India has rejected a ruling from the Court of Arbitration regarding the Indus Waters Treaty, asserting that the court was improperly constituted and that its decisions lack legal validity.
On May 15, 2026, India’s Ministry of External Affairs (MEA) issued a resolute denial of the recent ruling by the Court of Arbitration (CoA), which was established under the Indus Waters Treaty (IWT) of 1960. MEA spokesperson Randhir Jaiswal characterized the ruling as “null and void” during a media briefing, reiterating India’s longstanding position on the legitimacy of the court.
According to Jaiswal, the CoA’s recent award pertained to “maximum pondage supplemental to the award on issues of general interpretation of the Indus Waters Treaty.” He emphasized that India categorically rejects this latest ruling, as it has done with all prior decisions from what it deems the “illegally constituted” CoA. He further noted that India has never recognized the court’s establishment and maintained that any decisions made by it carry no legal weight. Jaiswal reaffirmed that India’s decision to place the IWT in abeyance remains in effect.
Historical Context of the Indus Waters Treaty
The Indus Waters Treaty, signed on September 19, 1960, between India and Pakistan, was designed to regulate the allocation and use of water resources from the Indus River system. The treaty has been a crucial framework for managing water resources between the two nations, which have historically had a complex relationship marked by both cooperation and conflict. The treaty allocates the waters of six rivers in the Indus river basin—Indus, Jhelum, Chenab, Ravi, Beas, and Sutlej—primarily to Pakistan, while allowing India to utilize the rivers for irrigation and hydroelectric power generation.
India’s Suspension of Treaty Obligations
In a significant development, following a terrorist attack in Pahalgam in 2025, India invoked its rights under international law to suspend its obligations under the IWT until Pakistan credibly renounces its support for cross-border terrorism. This suspension has profound implications for water management and diplomatic relations between the two countries, especially given the ongoing tensions surrounding terrorism and military activities along their borders.
The MEA’s position is that, “Until such time that the Treaty is in abeyance, India is no longer bound to perform any of its obligations under the Treaty. No Court of Arbitration, much less this illegally constituted arbitral body which has no existence in the eye of law, has the jurisdiction to examine the legality of India’s actions in exercise of its rights as a sovereign.” This marks a pivotal moment in India-Pakistan relations, raising questions about the future of the treaty and the stability of water-sharing agreements.
Previous Decisions by the Court of Arbitration
In 2025, the MEA had previously criticized the CoA for issuing a supplemental award concerning the Kishenganga and Ratle hydroelectric projects, located in the Indian Union Territory of Jammu and Kashmir. The MEA characterized the court’s actions as lacking legitimacy, reiterating India’s non-recognition of the court’s authority. Jaiswal had previously stated, “India has never recognized the existence in law of this so-called Court of Arbitration, and India’s position has all along been that the constitution of this so-called arbitral body is in itself a serious breach of the Indus Waters Treaty and consequently any proceedings before this forum and any award or decision taken by it are also for that reason illegal and per se void.”
India’s Critique of Pakistan’s Actions
India’s rejection of the CoA’s ruling occurs against a backdrop of ongoing tensions with Pakistan, particularly regarding issues of terrorism and military confrontations. The MEA has consistently accused Pakistan of exploiting international forums to evade accountability for its alleged role as a “global epicenter of terrorism.” Jaiswal remarked that Pakistan’s reliance on this arbitration mechanism is indicative of a broader pattern of deception and manipulation within international circles. He stated, “Pakistan’s resort to this fabricated arbitration mechanism is consistent with its decades-long pattern of deception and manipulation of international forums.”
Implications for Regional Stability
This latest assertion from India underscores the complex geopolitical dynamics in South Asia, particularly concerning water resources and national security. The future of the Indus Waters Treaty remains uncertain, with potential ramifications for regional stability and bilateral relations. The treaty has historically been a point of contention, often used as leverage in broader geopolitical negotiations between India and Pakistan. As both nations continue to navigate these contentious issues, the implications for water-sharing agreements and mutual cooperation become increasingly significant.
The ongoing rejection of the CoA’s authority by India not only impacts the future of the IWT but also raises questions about the efficacy of international arbitration in resolving conflicts between sovereign nations. As India maintains its stance against the CoA, the possibility of further escalations in water disputes looms, particularly given the increasing pressures of climate change and water scarcity in the region.
As the geopolitical landscape evolves, the international community will be watching closely to see how India and Pakistan address these critical issues, as their decisions will likely have far-reaching consequences for South Asia’s stability and security.
