CVC, CBI, ED and CAG: India’s anti-corruption institutions

India does not suffer from a shortage of anti-corruption institutions. It suffers from a shortage of coordination among them. The CBI investigates, the CVC supervises vigilance across the central government, the ED chases the money trail under money-laundering and foreign-exchange laws, and the CAG audits the books after the fact. Each was designed in a different era for a different problem, and each carries the birth defects of its origin. This article explains their mandates and their limits, and why the sanction bottleneck and turf overlaps keep blunting the sword.

The legal framework these bodies enforce, the PCA and its 2018 amendment, is covered in governance-10-corruption-framework, and the Lokpal, which sits above this architecture, in governance-12-lokpal. The CAG’s constitutional design, its appointment, tenure and the famous audit controversies, belongs to the polity module (polity-12-bodies) and is not repeated here.

The CBI: India’s premier investigating agency

The CBI’s lineage runs from the Special Police Establishment of 1941, set up to probe wartime procurement fraud, through the Delhi Special Police Establishment Act of 1946, to its present name, given by a 1963 Home Ministry resolution. It is an attached office under the Department of Personnel and Training, which places it under the Prime Minister. Its corruption jurisdiction rests on Sections 2, 5 and 6 of the DSPE Act: it can investigate in a state only with that state’s consent, the famous Section 6 general-consent regime.

Three moments define its modern history. In Vineet Narain v. Union of India (1997), the Supreme Court placed CVC superintendence over the CBI in PCA cases, fixed a two-year tenure for the Director, created the appointment committee of the Prime Minister, the Leader of Opposition and the Chief Justice of India, and struck down the “single directive” that had required government approval before probing senior officers. In 2013, during the coal-block hearings, Justice R.M. Lodha called the CBI “a caged parrot, speaking in its master’s voice.” And the CBI (Amendment) Act of 2021 allowed the Director’s tenure to be extended one year at a time up to five years, which critics read as a leash held by the incumbent government.

The federal question is live. After 2018, West Bengal, Maharashtra, Kerala, Rajasthan, Punjab, Jharkhand, Chhattisgarh and Telangana withdrew general consent, forcing the CBI to seek case-by-case permission. The Constitution Bench in State of West Bengal v. Committee for Protection of Democratic Rights (2010) had already wrestled with the CBI’s jurisdiction in a federal structure. This was the exact frame of the 2021 mains question on the CBI’s power to lodge FIRs within states. Operationally, the agency runs with about a third of its posts vacant even as it claims an official conviction rate near 67%.

The CVC: the apex vigilance body

The Central Vigilance Commission was set up in 1964 on the recommendation of the K. Santhanam Committee (1962) and got statutory form through the CVC Act of 2003. It is the apex vigilance institution: it exercises superintendence over the CBI in PCA cases, advises on vigilance matters across central government organisations, and inquires into complaints of corruption by public servants. It consists of a Central Vigilance Commissioner and up to two Vigilance Commissioners, appointed by the President on the recommendation of a committee of the Prime Minister, the Home Minister and the Leader of Opposition in the Lok Sabha.

The PJ Thomas episode tested the design. In Centre for PIL v. Union of India (2011), the Supreme Court quashed the appointment of P.J. Thomas as CVC, holding that the high-power committee must decide by consensus on the integrity of the appointee, not merely by majority vote. The Commission’s members serve four years or until age 65, with salaries equivalent to the UPSC Chairperson and members, charged on the Consolidated Fund of India. But the capacity gap is stark: the CVC operates with less than half its sanctioned strength while overseeing more than 1,500 organisations, as its own 2023 annual report admits.

The ED: following the money

The Enforcement Directorate sits under the Department of Revenue and enforces three very different laws: the Prevention of Money Laundering Act, 2002, the Foreign Exchange Management Act, 1999, and the Fugitive Economic Offenders Act, 2018, with the legacy FERA of 1973 behind them. Its PMLA toolkit is formidable: arrest under Section 19, search and seizure under Section 17, attachment of property for up to 180 days under Section 5, summons under Section 50, the stringent twin conditions for bail under Section 45, and the reverse burden of proof under Section 24.

The Supreme Court’s 2022 decision in Vijay Madanlal Choudhary upheld this architecture: ED officers are not police officers, the Enforcement Case Information Report is not the equivalent of an FIR, and the twin bail conditions and reverse burden stand. A year later, Pankaj Bansal (2023) corrected the process by requiring grounds of arrest to be furnished in writing, and a review is pending before a bench led by Justice Surya Kant. The performance statistics are the critics’ main weapon: Justice Ujjal Bhuyan cited roughly 5,000 ECIRs against fewer than 10 convictions as of 2025, feeding the charge that the ED is used as a political instrument, especially since the same 2021 amendment that touched the CBI extended the ED Director’s tenure too.

