Sessions of Parliament

The Indian Parliament meets in three sessions every year. There is no constitutional provision prescribing how many sessions must be held, but Article 85 mandates that no more than six months shall intervene between two consecutive sessions.

SessionUsual PeriodKey Business
Budget SessionLate January / February to MayUnion Budget presentation, Finance Bill, grants
Monsoon SessionJuly to August/SeptemberLegislation, supplementary demands
Winter SessionNovember to DecemberPending legislation, policy discussion

The session begins with the summons issued by the President on the advice of the Cabinet. A session ends with prorogation by the President. It is important to distinguish prorogation from adjournment and dissolution:

  • Adjournment — Suspends a sitting temporarily (hours, days, weeks). Business is not lost; it resumes when the House meets again.
  • Adjournment Sine Die — Terminates a sitting indefinitely without a fixed reassembly date.
  • Prorogation — Formally ends a session. Issued by the President. Pending notices (questions, motions, resolutions) lapse on prorogation. However, Bills pending in either House do NOT lapse on prorogation — they continue to the next session. (UPSC frequently traps aspirants on this distinction.)
  • Dissolution — Terminates the Lok Sabha itself; requires fresh elections. The Rajya Sabha, being a permanent House, is never dissolved.

Bill-lapse rules on dissolution (Article 107(5)):

  • Lapse: (a) Bill originating in Lok Sabha and pending in Lok Sabha; (b) Bill passed by Lok Sabha and pending in Rajya Sabha; (c) Bill returned by Rajya Sabha with amendments and pending in Lok Sabha
  • Survive: (a) Bill pending in Rajya Sabha but not yet passed by Lok Sabha; (b) Bills passed by both Houses and pending Presidential assent; (c) Bills returned by President for reconsideration (not yet re-passed)

UPSC trap (Prelims 2016 tested this): A Bill pending in Rajya Sabha but not yet passed by Lok Sabha SURVIVES Lok Sabha's dissolution — because the Rajya Sabha is permanent.


Question Hour

The first hour of every sitting is Question Hour, during which MPs hold ministers accountable for their ministries. It is considered the most vibrant time in Parliament for executive accountability.

Types of Questions

TypeOral/WrittenSupplementary QuestionsDistinguishing Feature
Starred (*)Oral answerAllowedMarked with an asterisk; requires minister to give oral reply on the floor
UnstarredWritten answerNot allowedMinister submits a written reply; no follow-up
Short NoticeOral answerAllowedRaised with less than 10 days' notice; relates to a matter of urgent public importance; Speaker decides admissibility

The 15-day advance notice rule applies to starred and unstarred questions. The time allotted for a starred question and supplementary questions is limited to keep the proceeding efficient.


Zero Hour

Zero Hour is an Indian parliamentary innovation that has no mention in the Constitution or Rules of Procedure. It starts immediately after Question Hour (at noon — hence "Zero Hour") and allows MPs to raise matters of urgent public importance without any prior notice.

  • Commenced in the Indian Parliament in 1962
  • Ministers are expected to respond or make statements
  • Unlike Question Hour, Zero Hour is not regulated by any formal rules — it operates on convention

Parliamentary Motions

Several parliamentary devices allow MPs to raise issues or check the executive:

DevicePurposeKey Feature
Calling Attention MotionCall a minister's attention to a matter of urgent public importanceMinister makes a brief statement; no debate allowed
Adjournment MotionDiscuss a definite matter of urgent public importanceRequires support of at least 50 MPs, leave of the Speaker, and Speaker's permission. Only in Lok Sabha (NOT Rajya Sabha). If passed, displaces normal business for the day — treated as a censure
No-Confidence MotionTest the majority of the Council of MinistersCan only be introduced in Lok Sabha (Article 75); if passed, the government must resign
Motion of Thanks on President's AddressDebate on President's address (Article 87)Amendments moved to add items the government did not mention
Censure MotionCensure a specific minister or the governmentUnlike no-confidence motion, need not lead to resignation; less severe
Cut MotionsReduce the amount of a demand in the budgetThree types: (a) Disapproval of Policy Cut — reduces demand to ₹1 to express disapproval; (b) Economy Cut — reduces by specific amount as economy measure; (c) Token Cut — reduces demand by ₹100 to express specific grievance

Discussion Devices — Rule 184 vs Rule 193 vs Half-an-Hour

Parliament has multiple devices for raising matters short of full-fledged motions. UPSC has tested the distinctions.

