Majorities in Parliament: the arithmetic

Detail

Two words to know first

• Total membership means the full number of seats in a House. Empty seats and absent members still count [3][4].
• Present and voting means members who vote "Aye" or "No". A member who abstains (stays in the House but does not vote either way) is not counted as present and voting [3][4].
• Effective strength means total membership minus vacant seats.
• Quorum is the smallest number of members who must be present before the House can sit. It is one-tenth of the total number of members (Art. 100(3)) [6]. Quorum is about whether the House can sit at all. It is not a kind of majority.

The four majorities

Majority	How it is counted	Lok Sabha figure	Used for
Simple majority	More than half of members present and voting	Changes with every vote (247 vote, so 124 needed)	Ordinary bills, money bills, most motions and resolutions, election of the Speaker, Deputy Speaker and Deputy Chairman, laws under Art. 4 (new states, changing state boundaries) and Art. 169 (creating or abolishing a Legislative Council)
Absolute majority	More than half of total membership	272 of 543	Forming a government; it is also the first test of the Art. 368 special majority
Effective majority	More than half of effective strength (total minus vacancies)	Example: 543 − 3 vacancies = 540, so 271 needed	Removing the Vice-President (Art. 67(b)), the Speaker or Deputy Speaker (Art. 94(c)), the Rajya Sabha Deputy Chairman (Art. 90(c)), and the Speaker, Deputy Speaker, Chairman or Deputy Chairman of a state legislature (Art. 179(c), Art. 183(c))
Special majority	Three kinds (see below)	—	Constitutional amendments, emergency approval, removing judges, impeaching the President and others

• Simple majority. More than half of the members who actually vote.
• NCERT example: if 247 members vote, 124 votes are needed.
• This is the "normal" majority. Most work in Parliament is done this way.

• Art. 4 and Art. 169 laws change the Constitution's text. They still need only a simple majority, and they are not treated as amendments under Art. 368.

• Absolute majority. More than half of all seats, whether or not members turn up to vote.

• A party or coalition needs 272 seats in the Lok Sabha to form a government on its own strength.

• Effective majority. More than half of the members actually in office at that time.

• The Constitution words it as "a majority of all the then members of the House".
• Art. 67(b): the Rajya Sabha removes the Vice-President by an effective majority. The Lok Sabha then only has to agree to the resolution, and a simple majority is enough for that. This is a common exam trap.

Special majority: three kinds

Kind	Formula	Used for
(a) Art. 368 type	Majority of total membership and at least two-thirds of those present and voting, in each House separately	Constitutional amendments (Art. 368(2)); approving a national emergency (Art. 352(6), added by the 44th Amendment, 1978); removing a Supreme Court or High Court judge (Art. 124(4), Art. 218); removing the Chief Election Commissioner (Art. 324(5))
(b) Two-thirds of present and voting	At least two-thirds of the members who vote	Rajya Sabha resolution letting Parliament make laws on a State List subject in the national interest (Art. 249) [8]; Rajya Sabha resolution to create a new All India Service (Art. 312) [5]
(c) Two-thirds of total membership	At least two-thirds of all seats, counting vacancies	Impeaching the President (Art. 61). Each House must pass the resolution by this majority [9]

• Art. 368 wording. An amendment bill can start in either House. Each House must pass it "by a majority of the total membership of that House and by a majority of not less than two-thirds of the members of that House present and voting". Then it goes to the President for assent [2].
• Every stage needs it. In Parliament's practice, the two-thirds test applies at all effective stages of the bill, including voting on each clause. It is not applied only at the final vote [4].
• No joint sitting. A joint sitting (both Houses meeting together to settle a disagreement, Art. 108) is not available for amendment bills. If either House rejects the bill, it fails [5].
• States in some cases. If the amendment touches federal provisions, it also needs ratification by the legislatures of at least half the states, by simple majority (proviso to Art. 368(2)) [5].

Steps for an Art. 368 amendment, and the majority each step needs

Step	What happens	Majority or condition
1	Bill introduced in either House by a minister or a private member	No prior permission of the President is needed
2	Passed in House 1	Special majority at every effective stage [4]
3	Passed in House 2	Special majority, separately; no joint sitting [5]
4	Ratification by states (only for federal provisions)	At least half the states, by simple majority [5]
5	President's assent	The President must give assent (made binding by the 24th Amendment, 1971) [2]

Worked examples: updating NCERT

• Lok Sabha size today. Total membership is 543. NCERT gives 545, which needed 273.
• Art. 81 allows up to 530 members from the states and up to 20 from the Union Territories [6].
• The President could also nominate up to 2 Anglo-Indian members under Art. 331. This seat rule was due to end on 25 January 2020, after 70 years [7].
• The 104th Amendment Act, 2019 came into force on 25 January 2020. It extended SC/ST seat reservation for 10 more years, to 25 January 2030, but did not extend Anglo-Indian nomination [7]. No Anglo-Indian member was nominated to the 17th Lok Sabha [6].

