What happened

Inter-state water disputes are a classic UPSC case study testing your understanding of federalism's friction points. The Mekedatu issue isn't just about water; it's a live test of constitutional mechanisms like Article 262 and the efficacy of quasi-judicial tribunals in resolving resource conflicts amid growing water scarcity and regional politics.

Water Governance Models: India vs. Australia

FeatureIndia's ApproachAustralia's Model
Institutional BodyAd-hoc tribunals for specific disputes.Permanent statutory body (e.g., Murray-Darling Basin Authority).
Management ScopePrimarily dispute resolution; lacks unified River Basin Organization (RBO) structure.Holistic, basin-wide planning, management, and compliance.
NatureReactive and fragmented.Proactive and integrated.

Smart Gravity Note

The core of this issue for Prelims lies in the constitutional and statutory provisions governing inter-state water disputes.

Focus on Article 262, which empowers Parliament to create laws for adjudication and explicitly bars the Supreme Court's jurisdiction over such disputes once a tribunal is established.

Understand the Inter-State River Water Disputes Act, 1956, which is the law Parliament enacted under Article 262.

Differentiate between the roles of a tribunal (adjudication), the Supreme Court (interpretation of law, special leave petitions), and post-award bodies like the Cauvery Water Management Authority (implementation). The distinction between these institutions is a frequent testing area.

The key takeaway is that under Article 262, Parliament can oust the jurisdiction of all courts, including the Supreme Court, regarding inter-state water disputes, though the SC has retained jurisdiction under Article 136 (SLP).

◎ In Simple Words

Imagine two states, Karnataka and Tamil Nadu, sharing water from the Cauvery river like siblings sharing a big bottle of juice. Karnataka wants to build a small dam (Mekedatu) to store some water for its cities. Tamil Nadu, which is downstream, worries this will mean less water for its farmers. Even though a special court (tribunal) and the Supreme Court have already set rules for sharing, Tamil Nadu is now asking for a new referee, which complicates things further. This is a big argument about fair sharing of a precious resource.
