Introduction
The Indus Waters Treaty (IWT), signed in 1960 between India and Pakistan, remains one of the world’s most successful examples of international water-sharing agreements. Despite decades of hostilities between the two nations, the IWT has largely survived, showcasing the resilience of international treaty law. This article examines the Treaty’s origin, the individuals and organizations involved in its formulation, the international legal framework underpinning it, its dispute resolution mechanisms, and the legal consequences of a potential violation.
Can a Party Suspend the treaty on its own?
Under the Indus Waters Treaty (IWT), a party cannot unilaterally suspend or terminate the agreement. Article XII of the IWT clearly states that the Treaty shall remain in force unless both India and Pakistan mutually agree to terminate or modify it through a duly ratified treaty. Therefore, any unilateral suspension would be a violation of the Treaty’s terms. Even under international law, specifically the Vienna Convention on the Law of Treaties, suspension or termination requires specific conditions and a formal process, making unilateral action legally untenable.
The IWT cannot be terminated unilaterally.
It only ends if India and Pakistan both sign a new treaty — meaning mutual consent is necessary. No party can just declare “we are suspending” and walk away. This the significance of Article 12
Legal Significance of Article XII
- Permanency: Establishes that the Treaty is not time-bound or conditional; it’s intended to govern river use indefinitely.
- Mutual Consent Principle: Ensures that neither party can change or exit the Treaty unilaterally — reinforcing the doctrine of pacta sunt servanda (agreements must be kept).
- Neutral Role of the World Bank: Limits the World Bank’s involvement to a procedural and facilitative role after initial financial responsibilities.
Practical Effect
- Even during wars (1965, 1971, Kargil conflict 1999), the Treaty remained operational.
- Calls from any side to “unilaterally abrogate” the Treaty have no legal basis under international law without mutual consent.
- Any attempt to suspend or terminate it without bilateral agreement would violate Article XII and expose the violator to international legal consequences.
Origin of the Indus Waters Treaty
Following the partition of British India in 1947, the newly formed dominions of India and Pakistan inherited a common irrigation system fed by the Indus River and its tributaries. Initial interim arrangements proved inadequate, and tensions heightened when India temporarily suspended water supplies to Pakistan on April 1, 1948, leading to the Inter-Dominion Agreement.
Recognizing the need for a permanent solution, David E. Lilienthal, former head of the Tennessee Valley Authority and the U.S. Atomic Energy Commission, proposed in 1951 that both countries cooperatively develop the Indus system. His proposal caught the attention of Eugene R. Black, then President of the World Bank, who took the initiative to mediate between India and Pakistan.
After nearly a decade of complex negotiations involving engineers, diplomats, and international legal experts, the Treaty was formally signed on September 19, 1960, by:
- Jawaharlal Nehru, Prime Minister of India
- Field Marshal Mohammad Ayub Khan, President of Pakistan
- W.A.B. Iliff, representing the World Bank
The Treaty was signed in Karachi, Pakistan.
Provisions of the Treaty:
The Indus Waters Treaty (IWT), signed between India and Pakistan with the World Bank as a third-party guarantor, is divided into a Preamble and twelve Articles, followed by eight Annexures and four Schedules.
It meticulously outlines the rights and obligations of the two parties regarding the use of the Indus system of rivers.
Division of Rivers (Article II and III)
- The Eastern Rivers — Ravi, Beas, and Sutlej — are allocated to India for exclusive use.
- The Western Rivers — Indus, Jhelum, and Chenab — are allocated to Pakistan for exclusive use, with limited rights of use granted to India. India’s limited rights on the Western Rivers include:
- Non-consumptive uses (e.g., hydroelectric generation without storage).
- Certain types of agricultural use within specified areas.
- Domestic use (drinking, sanitation).
- Run-of-the-river hydroelectric projects, under strict design and operational conditions.
Dispute Resolution Mechanism (Article IX)
Three stages:
- Permanent Indus Commission (PIC): First line of settlement for differences.
- Neutral Expert: For technical differences (e.g., design issues).
- Court of Arbitration: For disputes relating to Treaty interpretation or serious disagreements.
The World Bank plays a role in facilitating the appointment of a Neutral Expert or constituting a Court of Arbitration when necessary.
Article XII — Final Provisions
1. Binding Nature
- The Treaty binds both India and Pakistan in perpetuity.
- This means that the Treaty remains effective and operative regardless of political changes, wars, or other external developments.
- Neither party can unilaterally withdraw from or terminate the Treaty.
