Parliamentary Committees: Composition, Functions and the Exam Traps

Parliament cannot examine every Bill clause by clause, every rupee of the Budget, or every ministry's performance in a full floor debate. Its business is, in the Lok Sabha Secretariat's own words, "not only varied and complex in nature, but also considerable in volume," and the time available on the floor is limited. So a large share of the real, detailed scrutiny is pushed into smaller bodies of members: parliamentary committees. Because a committee is drawn from the same House (or both Houses), works under the same rules, and eventually reports back to the House, it is often described as a "Parliament in miniature," a smaller, more focused version of the same institution doing the close reading the floor has no time for.

This site's dedicated Parliament note already covers the Speaker, sessions and legislative procedure, and touches committees briefly as part of that institutional picture. This note goes much deeper into the committee system itself: exact membership numbers, who chairs what, and the specific statement-based traps UPSC has actually used.

This chapter's material overlaps with NCERT Class 11, Indian Constitution at Work, Chapter 5 (Legislature). This note goes further than that chapter's coverage.

Standing committees and ad hoc committees: the basic split

Parliamentary committees fall into two broad categories.

Standing Committees are permanent (or near-permanent) bodies. They continue from one session to the next and are reconstituted periodically, usually annually, for the life of the House they belong to. The three Financial Committees, the Departmentally Related Standing Committees, and bodies such as the Business Advisory Committee, the Committee on Petitions and the Rules Committee all fall in this category.

Ad hoc Committees are temporary. They are created for a specific, defined task and cease to exist once that task is done. The clearest examples are a Select Committee or Joint Committee set up to examine one particular Bill, and inquiry committees set up to investigate a specific matter, such as the Joint Parliamentary Committees (JPCs) that have been constituted over the decades to investigate major financial scams. Once the Bill is reported on or the inquiry report is submitted, the committee is dissolved.

The three Financial Committees

Three committees predate the wider committee system and remain, in a real sense, its backbone. All three exclude Ministers from membership, a rule stated explicitly in the Lok Sabha's own Rules of Procedure for each of them, precisely so the body scrutinising government spending is not staffed by the government itself.

Public Accounts Committee (PAC)

The PAC examines the accounts showing how money granted by Parliament was actually spent, principally by scrutinising the Appropriation Accounts, the Finance Accounts, and the various reports of the Comptroller and Auditor General (CAG) on revenue, expenditure and the accounts of autonomous bodies. Its job is not just to check that spending stayed within the sanctioned amount, but to examine its "wisdom, faithfulness and economy," which is why the PAC routinely flags cases of loss, wasteful expenditure and financial irregularity and calls the concerned ministry to account for them.

Composition: 22 members, comprising 15 members elected by the Lok Sabha from among its own members by proportional representation using the single transferable vote, plus not more than 7 members of the Rajya Sabha, nominated by that House to be associated with the Committee. The Chairperson is appointed by the Speaker from among the Lok Sabha members elected to the Committee. A Minister is not eligible to be a member; if an existing member is later made a Minister, that member ceases to hold the seat from the date of appointment. By a well-established convention dating to 1967, the PAC's Chairman is drawn from the principal Opposition party, not the ruling party, which is what makes it, in practice, an opposition-led check on government accounts.

Estimates Committee

The Estimates Committee examines the estimates in the Budget and reports what economies, administrative reforms or improvements in efficiency can be made "consistent with the policy underlying the estimates." Crucially, it examines whether public money is being well spent within the limits of existing policy; it does not question the policy itself, only its administrative efficiency.

Composition: 30 members, elected annually by the Lok Sabha alone from among its own members, again by proportional representation with a single transferable vote. The Rajya Sabha has no representation at all on this committee, the one clean, testable exception among the three Financial Committees. As with the PAC, a Minister cannot be a member. The Chairperson is appointed by the Speaker from among the Committee's members and, by convention, is almost always drawn from the ruling party or coalition, the mirror image of the PAC's Opposition-chair convention.

