Discuss the institutional mechanism for resolving inter-state river water disputes in India. Examine the effectiveness of bodies like the Cauvery Water Management Authority in the Cauvery dispute.

Article 262 bars ordinary courts from inter-state river water disputes, leaving adjudication to a parliamentary mechanism, while Entry 56 of the Union List empowers Parliament to regulate inter-state rivers. The framework is legally sound but its implementation tier remains contested, as the Cauvery dispute shows.

The institutional mechanism

• Adjudicatory tier: the Inter-State River Water Disputes Act, 1956 provides for tribunals on state request — the Cauvery Water Disputes Tribunal (1990) gave its award in 2007, modified by the Supreme Court in 2018, apportioning water among Karnataka, Tamil Nadu, Kerala and Puducherry [3].
• Implementation tier: the Cauvery Water Management Scheme (S.O. 2236(E), 1 June 2018) created the CWMA for overall management and the CWRC for real-time release recommendations [2].
• Reform tier: the ISRWD (Amendment) Bill, 2019 proposed a Disputes Resolution Committee for pre-tribunal settlement, a single tribunal with benches, and tighter timelines to cut pendency [1].

Effectiveness of CWMA — strengths

• Converts episodic litigation into year-round regulation: it rejected Karnataka's appeal and ordered 3,500 cusecs/day to Tamil Nadu for 15 days from 29 July 2026 [4].
• Basin-wide composition (chairman, whole-time and Central members, plus all four basin states) institutionalises continuous dialogue [2].
• Deriving authority from the 2018 verdict, its orders carry the weight of contempt, not mere persuasion [3].

Limitations

• No independent enforcement arm — compliance rests on the state; Karnataka responded with an appeal move and an all-party meeting rather than release [4].
• Absence of an agreed distress-sharing formula for deficit years reproduces conflict every weak monsoon.
• Weak jointly-trusted telemetry and flow data, so each order is disputed on facts.
• Orders become political flashpoints — protests at the KRS reservoir, Mandya — displacing long-term conservation planning [4].

The Cauvery experience shows the mechanism is robust in adjudication but thin in enforcement and hydrological trust. A statutory distress-sharing formula, jointly audited telemetry, and full operationalisation of the 2019 reforms would let such authorities function as instruments of cooperative federalism rather than arenas of contest.
