The Delhi Special Police Establishment Act, 1946

This Act of eleven sections is the legal foundation of the Central Bureau of Investigation. There is no statute constituting the CBI: it was created by a resolution of the Ministry of Home Affairs in 1963, and every power it exercises as a police force is drawn from the Delhi Special Police Establishment Act, 1946. The Act constitutes a special police force for the Union territories, permits the Central Government to notify the offences it may investigate, allows its jurisdiction to be extended to the States, and then makes that extension conditional on the consent of the State concerned. Almost every controversy about the agency turns on one of those four features.

1. Origin and Constitutional Basis

1941. A Special Police Establishment was created by executive order under the War Department to investigate bribery and corruption in transactions connected with war supplies. It had no statutory basis and its jurisdiction depended on the Government's control over its own departments.
1946. With the war over and the need continuing, the Delhi Special Police Establishment Ordinance was promulgated and replaced by the Delhi Special Police Establishment Act, 1946. The force was placed under the Home Department, and its jurisdiction extended to all departments of the Government of India.
1963. The Central Bureau of Investigation was established by a resolution of the Ministry of Home Affairs dated 1 April 1963, with divisions for investigation, records and statistics, and technical work. The investigative arm of the CBI is the Delhi Special Police Establishment constituted under this Act, which is why the two names are used interchangeably.
2003. The Central Vigilance Commission Act transferred superintendence over corruption investigations to the Commission, created a statutory committee for the appointment of the Director, and inserted Section 6A.
2013 and 2014. The Lokpal and Lokayuktas Act recast the appointment committee and created a Directorate of Prosecution; the amendment of 2014 provided for the leader of the single largest opposition party where there is no recognised Leader of the Opposition.
2021. The tenure provision was amended to permit the Director's period in office to be extended by one year at a time, up to a total of five years.

The constitutional foundation is Entry 80 of List I of the Seventh Schedule, which permits the extension of the powers and jurisdiction of members of a police force belonging to any State to any area outside that State, but not so as to enable the police of one State to exercise powers in another without the consent of the Government of that State. Police and public order are State subjects under Entries 1 and 2 of List II. The whole architecture of the Act, and in particular the consent requirement in Section 6, follows from that division.

📖 Advance Insurance Co. Ltd. v. Gurudasmal, (1970) 1 SCC 633

Held: The constitutional validity of the Act was upheld. The Delhi Special Police Establishment is a police force of the Union territory of Delhi, and Parliament was competent to enact the statute. Its members may exercise powers in a State by virtue of the extension made under Section 5, read with the consent of that State under Section 6, which is precisely what Entry 80 of List I contemplates.

Significance: This is the foundational decision on the validity of the Act and on the character of the force as a police force of a Union territory whose reach into the States is consent-based.

2. The Scheme of the Act

The sections of the Act, and the fact that the CBI itself has no statute

Sections 2, 3, 5 and 6, Delhi Special Police Establishment Act, 1946

2(1) Notwithstanding anything in the Police Act, 1861, the Central Government may constitute a special police force to be called the Delhi Special Police Establishment for the investigation in any Union territory of offences notified under section 3.

2(2) Subject to any orders which the Central Government may make in this behalf, members of the said police establishment shall have throughout any Union territory, in relation to the investigation of such offences and arrest of persons concerned in such offences, all the powers, duties, privileges and liabilities which police officers of that Union territory have in connection with the investigation of offences committed therein.

2(3) Any member of the said police establishment of or above the rank of Sub-Inspector may exercise any of the powers of the officer in charge of a police station in the area in which he is for the time being.

3 The Central Government may, by notification in the Official Gazette, specify the offences or classes of offences which are to be investigated by the Delhi Special Police Establishment.

5(1) The Central Government may by order extend to any area, including railway areas, in a State, not being a Union territory, the powers and jurisdiction of members of the Delhi Special Police Establishment for the investigation of any offences or classes of offences specified in a notification under section 3.

6 Nothing contained in section 5 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.

⚠ The notification under Section 3 is the source of subject-matter jurisdiction

The agency cannot investigate an offence merely because it is serious or because the Central Government wishes it to. The offence must fall within a notification issued under Section 3, which lists offences under the Prevention of Corruption Act, 1988, a large number of offences under the general penal law and a long schedule of offences under central enactments. Where an offence is not notified, the agency has no power to investigate it even in a Union territory, and even with the consent of a State.

3. Superintendence and Administration: Section 4

Section 4, as it stands after the Central Vigilance Commission Act, 2003, divides control three ways. The superintendence of the Establishment, in so far as it relates to the investigation of offences alleged to have been committed under the Prevention of Corruption Act, 1988, vests in the Central Vigilance Commission. Save as so provided, the superintendence vests in the Central Government. The administration of the Establishment vests in the Director, who exercises in respect of it such of the powers exercisable by an Inspector-General of Police as the Central Government may specify.

