent in failing to appropriately monitor and treat Mr Shearer
• Whether the first appellant breached his duty of care by leaving Mr Shearer in the care of nursing staff without adequate instructions or monitoring
• Whether causation was established between the alleged negligence and the brain damage suffered
• Whether the second appellant (medical practice) could be held vicariously liable for the conduct of the first appellant who was an independent contractor
• Whether the common law should be developed to recognize a non-delegable duty of care in circumstances where the victim was especially vulnerable (such as in hospitals)

1. The appeal of the first appellant (Dr Mohun) was dismissed with costs. 2. The appeal of the second appellant (medical practice) was upheld with costs. 3. The first appellant was found liable for 65% of whatever damages Mr Shearer might prove for injuries sustained as a result of the cardiac arrest and resultant brain damage. 4. The first appellant was ordered to pay the first plaintiff's costs of suit (though costs for two counsel were disallowed on appeal). 5. The claims of the second plaintiff (Mrs Shearer) in her personal capacity and on behalf of minor children were postponed sine die to be determined together with quantum. 6. The action against the second appellant (medical practice) was dismissed with costs.

1. A medical practitioner who admits a patient presenting with drug and alcohol overdose has a duty to continuously monitor that patient or ensure adequate monitoring, even where the patient initially appears stable, because the absorption of intoxicants into the system creates a foreseeable risk of gradual deterioration in breathing and oxygenation. 2. It is insufficient for a medical practitioner to delegate monitoring to nursing staff without providing clear written instructions as to what must be monitored, particularly where detecting relevant changes requires specialized medical knowledge to identify subtle indicators such as changes in breathing rate, depth, and airway maintenance. 3. Where a medical practitioner's negligent failure to monitor or provide adequate instructions results in a patient suffering hypoxia and cardiac arrest that could have been prevented by timeous intervention, causation is established. 4. A principal is not vicariously liable for the delicts of an independent contractor except where the principal was personally at fault - this principle applies to medical practices that engage locum tenens doctors as independent contractors. 5. Before developing the common law, a litigant must establish: (a) the existing common law position and its underlying reasons; (b) how it offends the Bill of Rights; (c) precisely how it should be amended; and (d) the wider consequences of the proposed change. Such arguments should ordinarily be raised at first instance.

The Court made several obiter observations: (1) It questioned how the high court determined the 65% apportionment of liability but noted this was not before the Court on appeal. (2) The Court noted that calling Mrs Shearer as a witness would not have advanced the case given Prof Coetzee's evidence was based on hospital records and clinical notes, and the first appellant's own concessions. (3) The Court observed that the appeal of the first appellant concerned an uncomplicated factual issue that did not reasonably warrant employment of two counsel, and therefore disallowed such costs. (4) The Court noted that in appropriate cases, courts may allow constitutional development arguments to be raised on appeal or even mero motu, but emphasized this was not such a compelling or exceptional case. (5) The Court implicitly observed that Chartaprops represents recent binding precedent on the vicarious liability of principals for independent contractors, and any reconsideration would require a clearly set out basis with full argument on constitutional development requirements.

This case is significant in South African delictual law for: (1) Clarifying the standard of care required of medical practitioners in emergency settings where patients present with drug and alcohol overdose - continuous monitoring is required even where patients initially appear stable. (2) Emphasizing that delegation to nursing staff does not absolve a medical practitioner of the duty of care where the practitioner's specialized knowledge is required to detect subtle changes in patient condition. (3) Confirming the established principle that principals are not vicariously liable for the delicts of independent contractors (following the majority in Chartaprops). (4) Setting out the rigorous requirements for developing the common law, including that such arguments should be raised at first instance and must comprehensively address: the existing legal position, its underlying reasons and deficiencies, how it deviates from constitutional values, how it should be rectified, and the wider consequences of proposed changes. (5) Declining to develop a doctrine of non-delegable duty of care in the medical context without proper foundation being laid.
