Vigilance Manual (Updated 2021) — Central Bureau of Investigation: Role, Jurisdiction and CVC-CBI Coordination

A Wartime Anti-Corruption Cell That Outgrew Its Name

The CBI's institutional lineage goes back to the Special Police Establishment (SPE), set up in 1941 to investigate bribery and corruption in the War and Supply Department during the Second World War, headquartered at the time in Lahore. The Delhi Special Police Establishment Act, 1946 expanded its scope to all Departments of the Government of India, gave it jurisdiction over Union Territories, and allowed it to be extended, with a State's consent under Section 6 of the Act, to specific areas of that State for specified offences. The full text of the Act is maintained on the DoPT Acts page. The CBI itself only came into existence later, through a Home Ministry Resolution dated 1 April 1963, with the SPE folded in as one of its constituent wings — specifically the wing that investigates corruption offences, which is why so much of CBI's governing law is still, technically, the DSPE Act rather than a standalone CBI statute.

Sharing Jurisdiction With State Police Without Duplicating It

Technically, the CBI's Anti-Corruption Division has concurrent investigation and prosecution powers with the respective State Police under the Code of Criminal Procedure (now the Bharatiya Nagarik Suraksha Sanhita — more on that below). In practice, an administrative understanding avoids two agencies working the same case: matters substantially concerning Central Government employees or Central Government affairs are investigated by the SPE, with the State Police kept informed and assisting where needed; matters substantially concerning State Government employees or affairs go the other way, with SPE informed and assisting if necessary. Where a State Police investigation happens to implicate a Central Government employee, the request for sanction to prosecute that employee is routed through the SPE rather than handled directly by the State.

The Vineet Narain Case and Exactly How Far the Commission's Supervision Goes

The defining moment in CBI-CVC relations is the Supreme Court's judgment of 18 December 1997 in Vineet Narain v. Union of India [1 SCC 226] — a case that grew out of frustration at how slowly politically sensitive corruption investigations (the Jain hawala diaries matter) were moving. The Court directed that the CVC be made statutorily responsible for the CBI's efficient functioning, which led directly to the CVC Act, 2003, and a corresponding amendment to Section 4 of the DSPE Act, effective 1 September 2003.

The amended Section 4 splits authority carefully into three distinct pieces: superintendence over investigation of Prevention of Corruption Act offences vests in the Commission; superintendence over every other matter vests in the Central Government; and the day-to-day administration of the SPE vests in an officer appointed by the Central Government — the Director — exercising powers broadly equivalent to a State's Inspector-General of Police. Section 8(1) of the CVC Act mirrors this split, and adds one crucial limitation: the Commission may give directions to the DSPE for discharging its Section 4(1) responsibility, but it cannot direct the DSPE to investigate or dispose of any particular case in a particular manner. This is worth sitting with, because it's the exact boundary that keeps the Commission's role as supervisory oversight rather than a case-by-case controller — the Commission can ask why a category of cases is moving slowly, but it cannot instruct the CBI on what to conclude about any one of them.

Section 6A — The Approval a Senior Officer's File Needs Before It Can Even Open

This is the piece most officers below Joint Secretary level never have reason to learn, and the one that matters most to anyone above it. Section 6A of the DSPE Act requires the previous approval of the Central Government before the Delhi Special Police Establishment can even conduct any inquiry or investigation into an offence alleged to have been committed under the Prevention of Corruption Act, 1988, by officers of the level of Joint Secretary and above in the Central Government, and by officers of equivalent level in corporations, bodies and authorities established by or under a Central Act, Government companies, societies, and local authorities owned or controlled by the Central Government.

The provision has a genuinely eventful history. It began as an executive instruction known informally as the “Single Directive,” which the Supreme Court struck down as unconstitutional in the Vineet Narain judgment itself, on the ground that requiring prior executive approval before investigating a senior officer undermined the independence of investigation. Parliament then reintroduced the same protection in statutory form, as Section 6A, via the Central Vigilance Commission Act, 2003. This too was struck down by a Constitution Bench of the Supreme Court in Subramanian Swamy v. Director, CBI [(2014) 8 SCC 682], which held that carving out a separate, higher procedural threshold for a class of officers based purely on seniority violated Article 14's guarantee of equality before the law. Despite that judgment, Parliament reintroduced an approval requirement again in 2018, through amendments to the Prevention of Corruption Act itself — so a version of this protection remains operative in practice, now anchored primarily in the amended PC Act rather than DSPE Section 6A in its original form, though the Section 6A route is still referenced in the Manual and in CBI's own operating instructions. The practical takeaway for a working officer has not changed across all this litigation: if the officer under scrutiny is Joint Secretary-level or above, do not assume the CBI can simply walk in and open a file — check whether the relevant prior-approval requirement has actually been satisfied before treating any resulting investigation as validly initiated.

