CAG of India: Role, Powers & Constitutional Provisions

TL;DR Summary:

CAG stands for Comptroller and Auditor General of India, the country’s supreme audit authority. Established under Article 148 of the Constitution; reports to Parliament, not the executive. Appointed by the President; serves 6 years or until age 65, whichever is earlier. Audits all Union and state government expenditure, PSUs, and government-funded bodies. Conducts five types of audits: financial, compliance, performance, propriety, and IT. Submits reports to Parliament via the President; state reports go through the Governor. The Public Accounts Committee examines CAG findings and holds ministries accountable. It cannot arrest, prosecute, or issue binding orders, audit, and report is its mandate. Notable reports include 2G spectrum, Coalgate, and Commonwealth Games irregularities. All CAG reports are publicly available at cag.gov.in

The role of CAG of India is to independently audit how the Union and state governments spend public money: every rupee, every scheme, every public sector company.

This article explains the role of comptroller and auditor general of India, what it audits, how it operates, and why every taxpayer should know it exists.

What Is the CAG of India? — Full Form & Overview

CAG or Comptroller and Auditor General of India is the country’s supreme audit institution.

It is a constitutional authority that looks at how the central and state governments earn money and spend it. The CAG then reports whether that money was used legally, wisely, and for the purpose intended.

The role of CAG of India is unique. No other country gives its auditor such wide authority over both the Comptroller (someone who controls government accounts) and the Auditor General functions.

Here’s what the CAG actually does:

Examines government accounts: Every rupee collected as tax, fee, or revenue.
Checks spending: From building highways to buying office chairs for ministries.
Audits public sector companies: Railways, defence, public sector banks, and government-run corporations.
Reports directly to Parliament: No minister can stop or change a CAG report.

Every rupee routed through the Consolidated Fund of India: the central pool that receives all government revenues and from which all expenditures are authorised: falls within the CAG’s audit jurisdiction. So does money from the Contingency Fund and the Public Account of India. For state governments, the equivalent state funds are covered as well.

The CAG heads the Indian Audit and Accounts Department (IA&AD), which employs people across field audit offices throughout the country.

Beyond auditing, the CAG also maintains accounts for state governments (in states that have not set up a separate accountant general arrangement) and certifies the annual accounts of government entities. It also advises on the form in which public accounts should be structured.

However, the CAG is not a vigilance or anti-corruption body. It does not file FIRs, conduct raids, or prosecute officials. Its job is to audit, compile findings, and present them to Parliament or the state legislature.

What happens after that depends on the legislature and the executive.

Constitutional Basis — Articles 148 to 151 Explained

The CAG does not work under the government. It is a constitutional authority that works for Parliament.

The CAG’s office, independence, and core powers are embedded in the Constitution and cannot be altered without a constitutional amendment.

Four articles, 148 to 151, create the legal backbone for the role of CAG of India. These provisions were designed to make the office independent.

Article	Focus	Key Feature
148	Office & independence	Removal like Supreme Court judge
149	Duties & powers	Parliament prescribes by law
150	Form of accounts	President acts on CAG’s advice
151	Audit reports	Mandatory submission to legislatures

Article 148: The Office of CAG

This is the founding article that establishes the office.

It states that there shall be a Comptroller and Auditor General of India, appointed by the President.

It lays down conditions of service and protects the independence of the office.

Once appointed, the CAG cannot be removed except through an address passed by both Houses of Parliament, on grounds of proved misbehaviour or incapacity. The removal process is similar to that of a Supreme Court judge.

Removal requires proven misbehaviour or incapacity, established through an impeachment process in Parliament.

Article 148(4) adds another layer. After retiring, the CAG cannot hold any government office: neither central nor state. This removes any temptation. No future job means no pressure to please the government while serving as CAG.

The article also says the administrative expenses of the CAG’s office are charged on the Consolidated Fund of India. That means, the government cannot cut the CAG’s budget to punish a critical report. The money is automatically available.

Article 149: Duties and Powers

Article 149 tells you what the CAG does. It empowers Parliament to prescribe the duties and powers of the CAG over the accounts of the Union and the states.

