A Glimpse of Amendments to Indian Constitution

The Constitution of India came into force on the 26th of January 1950 — a document that its principal architect, Dr. B.R. Ambedkar, described as both rigid and flexible, capable of being adapted to the needs of a living, changing nation. Over seven decades, Parliament has exercised its constituent power under Article 368 no fewer than a hundred and six times. Each amendment tells a story — of political necessity, judicial pushback, social reform, or territorial integration. Together, they chronicle how the Republic has navigated the complex tensions between individual rights, state authority, and the ambitions of a developing democracy.

The First Amendment Act, 1951

The ink had barely dried on the Constitution before Parliament found it necessary to amend it. Enacted on 18 June 1951, the First Amendment was both sweeping and controversial. Its immediate trigger was the Supreme Court's judgment in State of Madras v. Champakam Dorairajan (AIR 1951 SC 226), which struck down the Communal Government Order reserving seats in state medical and engineering colleges on the ground that it violated the right to equality under Article 15. Parliament responded by inserting clause (4) to Article 15, empowering the State to make special provisions for the advancement of socially and educationally backward classes of citizens and for Scheduled Castes and Scheduled Tribes.

In the same breath, three additional grounds — public order, friendly relations with foreign states, and incitement to an offence — were added to the restrictions on the freedom of speech and expression under Article 19(2), partly to neutralise the Allahabad High Court's judgment in Motilal v. State of Uttar Pradesh (AIR 1951 All 257). Articles 31A and 31B were inserted to protect land reform laws from fundamental rights challenges, and the Ninth Schedule was created as an exclusive sanctuary for such legislation, shielded from judicial review. The constitutional validity of this amendment was upheld by the Supreme Court in Sankari Prasad Singh Deo v. Union of India (AIR 1951 SC 458).

The Second Amendment Act, 1952

A modest but practical amendment, the Second Amendment revised Article 81 to adjust the population-to-seat ratio for the Lok Sabha. With census figures for 1951 being higher than earlier estimates, the original formula of one seat per 7.2 lakh population had to be relaxed to one seat per 7.5 lakh — and even slightly beyond — to accommodate the actual demographic reality without breaching the overall ceiling of 500 members.

The Third Amendment Act, 1954

Entry 33 of List III (the Concurrent List) in the Seventh Schedule was amended to expand Parliament's power to legislate on the production, supply and distribution of essential commodities — foodstuffs, cattle fodder, raw cotton, cotton seed, and raw jute. This amendment was significant beyond its immediate purpose; it is this very Entry 33 that Parliament later invoked, decades later, to enact the three controversial farm laws of 2020.

The Fourth Amendment Act, 1955

The Fourth Amendment addressed the recurring friction between the State's power to acquire property and the courts' tendency to scrutinise the adequacy of compensation. Following the Supreme Court's ruling in State of West Bengal v. Bela Banerjee (AIR 1954 SC 170) that compensation must be the equivalent in money of the property acquired, Article 31 was amended to place such determinations beyond judicial review. The scope of Article 31A was also extended, and Entries 14 to 20 were added to the Ninth Schedule. Article 305 was simultaneously amended to clearly empower Parliament or a State Legislature to create a State monopoly in any sphere of trade or commerce in the public interest — a question that had been left open by the Supreme Court in Saghir Ahmed v. State of Uttar Pradesh.

The Fifth Amendment Act, 1955

This amendment was essentially procedural. It empowered the President to fix a time limit for State Legislatures to express their views on bills introduced in Parliament that affected the areas, boundaries, or names of States. Several other housekeeping changes were made — to quorum rules under Articles 100 and 189, to the service conditions of civil servants under Article 311, and to the continental shelf provision under Article 297.

The Sixth Amendment Act, 1956

A new Entry 92A was added to the Union List to enable Parliament to impose a tax on the sale or purchase of goods (other than newspapers) in the course of inter-State trade or commerce. Entry 54 of the State List was correspondingly amended, and Articles 269 and 286 were revised to restrict States' taxing power over inter-State transactions. This was the constitutional foundation for Central Sales Tax legislation. Interestingly, this architecture was ultimately displaced by the 101st Amendment introducing GST.

The Seventh Amendment Act, 1956

One of the more consequential early amendments, the Seventh Amendment gave constitutional effect to the recommendations of the States Reorganisation Commission, which had proposed reorganising States along linguistic lines. The old Part A, Part B, and Part C categorisation of States was abolished, new States were carved out, and Article 1 was amended accordingly. Provision was made for a single Governor to serve two or more States, common High Courts for two or more States, and the appointment of additional and acting judges for limited periods. Article 350A was inserted to protect the interests of linguistic minorities — a recognition that reorganisation along language lines must not leave minorities without safeguards.

