The Central Bureau of Investigation is India's premier investigation agency. Its operations across States are governed by a critical federal provision: Section 6 of the Delhi Special Police Establishment Act 1946, which requires State consent before the CBI can investigate offences in any State. This consent requirement has become a flashpoint in Centre-State relations — multiple States have withdrawn "general consent" in recent years, requiring the CBI to seek case-specific consent. The Supreme Court has held that Article 142 (complete justice) can override Section 6 in appropriate cases. The constitutional question of whether the consent requirement is itself a basic feature of federalism remains live. Hold the architecture, the operational practice, and the federal politics carefully.
CBI — institutional architecture
The Central Bureau of Investigation's legal architecture is unusual. The CBI itself was established by an executive resolution of the Government of India in 1963, not by statute. But the CBI exercises police powers under the Delhi Special Police Establishment Act 1946 (DSPE Act) — a colonial-era statute originally enacted to police the special needs of the Delhi area.
The constitutional architecture is layered:
(i) Source of police power. The CBI's police powers derive from the DSPE Act 1946. The Act establishes the Delhi Special Police Establishment as a force capable of investigating specified categories of offences.
(ii) Investigation jurisdiction. Under Section 3 of the DSPE Act, the Central Government can specify, by notification, the offences that the DSPE (now CBI) can investigate. These include offences under the Prevention of Corruption Act, the Indian Penal Code, and various special Acts. The list of notified offences has expanded substantially since 1946.
(iii) Geographical jurisdiction. Under Section 5 of the DSPE Act, the Central Government can extend the DSPE's powers and jurisdiction to "any area" of India — but with the Section 6 consent requirement.
(iv) Composition. The CBI is headed by a Director, with the rank of Director of Police. Specialised divisions handle: Anti-Corruption (offences under PoC Act); Special Crime (offences against public servants); Economic Offences (financial fraud, securities offences); Special Investigation (specific assignments).
CBI Director — appointment. Section 4A of the DSPE Act (added by amendment, codifying the Vineet Narain judgment) provides that the Director is appointed by a committee:
(i) Prime Minister — Chairperson;
(ii) Leader of Opposition in Lok Sabha;
(iii) Chief Justice of India OR a Supreme Court Judge nominated by the CJI.
Tenure. Section 4B — fixed tenure of two years (post-Vineet Narain). Subsequent amendments allowed extensions up to five years total in specific circumstances.
Removal. The Director can be transferred or removed before the term ends only with the consent of the Selection Committee. This protects the Director from arbitrary executive removal.
Section 6 — State consent requirement
Section 6 of the DSPE Act provides: "Nothing contained in section 5 [extending CBI's powers and jurisdiction] shall be deemed to enable any member of the Delhi Special Police Establishment to exercise powers and jurisdiction in any area in a State, not being a Union Territory or railway area, without the consent of the Government of that State."
Three operative elements:
One — consent required for State investigations. The CBI cannot investigate any matter in a State without State consent. The consent must be of the State Government — typically through the Department of Home Affairs.
Two — Union Territories and railway areas excluded. The CBI can operate in Union Territories without consent (since UTs are administered by the Centre). Similarly, railway areas — given the federal nature of railways under the Union List.
Three — consent extends to investigations within the State. The consent requirement applies to investigations of offences committed within the State's territory. Even if the offence has Centre-related elements (e.g., corruption by Central officers), if the location is in a State, consent is needed.
Two types of consent:
General consent. A State can give "general consent" — covering categories of offences and broad classes of public servants. Most States historically gave general consent. With general consent, the CBI can take up cases within the consented categories without seeking case-specific permission.
Specific consent. A State can give consent for a specific case. The CBI must apply each time and the State decides on the merits.
The general consent regime evolved as a federal compromise — States cooperate with CBI as a national agency, but retain the formal power to deny consent.
The Centre's position. The Centre has historically argued that the CBI is a national agency for offences with national implications (corruption by Central officers, large-scale economic offences). State consent should be routine. Withholding consent obstructs national investigation.
