The Indian Constitution is neither rigidly unamendable like the old British common law nor so flexible that Parliament can rewrite it overnight. It sits in the middle — what constitutional scholars call a "semi-rigid" document — and Article 368 is the gate through which all changes must pass.
Here's the mental model: think of the Constitution as a three-layer cake. The top layer (certain federal provisions) needs both Parliament and the states to agree before anything changes. The middle layer (most major provisions) needs Parliament alone, but with a special super-majority. The bottom layer (a handful of procedural matters) can be changed by a simple majority, just like passing an ordinary law.
Why does this matter for your exam? Because Bihar Police Constable papers are not interested in you reciting constitutional theory. They want you to link an amendment number to what it actually did — "42nd amendment added 'Secular' to the Preamble", "56th amendment gave Goa statehood", "92nd amendment added four languages to the Eighth Schedule". That pattern of question-type has repeated year after year.
The analogy that works best: imagine the Constitution as a rented house with three kinds of walls. Ordinary interior walls you can knock down alone (simple majority). Load-bearing walls need a structural engineer's approval (special majority). And walls shared with the neighbour's house need the neighbour's consent too (state ratification). Article 368 is the building code that tells you which wall is which.
One more thing to carry into the exam hall — the amendment process itself has been amended. The 42nd Amendment (1976) tried to make Parliament's amending power absolute. The 44th Amendment (1978) walked much of that back. The Supreme Court in Kesavananda Bharati (1973) drew the line with the Basic Structure doctrine — Parliament can amend the Constitution but cannot destroy its essential character. You won't be asked to argue the doctrine, but you will be asked which amendment was associated with which shift.
Article 368 lays down both the power to amend and the procedure for doing so. A bill to amend the Constitution can be introduced only in either House of Parliament (not in state legislatures). It must be passed in each House separately — joint sessions are not allowed for constitutional amendment bills. This is unlike ordinary legislation, where a deadlock between the two Houses can be resolved by a joint sitting.
Three types of majority requirements:
| Type | Requirement | Examples | |---|---|---| | Simple majority (> 50% of members present and voting) | Ordinary legislative process | Admission of new states, creation of new states, Second Schedule changes | | Special majority | 2/3rd of members present and voting AND majority of total membership of each House | Most fundamental rights, DPSP, amendment procedure itself | | Special majority + State ratification (by at least half the state legislatures) | Provisions touching federal structure | Election of President, extent of executive power of Union and states, Supreme Court, High Courts, representation of states in Parliament, Article 368 itself |
There is no time limit prescribed for state legislatures to ratify. And once a state ratifies, it cannot withdraw consent — though this has never been tested in practice.
42nd Amendment, 1976 — "Mini-Constitution" Called the most controversial amendment in Indian history, this was enacted during the Emergency. It added "Socialist", "Secular", and "Integrity" to the Preamble. It also curtailed judicial review, gave Parliament overriding power over Fundamental Rights in many areas, added Fundamental Duties (Part IVA, Article 51A), and extended the term of Lok Sabha and state assemblies from 5 to 6 years. The word count of the Constitution increased dramatically — which is why some call it a "mini-constitution."
44th Amendment, 1978 — Course Correction After the Emergency ended and the Janata Party came to power, the 44th Amendment reversed several 42nd Amendment changes. It restored the original 5-year term of Lok Sabha. It removed the Right to Property from Fundamental Rights (Article 19(1)(f) and Article 31) and converted it to a legal right under Article 300A. It strengthened protections against proclamation of Emergency — the President can now proclaim Emergency only on the written advice of the Cabinet.
73rd Amendment, 1992 — Panchayati Raj Added Part IX and the Eleventh Schedule to the Constitution. Made Panchayati Raj institutions constitutional bodies. Mandated elections every five years, reservation for SC/ST and women (not less than one-third of seats), and creation of State Finance Commissions and State Election Commissions.
74th Amendment, 1992 — Urban Local Bodies Added Part IX-A and the Twelfth Schedule. Did for urban local bodies (municipalities, municipal corporations, town area committees) what the 73rd did for rural areas. Introduced the concept of "Wards Committees" for larger urban bodies.
56th Amendment, 1987 — Goa's Statehood Granted full statehood to Goa, making it the 25th state of India. Daman and Diu remained a separate Union Territory.
