The plaintiff bank, registered in Botswana, advanced loans to the first defendant totaling US$500,000 (US$425,000 on 14 September 2009 and US$75,000 bridging finance on 30 November 2009) to finance chrome production for export to China. The second defendant bound itself as surety and co-principal debtor, hypothecating its property (Stand 17 Winchedon Township). The third and fourth defendants executed deeds of guarantee as guarantors and co-principal debtors. On 31 January 2010, a rollover facility was granted extending repayment to 31 January 2011. The first defendant failed to perform, and the plaintiff claimed US$777,380.05 being capital and interest. The first defendant was placed under judicial management on 12 September 2012. The defendants alleged supervening impossibility due to a government ban on chrome exports imposed in April 2011, claiming they were only liable for capital.
