105th Constitutional Amendment Act, 2021: A Complete Guide to Provisions, Power & Recent Case Laws
Introduction: Why This Amendment Shook Indian Federalism
Imagine waking up one morning to find that your state government no longer has the power to decide who is "backward" in your own state. That is exactly what happened in India in May 2021. The Supreme Court, in a landmark judgment, read the 102nd Constitutional Amendment to mean that only the Central Government could identify socially and educationally backward classes. This single decision put the reservation lists of nearly every Indian state into legal doubt.
Within just three months, Parliament acted with rare speed and unity. It passed the 105th Constitutional Amendment Act, 2021 — formally known as the Constitution (One Hundred and Fifth Amendment) Act, 2021 — to restore the power of states to make their own lists of backward classes. This amendment is short, technical, and easy to overlook in a textbook. But it sits at the heart of one of the biggest questions in Indian public life: Who gets to decide who is backward — the Centre or the states?
This article walks you through everything you need to know about the 105th Amendment. We will cover the exact provisions, the story behind it, the recent case laws that have shaped its meaning, and why it matters for the future of reservation and federalism in India.
The Story Behind the Amendment: From the 102nd to the Maratha Judgment
The 102nd Amendment (2018): Good Intentions, Bad Wording
To understand the 105th Amendment, you must first understand the 102nd Constitutional Amendment Act, 2018. This amendment did something the backward-class movement had wanted for years — it gave the National Commission for Backward Classes (NCBC) full constitutional status. Before 2018, the NCBC was only a statutory body created by a 1993 law. It was weaker than the National Commissions for Scheduled Castes and Scheduled Tribes, which already had their own constitutional articles.
The 102nd Amendment fixed this by inserting three new pieces into the Constitution:
- Article 338B — Created the NCBC as a constitutional commission, giving it the same footing as the SC and ST commissions. It could investigate complaints and advise the government on the welfare of backward classes.
- Article 342A — Gave the President of India the power, in consultation with the Governor, to notify the list of "socially and educationally backward classes" (SEBCs) for each state. Once that list was published, only Parliament could add or remove a community from it.
- Article 366(26C) — Added a definition clause that defined SEBCs as the classes deemed backward under Article 342A.
The intention was clear: give backward classes a strong constitutional guardian and a clear identification process. But the wording of Article 342A was ambiguous on one crucial point. It spoke of "the" list of SEBCs notified by the President. It did not clearly say whether states could still keep their own separate lists for their own reservations, the way they always had. That silence is where the trouble started.
The Maratha Reservation Case: The Judgment That Changed Everything
The ambiguity came to a head in the Maratha reservation case. In November 2018, the Maharashtra state legislature passed a law giving the Maratha community a separate reservation in jobs and education, over and above the existing quotas. When that law was challenged, the Supreme Court heard it as Dr. Jaishri Laxmanrao Patil v. Chief Minister, Maharashtra, and a five-judge Constitution Bench led by Justice Ashok Bhushan delivered its verdict on 5 May 2021.
The bench struck the Maratha quota down unanimously on one ground: it pushed Maharashtra's total reservation well past the 50% ceiling that the court had fixed back in the Indra Sawhney case of 1992, and the Marathas were not an "exceptional case" that justified crossing it.
But the judgment carried a second, far more disruptive holding. By a 3:2 majority, the court read the 102nd Amendment as having taken the power to identify SEBCs away from the states altogether. After 2018, the majority said, only the President — that is, the Union government — could notify who counted as backward in a state. States could merely recommend names to the Centre.
Think about what that meant in practice. Every state had its own backward-class list, built over decades to fit local caste realities — the Vokkaligas and Lingayats in Karnataka, the Jats and Gujjars elsewhere, hundreds of communities in each state. If only the Centre could now notify those lists, every one of them was suddenly on shaky legal ground. States had effectively lost a power they had exercised since the Constitution began.
The Union government, across party lines, decided this could not stand. It promised a constitutional amendment to put the matter beyond doubt.