DeviceRuleKey FeatureVoting
Discussion under Rule 184LS Rule 184 / RS Rule 167Discussion with a formal motion; can include amendmentsVote taken at the end
Discussion under Rule 193 (LS) / Rule 176 (RS)Rule 193 / 176Short-duration discussion (max 2.5 hours); NO formal motion; no amendmentsNO vote taken
Half-an-Hour Discussion (Rule 55)Rule 55Discussion on a matter of sufficient public importance arising out of a recent question; raised after Question Hour endsNo vote
Calling Attention Motion (Rule 197)Rule 197Member calls minister's attention to urgent matter; minister makes brief statementNo formal vote
Half-an-Hour DiscussionTuesday/Thursday/Friday last half hour3 MPs eligible per sitting; raised by ballotNo vote

UPSC trap: Rule 184 = WITH vote. Rule 193 = WITHOUT vote. Confusing the two is a recurring Prelims trap.

Closure Motions

A Closure Motion is moved by a member to cut short debate on a matter. Four types:

TypeOperation
Simple Closure"That the question be now put" — Speaker may decide
Closure by CompartmentsClauses/sections of a Bill grouped and put together to a vote
Kangaroo ClosureOnly important clauses selected for debate; rest skipped to save time
GuillotineAt the end of allocated time, all undiscussed portions are put to vote without further debate — most commonly used in Demands for Grants

Voting Methods

MethodWhen Used
Voice VoteDefault — Speaker calls "Ayes" and "Noes"; declares result based on volume
DivisionRecorded vote — pressing yellow/red/green buttons on individual desks; called by Speaker or demanded by any member
Casting Vote (Article 100(1))Speaker votes ONLY when there is a tie; Speaker has no first-instance vote
Secret BallotUsed for Speaker / Deputy Speaker election; also for impeachment of President

Whip System

A Whip is an instruction by a political party to its MPs/MLAs on how to vote in the House. Three intensity levels:

WhipSignificance
One-line whipMPs informed of vote; absence allowed — no party action
Two-line whipMPs must be present; can vote according to conscience
Three-line whipMPs must be present and vote according to party direction; defiance triggers anti-defection under Tenth Schedule

Connection to anti-defection: A three-line whip is the trigger mechanism for the 10th Schedule. Voting against (or abstaining from) the party direction on a three-line whip is a "voluntary giving up" of party membership — leading to disqualification.

Resolutions vs Motions

TypeInitiatorEffect
Government ResolutionA ministerGovernment's policy statement; passed in normal course
Private Member ResolutionAny MP not a ministerPersuasive only; rarely passed
Statutory ResolutionEither HouseRequired by a specific statute (e.g., approval of Emergency Proclamation under Art 352)

Types of Bills

Classification by Origin

TypeIntroduced byRequires Prior Permission
Government BillA ministerNo — introduced as a matter of right
Private Member BillAny MP who is not a ministerYes — ballot system used; Fridays reserved

Private Member Bills rarely become law; their primary value is in raising public debate and signalling legislative priorities. The last Private Member's Bill to be passed by both Houses and become law was the Supreme Court (Enlargement of Criminal Appellate Jurisdiction) Bill, 1968, enacted as an Act in 1970 — i.e., no Private Member's Bill has been passed in over 50+ years. This is a recurring Prelims/Mains data point demonstrating the decline of MPs' legislative initiative.

