How the CAG Works as India's Audit Institution

The Comptroller and Auditor General of India (CAG) is a constitutional authority established under Articles 148–151 of the Constitution, described by Dr. Ambedkar in the Constituent Assembly as "probably the most important officer under the Constitution" because it is through the CAG that Parliament exercises financial oversight of the executive. 

The CAG serves a six-year term or until age 65, whichever is earlier, is appointed by the President of India, and can be removed only through a parliamentary impeachment process equivalent to removing a Supreme Court judge — constitutional protections designed to ensure independence from executive pressure. The current CAG is K. Sanjay Murthy, a 1989-batch IAS officer who assumed office on November 21, 2024, as the 15th CAG of India.

The CAG's mandate under Articles 148–151 and the Comptroller and Auditor General (Duties, Powers and Conditions of Service) Act, 1971 is comprehensive: to audit all expenditures from the Consolidated Fund of India and state Consolidated Funds; all transactions relating to Contingency Funds and Public Accounts; trading, manufacturing, and profit and loss accounts of government departments; government companies (where the government holds 51% or more equity); and bodies substantially financed from government funds. Three categories of audit reports — on finance, appropriation accounts, and performance — are submitted to the President (for Union accounts) or Governors (for state accounts), tabled before Parliament or state legislatures, and examined by the Public Accounts Committee (PAC) or Committee on Public Undertakings (COPU). CAG audit reports have exposed major governance scandals: the 2G spectrum scam; the Commonwealth Games procurement irregularities; coal block allocation irregularities; and recurring irregularities in public sector procurement, welfare scheme administration, and tax collection.

What You Need to Know

• CAG K. Sanjay Murthy (1989 batch IAS, former Secretary, Department of Higher Education) assumed office November 21, 2024; the preceding CAG Girish Chandra Murmu served 2020–2024; the CAG's salary is charged to the Consolidated Fund, making it immune from parliamentary vote — a constitutional independence protection.
• Drishti IAS (November 2024) documented a concerning trend: the number of CAG audit reports tabled in Parliament declined significantly, from 53 in 2015 to just 18 in 2023 — raising questions about whether the reduced reporting reflects reduced auditing activity, executive pressure on tabling timelines, or organisational capacity constraints.
• The CAG's role in India is that of Auditor General only, not Comptroller: unlike the UK's CAG, which must approve expenditure before it is drawn, India's CAG reviews expenditure after it occurs (ex-post facto); no money can be blocked from being drawn without CAG approval in India, limiting its preventive function.
• The Supreme Court has ruled that the CAG can audit private firms in revenue-share deals with government — extending its mandate to public-private partnership structures that were historically outside its audit perimeter; the CAG is also the external auditor of two UN organisations (FAO and others) and serves on the UN Panel of External Auditors.
• The CAG is the statutory auditor of the Lokpal — India's anti-corruption ombudsman — making it the auditor of India's primary anti-corruption body, an institutional relationship that illustrates the CAG's centrality in India's accountability architecture.

How It Works in Practice

1. Types of audit: The CAG conducts three main audit categories: compliance audits (whether transactions comply with applicable laws and rules); financial audits (whether financial statements present a true and fair picture); and performance audits (whether schemes and programmes are achieving their intended objectives efficiently and effectively). Performance audits — which assess outcomes rather than merely compliance — have been the source of the most politically significant findings, including the 2G spectrum allocation audit and the coal block allocation audit.

2. PAC as the parliamentary link: The Public Accounts Committee of Parliament — conventionally chaired by an opposition party member — examines CAG reports and summoned government officials to explain irregularities. The PAC can call Secretaries of relevant ministries, examine records, and recommend corrective action. Its report to Parliament creates parliamentary pressure for government response. The effectiveness of this mechanism depends on the PAC's willingness to follow through on irregularities and the Parliament's political attention to financial accountability.

3. The ex-post facto limitation: Because India's CAG functions as an Auditor General rather than a Comptroller, it reviews expenditure after funds have been drawn and spent. This means the CAG identifies irregularities that have already occurred rather than preventing them. A CAG audit that identifies ₹100 crore in irregular procurement does not recover that money; it creates a finding that the PAC examines and that the government must respond to; actual recovery or accountability depends on subsequent action by enforcement agencies or courts.

4. State-level accountability: Each state has its office of the Accountant General (AG) — a senior CAG officer who prepares state government audit reports. These are submitted to state Governors and tabled in state legislatures, where state-level PACs examine them. State-level accountability is more variable than central: some states' PACs are active; others are dominated by the ruling party and examine irregularities selectively.

5. Declining report numbers as an accountability concern: The decline from 53 CAG audit reports tabled in Parliament in 2015 to 18 in 2023 is cited by governance analysts as an accountability concern. CAG reports are constitutionally required to be tabled but the timing of tabling is controlled by the executive; delayed tabling means delayed PAC examination; reduced numbers of reports means reduced coverage of government activity. The reasons for the decline have not been officially explained but are a matter of concern to transparency advocates.

What People Often Misunderstand

• The CAG is not an enforcement agency: CAG findings do not automatically result in prosecutions, recoveries, or penalties; they create an audit record that parliamentary committees examine and that can trigger CBI or CVC investigations, but the CAG itself has no enforcement power.
• "CAG report" does not mean the government acted corruptly: CAG audit findings identify irregularities, failures to follow procedure, potential losses to the exchequer, and departures from best practice; not all findings indicate corruption; many reflect administrative failures, unclear procedures, or genuine disputes about proper accounting.
• The CAG's independence is constitutionally protected but not absolute: The CAG cannot be removed casually; but as a retired IAS officer with 35-plus years of government service before appointment, the CAG's independence from the executive is an institutional disposition rather than a physical separation.
• PM CARES Fund audit controversy: The government's refusal to allow CAG audit of the PM CARES Fund (a government-created emergency relief fund for COVID-19) raised questions about the scope of the CAG's audit mandate; the government maintained PM CARES is a public charitable trust, not a government fund; critics argued it was effectively government-controlled and should be subject to CAG audit.
• State-level CAG reports often contain the most consequential findings: Because state governments spend the majority of public money on health, education, and welfare, state-level CAG reports on welfare scheme implementation, public procurement, and fiscal management are often more operationally significant than central government reports.

What Changes Over Time

The Strategic Plan of SAI India 2023–2030 (Strategic Audit Institution of India — the CAG's institutional vision document) sets out priorities including enhanced performance audit, digital audit capabilities, and stronger collaboration with parliamentary committees. 

The Supreme Court's ruling extending CAG audit to private firms in revenue-share arrangements is the most significant recent expansion of the CAG's mandate. The decline in number of reports tabled remains an unresolved transparency concern that civil society organisations and opposition parliamentarians have consistently flagged.

(This series is part of a long-term editorial project to explain the structures, institutions, contradictions, and operating logic of governance in India for a global audience. Designed as a 25-article briefing cluster on Indian Bureaucracy & Administrative Systems, this vertical examines how the administrative machinery of the Indian state functions in practice — from the IAS, ministries, secretaries, district collectors, and government files to procurement, implementation, transfers, accountability mechanisms, inter-ministerial coordination, administrative discretion, and the everyday realities of policy execution. Written in accessible format for diplomats, investors, researchers, NGOs, civil society actors, students, academics, policymakers, and international observers, the series seeks to explain both how India’s administrative system is designed to function on paper and how government decisions are actually made, negotiated, delayed, implemented, and enforced on the ground.
