Gerrie Nel from lobby group, AfriForum said he will privately prosecute Duduzane Zuma on a charge of culpable homicide.
According to Nel, the court papers were filed on Tuesday morning.
Even after an inquest found Zuma’s conduct led to the crash, the National Prosecuting Authority (NPA) declined to prosecute in August 2015.
"Dube’s family deserves that justice is served and that the case is not treated differently as a result of who the perpetrator is," AfriForum said in a tweet.