The Eighth Amendment Act, 1959

Article 334 was amended to extend by ten more years the reservation of seats for Scheduled Castes and Scheduled Tribes and the special representation of Anglo-Indians in the Lok Sabha and State Legislative Assemblies. This pattern of periodic extension would repeat itself many times in the constitutional history.

The Ninth Amendment Act, 1960

Following the Supreme Court's advisory opinion in Re Berubari Union and Exchange of Enclaves (AIR 1960 SC 845), Parliament enacted the Ninth Amendment to give constitutional sanction to the transfer of the Berubari Union territory in West Bengal to Pakistan under the agreements reached between the two governments.

The Tenth Amendment Act, 1961

Dadra and Nagar Haveli, formerly a Portuguese enclave, was integrated into the Indian Union and specified as a Union Territory by amending the First Schedule and Article 240.

The Eleventh Amendment Act, 1961

Two significant changes to the electoral process for the highest constitutional offices were made. The Vice President's election was modified: instead of a joint sitting of both Houses, the Vice President was now to be elected by an electoral college consisting of members of both Houses. Article 71 was also amended to insulate elections of the President or Vice President from challenge on the ground of any vacancy in the electoral college.

The Twelfth Amendment Act, 1962

Goa, Daman and Diu were added to the First Schedule as Union Territories after their liberation from Portuguese rule. This was a formal constitutional recognition of a political and military fait accompli.

The Thirteenth Amendment Act, 1962

Following an agreement with the leaders of the Naga Peoples Convention, Article 371A was inserted, providing special protections for the State of Nagaland — notably, that no Act of Parliament would apply to Nagaland in respect of certain customary practices unless the Nagaland Legislative Assembly so decided. Nagaland was thus carved out of Assam and established as a separate State with constitutionally guaranteed autonomy over its customary law and religious practices.

The Fourteenth Amendment Act, 1963

With the French cession of their Indian territories — Pondicherry, Karikal, Mahe, and Yanam — to India, the First Schedule was amended to insert Pondicherry as Entry 9. Article 239A was inserted to enable the creation of local legislatures and Councils of Ministers for certain Union Territories, and Article 81 was amended to increase the representation of Union Territories in the Lok Sabha.

The Fifteenth Amendment Act, 1963

The retirement age of High Court judges was raised from 60 to 62 years. Article 224A was inserted to provide for the appointment of retired High Court judges as ad hoc judges. Critically, clause (1A) was inserted into Article 226, empowering High Courts to issue writs against authorities located outside their territorial jurisdiction if the cause of action arose within their territory — a provision that significantly expanded the reach of High Court writ jurisdiction.

The Sixteenth Amendment Act, 1963

On the recommendations of the Committee on National Integration and Regionalism, clauses (2), (3) and (4) of Article 19 were amended to add "sovereignty and integrity of India" as a ground for imposing reasonable restrictions. The forms of oath for members of Parliament and State Legislatures, Ministers, and judges were also revised to include a pledge to uphold the sovereignty and integrity of India — a direct response to the separatist movements of the early 1960s.

The Seventeenth Amendment Act, 1964

Article 31A was amended to ensure that no private land under personal cultivation could be acquired unless the owner received compensation at the market value of the land. Forty-four more entries were added to the Ninth Schedule to shield State land reform laws. This amendment was upheld in Sajjan Singh v. State of Rajasthan (AIR 1965 SC 845) but was subsequently struck down in the landmark Golak Nath v. State of Punjab (AIR 1967 SC 1643), which held that Parliament had no power to abridge Fundamental Rights.

The Eighteenth Amendment Act, 1966

Two explanations were added to Article 3 to make clear that Parliament's power to form new States included the power to unite a part of one State or Union Territory with another — removing an ambiguity that had generated confusion about the extent of reorganisation power.

The Nineteenth Amendment Act, 1966

The system of Election Tribunals, which had been functioning separately to hear election petitions, was abolished. The jurisdiction to hear such petitions was vested in the High Courts — a move that brought election disputes within the ordinary judicial framework.

The Twentieth Amendment Act, 1966

After the Supreme Court in Chandra Mohan v. State of UP (AIR 1966 SC 1987) declared certain appointments of District Judges in Uttar Pradesh to be illegal, Article 233A was inserted to validate those appointments retrospectively. It is a reminder that even in matters of judicial appointments, constitutional irregularities can occur and must sometimes be addressed through legislation.

The Twenty-First Amendment Act, 1967

Sindhi was added to the Eighth Schedule as the fifteenth recognised language of the Republic — a belated recognition of a language and a community that had been displaced by Partition.

The Twenty-Second Amendment Act, 1969

An autonomous State of Meghalaya was carved out within the State of Assam, with Articles 244A, 275(1A), and 371B inserted to provide for its legislative assembly and special financial provisions — a precursor to Meghalaya's eventual full statehood.

