Courts increasingly monitor criminal investigations through PILs. Discuss the merits and the risks of judicial overreach in such court-monitored probes.

Court-monitored probes rest on continuing mandamus: the court keeps a PIL pending and asks the investigating agency for periodic status reports. The Supreme Court developed this tool in Vineet Narain (1997) [2]. A recent example is the Madras High Court's Madurai Bench asking for a status report on the probe into faeces found in a school water tank at Manoor, Dindigul [1]. Court monitoring can fix a failing investigation, but courts should use it only in exceptional cases.

Merits

• It breaks inertia and outside influence. At Manoor, the tank was cleaned before officials were told, and the case was registered three days late. The petitioner alleged that influential persons interfered [1].
• It shields agencies from the executive. In Vineet Narain, the Court supervised CBI inquiries that involved powerful people [2].
• It enforces legal duties. An FIR is mandatory when a cognizable offence is disclosed (Lalita Kumari, 2013) [3]. Court monitoring makes police explain any delay.
• It protects vulnerable groups. About 150 children's right to safe water under Article 21 was at stake [1].
• Courts can act in steps. A status report is the mildest tool. The Bench has not yet granted the independent team the petitioner asked for [1].

Risks of overreach

• Separation of powers. Investigation is an executive function under statute. BNSS Section 173(3) now allows a preliminary enquiry for offences punishable with 3 to under 7 years [4]. Court pressure may override this lawful discretion.
• Prejudice to the accused. Remarks by the monitoring court can influence the trial court and feed media trials.
• No accountability for outcomes. Courts supervise the probe but cannot be held answerable if it goes wrong.
• Docket burden and misuse. Monitoring can go on indefinitely, and PILs can be filed for publicity or political ends.
• Symptoms, not causes. Supervising one case at a time does not fix structural weaknesses in policing.

Way forward

• Intervene only when there is prima facie inaction or bias.
• Set deadlines for status reports and avoid comments on the merits.
• Escalate step by step, for example transferring the case to an SIT only if progress stalls.

Court-monitored probes are a valuable safety valve against agencies that fail to act. Their legitimacy depends on judicial restraint. Used sparingly, with time limits and in support of police accountability reforms, they uphold the rule of law and Article 21 without taking over the executive's role.
