IWT and Simla Agreement ‘In Abeyance’

 Why in News?

• On April 25, 2025, in retaliation to the terror attack in Pahalgam that killed 26 Indian tourists, India declared that:
  • The Indus Waters Treaty (IWT) of 1960 would be held “in abeyance”.
  • It may also consider holding the Simla Agreement in abeyance as part of broader diplomatic retaliation against Pakistan.
• Pakistan responded by stating it would also consider holding all bilateral agreements with India in abeyance, including the Simla Agreement.

 Introduction to the Issue

India has invoked a rarely used diplomatic tool — suspension without termination, or abeyance — to express its displeasure over cross-border terrorism and Pakistan’s perceived lack of good faith in fulfilling treaty obligations. This diplomatic stance affects two significant international agreements:

1. Indus Waters Treaty (IWT), 1960
2. Simla Agreement, 1972

Both agreements are foundational to India-Pakistan water sharing and peace processes, respectively. Their suspension has legal, strategic, and geopolitical implications that merit attention from legal aspirants.

1. What Does ‘In Abeyance’ Mean?

• Definition: “In abeyance” refers to a temporary suspension or withholding of a treaty or agreement without terminating it.
• It does not cancel the agreement but renders its obligations non-binding temporarily.
• This move is not codified under formal international treaty law but is practiced in diplomacy as a political signal of protest or pressure.

1. Indus Waters Treaty (IWT) in Abeyance

 Legal Background:

• The IWT governs the distribution of water from the Indus and its tributaries between India and Pakistan.
• The treaty was signed in 1960, with the World Bank as a guarantor.
• Under Article XII, the treaty can only be modified or terminated through mutual agreement between both governments.

🇮🇳 India’s Position:

• India has cited a “fundamental change in circumstances” — a clause recognized in international treaty law (Article 62 of the Vienna Convention on the Law of Treaties, VCLT).
• The Jal Shakti Ministry’s letter to Pakistan claims:
  • Altered population demographics
  • Energy needs and climate change
  • Pakistan’s continued support for terrorism
  • Failure to act in good faith
• India maintains that terrorism undermines trust, making the IWT untenable in its current form.

🇵🇰 Pakistan’s Reaction:

• Pakistan stated that if India holds the IWT in abeyance, it will consider doing the same for all bilateral treaties, including the Simla Agreement.
• Pakistan may attempt to trigger dispute resolution mechanisms built into the treaty.

III. Legal Framework: Vienna Convention and ICJ Precedents

 Vienna Convention on the Law of Treaties (VCLT), 1969:

• Governs the termination, suspension, or modification of treaties.
• Article 62 provides for termination/suspension based on “fundamental change of circumstances”.
• But these circumstances must:
  • Be unforeseen
  • Substantially alter the obligations
  • Be internal to the treaty (i.e., within its scope)

 ICJ Rulings – High Bar for Suspension:

• In Nicaragua v. United States (1984):
  • Nicaragua argued for a treaty suspension citing external political changes (U.S. support for Contra rebels).
  • ICJ rejected the claim, stating the change must relate to the treaty’s subject matter.
• In Gabčíkovo–Nagymaros Project (1997):
  • ICJ ruled that a dam dispute between Hungary and Slovakia must be resolved within treaty mechanisms, not via unilateral acts.

1. Simla Agreement: Legal Status and Strategic Importance

 Key Provisions of the 1972 Simla Agreement:

• Signed after the Indo-Pak war of 1971, it aimed to establish peaceful bilateral relations.
• Two critical provisions:
  1. Resolve issues bilaterally
  2. Recognize the Line of Control (LoC) in Jammu & Kashmir

🇮🇳 India’s Perspective:

• India has long considered the Simla Agreement as the cornerstone of bilateral ties, especially to counter internationalization of Kashmir.
• However, Pakistan has frequently violated the agreement, such as during:
  • Kargil War (1999)
  • Frequent references to international bodies

 Legally Binding or Not?

• The agreement is not enforceable like a treaty under international law.
• It is often described as a “best endeavour clause”, meaning:
  • Parties pledge to work toward peace, but not in legally binding terms.
  • There is no enforcement mechanism like arbitration.

1. Implications of Declaring Simla Agreement in Abeyance

1. Diplomatic Fallout

   • Weakens any current diplomatic backchannel.
   • Reinforces India’s assertion that talks and terror cannot go together.

2. Impact on LoC Recognition:

   • The Simla Agreement underpins LoC as the de facto border.
   • Holding the agreement in abeyance might open up questions around border management.

3. Regional Stability:

   • May aggravate tensions during times of military standoff.
   • Reduces scope for conflict resolution mechanisms.

1. Dispute Resolution and International Law Limitations

Challenges to India’s Position:

• India’s claim of climate change or terrorism as changed circumstances may not legally justify treaty suspension under ICJ standards.
• International law is not enforceable unless both parties agree to be bound.

 Expert Opinion:

• Prabhanshu Ranjan, Jindal Global Law School:
  • “Dispute resolution is the key focus in international law.”
  • “The action India is taking is more political than legal.”

Conclusion

India’s decision to declare the Indus Waters Treaty and Simla Agreement in abeyance marks a bold diplomatic and legal maneuver aimed at pressuring Pakistan over its inaction against terrorism.

While such declarations do not amount to outright withdrawal, they signal India’s growing readiness to rethink post-colonial bilateral frameworks that no longer align with its national interest. However, under international law, India’s move is on uncertain footing, particularly given the stringent criteria set by ICJ for suspending treaties.

For CLAT aspirants, this issue is a prime example of the intersection of:

• International law (treaty suspension, ICJ jurisprudence)
• Indian constitutional powers (Articles 253, 73)
• Diplomatic strategy and statecraft