What the 105th Amendment Actually Does: Exact Provisions
The amendment was introduced as the 127th Constitutional Amendment Bill, 2021 and moved with extraordinary speed. It was brought into the Lok Sabha on 9 August 2021, passed the lower house on 10 August 2021 with 380 votes in favour and not a single vote against it, and cleared the Rajya Sabha the next day, 11 August 2021, by 187 votes to none. The President gave assent on 18 August 2021, and the Act is deemed to have come into force from 15 August 2021 — Independence Day. Because it touches the federal balance of power, it also needed ratification by the legislatures of at least half the states under the special procedure in Article 368, which it received.
On the substance, the amendment does one thing and does it cleanly: it puts back, in black and white, the states' power to maintain their own backward-class lists.
The Exact Changes Made by the 105th Amendment
The 105th Amendment made precise, surgical changes to three articles of the Constitution. Here is exactly what it did:
- Article 342A(1) and (2) were rewritten — The list that the President notifies is now explicitly called the "Central List" — meant for the purposes of the Union government alone. An explanation was inserted after clause (2) to make this crystal clear: the "Central List" means the list of SEBCs prepared and maintained by and for the Central Government.
- Article 342A(3) was added as a brand-new clause — This is the heart of the amendment. It says: "Notwithstanding anything contained in clauses (1) and (2), every State or Union territory may, by law, prepare and maintain, for its own purposes, a list of socially and educationally backward classes, entries in which may be different from the Central List." This is a non-obstante clause — it overrides clauses (1) and (2) and gives states their power back.
- Article 366(26C) was amended — The definition of "socially and educationally backward classes" was expanded to cover both the centrally notified classes and those on a state list, depending on whose purpose is in question. It now reads: "socially and educationally backward classes" means such backward classes as are deemed under article 342A for the purposes of the Central Government or the State or Union territory, as the case may be.
- Article 338B was adjusted — A proviso was added to clause (9) of Article 338B so that the NCBC's power to be consulted on policy matters does not apply to the separate state lists under Article 342A(3). States do not have to route their own lists through the NCBC.
The Result: Two Parallel Lists
After the 105th Amendment, the constitutional framework works like this:
- Central List (Article 342A(1)) — Notified by the President, used for central government jobs and central institutions, changed only by Parliament, and the NCBC is consulted on it.
- State / UT List (Article 342A(3)) — Notified by each state and Union Territory, used for that state's own reservations, recruitment and admissions, and the list may be different from the Central List. States need not route their lists through the NCBC.
This restores the pre-2021 position: two parallel tracks, one for the Centre and one for each state.
Why This Amendment Matters: Federalism, Social Justice & OBC Politics
Protecting Cooperative Federalism
The deepest significance of the 105th Amendment is federal. Identifying who is backward had always been a shared exercise — the Centre kept a list for its own posts, but states, which run the bulk of public employment and education, kept theirs. The 2021 reading of the 102nd Amendment threatened to centralise all of that in one stroke.
By restoring the state lists, the 105th Amendment reaffirmed a basic logic of Indian federalism: a state legislature in Bengaluru or Patna usually understands its own caste landscape better than a notification issued from Delhi. Social justice works best when that local knowledge is respected.
Protecting Millions of OBC Beneficiaries
The amendment protected a vast number of existing reservations at one go. The Central List alone covers more than 2,600 OBC communities, and states carry their own lists on top of that — a system serving hundreds of millions of people. Had the May 2021 reading been left standing, much of that scaffolding would have needed re-notification through the Centre, with all the litigation and uncertainty that implies.
It is estimated that about 671 OBC communities would have lost access to reservations in educational institutions and government appointments if the state lists had been abolished. The 105th Amendment closed that gap and steadied the ground for state-level OBC quotas across the country.
Political Unity Across Party Lines
Politically, the amendment landed in territory that no party wanted to be on the wrong side of, which is why the votes were near-unanimous in both houses. Backward-class assertion is one of the strongest currents in Indian electoral life, and the idea that states had "lost" the power to recognise their own OBCs was politically untenable. The amendment let every party claim credit for restoring it.
