Could somebody remind me what IRBA did about the "Pikoli" matter?

Advocate Vusi Pikoli was the NPA boss who got fired for defying Mbeki and prosecuting SAPS Commissioner  Jackie Selebi.  He subsequently joined the fifth largest SA audit firm, the BEE company, SizweNtsalubaGobodo.  After SNG was informed that their auditing of Transnet was contingent on Pikoli not being part of that firm he was summarily fired.

Apart from this probably being corruption, auditors are meant to be independent, and any firm that takes instructions from its clients is about as independent as the ZANC caucus or Saxonwold Shebeen.

If IRBA did anything, they must have done so in secret as I do not recall it being in the media.
