Discuss the institutional relationship between the CVC and CBI in tackling corruption in India. What are the structural constraints limiting their effectiveness?

The Central Vigilance Commission (CVC), statutory since the CVC Act, 2003 [2], is India's apex integrity watchdog, while the Central Bureau of Investigation (CBI), raised under the Delhi Special Police Establishment (DSPE) Act, 1946 [3], is the executive arm that investigates offences under the Prevention of Corruption (PC) Act, 1988. Their relationship is legally interlocked but institutionally uneven.

Institutional relationship: complementary roles

• Superintendence: the CVC Act vests in the Commission superintendence over the CBI's investigation of PC Act offences, making CVC the supervisory conscience of the agency [2].
• Personnel insulation: a CVC-headed committee recommends CBI appointments at senior levels under the DSPE Act, a safeguard traceable to the Vineet Narain (1997) directions [3][6].
• Division of labour: CBI registers, investigates and prosecutes; CVC tenders advice on departmental action through Chief Vigilance Officers — 1,460 departmental inquiries were pending in 2025 [1].
• Accountability: CVC's Annual Report is the principal public audit of anti-corruption performance, recording a 71.71% conviction rate in 2025 [1].

Structural constraints

• No investigative machinery of its own; CVC's advice is recommendatory, leaving enforcement dependent on the CBI.
• Capacity deficit: 1,088 vacancies against a sanctioned strength of 7,300, mostly executive ranks; 274 regular cases lay under investigation beyond a year [1].
• Judicial bottleneck: 7,229 PC Act cases pending trial, 409 for over two decades, and 14,083 appeals clogging constitutional courts [1].
• Procedural brakes: prior approval under Section 17A (2018 amendment) and sanction requirements delay initiation [4]; CBI's entry into states depends on consent under Section 6, DSPE Act [3].

Effectiveness therefore falters less in law than in institutional capacity. Acting on the Second ARC's Ethics in Governance prescription — dedicated anti-corruption courts, time-bound trials and insulated agency leadership [5] — alongside filling vacancies, would convert supervisory architecture into genuine deterrence, advancing probity as a constitutional value.