Classification by Subject Matter

Ordinary Bills (Article 107-108)

  • Can be introduced in either House
  • Passed separately by both Houses; if disagreement persists, joint sitting convened (Article 108)
  • President can give assent, withhold assent, or return for reconsideration (not to Money Bills)

Money Bills (Article 110)

  • Deal exclusively with taxation, government borrowing, Consolidated Fund — as defined in Article 110(1)(a) to (g)
  • Can only be introduced in Lok Sabha
  • Rajya Sabha has 14 days to return — its recommendations are not binding on Lok Sabha
  • No joint sitting for Money Bills — Lok Sabha alone decides
  • Speaker certifies whether a Bill is a Money Bill

Finance Bills

  • Category I: Contains provisions of Article 110 plus other matters — treated like a Money Bill
  • Category II: Contains tax provisions not solely in Article 110 — can be introduced in either House; Rajya Sabha can amend

Constitutional Amendment Bills (Article 368)

  • Can be introduced in either House
  • Require special majority (2/3rd of members present and voting + majority of total membership)
  • Some provisions require ratification by at least half the State Legislatures

Stages of an Ordinary Bill

  1. Introduction (First Reading) — Title read; no discussion on merits
  2. Second Reading — General discussion on principles; referral to committee possible
  3. Committee Stage — Clause-by-clause examination
  4. Third Reading — Final vote; no amendments on principle, only verbal/drafting changes
  5. Transmission to Other House — Same three readings
  6. Presidential Assent (Article 111) — President can assent, withhold assent, or return for reconsideration (once)

Financial Committees

Financial oversight is Parliament's most critical function. Three major financial committees scrutinise government spending:

Public Accounts Committee (PAC)

FeatureDetail
Established1921 (under Montagu-Chelmsford reforms, Government of India Act 1919) — India's oldest parliamentary committee
Composition22 members (15 Lok Sabha + 7 Rajya Sabha); term: 1 year
ChairpersonBy convention, a member of the Opposition (since 1967, when Minoo Masani of the Swatantra Party became the first non-Congress chair of the PAC in the 4th Lok Sabha — establishing the convention)
FunctionExamines CAG audit reports to verify money was spent lawfully and for the purpose authorised by Parliament
ScopeExamines accounts relating to Railway, Defence, and other civil appropriation accounts

Estimates Committee

FeatureDetail
Established1950
Composition30 members, all from Lok Sabha (Money Bills are exclusively Lok Sabha's domain)
FunctionSuggests economies and improvements in the form of estimates; examines whether the policy implied in estimates is being implemented
LimitationCannot question the policy underlying estimates — only implementation

Committee on Public Undertakings

FeatureDetail
Established1964
Composition22 members (15 Lok Sabha + 7 Rajya Sabha)
FunctionExamines reports of CAG on public sector undertakings; assesses efficiency of PSU management

Departmentally Related Standing Committees (DRSCs)

DRSCs were introduced in 1993 (initially as 17 committees) and expanded to 24 committees to cover all central ministries and departments. They are joint committees of Parliament.

FeatureDetail
Number24 committees covering all Ministries/Departments
Servicing split16 serviced by the Lok Sabha Secretariat + 8 serviced by the Rajya Sabha Secretariat
CompositionEach has 31 members21 from Lok Sabha + 10 from Rajya Sabha
Term1 year
ChairpersonDRSCs serviced by LS Secretariat — chaired by Speaker's nominee. DRSCs serviced by RS Secretariat — chaired by Chairman's nominee
Functions(1) Examine Demands for Grants of ministries; (2) Examine Bills referred; (3) Consider policy documents/long-term plans; (4) Examine functioning of ministries under their purview
Pre-legislative roleDRSCs examine Bills before passage — technical scrutiny outside party politics
Bill referral rate (recent)17th Lok Sabha (2019-24): only ~16% of Bills referred — historic low; 18th Lok Sabha (2024–): ~26% (11 of 42 Bills referred through Winter 2025), partial recovery vs 17th LS but far below 14th–15th LS levels (60–71%)

Historical bill referral trend:

Lok SabhaReferral Rate
14th (2004-09)~60%
15th (2009-14)~71%
16th (2014-19)~27%
17th (2019-24)~16% (historic low)
18th (2024–)~26% (through Winter 2025)

DRSCs have been credited with improving legislative quality. However, bill referral rates remain far below the standards of the 14th–15th Lok Sabhas — a concern for deliberative quality.