Committee on Public Undertakings (COPU)

The Committee on Public Undertakings examines the reports and accounts of Central Public Sector Undertakings (CPSUs) listed in the Fourth Schedule to the Lok Sabha's Rules of Procedure, and any CAG reports on them, to see whether these undertakings are run on sound business and commercial principles. It absorbed functions the PAC and Estimates Committee used to perform for public undertakings before it was set up, but it deliberately stays out of three things: matters of major government policy (as distinct from an undertaking's business functions), day-to-day administration, and matters that a special statute already assigns to a dedicated body.

Composition: not more than 22 members, comprising 15 members elected by the Lok Sabha by proportional representation with a single transferable vote, plus not more than 7 members nominated by the Rajya Sabha, the same 15-plus-7 shape as the PAC. A Minister cannot be a member here either, and the Chairperson is appointed by the Speaker from among the Committee's members.

Departmentally Related Standing Committees (DRSCs)

DRSCs were created to give Parliament continuous, ministry-by-ministry oversight rather than the occasional, ad hoc scrutiny of the older system. The Lok Sabha and Rajya Sabha adopted rules establishing 17 DRSCs on 29 March 1993, formally constituted from 8 April 1993, replacing three broader subject committees that had existed since 1989. After more than a decade of experience with the 17-committee system, it was restructured in July 2004, and the number was raised to 24, the figure that still stands. Sixteen of these 24 work under the Speaker of the Lok Sabha's jurisdiction (Part II of the list) and eight work under the Chairman of the Rajya Sabha (Part I), between them covering every ministry and department of the Union government.

Each DRSC has 31 members: 21 from the Lok Sabha and 10 from the Rajya Sabha, nominated respectively by the Speaker and the Chairman of the Rajya Sabha, with seats allocated across parties roughly in proportion to their strength in each House. This is smaller than the pre-2004 arrangement, when each of the original 17 committees had 45 members (30 Lok Sabha, 15 Rajya Sabha). As with the Financial Committees, a Minister cannot be a member, and the term of office is one year.

A DRSC's core functions are to:

• consider the Demands for Grants of its ministries and report on them (without suggesting anything in the nature of a cut motion);
• examine such Bills pertaining to its ministries as are specifically referred to it by the Speaker or the Rajya Sabha Chairman;
• consider the annual reports of its ministries and departments; and
• examine long-term policy documents referred to it.

The crucial caveat, worth stating precisely because it is exactly what UPSC likes to test: a DRSC's reports have persuasive, not binding, value. They are, in the Lok Sabha Secretariat's own description, "treated as considered advice given by the Committee." The Demands for Grants and Bills a DRSC has reported on are considered by the House in light of that report, but the House is not bound to accept it, and referring a Bill to a DRSC in the first place is discretionary, not mandatory. That discretion is exactly why the referral rate has become a live concern in its own right (see the Mains angle below).

Select Committee and Joint Committee: ad hoc scrutiny of a Bill

When a particular Bill needs closer examination than the floor can give it, either House may set it up before a Select Committee, drawn only from the members of that one House, or, for a Bill of wider importance, both Houses may together set up a Joint Committee, drawn from members of both the Lok Sabha and the Rajya Sabha. Both are ad hoc: their composition, mandate and reporting deadline are laid down in the motion that creates them, and once the committee reports on the Bill it was formed for, it is dissolved. Recent Joint Committees have examined Bills such as the Insolvency and Bankruptcy Code, 2015, the Personal Data Protection Bill, 2019, and the Forest (Conservation) Amendment Bill, 2023.

A related but distinct use of the Joint Committee format is the Joint Parliamentary Committee (JPC) set up not to examine a Bill but to investigate a serious matter of fraud or corruption that has agitated public opinion, formed by consensus between the government and the Opposition. JPCs on the Bofors contract (1987), securities and banking irregularities (1992), the 2001 stock market scam, and the 2011 telecom licences and spectrum allocation are the standard cited examples. A JPC becomes functus officio, its work legally complete, once it submits its report.

