Eskom wants Gupta-linked Trillian and global consultancy firm McKinsey to pay back the R1.6 billion in consulting fees from an unlawful contract.
The power utility has warned that if the money is not reimbursed by Tuesday, McKinsey and Trillian may face legal charges.
The charges "against implicated parties" may include theft‚ fraud and corruption, reports Financial Mail's Sikonathi Mantshantsha.
He explains that Eskom wants the money returned after receiving legal advice from several law firms, including Bowmans.
It is questionable whether [Trillian and McKinsey] did any work to earn the R1.6 billion fees.— Sikonathi Mantshantsha, deputy editor at the Financial Mail
Eskom say they will approach a court if they fail to reach an agreement or if these guys [Trillian and McKinsey] fail to do as instructed.— Sikonathi Mantshantsha, deputy editor at the Financial Mail
Mantshantsha says the replacement of Eskom's Head of Legal last week may also affect how the utility proceeds.
He doubts that Trillian and McKinsey will go down without a fight.
Meanwhile, the Eskom board apparently held an unscheduled meeting on Monday morning.
