Article 262 and the Inter-State River Water Disputes Act, 1956
Updated 8 Oct 2026: Added that a published award is final and binding under Section 6(1), and the June 2018 Cauvery Water Management Scheme under Section 6A.
When a river flows through two or more states, those states often fight over how much water each one should get. Article 262 of the Indian Constitution gives Parliament the power to make a special law to settle such fights. Using this power, Parliament passed the Inter-State River Water Disputes Act, 1956 (ISRWD Act). Under this law, the Centre sets up a special body called a water disputes tribunal, made up of judges, which hears both sides and decides how the water should be shared.
Why is a special system needed?
A river does not stop at a state border. If an upstream state (the state where the river flows first) builds big dams, less water reaches the downstream state. Farmers, cities and industries downstream then suffer. These fights involve huge technical questions: how much water flows in a normal year, in a dry year, how much each crop needs. Ordinary courts are not designed to handle this. So the Constitution makers created a separate path: a dedicated tribunal with expert help, whose decision is final.
Who controls water under the Constitution?
Water is mainly a state subject, but with an important limit:
- Entry 17 of the State List (Seventh Schedule) gives states power over water supply, irrigation, canals, drainage, embankments, water storage and water power.
- But Entry 17 is "subject to" Entry 56 of the Union List. Entry 56 lets the Union regulate and develop inter-state rivers and river valleys, to the extent Parliament declares this to be useful in the public interest.
You can think of it like a shared family house. Each family member controls their own room (the state's own water), but the common staircase (the inter-state river) needs rules that the head of the house (Parliament) can make.
What does Article 262 say?
It has two clauses:
- Article 262(1): Parliament may, by law, provide for the adjudication (formal deciding) of any dispute or complaint about the use, distribution or control of the waters of any inter-state river or river valley.
- Article 262(2): Parliament may, by law, provide that neither the Supreme Court nor any other court will exercise jurisdiction (the power to hear a case) over such a dispute.
Article 262 sits in Part XI of the Constitution, which deals with relations between the Union and the states. Note that Article 262 does not itself create any tribunal. It only allows Parliament to make a law, and Parliament did so in 1956.
Where did it come from?
The Government of India Act, 1935 had a similar idea in its Sections 130 to 134: water disputes between provinces went to the Governor-General, who could appoint a commission. The Constitution makers kept the idea of a special forum but gave the power to Parliament. In 1956, Parliament passed two laws together under Entry 56 and Article 262:
- the Inter-State River Water Disputes Act, 1956, to settle disputes through tribunals; and
- the River Boards Act, 1956, to set up river boards that would advise on joint development of a river. (No river board has ever actually been set up under this second Act.)
Later, the Sarkaria Commission on Centre-state relations (report in 1988) found that tribunals took far too long, and recommended time limits. Based on this, Parliament passed the Inter-State River Water Disputes (Amendment) Act, 2002.
How does the process work, step by step?
- Complaint: A state government sends a complaint to the Centre under Section 3 of the Act, saying another state's action (for example, a new dam) is hurting it.
- Negotiation first: The Centre tries to settle the matter through talks between the states.
- Tribunal: If talks fail, the Centre must set up a tribunal under Section 4. Since the 2002 amendment, this must be done within one year of the request. The tribunal has a chairperson and two other members, all sitting or retired judges of the Supreme Court or High Courts, nominated by the Chief Justice of India. Expert assessors can help it.
- Award: The tribunal studies the case, visits sites, and gives its decision, called an award. Since 2002, it should do so within three years, which can be extended by up to two more years.
- Clarification: Under Section 5(3), the Centre or any state can ask the tribunal to explain or clarify its award within three months. The tribunal then gives a further report.
- Publication: The award becomes binding only when the Centre publishes it in the Official Gazette (the government's official notice book). Under Section 6(1), the published award is final and binding on the states in the dispute, and they must carry it out. The Act has no separate procedure for reopening a published award because circumstances have changed later. Under Section 6(2), added in 2002, a published award has the same force as an order or decree of the Supreme Court.
- Implementation: Under Section 6A, the Centre can frame a scheme, for example a management authority, to make sure the award is actually followed. The Cauvery Water Management Scheme, 2018 was made under this section.
Section 11: the court bar
Section 11 of the Act uses the power in Article 262(2). It says that neither the Supreme Court nor any other court shall have jurisdiction over a water dispute that can be referred to a tribunal under this Act. This is why a state cannot simply file a fresh suit in the Supreme Court to get more water from a river.
But the Supreme Court is not fully shut out
The Court has said it can still hear appeals against a tribunal's final award under Article 136 (special leave to appeal). In the Cauvery case (State of Karnataka v. State of Tamil Nadu), the Court first held in December 2016 that such appeals can be heard, and then, on 16 February 2018, it changed the Cauvery tribunal's award.
It cut Tamil Nadu's share from Karnataka from 192 TMC to 177.25 TMC a year (TMC = thousand million cubic feet, a unit of water volume). It also ordered a scheme to implement it, which led to the Cauvery Water Management Authority in 2018. The Centre notified this scheme, the Cauvery Water Management Scheme, 2018, under Section 6A on 1 June 2018.
