Corruption Watch said the National Prosecuting Authority (NPA) told the organisation that it is reviewing its decision not to prosecute Tom Moyane. It said this development came after Corruption Watch asked for a certificate to be issued confirming that the NPA was not going ahead with the prosecution, as it wanted to pursue a private criminal prosecution. The suspended South African Reserve Service (SARS) commissioner is facing disciplinary charges. Corruption Watch, in a statement released on Monday, questioned why there appeared to be what it called "an apparent reluctance" on the part of the NPA to prosecute Moyane.

Earlier this month, the Presidency announced that it had served Moyane with disciplinary charges.

"It has damaged the integrity and credibility of SARS, a critical institution in South Africa's success, and Moyane cannot be allowed to escape with disciplinary sanctions alone," he said. "We will continue to demand that the NPA mount a prosecution, failing which we will do so ourselves."
