Comptroller and Auditor General of India (CAG)

The Constitution of India provides for an independent office of the Comptroller and Auditor General of India (CAG). He is the head of the Indian audit and accounts department. He is the guardian of the public purse and controls the financial system of the country both at the central level and state level.

CAG is one of the strongest walls of the democratic system, as the Supreme Court, Election Commission of India (ECA), and the Union Public Service Commission (UPSC).

Background of CAG

The role of CAG evolved in British India with Lord Canning. In 1858 for the first time, a separate department was set up for auditing and accounting transactions under the East India Company.

Roles of CAG

1. The CAG is an agent of the Parliament and conducts audits of expenditure on behalf of the Parliament. Therefore he is responsible only to the Parliament.

2. The CAG has to ascertain whether the money spent was authorised for the purpose for which they were spent.

3. He focuses on whether the expenditure made is in the public interest or not.

4. The role of CAG in the auditing of public corporations is limited.

5. Some corporations are audited directly by the CAG. For example, ONGC, Air India, and others.

6. Some corporations are audited by private professional auditors who are appointed by the Central Government in consultation with CAG. If necessary, there may be a supplementary audit by CAG.

7. The role of the CAG in the auditing of Government Companies is also limited. They are audited by private auditors who are appointed by the Central Government on the advice of the CAG.

Audit Board, 1968

In 1968 an Audit Board was established as a part of the office of CAG to associate with outside specialists and experts to handle technical aspects of the audit. Board was established on the recommendation of the Administration Reforms Commission of India.

Mode of Appointment

The selection process is entirely internal to the Government as to what criteria are applied and how names are shortlisted. Presently there is a lack of clarity.

Recent Example

Two PILs have also been filed in Supreme Court against the former Defence Secretary Shashi Kant Sharma as CAG (2014-17). His appointment is thus being questioned in the context of conflict of interest and also that it goes against the code of ethics of auditors.


There is a need to frame a transparent selection procedure based on definite criteria. A selection committee may be appointed in this regard.

Current CAG

The current Comptroller and Auditor General of India (CAG) is G.C. Murmu (from August 2020). He is the 14th CAG of India.

Before Murmu, it was Rajiv Mehrishi who held the position from 2017 to 2020. He was elected as Vice Chairman of the United Nations Panel of External Auditors at its annual meeting held in New York.

V Narahari Rao was the first Indian Civil Servant who served as CAG.
