Frequently Asked Questions

Which articles of the Indian Constitution govern the Comptroller and Auditor General (CAG)?

Articles 148 to 151 in Part V (Chapter V) of the Indian Constitution govern the office, duties, powers, and audit reports of the Comptroller and Auditor General (CAG) of India.

Why did Dr. B.R. Ambedkar call the CAG 'the most important officer in the Constitution'?

Dr. Ambedkar considered the CAG the most important officer because the CAG acts as the Guardian of the Public Purse, ensuring that executive spending remains transparent, accountable, and legally compliant.

How is the CAG appointed and what is their tenure?

The CAG is appointed by the President of India by warrant under his hand and seal. The CAG holds office for a term of 6 years or until reaching the age of 65 years, whichever is earlier.

How can the CAG be removed from office?

The CAG can only be removed by the President following an address passed by both Houses of Parliament with a special majority, on grounds of proved misbehaviour or incapacity (the exact procedure used for removing a Supreme Court Judge).

What is the difference between a Regulatory Audit, Propriety Audit, and Performance Audit?

Regulatory Audit checks legal compliance with budgetary sanctions. Propriety Audit evaluates whether spending was economically wise, prudent, and free from extravagance. Performance Audit assesses whether public welfare schemes achieved real-world goals efficiently.

What is the relationship between the CAG and the Public Accounts Committee (PAC)?

The CAG acts as the 'Friend, Philosopher, and Guide' to the Public Accounts Committee (PAC) of Parliament. The PAC examines CAG audit reports and grills executive officials on financial discrepancies.

How does the Indian CAG differ from the UK CAG?

The UK CAG has prior control over treasury releases (no money can be spent without UK CAG approval). The Indian CAG has no prior control over treasury withdrawals and functions primarily as a post-facto auditor.

What are the three primary public funds audited by the CAG?

The CAG audits the Consolidated Fund of India/States (Article 266), the Contingency Fund of India/States (Article 267), and the Public Account of India/States (Article 266).
