The IPID derives its mandate from the Independent Police Investigative Directorate Act (1 of 2011) that was enacted and came into effect on 1 April 2012 to enable the IPID to shift from a complaints driven institution to one that prioritizes the investigation of serious and priority crimes allegedly committed by the South Police Service (SAPS) and the Municipal Police Services (MPS). It also has a greater focus on systemic corruption. The Act also places a stringent obligation on SAPS and the MPS for reporting on matters that must be investigated by the Directorate and the implementation of disciplinary recommendations. The Directorate's overarching goal is to contribute towards ensuring a police service that trusted by the community and operates in line with the spirit of the Constitution.
