Cornerstone Logistics (Pty) Ltd (first appellant), a licensed clearing agent, contracted with Zacpak Cape Town Depot (Pty) Ltd (respondent), a licensed customs warehouse operator, for warehousing services. Preston Cheslin Aitken (second appellant) signed as surety and co-principal debtor. Between August 2017 and November 2018, Cornerstone instructed Zacpak to store various consignments of alcohol in its customs warehouse. The goods were released to Bridge Shipping for export to Mozambique but were impermissibly diverted for home consumption in South Africa. In December 2018, SARS demanded payment from Zacpak of R37,416,153.27 in duties, VAT and other charges, alleging that Zacpak failed to provide proof of export and that the CN2 forms (proof of export) were false and invalid. Zacpak sought to enforce indemnity and suretyship clauses against the appellants. The appellants disputed that they had instructed release of goods, claimed the indemnity did not apply where Zacpak was at fault, and argued the suretyship was limited to storage charges up to R30,000.
