Constitution of India
Article 148: Comptroller and Auditor-General of India
Part V — The Union (Chapter V — Comptroller and Auditor-General of India)
Clause (1)
WHAT IT SAYS: There shall be a CAG of India, appointed by the President by warrant under his hand and seal, removable only in like manner and on like grounds as a Supreme Court Judge. WHAT IT MEANS: Establishes the office constitutionally; appointment is formal and solemn; removal requires parliamentary impeachment (proved misbehaviour or incapacity + special majority in both Houses), ensuring security of tenure. KEY DOCTRINE: Doctrine of Constitutional Independence — the CAG is insulated from executive pressure through the same removal safeguard as SC Judges (Article 124(4)).
Clause (2)
WHAT IT SAYS: Before entering office, the CAG shall make and subscribe before the President an oath or affirmation in the form set out in the Third Schedule. WHAT IT MEANS: The oath binds the CAG to uphold the Constitution and discharge duties without fear, favour, affection, or ill-will — a constitutional formality underlining impartiality. KEY DOCTRINE: Oath of Office Requirement — symbolises constitutional commitment to neutrality and integrity before assuming a constitutional office.
Clause (3)
WHAT IT SAYS: Salary and conditions of service of the CAG shall be determined by Parliament by law; until so determined, as specified in the Second Schedule. Proviso: salary, leave, pension, and retirement age shall not be varied to his disadvantage after appointment. WHAT IT MEANS: Parliament controls the CAG's service conditions, but the proviso creates a constitutional lock against executive retaliation — once appointed, terms cannot be worsened. KEY DOCTRINE: Non-Diminution of Service Conditions — a constitutional guarantee protecting the incumbent from financial pressure by the executive.
Clause (4)
WHAT IT SAYS: The CAG shall not be eligible for further office either under the Government of India or under the Government of any State after ceasing to hold office. WHAT IT MEANS: An absolute bar on post-retirement government employment — prevents the executive from offering lucrative posts as inducement for favourable audits. KEY DOCTRINE: Post-Retirement Bar / Cooling-Off Principle — ensures absolute neutrality and non-partisanship during tenure by removing all post-office incentives.
Clause (5)
WHAT IT SAYS: Conditions of service of persons in the Indian Audit and Accounts Department and the administrative powers of the CAG shall be prescribed by rules made by the President after consultation with the CAG. WHAT IT MEANS: The IA&AD staff serve under rules made by the President, but only after consulting the CAG — preserving functional autonomy of the CAG's department while maintaining coordination with the executive. KEY DOCTRINE: Mandatory Consultation — the President must consult the CAG, ensuring the audit apparatus remains functionally autonomous from executive control.
Clause (6)
WHAT IT SAYS: Administrative expenses of the CAG's office — including all salaries, allowances, and pensions — shall be charged upon the Consolidated Fund of India. WHAT IT MEANS: These expenses are 'charged' (not 'voted'), meaning Parliament cannot refuse to pay them — the CAG's office cannot be financially starved by the executive or legislature. KEY DOCTRINE: Charged Expenditure Principle — expenses charged on the Consolidated Fund are non-votable, guaranteeing financial independence of constitutional functionaries.
Constitutional Inspiration
SOURCE(S): 1. United Kingdom — Exchequer and Audit Departments Act, 1866 (Comptroller and Auditor General of the UK) Original provision: Created the UK CAG to audit public expenditure and exercise comptroller functions over the issue of money from the Exchequer, reporting to Parliament. What India kept: The concept of an independent constitutional auditor reporting to the legislature, with security of tenure and financial independence. 2. Government of India Act, 1935 — Section 166 (Auditor General of India) Original provision: Section 166 provided for an Auditor General appointed by the Crown, with independence and audit powers over Dominion and Provincial accounts. What India kept: The structural framework of an independent auditor was retained and strengthened with constitutional status, formal oath, and charged expenditure. INDIA'S SPECIFIC ADAPTATIONS: 1. Title changed from 'Auditor-General' to 'Comptroller and Auditor-General' — T.T. Krishnamachari argued the title should reflect both audit and comptroller functions over government expenditure. 2. In practice, the Indian CAG functions only as Auditor General (post-facto audit), unlike the UK CAG who controls issue of money from the Exchequer — India did not operationalise the comptroller function. 3. Single CAG for both Union and States — unlike a federal model with separate state auditors, India chose a unified audit authority to ensure uniformity and strength of audit across the federation. 4. Absolute post-retirement bar on government employment (Clause 4) — more restrictive than the UK model, to prevent executive inducement in a developing democracy. 5. Appointment by 'warrant under hand and seal' was an Indian Constituent Assembly addition to bring parity with the Chief Justice's appointment under Article 124.