2. Amendment and Modification
- The Treaty can only be modified or terminated by mutual agreement between India and Pakistan.
- Any such modification or termination must be recorded in a formal treaty, ratified by both governments.
3. World Bank’s Role
- While the World Bank was initially a party to certain obligations (mainly financial and procedural), after the completion of specific tasks (especially financial arrangements), the World Bank’s obligations were considered discharged.
- The World Bank no longer has any ongoing operational responsibility unless specifically re-engaged for dispute resolution (Neutral Expert appointment, etc.).
People and Organizations Involved
The key entities instrumental in the negotiation and conclusion of the IWT were:
- Government of India and Government of Pakistan
- The World Bank (then International Bank for Reconstruction and Development) — acted as a mediator and later became a guarantor
- Technical experts and hydrologists from both countries
- International legal advisors who ensured that the Treaty aligned with emerging principles of international water law
The World Bank also helped arrange funding for building new canals, storage works, and hydropower projects essential for implementing the Treaty’s provisions.
International Legal Framework Supporting the Treaty
Though primarily a bilateral treaty, the IWT rests on several principles now codified or recognized in international law:
- Customary International Law on Shared Watercourses
- Even before the UN Convention on the Law of the Non-Navigational Uses of International Watercourses (1997), customary international law emphasized equitable and reasonable utilization and obligation not to cause significant harm to co-riparians.
- UN Watercourses Convention (1997)(Reflective, though neither India nor Pakistan is a party)
- Codifies principles like sustainable use, prior notification of planned measures, and dispute resolution.
- Berlin Rules on Water Resources (2004)
- Reaffirm the obligation to avoid transboundary harm, promote equitable utilization, and foster cooperation between riparian states.
The Treaty itself embodies many of these norms, making it consistent with broader international practices even decades after its signing.
Dispute Resolution Mechanism Under the Treaty
The IWT provides a multi-tiered dispute resolution system:
- Permanent Indus Commission
- Composed of one commissioner from each country. Regular meetings are held to resolve routine issues.
- Neutral Expert
- If the Commission fails to resolve a technical difference, either party may request the World Bank to appoint a neutral expert.
- Court of Arbitration
- For disputes involving legal interpretations or more serious issues, the Treaty allows for setting up an international Court of Arbitration.
- The Court is constituted with the assistance of the World Bank, ensuring neutrality.
This layered approach has helped prevent escalation of water disputes over the decades.
Consequences of Violation
A unilateral violation by India, such as stopping or diverting the western rivers’ flow, would have the following consequences:
- Breach of Treaty Obligations
- Would constitute a material breach of a binding international agreement under Articles 26 and 60 of the Vienna Convention on the Law of Treaties (1969) (pacta sunt servanda — treaties must be performed in good faith).
- Liability under International Law
- Could violate customary norms such as the duty to prevent significant harm to co-riparian states.
- Dispute Escalation
- Pakistan could invoke the Treaty’s dispute mechanisms, possibly moving to the appointment of a Neutral Expert or even a Court of Arbitration.
- Pakistan could also approach international forums like the International Court of Justice (ICJ), though jurisdictional hurdles exist.
- Geopolitical and Strategic Fallout
- Damage to India’s international reputation as a responsible treaty partner.
- Strain relations with global stakeholders and regional actors like China.
- Increase instability in South Asia, potentially impacting security and trade.
- Potential Retaliation
- Pakistan could retaliate diplomatically or otherwise, possibly affecting broader bilateral relations beyond water issues.
Conclusion
The Indus Waters Treaty remains a vital symbol of cooperation amidst enmity. Its resilience owes much to the strong legal framework, practical dispute mechanisms, and international support behind it. While geopolitical tensions may provoke calls to revise or abandon the Treaty, any breach would have serious legal, diplomatic, and security consequences. Careful adherence to treaty obligations, along with lawful exploration of available rights, remains the most prudent course for both India and Pakistan.
Some interesting points:
- Even during the wars between India and Pakistan (1965, 1971, Kargil 1999), the Treaty held strong.
- There have been tensions recently, especially after attacks like Uri (2016) and Pulwama (2019), when some Indian politicians talked about revisiting or scrapping the Treaty.
- Disputes under the Treaty are supposed to be resolved through a graded process: first negotiation, then a neutral expert, and finally a court of arbitration if necessary.
- Recently, India has taken steps to speed up projects like Kishanganga and Ratle hydroelectric projects in Jammu and Kashmir, which Pakistan has objected to.
The Treaty is often called one of the most successful water-sharing agreements in the world, despite the bitter relationship between India and Pakistan.
