Reporting snapshot · 31 August 2026. This reports the Permanent Court of Arbitration's award and interim measures as described by Pakistan's state news agency, together with India's rejection of the tribunal. The dispute remains contested, and the measures summarised here are provisional.
What happened
The Permanent Court of Arbitration (PCA) at The Hague ruled on Monday, 31 August 2026, that the Indus Waters Treaty of 1960 remains fully in force and that India cannot unilaterally suspend it, Pakistan’s state news agency APP reported. The tribunal issued an Award on Treaty Status together with a binding Order on Interim Measures.
The court found that India’s declaration placing the treaty “in abeyance” carried no technical or legal weight, and that none of the grounds India advanced — claims of sovereignty, allegations of cross-border terrorism or a fundamental change in circumstances — justified suspension or termination. It reaffirmed the principle that agreements must be kept, known in international law as pacta sunt servanda.
What the court ordered
Alongside the award, the PCA issued interim measures restraining Indian construction at the Ratle Hydro-Electric Plant (RHEP). The court barred India from concreting the plant’s dam wall and power intake structure above specified levels, and ordered India to submit regular reporting on its construction schedules.
The prohibition is to remain in force until 90 days after a Neutral Expert delivers a final determination on whether the plant’s design complies with the treaty. APP reported that the court’s ruling rejected India’s argument that “abeyance” was a valid legal device, and that it re-established that India must respect Pakistan’s rights over the Western Rivers within the treaty’s mechanisms.
Background
India placed the Indus Waters Treaty in abeyance after an attack in Indian Illegally Occupied Jammu and Kashmir in April 2025, saying the suspension would last until Pakistan met political conditions. The treaty, brokered by the World Bank in 1960, divides the waters of six rivers between the two countries and has no exit clause. The dispute over the Ratle plant and other Indian projects has run alongside the wider suspension. Pakistan has said the treaty was also discussed in the lead-up to the ruling, as in Ishaq Dar’s 28 August warning that suspending the treaty would be treated as an act of war.
Responses
Deputy Prime Minister and Foreign Minister Ishaq Dar welcomed the award. In a post on X he said the decision “vindicates Pakistan’s consistent position that a binding international treaty cannot be unilaterally suspended or set aside,” and urged India to comply with its obligations under the treaty.
India rejected the ruling within hours. The Ministry of External Affairs said India had “never recognised the existence in law of this illegally-constituted and so-called Court of Arbitration,” described the body’s establishment as a grave violation of the treaty, and said its decision to hold the treaty in abeyance remained in force. India had not appeared before the tribunal.
Why it matters
The award is a legal and diplomatic result for Pakistan, which has argued that the 1960 treaty cannot be set aside through a unilateral declaration. But the effect on the ground is uncertain: India disputes the tribunal’s authority and has said the outcome will not change its actions on the projects it is building on the western rivers. The interim measures tie the Ratle dispute to the Neutral Expert’s timetable, with a final design determination expected later.