The CAG: the auditor in the architecture

The Comptroller and Auditor General is the fourth leg, but a different kind of leg. Where the CBI, CVC and ED chase individual wrongdoing, the CAG audits systems: it covers roughly a quarter of auditable units each year and its reports have repeatedly supplied the raw material for corruption investigations, from the 2G spectrum audit to the Commonwealth Games audit. Its constitutional design, appointment, security of tenure and the controversies around its audits are covered in the polity module’s article on constitutional bodies (polity-12-bodies). The governance-relevant point is the linkage: the CAG finds the systemic leak, the CVC and CBI are supposed to fix the guilty, and the gap between those two steps is where most scandals go to die.

The sanction bottleneck

Every institution in this architecture hits the same wall: the requirement of prior sanction before prosecuting or even investigating a public servant. Section 19 of the PCA requires sanction for prosecution; Section 17A, added in 2018, requires prior approval before enquiry, inquiry or investigation for official acts. Transparency International India reported that over 70% of prosecution sanctions were pending beyond six months in 2023. The result is a system that is architecturally complete and operationally weak: the law exists, the institutions exist, but the permission to act arrives late or not at all.

Turf overlaps: too many cooks

Mandates overlap at the edges. The CVC supervises the CBI in PCA cases but does not control its day-to-day investigations. The ED’s money-laundering probes run parallel to CBI corruption cases on the same facts, with different standards of proof and different political optics. The Lokpal, covered in the next article, was meant to sit above all of them but inherited only a slice of jurisdiction. Add the CAG’s audits, parliamentary committees and the courts, and an anti-corruption drive becomes a multi-agency negotiation. The 2nd ARC’s answer was the single-agency model of Singapore and Hong Kong; India’s answer, so far, has been to add institutions without subtracting any.

What examiners keep asking

• The CBI’s jurisdiction to lodge FIRs and probe within states versus states’ power to withhold consent, in the context of federal character (2021).
• The Vineet Narain reforms: CVC superintendence, fixed tenure and the end of the single directive (a recurring prelims staple).
• Why regulatory and investigative institutions must remain independent and autonomous (2015, asked for regulators but the logic applies to the CBI and ED).

Three watchdogs compared

The CBI, the CVC and the ED are constantly mentioned together and constantly confused. Their mandates overlap at the edges, but their legal DNA is different.

CBI versus ED: the side-by-side

Who leads the ED: appointment and the tenure battle

The ED Director is appointed on the recommendation of a committee that includes the Central Vigilance Commissioner and the Finance, Home, and Personnel Secretaries, with a minimum tenure of two years and committee approval required for any transfer. The Supreme Court has underlined that the appointment is not at the government's sweet will.

That insulation was tested in the tenure battle over Sanjay Kumar Mishra. On 11 July 2023, a bench of Justices B.R. Gavai, Vikram Nath, and Sanjay Karol held that the 2021 and 2022 extensions of his tenure were not valid in law, though it let him continue till 31 July 2023 citing the FATF review and the need for a smooth transition. The Court upheld the 2021 amendments that allow CBI and ED chiefs a two-year term extendable one year at a time up to five years.

The CBI's federal fault line

Mizoram became the first state to withdraw general consent to the CBI in 2015; Maharashtra, Punjab, Rajasthan, West Bengal, Jharkhand, Chhattisgarh, and Kerala followed, forcing the agency to seek case-specific consent. The Supreme Court in Kazi Lendhup Dorji v. CBI (1994) dealt with the Section 6 consent requirement for CBI investigation in a state, and the 2nd ARC's standing recommendation is a dedicated statute giving the CBI statutory footing independent of the 1946 Act.

SFIO: the corporate-fraud investigator

The Serious Fraud Investigation Office is the multi-disciplinary investigating agency under the Ministry of Corporate Affairs, given statutory status by Section 211 of the Companies Act, 2013. It investigates serious corporate frauds, and its powers and staffing were strengthened after the Satyam scandal exposed how easily auditors and boards could fail together.

