How to Prove Medical Negligence in South African Law

To prove medical negligence in South African law, the claimant must establish four elements of the law of delict: (1) a duty of care owed by the practitioner or institution to the patient, (2) breach of the standard of care expected of a reasonably competent medical professional in the same circumstances, (3) causation — both factual and legal — linking the breach to the harm, and (4) damages. These elements are set out in South African common-law authority such as Van Wyk v Lewis 1924 AD 438 and Administrator, Natal v Edouard 1990 (3) SA 605 (D), and in almost every case must be proved on expert evidence. Where the nature of the injury is eloquent — for example a swab retained after surgery — the res ipsa loquitur doctrine allows a court to draw the inference of negligence. Pleadings are issued in the High Court division with jurisdiction over the place where the harm occurred or the practitioner practises.

The Doctrinal Framework: What a Medical Negligence Claim Is at Common Law

South African medical negligence is governed by the general law of delict — the body of common law dealing with wrongful, blameworthy conduct that causes harm — not by a single dedicated statute creating the cause of action. The landmark decisions that shape every modern claim are:

• Van Wyk v Lewis 1924 AD 438 — the foundational Appellate Division authority on the standard of care expected of a medical practitioner.
• Administrator, Natal v Edouard 1990 (3) SA 605 (D) — confirming the duty of care owed by a healthcare institution in a controlled professional environment.

Several statutes sit alongside this common-law framework and regulate specific aspects of the practitioner–patient relationship, the running of healthcare institutions, and statutory duties owed to patients. They do not displace the delictual cause of action; they supplement it.

Statute	Role in a Medical Negligence Claim
Health Professions Act 56 of 1974	Governs registration, fitness to practise, and the professional conduct of medical practitioners, and sets up the Health Professions Council of South Africa (HPCSA).
National Health Act 61 of 2003	Sets out users’ rights, the duties of health establishments, and procedural obligations (consent, emergency care, complaints procedures).
Medical Schemes Act 131 of 1998	Regulates medical schemes and the cover they provide; relevant to funding of treatment and to subrogated recovery actions.
Mental Health Care Act 17 of 2002	Imposes additional statutory duties in the mental-health context, including assisted care and the rights of users.

The Four Elements You Must Prove

Every medical-negligence claim, however complex, is decided by reference to four cumulative elements. The claimant bears the evidentiary burden in respect of each, on a balance of probabilities.

1. Duty of care — owed by the practitioner (doctor, nurse, dentist, or other registered professional) or the institution (hospital or clinic) to the patient. The duty arises from the professional relationship and, as confirmed in Edouard, from the controlled environment in which the institution provides care.
2. Breach of the standard of care — failure to act as a reasonably competent practitioner in the same circumstances would have acted. The test is objective, set by reference to the standard of the relevant specialty and the profession’s accepted practice (including HPCSA guidelines and specialist society protocols).
3. Causation (factual and legal) — the breach must be a necessary condition of the harm (the but-for test, as developed in International Shipping Co (Pty) Ltd v Bentley 1990 (1) SA 680 (A)), and the harm must not be too remote from the breach. Where multiple sufficient causes exist, the test is applied flexibly so as not to non-suit a deserving plaintiff.
4. Damages — quantifiable harm: bodily injury, psychological harm, past and future medical expenses, past and future loss of earning capacity, pension diminishment, and general damages for pain, suffering and loss of amenities of life.

Step-by-Step Process for Proving the Claim

The claim is built on documents first, expert evidence second. The following sequence reflects how these matters are typically run from the claimant’s side.

1. Gather the medical record. Obtain the full set of clinical notes, consent forms, theatre registers, radiological imaging reports, and discharge summaries from every practitioner and institution involved.
2. Confirm the practitioner and institution. Identify the responsible parties and verify their professional registration with the HPCSA or the relevant council.
3. Obtain an expert medical opinion. Secure a written opinion from an independent specialist in the same field confirming (a) the accepted standard of care, (b) the departure from that standard, and (c) the causal link to the injury.
4. Quantify damages. Instruct a forensic accountant or actuary to project past and future loss of earnings, future medical costs, and pension diminishment, supported by payslips, tax returns, invoices and receipts.
5. Issue a letter of demand. Send a formal demand to the practitioner, the institution and their professional indemnity insurer identifying the claim, the legal basis and the quantum sought, and inviting settlement.
6. Issue summons. If no reasonable settlement is reached, issue summons in the High Court division with jurisdiction. Pleadings (declaratory claim, plea, replication) frame the issues for trial.
7. Discovery and pre-trial. Exchange evidence, settle expert reports in line with the rules of court, narrow the issues and hold a mandatory pre-trial conference.
8. Trial. The claimant leads expert evidence on breach, causation and quantum, and the matter is decided by the trial judge on the balance of probabilities.

Expert Evidence: The Centre of Proof

Because the standard of care is set by the profession itself, expert evidence from a specialist in the same field is the cornerstone of almost every medical-negligence claim. A properly framed expert report deals with each element of the claim:

• The factual basis on which the opinion is given (the clinical record).
• The accepted practice in the relevant specialty.
• The deviation from that practice on the part of the practitioner or institution.
• The causal link between that deviation and the harm alleged.