The Twenty-Third Amendment Act, 1969

The reservation of seats for Scheduled Castes and Scheduled Tribes was extended for another ten years, up to 1980. A notable addition was the amendment to Articles 330 and 332 to exclude Nagaland from such reservations, since over ninety percent of its population were already Scheduled Tribes — making the reservation device redundant.

The Twenty-Fourth Amendment Act, 1971

The Golak Nath judgment had created a constitutional crisis by holding that Parliament could not amend Fundamental Rights. To overcome this, the Twenty-Fourth Amendment amended Article 13 to clarify that it does not apply to constitutional amendments, and Article 368 was amended to expressly state that Parliament's power to amend the Constitution extends to all its provisions, including Part III. The Supreme Court upheld this amendment in the epic Kesavananda Bharati v. State of Kerala (1973) 4 SCC 225, though it simultaneously evolved the Basic Structure doctrine as a counter-limit.

The Twenty-Fifth Amendment Act, 1971

Following the Bank Nationalisation case (1970 3 SCR 530), where the Supreme Court held that the Constitution guaranteed full market-equivalent compensation for acquired property, Parliament replaced the word "compensation" with the word "amount" in Article 31(2) — making such determinations non-justiciable. Article 31C was also inserted, providing that laws giving effect to the Directive Principles in Article 39(b) and (c) would not be void for inconsistency with Articles 14, 19, or 31. This amendment, too, was upheld in Kesavananda Bharati, subject to the qualification that the portion of Article 31C that excluded judicial scrutiny was struck down.

The Twenty-Sixth Amendment Act, 1971

The privy purses and special privileges of former rulers of Indian States were abolished. Articles 291 and 362 were omitted, Article 363A was inserted, and the definition of "ruler" in Article 366 was changed — directly overruling the Supreme Court's decision in H.H. Madhav Rao Scindia v. Union of India (Privy Purses case, 1971). The amendment was later upheld in Raghunathrao Ganpatrao v. Union of India (AIR 1993 SC 1267).

The Twenty-Seventh Amendment Act, 1971

Mizoram was brought within the category of Union Territories with legislature, Arunachal Pradesh was included in Article 240, and Article 371C was inserted to provide special provisions for Manipur.

The Twenty-Eighth Amendment Act, 1972

The special conditions and privileges of Indian Civil Service officers inherited from the colonial era were abolished by inserting Article 312A and omitting Article 314 — completing the integration of the civil services into the constitutional framework applicable to all public servants.

The Twenty-Ninth Amendment Act, 1972

Two Kerala Land Reform laws were added to the Ninth Schedule, thereby shielding them from judicial challenge. These very laws subsequently became part of the material challenged in the Kesavananda Bharati case.

The Thirtieth Amendment Act, 1972

Article 133(1) was amended, on the recommendations of the Law Commission, to make the grant of a certificate for appeal to the Supreme Court dependent on whether the case involved a substantial question of law of general importance — replacing the earlier criterion based on the monetary value of the subject matter. This was a significant step in rationalising Supreme Court jurisdiction.

The Thirty-First Amendment Act, 1973

The total number of Lok Sabha seats was increased from 500 to 545. Articles 330 and 332 were also amended to ensure that the predominantly tribal States of Meghalaya, Arunachal Pradesh, and Mizoram were not burdened with reservation provisions that were unnecessary given their demographic composition.

The Thirty-Second Amendment Act, 1973

Special provisions were made for Andhra Pradesh by inserting Articles 371D and 371E — the former providing for equitable opportunities for residents of different regions in matters of education and public employment, and the latter for the establishment of a Central University in Andhra Pradesh.

The Thirty-Third Amendment Act, 1974

Articles 101(3) and 190(3) were amended to provide that a resignation of a member of Parliament or State Legislature shall not be accepted by the Speaker or Chairman unless satisfied that it is voluntary and genuine. This provision was a safeguard against forced resignations.

The Thirty-Fourth Amendment Act, 1974

Further land reform laws were added to the Ninth Schedule, inserting Entries 67 to 86 in pursuance of decisions taken at the Chief Ministers' Conference in 1972. The amendment was upheld in Glanrock Estate (P) Ltd. v. State of Tamil Nadu (2010) 10 SCC 96.

The Thirty-Fifth Amendment Act, 1974

Article 2A was inserted to associate Sikkim with the Indian Union as an "Associate State," reflecting the unique political relationship between India and Sikkim at the time, short of full integration. A Tenth Schedule was added laying down the terms and conditions of that association.

The Thirty-Sixth Amendment Act, 1975

Following a resolution of the Sikkim Assembly to abolish the institution of Chogyal and fully join the Indian Union, Sikkim was admitted as a full State. Article 371F was inserted to provide special provisions for Sikkim, and the First Schedule was amended accordingly. Article 2A and the Tenth Schedule inserted by the Thirty-Fifth Amendment were consequently omitted. The Supreme Court upheld this amendment in R.C. Poudyal v. Union of India (1994 Supp (1) SCC 324).

