India-Pakistan relations have once again entered a period of acute tension following the Pahalgam terror attack (April 22, 2026), raising critical questions of international law, state responsibility, and armed conflict that are directly tested in CLAT’s Current Affairs and Legal Reasoning sections. This article analyses the legal framework governing India’s options and the applicable international law principles.

International Law Principles u2014 CLAT Angle
1. State Responsibility and Non-State Actors
Under customary international law and the ILC Articles on State Responsibility (2001), a state is responsible for acts of non-state actors operating from its territory if it directs, controls, or fails to prevent such acts. The International Court of Justice (ICJ) articulated this standard in Nicaragua v. USA (1986) u2014 mere ‘effective control’ is required, not just general support.
For CLAT, remember: Pakistan’s alleged support for cross-border terrorism can be examined under this doctrine. India’s position is that Pakistan exercises ‘effective control’ over terrorist groups.
2. Article 51 u2014 Right of Self-Defence
Article 51 of the UN Charter permits self-defence “if an armed attack occurs” against a Member State. Post-9/11, the UN Security Council’s Resolution 1368 recognised that armed attacks by non-state actors can trigger self-defence rights. This is a crucial development tested in CLAT legal reasoning passages.
Two conditions must be satisfied (Caroline Test, 1837):
- Necessity u2014 No other means available
- Proportionality u2014 Response must not be excessive
3. Indus Waters Treaty Suspension
The Indus Waters Treaty (IWT) 1960, brokered by the World Bank, allocates the western rivers (Indus, Jhelum, Chenab) to Pakistan and eastern rivers (Ravi, Beas, Sutlej) to India. India’s decision to suspend the treaty is legally controversial u2014 IWT has no unilateral exit clause. This creates a dispute that can go to the Permanent Court of Arbitration (PCA) or the International Court of Justice.
Simla Agreement u2014 Key Provisions
The Simla Agreement (1972) requires India and Pakistan to settle disputes through bilateral negotiations and prohibits unilateral changes to the Line of Control (LOC). It is often cited by Pakistan to resist international intervention. However, India argues terrorism is not a “bilateral dispute” but a global crime.

Frequently Asked Questions (FAQ)
Is India’s suspension of Indus Waters Treaty legally valid?
The IWT does not contain a unilateral exit clause. India’s suspension is legally contested. Pakistan can invoke PCA arbitration under IWT provisions. CLAT may test this as an international treaty law question.
What is Article 51 of the UN Charter?
Article 51 preserves the inherent right of individual or collective self-defence if an armed attack occurs against a UN member state, until the Security Council takes measures to maintain international peace.
How is CLAT testing India-Pakistan issues in 2027?
CLAT tests these through passage-based questions in Current Affairs and Legal Reasoning sections. Expect passages on international law doctrines with principle-application questions about state responsibility and armed conflict.
What is the Caroline Test in international law?
The Caroline Test (1837) established two conditions for lawful self-defence: necessity (no other means) and proportionality (response must not be excessive). It remains the foundation of customary international law on self-defence.