The States' position. Police is a State subject (Entry 2 of List II). Investigation is part of police powers. The CBI is a Central agency operating in State territory. Consent is the constitutional concession; States retain the right to control investigations within their borders.
Withdrawal of general consent
The most consequential recent development on Section 6 has been the withdrawal of general consent by several States.
Historical pattern. Most States gave general consent for CBI investigations under specified categories of offences (typically PoC Act offences and certain other Central Acts). The CBI operated relatively freely across States.
Recent withdrawals. Beginning in the late 2010s, several Opposition-ruled States have withdrawn their general consent:
West Bengal — withdrew general consent in November 2018, citing political misuse of the CBI.
Andhra Pradesh — under the YSRCP government, withdrew consent in 2018 (later restored).
Maharashtra — the MVA government withdrew consent in October 2020.
Kerala — withdrew general consent in November 2020.
Tamil Nadu — withdrew general consent in 2021.
Punjab — withdrew general consent in 2022.
Other States — Mizoram, Meghalaya, Jharkhand, Telangana, Chhattisgarh have variously restricted CBI access.
Withdrawal of general consent does not bar the CBI from investigating in the State entirely. The CBI must seek specific consent for each case. The State examines the request and decides. In practice, this slows investigations and can effectively block politically sensitive cases.
Federal politics. Critics argue the withdrawal of general consent is partisan — Opposition States restrict CBI access fearing politically-motivated investigations against their leaders or governments. Supporters argue this is a legitimate exercise of constitutional federalism — States cooperating only on specific cases on merits.
The Supreme Court has not directly addressed the constitutionality of general consent withdrawal as a category. Various petitions have been filed; specific cases have been decided on facts. The basic structure question — is the consent regime itself a federal feature, or can the Centre assert national investigation jurisdiction without it — remains live.
Article 142 override and judicial workarounds
The Supreme Court has held that Section 6's consent requirement does NOT bind the Court itself. Under Article 142 (complete justice), the Court can direct CBI investigation even without State consent.
This was articulated in Delhi Judicial Service Association v. State of Gujarat (1991) and reaffirmed in subsequent cases. The Court's reasoning:
(i) Article 142 is a constitutional provision. Section 6 is a statutory provision.
(ii) Constitutional provisions cannot be limited by statutory provisions.
(iii) Where the Court considers it necessary for "complete justice," it can direct CBI investigation without State consent.
The Court has emphasised that this power is to be used sparingly — not as a routine workaround for States that have withdrawn consent. But in extraordinary circumstances (high-profile cases, political deadlock, allegations of State complicity in offences), the Court can step in.
Use of Article 142 to direct CBI investigations has occurred in several landmark cases:
(i) Vineet Narain v. Union of India (1997) — Hawala scandal investigations directed.
(ii) Subramanian Swamy v. Union of India (2014) — 2G spectrum case investigations.
(iii) Various other public interest petitions where the Court has felt that State authorities cannot or will not investigate adequately.
The Article 142 override has been criticised. Some argue it undermines federalism — the Court can bypass State consent requirements that the Constitution itself preserves. Others argue it is a necessary safeguard — the Court can ensure investigation in exceptional cases where State authorities fail.
The High Courts under Article 226 have also directed CBI investigations in specific cases — though their power is more constrained than the Supreme Court's under Article 142.
Other workarounds:
(i) Multi-State investigations. If an offence involves multiple States, the CBI can investigate based on consent from any of them — with the Centre arguing that consent is for the locus of offence, not for each State where investigation extends.
(ii) Concurrent investigation. The CBI may continue investigations that began before consent was withdrawn — with State authorities arguing that the withdrawal applies prospectively only.
(iii) Court-monitored cases. When a case is being monitored by the Supreme Court or a High Court, the CBI can continue investigation even without fresh State consent.
CBI in the wider investigation architecture
The CBI exists within a wider architecture of investigation agencies, each with specific roles:
State Police — primary investigation agency for offences within States. Investigates almost all crimes.
CBI — investigates specific Central offences (notified under Section 3 of DSPE Act): Prevention of Corruption Act offences; offences against public servants; economic offences; specific high-profile cases referred by States or directed by courts.