Multiple experts are commonly briefed in complex matters — both the treating practitioners who explain what happened clinically, and an independent expert retained for the action who expresses the opinion required for trial. The expert’s opinion is corroborated by the contemporaneous clinical record; documents come first, with the expert interpreting them.

The Res Ipsa Loquitur Doctrine in South African Law

The Latin maxim res ipsa loquitur — “the thing speaks for itself” — allows a court to draw the inference of negligence from the very nature of the injury, where:

• the instrumentality that caused the injury was under the control of the defendant, and
• the injury is of a kind that would not ordinarily occur in the absence of negligence.

The doctrine has been applied in South African medical-negligence cases, including Van Wyk v Lewis 1924 AD 438, where the inference of negligence was raised by the very fact of the harm. It does not remove the burden of proof — the claimant still bears the evidentiary burden — but it changes what a court may infer from the pleadings and the evidence before it. Res ipsa loquitur is most useful in clear-cut cases: a foreign object left in the body, wrong-side surgery, or an operation performed on the wrong patient.

Common Defences and How They Are Met

Defendants in medical-negligence matters rely on a small, well-known set of defences. Each is met with evidence-led argument.

Defence	Basis	How It Is Met
Inherent risk	The harm was a recognised complication of the procedure, properly disclosed in the consent process.	Show the risk was not properly disclosed, the consent was inadequate, or the practitioner failed to consider alternatives.
“Respectable minority”	A body of specialists would have acted similarly.	Defeats breach only if the minority view is logical, respectable and supported by the literature; challenge its evidentiary basis.
Causation defences	The harm would have occurred in any event (pre-existing condition, novus actus interveniens, lack of factual causation).	Evidence that the breach materially contributed to or accelerated the injury, with expert support.

Limitation, the Letter of Demand, and Where Pleadings Are Filed

Prescription is governed by the Prescription Act 68 of 1969. A medical-negligence claim prescribes after three years from the date the claimant became aware of the harm and its cause, subject to the outer limit of fifteen years from the act or omission, whichever expires first. The Rule 23 prescription-summons procedure is sometimes invoked to interrupt prescription where the claim is close to expiry; claimants who wait too long generally find a late claim difficult to revive.

The correct forum for an ordinary medical-negligence claim is the High Court division with jurisdiction over the place where the harm occurred or where the defendant practises — the Gauteng Division, the Western Cape Division, the KwaZulu-Natal Division, or another provincial division as the case may be. The Magistrate’s Court has limited jurisdictional ceilings and is generally the wrong forum for these claims.

Sending a properly framed letter of demand to the practitioner, the institution and the professional indemnity insurer is both a practical and a procedural expectation. It usually triggers the insurer’s investigation and is the precondition for meaningful settlement negotiation. Claimants should not issue summons before a demand has gone out.

What an Attorney Actually Does in These Matters

A medical-negligence claim is run by an attorney in coordination with admitted counsel in the relevant High Court division. The attorney’s role is to:

• marshal the medical record and instruct the independent experts;
• co-ordinate with counsel briefed in the division;
• manage Rule 23 prescription risk and the limitation timing;
• negotiate directly with the professional indemnity insurer on quantum;
• run the trial under counsel, coordinating pleadings, discovery and pre-trial processes.

Burger Huyser Attorneys runs these matters through its general litigation practice from the Randburg head office, drawing on directors and admitted attorneys across the firm’s Gauteng branches and co-ordinating with counsel in the relevant division — an early merits view from the litigation team can usually be obtained on the strength of the medical record and a draft expert report.

Frequently Asked Questions

Do I have to sue the doctor personally, or can I sue the hospital?

Both are usually joined. A hospital that employs the practitioner, or that is vicariously liable for an independent contractor in certain emergency settings, can be sued jointly with the individual practitioner. The claim addresses which defendant owed the duty and was in control of the relevant instrumentality.

I was harmed ten years ago — am I still within time to claim?

South African prescription law gives three years from the date the claimant knew or ought reasonably to have known the identity of the wrongdoer and the harm and its cause. There is an outer limit of fifteen years from the act or omission. The exact window depends on the facts; consult an attorney promptly, because a late claim is generally a hard one to revive.

Will the case go to trial, or is settlement common?

Most medical-negligence claims are resolved without trial. A properly framed letter of demand supported by an expert opinion regularly produces settlement discussions with the professional indemnity insurer. Where the quantum is significant, the matter is usually run through structured settlement negotiation; trial remains the forum in which disputes that cannot be settled are finally decided.

Can I rely on res ipsa loquitur instead of an expert?

In appropriate cases, the res ipsa loquitur inference lets the matter proceed without a full expert on breach where the injury itself is eloquent — for example a retained surgical instrument or wrong-site surgery. Expert evidence on causation and quantum is still typically required, because res ipsa loquitur addresses only the breach limb of the claim.

What damages can I claim?

General damages for pain, suffering and loss of amenities of life; special damages for past and future medical expenses; loss of past and future earning capacity; future medical and accommodation needs; and psychological damages. Quantum is calculated on the evidence of treating practitioners, accountants, actuaries and rehabilitation specialists.

Does my attorney get paid only if I win?

Fee arrangement depends on the attorney and the case. Some matters are run on a contingency (“no win, no fee”) basis where appropriate, but medical-negligence litigation typically involves a phased cost structure with a contingent element for trial work. Confirm the fee arrangement in writing before engagement.
