India rejects Permanent Court of Arbitration (CoA) ruling on Indus Waters Treaty (IWT)

India rejects Permanent Court of Arbitration (CoA) ruling on Indus Waters Treaty (IWT)

India has reiterated that it does not recognize the authority of the Court of Arbitration (CoA) constituted under the Indus Waters Treaty and has also kept the treaty in abeyance amid continuing disputes with Pakistan over hydroelectric projects on western rivers.

Indus Water Treaty (IWT)

Indus Water Treaty has recently come into focus after India refused to recognize the Court of Arbitration (CoA) constituted regarding disputes over the Kishenganga and Ratle hydroelectric projects.

India has also kept the treaty in abeyance amid continuing tensions with Pakistan.

Background of the Dispute

Court of Arbitration (CoA)

The Court of Arbitration:

  • Is a five-member arbitral panel

  • Constituted in 2023 at Pakistan’s request

Pakistan challenged:

  • Design features of Kishenganga Hydroelectric Project

  • Ratle Hydroelectric Project

India’s Position

India refused participation because:

  • The dispute, according to India, falls within the jurisdiction of a Neutral Expert

  • Not under a Court of Arbitration

India argues:

  • Parallel proceedings violate treaty provisions

“Water cooperation is often the first casualty during geopolitical tensions.”

Challenges Facing IWT

1. Geopolitical Tensions

Political hostility affects cooperation.

2. Climate Change

Changing river flows due to:

  • Erratic rainfall

3. Increasing Water Demand

Growing population and agriculture pressures.

4. Technological and Infrastructure Disputes

Frequent disagreements over:

  • Hydropower projects

  • Engineering designs

India’s Concerns

India argues:

  • Treaty provisions are outdated

  • Pakistan frequently obstructs legitimate hydropower projects

India also seeks:

Conclusion

The Indus Water Treaty remains a landmark example of international river-water cooperation despite decades of geopolitical rivalry between India and Pakistan. However, evolving strategic tensions, climate pressures, and disagreements over hydropower projects such as Kishenganga and Ratle have increasingly tested the treaty’s institutional mechanisms and long-term sustainability.
