Comptroller and Auditor General of India (CAG) — Articles 148–151

Constitutional Basis

The Comptroller and Auditor General (CAG) of India is established under Article 148 of the Constitution. The CAG is described by Dr. B. R. Ambedkar as the "most important officer in the Constitution of India." It is the Supreme Audit Institution (SAI) of India.

Governing Legislation: The Comptroller and Auditor General's (Duties, Powers and Conditions of Service) Act, 1971 governs the duties and powers in detail.

Appointment and Removal (Article 148)

The salary and service conditions of the CAG are charged upon the Consolidated Fund of India — not subject to Parliamentary vote. This ensures financial independence.

Functions (Article 149 & CAG Act 1971)

The CAG audits the accounts of:

1. Union Government — all receipts and expenditures from the Consolidated Fund of India
2. State Governments — all receipts and expenditures from Consolidated Funds of States
3. Contingency Funds and Public Accounts of Union and States
4. Government companies — under the Companies Act
5. Bodies substantially financed by grants from the Consolidated Fund
6. Autonomous bodies — universities, statutory corporations, as required
7. Panchayati Raj Institutions — where directed by the President or Governor

Key distinction: The CAG audits expenditure already incurred; it does not have pre-audit or comptroller functions in respect of Union expenditure (this function was separated in practice — the CAG acts as an auditor, not a comptroller, for Union government).

Types of Audit Conducted by CAG

1. Compliance Audit (Regularity and Propriety Audit)

Examines whether government transactions comply with the Constitution, Acts, laws, rules, regulations, budgetary provisions, and sanctions. Checks:

• Whether spending was authorised and properly accounted for
• Whether financial rules and procedures were followed

2. Performance Audit

Evaluates whether government programmes and schemes are being implemented with economy, efficiency, and effectiveness (the "3 Es"). Answers:

• Was money spent economically?
• Was the programme efficiently executed?
• Were the intended outcomes (effectiveness) achieved?

3. Propriety Audit (Value-for-Money Audit)

A discretionary audit that examines the wisdom, faithfulness, and economy of government expenditure. Goes beyond legality to check:

• Whether expenditure is extravagant or wasteful
• Whether public money was spent with the same prudence a person would apply to their own money

4. Financial Audit

Certification of government accounts and financial statements — ensuring accounts reflect a true and fair view.

Reports to Parliament (Article 151)

The CAG submits audit reports to the President, who causes them to be laid before each House of Parliament. For States, reports go to the Governor, who places them before the State Legislature.

Three main reports to Parliament:

These reports are then examined by:

• Public Accounts Committee (PAC) of Parliament — examines CAG's audit report on government expenditure
• Committee on Public Undertakings (COPU) — examines CAG reports on government companies

CAG as Guardian of Public Finances

The CAG plays a crucial watchdog role in the Indian parliamentary democracy:

• Acts as the "sentinel of the public purse"
• Ensures accountability of the executive to the legislature
• Provides independent assurance to Parliament that public money was spent as authorised

Key limitation: CAG cannot disallow expenditure or recover money — it can only report irregularities. Executive action follows based on Parliamentary committee recommendations.

Relationship with Parliamentary Committees

Recent Developments (2024–2026)

New CAG — K. Sanjay Murthy Assumes Office (November 2024)

K. Sanjay Murthy (IAS, 1989 batch) was sworn in as the 15th Comptroller and Auditor General of India on 21 November 2024 by President Droupadi Murmu at Rashtrapati Bhavan. He succeeds Girish Chandra Murmu (who served from August 2020 to November 2024). Murthy previously served as Secretary, Department of Higher Education (Ministry of Education) and CEO of the National Industrial Corridor Development Corporation Limited (NICDC) under the Ministry of Commerce.

The CAG holds office for a term of 6 years or until age 65, whichever is earlier, and is not eligible for reappointment. Salary is charged to the Consolidated Fund of India.

UPSC angle: Prelims — K. Sanjay Murthy, 15th CAG; sworn in 21 November 2024; 1989 batch IAS; Article 148; 6 years or age 65. Mains — evaluate the CAG's role as Parliament's watchdog; is the current constitutional framework adequate to ensure the CAG's independence from the executive?

CAG Report on FRBM Compliance — Fiscal Deficit Audit (2024)

The CAG issued a performance audit report (Report No. 1 of 2024) on the Union Government's compliance with the Fiscal Responsibility and Budget Management (FRBM) Act, 2003 for the year 2021-22. The report examined the fiscal deficit, public debt trajectory, and accounting practices for grants and loans to ascertain compliance with FRBM targets. The report is placed before Parliament under Article 151 and examined by the Public Accounts Committee.

CAG reports on FRBM compliance are directly relevant to fiscal accountability and parliamentary oversight of government finances — a recurring GS2 theme.

UPSC angle: Prelims — Article 151 (CAG reports to Parliament); PAC examines CAG reports; Report No. 1 of 2024 on FRBM. Mains — critically examine the CAG's audit function in fiscal accountability; evaluate the effectiveness of PAC scrutiny of CAG reports.

CAG's Performance Audit on Smart Cities and PM Gati Shakti (2024–2025)

The CAG conducted performance audits on the Smart Cities Mission and PM Gati Shakti infrastructure programme in 2024–2025. Key findings included: delays in project completion, fund underutilisation in certain smart cities, lack of outcome indicators for measuring liveability improvements, and gaps in Integrated Command and Control Centre (ICCC) data quality.

CAG reports on flagship schemes directly feed into Parliamentary Committee scrutiny and inform public discourse on governance accountability — the classic intersection of Article 148 (CAG) and Article 118 (Parliamentary procedures).

UPSC angle: Prelims — CAG performance audit under DPC Act 1971 (Section 16); Reports to Parliament under Article 151. Mains — examine how CAG performance audits contribute to accountability of welfare schemes; assess whether the current framework is adequate for auditing digital infrastructure projects.

Exam Relevance

Prelims traps:

• CAG's tenure: 6 years or 65 years, whichever earlier — not reappointable
• Removal: same process as Supreme Court judge (special majority in both Houses)
• CAG's expenses charged on Consolidated Fund of India — not votable
• Article 150: Form of accounts on advice of CAG — not at CAG's discretion, but the President acts on CAG's advice
• CAG audits both Union and State accounts

Mains angles:

• CAG's role in strengthening legislative oversight and executive accountability
• Limitations: no pre-audit power over Union; reports come after expenditure; government not bound to act on CAG findings
• Significance of CAG reports in exposing major scams (2G spectrum, Commonwealth Games, coal block allocation)
• Debate on CAG's jurisdiction over PPP projects, private entities receiving government grants
