Cape Town - Advocate David Unterhalter SC was robbed at gunpoint while on his way to the South Gauteng High Court on Thursday morning."He is fine. He is okay. I've spoken to him," his secretary Tracy Nyschens told News24 in confirming the attack."He was stuck in the usual Johannesburg traffic and was a sitting target. It was a robbery at gunpoint."She could not say where it happened but said it was close to the court building.His cellphone and watch were taken.Unterhalter, 59, who was an acting judge for the urgent court roll in the high court this week, had already resumed his duties.Nyschens said she could not comment on whether the incident was isolated or connected to his cases.Gauteng police did not immediately respond to questions on if they were investigating and whether any suspects were apprehended.Unterhalter received his silk as an advocate in 2001.He most recently represented the SA Reserve Bank in an application to have the Public Protector's remedial action to change its constitutional mandate set aside.The application in the North Gauteng High Court was successful and the remedial action was set aside last week.