It set up two bodies: the Cauvery Water Management Authority (CWMA), which oversees storage, sharing and control of Cauvery water, and the Cauvery Water Regulation Committee (CWRC), which gives it technical support.
India's water tribunals so far
These are the ones UPSC asks about most:
| Tribunal | Set up | States involved | Status |
|---|---|---|---|
| Krishna (first, Bachawat) | 1969 | Maharashtra, Karnataka, Andhra Pradesh | Award 1973, published 1976 |
| Godavari | 1969 | Maharashtra, Karnataka, Andhra Pradesh, Madhya Pradesh, Odisha | Award 1980 |
| Narmada | 1969 | Gujarat, Madhya Pradesh, Maharashtra, Rajasthan | Award 1979 |
| Ravi and Beas | 1986 | Punjab, Haryana, Rajasthan | Still pending |
| Cauvery | 1990 | Karnataka, Tamil Nadu, Kerala, Puducherry | Final award 2007, modified by Supreme Court 2018 |
| Krishna (second, Brijesh Kumar) | 2004 | Maharashtra, Karnataka, Andhra Pradesh (later Telangana too) | Award given; matter still in courts |
| Vansadhara | 2010 | Odisha, Andhra Pradesh | Final report September 2017 |
| Mahadayi (Mandovi) | 2010 | Goa, Karnataka, Maharashtra | Award August 2018 |
| Mahanadi | 2018 | Odisha, Chhattisgarh | Still hearing the case |
The 2019 reform that did not happen
The government brought the Inter-State River Water Disputes (Amendment) Bill, 2019. Lok Sabha passed it on 31 July 2019. It proposed:
- a Disputes Resolution Committee (DRC) to first try friendly talks for one year (extendable by six months);
- one single, permanent tribunal with several benches, replacing all the separate tribunals;
- a fixed time limit for awards, and a data agency to collect river data.
The Bill was pending in Rajya Sabha for years. It lapsed in 2024 when the 17th Lok Sabha was dissolved, under Article 107(5) of the Constitution, which says a Bill passed by Lok Sabha and pending in Rajya Sabha lapses when Lok Sabha is dissolved.
Commonly confused concepts
- Article 262 vs Article 131: Article 131 gives the Supreme Court "original jurisdiction" over disputes between the Centre and states, or between states. But for water disputes, Article 262 and Section 11 of the ISRWD Act keep such disputes out of Article 131. So a state cannot go straight to the Supreme Court under Article 131 for water sharing.
- Original suit vs appeal: The court bar stops a fresh case on water sharing. It does not stop an appeal against a final award under Article 136, as the Cauvery case shows.
- ISRWD Act vs River Boards Act: Both were passed in 1956. The ISRWD Act is for settling fights. The River Boards Act is for joint planning and advice. Only the first has really been used.
- Tribunal award vs management authority: The tribunal decides who gets how much water. A body like the Cauvery Water Management Authority makes sure that decision is followed, season by season.
- Inter-state dispute vs international river treaty: Disputes between Indian states go to tribunals under this Act. Sharing with another country, such as the Ganga with Bangladesh, is done through treaties signed by the Union government.
Issues, criticism and the way forward
- Very long delays: Many tribunals take decades. The Ravi and Beas tribunal has been working since 1986. The Cauvery tribunal took 17 years for its final award.
- Awards not followed: States sometimes refuse to accept an award and protest. Without a strong implementation body, an award can stay only on paper.
- No reliable shared data: States often present different figures for how much water the river carries. There is no single, accepted national data bank for each basin, so each tribunal starts its work by fighting over numbers.
- Political pressure: Water is an emotional issue for farmers, so state governments often take hard positions before elections.
- Too much legal, too little scientific: Critics say a river basin should be managed as one living system, with all states planning together, rather than divided like property.
- Way forward: Experts and the Sarkaria Commission suggest faster timelines, a permanent tribunal, a national data agency, basin-level authorities, and a stronger push for negotiated settlements before litigation. Many of these ideas were in the 2019 Bill.
Concepts to Know
- Adjudication: Deciding a dispute in a formal way, like a judge does, after hearing both sides.
- Jurisdiction: The legal power of a court or body to hear and decide a particular kind of case.
- Tribunal: A special body, like a court but focused on one subject, set up to decide a certain type of dispute.
- Award: The final decision of a tribunal. In water cases, it says how much water each state gets and on what conditions.
- Official Gazette: The government's official publication. A decision printed here becomes legally effective.
- Upstream and downstream states: The upstream state is where the river flows first; the downstream state receives the water after it.
- TMC (thousand million cubic feet): A unit for measuring large amounts of water. 1 TMC is about 28.3 billion litres.
- Seventh Schedule: The part of the Constitution with three lists (Union, State, Concurrent) that divide law-making subjects between Parliament and state legislatures.
- Article 262 is in Part XI; 262(1) lets Parliament provide for adjudication; 262(2) lets Parliament bar the Supreme Court and other courts
- Entry 17, State List (water) is subject to Entry 56, Union List (inter-state rivers)