It also quietly kept alive the space for states to experiment with sub-categorising their OBC lists — sorting backward communities into bands so that benefits reach the genuinely under-served. This debate was taken up at the central level by the Justice G. Rohini Commission, which submitted its report on OBC sub-categorisation to the President in July 2023.
What the 105th Amendment Did NOT Do: Important Limits
It is just as important to be clear about what the 105th Amendment did not do, because many people confuse its purpose.
- It did not increase reservation quotas. It restored a power; it did not expand a quota.
- It did not revive the Maratha quota. The amendment deliberately left untouched the 50% ceiling on total reservations laid down in Indra Sawhney v. Union of India (1992). Restoring the states' power to identify SEBCs did nothing to let them breach that 50% cap.
- It did not change the creamy-layer rule. The principle that the better-off section within a backward class should be kept out of reservation remains untouched.
- It did not make the 105th Amendment retrospective. The amendment is deemed to have come into force from 15 August 2021, and it does not automatically validate state laws passed between the 102nd Amendment (August 2018) and the 105th Amendment (August 2021).
That ceiling remains the live wire in Indian reservation politics. States from Tamil Nadu to Bihar have pushed total reservations past 50%, and the question of whether and when the cap can be crossed keeps returning to the courts.
Recent Case Laws and Judicial Interpretation
The 105th Amendment has been tested and interpreted in several important cases since its enactment. Here are the key ones:
1. Dr. Jaishri Laxmanrao Patil v. Chief Minister, Maharashtra (2021) — The Trigger Case
This is the case that started it all. In May 2021, a five-judge Constitution Bench struck down the Maharashtra SEBC Act, 2018, which granted 16% reservation to the Maratha community.
- The bench held unanimously that the reservation breached the 50% ceiling fixed in Indra Sawhney (1992).
- By a 3:2 majority, it held that the 102nd Amendment had centralised the power to identify SEBCs in the President alone, taking it away from states.
- The majority, led by Justice Ravindra Bhat, preferred a "literal interpretation" of the constitutional text, holding that the court cannot read in state powers that the text does not explicitly contain.
- The minority, led by Justice Ashok Bhushan, preferred a "purposive interpretation", arguing that the 102nd Amendment was never intended to strip states of their powers.
This judgment forced Parliament's hand and led directly to the 105th Amendment.
2. Pattali Makkal Katchi v. A. Mayilerumperumal (2022) — The Retrospectivity Question
This case, decided by the Supreme Court on 31 March 2022, is the most important post-105th Amendment judgment. It concerned the Tamil Nadu Special Reservation Act, 2021, which provided 10.5% internal reservation for the Vanniyar community within the 20% quota for Most Backward Classes (MBCs).
The Tamil Nadu Act was passed on 26 February 2021 — after the 102nd Amendment (August 2018) but before the 105th Amendment (August 2021). The Madras High Court had quashed it, holding that the state lacked legislative competence at the time of enactment.
The Supreme Court, in a judgment by Justices L. Nageswara Rao and B.R. Gavai, upheld the Madras High Court's decision and declared the Tamil Nadu Act unconstitutional. The Court held:
- The State government was legislatively competent to provide internal reservations, but it had erred by using antiquated and unreliable data to frame the 2021 Act.
- The Act discriminated against other MBC groups who could not claim this large share of reserved seats.
- Most importantly, the Court held that the 105th Amendment does not have retrospective effect. The Tamil Nadu Act was enacted at a time when the 102nd Amendment had restricted the states' power to identify SEBCs. The State could not rely on the 105th Amendment, which had not yet been enacted, to retrospectively validate its legislative action.
The Court also clarified that sub-classification within a reservation category is constitutionally permissible, but it must be based on adequate quantifiable data demonstrating differential backwardness. Caste identity alone is not a sufficient basis for such sub-classification.
This case is a landmark because it established that:
- The 105th Amendment is not retrospective.
