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 RiversWestern Rivers
Beas, Ravi, SutlejChenab, Indus, Jhelum
Allocated to IndiaAllocated largely to Pakistan
Exclusive, unrestricted useIndia 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:

  1. Permanent Indus Commission (PIC)
  • All minor "questions" addressed bilaterally
  • Regular meetings between both countries
  1. Neutral Expert
  • Unresolved technical "differences" referred here
  • Appointed by World Bank
  • Highly qualified engineer
  1. 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
