A Treaty in Abeyance
The Indus Waters Treaty (IWT), brokered in 1960, is a foundational international agreement that serves as the lifeblood for hundreds of millions of people in Pakistan and India. For decades, it survived regional conflicts as a model of bilateral resource management. However, this stability was shaken in April 2025 when the Government of India unilaterally placed the treaty in “abeyance”, a move Pakistan and several international legal experts contend has no basis under the treaty’s terms.
Following the April 2025 Pahalgam attack, which India attributed to Pakistan-backed militants, a claim they have failed to provide evidence for, India suspended hydrological data-sharing protocols.
From Islamabad’s perspective, this amounts to “water-terrorism”. Pakistani officials describe the declaration of “abeyance” as a political weapon designed to exact severe economic and humanitarian tolls, and argue it violates established norms of international law and transboundary water sharing.
The Legal Debate Over India’s “Abeyance” Doctrine
India’s decision to hold the 65-year-old agreement in “abeyance” is contested, as the treaty’s text contains no expiration or unilateral withdrawal provision. International legal experts and Pakistani institutions have challenged India’s legal justifications. Article IX of the IWT sets up a detailed, escalatory mechanism for dispute settlement, and critics argue India is obligated to exhaust this mechanism before pursuing unilateral countermeasures. Pakistan maintains that by bypassing these mechanisms and declaring an “abeyance,” India’s actions do not survive legal scrutiny and constitute a violation of international law. India has not formally responded to these specific legal arguments, maintaining instead that changed circumstances justify its position.
The President of the World Bank, which serves as the treaty’s guarantor, has also weighed in:
“There is no provision in the treaty to allow it to be suspended. The way it (IWT) was drawn up, it either needs to be gone, or it needs to be replaced by another one. That requires the two countries to want to agree.”
Pakistan has cited this remark as further evidence that India’s position lacks a legal foundation.
Rhetoric Escalates: “Not a Single Drop”
Following the suspension of the treaty, rhetoric from Indian officials has hardened considerably. The most notable development occurred on the 9th of June 2026, when India’s Union Minister of Water, C.R. Patil, made a pointed public statement directed at Pakistan’s water supply.
Speaking to the ANI news agency, Patil stated: “It is certain, not a single drop of water will go (to Pakistan) in the coming years”. The minister indicated that this position was being developed based on direct “directives” from Prime Minister Narendra Modi. Commentators and Analysts have classed this as an explicit threat to weaponise the basic human right to water as a tool of pressure against a downstream neighbour, and warn it represents a dangerous escalation in how water resources are discussed in the bilateral relationship.
Infrastructure Projects on the Western Rivers
India has continued to advance infrastructure projects on the Western Rivers (Indus, Jhelum, and Chenab), which are allocated to Pakistan under the IWT. Pakistan views these projects as provocative and as part of a broader doctrine of water denial.
- The Chenab-Beas Diversion Scheme: India’s state-owned National Hydroelectric Power Corporation (NHPC) issued a tender notice in May 2026 for the Chenab-Beas Link Tunnel Project. This engineering scheme, estimated at Rs 5,000 crore, is designed to divert water from the Chenab River eastward into India’s Beas basin. Pakistan has raised concerns that the project alters natural basin hydrology and poses risks to the Himalayan region.
- Sediment Flushing at Salal: In early 2026, India initiated “sediment removal” operations at the Salal Hydroelectric Power Station on the Chenab River. Pakistan contends these operations bypassed safety protocols designed to prevent downstream flooding. Indian officials cited their unilateral “termination of the Indus Waters Treaty” as their justification.
Pakistan’s Recourse to International Arbitration
In response to India’s actions, Pakistan pursued its case through the Permanent Court of Arbitration (PCA) in The Hague, securing two notable legal victories.
- Rejection of “Abeyance”: In June 2025, the PCA issued a binding Supplemental Award on Competence, stating that India’s claim of “abeyance” does not strip the international tribunal of its legal authority to hear the case.
- The Maximum Pondage Ruling: On 15 May 2026, the PCA delivered a ruling concerning “maximum pondage”, upholding Pakistan’s technical parameters and placing limits on India’s water-control ability on the Western Rivers.
India did not participate in the PCA proceedings, having maintained throughout that the court lacks jurisdiction following the treaty’s suspension. Following the May 2026 ruling, India’s Ministry of External Affairs declared the award “null and void,” reiterating its position that the treaty remains in abeyance. India’s non-participation and rejection of the ruling has been characterised as a disregard for international legal norms.
Pakistan’s Diplomatic Response
Pakistan views the weaponisation of the Indus basin as an existential threat and has stated that any attempt by India to alter or block the flow of cross-border waterways would be treated as an “act of war”.
Pakistan has elevated the dispute to international forums. Pakistan’s UN Ambassador Asim Iftikhar Ahmad told the United Nations Security Council in early 2026 that India’s actions constitute a “serious violation of international legal obligations,” carrying “far-reaching humanitarian, environmental, and peace and security implications” for the region. On World Water Day in March 2026, Pakistan’s President Asif Ali Zardari criticised India for disrupting data-sharing arrangements under the agreement.
Strategic Implications
The dispute over the IWT’s status, India’s rejection of the PCA’s authority, and the accelerating pace of infrastructure development on the Western Rivers represent a significant deterioration in India-Pakistan relations on water-sharing, an arrangement that had previously proven resilient through multiple wars and periods of hostility. Pakistan frames India’s position as that of a “rogue riparian state” destabilising the environmental and strategic security of South Asia and threatening a downstream neighbour’s water security; India maintains its actions are a justified response to changed security circumstances. With the treaty’s future status unresolved and both sides entrenched, the dispute carries significant implications for regional stability, and observers have called for the issue to be insulated from broader political and security tensions to avoid further escalation.
