Key Facts and Data Points
The Court of Arbitration's Ruling
- The CoA ruled that India's decision to place the IWT in "abeyance" following the April 2025 Pahalgam terror attack was not permissible under the treaty or international law
- Terrorism not grounds for suspension: Cross-border terrorism does not constitute a "material breach" of the water pact
- Interim restrictions imposed on Ratle project construction activities until 90 days after Neutral Expert's final decision (expected 2027)
- The Court stated the treaty governs only water rights and does not address terrorism or use of force
India's Stand
- Parallel proceedings violation: Pakistan sought CoA while India requested Neutral Expert examination
- India argues simultaneous proceedings violate the IWT's sequential dispute-resolution mechanism
- World Bank's role: Paused both processes in 2016 but allowed simultaneous proceedings in 2022
- India joined Neutral Expert process but boycotted CoA proceedings
- Maintains CoA has no jurisdiction over India's abeyance decision
Background and Context
About the Indus Waters Treaty (1960)
- Brokered by: World Bank
- Signed: September 19, 1960, in Karachi
- One of the most successful water-sharing agreements globally, surviving multiple wars between India and Pakistan
River Allocation under IWT
| Eastern Rivers | Western Rivers |
|---|---|
| Beas, Ravi, Sutlej | Chenab, Indus, Jhelum |
| Allocated to India | Allocated largely to Pakistan |
| Exclusive, unrestricted use | India permitted limited non-consumptive uses |
India's Rights on Western Rivers
- Domestic use
- Agriculture
- Run-of-the-river hydroelectric power generation
- Must adhere to strict technical parameters outlined in the treaty
Dispute Resolution Mechanism under IWT
The treaty follows a graded mechanism:
- Permanent Indus Commission (PIC)
- All minor "questions" addressed bilaterally
- Regular meetings between both countries
- Neutral Expert
- Unresolved technical "differences" referred here
- Appointed by World Bank
- Highly qualified engineer
- Court of Arbitration (CoA)
- Formal "dispute" resolution
- If Neutral Expert finds issue is legal rather than technical
- Or if both parties agree
- Highest dispute-resolution mechanism under the treaty
Core Dispute: Hydroelectric Projects
Kishenganga Project
- Capacity: 330 MW
- Location: Kishenganga River (tributary of Jhelum), Jammu & Kashmir
- Type: Run-of-the-river project
Ratle Project
- Capacity: 850 MW
- Location: Chenab River, Jammu & Kashmir
- Type: Hydroelectric project
Pakistan's Objection
- Claims India is building pondage (water storage) capacities far larger than technically required
- Allegedly impacts water flow to Pakistan
- Consequently requested CoA (legal dispute)
- India requested Neutral Expert (technical assessment)
About the Court of Arbitration
- Ad-hoc five-member tribunal established under Annexure G of IWT, 1960
- Highest dispute-resolution mechanism for legal disputes
- Permanent Court of Arbitration (PCA) in The Hague serves as Secretariat
- Present CoA constituted by World Bank at Pakistan's request in 2022-23
Significance for India
Sovereignty Dimension
- India's decision to place IWT in abeyance is a sovereign matter
- Rejection of CoA jurisdiction reaffirms India's position on territorial integrity and national security
Legal Framework
- Challenges the sequential dispute-resolution mechanism
- Questions World Bank's role in allowing parallel proceedings
Strategic Implications
- Treaty's survival since 1960 demonstrates resilience of international agreements
- However, terrorism as a grounds for suspension remains contested
Constitutional and Legal Provisions
- Article 253: Deals with implementation of treaties; doesn't directly apply here but establishes Parliament's role
- International law principle: Rebus sic stantibus (fundamental change of circumstances) - India's argument for abeyance
- World Bank's role: As broker and facilitator of dispute resolution mechanisms
