IWT: India rejects ‘so-called’ arbitration award as ‘null and void’

The Indus Waters Treaty (IWT), brokered by the World Bank in 1960, is a cornerstone of India-Pakistan relations, often cited as a successful example of water diplomacy surviving major conflicts. The treaty allocates the 'Eastern Rivers' (Sutlej, Beas, Ravi) for India's unrestricted use, and the 'Western Rivers' (Indus, Jhelum, Chenab) largely to Pakistan, while allowing India limited run-of-the-river hydroelectric projects. India's recent actions—seeking 'review and modification' in September 2024 and declaring the treaty in abeyance post-Pahalgam terror attack—represent a drastic departure from its past adherence. The rejection of the Court of Arbitration award highlights India's insistence on the treaty's sequential dispute resolution mechanism, which prioritizes the Permanent Indus Commission and then a Neutral Expert before arbitration. India argues that parallel proceedings by a Neutral Expert and a CoA, as initiated by Pakistan, are legally untenable. This shift reflects India's strategy to use the IWT as a tool to pressure Pakistan over state-sponsored terrorism, moving away from viewing the treaty solely through a resource management lens.

From a legal and constitutional perspective, India's stance raises important questions about international treaty obligations. Article 51(c) of the Indian Constitution directs the State to 'foster respect for international law and treaty obligations.' While India is not formally abrogating the treaty, its actions push the boundaries of treaty law. The concept of pacta sunt servanda (agreements must be kept) is fundamental to international law. However, India may be implicitly invoking the doctrine of rebus sic stantibus (a fundamental change of circumstances) or relying on provisions within the Vienna Convention on the Law of Treaties (though India is not a party, it reflects customary international law) regarding material breach or impossibility of performance, particularly citing Pakistan's alleged persistent non-cooperation and the broader context of cross-border terrorism. UPSC aspirants should analyze the legal mechanisms for treaty modification or termination and the implications of unilateral actions on India's international standing as a responsible actor.

The Indus River Basin is vital for the agrarian economies of both India and Pakistan. The allocation under the Indus Waters Treaty is geographically significant; while India controls the headwaters, Pakistan relies heavily on the 'Western Rivers' for agriculture in its Punjab and Sindh provinces. India's rights to build run-of-the-river hydroelectric projects (like the Kishanganga and Ratle projects, which have been contentious) on the Western rivers must not involve significant water storage (pondage) that would disrupt the flow to Pakistan. The current CoA award specifically concerns 'maximum pondage.' India's geographic advantage as the upper riparian state gives it inherent leverage, but utilizing this leverage fully (e.g., stopping water flow) would require massive infrastructure development (dams, canals) that India currently lacks and would face severe international condemnation. Questions on the geographical features of the Indus system, the specific rivers allocated to each country, and the concept of upper/lower riparian rights are crucial for Prelims.
