Innovent Rental & Asset Management Solutions (Pty) Ltd, a financier of equipment leasing, concluded a Master Rental Agreement with Transnet SOC Ltd in 2005 under which Innovent acquired equipment specified by Transnet and leased it to Transnet under various rental schedules. All the agreements terminated by effluxion of time. Some equipment was returned, while compensation was agreed for equipment not returned. The dispute concerned the condition in which certain equipment was returned and whether, under clause 11.2 of the Master Rental Agreement, the equipment had to be ‘decommissioned’ in accordance with the original manufacturer’s specifications and accompanied by certificates. It was common cause that the original manufacturer had prescribed no decommissioning specifications and no such decommissioning had been undertaken.
