India's Indus Waters Treaty Suspension Has Legitimacy

Fundamental and unforeseen changes in circumstances allow India to hold the treaty in abeyance

- STELLINA JOLLY

Following the terror attack of 22 April on civilians in Pahalgam that India traced to Pakistan, the Indian government announced that the Indus Waters Treaty (IWT) of 1960 would be held in "abeyance" with immediate effect. While 'abeyance' lacks a formal status in international law, the closest corresponding legal concept is 'suspension' under Article 62 (1) of the Vienna Convention on the Law of Treaties (VCLT). It recognizes a change in circumstances as a valid but narrowly constructed ground for suspending or terminating treaty obligations if: (a) the change is unforeseeable and fundamental and (b) radically transforms a party's obligations. Given these conditions, can India's actions be justified within the international law framework?
