Inter-State River Water Disputes Act 1956

Topic: Federalism and Centre-State Relations · NCERT: Class 11, Ch 7 "Federalism"

Meaning

The Inter-State River Water Disputes Act 1956 (ISRWD Act) is the law Parliament made under Article 262. Under it, the Centre sets up a separate tribunal (a special body that hears and decides a case) for each quarrel between states over an inter-state river. Once the tribunal's award (final decision) is published, it has the same force as a Supreme Court order.

It matters because water disputes are more serious than border disputes. They affect drinking water and farming, so voters in every state involved feel the result. The Act is the main legal route for settling these disputes.

Explanation

Why the Act exists

• Water is mainly a state subject.
• "Water" is in the State List (Entry 17, List II).
• Entry 17 is subject to Entry 56 of the Union List, which lets Parliament regulate inter-state rivers in the public interest.

• The ISRWD Act and the River Boards Act are both based on Entry 56.

• Article 262 gives Parliament two powers.

• Art. 262(1): Parliament may make a law to adjudicate (formally decide) disputes over the use, sharing or control of an inter-state river or river valley.

• Art. 262(2): Parliament may also make a law that stops the Supreme Court and every other court from hearing such disputes.

• NCERT's view (Class 11, Ch 7 "Federalism"): these quarrels look legal but are really political. So negotiation (talks between the states) matters as much as adjudication (a tribunal or court deciding).

How the procedure works, step by step

Step	What happens	Time limit / rule
1	A state government sends a complaint to the Centre (s.3)	—
2	The Centre tries to settle it through talks	—
3	If talks fail, the Centre sets up a Water Disputes Tribunal (s.4)	Within 1 year of the request (added by the 2002 amendment)
4	The tribunal investigates and gives its award (s.5)	3 years, extendable by 2 years (2002 amendment)
5	The states or the Centre may ask the tribunal to clarify the award (s.5(3))	Within 3 months of the award
6	The Centre publishes the award in the Official Gazette	It then has the same force as an order or decree of the Supreme Court (s.6(2), added in 2002)
7	The Centre may frame a scheme to carry out the award (s.6A)	—

• Ad hoc tribunals: a new tribunal is set up for each river dispute. There is no permanent tribunal.
• A tribunal is usually headed by a sitting Supreme Court judge.

Limits: the court bar and its gaps

• Section 11: no court, including the Supreme Court, can hear a water dispute that has been referred to a tribunal. This uses the power given by Art. 262(2).
• Article 131 gives the Supreme Court original jurisdiction (it hears the case first) over disputes between the Centre and states, or between states. Art. 131 is subject to Art. 262.
• Courts still have a role:
• Art. 136 (special leave to appeal, which lets the Supreme Court hear an appeal against any court's or tribunal's decision). The Cauvery appeals against the 2007 award were heard this way (2016-18).

• The Supreme Court has held that Section 11 stops it from reopening the water-sharing dispute itself. It does not stop the Court from checking whether a tribunal's award is lawful.

• Weaknesses seen in practice:

• Tribunals are slow. Cauvery took 17 years (1990 to 2007).
• States can ignore an award or reopen it through appeals.

In the Constitution and practice

• Legal base: Article 262, Entry 56 of the Union List, and the ISRWD Act 1956. The 2002 amendment added the 1-year deadline to set up a tribunal, the 3 + 2 year deadline for the award, and the rule that a published award has Supreme Court force.
• Who uses it: a state government complains, the Union government sets up the tribunal and publishes the award, and the tribunal decides.
• Tribunals set up under the Act:

Tribunal	States	Constituted	Award
Krishna I	Maharashtra, Karnataka, Andhra Pradesh	1969	1973 report; final 1976
Godavari	Maharashtra, AP, Karnataka, MP, Odisha	1969	1980
Narmada	Gujarat, MP, Maharashtra, Rajasthan	1969	1979
Ravi-Beas (Eradi Tribunal)	Punjab, Haryana, Rajasthan	1986	1987 report; further reference pending
Cauvery	Karnataka, Tamil Nadu, Kerala, Puducherry	1990	2007 (changed by the Supreme Court in 2018)
Krishna II	Karnataka, Maharashtra, AP (now also Telangana)	2004	2010 report; further report 2013
Vansadhara	Andhra Pradesh, Odisha	2010	2017
Mahadayi (Mandovi)	Goa, Karnataka, Maharashtra	2010	2018
Mahanadi	Odisha, Chhattisgarh	2018	Still hearing (verify current)

• Five tribunals still exist, according to the Jal Shakti Ministry: Ravi-Beas, Vansadhara, Mahadayi, Mahanadi and Krishna [4].
• Mahanadi: the Union Cabinet approved this tribunal after Odisha complained about upstream barrages in Chhattisgarh [5].
• Krishna II after 2014: Andhra Pradesh was split in 2014. In 2023 the Cabinet gave Krishna Tribunal-II further terms of reference (the exact questions it must answer) under the ISRWD Act, to divide water between Andhra Pradesh and Telangana [6].
• Cauvery: tribunal award, then Supreme Court appeal:
• The 2007 award gave Tamil Nadu 419 TMC (thousand million cubic feet), Karnataka 270, Kerala 30 and Puducherry 7.
• State of Karnataka v. State of Tamil Nadu (16 February 2018): hearing appeals under Art. 136, the Supreme Court raised Karnataka's share to 284.75 TMC and cut Tamil Nadu's to 404.25 TMC. It said drinking water comes first and called inter-state rivers a national asset (no single state owns one).

