Prosecution is part and parcel of the Judiciary. It is an interface between the Police and the Court. Otherwise, the Criminal Laws restricts Police to address directly to the Court [only if required to be, they are allowed to address for limited purpose, just to an extent of clarifications] and it has no legal powers to do so, hence the Prosecution acts between the Courts and the State represented Police.

The Directorate of Prosecution appoints Prosecutors to the Magistrate and Sessions Courts and the State Government too appoints / nominate Prosecutors directly in some Courts.