📖 Vineet Narain v. Union of India, (1998) 1 SCC 226

Held: In the Jain hawala matter the Supreme Court, proceeding by continuing mandamus, found that investigations into allegations against persons in high places had been stalled and that the agency lacked the insulation to pursue them. It struck down the single directive, an executive instruction requiring prior approval of the Government before an inquiry could be initiated against officers above a stated rank. It directed that the Central Vigilance Commission be given statutory status and be entrusted with the superintendence of corruption investigations, that the Director be selected by a committee and have a minimum tenure of two years, and that the Government have no role in the day to day functioning of the agency.

Significance: Almost the whole of the present Sections 4, 4A and 4B originates in these directions, which the Central Vigilance Commission Act, 2003 afterwards enacted. The case is also the leading authority on continuing mandamus as a technique.

4. The Director: Sections 4A, 4B, 4BA and 4C

The appointment committee, the tenure, the protection from transfer, and their origin

Section 4A, the committee. The Central Government appoints the Director on the recommendation of a committee consisting of the Prime Minister as Chairperson, the Leader of the Opposition in the House of the People, or where there is no such Leader, the leader of the single largest opposition party in that House, and the Chief Justice of India or a Judge of the Supreme Court nominated by him. A vacancy in the committee does not invalidate its recommendation.
Section 4B, tenure. The Director holds office for not less than two years from the date on which he assumes office, notwithstanding anything to the contrary in the rules relating to superannuation. After the amendment of 2021 the period may be extended, in the public interest and for reasons recorded in writing, by one year at a time, so that the total period does not exceed five years.
Section 4B(2), protection from transfer. The Director shall not be transferred except with the previous consent of the committee referred to in Section 4A.
Section 4BA, prosecution. There shall be a Directorate of Prosecution headed by a Director of Prosecution, who is an officer not below the rank of a Joint Secretary to the Government of India and who functions under the overall supervision and control of the Director.
Section 4C, senior appointments. A committee headed by the Central Vigilance Commissioner recommends officers for appointment to posts of the level of Superintendent of Police and above, other than the Director, and considers extension or curtailment of their tenure.

📖 Alok Kumar Verma v. Union of India, (2019) 3 SCC 1

Held: The Director of the CBI had been divested of his powers and functions and sent on leave by orders of the Central Government and the Central Vigilance Commission. The Supreme Court held that the protection in Section 4B(2) is not confined to a formal transfer: any action that has the effect of removing the Director from the exercise of his functions requires the previous consent of the committee under Section 4A. The orders were set aside, though the Court left the committee free to consider the matter.

Significance: The decision gives the tenure protection substance. A Government that cannot transfer the Director cannot achieve the same result by divesting him of his work.

5. Extension of Jurisdiction and the Consent of the State

The forms of consent, the effect of withdrawal, and what happens when consent is absent

Sections 5 and 6 work together. Section 5 permits the Central Government to extend the powers and jurisdiction of members of the Establishment to any area in a State. Section 6 provides that nothing in Section 5 enables them to exercise those powers in a State without the consent of the Government of that State. The consent may be general, given as a standing arrangement, or specific to a named case. A State that has given general consent may withdraw it, and several States have done so; the agency may then enter that State only with case-specific consent or under the direction of a constitutional court.

📖 Kazi Lhendup Dorji v. Central Bureau of Investigation, 1994 Supp (2) SCC 116

Held: The withdrawal by a State Government of the consent given under Section 6 operates prospectively. It does not affect an investigation validly commenced while the consent subsisted, and does not require such an investigation to be abandoned.

Significance: This is the answer to the argument that a State can stop an ongoing investigation by withdrawing consent, and it explains why withdrawal matters for future cases rather than for pending ones.

📖 Fertico Marketing and Investment (P) Ltd. v. Central Bureau of Investigation, (2021) 2 SCC 525

Held: Where an investigation is conducted without the consent required by Section 6, the defect is an irregularity and not an illegality going to the root of the matter. Applying the principle in Section 465 of the Code of Criminal Procedure, 1973, the trial is not vitiated unless the accused shows that a failure of justice has in fact been occasioned. Post facto consent by the State was also held to cure the defect on the facts.

Significance: The decision limits the consequences of a want of consent, and it is the authority to cite where an accused seeks to have proceedings quashed on that ground alone.

⚠ The suit under Article 131

The withdrawal of general consent by several States, and the registration of cases in those States notwithstanding, produced litigation of a new kind. In 2024 the Supreme Court held that an original suit filed by the State of West Bengal against the Union of India under Article 131, complaining that the CBI continued to register and investigate cases in the State after the general consent had been withdrawn, was maintainable. The Union's objection that the agency is an independent body and not the Union was rejected at the preliminary stage. The merits remain to be decided, and the case is the current focus of the consent controversy.

6. Investigation Directed by a Constitutional Court

📖 State of West Bengal v. Committee for Protection of Democratic Rights, (2010) 3 SCC 571

Held: A Constitution Bench held that the High Court in exercise of its power under Article 226 and the Supreme Court under Article 32 may direct the CBI to investigate an offence committed within a State without the consent of that State. Section 6 restricts the executive power of the Union; it does not and cannot restrict the constitutional power of the courts, which is part of the basic structure. The power is to be exercised sparingly, cautiously and in exceptional situations, where it becomes necessary to provide credibility and instil confidence in the investigation, or where the allegation has national or international ramifications.

