Comptroller and Auditor General (CAG)

Established under Article 148 of the Constitution, the Comptroller and Auditor General (CAG) of India is a constitutional body. Its key role is to audit all the receipts and expenditures of the central government, state governments, and those bodies or authorities which are heavily financed by the government. Additionally, the CAG also plays the role of an external auditor to government-owned corporations. It conducts audits of any non-banking company in which the Union Government has a share of 51% or more.

The CAG's reports are presented to the Parliament of India. These reports are a source of key consideration for special committees in the Union and State Legislatures such as the Public Accounts Committees (PACs) and Committees on Public Undertakings (COPUs).
