The High Court in Pretoria ordered that Hawks boss Berning Ntlemeza should be dismissed immediately while he attempts to appeal the matter.
Last month the court set aside Ntlemeza's appointment by then Police Minister Nathi Nhleko in September 2015.
Nhleko gave Ntlemeza a permanent post despite Judge Elias Matojane's ruling that Ntlemeza "lacks integrity and honour".
Institute for Security Studies head of crime and justice programme, Gareth Newham, says Ntlemeza "wreaked a lot of damage" when he was at the Hawks.
Van Dalsen says the challenge now is to make sure that the next Hawks head is someone who will do the job well, not propelled into the position.
He says the head should chosen in the similar way that the Public Protector was appointed.
