Paroan Trucking (Pvt) Ltd t/a Petrol-Oil Zim v Mossrich International Trading (Pvt) Ltd and Harwich Trading t/a Bindura Service Station and Tanatsiwa Huruva

In August 2010, the plaintiff entered into an agreement with the first defendant (represented by the second and third defendants) to obtain a confirmed letter of credit worth US$3,000,000 to enable the plaintiff to secure fuel. The parties agreed that defendants would receive 10% of the face value (US$300,000) to facilitate acquisition of the letter of credit from international financiers. The plaintiff paid US$300,000 in three instalments (US$150,000 on 4 August 2010, US$110,000 on 14 August 2010, and US$40,000 on 18 August 2010) into the second defendant's bank account. The promised letter of credit did not materialise or was unconfirmed and unacceptable to suppliers. The plaintiff demanded a refund, and the third defendant provided three written acknowledgements of debt dated 10 June 2011, 28 July 2011, and 9 December 2011, undertaking to repay the US$300,000. When payment was not made, the plaintiff instituted proceedings. At trial, the special plea regarding lack of jurisdiction over the first defendant (a peregrinus) was upheld. The second and third defendants defended on the basis that they did not stand as surety and co-principal debtors, and that the third defendant signed the acknowledgements under duress.

• Did the second and third defendants stand as surety and co-principal debtors with the first defendant for repayment of US$300,000?
• Did the third defendant sign the acknowledgements of debt under duress or undue influence?
• Whether the defendants performed their contractual obligations by providing valid letters of credit?
• Whether threats of criminal prosecution or civil litigation constitute unlawful duress sufficient to vitiate consent to a contract?

1. The second and third defendants were ordered to pay the plaintiff US$300,000 jointly and severally, the one paying the other to be absolved. 2. Interest at the rate of 5% per annum on US$300,000 calculated from 10 June 2011 to the date of final payment. 3. Costs of suit jointly and severally, the one paying the other to be absolved.

A threat of lawful criminal prosecution or civil litigation does not constitute unlawful duress sufficient to vitiate consent to a contract or acknowledgement of debt. For duress to succeed, three elements must be established: (1) the fear must be such as would overcome the resistance of a person of ordinary firmness, taking into account the characteristics of the victim; (2) the threat must be of imminent or inevitable evil that cannot be averted otherwise than by agreeing to the contract; and (3) the threat must be unlawful or contra bonos mores. Threats to pursue lawful legal remedies do not satisfy the requirement of unlawfulness. A sophisticated business person with legal knowledge who understands contractual principles (caveat subscriptor) and who signs multiple acknowledgements of debt over several months, after civil proceedings have already been instituted, cannot credibly claim duress. The principle of undue influence requires proof that: (a) the other party exercised influence; (b) this influence weakened the victim's powers of resistance and made his will pliable; and (c) the other party exercised this influence in an unscrupulous manner to induce consent to a detrimental transaction.

The court observed that the third defendant was prepared to engage in a high level of prevarication and gave false evidence regarding performance of the contract. The court noted that if performance had actually occurred, a sophisticated businessman would have produced proof long before trial. The court also commented that defences raised belatedly at the eleventh hour, such as illegality, are unfair and prejudicial to the opposing party, particularly when they could have allowed the plaintiff to rely on alternative remedies such as unjust enrichment or the in pari delicto rule. The court expressed the view that it would be unreasonable to expect that plaintiff's representatives would "perpetually dish out empty threats ad infinitum" if the third defendant's version were true, describing such conduct as a "pretty dumb thing to do." The court observed that the plaintiff's witnesses were credible and "not dumb at all."

This case is significant in Zimbabwean contract law for its clarification of the doctrine of duress and undue influence, particularly in commercial contexts. The judgment reinforces that threats of lawful criminal prosecution or civil litigation do not constitute unlawful duress sufficient to vitiate consent to a contract, especially acknowledgements of debt. The case emphasizes that the test for duress is objective (what would overcome a person of ordinary firmness) but takes into account the subjective characteristics of the victim. Importantly, it establishes that sophisticated business persons with legal knowledge will be held to higher standards when claiming duress - their commercial experience and understanding of legal principles (such as caveat subscriptor) will be considered when assessing whether their will was genuinely overborne. The case also demonstrates the court's intolerance for late-raised defences not pleaded at the pre-trial stage, and reinforces the principle that multiple acknowledgements of debt over an extended period are inconsistent with a claim of duress.