The CAG’s (Duties, Powers and Conditions of Service) Act, 1971 was enacted under this article. That Act gives the CAG authority to audit the Union, states, and any other body receiving government funds.

Article 150: Form of Accounts

Article 150 decides how government accounts are kept. It requires that the accounts of the Union and each state be maintained in the form the President prescribes, on the advice of the CAG.

This means the CAG’s advice shapes how every rupee is recorded. No uniform accounting standard exists without the CAG’s input.

Article 151: Audit Reports

Article 151 mandates where CAG’s audit reports should be submitted.

For Union accounts, the CAG submits reports to the President. The President then causes them to be laid before each House of Parliament.

For state accounts, the reports go to the Governor, who lays them before the state legislature.

No minister can stop a report. No bureaucrat can delay it. The Constitution forces the executive to place these reports before the people’s elected representatives. That is accountability built into the system.

Together, these four articles give the CAG three distinct roles:

Auditor: independent examination of government accounts and transactions
Accountant: maintaining accounts for state governments
Advisor: guiding the structure and format of public financial records

The constitutional design places the CAG outside the executive branch on purpose.

The office reports to Parliament, not to the Finance Ministry or the Cabinet. That ensures credibility and independence.

Appointment, Tenure & Removal of the CAG

Here’s a quick overview, before we get to the details:

Feature	Protection Offered
Appointment	President appoints based on PM’s recommendation (current practice)
Tenure	6 years or age 65, fixed, not year-to-year
Removal	Same process as Supreme Court judge — special majority in both Houses
Post-retirement job ban	Cannot take any government office
Salary protection	Cannot be reduced after appointment
Budget protection	Office expenses charged on Consolidated Fund, no annual vote

The President of India appoints the CAG. The President does this by a warrant under hand and seal.

That is a formal written order with the President’s signature. You do not need a separate election or parliamentary vote to appoint the CAG.

But here is the practical reality:

The President acts on aid and advice of the Council of Ministers. The actual process starts with the Cabinet Secretary preparing a shortlist. The Finance Minister approves the shortlist.

Then the Prime Minister recommends a name to the President. The person must also take an oath or affirmation before the President, swearing to uphold the Constitution and perform duties impartially.

Qualifications:

The Constitution does not prescribe any qualifications for the CAG. Neither Article 148 nor the CAG’s (Duties, Powers and Conditions of Service) Act, 1971, sets down any minimum educational, professional, or experience criteria.

In 2025, the Supreme Court heard a PIL arguing that the current executive-only method violates the Constitution. But as of now, the executive remains firmly in control of selection.

Tenure:

The CAG holds office for a fixed period: six years or until reaching the age of 65 years, whichever happens earlier.

For example, if a person is appointed at age 60, they serve only for five years (until turning 65).

The six-year term gives enough time for the CAG to initiate and complete major audit reports without facing year-to-year renewal pressure.

Resignation:

The CAG can also resign before completing the term. The resignation letter goes to the President.

Removal:

This is where the constitutional protection becomes significant.

Here is the step-by-step removal process:

A resolution for removal must be passed by both Houses of Parliament: Lok Sabha and Rajya Sabha.
The resolution requires a special majority: a majority of the total membership of that House AND a majority of not less than two-thirds of members present and voting.
The ground for removal must be proved misbehaviour or incapacity. Mere disagreement with reports or policy is not enough.
The President issues the removal order only after such a resolution is passed.

This makes arbitrary dismissal extremely difficult. A government dissatisfied with an uncomfortable audit finding cannot simply remove the CAG.

Post-retirement bar:

Once out of office, the CAG is not eligible for any further appointment under the Government of India or any state government.

This eliminates the possibility of the CAG moderating findings in anticipation of a post-retirement role. It is a meaningful conflict-of-interest safeguard.

Salary:

The CAG’s salary is charged directly to the Consolidated Fund of India. It is not subject to a Parliamentary vote. Parliament cannot reduce the CAG’s salary as a pressure tactic.

The salary is equivalent to that of a Supreme Court judge, which places the office firmly among the top constitutional functionaries in the country.

