George Stewart Muller and Others v Botswana Development Corporation Limited

The respondent (Botswana Development Corporation Limited) instituted action against three appellants for payment of P1,500,000.00 (Botswana Pula) or Rand equivalent, plus interest and costs. The claims arose from separate deeds of suretyship whereby each appellant bound themselves as sureties and co-principal debtors with Trans Africa Plastics (Pty) Ltd (the principal debtor), a company of which they were directors. The principal debtor's indebtedness arose from a loan agreement entered into at Gaborone, Botswana, whereby the respondent lent P1,500,000.00 to the principal debtor. At the time of institution of action, the debt including interest totaled P1,677,087.34. The appellants filed notice of intention to defend, and when the respondent applied for summary judgment, they opposed on the basis that the principal debtor had a bona fide counterclaim against the respondent which it intended to institute in proceedings already pending in the High Court of Botswana. The alleged counterclaim arose from: (1) delays in advances and provision of working capital finance only against suppliers' invoices, allegedly preventing expenditure on capital equipment and causing loss of profit; and (2) an ex parte interdict obtained by the respondent from the High Court of Botswana allegedly on false allegations, which prevented the principal debtor from carrying on business and caused it to cease trading. The appellants sought to stay the action pending determination of the Botswana proceedings.

• Whether a surety is entitled to rely on an unliquidated counterclaim to be instituted by the principal debtor against the creditor to resist summary judgment
• Whether the opposing affidavit disclosed material facts sufficient to establish a bona fide defence in terms of Uniform Rule 32(3)(b)
• Whether Uniform Rule 22(4) regarding counterclaims that may extinguish a plaintiff's claim is available to a surety relying on a counterclaim of the principal debtor
• Whether an illiquid claim for damages can constitute a valid defence to prevent summary judgment

The appeal was dismissed with costs. The summary judgment granted by the court a quo (Griesel J) was upheld.

A surety opposing summary judgment on the basis of an alleged unliquidated counterclaim by the principal debtor must comply with Uniform Rule 32(3)(b) by disclosing fully in the opposing affidavit the nature and grounds of the defence and the material facts relied upon. Bare, unsubstantiated allegations without specification of the nature of any breach, unreasonableness of conduct, or causal connection between alleged wrongful acts and damages claimed do not constitute material facts sufficient to establish a bona fide defence. While an illiquid counterclaim for damages cannot effect set-off until liquidated by judgment, the practice of allowing such counterclaims to be pleaded in anticipation of future set-off (under Rule 22(4)) does not relieve a defendant of the obligation to properly substantiate the factual basis for such counterclaim when opposing summary judgment.

Mpati JA made important obiter observations regarding the availability of Uniform Rule 22(4) to sureties. He noted conflicting precedents: Rose-Innes J in Standard Bank v SA Fire Equipment (1984) held that Rule 22(4) is available to sureties relying on counterclaims of the principal debtor, reasoning it would be anomalous if the Rule precluded as a matter of pleading a defence that exists as a matter of law. Erasmus J in J R & M Moffett v Kolbe (1974) held the contrary view based on a narrower interpretation of the Rule's wording. Mpati JA stated that Rose-Innes J's view was "the more attractive" and suggested there was no reason to differentiate between cases where principal debtor and surety are sued together versus separately in different fora. However, he expressly refrained from making a definitive ruling on this issue, leaving it open for future determination. The Court also noted obiter that the alleged loss of profit appeared to be special or consequential loss, ordinarily regarded as too remote to be recoverable unless the parties actually or presumptively contemplated such loss as a probable result of breach, but did not need to decide this point.

This case is significant in South African law for clarifying the requirements for sureties opposing summary judgment based on alleged counterclaims of the principal debtor. It reinforces that while sureties may potentially rely on defences available to the principal debtor (including anticipated set-off following judgment on a counterclaim), they must still comply strictly with the requirements of Uniform Rule 32(3)(b) by disclosing fully the nature and grounds of the defence and the material facts relied upon. The judgment demonstrates that bare, unsubstantiated allegations without specification of breach or material facts will not suffice to resist summary judgment. The case also highlights the unresolved tension in South African law regarding the interpretation of Uniform Rule 22(4) and whether it extends to sureties relying on counterclaims of principal debtors, though the Court deliberately left this issue open for future determination. It emphasizes the procedural rigor required in opposing summary judgment applications.
