The CDDP's powers derive from section 9 of the DPP Act. In describing that section, the Prosecution Policy of the Commonwealth at 4.1 says:

This provision encapsulates in a statutory form one of the main purposes in establishing the DPP—that the decision whether and how a prosecution proceeds should be made by the DPP independently of those who were responsible for the investigation.

If someone acted as an investigator and later became the prosecutor in the same matter, would that contradict the Prosecution Policy of the Commonwealth?
