CAG — Powers and Functions

Introduction

The:

Comptroller and Auditor General of India (CAG)

is a:

Constitutional Authority

whose principal powers and functions arise from:

Articles 148–151

and the:

CAG's Duties, Powers and Conditions of Service Act, 1971

The CAG's central role is:

Audit + Report + Financial Accountability

It helps Parliament and State Legislatures exercise:

Control Over Public Finances

Core Principle

CAG Audits Government Finances and Reports Irregularities; It Does Not Run the Government or Prosecute Officials.


1. Constitutional Basis of CAG Powers

The key Articles are:

Article 148
→ Office and Independence of CAG

Article 149
→ Duties and Powers

Article 150
→ Form of Accounts

Article 151
→ Audit Reports

Memory

148 → Office

149 → Powers

150 → Accounts

151 → Reports


2. Article 149 — Main Source of Powers

Article 149 provides that the:

Duties and Powers of the CAG

are prescribed by:

Parliament by Law

The principal law is:

CAG's Duties, Powers and Conditions of Service Act, 1971

Thus:

Article 149 + CAG Act 1971 = Detailed Audit Powers


3. Audit of Union Government Accounts

The CAG audits:

Accounts of the Union Government

This includes examination of:

  • Government expenditure
  • Government receipts
  • Appropriations
  • Financial transactions
  • Public funds

The objective is:

Financial Accountability of the Union Executive to Parliament


4. Audit of State Government Accounts

The CAG also audits:

Accounts of State Governments

This ensures accountability to:

State Legislatures

Thus:

CAG
→ Union Finances
→ State Finances

Federal Significance

One Constitutional Audit Institution Covers Both Levels of Government.


5. Audit of Expenditure

One of the most important CAG functions is:

Audit of Government Expenditure

The CAG examines whether expenditure was:

  • Legally authorised
  • Properly classified
  • Correctly accounted for
  • Used for the intended purpose
  • Consistent with applicable rules

6. Appropriation Audit

Appropriation Audit

examines whether money was spent:

Within the Authority Granted by Parliament or State Legislature

Key Question

Was Public Money Spent for the Purpose and Within the Limits Authorised by the Legislature?

Memory

Appropriation Audit → Legislative Authorisation


7. Audit of Receipts

The CAG audits:

Government Receipts

including:

  • Tax revenue
  • Non-tax revenue
  • Government dues
  • Other public receipts

The objective is to determine whether:

Revenue Was Properly Assessed, Collected and Accounted For


8. Revenue Audit

Revenue audit examines:

  • Assessment of government revenue
  • Collection of dues
  • Revenue leakage
  • Short-levy
  • Non-realisation of government dues

Principle

CAG Watches Both the Spending Side and the Revenue Side of Public Finance.


9. Audit of Consolidated Fund

The CAG audits transactions involving:

Consolidated Fund of India

and:

Consolidated Funds of States

This is important because expenditure from the Consolidated Fund requires:

Legislative Authorisation

subject to constitutional exceptions.


10. Audit of Contingency Fund

The CAG audits transactions relating to:

Contingency Funds

within the applicable constitutional and statutory framework.

The purpose is to ensure:

Proper Financial Reporting + Accountability


11. Audit of Public Account

The CAG also audits transactions relating to:

Public Account

The objective is:

Proper Accounting + Lawful Financial Administration

of funds held by government in its public-account capacity.


12. Audit of Grants and Loans

The CAG can audit certain:

Grants and Loans

given from public funds.

This can include scrutiny of:

  • Utilisation
  • Compliance with conditions
  • Financial records
  • Public accountability

13. Audit of Bodies and Authorities Receiving Public Money

Certain bodies or authorities receiving:

Substantial Grants or Loans

from public funds may come under CAG audit subject to:

Statutory Conditions

The legal basis is important.

Trap

Every organisation receiving any government money is automatically audited by CAG.

False.


14. Audit of Government Companies

The CAG has statutory audit responsibilities relating to:

Government Companies

under the applicable:

Companies Law + CAG Framework

The CAG's role may include:

  • Supplementary audit
  • Comments on accounts
  • Directions concerning audit
  • Examination of financial statements

15. Audit of Government Corporations

The CAG may audit:

Government Corporations

where the:

Relevant Statute

provides for CAG audit.