Powers of the CAG — What Can It Audit?

Under the CAG’s (Duties, Powers and Conditions of Service) Act, 1971, the CAG’s audit jurisdiction covers:

Union Government: All receipts and expenditure from the Consolidated Fund of India, the Contingency Fund, and the Public Account of India.

State Governments: The corresponding funds of each state , the Consolidated Fund, the Contingency Fund, and the State Public Account.

Government Companies: Under Section 619 of the Companies Act, the CAG is the primary auditor for companies where the central or state government holds more than 51% equity. The CAG appoints the statutory auditor (typically a CA firm) for such companies and conducts a supplementary audit of their financial statements.

Autonomous Bodies and Grantee Institutions: Bodies substantially funded by the government such as universities, research institutions, and registered societies receiving grants are subject to CAG audit when their government funding exceeds specified thresholds.

Central and State PSUs: Both central public sector undertakings and state PSUs fall within the CAG’s scope.

Local Bodies: In many states, the CAG also audits panchayats and urban local bodies, particularly where significant central or state scheme funds are channelled.

Operational powers of the CAG

To actually perform these audits, the CAG has specific operational powers:

Access to all records: The CAG can call for any papers, documents, or records from any audited entity.
Inspection authority: Any office or organisation subject to audit can be physically inspected.
Power to question: The CAG can examine transactions and summon explanations from officials.
Decision on extent and manner: The CAG alone decides how deep an audit goes and what methods to use. No executive direction can modify, suppress, or change audit findings.

The CAG’s mandate covers almost every spending, revenue-collecting, or grant-receiving unit of the Central and State governments.

Use of INTOSAI and focus on public interest:

The CAG also consults the guidelines of the International Organization of Supreme Audit Institutions (INTOSAI) to determine what is relevant to citizens before finalising an audit subject

What the CAG does not audit:

The CAG does not audit private companies, even if they hold government contracts. If NHAI awards a highway contract to a private firm, the CAG audits NHAI’s processes and contract management, not the private contractor’s internal accounts.

However, the CAG can audit whether:

the contract was awarded correctly
payments were justified
value for money was achieved

Types of Audits Conducted by the CAG

The CAG does not conduct a single standard audit. There are several distinct types, each with a specific objective.

Audit Type	Core Question	Primary Focus
Financial Audit	Are the accounts accurate?	Financial statements
Compliance Audit	Was the law followed?	Rules, sanctions, regulations
Performance Audit	Was the money well spent?	Efficiency and outcomes
Propriety Audit	Was spending prudent?	Judgment and governance
IT Audit	Are systems secure and reliable?	Digital infrastructure

Financial Audit (Attestation Audit)

Examines whether financial statements accurately reflect actual transactions.

Legal basis: Section 19 of the CAG’s DPC Act, 1971, read with the Companies Act, 2013.

Checks: Whether government companies and departments have prepared their financial statements in accordance with the applicable financial reporting framework.

The key objective is to give an opinion: does the statement present a true and fair view of the financial position?

For government companies (PSUs) like ONGC, SAIL, or State Electricity Boards, the audit is conducted under Section 143(6) of the Companies Act, 2013. A statutory auditor (typically a chartered accountant) conducts the primary audit. The CAG then conducts a supplementary audit and comments on the auditor’s report.

The CAG has 60 days from the date of receiving the statutory audit report to complete this supplementary audit. The final report (auditor’s opinion + CAG’s comments) is placed before the Annual General Meeting of the company and shared with all shareholders.

Compliance Audit (Regularity Audit)

Checks whether transactions comply with applicable laws, rules, and sanctions.

If a ministry signed a contract without tendering or spent beyond its sanctioned limit, this audit would flag it. Compliance audit is the most frequently conducted type.

Legal basis: Sections 13, 15, 17 of the DPC Act.

Checks: Compliance audit is the most direct check on government spending. The CAG examines whether the money spent was:

Regular: Was there a legal provision or budgetary allocation?
Proper: Was the money used for the intended purpose?
Compliant: Did the spending follow all relevant rules, procurement guidelines, and financial codes?

The CAG may conduct test audits during the year, which can cover transactions across multiple financial years.

