Part 1: Why Financial Committees Exist

700+ MPs cannot audit thousands of line items in plenary session without halting legislative business. Parliament delegates financial scrutiny to small cross-party committees.

Core Rule: The Executive cannot spend a single rupee without Parliamentary approval, nor spend differently from Parliamentary intent.

Frequently Asked Questions

What are the three major Financial Committees of the Indian Parliament?

The three major Financial Standing Committees of Parliament are: 1. Public Accounts Committee (PAC), 2. Estimates Committee, and 3. Committee on Public Undertakings (COPU).

Why does the Estimates Committee have members ONLY from the Lok Sabha?

The Estimates Committee consists of 30 members, all from the Lok Sabha. Rajya Sabha has no representation because the Lok Sabha holds exclusive constitutional primacy over money bills, taxation, and budget estimates under the Indian Constitution.

Who heads the Public Accounts Committee (PAC)?

By a democratic convention established in 1967-68, the Chairman of the Public Accounts Committee (PAC) is always appointed by the Speaker from an Opposition party.

Can a Cabinet Minister be a member of any Financial Committee?

No. Cabinet Ministers are strictly barred from being elected as members of the PAC, Estimates Committee, or COPU. If an elected member is appointed as a minister, they must vacate their committee seat immediately.

Why is the CAG called the 'Friend, Philosopher, and Guide' of the PAC?

The Comptroller and Auditor General (C&AG) prepares the underlying audit reports, attends PAC meetings, helps select key audit paragraphs for deep scrutiny, and assists MPs in formulating technical questions for civil servants.

What is an Action Taken Report (ATR)?

An Action Taken Report (ATR) is an follow-up report where the executive must respond within a set period (typically 6 months) explaining how it implemented the committee's recommendations or why it could not.

When were PAC, Estimates Committee, and COPU established?

PAC was established in 1921 (Montagu-Chelmsford Reforms), Estimates Committee in 1950 (Dr. John Mathai recommendation), and COPU in 1964 (Krishna Menon Committee recommendation).
