Pakistan Secures Landmark Indus Waters Ruling at The Hague as India Dismisses Verdict

A court of arbitration in The Hague has ruled that India cannot unilaterally suspend the Indus Waters Treaty, rejecting every argument New Delhi has used to justify holding the six-decade-old water-sharing agreement “in abeyance” since April 2025.

In a unanimous decision issued on Monday, the five-member court found that the treaty “remains fully in force” and that India “must observe its obligations” under it, including those governing the design and operation of hydropower projects on rivers that flow into Pakistan. The ruling marks the first time an international court has addressed whether India’s decision to place the treaty in abeyance is legally valid.

India announced the decision in April 2025 following a deadly attack on tourists in Indian-administered Kashmir, stating it would suspend the treaty until Pakistan “credibly and irrevocably” ends support for cross-border terrorism. Islamabad has consistently denied accusations of involvement in the attack, which claimed the lives of 26 civilians.

India rejected the jurisdiction of the Permanent Court of Arbitration (PCA) in this case and did not participate in any of the hearings. Promptly rejecting the verdict, India left Pakistan with a legal and diplomatic victory whose practical impact remains to be tested.

After India placed the pact in abeyance in April 2025, Pakistan applied in March 2026 for the PCA to rule on its status. Hearings proceeded at the Peace Palace in The Hague from April 26 to 28, 2026, with only Pakistan in attendance after India did not respond to the court's invitation.

The court examined all grounds cited publicly by India—sovereignty, alleged unwillingness to renegotiate, cross-border terrorism, and changes such as demographic growth, clean-energy needs, and climate change—and rejected every single one, concluding that no rule of international law allows a state to unilaterally suspend a treaty.

Pakistan’s Deputy Prime Minister and Foreign Minister Ishaq Dar welcomed the unanimous award in a statement on X, urging India to fully comply with its obligations. Meanwhile, India’s Ministry of External Affairs issued a statement calling the court “illegally constituted” and maintaining that the abeyance remains in force.

Legal experts note that while the ruling strengthens Pakistan's legal stance, it lacks a direct enforcement mechanism. Ahmer Bilal Soofi and Sikander Ahmed Shah both emphasized that the judgment provides a clear legal basis for countermeasures or diplomatic pressure, even without a formal enforcement tool comparable to a UN Security Council order.

Pakistani officials have outlined steps for compliance, calling for the resumption of the Permanent Commission, routine data sharing, and site inspections. However, the dispute has increasingly taken on existential undertones among Pakistani leadership, with figures like Musadik Malik, Bilawal Bhutto Zardari, and Prime Minister Shehbaz Sharif warning of severe security implications regarding water access.

Conversely, hydrology and water resources expert Hassan Abbas suggested that immediate threats to Pakistan's water supply are limited, noting that western rivers are largely protected by geography and that India's run-of-river facilities offer minimal storage capacity.
