Pakistan, India and the Indus Waters Treaty: Compliance, Silence and Accountability

India’s continued non-compliance with PCA directives under IWT exposes a pattern of ignoring international law while Pakistan upholds treaty obligations.

The Indus Waters Treaty (IWT) remains one of the most significant bilateral water-sharing agreements, underpinning the livelihoods of nearly 240 million Pakistanis. Yet, India’s repeated non-compliance with treaty obligations has placed this vital framework under stress. On 29 January 2026, the Permanent Court of Arbitration (PCA) issued Procedural Order No. 19, confirming its jurisdiction and directing India to provide operational data for the Baglihar and Kishanganga hydroelectric projects. The deadline for compliance was set as 9 February 2026. India’s failure to respond or provide the required information is not merely procedural non-cooperation, it represents a clear breach of international obligations and established accountability mechanisms.

India’s Silence and Breach of Treaty Obligations

Silence in this context carries weight. The PCA specifically requested data on reservoirs, logbooks, and operational analyses, information exclusively under India’s control and essential for verifying compliance with the treaty. By withholding these critical materials, India not only violates procedural requirements but also undermines the evidentiary process established to ensure transparency and fairness. Meanwhile, Pakistan continues to provide all necessary documentation, demonstrating both compliance and institutional transparency.

The PCA has made it clear that arbitration continues irrespective of India’s participation. Under international law, particularly the principle of pacta sunt servanda, treaty obligations cannot be suspended unilaterally. India’s non-cooperation, therefore, carries negative legal implications, weakening any technical or legal claims it may assert. Furthermore, the court’s reliance on Pakistan to present evidence reinforces Pakistan’s position as a compliance-oriented treaty partner. India’s refusal to engage or provide operational data strengthens Pakistan’s case in arbitration and diminishes India’s credibility in both legal and diplomatic spheres.

Patterns of Accountability and International Implications

India’s pattern of silence is not limited to PCA directives. United Nations Special Rapporteurs raised questions in October 2025, with a response deadline of 16 December 2025. Even 55 days later, India had not replied, reflecting a sustained pattern of disregarding international accountability mechanisms. Such repeated inaction signals a political posture rather than any technical or legal justification. By contrast, Pakistan has consistently maintained transparency, institutional participation, and adherence to treaty mechanisms, emphasizing that compliance and accountability are non-negotiable elements of international law.

The stakes of this ongoing non-compliance extend far beyond procedural disputes. Any disruption to water-sharing arrangements affects agriculture, energy production, and millions of lives in Pakistan. It is therefore a matter not just of bilateral diplomacy but of international concern. Pakistan’s sustained efforts to document compliance and participate fully in PCA proceedings demonstrate its commitment to the rule of law and institutional accountability. India’s continued absence, however, invites legal consequences, reputational damage, and increased scrutiny in multilateral forums.

Ultimately, this episode underscores a fundamental principle: treaty obligations, once agreed upon, cannot be unilaterally ignored without consequences. Pakistan’s approach reinforces the integrity of the Indus Waters Treaty, highlights India’s non-compliance, and sends a clear message to the international community that transparency, legal adherence, and institutional participation are paramount. Silence, while politically expedient, does not suspend responsibility; it only strengthens the legal and moral case of the party committed to compliance.
