What is the Comptroller and Auditor General?

The Comptroller and Auditor General of India (CAG) is the supreme audit institution of the country and one of the most important constitutional authorities. Established under Article 148 of the Constitution, the CAG audits all receipts and expenditure of the Government of India, state governments, and bodies substantially financed by the government. Dr. B.R. Ambedkar described the CAG as "the most important officer in the Constitution of India" — more important, in his view, than even the judiciary.

The CAG is appointed by the President of India by warrant under his hand and seal. The first CAG of independent India was V. Narahari Rao (1948-1954). The current (15th) CAG is K. Sanjay Murthy, who assumed office on 21 November 2024, succeeding Girish Chandra Murmu.

The CAG's reports are the foundation of parliamentary financial accountability. At the Union level, these reports are submitted to the President, who causes them to be laid before Parliament. The Public Accounts Committee (PAC) of Parliament examines the CAG's reports. At the state level, reports go to the Governor and are examined by the state legislature's PAC. The CAG also serves as the auditor of accounts of the United Nations and its specialised agencies — Girish Chandra Murmu was elected as WHO's external auditor in 2023.