Constituent Assembly Debate
DEBATED ON: 30 May 1949 (CAD Volume VIII) Also revisited on: 16 November 1949 (CAD Volume XI — consequential/drafting amendments) DRAFT ARTICLE: Draft Article 124 KEY SPEAKERS: 1. T.T. Krishnamachari (Drafting Committee) — Proposed renaming 'Auditor-General' to 'Comptroller and Auditor-General' to reflect both audit and expenditure control functions; also proposed charging administrative expenses to the Consolidated Fund and aligning staff service conditions with Supreme Court parity. 2. H.N. Kunzru — Proposed appointment 'by warrant under hand and seal' to match the CJI appointment language under Draft Article 103 (Article 124); this was accepted. 3. Biswanath Das — Strongly opposed charging CAG expenses to revenue, arguing that Parliament should retain the right to vote on the CAG's budget and not perpetuate colonial-era practices from the 1935 Act. 4. K.T. Shah — Argued for giving the CAG fullest power and constitutional protection so that no one could interfere with the audit function; wanted the Constitution to explicitly bar expenditure beyond budget grants. 5. P.S. Deshmukh — Participated in the debate on the scope and independence of the Auditor-General. MAJOR DISAGREEMENTS: 1. Whether administrative expenses should be 'charged' on revenue — Biswanath Das opposed this; majority supported it as necessary to prevent executive pressure on the CAG. 2. Whether the CAG should have a separate Auditor-General for each State — This was debated but the Assembly decided on a single CAG for both Union and States. 3. Whether the CAG should have explicit constitutional power to prevent excess expenditure beyond Appropriation Act — K.T. Shah proposed this; Ambedkar declined, calling it a fundamental understood principle not needing constitutional mention. FINAL OUTCOME: All amendments by T.T. Krishnamachari and H.N. Kunzru were accepted; Biswanath Das's objection to charged expenditure was rejected; K.T. Shah's proposal for explicit excess-expenditure bar was not adopted. AMBEDKAR'S KEY QUOTE: "I am of opinion that this dignitary or officer is probably the most important officer in the Constitution of India. He is the one man who is going to see that the expenses voted by Parliament are not exceeded."
Landmark Judgments
LANDMARK JUDGMENTS: 1. K.S. Venkataraman v. Union of India (1954) — The Supreme Court affirmed that the CAG is an independent constitutional authority, free from executive control and accountable only to the Constitution. 2. S. Subramaniam Balaji v. State of Tamil Nadu (2013) — The Court held that Article 148 creates a constitutional functionary in the CAG whose main role is to audit income and expenditure of governments, with duties listed in the 1971 Act. 3. Arvind Gupta v. Union of India (2013) — The Supreme Court upheld the CAG's authority to conduct performance audits in addition to financial audits, broadening the scope of CAG's audit jurisdiction. 4. Arun Kumar Aggarwal v. Union of India (2013) — The Court clarified that a CAG audit report cannot be directly accepted by the Court to grant relief; it is subject to scrutiny by Parliament. 5. Comptroller and Auditor General of India v. Union of India (2018) — The Court reaffirmed the CAG's power to audit non-governmental entities receiving substantial public funds. 6. State of Uttar Pradesh v. Rajendra Singh (2009) — The Supreme Court clarified that the CAG's audit jurisdiction extends to examination of financial transactions by State authorities. NOTABLE OBSERVATIONS (Bombay High Court): 1. Reghu Nath Kelkar v. Union of India (2009) — The Bombay HC held that the time, scope, and extent of audit fall within the exclusive jurisdiction of the CAG and courts should not tread on this domain. SCHOLARS & JURISTS: 1. Dr. B.R. Ambedkar — Called the CAG 'probably the most important officer in the Constitution of India,' whose duties are 'far more important than the duties even of the Judiciary.' 2. Justice M.N. Venkatachaliah (NCRWC, 2002) — Recommended constituting a multi-member Audit Commission to replace the single-person CAG office for better institutional capacity. 3. Vinod Rai (Former CAG) — Advocated bringing PPPs, Panchayati Raj Institutions, and government-funded societies within CAG's audit ambit; recommended amending the 1971 Act and collegium-type mechanism for CAG appointment.
