INDIA’S unilateral suspension of the Indus Waters Treaty (IWT) violates international legal principles, as affirmed by the Permanent Court of Arbitration, which ruled that the IWT cannot be unilaterally annulled. The UNSC should invoke its mandate under Chapter VI of the UN Charter to facilitate peaceful resolution through mediation, given the treaty’s critical role in regional stability and water security. While the Hague-based Court of Permanent Arbitration’s ruling supports Pakistan’s position, sustained diplomatic engagement is essential to prevent escalation and ensure equitable water distribution in a climate-vulnerable region. Substantially, this article argues that UNSC intervention in the South Asian water dispute, under international law is inherently justifiable, as this issue is profoundly linked with the peace and security issues of the region.
Pakistan legal recourse: Pakistan’s leadership, including Foreign Minister Ishaq Dar, has written to the UNSC to draw attention to the humanitarian and security implications of India’s decision, demanding compliance with international obligations. Pakistan has rightly sought UN Security Council (UNSC) intervention to address India’s unilateral suspension of the Indus Waters Treaty (IWT). The Permanent Court of Arbitration (PCA) in The Hague has issued binding rulings—including its final award—affirming that the 1960 treaty remains fully valid. The court declared that India cannot unilaterally suspend, terminate, or sideline the IWT and must permit the waters of the western rivers (Indus, Jhelum, Chenab) to flow. It goes without saying that The UN Security Council (UNSC) can technically take notice of India’s unilateral suspension of the Indus Waters Treaty (IWT), as it involves a dispute between two sovereign states with regional security implications. Pakistan has formally lodged a complaint.
India maintains that the IWT remains valid and that its actions were in response to security threats, asserting its right to protect national interests. The fact remains that The UNSC could justifiably refer the South Asian water dispute to an international water commission. While the PCA’s decisions are binding under the Indus Waters Treaty, India’s unilateral actions weaken the treaty’s credibility. India’s claim that it does not accept the jurisdiction of the Permanent Court of Arbitration (PCA) in the Indus Waters Treaty (IWT) dispute lacks legal foundation. Once proceedings begin, a party’s unilateral objection cannot override the PCA’s established competence, as affirmed by the court. The IWT explicitly provides for arbitration in case of disputes, and India’s participation in the process—despite reservations—implies acceptance of the PCA’s role. Legal precedent supports that jurisdiction is determined by treaty terms, not post-initiation disavowal. Thus, India’s stance undermines the treaty’s framework and international legal principles.
India’s hawkish hydropolitics: India’s increasingly assertive hydropolitics, particularly regarding the Indus Waters Treaty (IWT), reflect a strategic shift toward maximizing control over Transboundary Riverslike Jhelum and Chenab. By advancing hydroelectric projects and exploiting legal ambiguities in the IWT, India undermines Pakistan’s water security, escalating regional tensions. This ‘ultra vires’ approach—exceeding treaty constraints—threatens long-term stability in South Asia, where water scarcity is intensifying. India’s dominance over headwaters of the Indus and Ganges systems amplifies geopolitical friction, raising concerns about environmental sustainability and diplomatic cooperation.
The Permanent Court of Arbitration (PCA) in The Hague has continuously ruled in favor of Pakistan’s legal position, recently affirming that the Indus Waters Treaty is legally binding and cannot be unilaterally held in abeyance or suspended by India. India has entirely rejected these PCA rulings, boycotting the court’s proceedings and arguing that the court lacks jurisdiction over the treaty.
Legal precedence: ‘’International law principles assert that states cannot arbitrarily withdraw from valid water-sharing treaties. However, enforcing PCA awards and compelling Indian participation in The Hague remains exceptionally difficult without an international enforcement mechanism’’. The move follows heightened tensions after a deadly incident in Indian-administered Kashmir, which India blamed on Pakistan. Islamabad, however, has denied involvement and warned that any attempt to block river flow would violate international law and could be seen as an act of war. The UN Security Council (UNSC) has the authority to take up international disputes that threaten peace.
Justification for UNSC intervention: While the UN Security Council (UNSC) is principally the highest forum for resolving international legal disputes between states, its effectiveness in the India-Pakistan water conflict—specifically regarding the Indus Waters Treaty (IWT)—is inherently not limited. Undeniably, The UN Security Council (UNSC) has the explicit legal mandate under Chapter VII of the UN Charter to intervene in any dispute that escalates into a threat to international peace and security, regardless of existing bilateral treaties. While the Indus Waters Treaty (IWT) provides a technical framework, a military or security escalation over water places the matter squarely within the UNSC’s jurisdiction.
That said, if the water dispute triggers an imminent threat of war, the UNSC can deploy several diplomatic and enforcement tools: Article 34, Chapter VII (Investigation): The UNSC can investigate the dispute to determine if its continuation is likely to endanger international peace. Article 36 (Recommendations): The Council can recommend specific procedures or methods of adjustment, even if they bypass the World Bank or the Permanent Indus Commission .Chapter VII Enforcement: If actual hostilities break out, the UNSC can issue binding resolutions, impose economic sanctions, or authorize military intervention to restore peace.
Conclusion: Pakistan’s concerns over India’s unilateral actions affecting the Indus Waters Treaty—such as suspending its implementation—raise legitimate security and peace issues, given water’s strategic importance. The treaty, brokered by the World Bank in 1960, remains a critical framework for regional stability. Should India’s actions threaten equitable water access, Pakistan may invoke international law to seek UNSC intervention, particularly if such actions jeopardize national survival or regional peace. While the UN has not yet intervened, legal precedents support multilateral dispute resolution under international water law. Thus, Pakistan’s call for UNSC engagement is grounded in both treaty obligations and the broader responsibility of the Security Council to maintain peace.
