Self-Defence Clause in Global Law

Why in the News?

India and Pakistan agreed to cease all firing and military actions following precision strikes by India under Operation Sindoor as a Self-Defence against the Pahalgam massacre that killed 26 civilians.

About Right to Self-Defence under UN Charter:

  • The United Nations Charter generally prohibits the use of force under Article 2(4).
  • Article 51 provides an exception, permitting the use of force in self-defence if an armed attack occurs against a Member State.
  • The International Court of Justice (ICJ) in Nicaragua v. U.S. (1986) interpreted “armed attack” as the gravest form of the use of force.
  • The right of self-defence is subject to two key conditions:
    1. Necessity: The force must be essential to respond to an armed attack.
    2. Proportionality: The response must not exceed what is required to repel the attack.
  • Under Article 51, states must immediately notify the UN Security Council (UNSC) of any action taken in self-defence.
  • In India’s case, the May 7, 2025 missile strikes were described as a “measured response” to the Pahalgam massacre, implying invocation of Article 51, though not explicitly stated.
  • India’s May 8 briefing to 13 of 15 UNSC members was likely in fulfilment of this reporting obligation.

‘Unwilling or Unable’ Doctrine:

  • This is an emerging principle in international law, particularly after 9/11.
  • It allows a state to use self-defensive force against non-state actors operating from another state’s territory if that state is:
    • Unwilling or
    • Unable to stop the threat.
  • It was prominently invoked by the US:
    • In 2011 (killing of Osama bin Laden in Pakistan).
    • In 2014 (airstrikes on ISIS in Syria).
  • However, it is criticised by countries like Russia, China, and Mexico for undermining state sovereignty and the UN system.

India’s Stance:

  • India’s position is unclear but evolving. At a UNSC Arria Formula meeting in Feb 2021, India listed 3 conditions:
  1. The non-state actor has repeatedly attacked the state.
  2. The host state is unwilling to neutralize the threat.
  3. The host state actively supports or sponsors the non-state actor.
  • Legal scholars note it is uncertain if these conditions are cumulative or independent.
  • In response to the Pahalgam attack, India accused Pakistan of inaction and labelled it a safe haven for terrorists.
  • This suggests implicit reliance on the “unwilling or unable” doctrine, though it is not codified in customary international law.
[UPSC 2005] Consider the following statements:

1. The Charter of the United Nations Organization was adopted at Geneva, Switzerland in June, 1945;

2. India was admitted to the United Nations Organization in the year 1945;

3. The Trusteeship Council of the United Nations Organization was established to manage the affairs of territories detached from Japan and Italy after WWII.

Which of the statements given above is/are correct?

Options: (a) 1, 2 and 3 (b) 2 only* (c) 1 and 3 (d) 3 only
