Lephat Zulu v National Railways of Zimbabwe

Plaintiff Lephat Zulu was employed by the National Railways of Zimbabwe (NRZ), a statutory body established under the Railways Act [Chapter 13:09]. On 3 May 1983, he was injured in a work-related accident and was assessed to have suffered 15% disability. The National Social Security Authority (NASSA) approved a compensation award of $7,374.50 based on this disability assessment. NRZ alleged it paid plaintiff the sum of $7,374.50 on 15 January 2002 via cheque number 113396. Plaintiff denied receiving any payment. He received a disability assessment letter on 15 August 2001 (Exhibit A1) which he submitted to NRZ's senior medical doctor. He obtained another assessment letter on 14 May 2015 (Exhibit A2) and submitted it to NRZ. In 2016, when he enquired about payment, NRZ informed him he had been paid. He disputed this and sued for the compensation amount in 2018. NRZ raised a special plea regarding prescription and currency (as the cause of action arose when Zimbabwean dollars were legal tender), which was dismissed in an earlier judgment (HB 70/20). The matter proceeded to trial on whether payment had been made.

• Whether the defendant had discharged its onus of proving on a balance of probabilities that it paid the plaintiff the compensation sum of $7,374.50
• Which party bears the burden of proof when a defendant alleges payment as a defense to a debt claim
• The applicable standard of proof in civil matters where circumstantial evidence is relied upon
• Whether the plaintiff's long period of inactivity (2001-2015) supported an inference that payment had been made

The plaintiff's claim was dismissed with costs of suit.

In a claim for recovery of a debt, where the defendant admits the debt was owed but pleads payment as a defense, the defendant bears the burden of proving on a balance of probabilities that payment was made. In civil proceedings based on circumstantial evidence, the court must select the most plausible conclusion by balancing probabilities - the inference sought need not be the only reasonable inference, but must be the most probable inference that can be drawn from the evidence and facts. A court is entitled to draw adverse inferences from a party's failure to produce relevant documentary evidence within their possession or control. Prolonged unexplained inactivity or delay by a claimant in pursuing a claim may support an inference that the debt has been satisfied.

The court observed that the plaintiff's claim that he did not know he was entitled to compensation after obtaining a specialist disability assessment was inherently implausible and untruthful, given that he was employed as a clerk and had actively pursued obtaining the medical assessment. The court noted approvingly that the defendant's accounting systems included multiple checks and controls (payment requisition office, payment processing office, and reconciliation office) that would detect non-payment. The court commented that the defendant's explanation for inability to produce banking records due to a 10-year retention policy was credible and reasonable. The court expressed the view that where bank statements for a relevant period could be retrieved (as evidenced by the police docket containing earlier statements), the failure to produce statements for the specific period in question warranted scrutiny.

This case is significant in Zimbabwean civil procedure and evidence law for several reasons: (1) It clarifies the allocation of the burden of proof where a defendant admits a debt but pleads payment as a defense - the defendant bears the onus of proving payment; (2) It demonstrates the application of the balance of probabilities standard in civil cases relying on circumstantial evidence, affirming that the court must select the most plausible inference even if it is not the only reasonable one; (3) It illustrates how courts assess credibility and draw inferences from conduct, particularly prolonged inactivity or delay in pursuing claims; (4) It shows the importance of documentary evidence and the adverse inferences that may be drawn from failure to produce relevant documents within a party's possession or control; (5) It addresses practical evidential issues arising from the passage of time and destruction of records according to retention policies; (6) The case demonstrates judicial reasoning in evaluating competing versions and assessing probabilities in the absence of direct evidence of payment.
