1. The SIU funding model provided for its baseline grant from National Treasury. In addition to the grants from National Treasury, the service-level agreements that SIU entered into with state institutions that required investigation made provision for SIU to charge for the services rendered, thus raising additional revenue. A legal opinion was obtained in 2011 to the effect that the SIU Act did not specifically empower such a model and that the SIU as a creature of statute could not continue with that model. The Unit was able to invoice on a limited basis between September 2011 and June 2012. This challenge has since been overcome by amendments to the Act, which are now enacted.