These audits explicitly look for cases of waste, mismanagement, irregularities, frauds, and corruption.

Performance Audit (Value for Money Audit)

It examines entire government programmes, schemes, or organisations and not just transactions.

Legal basis: CAG’s Auditing Standards (2017) and Regulations on Audit and Accounts, 2007.

Checks: The CAG examines three key criteria:

Economy: Was the resource (land, money, material) acquired at the right price?
Efficiency: Was the output maximised for the inputs used? (e.g., road length built per crore spent)
Effectiveness: Did the intended result actually happen? (e.g., Did the irrigation project actually increase crop yield?)

These audits do not just look at compliance. They question the wisdom of implementation.

For performance audits, the benchmarks against which performance is judged may not be directly available from rules; the CAG has to develop them based on international best practices and scheme objectives.

A performance audit of the PM Awas Yojana, for instance, would examine whether houses were actually built, who received them, and whether the per-unit cost was reasonable.

Propriety Audit

Examines whether expenditure was prudent. A purchase can be procedurally compliant and still be flagged as wasteful if the propriety audit finds it lacked common sense or business justification.

Legal basis: Derived from CAG’s DPC Act and upheld by the Supreme Court (2012 judgment).

Checks: The CAG examines whether taxpayer money was spent with integrity, whether wasteful expenditure was avoided even if technically legal, and whether the decision served the public interest.

Landmark Supreme Court ruling (2012): The Supreme Court explicitly upheld the CAG’s power to conduct propriety audits.

The Court rejected the government’s argument that the CAG should only check regularity, stating that reducing the CAG to a mere “bookkeeper” would defeat the constitutional purpose.

IT Audit

As government operations shift online, the CAG now audits IT systems, data integrity, software implementation, and cybersecurity practices.

This is a rapidly growing area, with audits covering systems like GSTN, PFMS, and Aadhaar-linked DBT platforms.

CAG Reports — How They Reach Parliament

The Constitution sets a clear hierarchy on how the CAG submits its reports: to the President (for central accounts) or Governor (for state accounts).

Only then are the reports placed before the legislature.

Here is the step-by-step journey of a CAG report from finalisation to public scrutiny:

Step 1: Field Audit

CAG teams conduct audits at government offices, PSU locations, and funded institutions across the country.

They examine vouchers, contracts, files, and accounts, and record their observations.

Step 2: Draft Inspection Report

Before a report becomes official, the CAG’s office follows a process to ensure fairness. Major audit findings are processed as draft paragraphs.

These drafts are sent to the concerned government department secretaries, who are given a specific period (usually six weeks) to submit their replies.

The government’s side is considered before the final audit paragraph is confirmed. If the department’s response is satisfactory, the paragraph might even be dropped from the final report.

Finally, an “exit conference” is held, allowing the ministry or department one last chance to offer arguments and supporting documents. Only after this does the CAG sign the report and send it to the President or the Governor.

Step 3: Response Review

If the department’s explanation is satisfactory, the finding is dropped.

If not, it is escalated within the IA&AD hierarchy and may be included in the final report as an audit “para.”

Step 4: Consolidated CAG Report

Audit findings are compiled into CAG Audit Reports.

Multiple reports are submitted each year covering Civil, Revenue, Defence, Railways, and other sectors at the Union level, plus separate reports for each state.

Step 5: Submission to President or Governor

This is the core legal step.Article 151 of the Constitution dictates the exact path:

For Union (Central) Accounts: The CAG’s reports are submitted to the President of India.
For State Accounts: The reports are submitted to the Governor of the State (or Lieutenant Governor for Union Territories).

The Constitution does not specify a time limit for the President or Governor to act on these reports. This lack of a deadline is a critical practical issue, as governments often delay the next step

Step 6: Laying Before the Legislature

Once the President or Governor receives the report, they are constitutionally required to “cause them to be laid” before the legislature. This means:

Centre: The President ensures the report is tabled in both Houses of Parliament (Lok Sabha and Rajya Sabha).
States: The Governor ensures the report is tabled in the State Legislative Assembly (Vidhan Sabha).