The Commission's own role also includes reviewing the progress of PC Act investigations and reviewing pending applications for sanction of prosecution under the PC Act, 1988 (Sections 8(1)(e) and 8(1)(f) of the CVC Act), and it may itself cause an inquiry to be made by the CBI on a Central Government reference or on a complaint within its jurisdiction, with the resulting report forwarded back to the Commission (Section 17, CVC Act).

A Second Layer of Superintendence, Since 2013

Since the Lokpal and Lokayuktas Act, 2013, a parallel superintendence structure exists alongside the Commission's: under Section 25(1) of that Act, the Lokpal has powers of superintendence and direction over the DSPE specifically in respect of matters the Lokpal itself has referred to the DSPE for preliminary inquiry or investigation — subject to the identical restriction that the Lokpal, too, cannot direct how a particular case is investigated or disposed of. In practice, this means a given officer's case could sit under either the CVC's or the Lokpal's superintendence framework depending on how it originated, though the investigating officer's independence on the actual outcome is preserved either way.

Who Appoints Whom — and Why the Process Matters as Much as the Person

The Director of CBI is appointed by the Central Government on the recommendation of a committee comprising the Prime Minister (Chairperson), the Leader of Opposition in the Lok Sabha, and the Chief Justice of India or a Supreme Court Judge nominated by the CJI — a composition deliberately built to prevent the appointment being seen as a purely executive choice. The Director of Prosecution is appointed by the Central Government on the recommendation of the CVC. Officers at the level of Superintendent of Police and above, other than the Director, are appointed — and have their tenure extended or curtailed — on the recommendation of a committee chaired by the Central Vigilance Commissioner, with the Vigilance Commissioners, the Home Secretary, and the Secretary (Personnel) as members, and that committee must consult the Director before finalising its recommendation. The Manual specifically warns against ex-post-facto approvals for tenure extensions; the underlying concern is that an officer's tenure quietly lapsing and then being retrospectively regularised undermines exactly the kind of institutional stability the post-Vineet Narain reforms were meant to build.

How a Case Actually Starts, and the CrPC-to-BNSS Transition

CBI enquiry or investigation begins after verifying either its own source information (recorded as a Source Information Report), information from the public or public servants, or complaints referred by the Commission, administrative authorities, or courts. Where the information is clear and substantial enough on its face to disclose a cognizable offence, a Regular Case is registered directly; where it first needs verification, a Preliminary Enquiry may precede registration. The governing authority here is the Constitution Bench's ruling in Lalita Kumari v. State of UP [(2014) 2 SCC 1], which holds that FIR registration is mandatory once a cognizable offence is disclosed on the face of the information — a preliminary inquiry is permitted only to first ascertain whether a cognizable offence is disclosed at all, not as a routine screening step applied to every complaint regardless of its content.

Once a case genuinely warrants registration, doing so early matters — partly to prevent a suspect from tampering with evidence in the interim. But the Manual also cautions against the opposite excess: SPE should not register a case over a minor procedural flaw alone, and should weigh an officer's overall positive record so that one isolated lapse doesn't overshadow an otherwise clean career — while making clear the law does not bar investigating such matters where they are genuinely warranted on the facts.

A procedural note officers should not miss: the Code of Criminal Procedure, 1973, referenced throughout the printed 2021 Manual, has been substantially replaced by the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, effective 1 July 2024, alongside the Bharatiya Nyaya Sanhita, 2023 (replacing the IPC) and the Bharatiya Sakshya Adhiniyam, 2023 (replacing the Evidence Act). The Prevention of Corruption Act, 1988 remains the substantive law governing corruption offences and its core provisions are unaffected, but every procedural cross-reference in a vigilance file — FIR registration, arrest, search and seizure — should now be checked against the BNSS provisions, not the CrPC section numbers printed in the 2021 edition.
