Background
India and Pakistan signed the Indus Waters Treaty in 1960 with the World Bank. The treaty gives the eastern rivers Ravi, Beas and Sutlej to India. The Western Rivers, Indus, Jhelum and Chenab, go to Pakistan. India may build hydro projects on the Western Rivers under the treaty's design rules. Pakistan objects to the design of India's Kishenganga and Ratle projects. India asked the World Bank for a Neutral Expert. Pakistan asked for a Court of Arbitration. The World Bank appointed both in October 2022. India joined the Neutral Expert process. India says the treaty allows no parallel processes.

India rejects the award and says the Court has no legal standing
On 31 August 2026 India's Ministry of External Affairs rejected the award. The ministry called the Court an "illegally constituted so-called Court of Arbitration". The ministry said the World Bank set up the Court "in patent breach of the terms of the Treaty". The ministry said India has never appeared before the Court. The ministry said the Court's pronouncements "will have no effect on India's actions" on India's projects. The ministry said India's decision to hold the treaty in abeyance remains in force.
Why it matters for UPSC
The story is GS Paper 2: international treaties and dispute settlement. The Court says the treaty binds India, with no formal mechanism to enforce the award. Remember also: the word abeyance appears nowhere in the treaty text.