Other significant committees worth naming precisely

Beyond the Financial Committees and the DRSCs, several other Standing Committees carry out specific, narrowly defined jobs, and UPSC has tested several of them by name.

• Business Advisory Committee: 15 members, including the Speaker, who is its ex officio Chairperson. It decides the timetable for government legislative business, recommending how much time should be allotted to each stage of a Government Bill or other item, and presents this as a report the House then formally adopts.
• Committee on Government Assurances: not more than 15 members, nominated by the Speaker. It tracks the assurances, promises and undertakings Ministers give on the floor (during Question Hour or debates on Bills, resolutions and motions) and reports on whether, and how promptly, each has actually been implemented. It has set an outer limit of three months for implementing an assurance, and, notably, pending assurances do not lapse merely because the Lok Sabha is dissolved.
• Committee on Petitions: 15 members nominated by the Speaker. It examines petitions formally submitted to the House, directs how they should be circulated, and reports back with remedial suggestions.
• Committee of Privileges: 15 members nominated by the Speaker. It examines every question of parliamentary privilege referred to it, decides whether a breach occurred, and recommends the House's course of action.
• Rules Committee: 15 members, including the Speaker, its ex officio Chairperson. It considers matters of procedure and conduct of business in the House and recommends amendments to the Rules themselves.
• Committee on Subordinate Legislation: 15 members nominated by the Speaker. This is the committee UPSC has already tested directly (2018): it scrutinises whether the executive's rule-making power, delegated by a parent Act or the Constitution, is being exercised properly, for instance checking that a rule or bye-law does not exceed the Act's objects, does not impose a tax, does not oust the courts' jurisdiction, and was not laid before the House after unjustifiable delay.

The exam angle: where UPSC actually sets the trap

Statement-based questions on this chapter almost never test whether you know a committee's name and general purpose; they test whether you can keep three near-identical facts straight across three committees at once. The recurring trap has three moving parts:

1. Exact composition. PAC and COPU both run 22 members split 15 Lok Sabha plus up to 7 Rajya Sabha; the Estimates Committee runs 30 members, all Lok Sabha. A statement that gives the Estimates Committee any Rajya Sabha members, or gives the PAC/COPU a different split, is the classic wrong option.
2. Lok-Sabha-only versus mixed. Only the Estimates Committee among the three Financial Committees excludes the Rajya Sabha entirely. Every DRSC, by contrast, always draws from both Houses (21 Lok Sabha, 10 Rajya Sabha).
3. Which party chairs which committee. The PAC's Chairman is, by convention, from the main Opposition party; the Estimates Committee's Chairman is, by convention, from the ruling party. A question that swaps these two conventions, or claims either is a written constitutional rule rather than a settled parliamentary convention, is testing exactly this reversal.

The 2024 Ethics Committee question and the 2018 Subordinate Legislation question both worked the same way: naming a specific, real committee and testing whether you know its precise, distinguishing function rather than a vague description that could fit several committees.

Quick revision points

• Financial Committees: PAC and COPU are 22 members (15 LS + up to 7 RS); Estimates is 30, Lok Sabha only. All three exclude Ministers.
• DRSCs: grew from 17 (1993) to 24 (2004 restructuring); 31 members each, 21 Lok Sabha and 10 Rajya Sabha; reports are recommendatory, not binding on government.
• Select Committee examines a Bill with members of one House only; Joint Committee does the same with members of both Houses; both are ad hoc and dissolve once their report is submitted.
• Committee on Subordinate Legislation checks delegated rule-making power; Committee on Government Assurances checks whether floor promises were actually kept; Business Advisory Committee sets the legislative timetable.

Composition and chair-convention questions reward precision, not general familiarity. Once these numbers and party conventions are genuinely fixed in memory, practise the statement-based questions on this chapter to see how UPSC actually mixes and swaps them.