86th Amendment, 2002 — Right to Education Added Article 21A, making free and compulsory education for children aged 6-14 a Fundamental Right. Also amended Article 45 (Directive Principles) and Article 51A (Fundamental Duties).
92nd Amendment, 2003 — Four New Languages Added Bodo, Dogri, Maithili, and Santhali to the Eighth Schedule. This took the number of Scheduled Languages from 18 to 22. Note for Bihar candidates: Maithili — a language with deep roots in Bihar — was added through this amendment.
93rd Amendment, 2005 — OBC Reservation in Education Added clause (5) to Article 15, enabling states to make special provisions for the advancement of socially and educationally backward classes (OBCs) and SC/ST in admission to educational institutions, including private unaided institutions (but not minority educational institutions).
101st Amendment, 2016 — GST Introduced the Goods and Services Tax, creating a new Article 246A (concurrent power to legislate on GST), and established the GST Council.
103rd Amendment, 2019 — 10% EWS Reservation Added clauses (6) to Articles 15 and 16, enabling reservation for the Economically Weaker Sections (EWS) up to 10% in education and public employment.
Treat the 42nd and 44th amendments as a matched pair — one pushed powers toward Parliament (Emergency-era, 1976), the other pulled back (post-Emergency correction, 1978). If a question says "which amendment removed the Right to Property from Fundamental Rights," the answer is 44th, not 42nd. The 44th moved, the 42nd did not touch property rights. Memorise: 42 = ADD (added Socialist, Secular, Integrity to Preamble); 44 = REMOVE (removed Right to Property from FR list). Standard recall: 30 seconds of scanning options. With this pair-logic: under 8 seconds.
73 = 7+3 = ten letters in "PANCHAYATI" (count: P-A-N-C-H-A-Y-A-T-I = 10). Rural = Panchayat = 73rd. 74 = one more = one step up = Urban. So: 73 → Rural (Panchayat), 74 → Urban (Municipality). Questions that ask "which amendment constitutionalised urban local bodies" — go straight to 74. Step count: 1 mental check vs. scanning through memory.
The four languages added by the 92nd Amendment: Bodo, Dogri, Maithili, Santhali. Remember the code BDMS — "Bihar Deserves Maithili Status" works especially well for Bihar exam context, since Maithili is the language of Mithila region in Bihar. This turns a list-recall question into a 3-second code lookup instead of a 20-second list scan.
Article 15(4) was inserted by the 1st Amendment (1951) and covers SC/ST and socially/educationally backward classes in general. Article 15(5), added by the 93rd Amendment (2005), specifically extends this to private unaided educational institutions (except minority institutions). Exam questions often ask "which article enables OBC reservation in private colleges" — the answer is 15(5), not 15(4). Mental check: 5 > 4, private colleges are a more recent/expanded scope. One comparison step vs. searching memory without anchor.
The original Preamble (1949) had: Sovereign, Democratic, Republic, Justice, Liberty, Equality, Fraternity. The 42nd Amendment (1976) inserted three words: Socialist, Secular, Integrity. In MCQ options, if the question asks "what was NOT added by the 42nd Amendment to the Preamble," eliminate Socialist, Secular, Integrity — whatever remains is your answer. This elimination takes 4 steps. Without this, students often confuse "Republic" (original) with "Secular" (added later). Eliminates wrong choices in under 10 seconds.
When you see a constitutional amendment question in the Bihar Police Constable paper, run this mental decision tree in sequence:
Step 1 — Is it asking about a specific amendment number? Yes: Map the number to its known keyword (42 = Secular/Socialist, 44 = Property Right removed, 56 = Goa, 73 = Panchayat, 74 = Urban, 86 = RTE, 92 = BDMS languages, 93 = Article 15(5), 101 = GST, 103 = EWS).
Step 2 — Is it asking which amendment did a specific thing? Identify the policy domain: Language → 92nd. Panchayat → 73rd. Education OBC → 93rd. Emergency correction → 44th. Preamble words → 42nd. Goa statehood → 56th. Work backwards from domain to number.
Step 3 — Is it asking about the procedure (Article 368)? Check: simple majority (trivial changes), special majority (most amendments), special majority + state ratification (federal structure). The trap here is assuming all amendments need state ratification — they don't.