The Thirty-Seventh Amendment Act, 1975

Arunachal Pradesh was provided with a legislative assembly and a Council of Ministers by amending Articles 239A and 240, even while remaining a Union Territory.

The Thirty-Eighth Amendment Act, 1975

Enacted during the Emergency of 1975-77, this amendment placed the President's, Governor's, and Administrator's powers to promulgate Ordinances and declare Emergency beyond judicial scrutiny. It was a deeply controversial measure, representative of the broader assault on institutional checks that characterised the Emergency period.

The Thirty-Ninth Amendment Act, 1975

This amendment was passed to validate the election of Prime Minister Indira Gandhi, which the Allahabad High Court had set aside. Article 71 was amended to oust judicial review of Presidential and Vice Presidential elections, and the extraordinary Article 329A was inserted to place the elections of the Prime Minister and Speaker beyond the scope of all courts. The Supreme Court, in Indira Gandhi v. Raj Narain (AIR 1975 SC 2299), struck down Article 329A as violating the basic structure of the Constitution — specifically, the rule of law and the principle of free and fair elections.

The Fortieth Amendment Act, 1976

Parliament was empowered to define from time to time the limits of India's territorial waters, continental shelf, exclusive economic zone, and other maritime zones. A large block of laws — Entries 125 to 188 — was also added to the Ninth Schedule.

The Forty-First Amendment Act, 1976

The retirement age of members of State Public Service Commissions and Joint Public Service Commissions was raised from 60 to 62 years, bringing them in line with High Court judges.

The Forty-Second Amendment Act, 1976 — The "Mini Constitution"

Often called the "Mini Constitution," the Forty-Second Amendment was the most sweeping in the Constitution's history — and the most controversial. Enacted during the Emergency on the recommendations of the Swaran Singh Committee, it made radical changes across virtually every part of the Constitution.

The words "Socialist," "Secular," and "Integrity" were added to the Preamble. A new Part IVA containing Fundamental Duties under Article 51A was inserted. New Directive Principles — Articles 39A (equal justice and free legal aid), 43A (workers' participation in management), and 48A (protection of environment) — were added. The President was made categorically bound by the advice of the Council of Ministers. The tenure of the Lok Sabha and State Assemblies was raised from five to six years. Subject after subject — education, forests, wildlife, administration of justice — was shifted from the State List to the Concurrent List, tilting the federal balance sharply toward the Centre. Most remarkably, Clauses (4) and (5) were added to Article 368 to place all constitutional amendments beyond judicial scrutiny and to declare Parliament's constituent power unlimited — a provision that the Supreme Court struck down in Minerva Mills Ltd. v. Union of India (AIR 1980 SC 1789) as itself violating the basic structure.

The Forty-Third Amendment Act, 1977

After the Janata Party came to power following the end of the Emergency, Parliament moved swiftly to undo some of the worst excesses of the Forty-Second Amendment. Articles 32A, 131A, 144A, 226A, 228A, and 31D — all of which had curtailed the jurisdiction of the Supreme Court and High Courts to review the constitutionality of laws — were repealed. Judicial review was substantially restored.

The Forty-Fourth Amendment Act, 1978

The Forty-Fourth Amendment was the most comprehensive corrective to the Emergency-era excesses. The right to property was removed from the list of Fundamental Rights under Part III (Article 19(1)(f) and Article 31 were omitted) and reconstituted as a mere constitutional right under Article 300A — meaning it could be limited by ordinary legislation without having to satisfy the demanding standard of fundamental rights. The tenure of the Lok Sabha was restored to five years. The word "armed rebellion" replaced "internal disturbance" as the trigger for a National Emergency, making it harder to invoke Article 352 for essentially political crises. Crucially, it was declared that Articles 20 and 21 — the right against double jeopardy and the right to life — cannot be suspended even during a National Emergency.

The Forty-Fifth Amendment Act, 1980

Article 334 was again amended to extend the reservation of seats for Scheduled Castes and Scheduled Tribes and the representation of Anglo-Indians in Parliament and State Assemblies for another ten years, up to 1990.

The Forty-Sixth Amendment Act, 1982

A new clause (29A) was added to Article 366 to give an expanded and precise definition of "tax on the sale or purchase of goods," aimed at preventing tax avoidance. Entry 92B was simultaneously added to the Union List to cover taxes on the consignment of goods in inter-State trade — a measure to plug revenue leakages.

The Forty-Seventh Amendment Act, 1984

Entries 189 to 202 were added to the Ninth Schedule, continuing the practice of shielding land reform laws from judicial challenge.

