Supreme Court held that a Private Counsel of Victim cannot examine witnesses and make arguments instead of the Public Prosecutor or Assistant Public Prosecutor.

From Para 10

10. From a reading of these provisions, it is clear that a Public Prosecutor is entrusted with the responsibility of conducting the prosecution of a case.  That this is a crucial role is evident from conditions such as in Section 24(7), which stipulates a minimum legal experience of seven years for a person to be eligible to be a Public Prosecutor. It is further clear from a joint reading of Section 301 and the proviso to Section 24(8) that the two provisions are mutually complementary. There is no bar on the victim engaging a private counsel to assist the prosecution, subject to the permission of the Court.
