India Rejects Indus Waters Treaty Arbitration Ruling, Says Agreement Remains in Abeyance

India has rejected the latest ruling concerning the Indus Waters Treaty, maintaining that its decision to keep the decades-old water-sharing agreement with Pakistan in abeyance continues to remain valid. New Delhi has also challenged the authority of the arbitration body that issued the ruling, arguing that the tribunal itself was created in violation of the treaty framework.

The Ministry of External Affairs (MEA) issued the response on Monday after the arbitration panel maintained that India’s reasons for putting the treaty on hold did not provide grounds for suspending or ending its obligations under the agreement. The panel called for the treaty to continue operating and for India to comply with its provisions.

India Questions Tribunal’s Legitimacy

New Delhi’s central objection is not limited to the substance of the ruling. India has consistently disputed the legal status of the Court of Arbitration constituted in connection with the Indus Waters Treaty.

According to the MEA, India does not recognise the tribunal as a legally valid body and has never participated in its proceedings. The government argues that the establishment of the arbitration mechanism itself breached provisions of the treaty.

The ministry reiterated that India therefore does not accept the latest pronouncement or earlier decisions issued by the body. It also maintained that the tribunal has no authority to determine matters that India considers part of its sovereign decision-making.

The government further stated that decisions issued by the arbitration body, whether already delivered or issued in the future, will not determine how India proceeds with projects connected to its water resources.

Treaty Put on Hold After Pahalgam Attack

The latest confrontation is rooted in India’s decision in April 2025 to place the Indus Waters Treaty in abeyance following the deadly terror attack in Pahalgam.

The April 22, 2025 attack claimed 26 lives and significantly worsened already strained relations between India and Pakistan. In its aftermath, India announced that the water-sharing arrangement would be kept in abeyance.

The decision represented a major shift in the handling of an agreement that had governed the distribution of waters from the Indus river system between the two countries for decades.

The arbitration panel, however, has taken a different position, arguing that India’s stated justification did not provide a basis for suspending or terminating its treaty obligations. It has consequently maintained that the agreement remains operative and that India should continue to follow its provisions.

Long-Running Dispute Over Water Rights

The Indus Waters Treaty was signed in 1960 and established a framework for managing the waters of the Indus river system shared by India and Pakistan. The agreement has historically remained in place despite several wars, diplomatic crises and periods of severe tension between the two neighbours.

Under the arrangement, the eastern rivers — Ravi, Beas and Sutlej — were allocated primarily for India's use, while the western rivers — Indus, Jhelum and Chenab — were largely reserved for Pakistan, subject to specific rights and conditions provided under the treaty.

The agreement also created mechanisms for resolving disagreements between the two countries. Those mechanisms have increasingly become a point of contention, particularly as India and Pakistan have disagreed over the interpretation of provisions governing hydroelectric projects.

Impact on India’s Projects

India’s latest statement makes clear that New Delhi does not intend to treat the arbitration ruling as a restriction on its sovereign decisions relating to water and infrastructure projects.

The MEA has specifically argued that the arbitration body lacks jurisdiction over such decisions. As a result, India has indicated that the ruling will not alter its approach toward projects currently being undertaken.

The dispute is particularly significant for hydroelectric development in Jammu and Kashmir, where India has been pursuing projects on rivers covered by the treaty. International arbitration proceedings have previously examined technical questions concerning the design and operation of Indian hydroelectric facilities.

A recent ruling also addressed construction at the Ratle hydroelectric project, directing India to restrict certain work while a neutral expert considers whether aspects of the project comply with treaty requirements.

Another Diplomatic Flashpoint

The latest exchange adds another layer to the increasingly complicated India-Pakistan dispute over water resources.

For Pakistan, the Indus river system is critical to agriculture, energy generation and broader water security. For India, the issue is closely linked to national security, sovereignty and its ability to develop infrastructure in Jammu and Kashmir.

India’s rejection of the arbitration ruling therefore leaves the two sides with sharply different positions. The arbitration body maintains that the treaty continues to operate, while New Delhi insists that its decision to keep the agreement in abeyance remains firmly in place.

The immediate dispute may consequently continue through diplomatic and legal channels, with the competing interpretations of the treaty adding to broader tensions between the two countries.

For now, India’s position is unequivocal: it does not recognise the authority of the arbitration body and says the decision to keep the Indus Waters Treaty in abeyance remains in force.
