Examine the institutional mechanism for adjudicating and implementing inter-state river water sharing in India, citing the Cauvery Water Management Authority.

Water is a State subject (Entry 17), but regulation of inter-State rivers falls to the Union (Entry 56), and Article 262 lets Parliament provide for adjudication of such disputes while barring court jurisdiction. India's mechanism thus rests on two distinct legs — adjudication by tribunals and implementation by river authorities — both visible in the Cauvery.

Leg 1: Adjudication

• The Inter-State River Water Disputes Act, 1956 allows a State to seek reference of a dispute to an ad hoc tribunal, whose award, once notified, binds the parties [1].
• The Cauvery Water Disputes Tribunal (1990) gave its final award in 2007; the Supreme Court modified it on 16 February 2018, fixing shares of Tamil Nadu 404.25 TMC, Karnataka 284.75 TMC, Kerala 30 TMC and Puducherry 7 TMC [2].

Leg 2: Implementation

• Awards fix annual volumes, not daily releases. Section 6A therefore empowers the Centre to frame a scheme; under it the Cauvery Water Management Authority (CWMA) and Cauvery Water Regulation Committee (CWRC) were notified on 1 June 2018 to give effect to the modified award [2].
• CWRC monitors storage and flows in real time and recommends releases; CWMA, a statutory quasi-judicial body under the Ministry of Jal Shakti, issues binding directions and records them through periodic meetings [3].

Persisting weaknesses

• Delay: the Cauvery took nearly three decades from tribunal reference to final adjudication [1].
• Enforcement deficit: CWMA depends on State cooperation; deficit monsoons force distress-sharing without an agreed shortfall formula, reviving agrarian and political friction.
• Reform is pending through the Inter-State River Water Disputes (Amendment) Bill, 2019 — a single permanent tribunal, a pre-litigation Dispute Resolution Committee, and a two-year decision deadline [4].

The Cauvery shows that adjudication settles entitlements while authorities like CWMA operationalise them; the gap lies in enforcement and timeliness. Institutionalising a permanent tribunal, transparent basin-wide data and negotiated deficit-sharing would convert a litigative model into genuinely cooperative federalism.
