Preliminary Inquiry before Registration of FIR (s.173(3) BNSS) — BNSS (Criminal Law II) Notes

Preliminary Inquiry before Registration of FIR (s.173(3) BNSS)

If registration of an FIR is mandatory for a cognizable offence, can the police ever pause to check first? Lalita Kumari (2014) said yes — in a narrow band of cases — and the BNSS has now written that pause into the statute as s.173(3).

For offences punishable with 3 years or more but less than 7 years, the officer in charge may, with the prior permission of a DSP-rank officer and having regard to the nature and gravity of the offence, conduct a preliminary inquiry within 14 days to ascertain whether a prima facie case exists — before registering the FIR.

Who. The officer in charge, with a superior’s permission.
When. Only for the 3-to-under-7-year band; not for grave offences (7 years and above), where registration is immediate.
How long. The inquiry must conclude in 14 days.
Purpose. To filter out frivolous or malicious complaints without blocking genuine ones — a codification of the Lalita Kumari exception (matrimonial, commercial and medical-negligence disputes were the examples the Supreme Court gave).

🧩 WORKED EXAMPLE — when a pause is allowed

Facts. A complaint alleges a cognizable offence punishable with 5 years.

Rule. Section 173(3) allows a 14-day preliminary inquiry (with a DSP’s permission) for the 3-to-under-7-year band to check for a prima facie case.

Apply. The officer may inquire briefly before registering; had the offence carried 10 years, he would have to register the FIR at once.

Conclusion. A short, permitted pause is lawful here; it would not be for a grave offence.

Section 173(3) BNSS: “on receipt of information relating to the commission of any cognizable offence, which is made punishable for three years or more but less than seven years, the officer in charge of the police station may, with the prior permission from an officer not below the rank of Deputy Superintendent of Police… proceed to conduct preliminary enquiry to ascertain whether there exists a prima facie case… within a period of fourteen days…”

In Simple Terms: For mid-range offences the police may take up to 14 days, with a senior’s nod, to check whether the complaint has substance before opening an FIR.