The Forty-Eighth Amendment Act, 1984

A proviso was added to Article 356(5) to enable the extension of President's Rule in Punjab beyond the normal period — a response to the deteriorating law and order situation following Operation Blue Star.

The Forty-Ninth Amendment Act, 1984

The Sixth Schedule was extended to the tribal areas of Tripura, giving constitutional sanctity to the Tripura Tribal Areas Autonomous District Council, which had been functioning under a State Act since 1979.

The Fiftieth Amendment Act, 1984

Article 33 was amended to broaden Parliament's power to restrict fundamental rights for members of the armed forces, intelligence and counter-intelligence organisations, and personnel engaged in telecommunications set up for force purposes — recognising the unique discipline demands of national security functions.

The Fifty-First Amendment Act, 1984

Articles 330 and 332 were amended to provide for reservation of seats for Scheduled Tribes in the Lok Sabha and in the Legislative Assemblies of Nagaland and Meghalaya — States where tribal populations predominated but had lacked adequate representation.

The Fifty-Second Amendment Act, 1985 — The Anti-Defection Law

One of the most politically significant amendments, the Fifty-Second Amendment introduced the Tenth Schedule — popularly known as the Anti-Defection Law. A member of Parliament or State Legislature who voluntarily gives up party membership, or votes contrary to party directions, becomes disqualified. The law was designed to combat the debilitating practice of political defection that had destabilised governments throughout the 1970s and 1980s. The Supreme Court in Kihoto Hollohan v. Zachillhu (1992 Supp (2) SCC 651) partially struck down the law, holding that the provision ousting judicial review of the Speaker's decisions was unconstitutional for non-compliance with the ratification requirement under Article 368.

The Fifty-Third Amendment Act, 1986

Article 371G was inserted to protect the customary law, social and religious practices, and ownership and transfer of land in Mizoram from Parliamentary intervention unless the State Assembly so decides. A minimum Assembly strength of 40 was also constitutionally fixed.

The Fifty-Fourth Amendment Act, 1986

The salaries of Supreme Court and High Court judges were increased, and Parliament was empowered to revise them in future by ordinary legislation — removing the need for a constitutional amendment every time judicial salaries needed adjustment.

The Fifty-Fifth Amendment Act, 1986

Arunachal Pradesh was elevated from a Union Territory to a full State, with Article 371H inserted to give the Governor special responsibility in relation to law and order — a recognition of the State's sensitive border location.

The Fifty-Sixth Amendment Act, 1987

The Goa district of the Union Territory of Goa, Daman and Diu was constituted as the State of Goa, while Daman and Diu continued as a separate Union Territory. Article 371I was inserted for special provisions with respect to Goa.

The Fifty-Seventh Amendment Act, 1987

Reservation of seats for Scheduled Tribes in the Legislative Assemblies of Arunachal Pradesh, Meghalaya, Mizoram, and Nagaland was provided for by inserting clause (3A) to Article 332.

The Fifty-Eighth Amendment Act, 1987

Article 394A was inserted to give an authoritative Hindi text of the Constitution legal sanctity equivalent to the English text — an important step in making the Constitution accessible to the vast Hindi-speaking population.

The Fifty-Ninth Amendment Act, 1988

In view of the continuing terrorism in Punjab, the extension of President's Rule to three years was provided for, and the extraordinary Article 359A was inserted permitting the declaration of a National Emergency in Punjab on the ground of internal disturbance — provisions that stood repealed just a year later by the Sixty-Third Amendment.

The Sixtieth Amendment Act, 1988

The ceiling on the profession tax that State governments could levy was increased from Rs. 250 to Rs. 2,500 by amending Article 276(2) — a long-overdue revision that enabled States to levy profession tax on a more progressive basis.

The Sixty-First Amendment Act, 1988

The voting age was reduced from 21 to 18 years for elections to the Lok Sabha and State Legislative Assemblies by amending Article 326. This was one of the most democratically significant amendments of the decade, enfranchising millions of young citizens and reflecting the maturing of India's democratic consciousness.

The Sixty-Second Amendment Act, 1989

The reservation of seats for Scheduled Castes and Scheduled Tribes was extended for another ten years, up to 2000, by amending Article 334 — continuing what was now becoming a well-established practice of periodic renewal.

The Sixty-Third Amendment Act, 1989

The special provisions for Punjab introduced by the Fifty-Ninth Amendment — the extraordinary powers for extending President's Rule and declaring emergency on grounds of internal disturbance — were repealed. Punjab was restored to the same constitutional position as all other States.

The Sixty-Fourth Amendment Act, 1990

President's Rule in Punjab, originally proclaimed in May 1987, was extended for a further period — Article 356 was amended to permit a cumulative period of three years and six months in Punjab's case.

