In the latest round of the legal battle between “please call me” inventor Nkosana Makate and Vodacom, the telecommunications giant has been ordered to hand over financial records related to the service, as well as value-added service contracts it had with other service providers, to assist in determining the value of the ground-breaking idea.

The high court in Pretoria said on Monday that Vodacom has 21 days to hand over the records so that it will be able to determine how much is owed to Makate.

Vodacom is ordered to pay the costs of the action, including costs of two counsel, if applicable, as well as the costs of an expert

The figure reflects a 5% share of an estimated R205-billion in revenue that Makate believes was generated from “please call me”, including interest calculated over an 18-year period in the 20-year battle.

Makate approached the courts seeking that Vodacom CEO Shameel Joosub disclose the documents the group relied on to conclude that R47-million was the amount due to him for the idea.

Judge Jody Kollapen handed down a judgment that orders Vodacom to commence negotiations in good faith to determine a reasonable compensation payable to Makate.