Key Terms

• Delhi Special Police Establishment Act, 1946: The Delhi Special Police Establishment Act, 1946 is the statute that created the Delhi Special Police Establishment and remains the legal foundation of the Central Bureau of Investigation. It empowers the CBI to investigate notified offences, with the consent of a state government required for operations in that state under Section 6. Example: several states have withdrawn general consent, forcing case-by-case CBI entry. UPSC relevance: federalism and the autonomy of investigative agencies. When a state withdraws general consent, the CBI must seek fresh permission for every new case in that state.
• Prevention of Money Laundering Act, 2002: The Prevention of Money Laundering Act, 2002 (PMLA) criminalises money laundering and empowers the Enforcement Directorate to attach and confiscate tainted property. Enacted in 2002 and enforced from July 2005, it obliges banks and financial intermediaries to report suspicious transactions, and later amendments widened its reach. It anchors India's financial-integrity regime. The ED routinely attaches properties of accused persons during laundering investigations.
• Delhi Special Police Establishment Act: The Delhi Special Police Establishment Act, 1946 is the statute that created the Delhi Special Police Establishment and remains the legal foundation of the Central Bureau of Investigation. It empowers the CBI to investigate notified offences, with the consent of a state government required for operations in that state under Section 6. Example: several states have withdrawn general consent, forcing case-by-case CBI entry. UPSC relevance: federalism and the autonomy of investigative agencies. When a state withdraws general consent, the CBI must seek fresh permission for every new case in that state.
• Foreign Exchange Management Act, 1999: The Foreign Exchange Management Act, 1999 is the law that replaced the stringent Foreign Exchange Regulation Act (FERA) and governs India's external transactions. It regulates foreign exchange dealings, cross-border investment and external trade with the aim of facilitating orderly markets, treating violations as civil offences with monetary penalties enforced by the Enforcement Directorate. For UPSC, the FERA-to-FEMA transition symbolises the shift from control-era suspicion of foreign capital to liberalisation-era management. Enforcement Directorate investigations into alleged forex violations by companies and individuals proceed under FEMA's civil-penalty framework.
• Fugitive Economic Offenders Act, 2018: The Fugitive Economic Offenders Act, 2018 is the law that lets Indian authorities declare a person a fugitive economic offender if they flee the country to evade prosecution for scheduled economic offences above Rs 100 crore. A special court can then order confiscation of the offender's properties in India and abroad. For UPSC, it represents the shift from chasing absconders through slow extradition to striking their assets directly. Vijay Mallya was declared India's first fugitive economic offender by a Mumbai special court in 2019.
• And the CBI (Amendment) Act: This refers to the Delhi Special Police Establishment (Amendment) Act, 2021, which amended the 1946 Act governing the CBI. It lets the CBI Director's fixed two-year tenure be extended by up to one year at a time, for up to three extensions, capping total service at five years, on the committee's recommendation and for recorded reasons in the public interest. It sits at the intersection of agency independence and executive control, a recurring UPSC theme. Example: the Act replaced the November 2021 ordinance and was passed by the Rajya Sabha in December 2021 amid an Opposition walkout.
• FEMA and the FEO Act: FEMA is the Foreign Exchange Management Act, 1999, which replaced FERA in 2000 to regulate foreign exchange transactions, external trade and cross-border payments, treating violations as civil offences. The FEO Act is the Fugitive Economic Offenders Act, 2018, which allows confiscation of properties of offenders who flee India to escape prosecution in cases involving 100 crore rupees or more. Both matter for UPSC under economic offences and financial regulation. Example: FEO Act proceedings against Vijay Mallya and Nirav Modi. FEO Act proceedings against Vijay Mallya and Nirav Modi
• Comptroller and Auditor General: The Comptroller and Auditor General is India's supreme audit institution under Article 148, appointed by the President with a six-year term or until age 65. The CAG audits the accounts of the Union and the states and reports to Parliament and legislatures, acting as the guardian of the public purse. Its reports frequently trigger debates on executive accountability. The CAG's 2010 report on 2G spectrum allocation reshaped telecom policy and public debate.
• Prevention of Corruption Act: The Prevention of Corruption Act, 1988 is India's principal anti-graft statute, consolidating laws against bribery by public servants. It defines offences like taking gratification, criminal misconduct and possession of disproportionate assets, and requires prior sanction under Section 19 before prosecuting officials. The CBI and state anti-corruption bureaus investigate under it. Disproportionate-asset cases against public servants are filed under this Act.
• Central Vigilance Commission: The Central Vigilance Commission is India's apex anti-corruption watchdog, created in 1964 on the Santhanam Committee's recommendation and given statutory status by the CVC Act, 2003. It supervises vigilance work in central government organisations, advises on disciplinary cases, and oversees the Chief Vigilance Officers of ministries and public-sector units. It matters for UPSC as a core GS-2 institution on probity, accountability, and governance.
• Customs Act, 1962: The Customs Act, 1962 is the consolidated law governing the levy and collection of customs duties on imports and exports, administered by the Central Board of Indirect Taxes and Customs. It covers prohibition of smuggled goods, warehousing, baggage rules, and adjudication of duty evasion, and operates alongside the Customs Tariff Act, 1975. It is the legal basis of trade regulation questions. Duties on gold imports, a recurring policy tool, are levied under this Act.
• FEO Act 2018: The FEO Act 2018 is the Fugitive Economic Offenders Act, which empowers courts to declare a person a fugitive economic offender and confiscate their properties in India and abroad. It applies where an arrest warrant has been issued, the person has left India to avoid prosecution, and the amount involved is 100 crore rupees or more. It matters for UPSC under economic offences and extradition debates. Example: the 2019 court declaration of Vijay Mallya as a fugitive economic offender. the 2019 court declaration of Vijay Mallya as a fugitive economic offender
