CAG & public finance accountability

The Office and Its Constitutional Anchor

The Comptroller and Auditor-General of India (CAG) is established by Article 148 of the Constitution. The CAG is appointed by the President under warrant and hand and seal, and can be removed only in the same manner and on the same grounds as a Supreme Court judge (proved misbehaviour or incapacity, by an address of both Houses passed by special majority under Article 124(4)). This security of tenure makes the CAG an independent constitutional functionary, not an executive subordinate. The term is fixed by statute at 6 years or up to age 65, whichever is earlier, under the CAG (Duties, Powers and Conditions of Service) Act, 1971.

Insulation from the Executive

The constitutional design deliberately walls the CAG off from the government it audits. Under Article 148(3) the salary and conditions of service cannot be varied to the CAG's disadvantage after appointment. The administrative expenses of the office, including salaries of the Indian Audit and Accounts Department, are charged on the Consolidated Fund of India (Article 148(6)) and are therefore non-votable in Parliament. On demitting office the CAG is barred from any further office under the Government of India or a State (Article 148(4)) - a bar designed to prevent post-retirement inducements compromising audit independence. Dr B.R. Ambedkar in the Constituent Assembly called the CAG "probably the most important officer in the Constitution of India," ranking the office above even the judiciary in safeguarding the public purse.

The Audit Mandate

Under Article 149 the CAG performs such duties in relation to the accounts of the Union, the States and any other authority as prescribed by law - operationalised through the 1971 Act. The CAG conducts three principal forms of audit:

• Regularity (compliance) audit - whether expenditure conforms to the authority that governs it and to rules and orders.
• Propriety audit - whether spending meets standards of financial prudence and public interest, not merely legal sanction.
• Performance (efficiency) audit - whether programmes achieve their objectives economically, efficiently and effectively (the 3 Es).

The CAG audits all receipts and expenditure from the Consolidated Fund of India and of each State (Article 149), the Contingency Fund and Public Account, and the accounts of government companies and corporations under Sections 19 and 20 of the 1971 Act and Section 143(5) of the Companies Act, 2013. Under Article 150 the CAG advises the President on the form in which Union and State accounts are kept. Under Article 151 the CAG's reports on Union accounts are submitted to the President, who causes them to be laid before each House of Parliament; State reports go to the Governor and the State legislature.

A crucial limitation: the title "Comptroller" is largely nominal. Unlike the British Comptroller and Auditor General, India's CAG has no control over issue of money from the Consolidated Fund - it only audits after expenditure. Reformers have repeatedly urged restoring a genuine comptroller function.

From Audit Report to Accountability: The PAC Link

The CAG is the eyes and ears of Parliament, but the CAG does not itself penalise. The accountability chain runs from audit report to the Public Accounts Committee (PAC) and the Committee on Public Undertakings (COPU). The PAC, traced to the Government of India Act, 1919 and now governed by the Rules of Procedure of the Lok Sabha, has 22 members (15 Lok Sabha, 7 Rajya Sabha) and is by convention chaired by a member of the Opposition - a convention firmly established since 1967. The PAC examines the CAG's reports, summons secretaries as accounting officers, and reports its findings; the CAG assists the PAC as a "friend, philosopher and guide." The PAC scrutinises whether money was spent for the purpose Parliament voted and within the sanctioned amount - it is not concerned with policy merits.

Landmark Reports That Reshaped Public Life

The CAG's authority rests on a record of consequential findings:

• The 2G spectrum report (2010) quantified a notional/presumptive loss of up to Rs 1.76 lakh crore from allocation of 2G licences on a first-come-first-served basis. It triggered the cancellation of 122 licences by the Supreme Court in Centre for Public Interest Litigation v. Union of India (2012) and the holding that natural resources must generally be allocated by auction.
• The coal block allocation report (2012) estimated a presumptive loss of about Rs 1.86 lakh crore, leading to the Supreme Court cancelling 214 coal block allocations in 2014.
• The Bofors and CWG (2010 Commonwealth Games) reports likewise fed parliamentary and prosecutorial scrutiny.

Critiques and the Performance-Audit Turn

The "presumptive loss" methodology drew criticism for assuming counterfactual revenue, and the debate sharpened the distinction between auditing process versus second-guessing policy. The Supreme Court in Association of Unified Telecom Service Providers v. Union of India (2014) affirmed that the CAG can audit the accounts of private telecom licensees because revenue-share is owed to the Consolidated Fund - extending audit reach into public-private contracts. The CAG has since expanded performance audits of flagship schemes (e.g., MGNREGA, PMGSY, Ayushman Bharat), shifting from transaction-checking toward outcome evaluation. The 2017 audit of Ayushman Bharat and audits of GST implementation illustrate this outcome focus. Modern challenges include auditing public-private partnerships, special purpose vehicles, and large welfare DBT flows where money leaves the Consolidated Fund quickly into digital pipelines.

Why This Matters for the Exam

The CAG is a perennial favourite across both Prelims (GS Paper I) and Mains (GS-2), because it sits at the intersection of constitutional bodies, accountability of the executive to the legislature, and public finance - three syllabus headings at once.

How Prelims Tests It

Prelims questions are precise and trap-laden. UPSC has repeatedly probed:

• The exact articles: 148 (appointment/independence), 149 (duties), 150 (form of accounts), 151 (reports). A classic trap pairs the wrong article with the wrong function.
• The distinction between charged and voted expenditure: the CAG's salary is charged on the Consolidated Fund and so is non-votable.
• The removal procedure - same as a Supreme Court judge - and the post-retirement bar (Article 148(4)).
• The fact that the "Comptroller" has no pre-audit/control over withdrawals, unlike the UK model. A 2021-style statement question may ask you to identify which assertions about CAG powers are correct.
• The composition of the PAC (22 members) and the Opposition-chair convention.

Retain these as crisp factual anchors; Prelims rewards exactness, not narrative.

How Mains Tests It

GS-2 ("appointment to various Constitutional posts, powers, functions and responsibilities of various Constitutional Bodies") demands analytical writing. PYQ angles include: "Exercise of CAG's powers in relation to the accounts of the Union and the States is derived from Article 149. Discuss whether audit of the Government Company is necessary" (2021) and questions on the 'friend, philosopher and guide' role of the CAG to the PAC.

A top Mains answer must:

1. Anchor the argument in the constitutional articles and the 1971 Act.
2. Use dated instances - 2G (2010), coal blocks (2012), the 2014 Supreme Court cancellations - as evidence.
3. Engage the presumptive-loss critique and the policy-versus-process line, showing balance.
4. Conclude with reform proposals: a multi-member CAG (as recommended), a genuine comptroller function, and stronger PAC follow-up mechanisms.

High-Yield Takeaways

Independence (Article 148), three audit types (regularity, propriety, performance), the PAC accountability chain, and the limitation that the CAG audits post facto. Link these to current affairs - any recent audit controversy - to show examiners you can apply principle to fact.