- States must have empirical data to justify sub-classification.
- The period between the 102nd and 105th Amendments (August 2018 to August 2021) was a "legal vacuum" where states lacked the power to identify new SEBCs.
3. Madras High Court Judgment on Vanniyar Reservation (2021)
Before the Supreme Court decided Pattali Makkal Katchi, the Madras High Court had already quashed the Tamil Nadu Vanniyar reservation law in 2021. The High Court held:
- By virtue of the 102nd Constitutional Amendment, the powers of the Legislative Assembly to include and exclude backward classes had been ousted and bestowed with Parliament under Article 342A.
- The 105th Amendment, enacted on 19 August 2021, could not save a law enacted on 26 February 2021, because as on the date of enactment of the impugned Act, the State Legislature had no power to enact such legislation.
This High Court judgment was the basis for the Supreme Court's later affirmation in Pattali Makkal Katchi.
4. Kerala High Court Stay on Christian Nadar Inclusion (2021)
Following the same logic as the Madras High Court, the Kerala High Court stayed the operation of a Government Order dated 6 February 2021 that sought to include the Christian Nadar community under the SEBC communities in the State. The Court cited the Maratha judgment and the fact that the state lacked power during the period between the 102nd and 105th Amendments.
This case reinforced the principle that any state action to identify or include communities as SEBCs between August 2018 and August 2021 was legally invalid.
5. State of Punjab v. Davinder Singh (2024) — The Sub-Classification Debate
While not directly about the 105th Amendment, this case is crucial for understanding the broader reservation landscape. In August 2024, a seven-judge bench of the Supreme Court held by a 6:1 majority that states may sub-classify Scheduled Castes and Scheduled Tribes to direct benefits toward the most disadvantaged.
The Court also signalled that a creamy-layer logic could reach even SC/ST quotas. This decision sits alongside the 105th Amendment in the larger, unfinished argument about reservation: the 105th Amendment answered the narrow question of who identifies backward classes, while cases like Davinder Singh continue to shape the harder questions of how much reservation, for whom, and how finely sliced.
The Broader Significance: A Federal Correction, Not a Reservation Settlement
The 105th Constitutional Amendment is best understood as a precise federal correction — it restored who decides, but it did not settle the larger reservation debate. Here is what that means in simple terms:
- Who decides who is backward? — Both the Centre and the states, through parallel lists.
- How much reservation can be given? — The 50% ceiling from Indra Sawhney (1992) remains untouched.
- Can states sub-classify within OBCs? — Yes, but only with empirical data (as held in Pattali Makkal Katchi).
- Can the creamy layer be excluded? — Yes, that principle continues.
- Is the amendment retrospective? — No, as firmly established by the Supreme Court in 2022.
The amendment is a testament to how the Indian constitutional system works: the judiciary interprets the Constitution, and when Parliament disagrees with that interpretation, it can amend the Constitution to clarify its intent. In this case, Parliament moved with remarkable speed and unity to correct what it saw as a judicial overreach into the federal structure.
Conclusion: Why the 105th Amendment Still Matters Today
The 105th Constitutional Amendment Act, 2021, is more than a technical fix. It is a statement about cooperative federalism and social justice in India. It tells us that:
- The Centre and states must work together on reservation, but each has its own sphere.
- Local knowledge matters — a state knows its own caste realities better than a distant central authority.
- Constitutional amendments can be swift and unanimous when the political will exists.
- The judiciary's interpretation of the Constitution is not final if Parliament, in its constituent capacity, chooses to clarify the text.
For students, lawyers, and citizens, the 105th Amendment is a living example of how the Constitution adapts to real-world challenges. It shows that the document is not static — it breathes, it changes, and it responds to the needs of the people.
As India continues to grapple with questions of caste, reservation, and equality, the 105th Amendment stands as a crucial milestone. It did not solve every problem, but it solved the immediate crisis of federal power over backward-class identification. And in a democracy as diverse as India's, that is no small achievement.