The Sixty-Fifth Amendment Act, 1990

Article 338 was amended to replace the single Special Officer for Scheduled Castes and Scheduled Tribes with a multi-member National Commission consisting of a Chairperson, Vice-Chairperson, and five other members — a recognition that a single officer was inadequate to discharge the comprehensive functions of safeguarding the rights of these communities.

The Sixty-Sixth Amendment Act, 1990

A large number of State land reform laws were added to the Ninth Schedule through Entries 203 to 257 — the single largest addition to that Schedule — further entrenching the protection of agrarian legislation from judicial review.

The Sixty-Seventh Amendment Act, 1990

Article 356(4) was amended to extend the President's Rule in Punjab to four years — a further extension necessitated by the unresolved militant situation in the State.

The Sixty-Eighth Amendment Act, 1991

President's Rule in Punjab was extended once more to five years from the date of its original issue — a measure that reflected the extraordinary difficulty of restoring elected government to the State.

The Sixty-Ninth Amendment Act, 1991

Articles 239AA and 239AB were inserted to give the National Capital Territory of Delhi a special constitutional status. Delhi was to have a Legislative Assembly and a Council of Ministers. The Lt. Governor was to act on the aid and advice of the Council of Ministers in most matters, but with an important qualification — matters of public order, police, and land were reserved for Parliamentary legislation. This amendment gave birth to a structural tension between the elected government and the Lt. Governor that has been the subject of landmark Supreme Court decisions, most recently in State of NCT of Delhi v. Union of India (2018 8 SCC 501).

The Seventieth Amendment Act, 1992

The definition of "electoral college" for the election of the President was clarified to include members of the Legislative Assemblies of Union Territories of Delhi and Pondicherry — recognising the democratic character of these newly empowered territories.

The Seventy-First Amendment Act, 1992

Konkani, Manipuri, and Nepali were added to the Eighth Schedule, bringing the total number of recognised languages to eighteen. This acknowledged the rich linguistic diversity of India's northeastern region and the coastal heritage of Goa.

The Seventy-Second Amendment Act, 1992

Persons displaced from Chakma territory in what is now Bangladesh, who had settled in Tripura, were provided temporary protection from the operation of the Sixth Schedule — a measure addressing the humanitarian consequences of the Partition's long aftermath.

The Seventy-Third Amendment Act, 1992 — Panchayati Raj

Part IX was inserted into the Constitution, comprising Articles 243 to 243O, establishing a constitutional framework for Panchayati Raj institutions — the three-tier system of rural self-government at village, intermediate, and district levels. The amendment mandated reservation of seats for Scheduled Castes, Scheduled Tribes, and women, and required regular elections through State Election Commissions. It was a landmark in the history of Indian democracy, fulfilling the Directive Principle in Article 40 that had remained unimplemented for four decades.

The Seventy-Fourth Amendment Act, 1992 — Urban Local Bodies

Part IXA was inserted, comprising Articles 243P to 243ZG, to give constitutional status to urban local bodies — Municipalities and Municipal Corporations. Like the Seventy-Third Amendment for rural areas, this amendment mandated elections, reservation for women and marginalised communities, and the devolution of functions to these bodies. Together, the Seventy-Third and Seventy-Fourth Amendments completed the architecture of the constitutional vision for democratic decentralisation.

The Seventy-Fifth Amendment Act, 1994

Article 323B was amended to authorise State legislatures to establish Rent Tribunals for adjudicating landlord-tenant disputes — aimed at expediting the resolution of rent control litigation that had long clogged the dockets of regular courts.

The Seventy-Sixth Amendment Act, 1994

The Tamil Nadu Backward Classes, Scheduled Castes and Scheduled Tribes Reservation Act, 1993 — which provided for reservations exceeding the fifty percent ceiling laid down by the Supreme Court in Indra Sawhney v. Union of India — was added to the Ninth Schedule. This was a direct response to the political crisis that had followed the Indra Sawhney judgment.

The Seventy-Seventh Amendment Act, 1995

Article 16(4A) was inserted, empowering the State to make provisions for reservation in promotions in favour of Scheduled Castes and Scheduled Tribes which were not adequately represented in services — a legislative reversal of the Supreme Court's ruling in Indra Sawhney that reservations could not extend to promotions.

The Seventy-Eighth Amendment Act, 1995

A fresh batch of land reform laws was added to the Ninth Schedule as Entries 258 to 282, extending the protections of the Schedule to State legislation that had come into force after earlier amendments.

The Seventy-Ninth Amendment Act, 1999

Article 334 was again amended to extend the reservation of seats for Scheduled Castes and Scheduled Tribes in Parliament and State Assemblies by another ten years, up to 2010.

