Judgment is expected on Friday in the trial of Duduzane Zuma, who faces a charge of culpable homicide, in the Randburg Magistrates' Court.
The charge relates to a 2014 car crash that resulted in the death of Phumzile Dube. The Zimbabwean woman died after Zuma’s Porsche crashed into a minibus taxi on the M1 highway in Johannesburg.
The 35-year-old accused is the son of former president Jacob Zuma, who often accompanied his son during the trial.
The National Prosecuting Authority (NPA) initially decided not to prosecute Zuma in connection with the accident.
AfriForum and Advocate Gerrie Nel's Private Prosecution Unit took on the matter and demanded justice on behalf of the Dube family.
During closing arguments, the state emphasised the witness testimony of passengers and the taxi driver that the accused drove past them in a way that is not considered normal and that he should have foreseen that an accident could have happened.
