Deputy chief justice Raymond Zondo, who is chairing the commission, said Jonas’s application should have been served to Zuma’s legal team.
"I regret that there was this inconvenience caused. I postponed the hearing of Jonas to November 26. I have suggested that the three legal teams should have a conversation with regard to what would happen," Zondo said.
There was another issue around the appearance of Mzwanele Manyi on Wednesday.
Manyi was expected to give evidence before the commission on November 23, but had received a notice that there was an opening on Wednesday. The notice is believed to have been issued erroneously.
Manyi will testify on November 23.
Manyi’s company Lodidox bought Gupta-owned news channel ANN7 for R300m and The New Age newspaper for R150m but closed them both down shortly afterwards.
The former government spokesperson has been an outspoken supporter of former president Jacob Zuma.
He tweeted that former minister Barbara Hogan had lied to the commission on Tuesday.