Step 7: Referral to the PAC

Once tabled, the reports are referred to the Public Accounts Committee for examination.

The PAC summons government officials, questions them on the report’s findings, and submits its own report back to Parliament with recommendations.

Step 8: Follow-up, Action Taken Reports

The final step is the government’s response. Based on PAC’s recommendations, the concerned ministry must submit Action Taken Notes (ATNs) to the Committee.

The PAC then finalises its views on these ATNs in a follow-up document called the Action Taken Report (ATR). This ATR is also placed in the Legislature, ensuring a complete audit cycle of identification, investigation, and rectification.

The full cycle, from audit to Parliament, takes about 12 to 18 months. By the time a report is tabled, the transactions audited may be two or three years old.

That time lag is a recognised limitation of the process.

Role of the Public Accounts Committee (PAC)

The CAG of India identifies financial irregularities. The Public Accounts Committee (PAC) makes sure someone does something about them.

The PAC is a parliamentary committee. It is not a constitutional body like the CAG. It was first established in 1921 under the Government of India Act, 1919.

After Independence, Parliament continued the system under its own rules. The legal authority comes from Rule 308 of the Rules of Procedure and Conduct of Business in Lok Sabha

Who Is on the PAC? (Composition)

The PAC has 22 members in total:

15 members from Lok Sabha (the lower house)
7 members from Rajya Sabha (the upper house)

Members are elected through proportional representation. This ensures smaller political parties also get representation.

By convention, the Chairperson belongs to the Opposition party in Lok Sabha. The Speaker of Lok Sabha appoints the Chairperson.

This is because the committee scrutinises the government. A ruling party member cannot be expected to aggressively question their own ministers. The convention ensures some level of political independence.

A minister cannot be a member of the PAC. If a member becomes a minister after being elected to the PAC, they automatically cease to be a member. This rule prevents the executive from controlling the committee from within.

Term length is one year. However, members are frequently re-elected, which maintains continuity.

What the PAC does:

Examines CAG audit reports tabled in Parliament
Summons ministry secretaries and senior officials to explain audit findings
Passes recommendations directing the government to take corrective action
Tracks compliance through Action Taken Reports (ATRs) submitted by ministries in response to its recommendations

The CAG works alongside the PAC throughout this process. Senior IA&AD officers brief committee members, attend hearings, and assist in the technical examination of witnesses.

Limitations of PAC

It examines past transactions, it cannot intervene in ongoing spending. Its recommendations are not legally binding.

The government is expected to comply, and generally does, but there is no automatic legal consequence for non-compliance.

A persistent problem is report backlog. Given the volume of CAG reports tabled annually, the PAC cannot always examine every significant finding within a reasonable timeframe. Reports sometimes remain unexamined for years.

For state legislatures, the equivalent body is the State Public Accounts Committee, which examines CAG reports on that state’s accounts and holds state departments accountable in the same manner.

CAG vs Statutory Auditor — Key Differences

If you work with government companies or PSUs, understanding the difference between a CAG audit and a regular statutory audit is essential.

Parameter	CAG Audit	Statutory Audit (CA Firm)
Legal basis	Constitutional / CAG Act, 1971	Companies Act, 2013
Appointment	CAG appoints the statutory auditor for govt companies	Appointed by shareholders at AGM
Audit scope	Financial, compliance, performance, propriety	Primarily financial statements
Objective	Public accountability to Parliament	Shareholder and regulatory accountability
Reporting	Parliament / state legislature	Shareholders, regulators (MCA, SEBI)
Independence	Constitutional guarantee	Professional independence (ICAI standards)
Access rights	Unrestricted access to all government records	Records of the specific company only
Fee	Determined by CAG / government	Determined by shareholders

For a government company, both audits happen concurrently. A CA firm is appointed as the statutory auditor, conducts the primary audit, and issues its report.

The CAG then conducts a supplementary audit, reviewing the CA firm’s work and adding its own observations where it identifies material issues.

If the CAG’s supplementary audit flags discrepancies, those comments are appended to the financial statements.

