The applicant and first respondent entered into an oral agreement on 3 October 2019 whereby the first respondent was to purchase and supply 516 metric tonnes of fertiliser for the applicant within 30 days of payment. The applicant paid the full purchase price of US$321,726.00 into an account in South Africa, secured by a loan from its bankers. The first respondent only supplied 169.950 metric tonnes, leaving a balance of 346.050 metric tonnes outstanding. The applicant terminated the contract and sought a refund. The second and third respondents allegedly bound themselves as sureties, and the fourth and fifth respondents offered their property (stand number 997 Glenlorne) as security. The applicant served a notice of demand for US$211,314.47 (refund for undelivered fertiliser, interest, and penalties). When the respondents failed to pay, the applicant issued summons and subsequently applied for summary judgment against all respondents. The respondents opposed the application, claiming supervening impossibility due to Covid-19 lockdown regulations and challenging the joinder of the second to fifth respondents as sureties.
