He said Dangor would tell the inquiry that Dlamini did not heed his warning. Dlamini is appearing before an inquiry into her role in the social grants saga. She has maintained that she is not to blame for the debacle.
The inquiry is a directive of the Constitutional Court‚ which last year ordered the investigation as a prerequisite for a ruling on Dlamini's culpability.
The court had in 2014 declared that the 2012 contract Sassa signed with CPS for the payment of social grants was invalid because of tender irregularities.
The court suspended its order of invalidity on the premise that Sassa would find new contractors to pay grants from April 1 2017‚ or that it would make payments on its own.
The Black Sash Trust had approached the court in March last year after Sassa acknowledged it would not be able to pay millions of grants from April 1‚ despite promising the court in November 2015 it would do so.