They appear alongside the statutory auditor’s report in the annual accounts and carry significant weight. Boards and management track these comments carefully, they feed directly into CAG reports tabled before Parliament.

The CAG can also direct the appointed CA firm to carry out specific audit procedures. In that sense, the CAG exercises a supervisory role over statutory auditors of government companies, a feature not commonly understood even among practitioners.

Notable CAG Reports That Changed India

Some CAG reports have directly shaped policy, triggered legal proceedings, and forced systemic reform.

Here are five CAG reports that fundamentally altered the Indian governance:

2G Spectrum Allocation

Report (2010): Examined how the Department of Telecommunications allocated 2G spectrum and UAS licenses in 2007-08.

Findings: 122 licenses issued at outdated 2001 prices instead of auctioning; estimated loss ₹58,000 crore – ₹1.76 lakh crore. Then Telecom Minister A. Raja bypassed advice from PMO, Finance Ministry, and TRAI.

Impact:

The Supreme Court cancelled all licenses (2012), calling the process arbitrary.
Criminal prosecutions followed.
Telecom policy shifted to mandatory auctions, boosting transparency and revenue.
Influenced reforms reflected in the Telecommunications Bill, 2023.

Coal Block Allocation (Coalgate)

Report (2012): Performance audit of coal block allocations to private firms without competitive bidding.

Findings: Estimated undue benefit of ~₹1.86 lakh crore; allocations lacked transparency. The PMO was drawn into controversy as the PM held the coal portfolio.

Impact:

The Supreme Court cancelled 214 of 218 blocks (2014), calling the process flawed.
Auctions introduced for future allocations, generating major revenues.
Multiple CBI investigations and FIRs against companies and officials.

Indian Railways Derailments Audit (2022)

Report: Reviewed railway safety (2017–21), focusing on derailments.

Findings: 1,127 derailments (69% of accidents); major causes included poor track maintenance, staff shortages, and ₹1.03 lakh crore funding gap in track renewal.

Impact:

Initially overlooked, but gained attention after the 2023 Balasore train accident.
Led to safety reforms: recruitment drives, increased funding, and greater transparency.

Rafale Deal Audit (2019)

Report: Audit of the 36-aircraft deal with Dassault Aviation signed in 2016.

Findings: Deal was 2.86% cheaper than the earlier UPA-era proposal; overall savings of 17.08% highlighted. However, offset obligations were not effectively implemented.

Impact:

Offset clause in defence deals scrapped (2020).
Shift in defence procurement strategy to reduce delays and improve efficiency.

GST E-Way Bill System Audit (2025)

Report: Performance audit of the GST e-way bill system.

Findings: System flaws allowed non-filers and cancelled taxpayers to generate e-way bills; tax leakage of ₹576.86 crore identified, along with ₹21,695 crore inconsistencies in GST data.

Impact:

CBIC tightened compliance and audit procedures.
GST Council reviewing system architecture to plug loopholes.

Frequently Asked Questions (FAQ)

1. What is CAG and who appoints CAG of India?

CAG stands for Comptroller and Auditor General of India. The CAG is appointed by the President of India, on the advice of the Council of Ministers.

2. Can the CAG audit private companies?

No. The CAG does not audit private companies, even if they hold government contracts. It audits government companies (where government equity exceeds 51%), autonomous bodies receiving substantial government funding, and public sector undertakings. It can, however, audit the processes by which the government awarded contracts to private entities.

3. What happens after the CAG submits its report to Parliament?

The report is tabled in Parliament by the President (or by the Governor, for state reports) and referred to the Public Accounts Committee. The PAC then examines the findings, calls officials for explanation, and issues recommendations.

4. Is the CAG’s report legally binding on the government?

No. CAG audit reports are not legally binding directives. They are presented to Parliament. The PAC issues recommendations, and the government submits Action Taken Reports in response. However, there is no automatic legal sanction for non-compliance.

5. How is the CAG different from the CVC?

The CAG is an auditor, it examines government accounts and reports findings to Parliament. The Central Vigilance Commission (CVC) is an anti-corruption oversight body. It deals with vigilance matters and corruption complaints against government officials. Their mandates are complementary but distinct.
