In January 2009, Engen and Windsharp entered into an Engen Diesel Club (EDC) agreement. By June 2014, Windsharp owed Engen over R5.5 million. As security for the debt, Engen and Windsharp concluded two deeds of cession: the first in April 2012 and a second in June 2014. The 2014 cession replaced the 2012 cession and included a clause expressly ceding "any and all reversionary rights the Cedent might otherwise have had in and to the claim hereby ceded."
On 5 November 2014, a provisional order of liquidation was obtained against Windsharp at Engen's instance, which was made final in January 2015. On 9 December 2014, Engen notified Flotank of the 2014 cession and demanded that Flotank make payments directly to Engen. Flotank requested a copy of the cession by 12 December 2014 at 13h00, which Engen failed to provide. Between 12 December 2014 and 30 January 2015, Flotank made nine payments to Windsharp totaling over R2.2 million. In May 2017, Engen applied to the high court for an order that Flotank pay these amounts to Engen. The high court dismissed the application, finding that the cession was a pledge and that on liquidation the ceded debts reverted to Windsharp's liquidators.