• Result: 543 seats, so at least 272 votes are needed (NCERT: 545 members, at least 273).

• NCERT's question: 400 members vote in the Lok Sabha.

• Two-thirds of 400 = 266.67, so 267 votes are needed.
• Majority of total membership = more than half of 543, so 272 votes are needed.

• The bill must pass both tests, so the answer is the higher number: 272.

• Other turnouts (Lok Sabha, 543 seats):

Members present and voting	Two-thirds test	Total-membership test	Votes needed
300	200	272	272
400	267	272	272
408	272	272	272
450	300	272	300
543 (everyone votes)	362	272	362

• Rule of thumb: if 408 or fewer members vote, the total-membership test decides. If more members vote, the two-thirds test decides.

• Rajya Sabha. The present strength is 245: 233 elected by state and UT legislatures, and 12 nominated by the President [5]. More than half of 245 = 123. If all 245 vote, two-thirds = 164 (verify current strength before the exam).

Why a special majority?

• A thin majority is enough for ordinary work. A ruling party with just over half the seats can pass ordinary laws and the budget on its own.
• It is not enough to change the Constitution.
• The party must reach two-thirds of those voting.
• So it usually has to win over some opposition parties.

• The result is that amendments rest on broad agreement across parties, not on the will of one party.

• The NCERT cartoon asks, "Is it politics or maths?" The answer is both. The numbers force political bargaining.

• Flexible but not too easy. Ambedkar argued in the Constituent Assembly that the Constitution should be neither as rigid as the American one nor as easy to change as an ordinary law. A special majority in Parliament sits between the two. State ratification is added only where federal provisions are touched.
• The limit of arithmetic. In the 1970s, governments with two-thirds majorities passed sweeping changes, such as the 42nd Amendment (1976). The Supreme Court had already held in Kesavananda Bharati v. State of Kerala (1973) that even a valid special majority cannot destroy the basic structure (the core features of the Constitution, such as democracy, federalism and judicial review). Numbers decide how an amendment passes. The basic structure decides what it can change.

Prelims Hooks

• Art. 368 special majority = majority of total membership + two-thirds of present and voting, in each House separately. There is no joint sitting for amendment bills.
• Abstentions are not counted in "present and voting". Vacancies are counted in "total membership".
• Two-thirds of total membership is needed only to impeach the President (Art. 61). Do not confuse this with the Art. 368 formula.
• Arts. 249 and 312: Rajya Sabha resolution by two-thirds of members present and voting. Only the Rajya Sabha passes these.
• Effective majority ("all the then members"): VP removal (Art. 67(b), Rajya Sabha), Speaker or Deputy Speaker removal (Art. 94(c)), Deputy Chairman removal (Art. 90(c)), state presiding officers (Art. 179(c)).
• Art. 4 and Art. 169 laws need only a simple majority. They are not Art. 368 amendments.
• National emergency approval (Art. 352(6)) needs a special majority. This came with the 44th Amendment, 1978. Before it, a simple majority was enough.
• 104th Amendment, 2019 (in force from 25 January 2020): ended Anglo-Indian nomination and extended SC/ST reservation to 2030. Lok Sabha strength is 543 and the amendment threshold is 272 (NCERT: 545 and 273).
• In the Lok Sabha, if 400 vote, the answer is 272, not 267. If all 543 vote, the answer is 362.
• Rajya Sabha: 245 members (233 elected + 12 nominated). A majority of total membership is 123.

Mains Points

• Consensus as a safeguard. The double test, one based on total seats and one based on votes cast, stops a thin or thinly attended majority from changing the Constitution. Amendments then need agreement across parties, and federal changes also need the states (proviso to Art. 368(2)).
• Flexible yet stable. India's method avoids the rigidity of the US Constitution, which has 27 amendments in over 230 years. India has passed 106 amendments by 2023. Critics say the large majorities of 1971–76 made amendment too easy. That is why the basic structure doctrine (1973) acts as a check that arithmetic alone cannot override.
• Which majority for which office. The Constitution sets a harder test for more serious acts. Electing a presiding officer needs a simple majority. Removing one needs an effective majority. Removing a judge or the CEC needs a special majority. Impeaching the President needs two-thirds of total membership. This scale protects independent offices from removal by a passing majority.
• Reform debate. Some suggest wider ratification by the states, or a referendum for changes to core features. Others argue that the Rajya Sabha's equal role, and the coalition politics of 1989–2014, already force consensus without extra steps.