Recent Developments (2024–2026)

Waqf (Amendment) Act, 2025 — Parliament, President, Supreme Court

A Joint Parliamentary Committee (JPC) chaired by Jagdambika Pal (BJP MP) was constituted in August 2024 to examine the Waqf (Amendment) Bill, 2024. The JPC submitted its report with dissent notes from Opposition members in early 2025. The Bill was re-introduced in the Budget Session on 2 April 2025, passed by Lok Sabha on 3 April 2025 (early hours, after 12-hour debate; 288 in favour, 232 against) and by Rajya Sabha on 4 April 2025 (128–95). President Murmu gave assent on 5 April 2025 — it became the Waqf (Amendment) Act, 2025, also rebranded as the UMEED Act (Unified Waqf Management, Empowerment, Efficiency and Development).

Over 65 petitions were filed in the Supreme Court challenging the Act. On 17 April 2025, the Supreme Court clubbed all petitions under In re: Waqf (Amendment) Act 2025 and issued an interim protective order: no waqf property (whether registered, unregistered, or waqf by user) was to be denotified, altered, or interfered with until the next hearing. On 15 September 2025, in its interim judgment, the Court (two-judge bench) stayed specific provisions — including Section 3(r) (the five-year practising-Muslim requirement before creating a waqf) and parts of Section 3C (government property "identified or declared" as waqf) — while declining to stay the Act in its entirety.

The substantive constitutional hearing on the Act's validity is ongoing as of April 2026.

UPSC angle: Prelims — Waqf Amendment Act 2025 passed April 2025; Presidential assent April 5, 2025; SC partial stay April 17, 2025. Mains — minority property rights vs regulatory reform; SC's use of separation of powers to stay an executive adjudication clause; JPC's role in scrutinising contentious legislation.

Parliament Suspension Record — Opposition Members Expelled (December 2023 and 2024)

In December 2023, 146 Opposition Members of Parliament were suspended from Parliament during the Winter Session — the largest mass suspension in Indian parliamentary history. The Opposition had sought a statement from the Home Minister on a security breach in the Lok Sabha gallery. In 2024, similar friction continued in Budget and Winter Sessions. These episodes have renewed debate about the role of the Speaker in maintaining order under Rule 374A and whether mass suspensions undermine the constitutional role of the Opposition.

UPSC angle: Prelims — December 2023 suspension; 146 MPs largest in history; Rule 374A. Mains — examine the constitutional implications of large-scale parliamentary suspensions; is the Speaker's power to suspend MPs subject to judicial review?

One Nation One Election — 129th Amendment Bill Referred to JPC (December 2024)

The Constitution (129th Amendment) Bill, 2024 was introduced in the Lok Sabha on 17 December 2024 and referred to a JPC for detailed examination. The Bill proposes simultaneous elections for Lok Sabha and all State Assemblies by amending Articles 83, 172, and 327. The Kovind High-Level Committee (constituted September 2023, submitted report 14 March 2024) had recommended this reform; the Union Cabinet accepted the recommendations on 18 September 2024.

The Bill requires ratification by at least half of the State Assemblies as a constitutional amendment under Article 368, making parliamentary procedure on this bill constitutionally complex.

UPSC angle: Prelims — 129th Amendment Bill, 2024; JPC referred; Kovind Committee (March 2024). Mains — what amendment procedure (under Article 368) is required for ONOE? How many states need to ratify? Evaluate the JPC's role in examining this landmark constitutional change.

Question Hour, Productivity & Committee Referrals — 18th Lok Sabha Data (2024–2025)

Session productivity (18th Lok Sabha):

SessionSittingsProductivity (LS)Bills Passed
Inaugural Session (June 2024)3
Budget Session 202423
Monsoon Session 202415 (115 hours)136%4
Winter Session 202420 (26 days)54.5%4 (LS)
Budget Session 202526 (160 hrs)118%16
Winter Session 2025158

Note: Productivity above 100% indicates extended sittings (beyond scheduled hours); below 100% indicates adjournments/disruptions cutting into scheduled time.

Winter 2024's 54.5% productivity reflected significant disruptions over Adani-Hindenburg controversy and Manipur; Winter 2025's 15 sittings reflected disruptions over Waqf judgment implementation and delimitation controversy.

