Engen Petroleum Limited and Windsharp Trading (Pty) Ltd concluded an Engen Diesel Club agreement under which Windsharp became indebted to Engen for more than R5.5 million. As security, Windsharp executed two deeds of cession in favour of Engen, the latter in June 2014 expressly including all reversionary rights in the ceded debts. Windsharp was provisionally liquidated in November 2014. Engen notified Flotank Transport (Pty) Ltd, a debtor of Windsharp, of the cession and demanded payment directly to Engen. Despite notice, Flotank paid nine amounts to Windsharp after liquidation. Engen sought payment of those amounts from Flotank. The High Court held the cession was a pledge in securitatem debiti, entitling Windsharp’s liquidators rather than Engen to claim the debts. Engen appealed.
