On 24 July 2009, ZB Bank Limited (the defendant) granted a revolving credit facility of up to $250,000 to Oxford Agro Chemicals (Pvt) Ltd (the company). Robert Morley (the plaintiff), a director and shareholder of the company, signed a guarantee on 5 August 2009 and passed a surety bond and mortgage bond over his Mt Pleasant property on 9 October 2009, securing the company's obligations. The total capital advanced was $223,903.15. The company defaulted on repayments. The defendant obtained judgment against the company. Following sales of assets and cash payments, $214,525 was paid to the defendant, but a balance remained outstanding. The plaintiff claimed he should be discharged from liability as surety on the basis that: (1) his liability under the surety bond was limited to $102,000; (2) the defendant had been paid more than this amount; and (3) the defendant varied the loan agreement by granting the company time to pay without his consent, which prejudiced him.
1. The plaintiff's claim was dismissed. 2. The defendant's counterclaim succeeded. 3. The plaintiff was ordered to pay: (a) US$223,903.15 being capital; (b) US$147,153.00 being interest; (c) US$32,101.09 being bank charges; (d) Interest on the capital sum at plaintiff's overdraft rate from 1 May 2014 to date of payment; (e) Costs on a legal practitioner and client scale and collection commission.
1. A surety bond executed after a guarantee does not automatically supersede or replace the guarantee where both documents are expressed as continuing covering security "without prejudice" to other securities. Both remain enforceable as cumulative security. 2. A continuing covering surety bond is not limited to the stated bond amount where clause 5(i) or similar provisions expressly extend coverage to "all and any sum or sums of money which shall now or may in future be owing...from whatsoever cause arising" including costs and charges. 3. A surety seeking discharge based on the creditor granting time to pay the principal debtor after default must prove: (a) the extension was granted without the surety's knowledge or consent, AND (b) the surety was actually prejudiced by the extension. Participation in requesting the extension defeats this defense. 4. Guarantees and surety bonds covering debts "howsoever arising" or "from whatsoever cause" extend to judgment debts obtained against the principal debtor. The creditor may enforce such judgments against the surety even though the surety is not a named judgment debtor. 5. Payment exceeding the original capital amount does not discharge the debt or suretyship where interest, charges and other amounts remain owing under the facility terms.
The court made observations about the credibility of witnesses, noting that the plaintiff did not impress as a truthful witness, evaded questions in cross-examination, and attempted to distance himself from knowledge of the debt despite being a director who mortgaged his home as security. The court also observed that it is "inconceivable that having mortgaged his house, he would not be interested in what was going on with the facility." The court noted that the variation defense was an "afterthought" not properly pleaded, though it analyzed the merits in any event. The court also commented that the defense witness gave evidence well, was straightforward, and was not shaken under cross-examination. While these credibility findings influenced the factual determinations, they constitute observations on witness demeanor rather than binding legal principles.
This case is significant in Zimbabwean suretyship law as it clarifies several important principles: (1) Multiple security documents (guarantee and surety bond) can coexist as cumulative security without one superseding the other, particularly where expressed as "without prejudice" to other securities; (2) Continuing covering security clauses must be interpreted holistically, and specific monetary limits must be read in conjunction with broader liability clauses; (3) The requirements for discharge of a surety based on variation of the principal contract are strict - the surety must prove both lack of consent AND actual prejudice from the variation; (4) A surety who participates in requesting or negotiating extensions of time to pay cannot later claim the extension discharged the suretyship; (5) Broadly worded guarantees and surety bonds covering debts "howsoever arising" extend to judgment debts and are enforceable even where the surety is not named as a judgment debtor. The case reinforces the binding nature of commercial suretyships and the courts' reluctance to release sureties based on technical arguments where the underlying debt remains unpaid.
