IWT: UNSC should intervene in South Asian water dispute

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
