"Mahanadi Water Dispute: Tribunal Pressure Revives Bilateral Settlement Talks"
Article 262
Constitutional provision empowering Parliament to adjudicate inter-state river water disputes, barring Supreme Court jurisdiction if Parliament so provides.
ISRWD Act, 1956
Inter-State River Water Disputes Act; provides for ad hoc Tribunals whose awards have the force of a Supreme Court decree.
Inter-state river water disputes are a structural tension embedded in India's constitutional design. Entry 17 of the State List (Seventh Schedule) designates water — including irrigation, canals, drainage, and embankments — as a state subject, giving states primary jurisdiction over water within their borders. However, Entry 56 of the Union List empowers Parliament to regulate and develop inter-state rivers to the extent declared expedient in the public interest, creating an inherent jurisdictional overlap wherever rivers cross state boundaries.
Article 262 of the Constitution specifically authorises Parliament to adjudicate disputes relating to the use, distribution, or control of inter-state river waters, and crucially bars the Supreme Court and other courts from exercising jurisdiction over such disputes if Parliament so provides. Parliament operationalised this through the Inter-State River Water Disputes (ISRWD) Act, 1956, which provides for the constitution of ad hoc Tribunals when negotiation between states fails. Tribunal awards, once published in the Official Gazette, carry the force of a decree of the Supreme Court. The River Boards Act, 1956, passed alongside it, envisaged integrated basin management but has never been operationally invoked.
The Mahanadi — India's eighth-longest river at 851 km — originates from the Amarkantak hills of the Bastar Plateau in Chhattisgarh's Dhamtari district and flows approximately 494 km through Odisha before draining into the Bay of Bengal. Odisha's grievance centres on upstream barrages and reservoirs constructed by Chhattisgarh, which it alleges have reduced non-monsoon downstream flows, threatening the irrigation, drinking water, and ecology of the Mahanadi delta — one of India's most agriculturally productive regions.
The Mahanadi dispute crystallised after Chhattisgarh was carved out of Madhya Pradesh in 2000 and began charting its own development trajectory, with the river central to its irrigation, drinking water, and industrial needs. For decades, Odisha had relied on the Hirakud Dam in Sambalpur district — one of Asia's longest earthen dams — to regulate floods, generate hydroelectricity, and sustain irrigation networks. The conflict emerged visibly in the early 2010s when Odisha observed a significant decline in non-monsoon river flows and attributed this to Chhattisgarh's construction of over 500 anicuts and 30 barrages upstream. Chhattisgarh countered that 52.9% of Mahanadi's total catchment and 89.9% of the catchment up to Hirakud lies within its territory, asserting a proportionate right to use the water.
Odisha filed a formal complaint with the Centre under Section 3 of the ISRWD Act, 1956 in November 2016. …