• The Court ordered the Centre to frame a scheme under s.6A. This created the Cauvery Water Management Authority (CWMA) in June 2018, helped by the Cauvery Water Regulation Committee (CWRC).

• Narmada (1979 award): shared the water and fixed the height of the Sardar Sarovar dam. The Narmada Bachao Andolan showed that a tribunal can settle a dispute between states, but not one between a state and its displaced people.

• Ravi-Beas and the SYL canal:
• The Eradi Tribunal (1986) came out of the Rajiv Gandhi-Longowal Punjab Accord (24 July 1985).
• Punjab passed the Punjab Termination of Agreements Act 2004 to cancel its water-sharing agreements.

• In re Punjab Termination of Agreements Act, 2004 (10 November 2016): in an advisory opinion under Art. 143 (the President asking the Supreme Court for its view), the Court said the Act was unconstitutional. A state cannot cancel inter-state agreements on its own.

• Mullaperiyar was settled without a tribunal. In State of Tamil Nadu v. State of Kerala (2014), a Constitution Bench heard an original suit. It struck down Kerala's 2006 dam-safety law and upheld the 142-foot water level.

• Reform: ISRWD (Amendment) Bill 2019:
• It was introduced in the Lok Sabha on 25 July 2019 and passed by the Lok Sabha on 31 July 2019 [3].
• It would replace ad hoc tribunals with one permanent tribunal that has several benches [2].
• That tribunal would have a Chairperson, a Vice-Chairperson, three judicial members and three expert members [2][3].
• A Disputes Resolution Committee (DRC) would first try to settle the dispute through talks, within 1 year, extendable by 6 months [2][3].
• The award would be due in 2 years, extendable by 1 year [3].
• An agency named by the Centre would keep a data bank for each river basin [3].
• Status: under Art. 107(5), a bill pending in the Rajya Sabha lapses (dies) when the Lok Sabha is dissolved. So the bill would have lapsed when the 17th Lok Sabha was dissolved in 2024 (verify current).

Don't confuse with

• Article 262 vs ISRWD Act: Article 262 only allows Parliament to make a law and to bar the courts. The ISRWD Act is the actual law, and its Section 11 is what bars the courts.
• Article 131 (original suit): the Supreme Court decides Centre-state or state-state disputes directly. It does not apply to water disputes that Parliament has kept out of court under Art. 262. Mullaperiyar went through the courts, not a tribunal.
• River Boards Act 1956: also based on Entry 56. It allows advisory River Boards, not tribunals that decide disputes. No board has ever been set up, so experts call it a "dead letter" (a law that exists but is never used).
• 2019 Bill vs 1956 Act: one permanent tribunal with an award in 2 + 1 years [2][3], against ad hoc tribunals with an award in 3 + 2 years. The Bill was passed only by the Lok Sabha.

Prelims Hooks

• Art. 262(2): Parliament may bar the Supreme Court from water disputes. ISRWD Act s.11 does this. Even so, the Supreme Court heard the Cauvery appeals under Art. 136.
• 2002 amendment: tribunal within 1 year of the request; award in 3 + 2 years; a published award has the force of a Supreme Court decree (s.6(2)).
• Cauvery 2018: Tamil Nadu 419 → 404.25 TMC; Karnataka 270 → 284.75 TMC; Kerala (30) and Puducherry (7) unchanged. Rivers called a "national asset". CWMA was set up under s.6A.
• Trap: Mullaperiyar was not decided by a tribunal. TN v. Kerala (2014) was an original suit in the Supreme Court.
• Tribunal–states pairs: Mahanadi = Odisha and Chhattisgarh (2018) [5]; Vansadhara = Andhra Pradesh and Odisha; Mahadayi = Goa, Karnataka and Maharashtra; Eradi = Ravi-Beas (1986).
• 2019 Bill: one permanent tribunal; DRC with 1 + ½ years; award in 2 + 1 years [2][3]. Passed only by the Lok Sabha [3].

Mains Points

• Adjudication vs negotiation:
• Tribunals take decades (Cauvery took 17 years). Their awards are often ignored, as Punjab did with SYL, or reopened through appeals.
• Water is a political issue, so a lasting settlement needs political agreement and the Centre's help, not just a legal order.

• The DRC in the 2019 Bill builds talks into the process before adjudication [2].

• Institutional reform:

• A permanent tribunal with fixed deadlines and a river-basin data bank would make the process faster and more open [2][3].
• Unused tools could also help: the River Boards Act, the Inter-State Council (Art. 263) and Zonal Councils.

• Bodies like the CWMA show that carrying out an award needs a standing body, not just the award itself.

• Federal principle:

• The Supreme Court has said rivers are a national asset and drinking water comes first (2018).
• It has also said a state cannot cancel inter-state agreements on its own (2016).
• Together these limit "state ownership" of water and support cooperative federalism (the Centre and states working together).