Enforcement Directorate (ED) — investigates offences under the Prevention of Money Laundering Act 2002 (PMLA) and the Foreign Exchange Management Act 1999 (FEMA). The ED has expanded considerably in scope and use over recent years.
National Investigation Agency (NIA) — established under the National Investigation Agency Act 2008 after the 26/11 Mumbai attacks. Investigates offences against national security, terrorism, hijacking, and related matters. The NIA can investigate in any State without State consent (a deliberate departure from the CBI model).
Income Tax Department — investigates income tax-related offences.
Directorate of Revenue Intelligence (DRI) — investigates customs offences, smuggling.
Other agencies — Narcotics Control Bureau, RAW, Intelligence Bureau, etc., for specialised matters.
The NIA Act distinction. The NIA Act 2008 explicitly empowers the NIA to investigate offences without State consent — a different legal architecture from the CBI. This has been justified as necessary for national security investigations. The NIA model has been pointed to as a possible reform path for the CBI — replacing the consent regime with a more direct national mandate. No such reform has been enacted.
The constitutional question remains open: should the CBI continue to operate under the consent regime, or should there be a national investigation agency for non-security Central offences with direct jurisdiction across States? Reform proposals exist; legislation has not followed.
Reform debates — constitutional status, autonomy, jurisdiction
Several reform proposals have been made for the CBI architecture.
One — Constitutional status. Proposals to give CBI constitutional status (similar to NCSC, ECI). This would: (a) protect CBI from being abolished by ordinary legislation; (b) provide stronger institutional protection; (c) clarify the scope of consent requirement.
Two — Statutory framework for CBI itself. The CBI was established by executive resolution; a comprehensive CBI Act would clarify its powers, structure, and accountability. Multiple drafts have been prepared; none enacted.
Three — End of consent regime. Some proposals advocate replacing the consent regime with an NIA-style direct jurisdiction for specified Central offences. This would address the concerns about State withdrawals undermining national investigations. Critics argue this would erode federalism.
Four — Supreme Court oversight. Proposals for institutional Supreme Court oversight of CBI investigations of high-profile cases — to ensure independence from political pressure.
Five — Better resources and personnel. Calls for substantial increase in CBI staff, training, technology, infrastructure. The CBI handles a large workload with relatively limited resources.
Six — Lokpal coordination. Clear protocols for when CBI investigates and when Lokpal directly investigates — to avoid jurisdictional overlap.
The Supreme Court in Vineet Narain (1997) emphasised that CBI independence is essential. The Selection Committee for the Director (PM, LoP, CJI) and the fixed tenure provisions were direct outcomes. Further reforms have been incremental rather than wholesale.
The basic architecture under the DSPE Act 1946, with executive amendments and judicial directions, continues. The consent regime under Section 6 has not been fundamentally altered despite the recurring federal tensions.
What students must hold
Six points carry the weight. One, CBI was established by executive resolution in 1963. Police powers from Delhi Special Police Establishment Act 1946 (a colonial statute). The CBI is itself non-statutory; the DSPE Act gives it the legal framework.
Two, Section 6 of DSPE Act — CBI cannot investigate in a State without State consent. Excludes Union Territories and railway areas. Consent can be GENERAL (broad categories) or SPECIFIC (case-by-case).
Three, withdrawal of general consent: West Bengal (2018), Maharashtra (2020), Kerala (2020), Tamil Nadu (2021), Punjab (2022), and others. These States now require case-specific consent for CBI investigations.
Four, Article 142 override — Supreme Court can direct CBI investigation without State consent under Article 142 (Delhi Judicial Service Association v. State of Gujarat 1991, Vineet Narain 1997). Statutory provisions cannot limit constitutional powers.
Five, CBI Director — appointed by committee of PM (Chair), LoP, CJI/SC Judge (Section 4A of DSPE Act, codifying Vineet Narain). Fixed tenure of 2 years (extendable). Cannot be transferred or removed before term without committee consent.
Six, NIA distinction — National Investigation Agency under NIA Act 2008 does NOT require State consent. Different model — operates directly across States. CBI continues under consent regime. For more, see CVC and Supreme Court jurisdiction.
