JOHANNESBURG - Duduzane Zuma's case has been postponed to Thursday.
He faces one count of culpable homicide and one count of negligent and reckless driving.
Zuma's lawyers argue that the state has failed to prove that Zuma was reckless and negligent for causing the death of a taxi passenger.
In February 2014, Zuma’s Porsche slammed into a minibus taxi on the M1 highway resulting in two women losing their lives.
