'Illegally constituted': MEA rejects Pakistan-backed Court of Arbitration ruling on Indus Waters Treaty

What Happened
- The Ministry of External Affairs rejected the latest award issued on 15 May 2026 by the Court of Arbitration convened under the Indus Waters Treaty (IWT), calling it "null and void."
- The MEA's official spokesperson reiterated that India has never recognised the court's constitution and has consistently held that it was "illegally constituted" under the treaty framework.
- India's position is that the correct mechanism for resolving the hydroelectric project disputes is the Neutral Expert process, not the Court of Arbitration, since the two processes cannot run in parallel.
- The IWT itself remains in abeyance since April 2025 — a posture India has maintained as a diplomatic response to cross-border terrorism — making all treaty-based dispute resolution mechanisms effectively suspended from India's standpoint.
- India has not participated in any of the Court of Arbitration's proceedings.

Indus Waters Treaty, 1960
The Indus Waters Treaty was signed on 19 September 1960 in Karachi between India and Pakistan, with the World Bank as a co-signatory and guarantor. It is one of the world's most enduring water-sharing agreements, having survived multiple wars between the two countries. Under the treaty, the three eastern rivers — Ravi, Beas, and Sutlej — were allocated to India, while the three western rivers — Indus, Jhelum, and Chenab — were allocated to Pakistan. India retains limited rights to non-consumptive use (hydroelectric projects, irrigation within specified limits) on the western rivers.
- Signed: 19 September 1960; Signatories: India, Pakistan, and the World Bank
- Eastern rivers (India's exclusive use): Ravi, Beas, Sutlej
- Western rivers (Pakistan's exclusive use with India's limited rights): Indus, Jhelum, Chenab
- Dispute resolution mechanism established under Article IX — a graded three-tier structure
- Permanent Indus Commission (PIC): a joint body with one commissioner per country, responsible for first-level resolution of implementation questions
Connection to this news: India's rejection of the arbitration award rests on Article IX's sequencing logic — the matter should first go to a Neutral Expert, not directly to arbitration. India argues Pakistan violated this procedure, rendering the court illegally constituted.
Article IX — Dispute Resolution Mechanism under IWT
Article IX of the IWT establishes a graded, multi-tier dispute resolution structure. "Questions" (routine implementation matters) go to the Permanent Indus Commission. "Differences" on technical matters specified in Annexure F go to a Neutral Expert — a highly qualified engineer appointed by mutual agreement or by the World Bank. "Disputes" of broader legal character, after exhausting earlier steps, may be referred to a seven-member Court of Arbitration constituted under Annexure G, administered by the Permanent Court of Arbitration (PCA) at The Hague.
- Tier 1 — Permanent Indus Commission: first examination of any question
- Tier 2 — Neutral Expert: technical "differences," especially on hydroelectric project design; decisions are final on technical matters
- Tier 3 — Court of Arbitration (Annexure G): broader "disputes"; seven-member tribunal under PCA auspices
- The two processes (Neutral Expert and Court of Arbitration) are mutually exclusive for the same subject matter under India's reading
Connection to this news: India initiated the Neutral Expert route for the Kishanganga and Ratle disputes; Pakistan simultaneously activated the Court of Arbitration. India views the parallel activation as treaty-inconsistent and has refused to participate in arbitration proceedings, calling the court's constitution illegal.
Kishanganga and Ratle Hydroelectric Projects
The immediate technical dispute concerns two hydroelectric power plants being developed by India on tributaries of Pakistan's western rivers. The Kishanganga project (330 MW) is on the Kishanganga river, a tributary of the Jhelum. The Ratle project (850 MW) is on the Chenab river. Pakistan contends that design features of both projects violate IWT provisions governing pondage, drawdown, and minimum flow obligations on the western rivers.
- Kishanganga HEP: 330 MW, on Kishanganga (tributary of Jhelum, a western river)
- Ratle HEP: 850 MW, on Chenab (a western river)
- Pakistan's objections: design parameters allegedly contravene IWT Annexures
- Both projects are located in Jammu and Kashmir
- A 2009 Kishanganga arbitration award allowed India to divert waters subject to conditions
Connection to this news: The 15 May 2026 Court of Arbitration award relates directly to these two projects. India's non-participation and treaty-abeyance posture means it does not consider itself bound by any such award.
Treaty in Abeyance — India's Post-Pahalgam Position
Following the Pahalgam terror attack of 22 April 2025, which killed 26 people, India's Cabinet Committee on Security decided to place the IWT in abeyance with immediate effect. India's stated condition for restoration is that Pakistan credibly and irreversibly ends support for cross-border terrorism. This is the first time since 1960 that any party has formally suspended the treaty's operation.
- Pahalgam attack: 22 April 2025, 26 killed; attributed to an outfit linked to Lashkar-e-Taiba
- India's condition for reversal: cessation of cross-border terrorism support by Pakistan
- Pakistan's stance: treaty remains "fully operational and effective" from its side
- Effect on dispute resolution: with the treaty in abeyance, India treats all IWT mechanisms as suspended
Connection to this news: The MEA's rejection of the 15 May 2026 arbitration award reaffirms the abeyance posture — India does not recognise the court's awards regardless of their content, because the treaty framework itself is suspended from India's perspective.