Bill referral rate (18th LS): ~26% (11 of 42 Bills referred through Winter 2025) — improved over 17th LS's 16%, but far below 14th–15th LS averages of 60–71%. Notable committee referrals: Waqf Bill (JPC, Jagdambika Pal), ONOE Bills (JPC), Corporate Laws Amendment Bill (JPC, Budget Session 2026).

Question Hour disruptions: The Rajya Sabha Chairman and Lok Sabha Speaker both noted in 2024 that Question Hour was being disrupted almost daily. In the Monsoon Session 2024, only about 50% of listed questions could actually be answered due to disruptions. Budget Session 2025 saw 134 starred questions answered orally; 691 Zero Hour matters raised.

UPSC angle: Prelims — Question Hour (Rules 32-54, LS); Zero Hour (12:00–1:00 PM, Indian innovation 1962, not in Rules); 18th LS productivity data (Monsoon 2024 = 136%; Winter 2024 = 54.5%); bill referral rate 18th LS ~26% vs 17th LS 16%. Mains — assess Question Hour's effectiveness in ensuring ministerial accountability in the 18th Lok Sabha; evaluate whether declining committee referral rates indicate a weakening of parliamentary deliberation.

One Nation One Election — JPC Gets Extension; Work Continues (2025–2026)

The 39-member JPC examining the Constitution (129th Amendment) Bill, 2024 (ONOE) received successive deadline extensions. In August 2025, Lok Sabha extended the JPC's tenure to allow it to submit its report by the first day of the last week of the Winter Session 2025. However, the committee had not finalised its report by that deadline. A further extension was granted, with the deadline moved to the 2026 Monsoon Session.

The JPC, chaired by BJP MP P.P. Chaudhary, held extensive consultations with experts, state governments, former Chief Election Commissioners, and constitutional scholars. The committee's deliberations revealed deep disagreements among states and Opposition parties about ONOE's implications for federalism and State Assembly autonomy. As of April 2026, the JPC report has not been tabled; the Bill awaits committee clearance before being scheduled for floor votes.

UPSC angle: Prelims — ONOE JPC: extended to Monsoon Session 2026; PP Chaudhary (JPC Chair); 129th Amendment Bill 2024. Mains — what does the JPC's prolonged examination reveal about parliamentary committee processes in India? Is the ONOE Bill's extensive JPC scrutiny a sign of robust legislative deliberation or political delay?

Election Reforms Discussion in Parliament — Winter Session 2025

A focused discussion on Election Reforms was held in both Houses during the Winter Session 2025 (Lok Sabha: December 9–10; Rajya Sabha: December 11, 15, 16). Key themes debated: electoral roll quality and the Election Commission's Special Intensive Revision (SIR) drive; the One Nation One Election framework; criminalization of politics and the case for lifetime bans; and the constitutional status of the Election Commission's independence (vis-à-vis the CEC & ECs Act 2023). This was a rare dedicated parliamentary discussion on electoral governance — a sign of rising political salience of the ONOE and delimitation debates.

UPSC angle: Prelims — Winter Session 2025: dedicated Election Reforms discussion in both Houses (December 9–16). Mains — evaluate the adequacy of India's current electoral reform framework; should parliamentary discussions on electoral issues translate into specific legislative proposals?


Recent Reforms

Budget Presentation Advanced (2017) The Government advanced the Union Budget presentation from end-February (Feb 28) to February 1 beginning with the Union Budget 2017-18 (presented on 1 February 2017 by FM Arun Jaitley — note: the 2017 Budget was actually presented on 2 Feb 2017 as 1 Feb fell on Wednesday during a State election period; subsequent Budgets have been on Feb 1). The advance allows completion of the budget process and passage of Appropriation Bill before the start of the new financial year (1 April) — enabling the government to begin spending from 1 April instead of waiting until June.

