The Duties and Powers of the Comptroller and Auditor General of India

When a massive government scheme runs into allegations of irregularity, there is one office whose report everyone waits to read. That office belongs to the Comptroller and Auditor General, or CAG, of India. Often described as the guardian of the public purse, the CAG sits at the heart of India’s system of financial accountability, making sure that every rupee spent by the government is spent lawfully, economically and for its intended purpose.

Who is the Comptroller and Auditor General 🔗

The CAG is an independent constitutional authority created under Article 148 of the Constitution of India. The office heads the Indian Audit and Accounts Department (IAAD), which functions as the Supreme Audit Institution (SAI) of the country. This is not just a bureaucratic title. It means the CAG is responsible for auditing the finances of both the Union and the State governments, and holds a status equivalent to a judge of the Supreme Court of India.

The importance of this institution was captured famously by Dr. B.R. Ambedkar during the Constituent Assembly debates. He described the CAG as one of the most important officers under the Constitution of India, placing the office on par with the Supreme Court, the Election Commission and the Union Public Service Commission as a guardian of democratic governance. Because of its watchdog role, many scholars refer to the institution as the fifth pillar of Indian democracy.

The constitutional foundation: Articles 148 to 151 🔗

The duties and powers of the CAG are primarily drawn from four constitutional provisions, supplemented by a parliamentary statute. Understanding each article helps us see how the framers built a fortress of financial accountability.

Article 148: Establishment of the office 🔗

Article 148 establishes the office of the CAG, appointed by the President of India by warrant under his hand and seal. To protect the independence of the position, the CAG can only be removed in the same manner and on the same grounds as a judge of the Supreme Court, which requires a resolution passed by both Houses of Parliament with a special majority on grounds of proved misbehaviour or incapacity.

The administrative expenses of the CAG’s office, including salaries, allowances and pensions, are charged upon the Consolidated Fund of India and are not subject to vote in Parliament. This financial insulation ensures that the executive cannot pressure the CAG by threatening its budget.

Article 149: Duties and powers 🔗

This is the core operational article. It empowers Parliament to prescribe the duties and powers of the CAG in relation to the accounts of the Union, the States and any other authority or body. Until such a law is enacted, the CAG continues to exercise the powers of the earlier Auditor-General of India.

Article 150: Form of accounts 🔗

Article 150 gives the CAG an advisory role in the technical architecture of public accounting. The accounts of the Union and the States are kept in such form as the President may prescribe on the advice of the CAG. This ensures uniformity and transparency in how government finances are recorded across the country.

Article 151: Submission of audit reports 🔗

Article 151 deals with the reporting mechanism. Reports relating to the accounts of the Union are submitted to the President, who lays them before each House of Parliament. Similarly, state-level audit reports go to the Governor, who places them before the state legislature. This ensures that CAG findings reach the democratically elected representatives who can then question the executive.

The CAG’s (DPC) Act, 1971: Giving teeth to the Constitution 🔗

Using the mandate under Article 149, Parliament enacted the Comptroller and Auditor General’s (Duties, Powers and Conditions of Service) Act, 1971, commonly known as the DPC Act. This is the principal legislation that puts almost every government spending and revenue-collecting body under the audit scanner of the CAG.

The Act has been amended four times, in 1976, 1984, 1987 and 1994, to respond to evolving governance needs. In 1976, the CAG was relieved of the responsibility of compiling and maintaining the accounts of the Government of India due to the separation of accounts from audit through departmentalisation.

Core duties of the CAG 🔗

Let’s unpack what the CAG actually does day to day. These responsibilities flow from both the Constitution and the DPC Act.

Audit of the Consolidated Fund 🔗

Section 13 of the DPC Act tasks the CAG with auditing all expenditures from the Consolidated Fund of India and of each State, ensuring that public funds are used for lawful and intended purposes in line with legislative approval. This is the bread-and-butter of the CAG’s work: verifying that every rupee drawn from the main government treasury was authorised by Parliament or the state legislature.

Audit of the Contingency Fund and Public Account 🔗

The CAG also audits all transactions relating to the Contingency Fund of India and the Public Account of India, along with the corresponding funds of each state. The Contingency Fund handles unforeseen emergencies, while the Public Account holds money where the government acts as a banker, such as provident funds and small savings.

