Constantine Mandengu and Miriam Tawuya Mandengu v Peter Mandava and Premier Service Medical Investment (Pvt) Ltd t/a Premier Service Westend Hospital

The plaintiffs issued summons against the defendants for damages totaling USD 1,775,410.48 arising from alleged gross negligence and lack of diligence, skill, and care. The second plaintiff suffered respiratory failure/emergency allegedly due to residual anesthesia administered by the first defendant (an anesthetist) following a surgical procedure on or about 18 March 2019. The respiratory failure allegedly resulted in hypoxia or hypoxemia, leaving the second plaintiff brain dead, vegetative, and disabled for life. The first defendant was engaged by Dr Israel Dube, the second defendant's General Surgeon. The plaintiffs alleged the cause of action arose on 26 October 2022. The summons was issued on 30 July 2024. The first defendant filed an exception and special plea of prescription. The second defendant filed a special plea but did not participate in these proceedings.

• Whether the plaintiffs' pleadings were vague and embarrassing due to conflation between claims in contract and delict
• Whether the plaintiffs' pleadings disclosed a cause of action
• Whether the plaintiffs' claim had prescribed
• When the cause of action arose for purposes of prescription
• What is the proper order when an exception succeeds

1. The exception based on vague and embarrassing pleadings (conflation of contract and delict) was upheld. 2. The special plea of prescription was dismissed. 3. No order as to costs.

1. A plaintiff cannot plead both contract and delict as causes of action unless such pleadings are in the alternative. Where a plaintiff simultaneously pleads both breach of contractual duty and delictual negligence for the same claim without pleading in the alternative, the pleadings are vague and embarrassing. 2. An exception based on failure to disclose a cause of action requires that the pleadings fail to state facts necessary to be proved, not that they lack evidentiary detail. A cause of action comprises every fact necessary to be proved, not every piece of evidence needed to prove each fact (applying McKenzie v Farmers' Cooperative Meat Industries Ltd). 3. In a special plea of prescription, the defendant bears the onus of proving that the claim has prescribed. Where there is a factual dispute as to when the cause of action arose, the defendant must adduce evidence to discharge this evidential burden (applying Brooker v Mudhanda). 4. When an exception has merit, the correct order is to uphold the exception, not to dismiss the claim (applying Group Five Building Ltd v Government of the Republic of South Africa).

The court made several non-binding observations: (1) That a party who has filed a plea of prescription and not pleaded over has a right to file further pleadings within the time allowed by the rules of court upon dismissal of the special plea. (2) The court noted that civil litigation is litigant-driven, emphasizing the importance of parties discharging their respective burdens. (3) The court reiterated the charitable test applicable to exceptions, citing Southernpoort Developments (Pty) Ltd v Transnet LTD, noting that pleadings should not be examined with 'a magnifying glass of too high power' and that pleadings must be read as a whole. (4) The court observed that even if averments are lacking in detail, the remedy cannot be an exception, suggesting that other remedies (such as requests for further particulars) may be more appropriate. (5) The court noted the distinction between the primary purposes of contractual and delictual remedies: contractual remedies enforce agreements or compensate for non-fulfillment of terms, while delictual claims have different objectives.

This case provides important guidance on several procedural matters in Zimbabwean civil litigation: (1) It reinforces the principle that plaintiffs cannot simultaneously plead claims in both contract and delict without pleading them in the alternative, following South African jurisprudence such as Gerber v Naude. (2) It clarifies the distinction between exceptions based on lack of cause of action versus vagueness and embarrassment. (3) It affirms that in a special plea of prescription, the defendant bears the onus of proving when prescription commenced and must adduce evidence to discharge this burden, particularly where there is a factual dispute. (4) It clarifies that when an exception is upheld, the proper order is to uphold the exception, not to dismiss the claim. (5) The case is significant in the context of medical negligence litigation, addressing the relationship between contractual duties of medical practitioners and delictual duties of care.