Significance: This is the single most important decision on the Act. It explains why the CBI appears in States that have withdrawn consent, and it fixes the standard the courts apply before making such a direction.

A magistrate cannot do it. In Central Bureau of Investigation v. State of Rajasthan, (2001) 3 SCC 333 the Supreme Court held that a magistrate acting under Section 156(3) of the Code of Criminal Procedure, 1973 cannot direct the CBI to investigate, since his power extends to the police having jurisdiction in the area, and the Establishment's jurisdiction in a State depends on the notification and the consent.
An accused cannot choose. In Central Bureau of Investigation v. Rajesh Gandhi, (1996) 11 SCC 253 it was held that no accused has a right to insist that the offence be investigated by a particular agency, and that the choice of agency is not a matter of right.
Nor, ordinarily, can a complainant. A direction to transfer an investigation is not made merely because the informant is dissatisfied with the State police; something more, going to the credibility of the investigation, must be shown.

7. Section 6A and Its Fall

Section 6A, inserted by the Central Vigilance Commission Act, 2003, provided that the Establishment shall not conduct any inquiry or investigation into an offence alleged to have been committed under the Prevention of Corruption Act, 1988 except with the previous approval of the Central Government where the allegation related to employees of the Central Government of the level of Joint Secretary and above, and to officers appointed by the Central Government in corporations, government companies and other bodies owned or controlled by it. It was, in substance, the single directive that Vineet Narain had struck down, re-enacted in statutory form.

📖 Subramanian Swamy v. Director, Central Bureau of Investigation, (2014) 8 SCC 682

Held: A Constitution Bench declared Section 6A unconstitutional and violative of Article 14. The classification between senior and junior public servants for the purpose of even initiating an inquiry into corruption has no rational nexus with the object of the Prevention of Corruption Act, 1988, which is to root out corruption at all levels. The provision obstructed the tracking of bribe givers and takers, destroyed the element of surprise essential to such an investigation, and gave protection to a class that the Act itself does not distinguish. The declaration was held to operate retrospectively.

Significance: The decision removed the requirement of prior approval for an inquiry against senior officers. Its effect has been qualified in practice by Section 17A of the Prevention of Corruption Act, 1988, inserted in 2018, which requires previous approval before a police officer conducts any inquiry or investigation into an offence alleged to have been committed by a public servant where the alleged offence relates to a recommendation made or a decision taken in the discharge of official functions. The protection is differently framed, applies to all public servants rather than to senior officers alone, and is confined to acts done in the discharge of duty.

8. Powers, Procedure and Limits

Question	The position
Are its members police officers?	Yes; Section 2(2) gives them the powers, duties, privileges and liabilities of police officers of the Union territory, so the criminal procedure law applies to their investigation as to any other
Who may register a case?	An officer of or above the rank of Sub-Inspector, who may exercise the powers of an officer in charge of a police station under Section 2(3)
Is a confession to them admissible?	No; the bar on confessions to a police officer applies, since they are police officers
Which offences?	Only those notified under Section 3; the notification is the source of subject-matter jurisdiction
Where?	In a Union territory as of right; in a State only under an order under Section 5 and with consent under Section 6, or under a direction of a constitutional court
Sanction to prosecute	Required under Section 19 of the Prevention of Corruption Act, 1988 and, where applicable, under the provision of the criminal procedure law protecting public servants
Superintendence	The Central Vigilance Commission for corruption cases; the Central Government otherwise; and the Lokpal in respect of matters referred by it

9. The Standing Criticisms

No statute of its own. The CBI rests on a resolution of 1963 and borrows its police powers from an Act of 1946 that does not name it. In Navendra Kumar v. Union of India the Gauhati High Court held in 2013 that the resolution was not a law and that the CBI was not a validly constituted police force; the judgment was stayed by the Supreme Court and the question remains open. Every Parliamentary committee that has examined the subject has recommended a separate statute.
Dependence on State consent. A national investigating agency whose entry into a State depends on that State's consent is vulnerable to the politics of the day, and the withdrawal of general consent by several States since 2018 has made the difficulty acute.
Perception of control. In the coal blocks matter the Supreme Court described the agency as a caged parrot speaking in its master's voice, a remark made in the context of a status report shared with the executive before being filed in court. The remark is quoted so often that its context is worth remembering: it was directed at interference with a specific investigation, and it led to directions on insulating the agency.
Resources and outcomes. The agency is chronically short of officers, particularly at the level of prosecutors and technical staff, and the rate of conviction and the pendency of its cases are regularly criticised by the Central Vigilance Commission in its annual reports.

⚠ Reform proposals

Three have been made repeatedly: a comprehensive statute constituting the agency, defining its powers and providing for its accountability, in place of the present arrangement; a restructuring of the consent requirement, so that jurisdiction over notified central offences does not depend on State consent, which would require an amendment and would raise questions under the federal scheme; and financial and administrative autonomy, including a separate cadre and an independent prosecution wing. None has been enacted.
