India Rejects Hague Court’s Indus Waters Treaty Ruling, Citing Lack of Jurisdiction

India has rejected the Hague-based ruling on the Indus Waters Treaty, arguing that the Court of Arbitration that issued the decision has no jurisdiction over India. The Ministry of External Affairs has maintained that New Delhi does not recognise the tribunal and that its decision to keep the treaty in abeyance remains unchanged.

The development is significant because the dispute is no longer limited to technical questions about dams, river flows or hydroelectric projects. It now involves a much deeper disagreement over which legal mechanism has the authority to interpret the Indus Waters Treaty, whether India can place the agreement in abeyance, and how the shared river system should be managed amid a severe deterioration in India-Pakistan relations.

Why India rejected the Indus Waters Treaty ruling

India’s principal objection is jurisdiction. New Delhi does not accept that the Court of Arbitration has the authority to adjudicate the dispute in the manner pursued by Pakistan.

The MEA has described the body as an “illegally-constituted” and “so-called Court of Arbitration” and reiterated that India has never recognised its legal existence. As a result, New Delhi does not consider the tribunal’s pronouncements binding on India.

“India has never recognised the existence in law of this illegally-constituted and so-called Court of Arbitration.”

This is an important distinction. India is not simply saying that it disagrees with the tribunal’s conclusions. It is challenging the legal foundation of the proceedings themselves.

What is the Indus Waters Treaty?

The Indus Waters Treaty was signed by India and Pakistan in 1960, with the World Bank playing an important role in facilitating the agreement. It established rules for the use and management of the waters of the Indus river system.

The treaty divides the six major rivers broadly into two groups. India received primary use of the eastern rivers — Ravi, Beas and Sutlej — while Pakistan received primary use of the western rivers — Indus, Jhelum and Chenab.

However, the arrangement is not an absolute division in which India has no rights over the western rivers. The treaty permits India certain uses, including hydroelectric power generation, subject to detailed technical conditions.

Those conditions have become a recurring source of disagreement between New Delhi and Islamabad.

Why Indian hydroelectric projects are at the centre of the dispute

Several Indian hydroelectric projects in Jammu and Kashmir have been challenged by Pakistan over the years. The concern in Islamabad is that the design and operation of upstream projects could influence the timing or volume of water reaching Pakistan.

India has consistently argued that its projects are permitted under the Indus Waters Treaty and that the agreement gives it the right to develop hydropower resources within prescribed technical limits.

The dispute has therefore involved questions about dam design, water storage, pondage, spillways, drawdown levels and downstream flows.

But the disagreement has become more complicated because India and Pakistan have also disagreed about which dispute-resolution mechanism should be used.

How the Indus Waters Treaty resolves disputes

The treaty contains a detailed system for handling disagreements. Depending on the nature of a dispute, the framework involves institutions and procedures including the Permanent Indus Commission, a Neutral Expert and a Court of Arbitration.

In theory, this system was designed to prevent technical disagreements from escalating into political crises.

In practice, the two countries have increasingly disagreed about the interpretation and sequencing of these mechanisms.

That has transformed a technical water dispute into a legal dispute about the dispute-resolution process itself.

The central legal disagreement

The current confrontation can be understood through two competing positions.

India’s position is that the Court of Arbitration was improperly constituted and lacks jurisdiction. Consequently, New Delhi does not accept its decisions as legally binding.

The arbitration panel’s position is that the Indus Waters Treaty remains legally operative and that the tribunal has authority to consider the issues brought before it under the treaty’s dispute-resolution provisions.

This creates an unusual legal situation. The tribunal considers itself competent to issue decisions, while India does not recognise the tribunal’s jurisdiction in the first place.

India’s decision to keep the treaty in abeyance

India announced that it was putting the Indus Waters Treaty in abeyance in April 2025, following the deadly terror attack in Pahalgam in Jammu and Kashmir.

New Delhi linked the attack to Pakistan-based elements, while Pakistan rejected India’s allegations. The incident was followed by a sharp deterioration in bilateral relations.

India subsequently argued that cooperation under the treaty could not be considered separately from the broader security relationship between the two countries.

The arbitration process has taken a different position, maintaining that India’s unilateral decision to place the treaty in abeyance does not remove the agreement’s legal force.

This difference raises a wider question about the relationship between international treaty obligations and national security considerations.

What did the Hague-based Court of Arbitration say?

The Court of Arbitration has maintained that the Indus Waters Treaty remains in force and that India’s unilateral decision to place it in abeyance does not provide a legal basis for removing the treaty’s obligations.

The panel has also dealt with interim measures relating to India’s Ratle hydroelectric project in Jammu and Kashmir.

For India, however, the central issue remains jurisdiction. Because New Delhi rejects the tribunal’s legal standing in the proceedings, it also rejects the authority of the tribunal to impose obligations on India through its rulings.

Important clarification: this is not an ICJ ruling

The phrase “Hague court” can cause confusion because several international legal institutions are based in or associated with The Hague.

The body involved here is a Court of Arbitration operating within the Permanent Court of Arbitration framework. It is not the International Court of Justice, which is the principal judicial organ of the United Nations.

The distinction is important because the two institutions have different legal foundations, procedures and functions.

The present proceedings arise from the dispute-resolution provisions of the Indus Waters Treaty between India and Pakistan.

Timeline of the Indus Waters Treaty dispute

Why the dispute matters beyond one court ruling

The latest confrontation matters because the Indus river system is strategically important to both countries.

