Article 262(1)

Article 262(1) of the Constitution of India vests Parliament with the exclusive power to legislate for the adjudication of disputes between the Union and a State, or between two or more States, concerning the use, distribution or control of the waters of any inter‑State river or river valley. By expressly barring courts from entertaining such matters, the provision creates a specialised, legislative‑driven pathway for resolving water conflicts—an issue that has repeatedly sparked political tension across the subcontinent. The clause therefore underpins the legal architecture that has produced a series of inter‑State water tribunals, the most prominent being the Inter‑State Water Disputes Act, 1956, enacted under its authority.

Historical Background

The framers inserted Article 262 into the Constitution during the 1949 debates of the Constituent Assembly, motivated by the experience of pre‑Independence river disputes such as the Punjab‑Sindh water question. Dr. B.R. Ambedkar argued that ordinary courts were ill‑suited to handle the technical and political complexities of river‑water allocation, recommending a distinct legislative mechanism. When the Constitution came into force on 26 January 1950, Article 262(1) thus became the constitutional anchor for a future statutory regime.

Legislative Mechanism

Parliament exercised the power conferred by Article 262(1) through the Inter‑State Water Disputes Act, 1956 (Act No. 34 of 1956). Under Section 3 of the Act, either the Union government or a State may refer a dispute to the central government, which may then constitute a tribunal under Section 4. The tribunal consists of three members: a chairperson appointed by the Union, and one member each nominated by the disputing States, a structure designed to balance federal interests. Sections 6 and 7 empower the tribunal to summon documents, issue commissions of inquiry, and render a binding award, which, under Section 8, is enforceable as a decree of the Supreme Court.

The 1996 amendment (Act 44 of 1996) introduced the concept of a permanent tribunal to address the chronic delays in forming ad‑hoc bodies, but the provision was later superseded by the 2002 amendment (Act 44 of 2002), which formally established a standing Inter‑State Water Dispute Tribunal (ISWDT). The ISWDT retains the three‑member composition but operates continuously, allowing quicker referral and adjudication of emerging disputes.

Key Provisions of the 1956 Act

Section 3 delineates the procedure for referral, requiring a formal request signed by the concerned State’s chief minister or the Union’s Minister of Water Resources. Section 4 specifies the appointment timeline: the chairperson must be a retired judge of the Supreme Court or a High Court, while the other members are selected for their expertise in hydrology, engineering or law. Section 6 grants the tribunal authority to determine the quantum of water, the timing of releases, and the construction of storage structures, with the power to issue interim orders to prevent waste or damage. Section 7 makes the award final and binding, subject only to a limited review by the Supreme Court on questions of jurisdiction or constitutional validity.

Notable Tribunals and Outcomes

The Krishna Water Dispute Tribunal (1990) apportioned 1,200 cubic metres per second (cumecs) among Andhra Pradesh, Karnataka, Maharashtra and Tamil Nadu, establishing a precedent for seasonal allocation formulas. The Cauvery Water Dispute Tribunal (1997) allocated 409 cumecs to Karnataka and 270 cumecs to Tamil Nadu, a figure later affirmed by the Supreme Court in 2018 after extensive litigation. The Godavari Water Dispute Tribunal (2002) divided the river’s flow among Maharashtra, Karnataka, Telangana and Andhra Pradesh, introducing a “minimum assured flow” concept that has been replicated in later agreements. These awards, though technically binding, have often required political negotiation for implementation, highlighting the interplay between legal adjudication and executive action.

Current Status and Challenges

As of 2024, several high‑profile disputes remain unresolved, including the Brahmaputra water sharing between Assam and the Union, and renewed contention over Narmada allocations after the 2021 amendment to the Narmada Water Dispute Act. Critics argue that the limited scope for judicial review under Article 262(1) can impede corrective oversight, while the time‑lag in constituting tribunals—averaging
