The Messaging from Putting the IWT in ‘Abeyance’
May 6, 2025

Context

  • On April 24, India announced the suspension of the Indus Waters Treaty (IWT) of 1960, declaring it would hold the agreement in abeyance until Pakistan ceased its support for cross-border terrorism.
  • This decision, following the Pahalgam terror attack of April 22, marked a significant departure from India’s traditionally cautious approach to the IWT, a cornerstone of India-Pakistan relations.
  • While the term abeyance suggests a temporary suspension with the option of reinstatement, it raises critical legal, diplomatic, and strategic questions, shedding light on India’s evolving tactics in addressing its complex relationship with Pakistan.

The Legal Context and Meaning of ‘Abeyance’

  • The Legal Context
    • The term abeyance, as invoked by India, finds no grounding in the formal language of international law.
    • The IWT itself, as well as the Vienna Convention on the Law of Treaties (VCLT) of 1969, does not recognise such a concept.
    • Notably, India is not a party to the VCLT, while Pakistan, though a signatory, has not ratified it.
    • International law, including the principles enshrined in the IWT, emphasises cooperation over unilateral action.
    • Articles XII(3) and (4) of the IWT stipulate that any modification or termination of the treaty requires mutual consent, a scenario that appears unlikely given the current diplomatic stalemate.
    • Moreover, while the VCLT allows for suspension or termination of treaties under specific exceptional circumstances, such as a material breach (Article 60), impossibility of performance (Article 61), or a fundamental change in circumstances (Article 62), India has not formally invoked these provisions.
  • Meaning of ‘Abeyance’
    • Its use of abeyance, therefore, appears more symbolic than legally enforceable, effectively serving as a political statement rather than a legitimate suspension of treaty obligations.
    • In practical terms, India’s decision may enable it to halt cooperation on critical operational aspects of the treaty.
    • This includes withholding data on water resource projects and flood forecasting, actions that could temporarily jeopardize Pakistan’s water security.
    • Additionally, India might proceed with certain infrastructural activities, such as flushing silt from its reservoirs, without notifying Pakistan as required under the IWT, further straining bilateral trust.

Strategic Calculations and the ‘Two-Level Game’

  • India’s choice of ‘abeyance’ reflects a strategic balancing act. Domestically, the decision likely aimed to demonstrate a swift and robust response to terrorism, providing solace to a grieving nation.
  • Internationally, it signals India’s mounting frustration with Pakistan’s intransigence.
  • This move also appears designed to free India, at least temporarily, from the procedural constraints that Pakistan has frequently used to delay critical water infrastructure projects, such as the Kishenganga and Ratle hydropower initiatives.
  • The strategy, however, is fraught with risks. Pakistan, heavily reliant on Indus waters, has already characterised India’s actions as an existential threat, potentially inflaming tensions in an already volatile relationship.
  • The current political instability in Pakistan, exacerbated by internal dissent, economic challenges, and efforts to internationalise the Kashmir dispute, further complicates India’s calculations.
  • Whether India’s abeyance will exert meaningful pressure on Pakistan remains an open question.

Potential Ramifications for India

  • Legal and Diplomatic Challenges
    • Domestically, India’s move has resonated powerfully, aligning with public sentiment and garnering widespread political support.
    • Yet, beneath this immediate approval lie deeper concerns.
    • On the international stage, unilaterally undermining the IWT risks exposing India to legal challenges before the Permanent Court of Arbitration or the International Court of Justice.
    • Such a development could tarnish India’s reputation as a responsible global actor committed to international norms.
  • Environmental Concerns
    • Equally critical are the environmental and social risks.
    • Fast-tracking water infrastructure projects to consolidate India’s water rights, while politically expedient, may sideline essential environmental reviews and public consultation processes.
    • The Indus basin, rich in biodiversity and seismically sensitive, could face significant ecological damage, undermining long-term sustainability and the very national security the strategy seeks to bolster. 

The Path Forward: Balancing Security and Responsibility

  • As India navigates this delicate terrain, it must weigh immediate security imperatives against broader geopolitical and environmental considerations.
  • While strong rhetoric and decisive action may satisfy domestic demands, lasting solutions to cross-border terrorism require a nuanced approach.
  • India’s future strategy should prioritise reinforcing its standing as a responsible democracy that champions both environmental stewardship and international law.
  • In this context, the IWT abeyance serves as a double-edged sword: it offers short-term tactical gains but carries long-term strategic risks.
  • To maintain credibility and avoid unintended consequences, India must carefully craft its narrative, ensuring that any operational steps remain within the bounds of legal defensibility and environmental prudence.
  • Simultaneously, diplomatic channels must remain open to manage tensions and prevent the situation from spiralling into open conflict.

Conclusion

  • India’s decision to hold the Indus Waters Treaty in abeyance marks a pivotal moment in its bilateral relationship with Pakistan.
  • While it demonstrates a tougher stance against terrorism and asserts India’s strategic interests, it also exposes complex legal, environmental, and geopolitical challenges.
  • The true test lies ahead: can India leverage this strategy effectively without compromising its commitment to international norms and ecological sustainability?
  • The answer will shape not only India’s regional influence but also its global reputation in the years to come.
