Critically evaluate the effectiveness of negotiated MoUs versus tribunal adjudication under the Inter-State River Water Disputes Act, 1956, in resolving river water conflicts.

Article 262 bars courts from inter-state river disputes, vesting adjudication in tribunals under the Inter-State River Water Disputes Act, 1956 [1]. Yet the 2026 Bihar–Jharkhand MoU on the Sone settled a 25-year dispute for which Bihar had sought a tribunal in 2013 [2][3] — showing negotiation and adjudication as complementary, not rival, routes.

Merits of negotiated MoUs

• Speed and finality: the Sone MoU closed a bifurcation-era dispute in a single sitting, whereas the tribunal reference sought since 2013 never materialised [2][3].
• Ownership: consent-based settlements are self-enforcing; the Bansagar Agreement (1973) among MP, UP and undivided Bihar apportioning Sone waters has held for five decades [4].
• Institutional platform: Zonal Councils under the States Reorganisation Act, 1956 give a standing forum for such bargaining; the 27th Eastern Zonal Council took up Indrapuri, Masanjore and Taiyabpur issues [5][6].
• Package deals: negotiators can trade across irrigation, power and drinking-water needs; a tribunal can only apportion water.

Limits of MoUs

• Depend on political alignment and personalities; deadlock is the default where governments differ.
• Weak enforceability and vulnerability to reopening after regime change.
• Risk of excluding basin-wide stakeholders and downstream/ecological interests.

Merits and limits of tribunal adjudication

• Provides a binding, reasoned award with the force of a Supreme Court decree, protecting weaker riparians where bargaining power is unequal.
• But is chronically slow — the ISRWD (Amendment) Bill, 2019 itself proposed a Disputes Resolution Committee to settle disputes within a year precisely because adjudication had become protracted [7].
• Awards lacking political buy-in invite non-compliance and litigation, as India's long-running tribunals show.

Effectiveness, therefore, is sequential rather than either/or: negotiation should be the first resort, with adjudication as the credible backstop that makes bargaining serious. Institutionalising the DRC route, strengthening river basin data-sharing, and using Zonal Councils proactively would let the Sone model be replicated — advancing cooperative federalism and SDG-6 water security together.