Step 4 — Elimination when unsure. Cross out options you can definitively rule out. Even eliminating one option shifts probability. Don't leave amendment questions blank — they are straightforward recall with high accuracy potential if you've built the right lookup table.
Total time budget per question: 20-30 seconds.
Why this question: The 92nd Amendment is a recurring favourite because it touches Maithili — directly relevant to Bihar — and tests whether candidates know the exact count of languages added.
Solving path: Apply the BDMS code — Bodo, Dogri, Maithili, Santhali. Count: that is exactly 4 languages. The correct answer is (B) 4. Common distractor is option (A) 5 — candidates confuse this with the total languages sometimes associated with a different amendment. The BDMS code eliminates any ambiguity in 3 seconds.
Why this question: The 93rd Amendment question tests a precise constitutional detail — which specific clause was added to which article. This is the kind of question that separates prepared candidates from those who only remember broad strokes.
Solving path: The 93rd Amendment specifically targeted educational institutions and OBC reservation. It added clause (5) to Article 15 (Right against Discrimination), not Article 16 (Equal Opportunity in Public Employment). Remember: education discrimination → Article 15. Employment opportunity → Article 16. The exam trap is picking Article 16, which governs reservation in jobs, not college admissions. Correct answer: Article 15.
Why this question: Goa's statehood is a clean factual question with a specific amendment number (56th) that many candidates confuse with nearby numbers like 55th or 57th.
Solving path: The 56th Constitutional Amendment Act, 1987 granted statehood to Goa — making it the 25th state. Daman and Diu stayed a Union Territory. Anchor this: 5+6 = 11, Goa has 11 districts (this is approximate and a memory aid, not a strict fact — use the BDMS-style anchoring if you prefer: "56 = Goa Goes State"). Eliminate 70th, 71st, 72nd — these deal with other reorganisation and language matters. Correct answer: 56th Amendment.
Why this question: The 42nd Amendment and the Preamble question appears in almost every batch of Bihar and UP Police papers. It tests recall of specific words added, not just the amendment number.
Solving path: The 42nd Amendment (1976) added three words to the Preamble: Socialist, Secular, Integrity. The question asks which feature was added — the correct answer is "Secular" (धर्मनिरपेक्षता). The trap options are "Republic" (गणराज्य) and "Sovereignty" (समप्रभुता) — both were in the original Preamble of 1949. Eliminate those immediately. "Secret ballot" (गुप्त मतदान) is not a Preamble concept at all. That leaves only "Secular." Correct answer: धर्मनिरपेक्षता / Secular.
Confusing 42nd and 44th on the Right to Property. The 42nd Amendment did not remove the Right to Property. The 44th Amendment (1978) removed it from Fundamental Rights (Article 19 and 31) and placed it as a constitutional right under Article 300A. Do not flip these two.
Assuming all amendments require state ratification. Only amendments that affect the federal structure need ratification by at least half the state legislatures. Most amendments — including major ones like the 42nd and 44th — needed only a special majority in Parliament. Many candidates over-apply the ratification rule.
Getting the count of Eighth Schedule languages wrong. Before the 92nd Amendment: 18 languages. After: 22 languages (4 added). The number 22 is the current count — this is what the exam will ask. Don't say 21 or 24.
Mixing up 73rd and 74th Amendments on the content. The 73rd added the Eleventh Schedule (29 subjects for Panchayats). The 74th added the Twelfth Schedule (18 subjects for Municipalities). Questions sometimes quote the schedule number and ask for the amendment — reverse-map using the 73/74 rural/urban anchor.
Thinking the Preamble cannot be amended. The Supreme Court in the Kesavananda Bharati case held that the Preamble is part of the Constitution and can be amended — but the Basic Structure cannot be destroyed. The 42nd Amendment's changes to the Preamble have been upheld. Do not state "the Preamble cannot be amended" in any answer context.
Confusing Article 15(4) and Article 15(5) for OBC reservation. Article 15(4) was inserted by the 1st Amendment for SC/ST/backward classes in general (mainly state-run institutions). Article 15(5), inserted by the 93rd Amendment, extended this specifically to private unaided educational institutions. Exam questions have asked this distinction directly.
