Central Bureau of Investigation: Superintendence, the Director's Fixed Tenure, and State Consent

The Central Bureau of Investigation has no Act of its own. It was named "CBI" by a 1963 Home Ministry resolution, but its actual legal power to investigate comes entirely from the Delhi Special Police Establishment Act, 1946 (DSPE Act), a statute that predates the CBI's own name by seventeen years and was written for a different, older organisation altogether: the wartime Special Police Establishment, set up in 1941 to investigate corruption in War & Supply Department dealings.

Two different superintending authorities (Section 4)

Section 4 splits superintendence of the DSPE in two, and this split is the chapter's single most tested fact. Superintendence over investigations into offences under the Prevention of Corruption Act, 1988 vests in "the Commission", meaning the Central Vigilance Commission. Superintendence over everything else the DSPE does vests in the Central Government. The CBI is therefore not supervised by one body for all purposes: its anti-corruption casework answers to the CVC, its other work answers to the Central Government directly, most often routed through the Department of Personnel and Training.

Appointing and protecting the Director (Sections 4A and 4B)

The Director is appointed by the Central Government on the recommendation of a three-member committee: the Prime Minister (Chairperson), the Leader of the Opposition in the Lok Sabha (or the leader of the single largest Opposition party if no recognised Leader of the Opposition exists), and the Chief Justice of India or a Supreme Court Judge the CJI nominates. This committee is worth contrasting directly with the CVC's own three-member appointing committee (Prime Minister, Home Minister, Leader of the Opposition): both replace the Home Minister's seat with the judiciary's in the CBI's case, precisely because the CBI is itself the body the CVC's oversight and the government's own conduct are sometimes under investigation by.

The Director's own tenure is separately protected. Section 4B fixes a minimum term of two years from the date of assuming office, extendable only one year at a time, in the public interest, on the same committee's recommendation, with reasons recorded in writing, and capped at five years in total including the initial term (the specific one-year-at-a-time extension mechanism was added by the DSPE (Amendment) Act, 2021). The Director additionally cannot be transferred without the committee's prior consent. Both protections exist for the same reason: to prevent a Director's tenure or posting from being used as leverage over an investigation.

State consent: why the DSPE Act needs it at all

The DSPE Act's very name signals its original, narrow scope: a police force "in Delhi," meaning originally the Union Territories, not the states. Section 5 lets the Central Government extend the DSPE's jurisdiction into a state, but Section 6 then places a real limit on that extension: nothing in Section 5 authorises a DSPE member to exercise powers in a state's territory "without the consent of the Government of that State." This is not a formality tested once and forgotten: a state can, and several have, withdraw this "general consent" at different points, after which the CBI needs the state's specific, case-by-case consent before it can even begin investigating a fresh matter there (cases already under investigation, and matters referred by a court, are not affected by a withdrawal). Because which states currently have general consent withdrawn changes over time, treat the mechanism, not any particular list of states, as the fact worth memorising, and check current affairs for who currently stands where.

Quick revision points

• No CBI Act exists; the CBI runs entirely on the DSPE Act, 1946, a statute written for the wartime Special Police Establishment (1941), not for the CBI, which only got its name by a 1963 resolution.
• Section 4: superintendence over Prevention of Corruption Act cases vests in the CVC; superintendence over everything else vests in the Central Government.
• Director's appointment committee (Section 4A): PM, Leader of the Opposition, CJI or nominee. Contrast with the CVC's own committee (PM, Home Minister, Leader of the Opposition).
• Director's term (Section 4B): minimum 2 years, extendable 1 year at a time up to 5 years total (2021 Amendment), no transfer without the committee's consent.
• Section 6: DSPE members need the state government's consent to operate in that state's territory; withdrawing "general consent" forces the CBI to seek case-by-case permission going forward.

The superintendence split and the two different appointing committees (CBI's versus the CVC's) are the two facts this chapter's questions rely on most; keep them as a contrasting pair rather than learning either body in isolation.
