The two provisions

Section 2(1): “inquiry” means every inquiry, other than a trial, conducted under this Sanhita by a Magistrate or Court — a negative definition, and therefore very wide.

Section 173(3): on receipt of information relating to a cognizable offence punishable with three years or more but less than seven years, the officer in charge may, with the prior permission of an officer not below the rank of Deputy Superintendent of Police, and considering the nature and gravity of the offence, conduct a preliminary enquiry to ascertain whether there exists a prima facie case for proceeding, within a period of fourteen days.

📖 S.N. Sharma v. Bipen Kumar Tiwari, (1970) 1 SCC 653

Facts: A Magistrate was moved to interfere with an investigation in progress, on the footing that the provision empowering him to hold an inquiry into a police investigation gave him a general supervisory power over its conduct.

Held: The Supreme Court held that the power of the police to investigate a cognizable offence is a statutory power on which the Magistrate has no control, and that the provisions of the Code do not confer on a Magistrate any authority to interfere with an investigation or to stop it. The Court held that the provision permitting a Magistrate to hold a preliminary inquiry into a police investigation, or to direct one, is a limited power for a limited purpose, and is not a general supervisory jurisdiction over the manner in which the police proceed. It reasoned that the spheres of the police and of the court are distinct: the police investigate, and the court’s function begins when the result of the investigation is placed before it. The Court held that where an investigation is said to be improper, the remedy lies elsewhere — in an application to a superior police officer, or in the court’s consideration of the report when it comes — and not in a direction to the police about how to investigate.

Ratio: The power of the police to investigate is a statutory power on which the Magistrate has no control, and no provision confers authority to interfere with or stop an investigation. A power to hold a preliminary inquiry is a limited power for a limited purpose, not a supervisory jurisdiction.

📖 P. Sirajuddin v. State of Madras, (1970) 1 SCC 595

Facts: A case was registered against a senior public servant and an investigation launched without any prior verification of the allegations, with consequences for his position and reputation which the Supreme Court considered required a different approach at the threshold.

Held: The Supreme Court held that before a public servant of standing is subjected to the indignity and the damage to reputation which the registration of a case and an open investigation necessarily bring, there should be a preliminary enquiry to satisfy the authorities that there is substance in the allegation. The Court held that such an enquiry is not an investigation: its purpose is only to ascertain whether the complaint has any substance, it confers no power of arrest or of compelling attendance, and it must be completed with expedition so that it does not become a means of keeping a person under indefinite suspicion. The Court emphasised that the enquiry should be conducted discreetly, and that the person concerned should ordinarily be given an opportunity to explain before the matter goes further — but that once the material discloses an offence, the ordinary machinery must take its course and the enquiry cannot be used to shield anyone.

Ratio: Before a public servant of standing is exposed to the damage which registration and open investigation bring, a preliminary enquiry should ascertain whether there is substance in the allegation. Such an enquiry is not an investigation and confers no power of arrest or compulsion.

⚠ Four propositions worth holding

An inquiry is judicial, and carries the safeguards of its provision. Where the provision requires notice, a hearing or the recording of evidence, those requirements apply — as under section 196 for a custodial death, or section 223 for a complaint.

A preliminary enquiry is not an investigation. It confers no power of search, seizure or arrest. Those arise only on registration, and an officer who exercises them during an enquiry acts without authority.

Its scope is confined to one question: whether the information discloses a cognizable offence. Not the truth of the allegation, not the credibility of the informant, not the likelihood of conviction.

And it is neither mandatory nor always permissible. Where the information already discloses a cognizable offence, registration is mandatory and the enquiry is superfluous; and outside the three-to-seven-year band there is no power to hold one at all.

The position stated shortly

1. An inquiry is every inquiry other than a trial conducted by a Magistrate or Court — a judicial proceeding.

2. A preliminary enquiry under section 173(3) is a police step taken before any FIR exists — an executive act.

3. A preliminary enquiry requires the prior permission of an officer not below the rank of Deputy Superintendent, is confined to offences punishable with three years or more but less than seven, and must be completed within fourteen days.

4. An inquiry decides the question its provision requires; a preliminary enquiry decides only whether a cognizable offence is disclosed.

5. The police power to investigate is a statutory power on which the Magistrate has no control, and no provision permits him to interfere with or stop an investigation: S.N. Sharma.

6. A power to hold a preliminary inquiry into an investigation is a limited power for a limited purpose, not a supervisory jurisdiction.

7. The origin of the preliminary enquiry is the need to spare a person the damage to reputation which registration and open investigation bring, where the allegation may have no substance: P. Sirajuddin.

8. But such an enquiry is not an investigation, confers no power of arrest or compulsion, and must be completed with expedition.

9. Section 173(3) disciplines that discretion — a defined band, a rank requirement, and a fourteen-day limit.

10. And it is neither mandatory nor always permissible: where the information already discloses a cognizable offence, registration is mandatory.