For Pakistan, the rivers covered by the treaty are central to irrigation, agriculture, drinking water and the wider economy. For India, the western Himalayan rivers represent an important source of hydropower and potential regional infrastructure development.

That makes water management inseparable from questions of energy security, food security, regional development and national sovereignty.

The dispute also demonstrates how infrastructure projects can become geopolitical issues. A dam may be an engineering project on paper, but when it is built on a river crossing an international boundary, its design can acquire strategic significance.

India versus the arbitration panel: the key differences

The overlooked issue: who gets to decide?

One of the most important aspects of the current dispute is often lost beneath headlines about dams and rivers.

The real institutional question is who has the final authority to determine what the treaty means.

If India does not recognise the arbitration process, another ruling from the same body is unlikely to change New Delhi’s position. Conversely, Pakistan has an incentive to continue using the mechanisms it believes are legally available to challenge Indian projects.

This creates a potentially persistent cycle: Pakistan seeks legal adjudication, the tribunal issues a decision, India rejects the tribunal’s jurisdiction, and the underlying technical disagreement remains unresolved.

That cycle could become more important than any individual award.

Why the Ratle project is particularly important

The Ratle hydroelectric project has become one of the most prominent flashpoints in the Indus Waters Treaty dispute.

Its significance goes beyond electricity generation. It represents the broader disagreement over how India can use western-river waters while remaining within the treaty’s technical restrictions.

For India, hydropower development is closely connected to the economic and infrastructure needs of Jammu and Kashmir. For Pakistan, projects on rivers flowing into its territory raise concerns about downstream water security.

The disagreement therefore combines engineering, economics, international law and national security.

Why the World Bank’s role is frequently misunderstood

The World Bank was instrumental in facilitating the original Indus Waters Treaty, but its role should not be mistaken for that of a conventional international court or political mediator capable of simply forcing either country to accept every decision.

The treaty assigns specific procedural roles to different institutions, including the World Bank in certain circumstances.

The present controversy demonstrates why that distinction matters. The central disagreement is between India and Pakistan over the interpretation and operation of the treaty’s own dispute-resolution framework.

Could the treaty survive the current crisis?

The Indus Waters Treaty has demonstrated remarkable resilience. It survived wars, diplomatic crises and prolonged periods of hostility between India and Pakistan.

However, the present dispute is testing something different: whether the countries can continue to accept the institutional machinery that makes the treaty workable.

An international agreement can remain valuable only when its parties have enough confidence in its procedures to keep using them. Once the legitimacy of those procedures becomes contested, even technically solvable disagreements can become much harder to settle.

This is arguably the biggest long-term risk facing the treaty framework.

Real-world impact on water and energy security

The consequences of the dispute could extend well beyond diplomatic statements.

For India, greater development of Himalayan hydropower resources could support electricity generation and infrastructure growth. For Pakistan, predictable water flows remain essential to agriculture and irrigation.

Any prolonged uncertainty could therefore affect decisions involving dams, power generation, water storage and river management.

There is also a climate dimension. Changing rainfall patterns, glacier conditions and extreme weather events are making Himalayan water management increasingly complex. Future water disputes may involve not only treaty interpretation but also questions about how both countries adapt to a changing hydrological environment.

What happens next?

The immediate possibility of a simple legal resolution appears limited because the fundamental disagreement concerns jurisdiction itself.

India is unlikely to treat a ruling as binding when it does not recognise the tribunal that issued it. Pakistan, meanwhile, has strong reasons to continue defending the treaty framework and seeking international legal support for its interpretation.

The dispute could therefore continue through a combination of diplomatic statements, legal proceedings, technical disagreements and infrastructure decisions.

Ultimately, the most durable solution is likely to require some form of functioning communication between the two countries on water management, even if broader political relations remain hostile.

Prediction: the next phase may be more about infrastructure than courts

The most consequential developments may increasingly happen on the ground rather than inside courtrooms.

If India continues expanding or modifying hydroelectric infrastructure on the western rivers while rejecting the arbitration process, Pakistan may intensify diplomatic and legal efforts to challenge those developments.

At the same time, India’s emphasis on sovereignty and strategic water management suggests that future decisions about Himalayan infrastructure could be closely linked to its broader national-security policy.

That means the Indus Waters Treaty dispute could gradually become less about a single ruling and more about the future architecture of water management between two nuclear-armed neighbours.

Conclusion: a water treaty caught in a geopolitical storm

India’s rejection of the Hague-based Indus Waters Treaty ruling marks another escalation in a dispute that has moved far beyond technical questions about dams and river flows.

New Delhi’s position is clear: it does not recognise the Court of Arbitration as legally constituted and therefore rejects its authority over India. The tribunal, on the other hand, maintains that the Indus Waters Treaty remains in force and that its proceedings are valid under the agreement.

The result is a significant legal and diplomatic impasse.

The deeper challenge is whether India and Pakistan can preserve a workable system for managing shared rivers when their wider relationship is dominated by security tensions. The treaty survived decades of hostility because both sides continued to participate in its mechanisms.

The latest confrontation puts that foundation under greater pressure.

The future of the Indus Waters Treaty may therefore depend less on another courtroom ruling and more on whether the two countries can eventually restore enough trust — or at least practical cooperation — to manage water as a shared necessity rather than another front in their strategic rivalry.
