Group Five Construction (Pty) Ltd was appointed as the main contractor on a construction project known as Pearls of Umhlanga – Pearl Sky. Millenium Aluminium and Glass Services CC was appointed as a nominated subcontractor under a JBCC Series 2000 subcontract and was required to furnish a performance (construction) guarantee. Constantia Insurance Company Ltd issued a construction guarantee in favour of Group Five Construction. Millenium failed to pay a certified payment amount reflected in a payment certificate issued by Group Five Coastal (later trading as Group Five KZN), acting as agent for Group Five Construction. After written demands in terms of the guarantee were made and not complied with, Group Five Construction called up the guarantee. Constantia refused payment, leading to High Court proceedings where Constantia was ordered to pay under the guarantee and the appellants were ordered to indemnify Constantia. Millenium and the other appellants appealed to the Supreme Court of Appeal.
