Westbrook Resources Ltd operated a manganese refining plant in Croatia and sought to improve efficiency by acquiring new processing equipment (jigs). Between August and November 2008, Westbrook and Metmar (later Traxys Africa Holdings (Pty) Ltd) concluded three partly oral and partly written agreements for the sale of three jigs at a total price of US$1.35 million. The written terms were contained in pro forma invoices, which included staged payment terms, with the final 30% payable on commissioning of the equipment in Croatia. A dispute arose as to whether Metmar was contractually obliged to commission the jigs or whether Westbrook (or its site manager, De Beer) bore that responsibility. Metmar delivered the jigs, but they were never properly commissioned and failed to operate effectively. Westbrook withheld the final payments and sued Metmar for damages arising from failure to commission. The trial was limited to separated issues concerning the obligation to commission. Both the trial court and the full court erred by failing to make substantive orders on the separated issues, prompting an appeal and cross-appeal to the Supreme Court of Appeal.
