The dispute arose from a 1985 tri-partite licensing and sub-licensing agreement relating to the manufacture and sale of diaphragm valves, under which Insamcor (Pty) Ltd was obliged to pay royalties to Dorbyl Light & General Engineering (Pty) Ltd (DLG). DLG had been deregistered in 1996 under s 73(5) of the Companies Act 61 of 1973 after its business was transferred to its parent company, Dorbyl Ltd. Despite this, DLG later sought and obtained a restoration order under s 73(6) without notice to Insamcor, and thereafter instituted motion proceedings claiming unpaid royalties and an interdict against Insamcor. Insamcor discovered the prior deregistration shortly before the royalties matter was heard and launched a separate application to set aside the restoration order on the basis of non-joinder, material non-disclosure, and lack of competence of part of the order.