The Eightieth Amendment Act, 2000

Following the recommendations of the Tenth Finance Commission, Article 269 was amended to provide an alternative scheme for the devolution of taxes — essentially restructuring the sharing of Central tax revenues with States in a more consolidated fashion.

The Eighty-First Amendment Act, 2000

Article 16(4B) was inserted to provide that unfilled backlog vacancies in reserved posts would not be considered part of the fifty percent ceiling for reservations in any given year — effectively permitting the State to carry forward unfilled reservations without being subject to the ceiling. This was another legislative response to judicial decisions that had restricted reservation policy.

The Eighty-Second Amendment Act, 2000

A proviso was added to Article 335 to permit the State to relax qualifying marks or standards of evaluation for Scheduled Castes and Scheduled Tribes in matters of promotion to any class or classes of services.

The Eighty-Third Amendment Act, 2000

Article 243M was amended to clarify that the reservation provisions of the Panchayati Raj chapter would not apply to Arunachal Pradesh, which has an overwhelmingly tribal population requiring no such protection.

The Eighty-Fourth Amendment Act, 2001

Article 55 was amended along with the provisions relating to delimitation to extend the freeze on Lok Sabha and State Assembly seats — which had been fixed on the basis of the 1971 census — for another twenty-five years, up to 2026, based on figures from the 1991 census. This was to prevent States that had more successfully implemented population control measures from being penalised by losing seats.

The Eighty-Fifth Amendment Act, 2001

Article 16(4A) was further amended to provide for consequential seniority in promotions given to Scheduled Castes and Scheduled Tribes in reservation — addressing the concern that promotion under reservation, without corresponding seniority, was meaningless.

The Eighty-Sixth Amendment Act, 2002

This amendment has a special significance. Article 21A was inserted, making the right to free and compulsory education for children between the ages of 6 and 14 a Fundamental Right — the first new Fundamental Right to be added since the Constitution came into force. Article 45 was amended to shift the focus of the Directive Principle on children's education to the pre-school age group, and Article 51A was amended to add a Fundamental Duty on parents to provide opportunities for education to their children.

The Eighty-Seventh Amendment Act, 2003

The provision for delimitation of Lok Sabha and Assembly constituencies was amended to use the 2001 census figures as the basis for delimitation — a consequential adjustment that reflected the demographic reality of the new century.

The Eighty-Eighth Amendment Act, 2003

Article 268A was inserted to provide for taxes on services to be levied by the Union, collected by both the Union and the States, and apportioned between them — the constitutional foundation for the service tax, which would subsequently grow into one of the Union's most important revenue sources.

The Eighty-Ninth Amendment Act, 2003

The National Commission for Scheduled Castes and the National Commission for Scheduled Tribes were separated by amending Article 338 and inserting Article 338A — recognising that the distinct challenges faced by these two communities warranted dedicated institutional attention.

The Ninetieth Amendment Act, 2003

Article 332 was amended to preserve the reservation of seats for Scheduled Tribes and non-tribal communities in the Bodoland Territorial Areas District and the Legislative Assembly of Assam — addressing the concerns arising from the creation of the Bodoland Territorial Council.

The Ninety-First Amendment Act, 2003

The Council of Ministers at the Union and State level was capped at fifteen percent of the total membership of the Lok Sabha or State Legislative Assembly — a measure to check the phenomenon of oversized cabinets that had become a drain on the exchequer. Article 75(1A) and Article 164(1A) were inserted for this purpose.

The Ninety-Second Amendment Act, 2003

Bodo, Dogri, Maithili, and Santhali were added to the Eighth Schedule, bringing the total number of recognised languages to twenty-two — a number that has remained unchanged to the present day.

The Ninety-Third Amendment Act, 2006

Article 15(5) was inserted, empowering the State to make special provisions for the advancement of socially and educationally backward classes, or for Scheduled Castes and Scheduled Tribes, in relation to their admission to educational institutions — including private unaided institutions — other than minority institutions. This paved the constitutional way for the Central Educational Institutions (Reservation in Admission) Act and was upheld by the Supreme Court in Ashoka Kumar Thakur v. Union of India (2008 6 SCC 1).

The Ninety-Fourth Amendment Act, 2006

Article 164 was amended to remove the constitutional requirement for a Minister in charge of tribal welfare in the States of Chhattisgarh, Jharkhand, Madhya Pradesh, and Odisha — a removal balanced by the requirement of such a minister in Jharkhand, which had been carved out of Bihar with a large tribal population.

The Ninety-Fifth Amendment Act, 2009

Article 334 was amended to extend the reservation of seats for Scheduled Castes and Scheduled Tribes and the representation of Anglo-Indians in Parliament and State Assemblies for another ten years, up to 2020.

The Ninety-Sixth Amendment Act, 2011

The Eighth Schedule was amended to substitute "Odia" for "Oriya" as the correct name of the language spoken in Odisha — a correction reflecting the authentic pronunciation and the aspirations of the Odia-speaking people.

