India must uphold a water-sharing treaty with Pakistan it suspended amid bilateral tensions ​and must limit work on an hydroelectric plant it is building in the ‌Kashmir region, the Permanent Court of Arbitration in the Hague said on Monday.
India in April last year suspended the treaty that ensures water supply to 80% of Pakistani farms, after India identified as ​Pakistani two of three assailants in an attack that killed 26 people at ​a tourist destination in Kashmir that month.
Islamabad denied any role in the ⁠attack and took legal action after India last year also began work to boost reservoir ​holding capacity at two hydroelectric projects in the Kashmir region.

This was seen as a first ​tangible step by India to operate outside agreements covered by the Indus Waters Treaty between the two countries, which both have honored since 1960 despite three wars and several other conflicts between them.
The Permanent ​Court of Arbitration said the Indus Water Treaty remained fully in force, as India had ​no justification for ending or suspending the agreement.”India must observe its obligations under the Treaty, including those ‌relating ⁠to the design and operation of its hydro-electric projects on the Western Rivers,” the intergovernmental court said.

India, which is officially a member of the court, said it did not recognize the court and “categorically” rejected the verdict.
“This so-called Court of Arbitration has no jurisdiction whatsoever ​to pronounce on India’s ​sovereign decisions,” India’s Ministry ⁠of Foreign Affairs said in a statement.”Its pronouncements, now or in the future, will have no effect on India’s actions in connection ​with the projects being undertaken by India.”The court said a neutral ​expert, appointed ⁠by the World Bank, would judge by July 2027 whether the construction of hydroelectric plants in the Himalayan region was in line with the treaty.
Agreeing with a demand by Pakistan, the ⁠court ​said India was not allowed to build the dam ​wall and power intake structure at the Ratle Hydro-Electric Plant above certain levels until 90 days after the neutral ​expert’s decision.