Important

CAG audit is not automatically applicable merely because:

Government Has Some Ownership Interest

There must be:

Legal Authority


16. Audit of Public Sector Enterprises

CAG contributes to financial accountability of:

Public Sector Enterprises

through the audit mechanisms available under:

  • Companies law
  • Sector-specific statutes
  • CAG Act
  • Other applicable laws

17. Audit of Autonomous Bodies

Certain:

Autonomous Bodies

may be audited by the CAG where the required:

Constitutional / Statutory Conditions

are satisfied.

The key principle is:

CAG Jurisdiction Depends on Legal Authority, Not Merely Government Association.


18. Performance Audit

Performance Audit

examines whether government programmes or activities achieve:

Economy + Efficiency + Effectiveness

Memory

EEE

Questions Asked

Economy → Were resources obtained economically?

Efficiency → Were resources used efficiently?

Effectiveness → Were intended outcomes achieved?


19. Compliance Audit

Compliance Audit

examines whether government actions comply with:

  • Laws
  • Rules
  • Regulations
  • Orders
  • Procedures

Example

Expenditure without required:

Sanction

may indicate a compliance issue.


20. Financial Audit

Financial Audit

examines:

Financial Statements + Accounts

and whether they are prepared and presented according to the applicable financial framework.


21. Propriety Audit

Propriety Audit

goes beyond mere legality.

It examines whether expenditure was:

  • Prudent
  • Justified
  • In public interest
  • Consistent with accepted financial standards

Key Distinction

Compliance → Is It Legal / Rule-Compliant?

Propriety → Was It Financially Prudent and Justifiable?


22. Audit of Public Expenditure

The CAG may identify:

  • Wasteful expenditure
  • Avoidable expenditure
  • Irregular expenditure
  • Unauthorised expenditure
  • Weak financial controls
  • Mismanagement

This helps strengthen:

Public Financial Management


23. Access to Records

For effective audit, the CAG has statutory authority to obtain:

Information + Documents + Records

necessary for carrying out audit functions.

This is essential because:

Audit Without Access to Records Is Ineffective.


24. Examination of Government Records

The CAG's audit machinery may examine:

  • Files
  • Registers
  • Accounts
  • Vouchers
  • Contracts
  • Financial statements
  • Other relevant records

subject to the applicable legal framework.


25. Calling for Information

Government departments and audited entities must provide:

Necessary Information

for the performance of CAG audit functions.

This ensures:

Effective Financial Scrutiny


26. Audit of Transactions

The CAG examines government transactions to determine whether they are:

  • Properly authorised
  • Correctly recorded
  • Consistent with law
  • Financially prudent
  • Properly implemented

27. Audit Reports

After audit, the CAG prepares:

Audit Reports

These may identify:

  • Poor implementation
  • Inefficiency
  • Weak internal controls
  • Governance failures

28. Article 151 — Union Reports

CAG reports relating to the:

Union Government

are submitted to the:

President

The President causes them to be laid before:

Both Houses of Parliament

Memory

Union → President → Parliament


29. Article 151 — State Reports

CAG reports relating to a:

State Government

are submitted to the:

Governor

The Governor causes them to be laid before:

State Legislature

Memory

State → Governor → Legislature


30. CAG and Public Accounts Committee

The:

Public Accounts Committee (PAC)

examines CAG reports.

Therefore:

CAG
→ Audits

CAG
→ Reports

PAC
→ Scrutinises

Legislature
→ Holds Executive Accountable

Golden Line

CAG Audits; PAC Examines.


31. CAG as "Watchdog of Public Purse"

The CAG is often described as:

Watchdog of the Public Purse

because it helps Parliament and State Legislatures monitor:

How Public Money Is Raised, Authorised and Spent

However, it is not:

A Police Agency

or:

A Prosecuting Authority


32. CAG Does Not Punish Officials

The CAG can:

Identify + Report

irregularities.