The Ninety-Seventh Amendment Act, 2011

Part IXB was inserted into the Constitution, Articles 243ZH to 243ZT, to bring cooperative societies within the constitutional framework of democratic governance — mandating elections, limiting the size of boards, and providing for audit and supersession. This amendment was partly struck down by the Supreme Court in Union of India v. Rajendra N. Shah (2021) for non-compliance with the ratification requirement under Article 368, insofar as it affected matters in the exclusive State domain.

The Ninety-Eighth Amendment Act, 2012

Article 371J was inserted to make special provisions with respect to the State of Karnataka — specifically for the Hyderabad-Karnataka region, providing for reservation in educational and employment opportunities for persons belonging to that region, addressing the longstanding developmental imbalance within the State.

The Ninety-Ninth Amendment Act, 2014

This amendment, which inserted Articles 124A, 124B, and 124C and amended Article 127 to establish the National Judicial Appointments Commission (NJAC), was one of the most controversial in recent memory. It was struck down in its entirety by the Supreme Court in Supreme Court Advocates-on-Record Association v. Union of India (2016 5 SCC 1), as violating the basic structure of the Constitution — specifically, judicial independence and the separation of powers. The collegium system of judicial appointments was thus restored.

The Hundredth Amendment Act, 2015

Under the Land Boundary Agreement of 1974 as amended in 2011, India exchanged certain enclaves with Bangladesh. The Constitution was amended by modifying the First Schedule to give effect to this territorial exchange — completing a process of rationalising the border that had been pending for decades.

The Hundred and First Amendment Act, 2016 — GST

The most transformative economic reform in India's post-liberalisation history was given constitutional shape by the Hundred and First Amendment. A new Article 246A was inserted, conferring concurrent power on Parliament and State Legislatures to make laws with respect to goods and services tax — a single, unified indirect tax replacing a multiplicity of Union and State levies. The GST Council was constituted under Article 279A, bringing the Centre and States together in a shared governance framework for indirect taxation. This amendment fundamentally restructured the fiscal federalism of the Constitution and has been cited as an example of radical constitutional innovation that survives basic structure scrutiny.

The Hundred and Second Amendment Act, 2018

Article 338B was inserted to establish the National Commission for Backward Classes as a constitutional body, and Article 342A was inserted to empower the President to specify Socially and Educationally Backward Classes (SEBCs). This gave the Commission constitutional status equivalent to the National Commissions for Scheduled Castes and Scheduled Tribes.

The Hundred and Third Amendment Act, 2019

Articles 15(6) and 16(6) were inserted to provide for reservations up to ten percent in educational institutions and government employment for Economically Weaker Sections (EWS) of citizens — those not covered by the existing reservation framework. This was the first time economic criterion alone was used to identify a class for reservation, breaking from the tradition rooted in social backwardness. The amendment was upheld by a five-judge bench of the Supreme Court in Janhit Abhiyan v. Union of India (2022 SCC OnLine SC 1540) by a majority of three to two, though the minority raised significant concerns about the exclusion of OBCs, SCs, and STs from the ten percent EWS quota.

The Hundred and Fourth Amendment Act, 2019

The reservation of seats for Scheduled Castes and Scheduled Tribes in the Lok Sabha and State Legislative Assemblies was extended by another ten years, now up to 26 January 2030 — but with a significant departure: the Anglo-Indian community's special representation, which had been periodically renewed since 1950, was discontinued. Article 334 was amended accordingly.

The Hundred and Fifth Amendment Act, 2021

In Jaishri Laxmanrao Patil v. State of Maharashtra (2021 8 SCC 1), the Supreme Court had held that the power to specify Socially and Educationally Backward Classes under Article 342A vested exclusively in the President. The Hundred and Fifth Amendment reversed this by clarifying that States retain the power to identify and notify SEBCs for matters within their own List and under their control — with the President's power confined to Union matters. This amendment has been seen as a federalism-affirming correction that restores meaningful State autonomy in the domain of reservation policy.

The Hundred and Sixth Amendment Act, 2023 — Women's Reservation

The most recent constitutional amendment — and in terms of its potential, one of the most consequential — reserves one-third of the seats in the Lok Sabha, State Legislative Assemblies, and the Delhi Assembly for women by inserting Articles 330A and 332A and Article 334A. However, in an unusual constitutional arrangement, the actual operation of these provisions is contingent upon the completion of a delimitation exercise based on the figures of the first census taken after the commencement of this amendment. The amendment is thus, for the time being, in a state of suspended animation — awaiting a census and a delimitation before it breathes political life. The question of when the Government will exercise its discretion to bring the amendment into force has already generated considerable debate about the Government's obligation and the relationship between constitutional mandate and political will.
