On 17 February 2005, Innovent (appellant), a company that finances the acquisition and leasing of equipment, concluded a Master Rental Agreement with Transnet (respondent). Under this agreement, Innovent would acquire equipment according to Transnet's specifications and lease it to Transnet. The agreement was subsequently revised and five rental schedules were concluded for additional equipment. All agreements came to an end. Some equipment was returned and compensation was agreed for equipment not returned. The dispute concerned the condition in which the returned equipment was received. Innovent contended that the equipment had not been decommissioned in accordance with the manufacturer's specifications and was not accompanied by appropriate certificates as required by clause 11.2 of the Master Rental Agreement. It was common cause that the original manufacturer had not prescribed any special procedures for decommissioning the equipment and accordingly nothing had been done in this regard when equipment was returned. The trial court (Keightley J) upheld Innovent's claim. The full court (Nicholls J, Moshidi J and Coppin J concurring) allowed Transnet's appeal and substituted an order of absolution from the instance.