Audit of government receipts 🔗

Auditing is not limited to what the government spends. The CAG also examines what the government collects, ensuring that taxes, duties, fees and other receipts are properly assessed, collected and credited.

Audit of government companies and corporations 🔗

Public sector undertakings are a huge part of India’s economy. The CAG is the statutory auditor of Government-owned corporations and conducts supplementary audit of government companies in which the government has an equity share of at least 51 percent or subsidiary companies of existing government companies. Think of organisations like ONGC, the Damodar Valley Corporation or Indian Oil Corporation; all fall within this orbit.

Audit of trading and commercial accounts 🔗

Government departments that engage in trading, manufacturing or commercial operations maintain profit and loss accounts and balance sheets. These too are subject to CAG audit, bringing commercial-style scrutiny to public enterprises.

Certifying net proceeds of taxes 🔗

Under Article 279, the CAG has the unique power to ascertain and certify the net proceeds of any tax or duty, and this certificate is final. Net proceeds mean the total collection minus the cost of collection. This figure directly influences how taxes are shared between the Centre and the States through the Finance Commission’s formula.

Types of audit conducted by the CAG 🔗

Modern auditing goes beyond the accountant-with-a-pencil stereotype. The CAG conducts several distinct types of audits, each with a different purpose.

Financial audit 🔗

This traditional form checks whether the accounts fairly represent the government’s financial position and whether transactions are properly recorded. It is essentially a test of honesty and accuracy in bookkeeping.

Compliance audit 🔗

Compliance audit evaluates whether expenditures have been made in accordance with the laws, rules and regulations that govern them. If a department spends money on something Parliament did not authorise, the compliance audit will flag it.

Performance audit 🔗

This is where the CAG moves from “was the money spent legally” to “was it spent wisely”. Under Section 23 of the DPC Act, the CAG has powers to make regulations for the scope and extent of audit, and on that basis has been conducting performance audits in addition to financial audits and compliance audits. Performance audits examine the economy, efficiency and effectiveness of government programmes; whether schemes actually deliver results on the ground.

Powers that make these duties enforceable 🔗

Duties without power are just wishful thinking. The DPC Act arms the CAG with several tools to make audits meaningful.

The CAG can inspect any office or department which is subject to his audit, examine all transactions and question the person in charge, call for any records, papers and documents from any audited entity, and decide the extent and manner of the audit. This gives the institution the investigative muscle to dig deep into suspicious transactions or systemic inefficiencies.

The three reports that shape public debate 🔗

Every year, the CAG submits three main audit reports to the President: the Audit Report on Appropriation Accounts, which compares actual expenditure with the amounts sanctioned by Parliament through the Appropriation Act; the Audit Report on Finance Accounts, showing annual receipts and disbursements of the Union Government; and the Audit Report on Public Undertakings. These reports are placed before Parliament, where the Public Accounts Committee (PAC) and the Committee on Public Undertakings (COPU) examine them in detail. The CAG acts as a guide, friend and philosopher to these committees, translating technical findings into actionable oversight.

Why the CAG matters for good governance 🔗

The CAG’s work is not just an accounting exercise. Its reports have historically triggered some of the most consequential public debates in India, from questions about spectrum allocation to coal block distribution to public welfare scheme implementation. By bringing irregularities into the open, the institution strengthens parliamentary control over the executive, protects taxpayer money and reinforces citizen trust in democratic institutions.

At the same time, there are ongoing conversations about reform. Former CAG Vinod Rai had suggested bringing all private-public partnerships, Panchayati Raj Institutions and government-funded societies within the ambit of the CAG, and amending the 1971 Act to match the pace of modern governance. Debates also continue around the method of appointment, the timeliness of reports and the need for a statutory footing for the IAAD.

What do you think? In an era where governments increasingly use private partnerships, special purpose vehicles and digital service delivery to spend public money, should the CAG’s audit jurisdiction be expanded to cover every rupee of taxpayer value, no matter where it finally lands? And how can the institution balance its independence with the need to engage constructively with a modern executive?
