APP stands for Additional Public Prosecutor. It is a government law officer appointed to prosecute criminal cases on behalf of the state — assisting the Public Prosecutor (PP) in conducting criminal trials before Sessions Courts, High Courts, and other criminal courts.
The APP plays a frontline role in India’s criminal justice system. From presenting the state’s case in sessions trials to opposing bail applications and arguing appeals, the APP is the legal representative of the state in criminal proceedings. Their work directly impacts whether justice is delivered to victims of crime.
Legal Basis — Section 24, CrPC
Section 24 of the Code of Criminal Procedure, 1973 (now equivalent provisions in BNSS, 2023) governs the appointment of Public Prosecutors and Additional Public Prosecutors:
- The State Government appoints a Public Prosecutor and may appoint one or more Additional Public Prosecutors for the High Court
- For every district, the State Government appoints a Public Prosecutor, and may appoint Additional Public Prosecutors for Sessions Courts
- The APP for Sessions Court must be an advocate of at least 7 years’ standing
The provision ensures that criminal prosecution is handled by legally qualified professionals — not administrative officers — protecting the fairness of trials.
Role and Functions of an APP
Trial Advocacy The APP appears in Sessions Court trials for serious offences — murder, robbery, rape, dacoity, organised crime. They examine prosecution witnesses, cross-examine defence witnesses, and argue on framing of charges and final arguments for conviction or sentencing.
Bail Opposition When accused persons seek bail in serious offences, the APP appears to oppose bail — presenting reasons why bail should be denied in the interests of justice, victim safety, and investigation integrity.
Appeals When accused are acquitted by trial courts, the APP advises the Director of Prosecution on whether to appeal. If the government decides to appeal, the APP (or a senior PP) argues the appeal before the High Court.
Witness Management The APP coordinates with police to ensure prosecution witnesses are available on trial dates — one of the most practically challenging aspects of the role given the difficulty of witness attendance in Indian courts.
Case Preparation Working with the investigating police to review charge sheets, identify evidentiary strengths and weaknesses, and prepare the prosecution strategy before the trial commences.
APP in High Court — “Ld. APP”
In High Court proceedings, the state’s representative in criminal matters is often referred to as the “Ld. APP” (Learned Additional Public Prosecutor). Court orders regularly reference the “Ld. APP” appearing for the State — particularly in bail applications, appeals, and criminal writ petitions.
The High Court APP handles:
- Criminal appeals against acquittals or sentence enhancements
- Bail applications before the High Court
- Criminal writ petitions (challenging lower court orders)
- References and revision applications