It does not normally:

  • Arrest officials
  • Prosecute officials
  • Impose criminal punishment

Follow-up action may involve:

  • Departmental authorities
  • Investigative agencies
  • Vigilance bodies
  • Courts
  • Legislatures

33. CAG vs Investigative Agencies

CAG

Audit + Report

CBI / Police

Investigation + Prosecution

CVC

Vigilance Oversight

PAC

Legislative Scrutiny

Memory

Audit → Investigation → Vigilance → Accountability


34. CAG and Policy Decisions

The CAG can examine:

Financial Consequences + Implementation + Compliance + Performance

of government policies.

However:

CAG Is Not a Parallel Policy-Making Authority

It should not replace the:

Executive's Legitimate Policy Choice


35. Audit vs Policy

A common constitutional issue is:

How Far Can Performance Audit Go Into Policy?

The CAG may assess:

  • Economy
  • Efficiency
  • Effectiveness
  • Implementation

But policy decisions that are:

Lawful + Constitutionally Valid

remain primarily within:

Political Executive Authority


36. CAG and Financial Accountability

The CAG strengthens:

Legislative Financial Control

because governments spend public money that is ultimately subject to:

Legislative Authorisation + Public Accountability


37. CAG and Fiscal Federalism

The CAG audits:

Union + State Finances

Therefore it contributes to:

Fiscal Accountability Across Federal Levels


38. CAG and Transparency

CAG reports contribute to:

Public Transparency

by bringing important financial findings into the:

Legislative Accountability Process


39. CAG and Governance

CAG audits can reveal:

  • Weak procurement
  • Revenue leakage
  • Ineffective schemes
  • Cost overruns
  • Delayed projects
  • Poor internal controls

Thus audit can support:

Better Governance + Better Public Expenditure


40. CAG and Outcome-Based Governance

Performance audit increasingly connects:

Public Spending

with:

Actual Outcomes

This shifts accountability from:

Money Spent

to:

Value and Results Achieved


41. CAG and Public Procurement

The CAG may examine procurement transactions for:

  • Compliance with rules
  • Transparency
  • Competition
  • Financial prudence
  • Value for money

This can help identify:

Procurement Irregularities


42. CAG and Natural Resources

CAG audits can examine management of:

  • Spectrum
  • Minerals
  • Coal
  • Land
  • Other public resources

The central principle is:

Public Resources Must Be Managed in Accordance With Law and Public Interest.


43. CAG and Public Resource Allocation

CAG reports can bring attention to:

  • Revenue implications
  • Allocation procedures
  • Transparency
  • Financial consequences

However the CAG's role remains:

Audit + Reporting

rather than:

Policy Formulation


44. CAG and Grants to NGOs / Institutions

Where grants or loans from public funds fall within the statutory audit framework, the CAG may examine:

  • Utilisation
  • Compliance
  • Financial records
  • Intended purpose

This supports:

Accountability for Public Money Beyond Government Departments


45. CAG and Modern Auditing

Modern auditing may involve:

  • Data analytics
  • Digital records
  • IT systems
  • Technology-enabled financial scrutiny
  • Outcome measurement

This strengthens:

Evidence-Based Public Financial Accountability


46. CAG and Confidential Information

Audit access can involve sensitive government information.

The audit process therefore operates within:

Legal + Constitutional + Confidentiality Requirements

CAG access does not mean:

Unlimited Public Disclosure of Every Confidential Government Record


47. Independence and Powers

CAG's ability to exercise powers effectively depends on:

  • Secure tenure
  • Removal safeguards
  • Financial independence
  • Administrative autonomy
  • Access to records
  • Constitutional status

Thus:

Independence + Powers = Effective Audit


48. Important Distinction — Constitutional vs Statutory Powers

Constitution

Articles 148–151

provide:

Institution + Framework

Parliament

through:

CAG Act, 1971

provides:

Detailed Duties + Powers

Memory

Constitution Creates → Parliament Details


49. Limits of CAG Powers

The CAG does not have:

Unlimited Audit Authority

Its powers are subject to:

  • Constitution
  • CAG Act
  • Other applicable laws
  • Scope of statutory audit jurisdiction
  • Judicial review

50. CAG and Judicial Review

CAG actions may be subject to:

Judicial Review

where questions arise regarding:

  • Jurisdiction
  • Statutory authority
  • Constitutional limits
  • Procedural fairness
  • Abuse of power

This ensures:

Audit Authority Remains Constitutionally Bounded
