Frans Barrie SC, representing Koko, said his client was anxious to get the proceedings under way.
"This is the second time. The first time the matter was simply postponed.
"According to the prescripts of the Eskom disciplinary code, labour matters such as these need to be dealt with within a certain timeframe and we are long past that.
"We are very, very anxious for this matter to get under way," Barrie said.
Koko is accused of failing to declare a conflict of interest when he contributed to the awarding of about R1-billion in contracts to a company in which his stepdaughter was a shareholder.
