I am curious what exactly has been served on De Ruyter. In other media it seems to be demands... basically an ultimatum, and they have given him 7 days to respond, or otherwise they will take him to court. In this instance, though there is willingness, they still need to show the intent and motive to take him to court.
At some point in time, evidence has to be provided, and The Daily Maverick did point to evidence being collected. There is a chance that De Ruyter might not respond in detail, I am sure that the ANC will receive a comprehensive report, stipulating evidence, in short time.
It is more a question as to who is behind the private investigations. Some media is privy, De Ruyter unleashed it into public, but who else? Are other Eskom board members also aware or involved, are the state involved… but what I can say, no such investigation will take place without one or more legal entities involved, because it will be plastered in legalities. I won't be surprised that this has all been deliberately put into motion to draw on a reaction. Whoever is behind this, is showing urgency where others didn't, so it could be civil rights movements, business or both.
I don't want to speculate too much, this will unravel. In the case evidence is presented, what will the ANC do with the evidence, how will the state react? What they will buy is time, and they will make sure that this time is process burdened.
Anyhow, The Daily Maverick can get to Part 2 already.