Merger of Railway Budget with Union Budget (2017) The separate Railway Budget had been presented since 1924 (Acworth Committee 1920–21 recommendation; formalised by Railway Convention 1924). Following the recommendation of the Bibek Debroy Committee (Member, NITI Aayog; report submitted June 2015; supported by Bibek Debroy + Kishore Desai's separate paper "Dispensing with the Railway Budget"), the Union Cabinet approved the merger on 21 September 2016, and from Union Budget 2017-18 the Railway Budget has been part of the general budget. Railways now receive Gross Budgetary Support from the Centre.

Parliamentary Budget Office (PBO) The idea of a Parliamentary Budget Office (on lines of the US Congressional Budget Office) has been proposed to provide Parliament with independent economic and fiscal analysis to improve budget scrutiny.


Rajya Sabha's Role in the Federal Structure

The Rajya Sabha represents States in the Union legislature. Its special powers include:

  • Article 249 — By 2/3rd majority, can authorise Parliament to legislate on a State subject in the national interest
  • Article 312 — By 2/3rd majority, can authorise creation of new All-India Services
  • Rajya Sabha cannot be dissolved; one-third retires every 2 years (each member serves 6 years)
  • Equal powers with Lok Sabha on all non-money, non-confidence matters, including ordinary legislation and constitutional amendments

Lame Duck Session

The last session of the existing Lok Sabha before its dissolution is called a Lame Duck Session. MPs who lost re-election (or who are not contesting again) attend this session but with reduced legitimacy — hence the name. The session typically only conducts essential business; major legislation is rare.

Parliamentary Forums

Eight Parliamentary Forums exist to enable cross-party informal discussion on specific themes, chaired by the Speaker (or Vice-President for the RS-led one):

  • Forum on Population & Public Health
  • Forum on Children
  • Forum on Disaster Management
  • Forum on Disability
  • Forum on Artisans & Craftspeople
  • Forum on Millennium Development Goals (now SDGs)
  • Forum on Global Warming and Climate Change
  • Forum on Water Conservation & Management

These are not committees but discussion platforms; they have no formal decision-making power.

High-Yield Confusion Pairs (Rule C)

PairKey distinction
Adjournment / Adj Sine Die / Prorogation / DissolutionAdjournment: presiding officer; sitting suspended; business survives. Adj Sine Die: indefinite, no fixed date. Prorogation: President; ends session; Bills survive (motions lapse). Dissolution: President; ends LS; LS-pending Bills lapse; RS-only Bills survive
Starred vs Unstarred QuestionStarred: oral, supplementary allowed, 20/day. Unstarred: written, no supplementary, 230/day. Both need 15-day notice
Question Hour vs Zero HourQH: 11 AM–12 PM, formal, in Rules, 15-day notice. ZH: 12 PM–1 PM, informal, NOT in Rules, Indian innovation 1962, no notice
Rule 184 vs Rule 193 Discussion184: WITH formal motion + voting. 193: WITHOUT motion or vote — short-duration
Cut MotionsDisapproval Policy Cut (₹1) vs Economy Cut (specific reduction) vs Token Cut (₹100)
Voice Vote vs Division vs Secret BallotVoice: default. Division: recorded individual vote. Secret: Speaker/Deputy Speaker election + Presidential impeachment
Whip (1/2/3-line)1-line: informational. 2-line: must be present. 3-line: must vote per party direction; defiance = anti-defection trigger
Statutory ResolutionRequired by specific statute (e.g., Emergency proclamation approval). Different from ordinary Government/Private Member Resolution
Closure typesSimple, Compartments, Kangaroo (skip clauses), Guillotine (cut debate, all remaining items voted)
PAC vs Estimates vs COPUPAC 22 (15+7), Opposition chair since 1967, oldest 1921. Estimates 30 (LS only — largest). COPU 22 (15+7), examines PSUs
DRSC composition24 committees, 31 each (21 LS + 10 RS); 16 LS Sec + 8 RS Sec

Exam Strategy Note: For Mains, the significance of parliamentary committees (especially DRSCs) in strengthening legislative oversight is a recurring theme. Link PAC's work with CAG accountability for GS2. For Prelims, remember the exact membership numbers and which committees are exclusively Lok Sabha (Estimates Committee — only one with no Rajya Sabha members).
