The Indian Polity Parliamentary System is the single most scoring static segment of UPSC GS Paper 2 — and yet over 60% of aspirants in the 2025 attempt cycle reported losing 8–12 marks here on basic procedural questions like joint sittings, money bill certification and the anti-defection law. This 2027-aligned guide consolidates Articles 79 to 122 with landmark cases, recent amendments (104th Amendment, 2019), and 10 prelims-grade MCQs at the end. Read it once and you have a permanent revision crutch for both Prelims (5–7 marks) and Mains (one full sub-question almost every year).
Why the Parliamentary System Matters in UPSC GS2 (2027 Pattern)
UPSC has steadily increased weightage for “Functioning of Parliament” since 2019, with at least one Mains question every year between 2020–2025. Topics like privileges of Members, role of the Speaker, productivity of recent sessions, and standing committees are now compulsory reading. The UPSC 2027 strategy hub on Civils Gyani tracks these year-on-year trends.
Composition of Parliament — Articles 79 to 88
Article 79 declares Parliament to consist of the President + Council of States (Rajya Sabha) + House of the People (Lok Sabha). The Lok Sabha currently has 543 elected members (max strength 550 under Article 81; Anglo-Indian seats abolished by the 104th Amendment, 2019). The Rajya Sabha has 245 members (max 250 under Article 80) — 233 elected by State Legislative Assemblies via Single Transferable Vote and 12 nominated by the President for distinguished services in literature, science, art, and social service.
Lok Sabha vs Rajya Sabha — Comparison Table
| Feature | Lok Sabha | Rajya Sabha |
|---|---|---|
| Constitutional Article | Article 81 | Article 80 |
| Maximum Strength | 550 (530 States + 20 UTs) | 250 (238 elected + 12 nominated) |
| Current Strength | 543 | 245 |
| Tenure | 5 years (dissolvable) | Permanent body, 1/3rd retire every 2 years |
| Money Bill | Originates here only | Cannot amend, only recommend; 14-day delay |
| No-Confidence Motion | Only here (Rule 198) | Cannot be moved |
| Election Method | Direct, FPTP | Indirect, STV by State MLAs |
| Presiding Officer | Speaker | Vice-President (ex-officio Chairman) |
| Special Powers | Originate Money Bills, Demand Grants | Article 249 (legislate on State List), Article 312 (create AIS) |
Legislative Procedure — Ordinary Bill, Money Bill and Constitutional Amendment Bill
An Ordinary Bill can originate in either House, requires simple majority and goes through three readings. If the second House rejects it, returns it amended, or doesn’t act for 6 months, the President may summon a Joint Sitting under Article 108 presided over by the Speaker. Only three joint sittings have occurred since 1950 (1961 Dowry Prohibition, 1978 Banking Service Commission, 2002 POTA).
A Money Bill (Article 110) deals exclusively with imposition/abolition of taxes, government borrowing, custody of Consolidated Fund, etc. Critically, the Speaker’s certification is final (Article 110(3)) — though the Aadhaar judgment (2018) hinted at limited judicial review. Rajya Sabha can only suggest amendments which the Lok Sabha may accept or reject; maximum delay is 14 days.
A Constitutional Amendment Bill under Article 368 requires a majority of total membership of each House plus a 2/3 majority of members present and voting. For amendments affecting federal provisions (e.g. Articles 54, 55, 73, 162, 241, 7th Schedule), ratification by at least half the State Legislatures is also needed.
Parliamentary Procedures — Question Hour, Zero Hour, Adjournment and Censure
Question Hour (first hour of every sitting, 11 AM to 12 noon) allows MPs to extract information from the executive — Starred (oral, supplementaries allowed), Unstarred (written), Short-Notice. Zero Hour (12 noon onwards) is an Indian innovation since 1962 — members raise matters of urgent public importance without prior notice. Calling Attention Motion (Rule 197) and Adjournment Motion (extraordinary device causing censure) are weapons of opposition. A No-Confidence Motion requires 50 members’ backing under Rule 198 — historically rare (only 27 since 1952; Modi government won the last one in July 2018, 325-126).
Anti-Defection Law — Tenth Schedule
Inserted by the 52nd Amendment, 1985, the Tenth Schedule disqualifies any MP/MLA who voluntarily gives up party membership or votes against the party whip. Originally one-third defection was protected; the 91st Amendment, 2003 raised this to two-thirds (merger only). The Speaker/Chairman is the deciding authority (Kihoto Hollohan, 1992 — subject to judicial review). Recent SC observations (Maharashtra crisis, 2023) have urged Parliament to consider transferring this jurisdiction to a permanent neutral tribunal.
Parliamentary Committees — The Real Workhorses
Of the 250+ Bills in the 17th Lok Sabha, fewer than 25% were referred to committees — a sharp drop from 71% in the 15th. The 24 Department-Related Standing Committees (DRSCs), instituted in 1993, scrutinise Bills, Demands for Grants, and Annual Reports. Financial committees include Public Accounts Committee (chaired by Opposition), Estimates Committee, and Committee on Public Undertakings.

Mains Answer-Writing Approach (10/15-marker)
- Introduction (50 words): Quote the Article + a recent data point (e.g., 17th Lok Sabha productivity 88%; bills passed without referral — 35%).
- Body (paragraphs): Use sub-headings — Constitutional Provisions, Operational Reality, Issues, Reforms (NCRWC 2002, 2nd ARC, recent SC verdicts).
- Way Forward: Cite specific reform — committee referral floor, anti-defection neutral tribunal, productivity index, DRSC strengthening.
- Conclusion: Tie back to Article 79 / Basic Structure / Parliamentary Sovereignty.

Frequently Asked Questions
Q1. What is the difference between adjournment, prorogation and dissolution of Lok Sabha?
Adjournment ends a sitting; prorogation ends a session (by the President under Article 85); dissolution ends the life of Lok Sabha itself (only Lok Sabha can be dissolved — Rajya Sabha is permanent).
Q2. Can the same Bill be reintroduced after being defeated in Parliament?
An Ordinary Bill defeated in either House can be reintroduced in the same session only with the Speaker’s permission; otherwise in the next session. A Money Bill rejected in the Rajya Sabha is deemed passed if Lok Sabha doesn’t accept the recommendations within 14 days.
Q3. What is the Whip system in Parliament?
A Whip is a written directive issued by a political party to its members to vote in a particular manner. Defying a 3-line whip can attract disqualification under the Tenth Schedule (anti-defection law).
Q4. How many sessions of Parliament are held in a year?
Conventionally three — Budget (Feb-May), Monsoon (Jul-Aug), Winter (Nov-Dec). Constitutionally (Article 85), the gap between two sessions cannot exceed 6 months — sessions per year are not fixed by the Constitution.
Q5. What is the role of the Vice-President in Parliament?
The Vice-President is the ex-officio Chairman of the Rajya Sabha (Article 64). He/she presides over its proceedings, but can vote only in the case of an equality of votes (casting vote).
